You've helped them one at a time. The real understanding is how the ideas CONNECT — teach that next.
Spacing Wren (spaced review (WHEN it comes back)) ×Recall Remy (retrieval practice (close the book and recall))
Wren decides when a topic comes back; Remy closes the book and recalls it. Why are they stronger together?
Spacing Wren then says: “Spacing works best if I just RE-READ the topic each time it comes back.” — is that right?
The link: spacing is the calendar, retrieval is the act — do them together and memory sticks.
Bring it back at the right time — then recall it, don't reread it.
Edge Goldi (edge of competence (just-right difficulty)) ×Mistake Mabel (mistakes as information)
Goldi keeps you at the just-right level; Mabel says mistakes are information. How do they feed each other?
Edge Goldi then says: “To learn fastest I should pick problems I already get right — no mistakes means I've mastered it.” — is that right?
The link: the right difficulty CREATES the informative mistakes — and the mistakes tell you you're at the right difficulty.
A few good mistakes mean you're standing exactly on the edge.
Capstone — plan a week of study for a hard topic
You have a week to get better at a tough topic. Each part of the plan needs ONE cast member's strategy — bring in the right one.
How do you make sure it STICKS across the week, not just today?
Who do you bring in?
Each study session, HOW do you practice so it counts?
Who do you bring in?
So you can TELL similar problem types apart, what do you do?
Who do you bring in?
The synthesis: spacing sets the calendar, retrieval makes each session count, and interleaving sharpens discrimination — three strategies, one week-long plan.
A good study week isn't one trick — it's these three working together.
