Trajetórias hipotéticas de aprendizagem relacionadas às razões e às funções trigonométricas, visando uma perspectiva construtivista

Abstract

This dissertation is part of the research project developed by researchers at the Pontifícia Universidade Católica of Sao Paulo, which seeks to develop support materials and curricular innovations to school, taking reference to the notion of Hypothetical Learning Trajectories (THA), a concept used by Dr Simon (1995) as part of the 'model' Cycle of Teaching and Learning of Mathematics. The objective of this research is to analyze the possibility of reconciling perspectives of learning by teaching plans related to the reasons and trigonometric functions and verify the performance of a mathematics teacher in front of a proposal aimed at teaching a constructivist perspective. To answer our questions we developed a qualitative study, collecting data through contents the observation of lessons with teachers and students from three different groups of 2nd year high school public school Education of the State of Sao Paulo. The results indicate that: it is possible to reconcile learning perspective with the planning of education and how important the work of mathematics teacher for learning to occur. We conclude that not just one good result of education, interaction and participation among students and teachers are the main instruments to be made effective a significant learning in a constructivist perspective
