Can I show/play music CDs, Youtube videos, copyrighted movies, and video clips that come with my text book?
It depends. In a face-to-face classroom setting, as long as you determine it is a fair use, you may show video materials or play audio without permission unless the items were illegally made or obtained. To display a work in class, it must be for instructional purposes. In Blackboard, you can embed Youtube videos or link to other video or audio materials available on the Internet. While in-classroom use allows for playing an entire video, online use requires that only a “reasonable” portion be shown. As long as your students purchased the text book, and the clips are part of your instruction, you should be safe to show the clips in an online class.
