Online education is reshaping learning across higher education and the workplace, from distance-enrollment to corporate training. This page maps adoption in the U.S. and globally, the technologies behind learning platforms and LMSs, and the learning analytics used to measure effectiveness. It also connects training approaches to outcomes, including evidence on active and blended strategies versus more traditional instruction.
Key Takeaways
