Questions this source addresses
- How does the timing of practice change what we remember?
- When does mixing different kinds of practice help us learn?
- When should an intelligent tutor make learning harder?
- Why do some things we learn stay with us?
- How can a computational framework for modeling memory decay and retrieval probability be used to derive optimal spaced repetition schedules rather than relying on hand-tuned heuristics?
- How did this data-driven approach to spaced repetition influence the design of later schedulers such as FSRS that have been adopted in tools like Anki?
- In what ways do adaptive spacing algorithms that track individual item difficulty and learner ability outperform fixed-interval systems like SM-2?
- What tradeoff between reviewing items on the verge of being forgotten and introducing new material characterizes an optimal spaced repetition policy?
