Collaborative feedback or reflections are professional development meetings in which trainee teachers enrolled in EDU 673 Mathematics Education II observe and discuss recordings or pictures from talking with their pupils. This present an example of collaborative reflection based on Lesson Study between trainee teacher and other trainee teachers who imitate to participate as Primary school mathematics learners. Investigating the case knowledge participants? construct in Lesson Study can further our understanding of how trainee teachers interact to influence one another?s learning. This paper will also discuss how participants make inferences about the events they noticed and how they use pictures and videos as evidence for their interpretations
