Use prerequisites to establish scaffolded knowledge by setting simple Concepts as prerequisites to more complex Concepts. This extra structure fills in potential knowledge gaps and allows learners to gradually build upon what they know.

Within Ottolearn, there are two types of prerequisites to choose from—mastery prerequisites and exploration prerequisites

It is important to use prerequisites carefully to get the maximum benefit from scaffolding. OttoLearn uses spaced repetition, which prevents learners from achieving mastery through short-term cramming. Even with daily practice it will take at least a week for a proficient learner to reach mastery level 5. Therefore, if you use too much scaffolding, you can create situations where learners’ progress is artificially delayed.
