I have been a student or a teacher my entire life and hold a Ph.D. from Purdue University. I have taught primary, intermediate, junior high, high school, and university graduate school, and was a graduate school clinic director teaching graduate students how to diagnose and remediate educational problems. As a young teacher I created audiotapes and handouts, which duplicated one-on-one tutoring so students could be actively engaged in the learning process. With the advent of personal computers in education, I studied computer programming so I could continue to automate learning and make it more effective.

As a teacher I discovered that the hardest topics to teach were math concepts and math word problems. When I looked at the field, I found no computer software that adequately addressed those issues. I decided this is where I would place my focus.
When I examined reviewed what needed to be done, I concluded that a successful program must:
Solve a problem with pictures;

Later versions of the program brought administrative controls so teachers could assign students to a class, and problems could be assigned simultaneously to all the students. Individual and class statistics were also added.

My students and I have tested every problem over many years. I hope you are as successful with your students as I have been.
