What better way to know if you reached your students than to ask THEM? Students are the best critics and will be honest with you.
This survey can be used in upper elementary, middle and high school.
The first page has a rating scale with opportunities for students to explain their answers. The second page is more open-ended for student feedback. The third page is more geared toward student motivation and self-reflection.
Encourage students to be honest. They can submit this anonymously. Be sure to remind them that truthful answers are valued and that responses will not affect their grades!
