A big part of a child's success in school has to do with parental involvement. Home schooled children, almost by definition, have highly involved parents. It would be interesting to compare home schooled children with regular children whose parents are actively involved in their education to see how that matched up.

Traditional schools are built on an industrial batch model where the goal is to get a certain percentage of the class to basic competency. So students are grouped in classes, taught for a semester, graded, and then moved on.

The Khan and homeschool model, in contrast is the mastery model. Students are individually taught at their own pace. They are not graded and pushed on. Instead they keep learning a topic until they know it. In traditional classroom education, the learning is variable while the time to learn is constant. Khan makes the learning constant and varies the time. Some students will learn faster than others, but all students learn to a high standard.

Khan is not just delivering a better classroom. He is offering a wholly different model of education.
