This paper reports on the second phase of a joint teacher/researcher project that explored teachers’ understandings of the potential of the interactive whiteboard (IWB) as a tool for primary school children’s collaborative group work. By examining teachers’ written analyses and discussions of work carried out in their own classrooms, the paper seeks to contribute to the debate about the ways in which the use of IWBs can contribute to changes in pedagogy. It highlights the interrelationships between collaborative learning and factors identified as important in the research carried out by teachers, amongst them the children’s technical skills and confidence, the mediating role of the teacher, the IWB affordances for knowledge‐building and the teachers’ own knowledge, attitudes and professional development. The paper also provides an account of how participation by the teachers in a course with Faculty staff, focused on the collaborative co‐construction of knowledge related to learning and to classroom research grounded in the values and principles of socio‐cultural theory, supported changes in pedagogic practice.
