Low-level disruption — calling out, off-task chat, fiddling, distracting others — eats more learning time than any other behaviour issue. The least effective response is to escalate immediately to sanctions; the most effective is a calibrated, low-key sequence that handles 90% of incidents without drama.
The classic ladder is: non-verbal (a look, proximity, a pause in talking until eyes return) → verbal reminder (quiet, by name, of the expectation) → second reminder with named consequence ('if I see you turn around again, that's a detention') → consequence applied calmly. Each step gives the pupil a chance to self-correct.
