Week 7: Web 2.0 Behaviors
2. In their article, Adar and Huberman discuss "free riders" on the Gnutella network and lament their damage to the community. This discussion made me reflect on my experiences (past only, of course) with downloading from peer networks. I remember, at the very beginning, downloading from FTP sites. Some allowed free downloaded, while others required that you upload in order to download. For these sites that required an upload, 1:1 or 1:2 ratios were not uncommon, meaning that you could only download an amount proportional to what you uploaded. Then came the peer networks ... Napster, Gnutella, LimeWire, KaZaa, and now BitTorrents. On these networks, especially the ones offering copyrighted materialas, of course there are a lot of freeriders. Why? Well it is the people who share, not download, who tend to be targeted by groups such as the RIAA. Do many people use services like Gnutella to share non-copyrighted material? While peer-to-peer services may have a noble calling, in my mind, they are mainly the way to obtain Warez (cracked or otherwise made-free commercial software), MP3s, video (TV shows and movies), and pornography. Are there actually legal uses (with the stipulation of people actually using them)?

Week 6: Blogs and wikis (well, mostly blogs in my readings)
2. The Glenn article discusses scholars who blog. I keep several blogs, but I don't keep one about my "profession." Why? Well, first of all, perhaps I don't feel confident enough to publish my thoughts/comments in such a public forum. Secondly, and this happens with any post I make, I wonder how my posts will reflect on me as a future employee of a company/univeristy, etc. I understand that blogs offer easy discourse, but then again, it is discourse that is not generally accepted as furthering knowledge, for use in promotion/tenure, etc. Would potential employers be upset that I am using my time to publish freely accesible information without any sort of formal peer-review process? Would they think that this would limit my publications or perhaps my status in the professoinal community? Do they think that, for any argument in the field, I would use the public forum to air my dirty laundry?

Week 5 Questions
As stated in the Johnson (1994) article, there are five major elements of cooperative learning:
- Clearly perceived positive interdependence
- Considerable promotive (face-to-face) interaction
- Clearly perceived individual accountability and personal responsibility to achieve the group's goals
- Frequent use of the relevant interpersonal and small-group skills
- Frequent and regular group processing of current functioning to improve the group's future effectiveness
This reading in particular dealt entirely with face-to-face groups. My question is, how does social computing or social technologies affect these elements? Are technologies a help? a hinderance? Both? Are there extra elements you would add when talking specifically about cooperative learning using technology? The Curtis and Lawson article focused mainly on text interaction, but what about technologies that are more advanced?
2. All of these papers talked about the benefits of collaboration, but in my experience, most students groan when they find out they have to do a group project. What causes this separation between research extolling the benefits of collaborative learning and the students that dislike groups? What is the role of the teacher to make groups more collaborative? What is the role of the students?

Video that ties with some of the readings ....
(WARNING: There is quite a bit of bad language in this link, be prepared).
In particular, focus on 1:30 when the kid asks his question. There is an interruption in between with some plot stuff, then back to the math problem at 2:55.
Week 4 Questions ....
1. In all three readings for this week, ideas about learning were presented that are do not necessarily gel with what is considered “traditional” teaching in today’s public schools. The Resnick article, in particular, examined how learning and application differ for school and the “real world,” and that was written in 1987. In our education classes, we’ve learned about more student-centered approaches such as constructivism, PBL, etc. In your experience, has public education evolved any in the over 20 years since the Resnick article was written, or are have ideas like social learning and ecological psychology actually had an impact in at the K-12 level?
2. Both the Saloman & Perkins and the Resnick articles discuss the use of tools by learners. Both indicated a debate about the transfer of skills to a tool from a person, with Resnick noting that as long as the tool has the skills, the system as a whole has lost no intelligence. I think this makes the point, though, that the person has lost that skill and would not be able to function that particular task without the tool. At what point do acknowledge the tool’s role and absolve a person from knowing those skills? For example, in early math classes I’ve taken, no calculators were allowed, though in advanced classes, calculators were required. When does this shift happen? Is it dictated by society? I can see a student now being puzzled about having to learn about multiplication or division when almost everyone has easy and immediate access to a calculator by way of phone and/or computer.
