The two articles I read to create this presentation were:
Bates (2015), ‘What do we mean by open in education?’
My original intention was to read the two most recent articles but I glanced at them all and found the Bates post complemented the Tait one in that they raise similar, although not identical, issues.
Both posts raised issues which, as I read them, seemed like common sense. Of course - both go far beyond common sense but the explanations and writing were clear and explicit and made their points seem self evident. Hopefully you can get a decent flavor of the posts in my presentation below.
