The point, I think, is that the balance point between theory and practice — the point where theory interests teachers who have five preps a day and a stupid faculty meeting at 3:30 — does not exist at the extreme of theory, where it’s being put.
It seems of late that everyone wants to “just change TPRS a little”. There are probably a lot of reasons for that. Some are genuinely trying to find the optimum blend. Some want to make a name for themselves. Some are probably reacting to the lingering stigma against those four letters. But for whatever reason, people are advocating changing just about everything. No, don’t ask stories, use movies. No, don’t plan what you’re inputting, just wing it. To my mind, while variety in the classroom is great, most of these side roads lead away from some of the basic ideas that make TPRS work: personalization, teaching narrow and deep, spiraling, high amounts of repetitions.
