Elaboração de materiais didáticos de baixo custo para o ensino de DNA e RNA

Abstract

The Teaching of Biology has been described as teaching based only on the memorization of complex concepts, processes and nomenclatures, which means that students do not feel interested in studying such contents. However, more and more concepts studied in the biology discipline are gaining in the media, and this causes teachers to seek different methodologies só that students do not misinterpret information. To break with this routine of memorization of content Biology teachers are using different teaching materials in their classes, materials that will act as a facilitating agent in the process of teaching learning. Didactic materials, such as practical and field lessons, didactic games, models, didactic models, can work with a tool to break with methodologies based on memorization, but many teachers still find difficulties in using such materials, either at the moment of planning or at the moment the development of the activity. The present research has the objective of developing a low cost didactic model to be used to work the DNA and RNA contents and to evaluate the possibility of this material to be used in the teaching of such contents. A didactic model, proposed consists of pieces that can be embedded, to represent a double strand of DNA, RNA formation and an RNA strand. Through the obtained results, it can be affirmed that the proposed didactic model can act as a facilitating agent in the teaching process of the students, because it places the student as an active agent in this process. The developed model presents an easy handling, besides presenting a low cost to be made, also presenting a good durability, being able to be used several times.
