Interleaving
Mix topics in one session — don’t block them.
What the Research Says
Most students revise by blocking — an hour on the set play, an hour on practitioners, an hour on design. It feels productive and the topic seems clear by the end. Interleaving is the opposite: you jump between topics inside a single session. It feels worse at the time, and you’ll make more mistakes. But when the real exam arrives, you will be dramatically better at knowing which technique to apply — and that is usually the hardest part of any exam question.
Evidence Base
| Study | Finding | Impact |
|---|---|---|
| Rohrer & Taylor (2007) | Students who interleaved topics scored 43% higher on delayed tests than blocked-practice students. | Same time spent — huge difference in exam performance. |
| Birnbaum et al. (2013) | Interleaved learners felt LESS confident during practice but performed BETTER in the test. | If revision feels too easy, interleave. |
| Bjork & Bjork (2011) | Desirable difficulties — including interleaving — create durable long-term learning at the cost of short-term performance. | Short-term struggle is the price of long-term gain. |
| Taylor & Rohrer (2010) | Benefit was largest when topics looked superficially similar — students learnt to DISTINGUISH them. | Most useful where students confuse similar techniques. |
Step-by-Step Method
- 1Pick 3–5 related topics — topics that share a paper, a theme, or a question type. Similar enough that students confuse them.
- 2Make a mixed question set — 10–15 questions drawn from all the topics. Don’t tell yourself which topic each question belongs to.
- 3Attempt each question cold — first step is identifying what’s being asked. That identification is the skill you’re training.
- 4Mark after every question — note which topic each one was. Pay attention to mis-identifications — those are the highest-value gaps.
- 5Rebuild a new mixed set tomorrow — same topics, different questions. Different order. Over time, misclassifications drop.
- 6Expect to feel worse than blocked practice — that’s the right feeling. Your exam self will thank you.
Mix Section A and Section B question types in a single 40-minute session: answer a 4-mark question on the role of the sound designer, then switch to a Section B question asking how you as a director would stage the opening scene of your set play, then return to a Section A question on the differences between a lighting designer and a lighting operator. Switching trains you to shift rapidly between the technical-knowledge register and the analytical-design register — exactly as the real exam requires.
When revising practitioners, mix Stanislavski, Brecht, and Artaud questions in a single set rather than studying each one in isolation. A question might ask you to identify which practitioner used “the system” to develop realistic performance, then the next might ask how Brecht’s concept of gestus differs from Stanislavski’s psychological realism. Forcing yourself to switch between practitioners builds the discrimination skill the exam tests directly in Section A comparison questions.
Common Pitfalls
- Random, not related. Interleaving Drama with History is just subject-switching. Interleave WITHIN Drama — related topics that students confuse.
- Giving up when it feels hard. The discomfort is the signal that it’s working. Don’t revert to blocked practice because interleaving feels slow.
- Labelling the topic at the top of each question. Defeats the point — the identification IS the training.
- Using it too early in learning. You need baseline familiarity with each topic first. Interleaving is for consolidation, not first exposure.
When to Use This
Once you’ve covered a handful of related topics — usually partway through a term — start weaving them into mixed practice sessions. Very useful in the final 8–10 weeks before exams when you’re moving from learning to applying. Full past papers are the ultimate interleaving exercise, because they force you to shift between question types cold.
