Moodle (abbreviation for Modular Object-Oriented Dynamic Learning Environment) is a free source e-learning software platform. Moodle can be used in many types of environments such as in education, training and development, and business settings and with its over 50.000 registered sites, is maybe the most renown and used platform at this time.
Moodle has several features considered typical of a learning-platform:
Developers can extend Moodle's modular construction by creating plugins for specific new functionality. Moodle's infrastructure supports many types of plug-ins:
- activities (including word and math games)
- resource types
- question types (multiple choice, true and false, fill in the blank, etc)
- data field types (for the database activity)
- graphical themes
- content filters
- also many freely-available third-party Moodle-plugins make use of this infrastructure.
Even though Moodle is free source, you will normaly need some provider to host the platform and deal with back-end administration, as this requires experts. But many universities work with Moodle and therefore have their own Moodle administrated by the universities computer center.
