Introdução à química para o sistema modular de ensino (some) na região marajoara

Abstract

It is a research about the possibility of using teaching strategies with an eminently constructivist approach to teach basic concepts of chemistry in high school classes of the Modular System of Teaching-MST in the riverside region of Marajó and, after analyzing the results of some didactic interventions that was propose from these ideas, we will present a didactic product with such didactic suggestions. Initially we discuss the influence of the constructivist approach in teaching and learning in the last decades, as well as the historic route of the chemistry teaching in Brazil since the time of the Brazilian colony. Next, we present a characterization of constructivist didactic strategies, such as Predict, Observe and Explain, from its origin, in the researches about alternative conceptions realized in the decade of 1980, until some didactic research related to these and other strategies fulfilled in Brazil. Two didactic interventions were develop to evaluate the relevance of teaching strategies it were proposal. In the first one were detected some technical problems that were tried to heal in the second didactic intervention realized. The results obtained in the second intervention were quite satisfactory, because the students developed the activities in a more enthusiastic way and they went beyond when the students were able to relat the concepts studied with the riverside context in which they are inserted.
