Core readings

Bonus readings:

• Suthers, Dan. (2001). Towards a Systematic Study of Representational Guidance for Collaborative Learning Discourse. (this is where Suthers lays out a lot of the theoretical background for his work summarized in Suthers (2008) above)
• Stahl, Gerry (2006). Supporting group cognition in an online math community: A cognitive tool for small-group referencing in text chat.

Some suggested questions (feel free to add more, by editing this task, or commenting)

• What is the connection between "contested meaning making" in Liddo and Shum, and Knowledge Building? Are they similar? What about the tools they propose?
• How can you use Suthers' article to analyze Knowledge Forum, or other tools you know of (Etherpad?)
• Imagine how we could use deictic indexing/referring from Stahl (2006) to improving Etherpad. Any other tools that could be improved in this way? 
• Are there aspects of collaborative tools that don't fit Suthers' categories?
