Práticas aplicadas no ensino de genética para alunos da EJA (Educação de Jovens e Adultos)

Abstract

Genetics, from the discovery of DNA and the Genome Project, brought innovations on a daily basis, becoming an emphasis on magazines and media of researchers who seek updates for the development of Biology, especially when referring to the teaching- learning process. The aim of the present study was to verify whether practical classes are effective tools for consolidating learning in Genetics in learning about DNA, comparing human and monkey karyotypes, Mendel's Laws and the Blood System; for students of Youth and Adult Education (EJA). The study was developed in a public school in Timon-MA in 2019, in three classes of second stage of EJA. Practical classes were used parallel to the contents covered to help in the construction of knowledge and later use of these in the daily lives of school students to improve the Genetics classes for this modality. For the diagnosis, evaluative questionnaires were used before and after the practical classes with similar questions of degree of learning for the subjects approached and of easy characterization of the contents. Subsequently, a manual of practical classes was prepared with explanations of the activities that were developed during this research and intended for use in practical activities for EJA students. The results of this research proved that the applied methodology was guiding for the scientific growth of EJA students, as it demonstrated an improvement in knowledge throughout the evaluative questionnaires applied before and after practical classes, as well as also made it clear that the use of practical classes for this modality it is extremely important. It is noticed that, when working on some subjects of Genetics associated with these practical classes, students were able to associate the acquired knowledge with their daily lives and dazzle the shapes and structures of molecules such as DNA, comparison of karyotypes of humans and monkeys, as well as also Mendel's Laws and the ABO system.
