Proposta de unidade de ensino potencialmente significativa em genética e biotecnologia a partir da análise do desempenho no Enem

Abstract

It’s very usual in the academic field to face great difficulties by the education professionals to the aloofness and, also, the students’ unpreparedness. The Biology teaching faces many difficulties, especially when it comes to public schools. Besides the challenges related to the students, there is also a huge amount of content to be taught within a reduced number of weekly classes available. Other major concern is connected to the resources lacking and also to the difficulties teachers have dealing with complex issues inside and outside the classroom. The present work pursued to analyze the number of correct answers of items in in the field of Natural Sciences related to the Genetics and Biotechnology in the National High School Exam (ENEM) from 2009 through 2017. That way, it was possible to select one of the abilities from the National High School Exam (ENEM) in which the students did not show a good performance to elaborate a Teaching Learning Series (SEA) as a Potentially Meaningful Teaching Unit (UEPS) to work with the selected abilities. Twenty five selected items from genetics and biotechnology encompassed in the exams from 2009 to 2017 are related to the ability 13. The number four competency in the reference matrix of Natural Sciences and Its Technologies was the most frequent among the selected abilities related to those items. It was possible to notice that, in the Biology field, Genetic and Biotechnology is highly frequent, although the percentage of correct answers was very low clearly showing a deficiency in this knowledge field among the students. Time is frequently used as problem to develop these abilities. Here, we propose the development of a UEPS in order to provide greater interaction between students and maximize the use of the time by teachers. Thus, we believe that either, a meaningful learning of content and also to the sense of interpersonal relations may increases the knowledge of new techniques and even technologies in this field.
