I have taught secondary mathematics for 37 years and have been using
computers extensively in my work since the early 80's when I got my first
Apple II computer. I have been involved in a variety of NSF projects, all
of which focused on how the computer can enhance the teaching and learning
of mathematics. These projects focused on mathematical modeling, the study
of fractals and chaos and, most recently, on what a curriculum would look
like if computer algebra systems and geometric construction programs such
as Sketchpad were used extensively.
My current interest is in how
computers can be used to teach geometry. I have developed a variety of
materials on polyhedra and how they can be integrated into the secondary
curriculum using GSP, Poly, and Kaleidotile. I have two projects in mind.
First, the development of materials for teaching a vector geometry course
which uses both GSP and Mathematica. The second is developing materials
focusing on 3D geometry using Sketchup, a very easy to use architectural
tool. My real love is geometry, and I would be interested in working on
any geometry related project.
