Senses and meanings assigned to teaching training by egresses from the Institutional Program of the Initiation to Teaching Grant (PIBID)

André de Araújo Moraes, Virgínia Mara Próspero da Cunha — Tue, 23 Sep 2025 00:00:00 +0000

This study aimed to analyze the contributions of the Institutional Program for Teaching Initiation Scholarships (PIBID) to teacher training. In the theoretical framework, central aspects of teacher training and professional development are based on important contemporary contributions. The qualitative research involved 40 subjects who responded to a questionnaire, in addition to five interviewees. Data analysis was conducted in light of the theory of Meaningful Cores, based on the assumptions of Socio-Historical Psychology. The results pointed to the following as the main contributions of the program: the experience of teaching in the school context, the role of supervising teachers as co-trainers, the articulation between theory and practice, and the relevance of collaborative learning. It was concluded that PIBID, in conjunction with the initial training received in undergraduate studies, enhances teacher training that is more consistent and aligned with the demands of the school environment.

Plural Representations of Youthful Masculinities:

Mauricio Nazarete Lopes, Paula Regina Costa Ribeiro , Juliana Ribeiro de Vargas — Tue, 23 Sep 2025 00:00:00 +0000

In this article, we intent to problematize the dimensions of different musical styles and the (re)constitution of masculinities by young subjects (men). Thus, we aim to investigate representations of contemporary masculinities made visible by the narratives of seven young men who describe themselves as belonging to cultures related to the musical styles of Kpop, Rap and Rock. We understand culture as every manifestation of a human group, which means understanding different musical styles as cultural dimensions. As a methodological strategy, we used narrative interviews, which were carried out virtually, using tools that allowed video calls to be made. In the narratives of the young people, it was possible to see a distancing from representations of “traditional/hegemonic” masculinities and that sought other forms of plural/dissident/queer representations. As results, we highlight that, even the different musical styles mentioned make visible certain postures as representative of masculinity, young men (re)constitute meanings and (re)define, based on plurality, the exercise of masculinity.

THE ROLE OF TEACHERS IN THE COMPREHENSIVE TRAINING OF STUDENTS PARTICIPATING IN EXTRA CLASS PHYSICAL EDUCATION PROJECTS AT IFSUL/PELOTAS CAMPUS

Thu, 16 Oct 2025 00:00:00 +0000

ABSTRACT

This article presents the analysis carried out in a master's research on the role of teachers responsible for extracurricular Physical Education activities in the comprehensive training of students at Instituto Federal Sul-rio-grandense - Pelotas. Having Dialectical Historical Materialism as a theoretical-methodological reference, the Discursive Textual Analysis was used to analyze the interviews conducted with three teachers in charge of extracurricular teaching projects in Physical Education. The dialectical movement has made it possible to state that the extracurricular projects enhance community-related experiences, help promote criticality and, by means of the bond provided, result in students' sense of belonging. Hence, the teacher’s role is fundamental for fostering these experiences, thus contributing to students’ comprehensive training.

Keywords: pedagogical practice; comprehensive training; extra class.

Autist identification card

Sat, 11 Oct 2025 00:00:00 +0000

This article aims to investigate the issuance of Identification Cards for People with Autism Spectrum Disorder (Ciptea), by the Federation Units, based on Federal Law No. 13,977, of January 8, 2020 (Romeo Mion Law), as well as the reflection of the provision of this document by the Municipalities, with the aim of analyzing the construction of statistical data on the number of people with autism in Brazil. The research revealed to us that Ciptea is a document that guarantees identification for the exercise of the right provided for in the National Policy for the Protection of the Rights of Persons with Autism Spectrum Disorder, known as the Berenice Piana Law (Law no. 12,764, of December 27 2012), as well as other established policies, whether at the state or municipal level, but it does not prove to be a facilitating instrument for the prevalence of people with autism in the national territory.

The The game as element of cultural heritage mediation

Dorcas Weber, Elane Pessoa — Tue, 23 Sep 2025 00:00:00 +0000

Games have been used as teaching resources in different educational contexts. I have this perception, added to the fact that games are part of the relationships between humans, this writing seeks to share a proposal for the production of games as a mediation resource on the theme of cultural heritage in the school context. For this, allies such as IPHAN, Uizinga, Bauman, Funari and Pelegrini, Vigotsky, Hall, Brougère, among others were sought. For this production, it was based on a previous research that points out the lack of resources on the subject. With this proposal, it is expected that teachers can have support and motivation to seek and create different proposals on the local cultural heritage.

Training in Vocational Psychology in the world

Mara Dantas Pereira — Mon, 13 Oct 2025 00:00:00 +0000

Despite advances in the job market, women face unique challenges in their career paths. The development of women’s careers is a significant topic for psychologists in vocational and professional guidance, spanning from initial aspirations to progression in the job market. This article discusses vocational psychology education from a gender perspective, highlighting the contribution of academic women in the field of Vocational Psychology. An increasing importance of the gender perspective in understanding women’s vocational behavior was found. A psychologist can adopt a dynamic approach to address women’s challenges in career choice, combating gender stereotypes and highlighting examples of successful women. A degree in Psychology is important for disseminating knowledge in vocational and professional guidance, and should consider the specificities of women’s career development in its curriculum.

Ana Paula de Oliveira, Michelle Engers Taube, Mary Sandra Carlotto — Tue, 23 Sep 2025 00:00:00 +0000

Death by suicide is a public health problem and its consequences have reached worldwide proportions. The present study aimed to identify the frequency and factors associated with suicidal ideation in university students in the health area. 246 students participated who answered an online form. The instruments used were a questionnaire with sociodemographic, clinical, academic and work data, academic stressors, Beck's Suicidal Ideation scale and the Perceived General Self-efficacy scale. The results, obtained through Multiple Linear Regression Analysis, indicated an explanatory model consisting of four variables: self-efficacy, thinking about dropping out of the course and the stressors economic costs related to the course and reconciling studies and family. Public and institutional health actions aimed at promoting and preventing the mental health of university students are suggested.

Competences and Online Laboratories

Mon, 20 Oct 2025 00:00:00 +0000

This work presents a systematic literature review aimed at listing the competences associated with the use of remote laboratories. The PRISMA model was employed to conduct the review, considering papers published in journals and conference proceedings between 2013 and 2023, and indexed in the ACM Digital Library, IEEExplore, Scopus, and Web of Science databases. Studies addressing competences in remote laboratories were included, while other document types, studies unrelated to the topic, or with irrelevant results to the research questions were excluded. The search in the databases was carried out in October 2023, yielding 953 documents, with 309 duplicates removed, and 609 documents removed during the screening process, adhering to the inclusion and exclusion criteria. From the 7 selected papers, 7 competences were identified across 3 distinct areas, linking their knowledge, skills, and attitudes. This study presents a set of competences related to remote laboratories, which can be used to further improve the development of these educational resources, as well as the pedagogical aspects of their application. However, further research in this area is needed to provide a more detailed description of the related competences.

Scientific Initiation

Bruna Bertoglio Lorenzoni, Tania Denise Miskinis Salgado — Wed, 01 Oct 2025 00:00:00 +0000

This paper analyses the Institutional Programs for Scientific Initiation Scholarships funded by the National Council for Scientific and Technological Development (CNPq). It discusses the funding of grants from the same Program, managed by the Dean of Research (PROPESQ) of the Federal University of Rio Grande do Sul (UFRGS) and the organization of two scientific events, the Scientific Initiation Hall (SIC) for undergraduate students and the UFRGS Youth Hall, which resembles a science fair, for students in basic education. These events are recognized by the academic and external community and provide opportunities for the exchange of ideas through the research carried out. The study, with a quantitative and qualitative approach, had theoretical support from authors such as Ana Maria Pessoa de Carvalho, Pedro Demo, Maria do Carmo Galiazzi, Julieta Calazans and Maria Nobre Damasceno to support the analysis, from the perspective of teaching through research and relevance of scientific initiation. It is concluded that UFRGS Youth Hall provides opportunities for the presentation of research carried out in schools, encourages the practice of research in the school environment and contributes to a closer dialogue between universities and schools.

