The original designer of Moodle. He's a genius.

Quoting:
"When designing Moodle, I wanted a set of values that could act as a compass:

• everyone should be a teacher as well as a learner
• if you understand the context of a person, you are able to teach them better.
• a learning environment should be flexible; as you learn more about the people in it, you're able to change it
• learn by doing and constructing and learn by engagement
