Students sometimes take a bloody long time to learn. There have been blog posts about how progress doesn’t necessarily demonstrate learning and blog posts arguing that progress isn’t linear. Sometimes students might learn loads in my lesson; sometimes they might learn squat (hopefully not often). What my students need to do, however, is demonstrate that they can see the bigger picture in their learning and demonstrate that they are learning over time.
During one of my lessons recently, my year 9s were writing for the majority of the lesson as they were intent on showing me their learning over the module with the piece of work they were producing. Without that time to write, they would not be able to demonstrate their learning in a written format.
