Responses are collected in course context and can be seen by trainers and non-editing trainers. Access to the questions and the results are given by a simple block. It differs the approach of pre-defined "Feedback" in that way, that a block can be made sticky and feedbacks are optinal for teachers (they may use it or not).
If you want to force the evaluation, you have to make this block sticky on each course page. See the github project page or README file for further instructions.
