Twitter Set Theory & The Wisdom of the Group Wednesday, April 9, 2008 Several weeks ago I was introduced to an idea that I have found to be profound in its simplicity but complex in its implications. In an informal discussion about educational technology at EduBloggerCon West, Steve Hargadon described the kind of learning that is taking place in today's social networks. Interestingly enough, I caught the discussion via Ustream (and participated remotely within the Ustream chat), demonstrating yet another facet of this idea. I will paraphrase what Steve has come to call "the wisdom of the group": You don't need to have everybody in the room in order to have a good conversation. In other words, once you reach a certain number of people - local experts, if you will - you can have very rich dialog without requiring that all of the experts be present. Steve has found this to be true in many of the social networks that he frequents, and I have found it to be true in Twitter. In the days following our discussion, I have drawn up several diagrams that I think demonstrate additional dimensions to this concept (they also fit in nicely with this fine collection).

I recently read a very interesting post by Terry Anderson, Edublogers as a Network of Practice. Network of Practice - a distributed aggregation of members who share some common interests and values, but their correspondence and especially face to face meetings occur much less often or not at all. Leadership and activities in a NoP are emergent and usually informal. NoP members interact sporadically and develop their network in an informal and spontaneous manner that is occasioned through blogs, social software based communities, perhaps a face-to-face or online conference, newsgroup, mailing list or other shared social networking interactions. Membership in a NoP is voluntary, usually open, often transitory and likely many of the NOP members are strangers to each other.

Pointing to the 'Social' and the 'Network' in making the case for social networking (twitter edition) Posted on April 5th, 2009 admin 10 comments I recently did a presentation for a senior administration group on campus at UPEI and, in combination with some very good questions from PatParslow about how I talk about organizing my twitter account, I figured it would better mark my learning and potentially prepare these thoughts for a more deeply thought article to post it here and get some feedback from you fine folks if the topic interests you.

As a follow on to the discussion of social learning and formal learning in Long Live … great post by BJ Schone - Have LMSs Jumped The Shark? I constantly hear people (across many organizations) complain about their learning management system (LMS). They complain that their LMS has a terrible interface that is nearly unusable. Upgrades are difficult and cumbersome. Their employees' data is locked in to a proprietary system. Users hate the system. It's ugly. (Did I miss anything?) We've recently seen LMSs shift to include more functionality, such as wikis, blogs, social networking, etc. I think they're heading in the wrong direction. I don't really understand why LMS vendors are now thinking they need to build in every possible 2.0 tool. If I want a great blogging platform, I'm going to download WordPress (it's free and has a huge support community). If I want a great wiki platform, I'm going to download MediaWiki or DokuWiki (also free and they have huge support communities). And when it comes to social networking, as a co-worker put it, "Do they really think I'm going to create a 'friends' list in the LMS? Seriously?"

I've been preparing a class session on communities of practice this weekend, and it's been underscoring for me just how important people are to an effective learning environment. We're independent adults, and we like to think of learning as something that each of us does for ourselves, but all the terrific resources in the world can't hold a candle to the power of what can occur between people.

A couple of short videos on communities of practice. The first is from Dave Vance, former president of Caterpillar University, who shares some of Caterpillar's experiences in facilitating online communities of practice. His advice?
