As Novas tecnologias e suas contribuições para o ensino de geometria plana na educação agrícola

Abstract

This work presents data from a research that objectived the analysis of the dynamic geometry software Cabri Géomètre II to check if it contributes to improve the learning process of Mathematics for high school students at Instituto Federal do Sertão Pernambucano – Campus Floresta, in a constructivist perspective, basing itself mainly in van Hiele’s theory of geometric level thought development. In order to make possible finding answers to the problem stated in the research as well as reach the proposed objectives, this work was divided into four parts: in the first moment, we had the bibliographic research, in the second step we collected data applying van Hiele’s pre-test. The third stage was developed through works in a computer laboratory using the software Cabri, and in the last phase we applied the pre-test aiming the improvement verification that occurred in van Hiele’s levels, and the semistructured questionnaire that intended to analyze the research conceptions in order to verify the impacts in the learning process after the investigation. When the studies were initiated, all the students involved were in van Hiele’s initial level (visualization) and at the end, it was possible to find that the majority of these students moved on to van Hiele’s levels two (analysis) and three, that we call abstraction. Examining the achieved results and the answers given by the students in the semi-structured questionnaire, it was possible to observe that computerized environments expand our intellectual capacities in a way that communication networks give us different types of information providing a better teaching/learning.
