I don’t think “throw every explanation possible” is the right takeaway from your experience. To me, it seems like the teacher was failing to model what you were getting stuck on, and so the takeaway would be something more like “try to model the learner better, so as to produce better (not more!) explanations”.
“Throw every explanation possible” might still be learning-complete in some sense, so might be worth exploring.
