Over the years, I have found that one of the students’ greatest criticisms of any math class is their claim that they didn’t learn anything. Therefore, sometimes as part of their final, I have the students list ten things that they have learned. These items can be anything at all in relation to the class. They are allowed to write their list ahead of time and bring it to the final if they want. Most observations are quite normal, but some make for interesting reading. It has been a while since I have shared any, so I thought I’d do so here.
