If so, what was a model of their 1988 "cognitive apprenticeship" paper?
I think the actual roots of their cognitive apprenticeship at that moment
was mental models research and expert coaching system desgin.
They abandoned the dream of expert-help-system or expert coaching
system mabye at some point after 1986. However, in some sense,
the same kind of theoretical framework for learning was still remaining
in "cognitive apprenticeship" instructional design at least at the point
of 1988.
Around 1986 and after that in Palo Alto, especially IRL people were
exciting the view of apprenticeship and situated learning.
When I re-read papers such as Brown and others 10 years after
publised and excitment in IRL, I found out that I have many complains.
Probably now even Lave herself has many complains about her Situated
Learning book.
Regarding Brown and Duguit, they seem to change their view after
that as well although they do not directly criticize their own 10 years
ago paper.
Anyway, it is a history of the issue of apprenticeship I understand at this
moment, from a specific view in the process of workplace research.
