If you learn a handful, learn these.
Impact 6. Strong principle evidence.
The 14 impact:6 core methods: session role, evidence, and one-line action.
1
Prerequisite diagnosis
Find the earliest missing idea before studying the new one.
2
Contingent hinting
One hint at a time; attempt between; never the full solution first.
3
Free recall
Write everything unaided; rank gaps by cost.
4
Immediate targeted feedback
First error, belief behind it, one question. No solution yet.

Spaced schedule design
Revisit from forgetting, not from the calendar.
Interleaved problem sets
Mix types so selection, not only execution, is trained.
Successive relearning
Retrieve to criterion across separated sessions.
Interleaved spaced retrieval
Mix topics and space each item across days.
Socratic questioning
Answer escalating questions; receive no explanation.
Error cataloguing
Log mistakes by cause; re-test the pattern.
Self-explanation prompting
Explain each step while studying; flag hand-waving.
Illusion-of-fluency check
Catch recognition masquerading as recall.
Desirable-difficulty tuning
Keep practice hard enough to work.
Retrieval via reconstruction
Rebuild the structure from scraps.
