When I was trained to teach, it was assumed that teachers would orchestrate the ending of a lesson, perhaps channelling my childhood music teacher who used to say, ‘If you start well and end well, people forget the mess you made of the middle.’ Not that we want children to forget the middle of the lesson – quite the contrary – but there is some lingering belief that if we end our lessons with a ‘bang,’ the learning is more likely to magically stick.
