6.Practice
Everything will go better if the debate itself is not the first time the students have expressed these points. Practice enables them to find the best vocabulary - although they should be warned that every word they say should be understood by everyone else. They should keep an eye on the clock and make sure they can express their points within the time limit.
7Let’s Do This
Whatever happens, follow the format. The teacher can introduce the debate and remind everyone of the format and the rules. Then each team takes their turn. Make notes as you go, either as part of a continuous assessment system or just to keep track of who has made which point. Keep order and make sure everyone is paying attention and, if possible, taking notes; there is a special skill required to make brief notes on complex arguments, and it’s well worth practicing.
