• This research aims to understand which situations created opportunities for prospective Mathematics teachers to develop their knowledge. Following a design-based research with two cycles, data was collected through participant observation, document collection, and individual interviews. The results show that establishing a focus on prospective teachers’ learning created opportunities to develop their knowledge through discussing empirical articles, teaching the planned lessons, and reflecting on students’ learning.
