RT Journal Article T1 Mathematics teachers’ specialized knowledge mobilized through problem transformation A1 Montes Navarro, Miguel Ángel A1 Chico, Judit A1 Martín Díaz, Juan Pedro A1 Badillo, Edelmira AB In this study we address two issues related to problem-posing tasks in teacher education: (i) thecharacterization of the specialized knowledge mobilized by prospective teachers when carryingout these tasks and (ii) the identification of the prospective teachers’ pedagogical intentions inmaking adaptations to textbook problems. We asked prospective teachers to outline their suggestionsfor transforming a multiplicative problem so as to “promote the understanding” of theirpotential pupils. We then carried out a content analysis of their responses using the MathematicsTeachers’ Specialized Knowledge model of teachers’ specialized knowledge and identified theirpedagogical intentions by means of the constant comparison method. The results show thatprospective primary teachers mobilized both mathematical and pedagogical content knowledgein their responses to the problem reformulation task. Further, four distinct pedagogical intentionsemerged that drew on different interpretations of the task prompt, and this influenced the type oftransformation the prospective primary teachers suggested and the knowledge they mobilized intheir answers.
