A screencast is a narrated video recording of your computer screen. A screencast can comprise anything from still images (for example, slides containing text or photographs) to full motion (for example, the movement of your mouse cursor, drawing or writing on slide, video clips from lab demonstrations, etc.). Using a screencast as a Content Activity can provide students with lessons they can watch at their convenience, as often as they choose, to review class material or to help understand concepts they find difficult.

The following is an example of a screencast:
