I have a Ph.D. in the Psychology of Learning from the University of California, San Diego and over 25 years of experience in creating computer-based instructional materials. Since 1989, I have started and sold two companies, Computaught, Inc, and iLearn, Inc., with a focus on math education in grades K-8. In 2024, I launched Math inSight, Inc., with a focus on Early Numeracy and Number Sense in grades K-2. At Math inSight, we are laser focused on improving student outcomes and reducing teacher workload.
