Was a pioneer in Computer Assisted Instruction, 1976-1978. Developed PLATO computer-assisted instruction when teaching at Kennedy-King college. PLATO was an NSF-funded project developed at the University of Illinois. The hardware consisted of hundreds of remote terminals connected to a large CDC mainframe computer. PLATO supported the creations of lessons via programming in the TUTOR language. Monochromatic graphics were available, including animation.
Wrote Basic College Mathematics: A Calculator Approach (with E. E. Robinson), published by Addison-Wesley in 1980. This was one of the first texts to use the scientific calculator as a tool to teach the basic concepts of mathematics. It was adopted at Ohio State University, and used there to teach Freshman who lacked the skills to take the standard pre-calculus course.
Designed and built a hydrostatic equation solver, to illustrate the following principles:
A description of my project was published in the June 1985 "Computer Recreations" column of Scientific American.
