Professor of Teacher Education at Butler University. My passions are math education, practitioner inquiry, and equitable and just schooling for all students. Opinions are my own.
Fun surprise to start my day: @kimmontague.bsky.social mentioned my #NCTMATL25 session on the “Math is Figure•out•able” podcast! Can’t wait to work with @pwharris.bsky.social as we continue to convince Kim to join #teampen 😊

One of the most influential mentors I’ve had is @akademic67.bsky.social. Her ideas, her depth of care, her fight, her wit, and-of course-her shoes…all unparalleled and impeccable. Everything she is and does for kids, for teachers, for education is what we should all aspire to be and do. #NCSM25
