Shannon,Your diagram is really easy to follow. I like that you broke apart communication in to synchronous and asynchronous. ACK! My topic is MMORPGs and I didn't include them myself! Good job on including MUDs and MOOs, though I am not sure how much they are used these days. They were definitely the industry pushers for online collaborative social cognition within the gaming industry!
Shannon- nice graph-easy to read- just wondering....I understand you deal in the special education area and was just wondering how many of these tools do you use in that setting? Unfortunately, our students have multiple disabilities and alot of these tech tools are not appropriate and do not support there IEP's. Any thoughts on how to use these tools in my setting to enhance their education?
