I have given presentations at local, state, and national mathematics education conferences (some requiring peerreviewed proposal submissions and some by invitation). The topics include the NCTM Standards, the California Mathematics Framework, curriculum guidelines in the 50 states, the role of technology in school mathematics, implications of educational research for the classroom teacher, probability & statistics in secondary school mathematics, finite geometries, and active learning during lecture. I've also given numerous in-service workshops for teachers.
