This brings up the question of what you’re trying to optimize for when teaching; in particular, which segment of the student population are you trying to best teach? If the median, then this strategy will, at best, be useless, at worst, actively harm their learning. If the top percentile, then it may very well produce better outcomes than a more straightforward approach. But it does seem to be the case that there’s a trade-off.
