Understanding and Applying Retrieval Practice in Lesson Planning

Retrieval practice—actively recalling information instead of rereading it—is one of the most reliable ways to strengthen long-term memory, and it can be built into lessons with two low-prep classroom routines. The core idea is the “retrieval effect” (also called the testing effect): information is stored and consolidated more effectively when students are forced to retrieve it at multiple points during learning. That matters not only for exam performance, but also for how well students can think critically and creatively later, because higher-level work depends on having a solid base of “remembering” knowledge to draw from.

Morgan frames retrieval practice as both necessary and uncomfortable. Many instructors avoid it because recall feels hard, getting answers wrong can be embarrassing, and classroom questioning can be awkward—especially when teachers already know the answer and students hesitate. Yet those negative emotions are treated as part of the learning mechanism: learning requires effort. The practical goal becomes making retrieval practice manageable and structured so students experience the challenge without stalling the class.

For the beginning of a lecture or tutorial, the recommended routine is a “pop quiz.” Students answer short questions drawn from prior course material, using tools such as Zoom polls, an overhead projector, or an online learning platform. The quiz should function as a learning activity rather than a high-stakes assessment—ideally ungraded or only lightly tied to participation. Crucially, retrieval practice only works when students receive immediate feedback on whether their answers are correct. Morgan suggests collecting responses right after the quiz so students who know the answers can share them with the rest of the class. Placing this at the start also primes memory: students retrieve what they already know, making it easier to connect new information to earlier concepts.

For the end of the session, the second routine shifts from quick testing to a discussion-based retrieval task. Students close their textbooks and raise their hands to name a topic covered in the day’s lecture, forcing them to retrieve freshly learned content. The instructor can capture the resulting list on a chalkboard for in-person classes or in a shared Google Doc for synchronous online sessions, with the added benefit of sharing the list afterward as collaborative notes.

To push retrieval into critical and creative thinking, Morgan adapts James Lang’s “one-minute thesis.” From the topic list, three students each select a term. Students then silently write a one-minute thesis that incorporates all three terms—an exercise that requires not just recall, but connection and argument. The format can be tailored to course goals; for example, in a theater context, students might write a one-minute play concept that integrates the three theories. The takeaway is to end class by having students remember and recombine ideas immediately, then carry that momentum into future lesson planning.
