For the year 2024, the option taken by line 3 to collectively and practically investigate the potential of these methodologies was to offer a semester-long course entitled: Active learning methodologies and pedagogical references for co-learning in Natural Sciences. Bringing together primary school teachers and trainee teachers, the aim was to broaden the group’s knowledge base and support them in developing actions that demonstrated the applicability and potential of the proposals in the classroom. As a result, in 2025, the group’s main task will be to develop a broad set of research projects based on the data collected during and after the course. The aim is not only to improve the training proposal itself so that it can be offered again in the future, but also to broaden the understanding of what these methodologies are and how they can be characterised and differentiated: how do they differ from other ways of approaching classroom work? How does contact with such methodologies change teaching practices? How do they make student learning more meaningful? Taking into account the functioning of the Department of Education (SEDUC) and the physical characteristics of schools in São Paulo, what are the difficulties in implementing these proposals in the classroom? What factors favour the incorporation of active learning? What adaptations are made by teachers when they implement these methodologies in their daily activities? What is the potential of mentoring in the implementation of this type of proposal, especially when it comes to addressing interdisciplinary content? The answers to these questions should provide contributions capable of producing effects on the activities of the thematic project, both within and outside the line of research.
