About Visilearn

People

Visilearn CEO Chris Charuhas, a former computer instructor, taught hundreds of computer classes to thousands of students.

Before she retired from the U.S. Department of Labor, Editor Judy Blair ran its computer training department.

Visilearn authors are computer teachers. For example, the tutorials on OpenOffice.org were written by Kevin Jordan, who taught computer classes for Whitley County Schools in Indiana.

Principles

Our primary goal is to help time-pressed teachers. We want to make life easier for teachers, with tutorials that eliminate the need for long lesson plans.

We're also committed to providing tutorials at affordable prices. Textbooks cost too much, so we try to price Visilearn tutorials at around one-tenth of what publishing conglomerates charge for their texts.

History

When Visilearn began selling illustration-based computer learning materials in 2001, customers with learning disabilities told us that our materials were the only ones they could use.

We told the U.S. Department of Education about this, and some people there were intrigued. They commissioned a study on how illustration-based learning materials might help LD and ELL students.

Visilearn conducted research to find out what sort of materials worked best for students with learning disabilities and low English proficiency. Then we created a series of tutorials based on that research.

When the tutorials were tested, they made it easier for special needs students to learn computers, and also worked well for mainstream students. Now we license these tutorials to schools all over the world.
