Desenvolvimento de modelos de interações intermoleculares e de um recurso didático para as aulas de química

Abstract

The traditional approach of education, historically adopted by the Brazilian school class, fails when thought by the piagetian conception of cognitive development of the person. The regular education found in Brazil is characterized by the transmission and accumulation of information, constantly evaluated, focused on totality of subject proposed. In the discipline of chemistry, intermolecular interactions depends only on the abstraction to be understood. This work focus on the development of intermolecular interactions models, based in atom/interaction system, with styrofoam spheres/magnets, that simulate this situations allied a dynamic didactic resource and work‟s evaluation, with exams and perceptions. The proofs, similar in difficulty and equal in number of questions, were applied before and after the execution of proposed work and the perceptions of author and an invited academic were compared. The use of this feature, when compared by an exam to traditional class, increased 27.78% the average grade of students.
