An open source Course Management System (Modular Object-Oriented Dynamic Learning Environment) originally developed by Martin Dougiamas. It is used by thousands of educational institutions around the world to provide an organized interface for e-learning, or learning over the Internet.
It allows educators to create online courses, which students can access as a virtual classroom. Typically its home page will include a list of participants (including the teacher and students), a calendar with a course schedule and list of assignments. Other features may include online quizzes, forums - where students can post comments and ask questions - glossaries of terms, and links to other Web resources.
