Codio is an indispensable tool for teaching! The rich set of learning materials available in the platform makes Codio suitable for introductory and advanced computing courses.
Having all students use a common platform requiring nothing more than a browser on their machine is fantastic. Students benefit from not having to download or install anything.
Further, the features, from the ability to open a student's project directly to support for team projects, auto-grading, and more, are well implemented and very easy to use. Lastly, the Codio team provides terrific support, I usually get a response in minutes.
