New tool to mine the collective knowledge

Thanks to the DownLoad Squad I bumped into a very interesting tool to mine collective knowledge. Avanoo is a social software tool that allows members to query others through simple Likert like scale items. Nothing too new here except that everyone gets to view and segment the results according to demographic criteria including gender, nationality, age, income level etc. For example I can create a questions and then determine if Canadians answered that question differently than non-Canadians, men differently than women or the wealthy differently from the poor. If I want I can augment my response to any question with a comment or explanation. Again nothing too new here, except that this type of analysis and results are usually costly to gather and remain the property of the survey owner, not the recipients.

McLuhan’s Laws of Media and the PLE

During the last eight years of his life the Canadian media theorist Marshal McLuhan worked on developing and validating four “Laws of Media” He argued that every new media Enhances through new affordances, Obsoletes through improvements in form, function and cost; Retrieves older patterns of behaviour and Reverses when over stressed into older, non functional patterns.

This work was published posthumously in text in 1988 as the Laws of Media: The New Science and covered in the 2002 NFB video McLuhan’s Wake. According to McLuhan these four immutable laws effect all media and understanding them helps us to fathom both the intended and the unintended, the positive and the negative aspects of every media. McLuhan was fond of challenging readers and audiences to think of a medi that did not demonstrate all four laws or to think of the 5th law or argue why they should be reduced to only three.

Dale Hunshler (2001) overviews Mclulan’s wider theories and notes how the web itself, illustrates the four laws of Media.

In this post I extend that work by very briefly applying McLuhan’s Laws to Personal Learning Environments (PLEs).
