This is a 20 minute assembly, or tutor period, or presentation to parents, showing students exactly how to revise so that they remember more of what they study. It shows them the cognitive science behind why revising in very small chunks works over time, and why only revising in the last month before the exams is a very poor strategy. It uses the analogy of eating an elephant to make clear why the best strategy is to revise in 10-20 minute chunks over the whole of year 11, or 10 and 11. It has a highly engaging embedded video of Twilight, Bad Lip Reading, in which you test students on what they have heard. It works - they all chant out the ridiculous answers. Example, what did he slap? Answer: A fish. You can use this to show how dual coding works: marrying images with speech really helps memory and explains why YouTube is your friend or, if you have bought it for your school, GCSEpod. Other explanations are of spaced learning, retrieval practice, interleaving, and elaboration. It also explodes three key myths about revision: reading, cramming and highlighting. You can see what the assembly might look like by watching my video on it in the link with this resource. There are over 50 slides - more than enough to adapt to your context.
