Part 1 So what?

• Collaboration has to be structured.
• Web environments provide the structure by making

• ergonomics,
• timing,
• didactic contract,
• Integrate communication in the task.
• Collaboration has to be regulated ()

• Contextuality (keep the context with the message)

Distributed Cognitive System
