Hi Maha! I am not convinced that mess is a useful term as regards learning.

People make mess, mess doesn’t exist without judgement. A child who is playing with food or texture is making meaning.

A pile of Lego offers potential for construction. Mess is not the opposite of order, is not the opposite of preordained structure.

A semiotic space with rich affordances offers potential for biodiversity.

A pig in muck is not making a mess but maybe taking a bath.

So your order may be a mess for me because we view affordances for making meaning and relating to our social environment differently.

In conclusion, to advocate mess in my eyes is a means of provoking reflection on diversity but not a useful lens to present complexity.
