The Commons in a Box (CBOX) group at the Graduate Center, CUNY and the OpenLab at New York City College of Technology, CUNY have released CBOX OpenLab:
CBOX OpenLab provides a powerful and flexible open alternative to costly proprietary educational platforms, allowing individual faculty members, departments, and entire institutions to easily set up an online community space designed for open learning.
Its name brings together two important ideas: openness and collaboration. Unlike closed online teaching systems, CBOX OpenLab allows members to share their work openly with one another and the world. Like a lab, it provides a space where students, faculty, and staff can work together, experiment, and innovate.
Like CBOX, the project is based on WordPress and is open source and free to use.
