(1102) THE INFLUENCE OF TEACHER'S KNOWLEDGE FOR TEACHING MATHEMATICS WITH TECHNOLOGY ON THE IMPLEMENTATION OF INVESTIGATION TASKS

摘要

This study intends to understand the knowledge held by the teacher and its influence on theimplementation of investigation tasks using graphing calculators. The theoretical framework focuseson the professional knowledge and on the graphing calculator, and emphasizes the Knowledge forTeaching Mathematics with Technology (KTMT), a model of teacher's knowledge developed duringthis study. The study adopts a qualitative and interpretative methodological approach, undertaking oneteacher case study. The results of the study suggest that it is the integration between all theknowledge domains into an Integrated Knowledge that seems to be reflected in the teacher's practiceand specifically in the diversity of investigation tasks proposed where the graphing calculator is animportant resource. Thus, the KTMT model appears to be directly related to the practice of theteacher, seeming to include the potential to, through the analysis of teacher practice, identify possibleareas for future professional development.
