student conferences
I have often, before I have a conference with parents, had students fill out a form telling me how they think they are doing, what they like or dislike about our classroom and ask for their suggestions on how THEY can improve their grades.
I use this information with the parents; sometimes to show that students know themselves that they are not paying attention, working very hard, or listening all the time. They can then team up with their child to help them achieve their goals.
It has worked out pretty well for me.
