O uso de modelos tridimensionais à base de materiais alternativos como estratégia no ensino de divisão celular para alunos de 3° ano do ensino médio

Abstract

This work is about the use of three-dimensional didactic models, constructed with alternative or low cost materials to teach the content of Cell Division - Mitosis and Meiosis - in a class of the 3rd year of High School, of a public school in the countryside of State of Piauí. The research had as objective to investigate if the use of such didactic resource can improve the learning about said content considering the difficulty faced by the students in the understanding of the same when approached only by expository classes with white board and dry-erase marker. Materials such as E.V.A, Styrofoam, glue, scissors and pencil were used for the construction of three-dimensional models of mitosis and meiosis phases. The research is a case study of a qualitative / quantitative approach, with data collection as the systematic observation of the development of the activities developed in the classroom and the application of questionnaires (pre-test and post-test) together to the research subjects. The results obtained evidenced that the use of the didactic models on the Cell Division contributed significantly to the improvement of the students' learning, besides having provided a greater interaction of the same with the topics addressed, thus making the class more dynamic and participatory
