Evaluation of a Questionnaire for Studying Teachers’ Beliefs on Their Practice (TBTP)

Abstract

We developed a beliefs questionnaire named TBTP that allows us to investigate the possible influence of not only beliefs about mathematics but also beliefs about students’ math abilities on teachers’ actions in teaching mathematics and problem solving. The purpose of this study is to evaluate its reliability and validity. In this study, 43 teachers responded to the TBTP. The evaluation shows that the TBTP is reliable and valid since the analyses of the data confirm our hypotheses: teachers’ responses show that they differentiate their style of teaching because of their students’ math abilities and there is a correlation between teachers’ beliefs about mathematics and their responses about their practice of mathematics and problem-solving.
