Percepções de alunos do ensino médio quanto aos conceitos fundamentais da genética básica: um estudo de caso

Abstract

Although it is known the importance that permeates the genetics of learning for academic and personal life of each student, this study sought to know, through the case study, if students are aware of such relevance. Therefore, the scientific problem investigated aimed to know the perceptions of the fundamental concepts of genetics for high school students. He sought to understand what the difficulties pointed out by them in learning this content and also provide a learning strategy that overcomes the traditional teaching and facilitating the study of the basic concepts in genetics. The research was developed at a school teaching the public network in the city of Manaus / AM with students from two classes of second year of high school. The information was obtained through direct observation and participant questionnaires and interviews. These data were analyzed qualitatively according to the guidelines of discursive textual analysis. The findings show that often the teaching addressed in the classroom material only by memorizing concepts, thus losing the context of the concepts and without clarifying that genetics is a science that involves the everyday life of each individual. It was noted that students have the perception that genetics is too hard to understand it, because of the large vocabulary surrounding the matter, do not see sense in studying the subject, except to get approval in the vestibular and are therefore uninterested in most cases. One of the possibilities for change in this situation is the dialogue-based lecture which is a strategy that has been suggested to overcome the traditional teaching, to promote the participation and involvement of students on the above subject.
