Educators have come to realize that videos are highly effective and engaging ways to create online course content. One of the most engaging forms uses a green-screen backdrop to project images or videos behind or next to the speaker. Barbara Oakley used this technique in her famous course Learning How to Learn, where she brought in images to illustrate and amplify her message during course videos. Take a look at this example and consider the fact that Oakley shot the videos in her basement using only a couple hundred dollars’ worth of supplies. Today most colleges already have green-screen studios set up for marketing or other uses.
