Math 8 – Students check over their answers with my answer key and also did a good job of correcting my answer key. I’m always honest about my ability to make mistakes. I think this is a good thing, up to a point. We still have to model good habits, hard work to get to a correct answer, and an appreciation of doing good work.
And no, I’m not going to collect 85 sheets of work and put a bunch of checkmarks on them, or give them marks. I do give out a lot of feedback as I walk around the class for 60 minutes. I do believe that custom feedback would be better but I don’t have time for it, and research shows that written feedback is most often ignored by students.
