About marcreif

I live and teach high school physics in the town I was born in, Fayetteville, Arkansas. My professional interests include modeling instruction and Advanced Placement courses. I also work as a College Board Workshop Consultant, which means I lead Pre-AP and AP Science Teacher workshops. Lately I've also been leading a fair amount of student review sessions for the National Math and Science Initiative. I have a website for students (fysicsfool.info) and another for AP Summer Institute participants (apsifool.info). I tweet infrequently (@marcreif).
