This paper outlines the use of “how to” videos, in the form of a screencast using a tablet computer, and posting the videos online. These videos are useful for when students miss a class, for those students who need to review a lesson or examples used in class when doing homework or reviewing for a test, for instructors of online classes, and also for instructors if they have to miss a day of class. Students overwhelmingly report this to be a useful and effective tool that has allowed them to catch up more easily after missing one or more days of class and for reviewing material from class.
