"I would not argue that (2) and (1) are easily separable. Is it possible to
study a theory without it being a theory of something?" BB
Yes. That "separation" is only possible in a heuristical (in the sense of an
abstract organization of knowledge) way.
It also seems to me that Wells' approach also can be situated among a "text
mediational view" (Wertsch&Bivens, 1992) of CHAT. Therefore, far from a
"modelling interpretation" (Idem)
