Quadro didático inclusivo para alunos com deficiência visual relativo à construção de heredograma

Abstract

Teaching how to answer questions of genetics involving the use of heredograms is a great challenge for teachers in classes where there are blind students. Since, for these students, the genetics teaching is limited to the memorization of concepts, not providing opportunities for the development of skills that enable them to develop these types of questions. In the face of this problem, the present work aimed to create an inclusive didactic framework for the construction of heredograms that enable students with visual impairment to understand genetic issues that involve their construction or analysis, thus promoting their effective inclusion in the teaching-learning process. To build such didactic framework, a wooden plywood was cut in the rectangular shape of 50 cm long, 80 cm wide and 1.6 cm thick. After that, the wood was drilled. The holes were spaced 5 cm apart. Then, wooden pieces were constructed that represent the individuals that will compose the families to be portrayed through the heredogram. Circles of 4 cm in diameter and squares of 4 cm in lateral dimensions were made. Both the circles and the squares are 1.6 cm thick and have holes in the middle to fit the wooden pins. The pins, in turn, have a size of 5 cm and a thickness compatible with the holes. The proposed framework proved to be efficient and represents an inclusive educational resource that is easy to reproduce and use. In addition, it has low cost for its manufacture.
