Debate is often dismissed as impossible in a class of sixty, on the reasonable grounds that only the confident few will speak. This format solves that by removing the audience: pupils debate in fours, simultaneously, all round the room. The noise is considerable and the participation is close to total.
Every pupil is given a role, a position they did not choose, and a set of sentence frames. Being assigned a side matters more than it sounds, because it separates the argument from the person and makes it safe to lose. The frames matter because they let a pupil with modest English take a full turn without inventing structure under pressure.
Eighteen debate motions are included, chosen to be arguable by secondary pupils from their own experience and to avoid subjects that could put a teacher or a school in a difficult position. Guidance on choosing further motions safely is included.
