## Focus on Mathematics, Phase II: Assessing Mathematical Habits of Mind for Teaching

### Description

Focus on Mathematics is a targeted MSP funded by the National Science Foundation since 2003. As part of this work, we are developing a research program with the goal of understanding the connections between secondary teachers mathematical habits of mind (MHoM) and students mathematical understanding and achievement. We are developing tools to study the question: What are the MHoM that high school teachers use in their professional lives and how can we measure them? In this session, we will share our working definition of effective teaching and describe how that definition is shaping the development of an assessment to measure MHoM.
