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.
Square with four quadrants. Along the left axis is "Knowledge" from low (bottom) to high (top). Along the bottom axis is "Confidence" from low (left) to high (right). The top-left quadrant reads "Doubt (Hesitation)". The top-right quadrant reads "Mastery (Smart Action)". The bottom-right quadrant reads "Misinformed (Mistakes)". The bottom-left quadrant reads "Uninformed (Indecision)".


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:

Diagram showing "proficiency" and "confidence". When proficiency is sufficient and confidence is low, the learner's mastery level does not change. When proficiency is sufficient and confidence is high, the learner's mastery level increases by one. When proficiency is insufficient and confidence is low, the learner's mastery level drops by one. When proficiency is insufficient and confidence is high, the learner's mastery level drops to zero.


When learners are above the mastery goal for a Concept, they will drop 1 mastery level if they answer correctly with low confidence.
