摘要

本文的目的是比较分析教材中的实践与教师在一阶多项式方程教学实践中的实践,探讨它们之间的一致性关系。本研究基于谢瓦拉提出的人类学教学理论。该方法由定性方法组成,其中我们分析了三位教师的数学和教学组织,并将其与参考书的组织进行了比较。结果表明,教材作者提出的教学实践与教师在课堂上有效教授的教学实践之间存在一定的一致性。教师是越来越复杂的任务、技术和技术的组织者,使课堂变得常规化和问题化。c b ax型一阶多项式方程  是三位老师的共同点,尽管其中两位老师使用的是方程类型2 2 1 1 b x a b x a   .

Praxeologias do Professor: análise comparativa do livro didático no ensino de equações polinomiais do primeiro grau
The aim of this paper was to analyze, comparatively, praxeologies in didactic books and praxeologies carried out by teachers in their teaching practice, concerning the teaching of first-degree polynomial equations, investigating the relations of conformity between them. This study is based on the view of the Anthropological Didactic Theory (ATD), proposed by Yves Chevallard. The methodology consisted of a qualitative approach, in which we analyzed the mathematical and didactic organizations of three teachers, comparing them with those of reference books. The results indicate that there is a certain conformity between the praxeologies proposed by textbooks’ the authors to be taught and the praxeologies effectively taught by the teachers in the classroom. Teachers were the organizers of the tasks, techniques, and technology of increasing complexity, made the routine and problematized in the classroom. The first-degree polynomial equation of the type c b ax   was the common point among the three teachers, although two of them worked with the equation type 2 2 1 1 b x a b x a    .
