This document is a sheet that helps students to assess their own work habits.
It includes a rubric, a checklist, and a place for them to write a bit about what they do and don't do in class.
It follows with a space for them to give themselves a grade based on what they think they deserve. Then there is a space for you to write their final work habits grade.
It is proven that students work better when they have a hand in what they're doing. I've found that this activity allows students to realize where they've been lacking and where they've been excelling. And they tend to be very honest in their assessments.