The The Governance and Management Professor in/for Federal Higher Education

Cristina Novikoff, Valéria Marques de Oliveira — Thu, 25 Sep 2025 00:00:00 +0000

with emphasis on military higher education institutions. The central problem considers the discussion about inequalities in educational governance in a military context, specifically regarding civil teaching activities in the Humanities, to be emerging. The starting question is: what are the devices that legally support the materialization of governance of civil teaching activities in the barracks? Through a single case study anchored in the humanities, a corpus was developed based on theoretical, normative, documentary, and self-narrative sources. The analysis encompassed specialized literature, regulatory and legal policies, as well as decision-making processes related to teaching activities. The investigation verified that governance in the barracks defines the management of processes and people in a distinct way compared to civil governance. Dissonances were identified in teaching assignments, both in conceptual and normative aspects, when compared to assignments in civil public institutions and other military organizations. The divergent understandings about teaching assignments revealed they impact less on teaching autonomy than on scientific research, especially those associated with the humanities. The study points to the urgency of expanding the discussion about governance and management in the military context, contributing to a deeper understanding of the integration of civil teaching practices in the barracks. Thus, it seeks alignment between the educational legislation of federal higher education and that of the Brazilian Army, considering the ethical, professional, and humanized values defended in public life.

Os Jogos do Instituto Federal do Paraná

Matheus Amaral de Souza, Andréia Paula Basei — Sat, 25 Oct 2025 00:00:00 +0000

The Games of the Federal Institute of Paraná (JIFPR) is a sporting event held between students from the various campuses of the Federal Institute of Paraná (IFPR), which has existed for over a decade. This study aimed to understand the trajectory and characteristics of the JIFPR since the first edition held in 2010. To this end, documentary sources were analyzed - news, articles, publications and regulations - obtained through publications on the pages of the IFPR, from the JIFPR and on the Google search site using the descriptors "Games of the Federal Institute of Paraná", "JIFPR", "JIFPR + year" and "Regulation JIFPR + year". The research revealed: the insufficiency of studies on the event; the growth of the event with each edition, both in terms of the number of participating campuses and the number of students; the principles underlying the organization are anchored in democratization, integration, building values and education. It is concluded that the JIFPR is an already consolidated event that reflects the institutional policy in its principles, purposes and conceptions presented in the documents advocating the whole formation of students.

New Sociabilities, networks, and technology

Cyntia Barbosa Oliveira, Marcus Vinicius Spolle — Thu, 25 Sep 2025 00:00:00 +0000

Based on Donna Haraway's cyborg framework, where the author explores the interaction between individuals and technology, we engage in a discussion regarding algorithmic racism. We argue that as individuals become hybrids through the integration of technology into their daily lives, almost as an extension of their bodies, technology also plays a role in transforming and concealing long-standing racist practices in society. Thus, algorithmic racism operates by relegating Black cyborgs to processes that were already familiar before the hybridization of individuals and technology: discrimination, racism, and oppression. We also highlight the bibliography compiled from female theorists, many of whom are also Black, underscoring the need to bring attention to theoretical and critical discussions of cyborgs that are marginalized.

Educação Estética e Modelagem no Ensino de Ciências

Tue, 23 Sep 2025 00:00:00 +0000

O presente artigo descreve uma experiência vivenciada, por meio de uma proposta de ensino, por estudantes do 8º ano dos anos finais do Ensino Fundamental sobre a temática da puberdade, utilizando como método de ensino a Modelagem na Educação Matemática e na Ciência. Teoricamente, analisa e discute o desenvolvimento e os resultados da proposta a partir da noção de estética, vista como uma forma de se conhecer e de se significar, considerando a Educação Estética como um meio de educação humanizadora. Por meio da Modelagem na Educação, instigados com a letra de uma música, os estudantes ilustraram um corpo humano em tamanho real e expressaram as mudanças físicas e emocionais ocorridas na etapa da puberdade, demonstrando, em seus modelos, senso estético voltado à sensibilidade. A partir da Estética, os estudantes relacionaram as questões emocionais e humanas com os conteúdos estudados envolvendo a temática da puberdade, o que contribuiu ao processo de se auto-conhecer e respeitar a si e ao outro. Com isso, foi possível perceber a importância da disseminação da Educação Estética na Educação Básica de forma transversalizada com os diferentes componentes curriculares, potencializando os processos de ensino e de aprendizagem e desenvolvendo a capacidade de sentir, de significar-se e de expressar-se livremente.

External assessments

Carla Vargas Bozzato, Rosangela Inês Matos Uhmann — Tue, 30 Sep 2025 00:00:00 +0000

Assessments have occupied centrality in the agendas of the country's education networks in these first decades of the 21st century. The qualitative approach research aims to investigate the implications of external assessments in the pedagogical work of Natural Science Teaching teachers to reflect the assessment of learning and the teaching-learning process. Thus, the data were obtained from a semi-structured interview with high school teachers from four public basic education schools in the city of Pelotas-RS. The content analysis indicated four categories, namely: i) external assessments and pedagogical practices in Science Teaching; ii) external assessments and Science Teaching; iii) external assessments and learning assessment; and, iv) external assessments and teachers. The results indicate that these assessments are ubiquitous in schools, serving to guide pedagogical work actions, and may lead to curricular reductionism. From the analysis it is noted that these assessments take on a political dimension based on accountability, supervision and control.

Adolescent brazilians’ emotional responses to the covid-19 pandemic on digital media

Sylmara Castro Vianna, Pedro Donizete Colombo Junior — Tue, 23 Sep 2025 00:00:00 +0000

This article is part of a master’s thesis that investigated emotional responses of 9 Brazilian adolescents between 15 and 17 years old to news shared in digital media on the topic of Covid-19. This is a multiple case study with semi structured interviews that included publications related to the virus in order to identify and analyze participants emotional responses based on the theoretical work of Ekman, Damásio and Bellocchi. The results demonstrated sadness, surprise, and contempt. Anger, contentment, fear, and aversion were less frequently expressed. These emotions emerged in response to attitudes of persons who refused to comply with protective measures against Covid-19; rapid spread of the disease and its repercussions on digital media; and the number of cases reduction with in-person activities returning. This study may contribute to reflections for strategies that minimize the impacts of the post-pandemic context in adolescents lives and the digital media influence over them.

The challenges for scientific literacy in the Society of Ignorance: report of discussions in a postgraduate course.

Juliana Fraga, Marcelo Eichler — Tue, 23 Sep 2025 00:00:00 +0000

This article aims to highlight the challenges of scientific literacy in basic education, through the synthesis, analysis and reflection of the themes addressed during a postgraduate course in the area of science education. To achieve this goal, we adopted a qualitative approach that integrates theoretical analysis, classroom discussions and reflections on practical experiences in the educational setting. The article explores some essential questions about the driven increase in ignorance and its ramifications for education and society, especially in the face of technological advances and the rapid spread of misinformation and disinformation on digital platforms. In this sense, based on class discussions, we identified some of the main challenges that science educators may face when working with scientific literacy in different school contexts. Finally, we suggest that being aware of these challenges can be a first step towards facing emerging problems, aiming to inspire other pedagogical actions that start from ignorance to produce knowledge.

A linguagem literária na textualização de discursos sobre questões sociocientíficas na literatura infantil

Mon, 06 Oct 2025 00:00:00 +0000

Neste artigo é apresentado um recorte da pesquisa de doutoramento cujo objetivo foi a análise da linguagem literária na constituição de discursos sobre questões hídricas textualizadas em livros ilustrados de Literatura Infantil, com base na Análise Crítica do Discurso e na Semiótica Social. Assume-se as questões hídricas como questões sociocientíficas e fundamenta-se em autores que cooperam no entendimento da linguagem literária como essencial às abordagens de QSC, principalmente das crianças que vivem em “zonas de sacrifício socioambiental”. Os resultados apresentados referem-se a um dos livros que integram o corpus da pesquisa e apontam para a textualização da função utilitarista do rio para as populações, bem como de sua dimensão afetiva, por meio de referências a memórias, histórias de vidas e sonhos das populações. Nossas análises evidenciam que a Literatura Infantil é um território potente que possibilita abordagem de questões sociais complexas e controversas com sensibilidade e profundidade.

Conceptions and practices of teachers in Professional and Technological Education

Evelize Dorneles Minuzzi, Renato Xavier Coutinho — Mon, 20 Oct 2025 00:00:00 +0000

This article aims to investigate teachers' conceptions of Integrated Professional Practice - PPI, which is present in the didactic-pedagogical organization of all integrated technical courses at the Federal Institute Farroupilha - IFFar. Regarding the methodological design, this study is based on the domains of a qualitative approach, with an exploratory and descriptive objective and characterized, in terms of procedure, as a field research, as semi-structured interviews were used, applied to a group of teachers , whose data were analyzed according to Bardin's proposal. The results show a superficiality regarding the concept of PPI and a dissociation of it with the materialization of the integrated curriculum, despite the advances, there is still a strong interference from the disintegrated didactic-pedagogical organization and disciplinary. Therefore, it is essential to invest in the legitimization and strengthening of its essential elements and, at the same time, institutionalize them as epistemological and methodological clues to open up the successful opportunity and the movement to materialize the integrated curriculum through PPI.

