Assessing Learning in #CritLit2010

Stephen Downes post on Semantics at Half an Hour: Having Reasons is devoted largely to the issue of how to establish the well-foundedness aspect of knowledge as well-founded true belief.

A large part of the discussion was devoted to the question of how confidently it can be asserted that "interesting learning" occurred in #CritLit2010. (With "interesting learning" apparently referring to the acquisition of new knowledge rather than just unfounded beliefs or behavioural responses - which are also of course examples of learning but not so interesting)

In the course of that discussion Stephen referred to slide 23, where the inference of learning appears to be derived from observation of behaviour in a social network. But it requires quite sophisticated observation to confirm that the behaviour is based on beliefs that are founded on good reasons as discussed in this posting. (For example it might involve observation of exchanges between members of the network when solving problems together and evaluation of the explanations given to one another in that process.) Also, there would have to be a change of behaviour (beyond that attributable to increasing familiarity with that specific network) in order to infer that the demonstated knowledge was newly acquired and so evidence of learning.  Given the looseness and scale of the network involved it would be a huge task to sift through all of the exchanges to identify signs of increased knowledge in even just a few of the participants.  So I must say I agree with those who are skeptical of Stephen and co's ability to provide convincing evidence that "interesting learning" has occurred (other than perhaps by direct testimony of the participants).
