As teachers at the end of professional development courses we will be given an evaluation form to fill out. This gives important feedback to the leader and their company on the quality and relevance of the course.
We can adopt a similar process using www.surveymonkey.com. This allows us to write a questionnaire to give to our classes after we have taught a topic, module or even a whole year. The questionnaire is sent to pupils as a web link and they will be able to complete in their own time. You will recieve the results of the questionnaire as anonymous feedback. The feed back be used to plan future topics better in general or tailored to a particular class.
