Recently a colleague reviewed her Year 11 mocks by filling in a fresh copy of the exam paper with “silly mistakes”. For each question, she wrote a response illustrating one or more key misconceptions she had noticed when marking. Students then worked in groups to correct the errors.
Last year I did something similar with my Year 9s. As I was marking their practice SATS papers, I took photos of responses that were partially correct but contained errors. I posted these on our class blog and, for that week’s homework, asked learners to identify the mistakes.
