Good discussion of some of the questions associated with social software and learning. Questions like, "What new challenges and barriers does the use of social software create?" And, "Does the use of social software the encourage the development of depth of thinking?" The best take-away is this citation from Ulises Mejias: "Ensuring that the benefits of social software reach all circles of society will require that we focus not on the virtuality of social interactions, but on their reality... the desire for connection and understanding, the nomad's learning as becoming." Chris Lott meanwhile links to a series of items on social software and learning written by Tony Hirst, worth a look if you are interested in tthe tools or in how social software can be used in the classroom. Also: Chris Lehmann, Something Powerful is Going On. And still more, from Terry Anderson, Collaborative Learning Activities Using Social Software Tools.