Sun, 05 Oct 2025 00:00:00 +0000

Women have faced barriers and stereotypes, especially in careers related to Science, Technology, Engineering, Art and Mathematics (STEAM). Discussions about empowerment and promotion of female representation highlight spaces that lack diversity and need awareness for social transformation. This article deals about collaborative actions of teaching and extension projects at University Federal of Pelotas (UFPel), whose objective was to plan, propose, analyze and report a teaching proposal in Basic Education, through historical recovery and contributions in the Science by actress and inventor, Hedy Lamarr, whose invention gave rise to wi-fi and bluetooth. As a methodological strategy, the Three Pedagogical Moments were used in dialogued actions based on Technologies of Information and Communication (TIC) and in knowledge mediation. Participation in the proposed activity, receptivity and engagement were the result of how much the content covered influences the students' lives and daily lives. In this way, relevant discussions, which corroborate the Sustainable Development Goals (SDG 5) were provided, but they do not determine a how, but rather a possibility of integration, approach and critical discussion of the topic.

Sound Atelier: proposal of a strategy based on STEAM Education for the learning of sound waves

Emerson de Souza Queiroz, Marcus Vinicius Pereira — Tue, 23 Sep 2025 00:00:00 +0000

Although the study of sound waves is relevant, practical applications are still incipient considering the abstraction of the theme. This research aims to propose a didactic strategy for the teaching of sound waves through STEAM education, which resulted in a video to present the Sound Atelier - a collaborative learning environment for the pedagogical use of the 14-string musical instrument - a zither in puzzle format. In addition to this instrument, six textual artifacts were made – assembly manual, pedagogical itinerary and four learning dynamics. The video as an educational product was applied remotely with 23 public Basic Education teachers in the areas of Mathematics and Natural Sciences. As a result, we can say that the product met the expectations to present the potential of the Sound Atelier, making the artifacts associated with the didactic strategy viable and applicable, as evidenced by the responses of the participating professors.

Theater in chemistry teaching: a playful and affective way of learning

Francisco José da Costa Costa, Maria Goretti de Vasconcelos Silva Silva — Tue, 23 Sep 2025 00:00:00 +0000

This research aims to analyze the potential of using theater as a strategy to promote students' affective engagement with chemical content, promoting playfulness and affectivity in chemistry teaching. The methodology involved qualitative and exploratory research, of an applied nature, with the production of plays by students from a public high school in Acaraú-CE, using content from the history of chemistry. Semi-open questionnaires were administered after the presentation of the plays to identify acceptance of the methodology, affective perceptions and influence on learning. The data obtained was analyzed and discussed in the light of Vygotsky and other researchers, taking into account the students' motivation and affection for the knowledge of chemistry based on the performance in the theater. The results show that theater is a humanized and playful teaching strategy with the potential to trigger positive emotions, establish affectivity in relation to the content and make learning enjoyable and effective.

Between Memories and Resistance:

Nathalia Vieira Ribeiro — Tue, 23 Sep 2025 00:00:00 +0000

This article proposes to analyze different theories about memory, from a critical and dialogical perspective, paying attention to, above all, the approaches of pioneering scholars on the subject, with the aim of discussing their concepts, crossed by different authors, in the attempt to discuss the dimension narrative of the memory of historical traumas. In this way, this work deals with the crossings between the practices of obliteration and manipulation of reminiscences of traumatic events of a historical dimension, through the uses and abuses of memory, seeking to understand that, just as the narrative dimension of memory contributes to silencing and exclusions in the public sphere, their contributions with regard especially to “counter-history”, can be taken as tools for social transformation in the present, through the rewriting of the past.

Campeonato Estudantil Gaúcho (1970-1980)

Raquel Valente de Oliveira, Janice Zarpellon Mazo — Tue, 14 Oct 2025 00:00:00 +0000

This study aimed to investigate how the process of composition of Campeonato Estudantil Gaúcho (CEG) and its first editions took place between the 1970s and 1980s. For this, interviews with agents who participated in the event at the time were collected and analyzed. In addition, information from documentary and digital sources also contributed to the research. The interpretation of historical evidence from the different sources showed that the first initiatives for the creation of CEG took place in the early 1970s, along with the Assessoria Técnica do Departamento de Educação Física e Desportos (DED), da Secretaria da Educação e Cultura do Rio Grande do Sul (SEC). Many of the sports practices and cultural representations produced in/by the event were anchored in the educational political conjuncture prevailing in the country at that time. CEG is the precursor of the Jogos Escolares do Rio Grande do Sul, a school sports event currently held at state level.

Guidelines for Community Outreach Programs in Brazilian Higher Education

Ronaldo César Darós, Giovanna Pezarico, Marlize Rubin-Oliveira — Tue, 30 Sep 2025 00:00:00 +0000

The purpose of this essay is to reflect on the history of Higher Education in Latin America and identify its relevance to the Guidelines for Extension in Brazilian Higher Education. The primary responsibility of universities is to produce and disseminate knowledge, and their structures are shaped by modern, eurocentric rationality. During the colonial period, this rationality was established in Latin America, resulting in the development of practices and epistemes that led to modernity and colonization on the continent. Although the Brazilian constitution requires teaching, research, and extension to be inseparable, there was no clear definition of how the dimension of university extension should be carried out until recently. Against the backdrop of university structures that have been influenced by modernity and colonization, and have experienced crises in public higher education in recent decades, the National Education Council established the Guidelines for Community Outreach Programs in Higher Education in 2018. The guidelines provide opportunities to move beyond the dependence on models that Brazilian universities have relied on since their inception.

Assessment

Jessica Pavao Antoniassi, Edson José Wartha — Wed, 15 Oct 2025 00:00:00 +0000

In this study, we want to share our doubts, anxieties and conceptions about assessment. From an analysis of historical contexts, it was possible to identify some conceptions and traditions of evaluation, as well as how they materialize in the classroom. The work brings the main characteristics of four historical moments of assessment: measurement phase, defined objectives, value judgment and negotiation. Many evaluative actions experienced in current school contexts, more specifically in science teaching, have been happening for many decades in the same way, and, as teachers today, we seek ways to break with these practices. At the end of this study, contrary to what we intended, doubts and anxieties remain; but now it was possible to identify ourselves as students, teachers and researchers in this evaluation process, aware of the genesis of assessment in science teaching, allowing us to reflect on our experiences and conventions.

Active Methodologies in Object Oriented Programming Learning

Fábio Aiub Sperotto, Claudio Cleverson de Lima — Tue, 30 Sep 2025 00:00:00 +0000

In the different levels of training in the area of Computing, introductory programming disciplines are present, including the object-oriented paradigm. In this paradigm, learning difficulties are observed when students are submitted to a more abstract reasoning, which can cause failure and dropout. On the other hand, active teaching-learning methodologies aim to provide new strategies to mitigate these difficulties. The aim of this study was to analyze how active methodologies can help in a better understanding of the object-oriented paradigm. The research was carried out in an exploratory way, in publications in the area, and through questionnaires applied in a discipline taught [omitted for review]. As a result, it was found that peer instruction strategies and learning based on problems and projects are considered positive in supporting object-oriented programming learning. These methodologies tend to be the most used according to related publications and through analyzes of [omitted for review] teaching practice, reducing learning difficulties.

Environmental education is a well-established discipline that emphasizes man's relationship with the natural environment. This study aims to analyze the publications of the last 20 years on environmental education in the countryside, through bibliometric analysis. The research was developed from the application of the bibliometric methodological procedure, on the Web of Science platform. The search for keywords sent us a total of 142 publications in the period 2002 – 2022. We found 10 research areas most addressed by the subject under study. The retrieved articles were published in more than 160 journals. The country with the highest representativeness in the percentage of publications was Brazil with 20 records. The analysis of co-occurrence networks of keywords showed 7 clusters. The study revealed that research related to environmental education in the countryside is still scarce and requires a new approach.

Renata Porcher Scherer, Luciana Rodrigues Nogueira , Sandra Machado — Tue, 23 Sep 2025 00:00:00 +0000

The present work is a report of a pedagogical experience of an Integrated Seminar carried out in the scope of an Integrated High School in Environmental Control Technician Course. The proposed work took place in an interdisciplinary way involving five disciplines. The theoretical and methodological perspectives that supported the work developed were studies on integrated high school education with active strategies based on the methodology of contextualization of learning. The work was carried out throughout 2021 with two first-year classes and due to the COVID-19 pandemic, it was carried out entirely in the emergency mode of remote learning. At the end of the reflection, the importance of interdisciplinary work and the role of young people in the construction of a more democratic education is pointed out.

