Abstract

This paper aimed to present four accessible resources for people with visual impairment (VI) designed for teaching alkane nomenclature. Firstly, a pilot was developed, consisting of a raw cotton fabric cut, measuring 20 x 25 cm. It contained the chemical structure of 3-ethyl-2-methylhexane, with nomenclature, molecular formula in Braille and in uppercase letters. Free embroidery was used to embroider the information with different ledges and textures. We tested the pilot with two students VI, one of them blind and the other one with low vision. Semi-structured interviews guided conversations about: organizing information, chemical structure, Braille and handwriting. The results were analyzed based on the students' evaluation and considering their suggestions, the four accessible resources of alkanes were built: octane, 3-ethyl-2-methylhexane, cyclohexane and 1-ethyl-2methylcyclopentane. We concluded that embroidery was efficient for developing accessible resources, due to its versatility in form edges, which helps to create mental images. And the resources have the potential to improve understanding of the subject.
