I can help you with your professional development program for mathematics teachers.
I have offered professional development workshops for teachers (since preparing IMP teachers 1995-8) as well as sessions for support personnel (CMP, 2003). I can also help you present sessions for parents, administrators, and college students considering teaching. I can work in person or online.
A few sessions that are ready to go:
    Pros and cons of "reform" mathematics curricula
    Improve your students' test scores by teaching multiple approaches
    The Perry Scheme and college mathematics
    On beyond problem solving
    The mathematics of contra dancing
Or let me design one to meet your needs.
May I help you? Contact me.
