Contribuições do software Geogebra para o aprendizado da geometria segundo a teoria de Van Hiele

Abstract

This research was carried out with seventh grade students of the Elementary School, in a private school in the city of Maringá, Pr. The aims were the elaboration and analysis of activity using the GeoGebra Software, including concepts about triangles and quadrilaterals to answer the question: “How the GeoGebra Software through the use of exploratory – investigative activity can help the 7th grade students to improve in the Van Hiele levels? “ The main idea of the project was the elaboration of the activity that should be developed using a pedagogical mediation related to the use of informatics, more specifically using the GeoGebra Software, as an auxiliary resource and in the Van Hiele model of geometric development. The application of the activity to the students happened in a different way. The first activity was a diagnostic test considering the Van Hiele levels, where each student received a paper with questions and they answered on it. During the second and third activity, the students had the opportunity to explore or do the geometrical constructions, identify their characteristics, suggest observations, think and answer each question. The research is characterized as qualitative and according to the process of data collection, it can also be classified as bibliographic and field research. Initially, we did a bibliographic research to the elaboration of our theoretical referential, as well as a reflection about the importance to integrate the geometry teaching with the information and communication technologies and the implications of a teaching work related to the Van Hiele of geometric thinking with the auxiliary of the GeoGebra Software to the development of the activity. So, we moved to the field research process, when we went to the classroom to apply the homework elaborated to the data collection. Analyzing the results, we noticed that: a significant number of students could do the proposed activity and start the process of construction about the concepts of triangles and quadrilaterals; the students didn´t have problems in use the computers but most of them had difficulties to use the GeoGebra Software in the beginning and because of it, we reformulated our activity to achieve our objectives. So, we conclude that the activity based on the Van Hiele geometric model thinking when applied using the GeoGebra Software can make a positive contribution to the transition from one to other level, as suggest such model.
