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

Juliana Fraga — 2025-09-23

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.

The The game as element of cultural heritage mediation

Dorcas Weber — 2025-09-23

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.

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

Sylmara Castro Vianna — 2025-09-23

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.

Between Memories and Resistance:

Nathalia Vieira Ribeiro — 2025-09-23

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.

Scientific Initiation

Bruna Bertoglio Lorenzoni — 2025-10-01

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.

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

Francisco José da Costa Costa — 2025-09-23

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.

Active Methodologies in Object Oriented Programming Learning

Fábio Aiub Sperotto — 2025-09-30

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.

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 — 2025-09-23

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.

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

Alice Beatriz Assmann — 2025-09-27

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.

New Sociabilities, networks, and technology

Cyntia Barbosa Oliveira — 2025-09-25

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.

COVID-19 AND POST-GRADUATE PANDEMICS

Francisco das Chagas Silva Souza — 2025-09-25

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.

Guidelines for Community Outreach Programs in Brazilian Higher Education

Ronaldo César Darós — 2025-09-30

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.

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

Lara Ronise de Negreiros Pinto Scipião — 2025-09-29

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.

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.

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

Marcio Watanabe — 2025-09-23

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.

Technological action in basic education as an incentive for female empowerment

Andressa Soares Bento — 2025-10-05

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.

Renata Porcher Scherer — 2025-09-23

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.

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

Tayná Laureth — 2025-10-01

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.

Predictors of suicidal ideation in university health area students

Ana Paula de Oliveira — 2025-09-23

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.

Environmental education in the field

Sindineia Rosa de Oliveira — 2025-10-02

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.

STORYTELLING

Pâmela Cibeli Klug Gauber — 2025-09-29

This work presents a research carried out with the objective of understanding the impact of Storytelling as an educational strategy in the context of the Administrative Assistant course, industrial learning modality, taught at the Professional Training Center SENAI Porto Alegre. The methodology adopted included an exploratory narrative literature review, followed by a data collection survey to explore the connections between theory and practice. Twenty-six students participated in the experiment, which consisted of developing a project, but with two different approaches: one focused on essentially technical-based guidance and the other applying Storytelling methods. Students' engagement and motivation were analyzed as indicators of the effectiveness of the educational strategy.

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

Cristina Novikoff — 2025-09-25

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.

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

Simone Aparecida Rigobeli Vanalli — 2025-09-23

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.

Plural Representations of Youthful Masculinities:

Mauricio Nazarete Lopes — 2025-09-23

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.

Educação Estética e Modelagem no Ensino de Ciências

Paola Cazzanelli — 2025-09-23

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.

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

Dilson Ferreira Ribeiro — 2025-09-29

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.

Bússola na Trilha Certa

Cássio Aurélio Suski — 2025-09-23

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.

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

Denise Ana Augusta dos Santos Oliveira — 2025-10-06

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.

External assessments

Carla Vargas Bozzato — 2025-09-30

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.

Estresse e resiliência em uma universidade pública

Fernanda Fátima Cofferri — 2025-10-01

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.

Emerson de Souza Queiroz — 2025-09-23

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.

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

Gleicy Kelly Felix Costa — 2025-09-23

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.

Políticas e práticas de saúde em enfermagem

Angélica de Godoy Torres Lima — 2025-09-23

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.

Débora Fernandes Pinheiro — 2025-09-23

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.

Establishing the concept of integrality in health during interprofessional education

Etienne Alessandra Hafemann — 2025-10-06

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.

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

Giani Augusto Braga — 2025-10-06

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.

Dados em geotecnologia eólica

Arthur Emmanuel de Medeiros Nóbrega — 2025-10-01

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.

A qualidade do vinho catarinense

Luindson da Cruz de Carvalho — 2025-10-02

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.

Foram realizadas avaliações de biométricas (altura da cana, diâmetro do colmo e quantidade de perfilho), além da pesagem e da análise laboratorial (POL, fibra, TPH e ATR). Os resultados mostram que os genótipos GRB10 e GRB11 apresentaram bom desempenho, demonstrando grande potencialidade paras as condições de estudo.

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

Gustavo Zimmer — 2025-09-23

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.

Modeling of rice production areas in southern Brazil, under extreme climate scenarios

Luciano Moura de Mello — 2025-09-23

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.

Canonical correlations for radish (Raphanus sativus l.) Growth variables

Tiago Pedó — 2025-09-23

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.

Natural regeneration as a technique for restoring an area after bauxite mining, Minas Gerais, Southeast Brazil

Diego Balestrin — 2025-09-29

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.

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

Lukas dos Santos Boeira — 2025-09-29

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 — 2025-09-23

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.

Chemical analysis of Matarazzo marble from Arroio Grande (RS) for use in the animal feed industry

Emanuélle Soares Cardozo — 2025-09-29

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.
