2. OpenStudy

OpenStudy is a social learning network where independent learners and traditional students can come together in a massively-multiplayer study group.

OpenStudy supports a number of study groups, including those focused on several MIT OCW courses.

3. NITXY

4. OER Glue

Still under development, OER Glue will be a site to watch. The Utah-based startup is building a browser-based tool that will allow students and teachers to “glue” together OER resources online. Rather than having to copy-and-paste resources into a new setting, OER Glue will reuse and integrate resources.
