Moodle is an open source web-based learning management system and a low cost alternative for educators to create vibrant online content.   The development of the Moodle platform was guided by a social constructionist framework of education which assumes that the knowledge a student receives is produced by the groups to which he or she belongs, or by particular discourse agreements. Moodle tools have an emphasis on:   group work, collaboration, communication, sharing, activities, and critical reflection.
