Learning involves a change in long term memory. If pupils haven’t remembered something there may have been limited benefit in doing it in the first place. Over the years I have seen a lot of lessons that have been “memorable” where the pupils have remembered the task but not the learning. They remembered making volcanoes out of Plasticine but not how an eruption occurs, they remember the primary school project on the River Nile but not where rivers start and how they flow.
Lets not plan memorable lessons but memorable learning instead.
