Reconstrução de conceitos: uso de disparadores no estudo de funções

Abstract

This paper reports to na experience on teachig the basic pré-calculus concepts to future mathematics teacher on the beginning of their course. The intention was to (re)construct these concepts in a justified manner. In order to do that we propose application problems, called “teaching shootigs”, that could be solved by the own students based on their previous knowledge and were used to introduce new themes. Simultaneously we relate the usage of parallel didactics recourses to favor the student’s interest and participation, such as visits to other science laboratories an libraries, enterviews with other areas professionals, use of computational softwares, concrete materials ad games, oral and visual public expositions etc. Here we explain how the experience was built and grew up inside the classroom as consequence of the diary observations ad from the answers ad mistakes analysis. It had a good result not only because the amount of subjects learned but also because the contribution given to this future teacher apprendiceship, which can help him to be dynamic, creative and interdisciplinarian mathematics teacher.
