Quick answers
Interleaving: What is this, in one honest paragraph?
A practice of retrieving or structuring mixed practice on purpose, then checking, then repairing the hole.
Interleaving: What does the evidence actually say?
Rohrer and Bjork are among the names this atlas cites for mixed practice; treat their papers as public science, not as a brand.
Interleaving: How does it help a high-stakes exam?
It helps when the sitting asks you to produce mixed practice under time, not when the sitting only asks you to recognise a face.
Interleaving: How fast is a first honest gain?
A first honest lift is often a few honest sessions, not a motivational weekend.
Interleaving: What do beginners usually break?
Beginners skip the check step and call fluency mastery.
Interleaving: Which tools are enough to start?
A notebook, a timer, and a closed page are enough to start mixed practice.
Interleaving — what the studies actually show. The evidence list below names the studies that actually constrain mixed problem sets.
Scores here are relative ranks inside this atlas, not lab grades or official cut scores.
Evidence
- Classical source — Rohrer is the public name this atlas attaches to the origin story of mixed practice.
- Modern constraint — Bjork and later work keep mixed practice from being treated as magic: effort and test still matter.
- Exam listing — mixed practice earns its exam-fit score when the sitting asks for a name, number or chosen method under time.
- Dunlosky utility — Dunlosky's reviews treat practice testing and distributed practice as high-utility — mixed practice is one way to run them.
- Bjork difficulty — Bjork's desirable difficulty says a slightly harder retrieve of mixed practice beats a fluent reread.
Mechanisms
- Retrieval as encoding — Producing mixed practice from a blank page is a new encoding, not a photocopy of the reread.
- Error as signal — A miss on mixed practice tells you which fact to split or rewrite. A fluent reread hides that.
- Time-box honesty — mixed practice that only happens after midnight is a scheduling fail, not a character fail.
- Transfer test — If you cannot do mixed practice in a different room, you have context, not skill.
Researchers
- Rohrer — Rohrer is cited as a public scientific name for mixed practice, not as a private coach.
- Bjork — Bjork appears because later measurement tightened the first story of mixed practice.
- John Dunlosky — Dunlosky's utility rankings are the classroom constraint: mixed practice should earn its hours against cheaper rereading.
- Robert Bjork — Desirable difficulty explains why mixed practice that feels slightly late is often the useful one.
Educational atlas — not an official syllabus, medical advice, or leaked item bank. Interleaving: Keep the public outline in view and treat this page as method, not a leaked key.
