This investigation explores the combination of Instrumental Meta-Orchestration (IMO) and the Lesson Study methodology (LS) in teacher training. Under the Theory of Instrumental Orchestration (IO) and the knowledge domains of Ball and colleagues, and of Koehler and Mishra, the knowledge mobilized by mathematics undergraduates from a Brazilian public university was analyzed following a research-action-training design. The results indicate the relevance of combining the IMO and the LS to foster both future teachers’ development on mathematics topics and their knowledge on preparing and implementing an IO.
