Current progress and boundaries
Adaptive practice and AI tutoring products are becoming more common, but optimizing short-term performance on practice questions does not necessarily improve long-term learning.
Why it remains difficult
Students may guess correctly or be misjudged because of how they express an answer. Excessive hints can weaken independent thinking, and learning data involves minors? privacy.
Paths worth exploring
Design hints that gradually fade and include reflection questions. Let teachers see why an exercise is recommended, change the learning path, and set rules against giving answers directly.
How to evaluate success
Use delayed tests, transfer questions, the quality of help-seeking, and teacher observations to assess learning. Check by prior skill level whether gaps between groups are widening.
