Moodle is an open-source learning management system (LMS) that provides educators with a flexible online environment for creating course content and engaging students. It was created in 2002 by Martin Dougiamas and is developed and supported by a global community. Moodle takes a social constructivist approach to learning by emphasizing collaboration and positioning learners as teachers. It is less rigid than other LMSs by not just focusing on delivering content to students. Moodle's open-source model means it does not rely on a single vendor for development and support.
