Feedback
The feedback module enables you to create surveys for your students. Do not confuse this with the survey activity. In survey, you must choose from several pre-made surveys; you cannot build your own surveys. Also, do not confuse this with the questionnaire module. A questionnaire is an add-on, while feedback comes as standard with Moodle.
The feedback module needs to be enabled by the site administrator under Site Administration | Plugins | Activity modules | Manage activities.
Feedback isn't just for students
Of course, you can use a Feedback activity to survey your students. You can also use it to:
Conduct a survey of the employees in your work place
Collect data from people who have agreed to be research subjects
Conduct public opinion surveys of the visitors to your site
The feedback activity enables you to create different kinds of questions: multiple choice, dropdown, short answer, and more. You can share the results of a feedback with the students or keep it confidential.
