Sweep the Room

The steps

1. Pick a spot where you can see every face. A front corner usually reveals more of the room than the middle of the board, and from a corner nobody is behind you. Give your directions and teach the key moments from that spot.
2. Sweep after every direction. Give the instruction, then scan the whole room slowly along a set path, such as far corner to near corner. Take two or three seconds over it. This is the moment when the class decides whether the instruction was serious.
3. Give each sweep a job. Scan for the visible actions you asked for: pens moving, eyes forward, screens down. A sweep with a question to answer registers what a vague glance misses (see What-To-Do Directions).
4. Show them you are looking. Stand still, lift your chin and let your eyes travel openly. Narrate the scan from time to time, so that students hear that you are checking:
   Eyes this way… I'm looking for all thirty… thank you.
5. Keep the room in view during the busy moments. When writing on the board, turn back to the class between sentences. When helping one student, angle yourself so that the others remain in front of you. During pair talk, stand at the edge of the room and continue sweeping.
6. Follow what you see with something small. A sweep only changes behaviour when it leads somewhere. Respond to drift with eye contact or a gesture while you continue teaching, and respond to students doing the right thing with a nod or a brief thank you (see The Quiet Correction and Narrate the Good).

How you’ll know it’s working

• After each direction, the teacher's eyes travel the full width of the room, corners included, before the lesson moves on.
• Off-task behaviour is noticed within seconds of starting. Corrections are mostly looks and gestures, and days can pass between named public corrections.
• Film ten minutes of your teaching and time the gaps: the longest stretch in which you could not see the class, whether with your back turned or your head down at one desk, stays under about ten seconds.
• Students glance up to check whether they are being seen and find that they are. Side conversations end at eye contact, without a word.

Weigh it up

Why it’s worth it

• Much low-level behaviour never starts. Students behave differently in a room where they expect to be seen, so the sweep prevents incidents that every other technique would otherwise have to fix.
• The incidents that do occur are caught early, which keeps corrections cheap. Behaviour noticed in its first few seconds can end with a look; behaviour noticed after a minute tends to need a name (see The Quiet Correction).
• It supplies your positive voice with true material. Accurate narration and fair praise both depend on genuinely knowing who is doing the right thing (Narrate the Good).
• The same habit gathers information about learning as well as behaviour. A sweep during practice shows you who has started, who is stuck on question one and whose page is still blank, well before any marking could.
• It costs nothing: no resources, no lesson time and no set-up. The habit also transfers to every room you will ever teach in, including cover lessons and duty.

The costs

• Scanning deliberately while explaining carries a genuine cognitive load, and in the first weeks it can cost your explanations some fluency.
• Some rooms work against you. Pillars, computer monitors and awkward desk layouts block sightlines, and fixing this can mean rearranging furniture or negotiating over a shared room.
• The habit fades exactly when it is most needed, on the tired days at the end of term. It requires an occasional self-audit, such as filming a lesson, rather than a single week of effort.
