I’ve found that reflection is something that students ( and most adults) don’t do naturally, but it’s an amazing skill to have. I have students complete the reflection form when there are still about 3 weeks left in the course . ( however, do what works best for you and your students, or consider having them go through the process more than once.) This allows for them to respond to what they see written on the page.
It always makes grading easier on you, the teacher, as the students have already begun to self assess, they’ve started the conversation. The reflection process forces them to be honest, and really look at their work. After students go through the reflection process, rarely are they surprised by their final score.
