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"?

Friendships&Relationships 2Qs
Self-disclosures with on-line acquaintances are similar to the “strangers on a train” phenomenon, in which people sometimes share quite intimate information with their anonymous seatmates (Mckenna,2002)
Relationships sustained primarily over the Internet are not as close as those sustained by other means such as face-to-face meet, or phone(Cummings,2002).
Two researchers’perspectives are different. The first one focuses on information intimacy. The last one focuses on people’s perceptions about relationship. Understanding parameters that shape the quality of interpersonal experience is crucial to compare different means of communication. What are some of the parameters?
I think maybe because human beings are so complicated that have a multitude of aspects and needs. As Tyler (2002) said “Change in technology, with its resulting changes in the way people live their lives, has not led to changes in well-being or the quality of people’s social relationships. I agree that “While the modalities of life rapidly evolve, the fundamental issues of life that people are seeking to address remain more constant, with people seeking tools to better live their lives” (Tyler, 2002).
Do you think being a digital native or a digital immigrant will play a different role in online social relationship? If yes, in which way?
Internet is changing the nature of work, government, and social relationships. One good example is to go green with paperless. Would you like to share some internet-generated benefits?

Technology Behavior 2Qs
1.Golder’s Collaborative tagging systems(2006) remind me of knowledge management as an approach to data mining process for socially constructed intelligence. Data mining refers to the process of discovering meaningful new correlations, patterns, and trends by sifting through large amounts of data stored in repositories and by using pattern recognition technologies as well as statistical and mathematical techniques. Therefore, there could be some applications in analyzing community of practice such as frequently shared knowledge, sustainability, and emerging patterns. What other applications do you think of?
2.Suler’s online disinhibition effect(2004) is really interesting. I am wondering what personality variables’ role in influencing the extent of this disinhibition? There are both benign and toxic disinhibitions. When a person becomes a member in a community, should this community verify his or her identity in reality? If not, will it hurt the reliability of the community?

2Qs for Blogging & Wikis
1. Kumar’s structure and evolution of blogspace(2004)
In this view of the worldwide blogging network, a “community” is a set of blogs linking back and forth to one another’s postings while discussing common topics. It’s interesting to see people work so hard to come up with various definitions about community. Do you agree with this viewpoint? If so, what constitute a community in Wikis?
2. Nardi’s blogging as social activity (2004)
People typically found blogs through other blogs they were reading, through friends or colleagues telling them about their blogs or those of others, or through inclusion of the blog URL in an instant message profile or a homepage.
It reminds me of Watts’ theory about Six Degrees of Separation. Does it apply to blogs or maybe much easier for us to connect to people around the world through blogging?

2 Qs for collaboration and cooperation
1. Curtis Collaboration
Dillenbourg and Schneider (1995) make a distinction between cooperative and collaborative learning. They indicate that cooperative learning is “… a protocol in which the task is in advance split into subtasks that the partners solve independently”. Collaborative learning describes situations “… in which two or more subjects build synchronously and interactively a joint solution to some problem”. This distinction places greater emphasis on the extent and quality of the exchanges that occur within groups of students in collaborative environments.
Social constructivism extends constructivism into social settings, wherein groups construct knowledge for one another, collaboratively creating a small culture of shared artifacts with shared meanings. Therefore, to what extent and in which social organization their concept of this distinction has been accepted?
2. Roger and David’s cooperative learning
“The joint success experienced in working together to get the job done enhances social competencies, self-esteem, and general psychological health.” I like it and believe it too. When I was EDCI 270 teaching assistant last semester, Professor Newby did ask the students’ team work experiences before team project. However, what I witnessed are there were much more students who claimed they did not like team work because of past bad experiences. Are our researchers over optimistic about team work in real school settings? Is “publish or perish” a main factor to result in the isolation of fruitful research and many educators and students’ true perception?
I like the notion that cooperation is for efficiency while collaboration is for effectiveness.
What's the purpose for students to work cooperatively? First, the teacher requires that. Second, workload is so heavy that needs to be split up. Last but not least, teachers get used to work cooperatively. Teachers teach in the way they were taught.
The power of working collaboratively: The ability to work collaboratively is recognized as a core competency of a learning organization.
Establish trust is fundamental to the successful formation and growth of team work. Collaborative learning, as the basis for effective organizational team building, requires a level of personal familiarity, intimacy and trust, allowing team members to listen to one another with respect and understanding (Comstock and Fox, 1995).

