[Xmca-l] activity and Davydov

[Huw Lloyd]

Davydov's use of activity seems to be used in a way whereby the object of
activity is held constant (e.g. quantity in Problems of Developmental
Instruction, pp. 147-154).

I don't recall reading Davydov explaining this however.  My inference is
that it is the problems (contradictions) presented by the teacher that
establish this constant basis of activity, i.e. that the object of the
activity is given in terms of the problem.

Has this been documented anywhere?

Thanks,
Huw
