In an activity where students wrote a tough question on a post-it that they could answer, they then circulated the room and asked each other in pairs. If they both got it right, they switched post-its, if a mistake was made then the answer had to be explained.
During feedback following the activity, a student commented that some of the time if he made a mistake, the "asker" was able to give the answer but not explain it, so he didn't feel he'd learnt. So here comes the new self-assessment criteria (note the "yet"):
I intend to use this both as a whole class activity (using coloured ABCD cards) and also getting students to highlight in the margin next to a specific skill or question.
