Flipgrid is a video-based web discussion platform that instructors and students can use within their Canvas sites to conduct discussions. This app works much like Canvas' built-in discussion tool, except users make video recordings of themselves for their discussion posts instead of typing out written discussion posts and responses to others' posts.
Check out this blog post addressing how Flipgrid can help meet remote learning needs in higher education.
The introductory video below covers the basics of using Flipgrid in Canvas, including how to install Flipgrid in your Canvas site, creating Flipgrid discussion assignments, and grading Flipgrid assignments in SpeedGrader.