PNAE and school feeding in pandemic (Covid-19): reports developed in Umuarama-PR

Tue, 23 Sep 2025 00:00:00 +0000

The objective of this work was to evaluate the actions of the Municipality of Umuarama/PR in conducting the National School Feeding Program (PNAE), in the pandemic period, resulting from Sars-CoV-2. Group 1, family farmers, reported losses resulting from the restrictions imposed by the pandemic, although they maintained deliveries to the PMC. Group 2, composed of students, exposed the importance of school meals and the impacts of remote teaching. Group 3, parents or guardians, reported that the PMC helped to maintain the families' diet, due to the decrease in income. Technical support and/or educational actions are needed to minimize observed food losses (Groups 1 and 3) and ensure food security.

Application of Problem Based Learning (PBL) on Computer Architecture on a Professional Technical School

Alexandre Diefenthaler — Tue, 23 Sep 2025 00:00:00 +0000

This article presents the results obtained from the answers of students about the application of PBL methodology – Problem Based Learning – on part of the content of the Computer Architecture discipline, in a technical school, by a didactic sequence (DS). The article also presents and analyzes the results on the application of the PBL methodology and the possible contribution to the training of first-year students at a public technical school, located in the County of Guaíba, Rio Grande do Sul, Brazil, during the period of March to June 2022, in the content part of the Computer Architecture discipline, specifically, the construction of computational logic circuits based on the interpretation of logic tables. Four classes were selected, divided into two pairs in two shifts, afternoon and evening, in which one of each pair received the content formatted in a didactic sequence and applied in the classroom according to the PBL methodology. The research methodology used was mixed, with quantitative and qualitative methods in a single study, seeking to analyze the convergences and the divergences of data obtained in the two classes with the PBL methodology, and used as an instrument for evaluating the questionnaire, made available to students after the application of DS. This article analyzes the responses to the questionnaire questions. The data are presented through graphs and discussed in the light of some authors on the topic. Finally, this article also presents final considerations and conclusions about the perception of students about how PBL can influence learning.

Os sentidos da carreira docente

Ivan Bremm de Oliveira, Giovanni Felipe Ernst Frizzo — Mon, 13 Oct 2025 00:00:00 +0000

The objective of this research was to analyze the meanings of the teaching career for PE teachers at the Pelotas Municipal Education Network (RMEPel) with 20 or more years of teaching. For this purpose, we adopted the theoretical current of Historical-dialectic Materialism. This is a case study carried out with 11 PE teachers with 20 or more years of experience in the teaching career. To collect data, we used semi-structured interviews and, within the scope of data interpretation, content analysis. We then point out the following as meanings for a teaching career: a) Professional and personal fulfillment as a teacher; b) Relationships established with students; c) The existence of a Gift/Vocation for teaching and, d) Public and Private throughout the teaching career. Finally, we infer that, despite the professional devaluation perceived throughout their careers, there are still meanings to the career and teaching work and, as long as there are meanings, there will be a fight for greater appreciation of the teaching profession.

Bússola na Trilha Certa

Tue, 23 Sep 2025 00:00:00 +0000

The main purpose of the project was to encourage the practice of outdoor sports in order to reduce school demotivation in high school. The methodology was divided into activities related to motivational, historical, technical aspects and curiosities about outdoor and adventure sports, orientation and navigation (notions of cartography and compass) and practical activities of hiking, mountain biking and canoeing. As a result, an academic impact can be seen related to the motivation of the students of the XXXXX and external partners in order to reduce the pressure under which young people are currently inserted and the possibility of relating the contents of the curricular units with sports activities and work activities, that is, a social impact of stimulating students in order to reduce depression, stress and school dropout.

Entre o ensinar e o aprender

Ivana Almeida Serpa, Rochele da Silva Santaiana — Sat, 11 Oct 2025 00:00:00 +0000

This article aims to analyze the shifts in the field of pedagogical planning in initial training in Pedagogy, taking as its empirical corpus the curricular documents of 2004, 2008, 2014, and 2021 from the Universidade Estadual do Rio Grande do Sul. Inscribed in the post-structuralist perspective and Foucauldian studies, the theoretical-methodological stakes of this documentary research operated with the conceptual-analytical tool of theoretical and practical governmentality. The analyses show that the field of pedagogical planning has moved from being silenced in the Pedagogy curriculum to increasingly aligning with the neoliberal discourses of business management and the pedagogy of competencies. As a result, we advocate for regaining the power of pedagogical planning as a practice that mobilizes teaching know-how based on the exercise of hyper-critical thinking against contemporary neoliberal logic.

Development of software or applications for people with cerebral palsy and its implications for learning Natural Sciences and Mathematics

Dilson Ferreira Ribeiro, Isabel Cristina Machado de Lara — Mon, 29 Sep 2025 00:00:00 +0000

This article presents a meta-analysis through a Systematic Literature Review on software or applications that benefit the learning process of people with cerebral palsy (CP) in the areas of Natural Sciences or Mathematics. It aims to investigate the implications in the development of Augmented, Virtual or Mixed Reality resources, designed to ease the difficulties imposed by disability. By combining 13 descriptors, 54 searches were carried out in 10 national and international databases. After this process, a thesis, eight dissertations and four articles constituted the corpus of analysis categorized through Discursive Textual Analysis. The development of the review shows that there are few productions involving this theme. The analysis found some benefits of these resources, minimizing the barriers imposed by disability. However, it brings up the need for application or software creators to understand the physical and cognitive conditions of people with CP.

State of the Question about the teaching of Physics in the curricular component of Science in the final years of Elementary School

Joana de Moura Pasinatto, Rafaele Rodrigues de Araujo — Tue, 23 Sep 2025 00:00:00 +0000

The present research sought to investigate the State of the question regarding the teaching of Physics in the curricular component of Science in the final years of Elementary School (ES), through the discussions of the scientific community. The investigation took place through the analysis of 15 articles, based on the selection carried out in the Oasisbr search engine in the period 2001-2022. After reading and analysis, the articles were classified into three categories: Significant learning of physical concepts in the Science curricular component in the final years of ES; Didactic strategies for teaching Physics in the final years of ES: Possibilities based on the use of experimentation and/or technology; Didactic materials for teaching Physics in ES. From the analyzes and discussions, we realized that there are countless possibilities of materials and strategies that influence the teaching and learning process. In addition, the choices of strategies and materials are related to the search for meaningful learning. Furthermore, no studies were found about the perceptions of teachers who teach Science about the teaching of Physics, which becomes an emerging issue to be investigated.

Internationalization at home from a Global South perspective: a bibliometric study

Marcio Watanabe, Marcia Regina Selpa Heinzle — Tue, 23 Sep 2025 00:00:00 +0000

This research is part of the contemporary debates on the internationalization of basic and higher education and the challenges facing the transformations resulting from globalization. This study aimed to present a bibliometric analysis of scientific publications linked to the Web Of Science, SCOPUS, and ScIELO on the subject of internationalization at home (IH). We also investigated the gaps, possibilities, and trends in IH research in the global context at the same time as establishing links to the context of the Global South. The study method is qualitative, bibliometric, and exploratory, with the data represented in tables, graphs, and bibliometric maps. The following main findings stand out: 1) the significant increase in publications on IH; 2) the low representation of researchers from countries in the Global South, and, hence, 3) the lack of specific publications aimed at the geopolitical context of the Global South. In short, as a study subject, IH shows promise, indicating a broad field for further research in the context of the particularities of the emerging countries of the Global South.

Singularities of Turnen in schools in Pelotas/RS (1880-1920)

Alice Beatriz Assmann, Tuany Defaveri Begossi, Janice Zarpellon Mazo — Sat, 27 Sep 2025 00:00:00 +0000

This historical investigation aims to understand the singularities of Turnen in schools in Pelotas from the 1880s to the 1920s. The state of Rio Grande do Sul stands out among the other states in Brazil with regard to Turnen. Apart from the capital, Porto Alegre, the city of Pelotas is a particular case in relation to Turnen in the state. With a regional bias, it focuses on a specific space and time, seeking to broaden the understanding of the process of introduction and diffusion of gymnastic methods in schools in Rio Grande do Sul. The categories of figurational analysis, by Norbert Elias, made it possible to identify approaches and distances from the codes established by Turnen's “good society”, associated with the intentions of school teaching.

