Hi Jean,
I use something similar to help me get feedback from my students throughout the course. I give them 3X5 cards and have them give me their feedback on the just completed assignment, project or activity. They don't sign the cards so they can be candid. I get great feedback and I have never to date received any feedback that was inappropriate. The students are honest in how they feel and that lets me get a read on the course as well as improve on the assignment,etc. next time.
