Linked

Jay Cross 读"Linked" ，从头开始认知社会网络和“六度分隔”(Six Degrees of Seperation)，我把大意都摘录过来，可以让更多人跟随着Jay的读书步伐了解更多社会网络概念和理解社会性软件（相比较那些同在英文世界的Blogger，我们做一些翻译也会比直接电子引用要多点学习体验吧，呵呵）：

在（二十世纪）六十年代晚期，哈佛大学的一个研究生 Mark Granovetter通过寻访麻省牛顿镇的居民如何找工作来探索社会网络。他非常惊讶地发现那些紧密的朋友反倒没有那些弱连接的关系更能够发挥作用。事实上，紧密的朋友根本帮不上忙。

想想看：你有一群非常亲近的朋友，你门只在这个小圈子里面走动，知道的都是相同的信息。没有什么机会可以在这个紧密交织的小群体中获得任何新的事情。

然而，你的每个朋友都还有在其他小群体中的朋友。这种认识关系让不同的信息流可以汇合。






既然每个联系人都对其他群组的朋友开放关系，朋友的朋友数量会不断快速增长。（待续）

因为还没有看到这本书，所以只好先随着Jay的读书步骤等下去了。不过不久，相信如"Linked" 网站所说，湖南科技出版社就要有中文版了，不知道书名如何翻译。

我也在收集更多“社会性软件”的资料而为下一篇文章做准备，也许还会有一些新思路。

"I would like to be able to implement blogs for use as reflective journals in philosophical discussion groups for advanced readiness readers. I think some students who might be reticent to participate in a whole class discussion might feel "safer" in this more secure thinking/writing environment."

"I'd like to combine blogging with cause/effect mapping. While I plan on doing groups of two, I can see assigning each group a different topic. This way, teams could react to the relationship between cause/effect maps. We could create a dialog between groups which would help us potentially create a master cause/effect map that combines the maps of each team in a class."

"I could use blogs at the end of a class. The students must post the answer to a wrap-up or closing question by either using a computer in class or as homework. The tag board could be useful for helping students to review for a test. A time could be scheduled where the teacher will be online to answer questions. I would not want to take some of the risks of giving 8th graders the freedom to post things on the internet (especially pictures)"

"If I had access to computers in my room, I would use the Weblogs tool for a review tool. 3 2 1 comes to my mind. After a lesson and for review purposes, I would have the students write down 3 things they learned, 2 things they could use and 1 thing they still had a question on."