Teachers’ meanings regarding “lives” as a context for their (self) continuing teacher education

Tayná Laureth, Roberta Andressa Pereira, Daniela Tomio — Wed, 01 Oct 2025 00:00:00 +0000

The popularization of lives during the coronavirus pandemic also created a context for continuing teacher training. Given this, we aim to understand the meanings that basic education teachers attribute to lives for their continued education, interpreting these meanings in relation to self-education. To do this, we carried out asynchronous online interviews with 24 Basic Education teachers, who participated in lives. With the analyses, we interpret that the lives promoted teachers' interest in their professional development, reflection on their teaching practice, the construction of their teaching identity and pedagogical dissemination to their peers. Among the unfavorable aspects, the commitment to the collective nature of continuing education was highlighted, which is limited in the live format. Finally, we understand that live broadcasts will continue beyond the social distancing requirements imposed by the coronavirus. Therefore, knowing and appropriating their potential in learning and research paths means committing to teacher training in our historical-social context.

The relationship between the imaginary about Science and scientists in the conceptions of elementary school students

Mon, 27 Oct 2025 00:00:00 +0000

This study aimed to analyze students' conceptions of science as a body of knowledge and their imagery of scientists. It used a qualitative approach, in which 85 sixth- and seventh-grade elementary school students from a school in the northwest region of the state of Rio Grande do Sul (RS) responded to a questionnaire with two questions: one discursive, about the concept of science, and the other objective, about the imagery of scientists. Through thematic content analysis of the open-ended question about the concept of science, the responses were divided into three thematic categories: - Science related to everyday life, with 21 Context Units (CUs); - Science content, with 15 CUs; - Subjects related to science, with 6 CUs. It was found that the students were able to relate science as a school subject, connecting it to other subjects and to their daily lives. It was possible to perceive that the students' conception of the scientist's imaginary is linked to the scientific stereotypes propagated by the media and during classes.

Sexuality of deaf women

Lidiane Augusta Ferrari Botteon, Maria Regina Momesso — Tue, 28 Oct 2025 00:00:00 +0000

Sexuality is a difficult issue to be discussed in the field of school education, especially when it comes to inclusion. The topic is also surrounded by prohibitions, myths, and taboos of all kinds. Students with disabilities seem to be even more invisible, as if they were asexual beings. Things get more difficult when there is no language shared among the deaf, the school, the family, and the society. Such situation opens space for post-truths, which makes dialogue and the subject knowledge of sexuality difficult. According to Foulcauldian studies, sexuality defines us as subjects and delineates us in our subjectivity (ies). The aim is to carry out a bibliographic study of dissertations, theses, and scientific articles from eight databases (PUC, SP; UFSCar; UNESP; USP; UNICAMP; SCIELO; CAPES and OASISBR), from 2011 to 2023, to verify how the constitution of deaf women and their relationship with sexuality is treated. The study is bibliographic, documental, qualitative, and based on the analysis of Foucauldian discourse from the third domain called genealogy of ethics. The review showed the scarcity of studies on sexuality and their need for more inclusive education.

Covid-19 e and the difficulties faced by students in integrated High school during social isolation

Emanoela Moreira Maciel, Catarina Angélica Carvalho Perreira — Thu, 09 Oct 2025 00:00:00 +0000

COVID-19, a disease caused by the new coronavirus is a respiratory infection of high transmissibility that can evolve from mild to severe cases, with the possibility of death. It has been considered a public health emergency by the World Health Organization (WHO). Because of COVID-19, preventive sanitary control regulations, including social isolation, became mandatory. In the educational field, onsite lessons became remote. Because of that, a psychological impact on students during the pandemic was observed in the school environment. The effects could still be observed after the end of lockdown. Thus, this study aimed at investigating the impact of the return of onsite activities on the mental health of students in the second year of Integrated High School (EMI), at a federal institution in Piauí. It is a field research of qualitative character, descriptive and explanatory nature, developed by means of semi-structured interviews, with the participation of 10 students from Integrated High School. The study took place during the Program for Post-Graduation in Professional and Technological Education (PROFEPT). The technique used for data analysis was based on Bardin’s model (1977). Results indicated, among other things, that the period of social isolation really aggravated the mental suffering of the participants and the return to onsite activities proved an adaptative challenge for these students. Researchers concluded that this period of pandemic caused plenty of learning difficulty for students in remote education, which reveals the importance of discussing mental health at schools.

The National Curriculum Parameters (PCN) and the Common National Curriculum Base (BNCC):

Lara Ronise de Negreiros Pinto Scipião, Felismina, Gabriela, Daniel, Maria José — Mon, 29 Sep 2025 00:00:00 +0000

Brazil has experienced, in the last 20 years, pedagogical proposals that involved, from the PCN (BRASIL, 1997) to the BNCC (BRASIL, 2017). Thus, the aim is to analyze the changes and contributions in the teaching and learning processes that occurred during this period. This is a qualitative, exploratory and descriptive research, through content analysis. To obtain the data, an electronic questionnaire was applied following the Likert scale model. The responses of 10 teachers from three municipal schools in Fortaleza-Ceará were analyzed. The analyzes show that the teachers know the PCN (BRASIL, 1997) of Mathematics and emphasize that the document contributed to their pedagogical practice. About the BNCC (BRASIL, 2017), the teachers report that they learned about the document during continuing education and use it in the preparation of the lesson plan. It is concluded that the PCN (BRASIL, 1997), as a guiding document, played an important role during the last two decades, in curricular orientation. The BNCC (BRASIL, 2017), as a normative document, needs to be better worked on/to improve teaching practice.

COVID-19 AND POST-GRADUATE PANDEMICS

Francisco das Chagas Silva Souza — Thu, 25 Sep 2025 00:00:00 +0000

Considering that the pandemic imposed changes in all sectors of society, a survey was conducted with students from the Professional Master's Degree Program in Vocational and Technological Education (ProfEPT) with the aim of knowing how the scenario imposed by social isolation interfered with the development of their field research and the application of their educational products. For the collection of information, narrative research was used through an invitation made to the master's students. We obtained seven texts that reported about the personal and academic impacts brought by the pandemic, and how their projects were restructured to be able to be executed in that adverse context. We conclude that, despite the difficulties faced, the master's students were able to reorganize, rework, and apply their educational products, constituting self-formative experiences.

The research method used was the case study and data collection instruments were a questionnaire and rubric, and the content analysis method to interpret the results. The results of this study highlight elements linked to supporting culturally focused activities, fostering reflection, broadening horizons, cultivating an inquiring mindset, and encouraging contextualized learning.

“Black… condemned”:

Thu, 23 Oct 2025 00:00:00 +0000

Judicial files are sources that make it possible to study different contexts and subjects, such as the field of crime in Brazilian slave society. This research objective is to reflect on using criminal proceedings as a historical source and their use in the classroom, presenting information such as how justice operates and aspects of everyday life. To achieve that objective, the methodology consisted of a literature review related to the contributions of these processes to historiography and history teaching. Using criminal cases as a source allows students to investigate and develop hypotheses about historical knowledge, taking an active attitude in the learning process. Therefore, this documentation contributes to the history discipline by building historical knowledge and stimulating students' critical thinking.

Estresse e resiliência em uma universidade pública

Fernanda Fátima Cofferri — Wed, 01 Oct 2025 00:00:00 +0000

This article identifies the situations that cause stress in teachers starting out in their university careers in order to understand whether they develop coping strategies or escape from these situations. Narrative qualitative research was used to analyze the accounts of eight beginning professors at a federal public university in Brazil. The data was organized into three categories of analysis: institutional culture and interactions with colleagues; student interactions and profiles; and coping or escape strategies. Institutional culture was perceived as an influential element in teachers' daily lives. Interactions with students show the democratization of academic access in recent years. The development of strategies to deal with and/or escape from adverse or conflicting situations was reported by teachers, including resilience. The conclusion is that the first years of teaching are a period of survival and discovery. Furthermore, the role of universities is fundamental in creating institutional programs that meet the training needs of university teachers, especially those at the start of their careers.

Discourses on the female body and sexuality expressed on a social network

Gleicy Kelly Felix Costa, Lucas Rossato, Fabio Scorsolini-Comin — Tue, 23 Sep 2025 00:00:00 +0000

The objective of this study was to analyze and understand how the female body and sexuality are represented in a social network based on the investigation of a page for women. This is a documentary study in which the questions sent to a page dedicated to female sexuality, on the social network Instagram®, between May 2019 and March 2021 were analyzed. The main themes produced from the analysis of the questions were: feedback regarding the page, pornography, gender ideology, women's health, female taboos in society, doubts about products and shame in purchasing them, complaints and content suggestions. These themes reinforce the prohibitions represented by the woman's body and the expression of her sexuality. It is noteworthy that the articulation between health education and social networks is especially relevant, as it can provide scientifically based information on sexuality and sexual health, helping women to reflect and understand themes that are seen as taboo by society.

