Quiet Signals
Non-verbal or semi-verbal cues a teacher uses to pull attention back from a noisy activity without raising the voice. Common forms include a raised hand, a countdown ("five, four, three…"), a clap-back pattern that learners echo, a chime or bell, switching the lights, or a phrase the class is trained to respond to ("Class, class" / "Yes, yes").
How they work
A signal works because it is taught explicitly, practised on the first day, and applied consistently. The mechanic is simple: the teacher cues, learners replicate or comply, the room falls quiet within a fixed expected time. The Wongs argue that procedures of this kind are the spine of an effective classroom: a signal that has been rehearsed three times is faster and calmer than any improvised verbal command. Lemov's "100%" technique sets the same expectation: attention is binary, and the signal does not move on until everyone is with it.
Advantages over voice-projection commands
Shouting over a noisy class is exhausting, models the dysregulation the teacher wants to dial down, and trains learners to wait for escalation before responding. A quiet signal does the opposite: it lowers the room rather than out-volumes it, costs the teacher no vocal load, and works as a marker for transitions between stages. Because it is non-verbal, it is also language-agnostic, useful in low-level classes where a complex verbal command would not register.
Implementation
Pick one signal and stick with it. Teach it in the first lesson: model the cue, model the response, rehearse with a deliberately noisy mock task, and reset if the response is partial. Keep the expected response time short — three to five seconds — and reset whenever it slips. A signal taught well in week one saves the teacher the same minute, repeatedly, for the rest of the course.
