Having your students film themselves and edit using iMovie is something that can be integrated into any discipline. It would be a great way for students to present a drama presentation if they feel uncomfortable performing in front of their peers. It could also be an effective tool for having students make reflective vlogs, commercials, how-to videos and more. There's so much that can be done with this incredibly versatile tool. Even having your students research and present a TED talk as I have done below would be an interesting assignment.
Take a look at how I used iMovie to create my very own TED talk, enjoy!
