| Sharon Dugdale & Don Cohen |
I've been amiss in not sharing earlier the passing of two wonderful educators (
here and
here) both of whom were influential in my thinking about teaching math (
Don) and using technology (Sharon) to empower my students. In the 1970's both Sharon and Don worked with Plato an early prototype of a computer-assisted instruction system that ran educational software. Don shared an example of software that was a part of the
Madison Math curriculum with me at a conference in 1977. Sharon worked earlier on the Plato system to develop a fractions curriculum (including
Darts and
Green Globs - 2 of my all time favorites) which are still available today. Don went on to work with students (ages 3 to 73) for 38 years teaching them a variety of math topics including Calculus for 4th graders. My condolences to both their families.
