2.14 May I post examples of my students’ work on my Waterloo's learning management systems (LEARN) course or on my personal website?

Only if you have the student’s permission. Under the University’s Ownership of Student Work policy, students own the copyright in the works they create. The University does get the right to make copies of the work for academic purposes, but this right does not extend to making it available online. Accordingly, you should ask students in advance whether they consent to having their work posted online and keep written records of the permissions given.
