Exit Ticket

Wish survey and reflection
This activity is in two parts the first to be done on the very first week of semester, here the students will write why they have enrolled in the course, anything they know already about the subject (if anything), what they are hoping to learn, what they think they will find challenging in the subject.
At the end of the semester the students go back to what they wrote in week one and write a short reflection on what they now know, if their worry about challenges did/did not eventuate and if this experience has opened new ideas/possibilities/etc.