Typical Graduate Student
Duncan Watts, the author of Six Degrees: The Science of a Connected Age wrote the following about his graduate study:
"Thinking like a typical graduate student, I assumed that the coupling topology question was an obvious one, and therefore the answer must have been worked out long ago- all I needed to do was look it up. Instead of the answer, however, I only found more questions."
Isn’t it interesting? First I read this, I could not help laughing. I also have this tendency to think that my research question is trivial or has been answered. After diving, you will find something unique you can contribute. Critical thinking is a vital ability to be developed and encouraged during graduate study. It does not come from the wind. It comes from extensive reading and writing practice, intentionally and continually challenging my mind, and sometimes focusing on one spot longer.
What is six degrees of separation? Everybody on this planet is separated by only six other people theoretically. One significant factor is the difference between being connected to someone with a short route and being able to actually find that route. Meanwhile, the distance of foreign settings makes the potential for connection irrelevant. That’s why goal sharing could make community thrive.

2 Qs
1. Individual and social aspects of learning
Social mediation (the cognitive, acquisition-oriented) enhances the individual’s learning as individual, striving to improve his or her mastery of knowledge and skill. The more radical (the situative, participation-oriented) sees the individual and the social agents as a unified learning system the learning outcomes of which are both situated in the particular interactive context and distributed among the participants. As for the first one, evaluation could be fulfilled by performance test. How to implement evaluation based on the second viewpoint?
2. Weight watchers program
This example is used in two papers. One paper is the 1987 Presidential Address. The other one is an ecological psychology of instructional design. The first paper used this example to distinguish between symbol manipulation in school and contextualized reasoning outside school. The second one used it to exemplify the perceiving-acting cycle. I think it could serve as a good example of information interpretation. In which way information interpretation could facilitate (or hinder) community knowledge construction?
Three categories of learning theories are always addressed in EDCI courses. The systematic structure of the course requires instructors to overview learning theories at first. Generative principles are concluded:
Behaviorism
• Empty mind
• Stimulus/ response
• Feedback/ response
• Law of effective
• conditioning
Cognitivism
• Information processes
• Prior knowledge
• Memory
Constructivism
• Authentic tasks
• Problem solving
• Participation
• Collaboration
• Experience
• Meaning making
Nice things about this part is to apply learning theories into different contexts such as instructional design, science education, and adult learning. The unique cue this time is to highlight the agent. Condition, teacher, and mind serve as agents for each learning theory. Before that,I usually distinugish them in terms of the view about knowledge and the role of the student in learning.

new Obama administration's agenda for education
The new Obama administration's agenda for education can be viewed online at http://www.whitehouse.gov/agenda/education.
The change in Washington may signal new opportunities for funded projects, particularly in collaboration with K-12 school partners.
There are some points I am interested:
K-12
1. Make Math and Science Education a National Priority: Obama and Biden will recruit math and science degree graduates to the teaching profession and will support efforts to help these teachers learn from professionals in the field. They will also work to ensure that all children have access to a strong science curriculum at all grade levels.
2. Recruit Teachers: Obama and Biden will create new Teacher Service Scholarships that will cover four years of undergraduate or two years of graduate teacher education, including high-quality alternative programs for mid-career recruits in exchange for teaching for at least four years in a high-need field or location.
3. Retain Teachers: To support our teachers, the Obama-Biden plan will expand mentoring programs that pair experienced teachers with new recruits. They will also provide incentives to give teachers paid common planning time so they can collaborate to share best practices.
