The afternoon starts with a plenary lecture by two winners of the Janet Duffin prize 2019, Miguel Ribeiro and Diana Zakaryan.

Indicators and categories of secondary teachers’ knowledge of rational numbers: a focus on the knowledge of topics.

Recognising teachers’ knowledge as one of the main factors influencing their practices and student learning, we aim to contribute to obtaining a better and deeper understanding of the specificities of teachers’ mathematical knowledge. A case study involving one 8th-grade Chilean mathematics teacher is presented in the context of rational numbers. Using video and audio recordings of classroom practices, questionnaires, and an interview, we sought to characterise, and better understand the content of the Knowledge of Topics from the perspective of the Mathematics Teachers’ Specialized Knowledge (MTSK) theoretical framework. The results reveal some critical aspects that teacher education should focus on, while also identifying lost opportunities and examples of “good” practices, thus contributing to the refinement of the MTSK conceptualisation. The conclusions can be considered in a broader perspective, with implications for teacher education in other contexts.

In this talk we will present and discuss the previous mention research and expand it with some examples of the research we have been developing from the given results focusing on the nature and types of tasks (conceptualisation of tasks) for improving (prospective) teachers’ knowledge of the most problematic situations identified both in students and teachers knowledge. 


The conference includes research presentations and workshops. Some working groups will also take place.

The annual open forum is before lunch.
