The Student Model
Most online learning environments are pretty dumb. They typically deliver the same material to each student, and progress them through the same sequence, regardless of where they started from or how well they understand the information offered.
There has been some excellent research in making learning environments responsive to the student by designers of Intelligent Tutoring Systems (ITS) that have been proven to yield significant increases in learning outcomes.
This is done by establishing what is called a "Student Model," which is a internal representation of what the system thinks the student knows or has done. One could think of it as a kind of "virtual grade book," recording what the student has done and how well they know it.
By comparing the current state of the student model to what we ultimately want the student to know or do, the system can suggest directions that are most appropriate for the student to explore next.
The initial state of the student model can be set up by the teacher to start them off at a level that is appropriate to what they think that student will most benefit by. By the same token, the final state can be similarly set according to what the teacher wants the student to achieve.
