How do I teach these methods without extra class time?
Model one technique briefly, then assign it in place of a traditional review worksheet.
Is cramming ever okay?
It's better than nothing, but it produces much weaker long-term retention than spaced review.
Do younger students benefit from these techniques too?
Yes, in simplified forms, like flashcards and saying answers aloud before checking.
How far in advance should spaced review start?
Starting a week out with short sessions works better than starting the night before.
What’s the single best study technique to start with?
Self-quizzing, actively testing recall instead of rereading, has some of the strongest evidence behind it.
