Are you on the hunt for a free, open source platform that will let you deliver free online courses? We’ve already told you about one option: Google Course Builder. Now here’s another: Stanford’s Class2Go. The platform is open, meaning that you can grab the code base for free and run it on your very own server. Class2Go is also portable, giving schools the ability to move documents and media to other platforms if they so choose. The Stanford platform is interoperable in the sense that it builds on existing software (MySQL, Github, Piazza, MySQL, Python Django, etc.). And, unlike some other platforms, Class2Go gives educators immediate access to valuable data, allowing them to make refinements to the educational experience.
