David got his PhD at the University of Washington and continues to collaborate with the team as he extends the work of developing and testing tools, courses, and professional development opportunities in Michigan. Currently, David has three overlapping areas of research interests anchored around ambitious teaching practice. First, he frames classrooms as science practice communities. Using lenses from Science, Technology, and Society (STS) and the History and Philosophy of Science (HPS), he examines how teachers and students negotiate power, knowledge, and epistemic agency. Second, he examines how beginning teachers learn from practice in and across their varied contexts. Third, he studies how teacher preparation programs can provide support and opportunities for beginning teachers to learn from practice.
