Rowland’s Blog about e-learning matters

Had my attention drawn to an article by Stephen Downes which gave an extensive introduction to connective knowledge. It was very long and I can’t say I understood all of it but I found it thought provoking so I am making a note here to allow me to go back and read it again. I was not entirely convinced by the detail of some of the arguments though I agreed with overall thrust. For example the “red” apple does reflect a particular wavelength of light which can be defined to be within the red part of the spectrum. Stephen is not referring to the “absolute” that an apple is red but to our perception of the “redness” of the apple. The apple still reflects the same wavelengths whether we see it as red or not. That is of course as long as it is not a “green” apple.
