Some use experience on Moodle

Advantage:

• The whole Moodle is based on an open system, you could add, delete, modify anything you want. In Moodle, you could get a unlimited extensibility.
• It's very powerful. For a teacher, he can get full creativity to do what he want.
• Moodle could bring a whole new concept on teaching.

Disadvantage:

• Moodle is bsed on open open system. So anyone can develp new distribution from Moodle.
• It's powerful, so, it's hard to master. A teacher or student could not use it if they are not be trained. In China, not all teachers are high-educated, so maybe powerful Moodle is not suitable for them.
• The Moodle's target is noncommecial, so how to convert it to commercial, it's a question.
