This document describes a model for supporting collaborative teacher research that was developed and tested over three years. The model includes components like motivation, a learning community, use of data like videos and student work, dedicated time for research, and a structured process using problem-based learning. Teachers found elements like pursuing their own research questions, peer support, facilitator guidance, and extended time to be most useful for improving their practice through inquiry. The model provides an example of effective professional development centered around teacher research.
