Aplicação de sequências didáticas investigativas e a construção de diferentes modelos estruturais no ensino de biologia celular

Abstract

The observation of cells reflects a certain complexity, mainly because they are microscopic.For this reason, their study often becomes fascinating, arousing great interest in students. Inhigh school, according to the National Common Core Curriculum and the curriculum of thestate of Espírito Santo, Cell Biology permeates the thematic axis “Life and Evolution”.However, one of the factors that limits the teaching of Cell Biology is the difficulty or evenimpossibility of teaching practical classes, either due to the lack of a laboratory and/orequipment in the school. According to the School Census carried out in Brazil in 2018 by Inep,only 37.5% of state schools had a science laboratory. Given these observations, the mainobjective of this study is to promote, through investigative teaching, student learning based onthe development of structural models for teaching Cell Biology in Basic Education. Toprepare the models, alternative and recyclable materials were used as a teaching strategy. Thisstudy was carried out at the Governador Lindenberg State Elementary and Secondary School,located in the municipality of Barra de São Francisco-ES. Thirty students of regular highschool were invited to take part in the research. This study showed that through investigativeteaching and the development of structural models, the students were better able to assimilatethe content covered, which contributed to meaningful learning, making the studentsparticipants in the construction of knowledge. Furthermore, the use of structural models canminimize the negative effects of the lack of science laboratories or adequate equipment inschools, providing students with practical experiences.
