Instructors should absolutely use spaced repetition in their BMF.io courses. It's one of those tricks that really helps stuff stick in your brain. Instead of just dumping info all at once, you go back to it over time , and that makes it way easier to remember. On a platform like BMF.io, it's super easy to throw in some quick review quizzes, flashcards, or little reminders to revisit key points. Plus, it shows students you actually care about them learning, not just ticking boxes. It doesn't take much effort to add, but it can make a big difference. So yeah, if you're making a course, spaced repetition is kind of a no-brainer.