DESENVOLVIMENTO DE MODELOS PARA AVALIAR O RISCO RELATIVO INSTANTÂNEO EM PACIENTES DE COVID-19 EM ESTÁGIOS INICIAIS E TARDIOS PARA USO COMO UM SISTEMA DE ESCORE

Thu, 23 Oct 2025 00:00:00 +0000

COVID-19, recognized as an outbreak in January 2020 and declared a pandemic shortly after, remains a clinical concern. This study developed a predictive model to classify patients by Relative Risk, which can be employed as a scoring system. It is a retrospective cohort study using data from patients admitted to the National Institute for Infectious Diseases "Lazzaro Spallanzani" (Italy) between January 29 and March 28, 2020. Cox Proportional Hazards models were created for patient admission (n = 218) and for the late stage of the disease (n = 385). The models were validated through Machine Learning and tested for violations of Cox assumptions and statistical power. Coefficients were extracted, and equations were derived to calculate the Relative Risk. For Early Stage Relative Risk (ERR), the following variables were used: Age Hazard Ratio (HR): 1.05 [95% CI: 1.02 - 1.08], RDW-SD (HR): 1.08 [95% CI, 1.02 - 1.14], Lymphopenia (HR): 3.23 [95% CI, 1.32 - 7.95], and Obesity (HR): 2.88 [95% CI, 1.08 - 7.69]. For Late Stage Relative Risk (LRR), the variables were: LDH (HR): 7.41 [95% CI, 3.00 - 18.28] and RDW-CV (HR): 5.74 [95% CI, 2.28 - 14.45]. This study provides models and equations that can be implemented as a scoring system to assist in decision-making by calculating the instantaneous Relative Risk (RR).

Impact of social isolation due to COVID-19 on physical activities practice and sports among schoolchildren in a small city in Rio Grande do Sul

Thu, 16 Oct 2025 00:00:00 +0000

The study analyzes the impact of social isolation during the COVID-19 pandemic on the prevalence of physical activity and the change in the content of physical education classes in Morro Redondo/RS. A self-administered questionnaire was sent to the students, through an online platform, with questions related to two different moments, pre-pandemic (through recall) and during social isolation. It was found that physical activity levels fell from 72.6% to 38.7% during isolation (p <0.001). Favorite sports activities remained the same, however, with a reduction in frequency. Regarding school physical education content, there was a reduction in the use of sports in classes.

Establishing the concept of integrality in health during interprofessional education

Mon, 06 Oct 2025 00:00:00 +0000

The integration of a healthcare team requires professional training that provides tools to stimulate interprofessional practice. Building the ability to work as a team is necessary for the effectiveness of comprehensive healthcare and for sharing knowledge and insights from different areas regarding the healthcare needs of users. The objective of this work is to present and discuss the results achieved during the reflective methodological process of interprofessional learning that occurred in the development of this mandatory course, “Health-Disease Process and Comprehensive Care”, in the professional master's program in Collective Health. The course was planned to follow the methodological strategy of the Maguerez Arch, with observation of reality guided by the question: “What do you understand by comprehensive healthcare?” Mind maps were created before and after the theoretical stage, whose presentations and discussions were analyzed using Bardin's content analysis method. The identified categories were comprehensiveness as a holistic view of the human being, comprehensiveness as public policy, comprehensiveness as individualized care, and humanization as an essential point of comprehensiveness. After theoretical reflection and, based on it, a different perspective on practice, more operational and objective categories were incorporated: professional training, environment, health education, and interprofessional practice.

Políticas e práticas de saúde em enfermagem

Tue, 23 Sep 2025 00:00:00 +0000

From the historical context of nursing education, an expansion of its space in the health area is observed, as it assumes an increasingly decisive and proactive role in identifying the population's care needs. This study proposes to discuss whether nursing plays a leading role in the construction and structuring of women's health policies. It was identified that nursing emerged occupying a supporting role and that it has been modifying its performance longitudinally. In Brazil, with regard to public policies on women's health, they focus on maternal care, still focused on reproductive health and its harms, which partially limits the role of nursing. However, with the creation of the SUS, the nurse becomes a key professional in providing prenatal care, due to his ability to act in health promotion and disease prevention strategies through humanized care, standing out for his technical competence. Finally, it is understood that nursing in advanced practices is a fruitful way to recognize the professional role of nurses by providing quality training and excellence in performance.

Érica Bäringer, Deisi Maria Vargas, Luciane Coutinho de Azevedo — Tue, 07 Oct 2025 00:00:00 +0000

Objective: To evaluate the impact of Supravita, an extension project, on the care of adolescents with obesity. Methods: Retrospective cohort study with 26 participants from the Supravita project. It was evaluated demographic (age and sex), anthropometric (weight, height, BMI, waist circumference and puberal estage), metabolic (fasting glucose, insulin, triglycerides, total cholesterol, HDLc and LDLc, CRP, ferritin, uric acid, TGP and vitamin D) and lifestyle variables (eating habits and physical activity). Data were presented using descriptive statistics with calculation of means, standard deviation and median. In the statistical analysis, the Kolmogorov-Smirnoff, Willcoxon and Student t tests were applied. Results: Most adolescents who remained in follow-up for more than one year reaching the recommended IMC reduction target. There was an increase in the practice of physical activity (162.12 ±88.07 vs. 213.33 ±82.83 minutes/week) and an improvement in the dietary pattern. The number of consultations ranged from 2 to 10, with an average of 4.0±2.2 and a median of 3.0. Conclusion: The treatment strategies used in the project were effective in caring for adolescents with obesity in the context of primary health care.

Débora Fernandes Pinheiro, Vania Schmitt — Tue, 23 Sep 2025 00:00:00 +0000

With the increase in demand for meals outside the home and the growth of overweight people, the study aimed to evaluate the nutritional quality of transportable meals in the municipality of Guarapuava-PR. This is cross-sectional research conducted in three food production units (UPR). Data from three transportable meals were collected, for evaluation and comparison with the norms of the worker's feeding program (PAT) and the qualitative evaluation of the menu preparations (AQPC). It was found that in relation to the caloric value, all were above the recommended. In the macronutrient question only UPR3 was adequate, the others contained high lipid and protein value, occurring carbohydrate deficit. In the qualitative analysis, UPR3 obtained the best results. This emphasizes the need for a nutritionist to elaborate menus in food production units.

Active Methodologies in Teaching Programming Logic

Guilherme da Silva Xavier, D´ébora da Silva Motta Matos — Tue, 23 Sep 2025 00:00:00 +0000

This paper reports the experience of using Active Methodologies in teaching the subject of Logic Programming in a technical course in Computer Science, through the application of an educational product, of the Didactic Sequence type. The research developed the study of teaching strategies in the subject through a differentiated methodology that goes beyond practices focused only on content. The search for new ways to teach Logic Programming is due to the relevance of this curricular component for technical and higher education courses in the area of Information Technology, since it provides basic knowledge for the other contents covered in these courses. In this proposal, the Active Methodologies by Problem Solving and Cooperative Learning with Rotation by Seasons are used. The Didactic Sequence is composed of practical activities for creating and developing algorithms and solving problems with a collaborative format, which aims to provide meaningful learning in students of technical courses in the area of information technology. During the work, the application, acceptance, and contribution to learning the programming logic content was evaluated.

Sun, 12 Oct 2025 00:00:00 +0000

The Computer Networks discipline is crucial in today's era, where connectivity and information exchange are essential. This article aimed to (re)define students' knowledge through active methodologies, developing a Potentially Meaningful Teaching Unit (UEPS) based on Problem-Based Learning. The qualitative case study research involved students from the 4th semester of the Technical Course in Systems Development. A questionnaire was used for data collection, and data analysis followed Yin's (2015) method, comprising five phases: data compilation, disaggregation into smaller fragments (categorized or not), regrouping into categories, interpretation of categories in narrative form, and conclusion. Results indicate that UEPS enriches the discipline, aligning with students' experiences and expectations, better preparing them for practical challenges in the field, and promoting greater engagement and effectiveness in learning.

