the highest market share of any CMS (open or closed) after
Blackboard. Moodle was created at Curtin University in Australia,

education philosophy, emphasizing interaction between students and
between teacher and student. Consequently, although it can easily
handle traditional classroom tasks like assignments and quizzes, it

tools, such as wikis and discussion forums. Moodle is implemented
in PHP and can use any SQL database as a backend; although it was

system that supports PHP and a database server can be used to host
a Moodle Web site."
