Professional development is considered a vehicle to assist in developing teacher capacities; one approach for supporting teachers is through practice-based professional development where teachers engage in activities central to their daily work of teaching. In this paper we present the results of a qualitative study investigating how teachers build mathematical and pedagogical knowledge by adapting design experiments to a professional development context. Through the use of case studies we examine if primary teachers can, and to what extent, engage in experiments in teaching, an iterative cycle of three main components: conjecture (posing questions and making conjectures about teaching or learning), implementation (teaching episodes are planned and taught), and analysis which guides the next teaching episode as a intentional method for improving teaching and increasing student learning. In addition, we describe factors that either hinder or promote teachers ability to partake in this in iterative cycle of designing, teaching, reflecting, and redesign of lessons and teaching.
