How to create incentive for students to take surveys? I started to do questionnaires and surveys to assess my teaching methods and the learning gain of my students. How to convince the students to participate in these surveys? Is it OK to give small course credits for taking these surveys (say 1%)? otherwise, what are the incentive for the students to take these survey?
I think that giving some small course credit for a survey like that can be a good idea. Taking the IRB protocols as a model, you might give course credit for the survey, and also some alternate assignment for a student who has some point of principle that makes them not want to disclose personal info like that. Then you've really covered your bases.

In my own case, I give a study survey like that after the first exam. Since this happens to be in sequence and in the same format as three earlier quizzes, I think many students assume that it's for credit and complete it without me saying one way or the other (it's not, and has a different title, but it serendipitously works in my favor that way).
