A Construção de modelos didáticos de células sanguíneas por alunos do ensino médio/Técnico: criar para aprender

Abstract

This essay seeks to describe the research done on the use of didactic models of blood cells within the teaching process and to analyze how students build these models from observations made in the science laboratory. This process was mediated by the Biology teacher Cláudia Girundi and me, Poliana Alves de Barros (school lab technician or school lan manager) and the learning was presented to the school community at a science fair. The students are freshmen of a private vocation school and have buit new practices, which have broken with the traditional teaching observed by memorizing the textbook contents. This research methodology started with the practical class in laboratories, followed by research on blood cells. After this first approach, the students were encouraged to build didactic models that culminated with presentations in the classrrom and at the researched schools Science Fair. These studies indicate that the construction of didactic models through investigative activity is relevant and results in significant learning. It was possible to associate practical classes, theory, didactic models and presentation to the community as a way to show these actions can go together.