Study of anthropogenic emissions in the life cycle of Body in White manufactured in new generation steels

Cássio Aurélio Suski, Renan Rosa Ferreira — Wed, 08 Oct 2025 00:00:00 +0000

The objective of this article is to evaluate the life cycle of vehicles with a B-Body developed in new-generation steels (New BIW), compared to currently used steels (Current BIW), aiming to reduce vehicle mass and anthropogenic emissions. The method was based on the estimation of anthropogenic emissions through simulation in the GREET2.7 Module, where the life cycle of vehicles with a Body developed in new-generation steels (New BIW), which have greater mechanical strength, was compared to BIW in currently used steels (Current BIW), which have lower mechanical strength, aiming to reduce vehicle mass and its respective emissions. As a result, a 2.65% reduction in vehicle mass was obtained, which resulted in a reduction of 0.11 tons of greenhouse gases. Just as, in the comparison of simulated emissions, between the current BIW and the new one, there is a reduction in total GHG emissions of 2.8% during the life cycle of the materials, of 3.6% during the life cycle of the Body of vehicles (BIW, interior, exterior and windows), 2.04% over the complete life cycle of vehicles and 0.78 ℓ/100 km of consumption. The conclusions show that the mass reduction of vehicles developed in new generation steels (New BIW) provides a significant change with regard to anthropogenic emissions, mainly in the vehicle use phase, due to the reduction in the burning of fossil fuels and the study provides an important decision-maker regarding the mitigation of global warming, as it is essential to recognize that motor vehicles are significant air polluters.

A qualidade do vinho catarinense

Thu, 02 Oct 2025 00:00:00 +0000

The wine industry transforms grapes into wine and uses different tools for controlling the process and producing wines with quality. The aim of this research was to identify the quality process control used by wineries from Santa Catarina - Brazil, and correlated them with the perception of quality identified by the consumers of catarinense wines. Qualitative research was carried out using an online questionnaire including the free word association technique. The results indicated that the Santa Catarina wineries participating in the research (n=39) preferentially use Good Manufacturing Practices as a quality tool, and more frequently associated words linked to process dimensions (36.36% ) and sensory attributes (26.36%) to define wine quality. For consumers of wine from Santa Catarina, quality was most frequently associated with the dimension of sensory attributes (69.3%) and then with terms related to the product, such as visual identity and product. It is observed that the wine industry and consumers are consistent regarding the importance of sensory aspects in the perception of quality of a wine from Santa Catarina. On the other hand, this study demonstrates important gaps corresponding to wine consumption and production habits in Santa Catarina, as aspects such as quality and sustainability were poorly correlated. Thus, the data from this research will help in the development of the wine sector in Santa Catarina, supporting industries in improving their processes with a focus on the quality and positioning of their products.

Arthur Emmanuel de Medeiros Nóbrega, Antonio Conceição Paranhos Filho — Wed, 01 Oct 2025 00:00:00 +0000

Data in wind geotechnology are very useful for characterizing specific parameters for ventilation. Currently, information is being organized, customized and made available in electronic documentation about the wind. Available on the Internet, values based on overlaps of scales, which use different types of measurement, which are raised in meteorological stations, satellite images and simulations in Computational Fluid Dynamics, are used together to build automatic graphics with a high degree of precision. The work aims to explore resources for obtaining wind data that can serve as a basis for the adequacy of studies in a given environment with known coordinates to characterize winds that allow directing potential for bases of environmental comfort. To describe an exploratory method, the GWA – Global Wind Atlas system, from Danmarks Tekniske Universitet, was selected, which is also being maintained by the Group World Bank, which uses surveys and modeling processes for around 10 years. As a result, data samples were collected that formulated parameters of average speeds, frequency variation and wind directions approximation by specific point locations in modeling environments. In addition to linear graphics and rosette diagrams for specific points on the planet, color maps that encode different speeds are reproduced in the system. For the chosen area of Ladário, Mato Grosso do Sul, a Brazilian city close to Bolivia, rises along the banks of the Paraguay River and is surrounded by massifs, data were collected from two points considered to be at an altitude of 104 and 570 m , for application in the GWA system, at relative heights of 200, 150, 100, 50 and 10 m from the winds, with a thermal discomfort due to the low wind speeds caused by the orographic barriers that present a wedge formation in the Urucum mountain range and the relief of Taquaral.

Nanotechnology is an area of constant expansion, including studies of silver nanoparticles (AgNPs). To obtain them involve chemical processes that can generate toxic waste. This research aims at the use of sustainable technique that aims to use natural extracts as reducing agents and stabilizers, replacing toxic chemical reagents. In the study was used hydroalcoholic extract of Bauhinia forficata L. (BF) and silver nitrate (AgNO3) as precursor agent. The characterization was performed by Visible Ultraviolet Spectroscopy (UV-Vis), pH influence, X-ray diffraction (XRD), ANOVA statistical analysis and bactericidal effect on Staphylococcus aureus - ATCC25923 (S. aureus) and Escherichia coli - ATCC25922 (E. coli). The spectra showed the formation of AgNPs in the characteristic region and considerable stability over time the diffractometer revealed characteristic peaks of the presence of nanoparticles in the samples, and antibacterial activity confirmed by the expressiveness of the inhibition halos. The species S. aureus was the most sensitive strain to nanoparticles, thus showing promising as sustainable bactericidal agents.

Classificação automática de glóbulos brancos com Deep Learning

Mon, 20 Oct 2025 00:00:00 +0000

Blood analysis provides valuable diagnostic information about normal bodily functions and pathological changes. White blood cells are one of the components of blood and are part of the immune response system, responsible for triggering the inflammatory and cellular response to injuries or pathogens. Traditional cell counting techniques used in laboratories are slow and labor-intensive, which can lead to incorrect results due to the need for human intervention in the process. In this study, an automated approach for white blood cell classification is proposed using deep learning methods on a dataset consisting of over 12,000 images. In the conducted tests, the proposed approach achieved an accuracy of approximately 86%.

Utilizando a Computação Tangível como estratégia para facilitar o Ensino e Aprendizagem de Lógica de Programação

Giani Augusto Braga, Anubis Graciela de Moraes Rossetto — Mon, 06 Oct 2025 00:00:00 +0000

As disciplinas iniciais de algoritmos e lógica de programação nos cursos de Computação frequentemente se tornam um desafio para os estudantes. A falta de familiaridade com o pensamento computacional pode ser um fator significativo, levando, em muitos casos, à reprovação ou até mesmo ao abandono do curso. Outro obstáculo é a escassez de acesso a equipamentos, como smartphones ou computadores, para estudos extraclasse. Diante disso, é necessário que os professores adotem metodologias que rompam com o formato de aula tradicional, possibilitando avanços no processo de aprendizagem. Desse modo, o presente texto resulta de um processo de ensino e aprendizagem em que foi desenvolvida e aplicada uma ferramenta educacional tangível em uma turma do curso de Desenvolvedor Mobile: peças de quebra-cabeça impressas em uma impressora 3D para o ensino de algoritmos e lógica de programação. Os resultados demonstram-se promissores, pois mais da metade da turma obteve nota superior a seis, nas avaliações que envolveram esses conhecimentos e aproximadamente 80% demonstraram compreensão dos conceitos básicos de algoritmos após a realização da atividade.

Elaborating a Vehicular Emission Inventory for the Municipality of Pelotas (RS)

Jeferson Peres Gomes, Willian Cézar Nadaleti — Mon, 20 Oct 2025 00:00:00 +0000

This work aimed to elaborate an inventory of vehicular emissions for the municipality of Pelotas (RS). The research followed the bottom-up method of the São Paulo State Environmental Company (CETESB), considering the particular aspects of the city. The study determined the following emissions for 2022: 1341.19 tons of carbon monoxide (CO), 1244.05 tons of nitrogen oxides (NO_x), 307.01 tons of volatile organic compounds (VOC), 37.05 tons of particulate matter (PM), 15.81 tons of sulfur dioxide (SO₂), and, finally, 480.53 Gg of carbon dioxide equivalent (CO₂e). Furthermore, Pelotas has higher per capita emission of pollutants and greenhouse gases compared to some metropolitan regions, including São Paulo. This result suggests that Pelotas’ emissions are intense. However, in contrast to the last inventory, the Pelotas’ emissions have decreased, mainly due to the renovation of the vehicular fleet that occurred in the same period. Therefore, despite the observed improvements, actions must still be taken in order to reduce the intensity of vehicular emissions in Pelotas.

Influence of multiple water uses on an cross-border watershed in South America

Mon, 29 Sep 2025 00:00:00 +0000

Knowing water behavior of water, such as flow and level in a watershed is extremely important to manage its multiple uses adequately. One of the models that has been highlighted by several studies and strategies to diagnose and understand hydrological processes and, consequently, define multiple water uses, is the Large Basin Model (MGB). The Mirim-São Gonçalo watershed (MSGW), which is a cross-border basin that stretches over the extreme south of Brazil and northeastern Uruguay, has significant environmental, economic, political and social importance to the population that lives there. This study aims at applying the distributed MGB to the MSGW to describe hydrodynamic processes and fluctuation resulting from water levels by considering input and output in the system, natural and anthropic ones, based on the Water Exploitation Index (WEI) and the Water Commitment Index (WCI). Results show that the adapted MGB enabled to simulate hydrological-hydrodynamic characteristics in the MSGW when information on winds were inserted. Results of the Brazilian part of the basin were better due to the distribution of input data. Regarding multiple uses, both the WCI and the WEI clearly show that the Uruguayan part of the basin is in a comfortable situation, in contrast with the Brazilian part, which needs special and criterial care since its situation is more critical.

