I (think I) first came across the ideas of Kelly and his Personal Construct Pscyhology in a paper or two or three, written by in-Japan-teacher Gregory Hadley.
Well, I’ve just spent a happy hour lost in the maze of James Atherton’s Doceo site, and came across this page on Kelly and Personal Construct Psychology.
Atherton also included a link to Phil Race’s website, in particular to this Powerpoint presentation on a further theory of learning, Ripples.
(Atherton teaches (taught?) teachers for many years. His writings are aimed at college teachers, but some of the theory of learning stuff would apply to learners of many (all?) ages.
