Video creation can be used for several different tasks in the classroom. One that I have first hand experience with is when the teacher is sick. Illnesses can come up unexpectedly. Because of video creation, the teacher can upload a video to their class web page and then the students can watch the lecture if the teacher can not make it to school. Also students can get sick. So this would also work on a daily basis to record videos and upload them so students can go back and review what they missed. If you haven't messed around with creating a video, you should!
