Recently in my American History classes we covered a unit on Industrialization and development in the United States in the late 19th century. When we finished the unit, the students were assessed on the material. Assessment does not always mean a test, as we complete projects, essays, quizzes, etc, however in this case they had a test on the unit. I always prepare a study guide for the students and did so in this instance as well. Rather than discuss the study guide in class, I recorded audio of a discussion and shared it on YouTube with students to access at their own convenience.
I have done a few of these in the past, however my students this year really appreciated this method. (See picture below for # of views!) It allows them to study when they want-and not have to rely on just hearing the review in class. They may access this as many, or as few, times as they'd like. If they miss the class period we review during, they can still get every bit of information they need. YouTube is a great tool for this and many other practical solutions in the classroom. I simply recorded my voice on http://www.screencast-o-matic.com/ and uploaded my videos to my YouTube channel. You can capture videos, create photo slideshows, insert sounds or music, all from your computer's webcam on YouTube, and they have made it very user friendly and simple. I anticipate this being something that many teachers will be attracted to, as students today are busy-and the more access you give them to your material-the more they will access it!