Pathological manifestations caused by humidity

Jeandson Willck Nogueira de Macedo — Tue, 23 Sep 2025 00:00:00 +0000

Moisture is one of the most aggressive agents in buildings, which can generate unscheduled costs and compromise the performance conditions and durability of buildings. Thus, the proper use of the waterproofing system is essential for the prevention of pathological manifestations caused by humidity, which encourages research in order to better understand the influence of humidity on the deterioration of the constituent systems of buildings as well as the main techniques used. to ensure the water tightness of buildings. In this perspective, the present case study aims to carry out a qualitative and quantitative analysis of the main pathological manifestations caused by humidity in a public building located in Natal-RN, with emphasis on the evaluation of symptoms, origins, diagnoses, prognoses, and therapies. The results indicated that the execution and design flaws were responsible for the emergence of more than 80% of the evidenced manifestations, such as stains, mold, bubbles, detachments, fissures, and cracks. The flaws in the rainwater drainage project and the absence of the waterproofing project were decisive for the partial demobilization of the waterproofing system, resulting in the appearance of several points of humidity in the internal area of the building.

Mon, 29 Sep 2025 00:00:00 +0000

The marbles are metamorphic rocks rich in calcium and magnesium with several applications, e.g. cement production, soil PH correction and animal nutrition. Therefore, the present study aims to analyze the application of Matarazzo marble from the Fazenda Brasileira quarry, Arroio Grande, RS, for the animal feed industry. The methodology consisted of a field study of geological controls and the carrying out of chemical analyses on samples of pure and impure marble from Fazenda Brasileira using the Inductively Coupled Plasma Spectrometry Method. The calcium and magnesium content of the samples was measured using national parameters adopted for animal nutrition and compared with data from the Matarazzo quarries, in the same study region, and Mônego, Vila Nova do Sul, RS. Data from the Mônego quarry was used considering that the material is marketed for the purpose of this study. Based on measured data and comparative analysis, pure Matarazzo marble is suitable for use in the animal feed industry, but geological and chemical control is necessary due to the heterogeneity of the material in the studied region.

Luciano Moura de Mello, Simone Erotildes Teleginski Ferraz — Tue, 23 Sep 2025 00:00:00 +0000

Rice is an important brazilian agricultural product, with the Rio Grande do Sul state being the largest national producer, furthermore, agriculture is an activity extremely dependent on climatic conditions. The objective of this work is to show how future climate change scenarios can directly affect rice production capacity in southern Brazil, using maximum entropy mathematical modeling for the prediction of areas favorable to the crop today and in two extreme scenarios, from 2021 to the year 2100. The data reveal that in any future scenario there is a projection of a reduction in productive areas and a fragmentation of these areas, which will require different strategies to face this effect of climate change on rice production in southern Brazil.

Soybean seed production of tolerant or stable cultivars and susceptible or responsive cultivars to phosphorus fertilization

Tue, 23 Sep 2025 00:00:00 +0000

The objective of this work was to identify the responsible mechanisms for the superior performance of soybean seeds produced under high phosphorus availability. Seed production of cultivars DM 66i68 RSF IPRO (more tolerant or more stable) and SYN 15630 IPRO (more sensitive or responsive) was carried out under doses proportional to 0, 50, 100, 150 and 200% of the recommended P for an expectation yield of 5 t ha^-1 of grains. Phosphate fertilization promoted greater seedling growth, increased the yield components, the proportion between total shoot dry matter and grain production, in addition to increasing the concentration of minerals P, Ca, Mg, Fe and Zn. Seeds produced under greater availability of phosphorus present less loss of solutes during imbibition in the tests of electrical conductivity and potassium leaching and produce seedlings with higher rates of emergence speed, dry matter, and leaf area of seedlings.

Production sites at physiological quality of Urochloa decumbens seeds

Thu, 23 Oct 2025 00:00:00 +0000

Obtaining seeds of good physiological quality, is the result of a set of factors related to climatic conditions, mainly temperature and rainfall in the production fields, so that it is one of the main challenges for agricultural production because they influence the seed formation process and, consequently, interfere in its quality. Thus, the aim of this study was to identify which production site, based on temperature and rainfall, provided Urochloa decumbens seeds with better physiological quality. Seeds from 15 production fields allocated in four states were harvested and taken to the seed analysis laboratory, temperature and precipitation informations were obtained from these locations. The tests made were water content, germination, dormant seeds, and tests of vigor: emergence, first count of seedling emergence in sand, seedling length and seedling emergence in the field. Univariate analysis was used to compare the means of treatments by the Scott Knott test, at 5% probability and to discriminate the environmental factors that influenced the quality parameters, multivariate statistical analysis was applied through Principal Component Analysis. The batch of seeds that obtained the best results for physiological quality came from the production field of Cássia dos Coqueiros – SP.

Diego Balestrin, Sebastião Venâncio Martins, Wesley da Silva Fonseca — Mon, 29 Sep 2025 00:00:00 +0000

The objective of this study was to evaluate the floristic composition, phytosociological parameters, and chemical attributes of the soil to assess the efficiency of exclusive natural regeneration for forest restoration in an area after 6 years of bauxite mining. The forest inventory was conducted for all individuals with a Circumference at Breast Height (CBH) ≥ 10 cm, and phytosociological parameters were analyzed using Fitopac 2.1 software. The area showed dominance of early succession species (pioneers and early secondary). The study revealed a low floristic diversity (H’=1.374) as well as equitability (J’=0.48), with the dominance of the genus Vernonanthura. The natural regeneration technique has proven to be efficient in soil coverage and has contributed to the recovery of soil attributes such as organic matter, soil pH, sum of bases, cation exchange capacity, total-N, and an increase in nutrients (K, Ca, Mg, Mn, and Zn). To enhance floristic diversity and expedite the restoration process in this area, we recommend controlling invasive grasses, enriching the area by planting seedlings of native species from more advanced succession stages, and employing nucleation techniques.

Tue, 23 Sep 2025 00:00:00 +0000

The importance to evaluate the final yield of the crop. The objective of this work was to estimate the linear relationships among growth variables, to evaluate groups of shoot and root variables by analyzing canonical correlations and the genetic distance among the three radish cultivars. The experimental design was a randomized block design, organized in a factorial scheme: three (radish cultivars) x seven (collection times of plants 13, 16, 19, 22, 25, 28 and 31 days after sowing), arranged in four replicates. The plants were collected at regular intervals of three days, starting on the thirteenth day after sowing until the end of the growing cycle. The variables analyzed in each collection were: number of leaves, leaf area, transverse and longitudinal diameter, root length, shoot, root and total dry matter. The obtained data were submitted to a joint analysis, and the measured variables were submitted to linear correlation with the significance based on the t test at 1 and 5% of probability, this analysis had the intention of evidencing the trend of linear association for the variables and analysis of canonical correlations. Radish plants with larger leaf area demonstrate lower root development, based on the coefficient of canonical correlation. There were positive correlations among all the analyzed variables, especially the leaf area with dry matter, plant height and leaf number.

JOURNEY OF (NON)HEROES IN PONCIÁ VICÊNCIO, BY CONCEIÇÃO EVARISTO

Ederson de Oliveira Cabral, Daniel Conte, Marcel Fernando da Silva — Sun, 26 Oct 2025 00:00:00 +0000

Aimed at the identity construction of Brazilian black women, we seek to understand, in the book Ponciá Vicêncio (2003), by Conceição Evaristo, whether, as a literary product, a protagonist was constructed that fits Joseph Campbell's theory of the hero's journey. The reflections on Ponciá's identity suggest intersections between the concept of hero as understood in literature, even if displacements and adjustments are necessary when confronted with Campbell's theory, bringing a new perspective to the narrative. Writings by contemporary thinkers are used to create a dialogue for a better understanding of the aspects analyzed in Evaristo's narrative. Therefore, it is seen that not only does the novel unveil the expedient of (non)heroes, who present a trajectory as tireless fighters, but also that the author has built a character capable of engaging with the overlooked subjectivity of millions of women, showing clear contours to the neglected humanities.
