In this course, you will record yourself and share the recording with the instructor and your classmates as a YouTube video. You are welcome to use whatever technologies you like to create this video and upload it to YouTube. However, if you do not have a preferred way of creating and sharing videos on YouTube, then you may want to use Screencast-O-Matic. Screencast-O-Matic is a free, online tool that you can use to capture a screencast of up to 15 minutes in length. A screencast is a recorded video of a voice-narrated presentation or any other image that appears on your screen.
