Week 8: social networking beyond text: YouTube in the classroom

Can teachers show videos from Youtube to a class or embed them in Web sites used for course material access, without infringing copyright or licenses?
Good question, one that I have wondered about often. There is something called "education exemption" which states: There is an exemption for educational institutions (Section 29.4 of the Copyright Act) which covers the use of materials in the classroom and during examinations. It is very restrictive; however, it is possible for a teacher to make a manual reproduction of a work onto a dry-erase board or flip chart for displaying hand-written materials; to make a copy for the purpose of projection using an overhead projector or a similar device; to reproduce, translate or perform in public a work as required for a test or examination. These exceptions must occur in-class only and on the premises of the university campus only. If I interpret part of this exemption correctly ... then it is fine for teachers to use YouTube videos as a teaching tool. To be honest though, I think that since the creation of the internet, copyright infringement has grown exponentially.
