Uma proposta para o ensino de geometria analítica através da resolução de problemas e do uso do geogebra
Abstract
The concern with the basic teaching of mathematics have grown
over the past years. The results presented in external evaluations
and even the performance in the classroom have worried experts
in education and our entire society. This study was carried out in
order to seek an improvement in education and show the real sense
of the mathematical concepts. We sought to develop and propose
a didactic sequence that promotes students’ understanding of the
key concepts of analytic geometry covered in high school showing by
solving problems, geometric idea behind each algebraic development
conducted over the activities proposals.
It also sought to combine the technology with the help of Geoge-
bra, the activities that were conventionally worked in the classroom,
providing an extension of the conceptual view by the students. The
didactic sequence and the results presented below were designed and
rigorously applied in the classroom as well as having always been
planned with the goal of transforming the student as the protagonist
of ones own knowledge. So it was presented a proposal based on the
Didactic Engineering which combines the geometric vision with the
algebraic development not letting aside that mathematical concepts
are fundamental to the intellectual development of our students.
