There is an ethics here. Every solved exemplar, every model answer, nudges the learner toward a memory of success that is performative. But what if success were less about reproducing a template and more about inhabiting problem spaces? Tuts that prioritize models of thought—how to ask, how to test, how to fail and try again—seed resilience. They teach a student to interrogate a question rather than to decode it mechanically. In the long view, that is durable knowledge.
