plickers would also be a great tool for giving feedback. Since you don’t have to match codes to people, it is possible to get an immediate and anonymous feedback (for whatver). (It is allreay possible, I know, but I think such questions should have another category…)

For that purpose another question category „assessment" or „evaluation“ or „opinion check“ beside (true/false and multible choice) would be helpful.
you could ask something like: Do you agree with… How did you like the...
1. I agree very much, /Very much
2. I mostly agree/
3. I don’t care/ a little
4. I disagree/
5. I strictly disagree/ not at all

Also, more than 4 answers would be perfect :-)
