iDL's Adaptive Learning system offers students a great deal of freedom to navigate their own path through an online course, but it doesn't simply set students adrift on their own.
Rather, iDL's Adaptive Learning Server provides continuous, intelligent feedback, guiding students into the learning style that's best for them. The system provides “diagnostic quizzes” after each key concept. The purpose of a diagnostic quiz is not to grade, but to confirm that the student understands the concept.

Step 1: System presents content in initial learning style
Step 2: User takes a diagnostic test
Step 3: System analyzes user performance, identifies concept deficiencies and chooses the best learning model
Step 4: System dynamically creates a remedial course tailored to the user
Step 5: The student takes the remedial course, at the end of which is another quiz (randomly generated) If the student still does not get the concept, he or she is returned to another dynamically generated course presented in a different learning style. At the same time the professor is notified that one of her students is having trouble
