A geometria analítica como conteúdo do ensino secundário: análise de livros didáticos utilizados entre a reforma Capanema e o MMM

Abstract

This study aimed to produce a historical study of the trajectory of analytic geometry and content of mathematics in secondary education, in the period between 1940 and 1970. In this research, the time frame was restricted to the period in which the Reformation were in effect Capanema, the Ministerial Decree of 1951, and a movement of international dimension named Modern Mathematics Movement (MMM). The research, part of the field of the history of mathematics education, took the textbooks of this discipline to the college as a research resource. To analyze the changes that have occurred historically in textbooks regarding, the content of analytical geometry, this historical work was supported in theoretical assumptions of historians and historians of education to discuss the cultural history, the school culture, school subjects and textbooks as objects historical, notions of ownership, strategies and tactics. The analysis revealed similar works and books converged with both programs in the 1940s as in 1950. Specifically in relation to analytic geometry in 1940, this constituted one of the blocks that made up the mathematical school, even as a legacy of mathematics fragmented into branches of the previous decades. In the 1950s, analytic geometry stopped appearing explicitly and was diluted by the study of limits and derivatives, and restricted to the study of the line and the circle. Analytic geometry has gained momentum again with the advent of the MMM. However, there was no standardization observed in previous decades, it seems the lack of official guidance.
