Re: [xmca] Mary Had a Little Lamb: the concept categories



David,

I was referring not the line from 16.2 to 65.5, which is correctly placed, but the line that extends from 81.3 to the upper-right corner. That should run from 79.5, I think. The fault isn't Minick's, for the diagram is the same in the Spanish translation.  

I just reread the section (5) where LV is comparing learning scientific concepts with learning a second language. After identifying in detail three-plus considerations for exploring the analogy he warns that it should not be extended too far. He argues that with a new language one doesn't learn a "new system of meanings", but when learning a scientific concept one does. I would expect that you would disagree with this, and it seems to me that as I'm learning Spanish (painfully slowly) a new system of meanings is indeed becoming evident.

I suppose that what he's emphasizing is that with EC there is no *system*, while with SC there is (OK, "AC", i.e. academic concepts if you prefer - but that's precisely because you see it as a way of talking, no?). But one could argue that with one's native language there is really no true "system" of meaning either. But now I'm off into the depths of #6 to see how he defines a system.

We think that precisely this kind of pressure on grammatical processing (particularly with written language) would eventually lead to hypotaxis (i.e. "because" and "although" in preferance to "so" and "but"), a characteristic more typical of academic than of everyday language.

Not too surprising, given that we are looking at microgenesis and not ontogenesis, and given the lack of cramming given the kids. But still it's the opposite of what Vygotsky found.

> That helps, thank you. Part of my confusion was due to the fact that the figure in this chapter (it's on page 214 of the Minick translation) is evidently misdrawn. As shown, "hypothetical" extensions are drawn back in time for both SC and EC for "Because" questions (the upper lines), but the hypothetical extensions drawn *forward* in time (the lower lines) are of EC for "Because" and of SC for "Although." What should have been shown are the extensions forward of SC and EC for "Although," because if this were done, we would have a parallelogram for each question.

This makes sense to me; it is much more difficult than "because", since it contains the dialectical idea of two things that are linked but distinct and in some sense opposed and contradictory, not simply the idea that they are linked but distinct and one follows causally from the other. It's hard to get your head around that one.

>> A question on chapter 6 of R&L. Vygotsky provides some data on the first few pages, which I plotted (attached) and found that I had reproduced his own diagram later in the chapter. This is from the study asking children to complete sentences with 'because' or 'although,' using either everyday concepts (EC) or scientific concepts (SC). LSV interprets the data as showing that responses employing SCs are always at a higher level, but that with time they 'pull up' the ECs. The first figure does seem to show this. It shows results from asking the children "Because..." qustions. At 2nd grade the SC results are higher than the EC results, while at 4th grade although the responses using SC are scored even higher, those using EC have caught up. But in the second diagram, showing data from "Although..." questions, the gap between SC and EC grows over time/age/grade. The difference between SC and EC is greater at 4th grade than at 2nd grade. This seems to run
