MITx is the massive open online course (MOOC) program at Massachusetts Institute of Technology. A constituent program of MIT’s Office of Digital Learning, MITx produces MOOCs from MIT departments and faculty that appear on the edX platform. MITx also supports residential experiments with scalable learning technologies and research on digital learning. MOOCs offered through edX by MITx are open-enrollment and free to take. Learners who successfully complete course requirements receive a certificate of accomplishment, but no academic credit is offered. In September 2012, edX and MITx introduced the option to receive an ID verified certificate for a modest fee on some courses.
