What roles will you establish? You want to build expectation of time investment. If I invest my time in you, how are you going to invest in someone else?
Math behind health insurance. Interesting video that could be applied to math (probability, ratios, etc.) or social studies (government spending, incentives, role of government)
Such tactics certainly work better than raw rehearsal. But they don't solve the underlying problem: They still bypass real conceptual learning. Memorizing a list of prepositions isn't half as useful as knowing what role a preposition plays in the language.
""What's the sine of π/2?" I asked my first-ever trigonometry class.
"One!" they replied in unison. "We learned that last year."
So I skipped ahead, later to realize that they didn't really know what "sine" even meant. They'd simply memorized that fact. To them, math wasn't a process of logical discovery and thoughtful exploration. It was a call-and-response game. Trigonometry was just a collection of non-rhyming lyrics to the lamest sing-along ever.
Some things are worth memorizing--addresses, PINs, your parents' birthdays. The sine of π/2 is not among them. It's a fact that matters only insofar as it connects to other ideas. To learn it in isolation is like learning the sentence "Hamlet kills Claudius" without the faintest idea of who either gentleman is--or, for what matter, of what "kill" means. Memorization is a frontage road: It runs parallel to the best parts of learning, never intersecting. It's a detour around all the action, a way of knowing without learning, of answering without understanding."
