Learning through thinking

• Practicing critical thinking (i.e. the decision of whether to post a node and how to write it)
• Practicing metacognition (i.e. deciding whether to upvote/downvote and whether to improve a node or not)

Collaborative environment

• Collaborative mapping (i.e. reading a node from another persons understanding of that concept)
• Collaborative discussions (i.e. listening to someone else explain a concept or node in class)
• Signs of life (i.e. users monitor other users activity)
• Competition between users (i.e. who makes a post first)

Freedom of direction

• Learning by exploring (i.e. self-direction by choosing what to study)
• Ability to teach newer theories/concepts (i.e. the curriculum was able to build in concepts such as causal inference)
