We use Moodle for course development. Moodle is an open-source course management system that has gained a large following among educators since it launched in the summer of 2002. The Moodle project claims 64 million users in 225 countries, according to statistics at Moodle.org. Moodle can scale to handle hundreds of thousands of students given enough server capacity and bandwidth. Educators, particularly early adopters of open source applications, have gravitated to the platform, which can be used to manage fully online courses or as an adjunct to traditional face-to-face classroom instruction ("blended learning").
