I have a way cool family who are scattered all over the world.
I play the guitar, sometimes along with Kari, who plays the oboe.
Until recently, I served on the Board of Directors of Circle Pines Center, a co-operative summer camp and retreat center in southwestern Michigan where Kari and I met many years ago.
I have been teaching high school mathematics and computer science since 1990. During this time, I have focused on the integration of computer technology and symbolic manipulators into the high school curriculum. A number of the resources I use or have developed are publicly available.
I have been a presenter at various mathematics education conferences. You can find here links to materials from the presentations. The links below take you to conference sites.
My C.V. contains a partial listing of conferences, papers, and the like.
