Resumo: |
This thesis aimed to investigate how an environment of action and reflection that involves the pre-analysis , reflections on the pre-analysis , experimentation with students from Elementary School II , post-analysis and reflections on the post-analysis that is related to a didactic sequence on orthogonal symmetric , interferes in the Mathematics teachers knowledge , in the mentioned level. Nevertheless, this research aimed to answer the following question: how can an environment of action and reflection that is constituted in the times for the Complementary Activities, influence the Mathematics teachers (from Elementary School II) knowledge on orthogonal symmetric? The methodology that was used in this study was based on the presupposition of Didactical Engineering according to Artigue (1995) and on the contributions by Schön (1995; 2000). The theoretical referential had its basis on the Theory of Didactical Situations - Brousseau (1997) - to do a study on the influence of the didactical variables that were chosen in the Math teachers (Elementary School II) procedures and answers, as well as their students , and Margolinas (2002; 2004) to hold an analysis on the teacher s activity, in view of understanding how he/she develops the teaching practice and how it can influence students learning. Yet, the theoretical referential was based in Parzysz Picture of Geometric Paradigms (2001; 2006), in the analysis of the nature of the geometric work that is developed by teachers in the moments of construction and analysis of problem situations, and by students in the moments of interaction with these problems. The studies by Grenier (1988) were used as a reference in order to observe the students conceptions of Elementary School II according to orthogonal symmetric. The analysis of the registers that had been provided by the students made it possible the identification of conceptions that are related to the orthogonal symmetric some of them corroborate with the results from studies done by Grenier (1988); other ones seem to be specific in the group of investigated students. The analysis of registers of Math teachers also showed some concepts about orthogonal symmetric, and these conceptions seem to be related to the way this concept is presented in the course books. During the investigation, teachers had the opportunity to evaluate their own practice and reflected on the teaching methods they were using, to really know if they were working or not with their students. It was noted that an environment of action and reflection that is constituted at school, have influence on Math teachers knowledge, but this influence is limited |
