Any pedagogy invoking chaos theory as a justification is probably nonsense, or partially nonsense.
It appears that descriptions of cognitive functions as being rules by chaos theory are, at present, merely speculative, and no empirical evidence exists to suggest that this is indeed the case.
No paper arguing for the application of chaos theory I’ve yet read mentions the three necessary conditions/ characteristics for chaos and none tackles the line between the deterministic aspect of mathematically modelled systems and the forms of relativism espoused.
Given that chaos theory seems to be a function of mathematical modelling, and is a mathematical theory, any application of it that doesn’t do the math can be ignored. The application of chaos theory is mathematical, it’s description and expression is mathematical. If the paper doesn’t show it’s work, or it’s work isn’t maths, we can ignore it.
