A system and method for educating students such that each student can learn material individually and progress through lessons at the student's own pace. The system can present the student with different versions of each lesson for alternate explanations of the educational concepts taught by the lesson. The system can allow each student to progress to the next lesson only when the system confirms that the student understands the educational concepts taught by the lesson, and can provide additional explanations of any material the student has difficulty understanding.
