Construção de sólidos geométricos com material concreto: experiência de uma turma do 3º ano do Ensino médio

Abstract

This work is based on the application of experimental classes held with a 3rd grade high school class from a public school located in the city of Caxias do Sul in the state of Rio Grande do Sul. This research is qualitative and aims to study spatial geometry through the elaboration of geometric solids using concrete material. In addition, there is also the purpose of reinforcing content studied in basic and fundamental education, such as flat geometric figures. It is also expected that the students will conclude the experience by being able to classify geometric solids, understand their properties and characteristics, and distinguish between polyhedra and round figures. Afterwards, the student responses to the proposed class will be analyzed. The experience is justified because the elaboration of geometric solids with concrete material, combined with adequate theoretical knowledge, makes comprehension more accessible, solidifies the students' learning in geometry, and has the potential to make classes more interesting. Additionally, the research poses the question: what experience can a high school class acquire by elaborating their own geometric solids with concrete material for use as a challenging learning tool? The research demonstrated immediate results, such as increased interest, creativity, and participation, as well as long-term effects, such as an increase in the average grades of the participating students. Moreover, the students who participated in the experience showed more autonomy, interest, and freedom to suggest ideas for more dynamic math classes.
