Assessment
1.Is there a set of the evaluation instruments available? Therefore, teachers could use these instruments in their classrooms to evaluate students' online performance. Another tricky thing is that there are lots of separate instruments in three papers to evaluate different perspectives of online learning. However, we still don't know the factors which impact online learning most.
2.Law listed five theoretical frameworks to assess learning outcomes in CSCL settings. Are there evaluation instruments available based on those theoretical frameworks. How can frameworks guide the instructional designers to design and facilitate the CSCL environment?

Support Groups and Healthcare
1. Galegher (1998)
legitimacy: Why do you come there? Legit reason for people to come here?
referring back to personal experience, referring by a doctor to a formal group
Authority: Why do people believe, trust what you say?
source of information,some form of testimony,how people write
How could online community offer guidance for members to evaluate the various treatments? One solution could be rating system. However,is the rating system enough such as the ebay online commercial rating system since medical treatment could be more serious.
2.Oxford Health literacy
The paper presents the definition of health literacy and overview of health education history. What's role of Web2.0 technologies in promoting health literacy other than tools to facilitate synchronous and asynchronous communication?
technology determinism-catch up with the technology
eg. technology drives school reform.
social determinism-perceived social needs drive technology evolve
BOT- technology agent

Social Presence
The concept of social presence was from the seminal work of Short, Williams, and Christie in1976. Social presence refers to the “degree of salience of the other person in the interaction and the consequent salience of the interpersonal relationships...”
1.Gunawardena,C.N.(1995).Social Presence Theory and Implications for Interaction and Collaborative Learning in Computer Conferences
Social presence is considered as a quality of the medium itself and hypothesize that communications media vary in their degree of social presence, and that these variations are important in determining the way individuals interact. The capacity of the medium to transmit information about facial expression, direction of looking, posture, dress and nonverbal cues, all contribute to the degree of social presence of a communications medium. My question is whether users’perceptions of media alter their behavior or the capability of the medium alter users’behavior?
2.Rettie,R. Connectedness, Awareness and Social Presence.
Christiansen and Maglaughlin (2003) classify four types of awareness: workplace awareness, which is knowledge of tasks within the virtual environment, availability awareness, which relates to the availability of people and objects, group awareness, which promotes the feeling of belonging to a group, and contextual awareness, which includes physical, social and mental context. Rettie states that extent of awareness is larger than the extent of social presence. I feel that awareness and social presence are interwoven. What do you think the relationship between awareness and social presence?

Reputation -Trust
1. The article "The Value of Reputation on Ebay: a Controlled Experiment" holds that eBay’s public reputation scores play a significant role in
the marketplace, and that virtually all significant sellers have strong reputations.
In statistics, if the mean is too high, it will be very difficult to analyze the true effects. Is it necessary to refine scoring system? If yes, what factors in the new system we need to consider?
2. Six degrees of reputation: The use and abuse of online review and recommendation systems by Shay David and Trevor Pinch
It has both advantages and disadvantages due to openness of online review and recommendation systems. As a buyer, I might need to be trained somewhat to be more cautious about the abuse of online review. It reminds me of the credibility of websites. When we think about whether to use information or not on a specific website, we also need to verify the credibility of this website. Could we say that they are the same issues?

Community,Networks&Participation
Gray- Informal learning in an online community of practice
As for research design, the study used CoP as a theoretical framework. I noticed that there are also some other studies which used social constructivist theory. Are there any difference between them? Since many participants in community are adults. I took a course "Adult Education" before. There is a theory called Andragogy. Is it possible to have more than one theoretical framework in one research paper?
McDonald & Lilia- legitimate peripheral participation
I am a lurker most of the time in a community. When I was applying for oversea study, I followed two websites regularly. Participants are the people who are the same with me or students who have been already in the USA. Lurking is a form of cognitive apprenticeship. Efimova(2004)said "Listening and reading is learning. It is getting to know community norms and language, picking up trends and staying updated, learning about others and their conversations. All this leads to an awareness of context that makes it much easier to become an active participant when the right moment comes." Unfortunately, the right moment hasn't come for me yet. I seldom go to these websites now. Basically, it means I never become an active participant. So how do you think about this time phrase "the right moment"?
