Theoretically and Practically Speaking, What is Needed in Diversity and Equity in Science Teaching and Learning?

This article discusses how issues of diversity and equity are addressed in the preparation of science teachers who are charged with teaching diverse students in schools. Highlighting examples from my own teaching and research and other studies in education, I frame this article in terms of a broad application of theory in science teacher preparation to classroom practices in order to address science achievement and equity for diverse students. I also discuss the relevance of my argument for in-service professional development.
