Abstract
Based on the results of research on teacher education, the present study aimed to investigate and mapping teachers’ mathematical knowledge when they think about and they prepare their classes about equation. We take as theoretical framework the results of researches from Ball and her colleagues, in particular, the concepts of "knowledge of content and students" and "knowledge of content and teaching". From a methodological point of view, we have developed a qualitative-interpretive research involving a group of six teachers. Among the results we identified elements of the "knowledge of equation and students", as the difficulty of students to characterize the concept of the equation, as well as elements of the "knowledge of equation and teaching" as the appreciation of the context in the moment to prepare teaching activities of the equation. This study ratifies the relevance of investigating teachers involved in their own practice, particularly at the moment of preparation of their classes.References
