How does confidence selection impact mastery level?
Our goal is to get the learner to true mastery — accurate, fast, and with self-assessed “high” confidence.
There is a “cost” associated with confidence selection that rewards learners by moving them up a mastery level when they are both confident and proficient, and moves them down when they are not.
By proficiency, we are referring not just to accuracy, but also whether the learner responded within a certain duration and met other criteria.
The effect of confidence selection varies, depending on the learner's current mastery level on a Concept.
The image below shows how a learner’s mastery level is affected by a combination of their proficiency and confidence when they are at or below the mastery goal for a Concept:
When learners are above the mastery goal for a Concept, they will drop 1 mastery level if they answer correctly with low confidence.
