This paper focuses on a group of Mathematics teachers-colleagues at the same junior high-school, that use a digital medium for teaching probability. They changed it and designed interventions with it; though their discourse, a debate emerged between them. They followed different approaches in the classroom exploitation of this digital medium, they observed the lessons of one another, and they did not share the same view when they reflected on the classroom observations. Seeking a theoretical perspective that was ‘sensitive’ to the effect of their interaction, we used CHAT (Cultural-Historical Activity Theory) to connect this debate, the diversity of teachers’ reflection on design and teaching, and a possible tension between their actions with a description of their practices.
