Revisiting Inquiry Based Learning: Uncertainty-based teaching
Through Liverpool University, I've become re-engaged in the issue of Inquiry-Based Learning (IBL) - this time under the guise of research-based teaching and learning. IBL was one of the major things that I worked on at the University of Bolton's Institute f...

The problem of Information and Ergodicity
Information is not ergodic: the average surprisingness of an entire message is not the same as the surprisingess of a section of the message. So how does this affect the way we use Shannon equations? What makes information non-ergodic is the continual trans...

Finding the "Aesthetic Line"
The dynamics of human experience are such that there is continual blurring and shifting of focus. There are rare moments when focus brings revelation, insight and emancipation. At such moments, the contrapuntal lines of experience map each human being on ea...

Brains and Descriptions - some Agent-based modelling
Imagine that a brain is a set of constraints which produce multiple descriptions. The constraints organise themselves as a binary tree: with enough layers of recursion it quickly becomes very complex: In the diagram (left) produced in NetLogo, they are mult...

Reasoning and Cognition: The difference between Modelling Logic and Modelling Reality
I'm wrestling with the problem of formalising the way in which learning conversations emerge. Basically, I think what happens when a teachers cares about what they do, and reflects carefully about how they act, they will listen carefully to the constraints ...
