Abstract

This paper describes the results of a research whose objective was explore the conceptualizations of slope in content taught by high school mathematics teachers, through the class notes of their students' math notebook. For data analysis, the Content Analysis method and the descriptions of the eleven slope conceptualizations reported by other researchers were used as framework. The results indicate that the conceptualization Algebraic Ratio, Trigonometric and Parametric Coefficient were the most promoted by teachers in defining, explaining, exemplifying and proposing activities related to the concept, but these with a procedural emphasis.
