Combinatória no ensino médio: concentrando o ensino nos objetos de aprendizagem

Abstract

This work approaches the use of Learning Objects (LOs) facing the teaching of Combinatorics and how these objects can help in the learning process of students. Accordingly, the aim of this work is to check that the use of LOs in Math classes promotes a better assimilation of the contents related to Combinatorics, seeking to awaken in the student curiosity and research in this area. Therefore, we opted for an experimental study involving 20 students of the senior year of High School from School João Mattos, located in Fortaleza, Ceará. These students were chosen at random and divided between two groups, experimental and control, with 10 students in each group. For the collect of data, were used, a socioeconomic questionnaire and a multiple choice test about permutation, arrangement and combination. These data were organized and analyzed with the help of Microsoft Office Excel 2010 program. The results show that the group that had a differentiated approach (experimental) obtained a better performance compared to the group that had a traditional approach (control).
