mmm this is interesting, so strongly agree, I've felt and seen others feel the real-world cost of wasted effort. I would sometimes get so indignant, witnessing how an institution was allowing the time of the learners to be so poorly spent, when I'd realize retroactively things about my own experience learning. A big piece clicked in my mind when I encountered this piece about 'tacit knowledge': [0] That piece was rattling around my brain when I encountered "Bloom's 2-sigma problem", which I ended up writing a little explainer on, bc it was coming up in conversation often.[1] I was confused by the title at first, until I read the paper (it's short) and realized it could be re-phrased as "[random person]'s two standard deviation problem", or "Dude's 98th percentile problem". The "problem" was "there exists a reliable way to give 98th percentile results to an arbitrary student, it's simply too laborious for mass instruction". this expensive, non-scalable labor was the 'problem' part. Interesting to me, though, was that the 98th percentile result/effect was fully achieved by mastery-based learning and 1:1 tutoring. (dang, expensive, doesn't 'scale well') But one can still sorta drag those principles into your own learning efforts, one can try to see clearly why it's desirable to have those two things and then adjust one's own learning journey accordingly. (I.E. focus on less that isn't just those two things, or Anki SRS) The two interventions made intuitive sense to me, and I eventually tried to approximate both. [2] In that series i'm trying to capture and make visible the pattern seeking behavior of an expert solving a real problem with me following along and following/making visible the decision making/intuition-following that's being done, in a way that you could do the exact same in a practicable way, if so inclined. It happens to be a kind of resource I wish existed for me, years ago. Not an active project of mine right now.
