iMovie is an incredible tool for education. You can have students make video presentations, documentaries, book reviews, news, and so much more. Learning about to edit video is an important tool as it has become such a popular media medium. I’ve used iMovie frequently in my own classroom, students love to make Stop Motion videos.
iMovie does have its issues. You are limited to Apple devices, the editing effects are limited, and it takes up a large amount of stage space. If you are teaching video production to students K-8 I would use iMovie, higher up you should be using Final Cut Pro or Adobe Premiere.
iMovie is very user friendly, simple, and can have some powerful effects. My favorite part of iMovie is how easy it is to greenscreen, check out my video on how to greenscreen, made with green screens!
