Tom Clark is a life-long teacher of mathematics and science with more than 50 years of classroom and tutoring experience at all levels, from elementary through adult. The concepts for VideoText Interactive began 32 years ago as he and his family discussed the ‘why’ philosophy and what eventually became the production materials of the VideoText Interactive program. He is convinced that everyone has the ability to understand mathematics. His wife Alice, his two children, and his brother and sister have all helped bring this program to homeschoolers everywhere. Now everyone can enjoy the benefits of truly understanding mathematics.
