[Xmca-l] Re: In defense of Vygotsky [[The fallacy of word-meaning]

       The paper seems to be about unifying mathematics education research. Parts are a bit open to debate (especially arguments concerning the 'nature' of mathematics) and Ernest tends to somewhat gloss over this. However that is not relevant and you are correct Ernest does, among other things, put forth a unit of analysis for mathematics teaching which, as he admits is simplified for the purposes of the paper; i.e. the usual triad of teacher, student, and text (which is hardly unique to Ernest as he notes). At this point I have a question that I've been pondering about concerning such triads and their elaborations (and this goes back in a sense to things Schwab said elsewhere - the Schwab he quotes in the beginning of his paper) and, as he quotes you heavily, I will ask you: If this triad is indeed a prototype of mathematics teaching (i.e. posses all the basic characteristics of the whole), what makes this a prototype of mathematics teaching and not a prototype of, say, the teaching of reading? This is not a spurious question since, as a mathematics educator (of the type that Ernest wishes to unify - smile), I often find myself needing to help elementary school teachers realize there are actually substantial and observable differences (and substantial similarities) between teaching reading and teaching mathematics and, for sundry reasons, they tend to favor something like the former and cause their students some anguish in the learning of mathematics as time passes. Hmm, I guess I am asking whether the unit of the analysis can, in effect, be the 'world' or should it be, so to speak, among the 'minimum' relevant prototypes. It seems that it would be somewhat worthless otherwise (again similarities are important).

I wonder if there is a problem with Davydov's approach, in that it requires a specification of the final form of the mathematics to be learnt (a closed curriculum). But let me try: One candidate might be the 'reasoned justification for a mathematical use/application to our project' ... Implies meaningful verbal thought/interaction, and collective mathematical activity with others. Not sure how this works to define your curriculum content etc.
