Lesson Rehearsal

Lesson rehearsal is the practice of running through a lesson — or critical segments of it — before delivery, to test instructions, timings, board work, and likely learner responses. It is a routine feature of teacher preparation in pre-service training and a recognised technique in core-practices teacher education in the United States.

What rehearsal looks like

A typical rehearsal walks through the staged moves of a lesson aloud, or with peers acting as learners, to check whether the planned sequence holds together. The teacher delivers their intended instructions, anticipates learner responses, drafts the board (or rehearses screen sharing), times each stage, and revises whatever falls apart under simulation. Rehearsal can range from a minute or two of muttering through an instruction sequence at a desk to a full peer-acted run-through of a problematic segment. In CELTA and Trinity CertTESOL settings, trainees often rehearse instructions and concept-checking questions with course-mates before the assessed lesson.

Approximations of practice

In American teacher education, rehearsal has been formalised under the heading "approximations of practice" — staged simulations that sit between studying teaching and doing it for real. The approach grew out of the core practices movement led by researchers including Pam Grossman, Magdalena Lampert, Megan Franke, and others, who argue that complex teaching moves need rehearsal in low-stakes settings before they can be performed reliably with real learners. The pattern echoes professional preparation in fields like law and medicine, where moot courts and standardised-patient simulations precede live practice.

Distinction from microteaching

Rehearsal overlaps with Microteaching but is not identical. Microteaching denotes the Stanford-origin model of teaching a short, scaled-down lesson to peers, recording it, and analysing the recording — an assessment-leaning practice with an explicit observational protocol. Rehearsal is the broader, lower-formality act of practising any portion of any lesson before delivery, with or without peers, with or without recording. In practice the two blend: a rehearsal that is recorded and discussed against criteria becomes microteaching.

Use beyond pre-service

Rehearsal is associated with pre-service training but is not confined to it. Experienced teachers rehearse new techniques, complex demonstrations, and high-stakes lessons (formal observations, parent-facing classes, demonstration lessons in interviews). Demand-high or exploratory teaching practices that ask teachers to rework familiar material into more cognitively demanding tasks often presuppose a rehearsal step where the teacher tries the harder version aloud before using it.
