I use this sheet when students need to bring up their grade due to low test scores. It is editable so you can make it work for you. Students have to give the correct answer to the test question(s) they missed. Then they need to give TWO specific details as evidence that this is now the correct answer. I explain that details could be more information, definitions, examples, analogies, etc., but that the details must be different and must not be merely restating the question and answer. Details must be accurate.
