Canvas Studio is a tool built into Canvas that allows you to create video-based discussions and quizzes. You can use Studio to record videos of your computer screen, use your webcam, or both. You then can embed those within pages in Canvas.
Canvas Studio is a great tool because it allows you to create formative assessments using video to check for understanding. You can also use it to facilitate collaborative discussions as students can comment during your video if you choose to allow them to. For any screencast you create, you can use Studio to make adding it to you course easy. It will track who watches your videos. And finally, you can include captions to increase accessibility.
