Re: [xmca] Numbers - Natural or Real?



As usual, when I haven't been following a thread, I don't want to butt in.

But ... the account of counting reminded me of discussion by Walkerdine that might be of interest. It's on pp. 67-68 in Walkerdine, V. (1997). Redefining the Subject in Situated Cognition Theory. In D. Kirshner & J. A. Whitson (Eds.), _Situated cognition: social, semiotic, and psychological perspectives_ (pp. 57-70). Mahwah, N.J.: L. Erlbaum.
(One reason I remember this passage is that the silhouette of 5 people 
holding hands, which you can see at
http://www.amazon.com/Situated-Cognition-Semiotic-Psychological-Perspectives/dp/0805820388/
only if you click on the image to get an enlarged view, is taken from an illustration for my discussion of these Walkerdine examples, in my chapter of the same book (at p. 111).) I hadn't made the connection before, but the argument in my "Silhouette" paper in _Semiotica_ is actually germaine to the argument that Walkerdine makes with her examples here.
Anyway, here is the Walkerdine:

[67] As Lave demonstrated, not only do calculations within shopping and other practices exist in a different way than in school, but the calculation is often not the purpose of the exercise. In my work examining home and school practices involving calculation, the significant transformation occurred to make the task mathematical only when calculation became the target of the exercise. In home practices, this was rarely the case.
Cooking practices at home had a cooking product as their aim.
When a calculation became the focus, certain semiotic shifts occurred. In several examples of exchanges between mothers and daughters that I analyzed, the mothers made certain discursive shifts when the focus of the task moved from cooking to calculation as a product. These shifts reoriented the focus of the task so that, as in school, the making of cakes or some other practical task was no longer the product.
The product is the production of the counting string, an addition sum, or 
whatever. To accomplish this shift, in the examples that I analyzed, the 
mothers helped their daughters produce the move by the use of semiotic 
chains in which new signs were constantly formed. For example, one mother 
got her daughter to name people they were pouring drinks for and to work 
out how many drinks by holding up one finger to correspond with each name.
This is the first relation of signifier to signified. In this case, we 
might describe the names as signifiers that are attached to signifieds, 
the people to which they refer. But here they have dropped to the level of 
signifieds to be united with new signifiers, in this case iconic 
signifiers, the fingers.
The next stage, which is not reached by this mother?daughter pair but is 
by another, is for the fingers to drop to the level of signifieds to be 
united with new signifiers, in this case spoken numerals. By this time, 
any reference to people outside the counting string no longer exists 
within the statement. In this case, the mother goes on to get the daughter 
to unite fingers and numerals in small addition tasks of the form: "Five 
and one more is . . ."
[68] I argued that discursive shifts such as this were central to the 
accomplishment of the discursive transformation and to the repositioning 
of the subject it entails. Statements of the form of "five and one more is 
. . ." can refer to anything. All external reference and metaphoric 
relations are excluded from the string. They create a discourse in which 
there is no I, except an omniscient one (the God of mathematics) which can 
describe the world as a book written in mathematics. I therefore argued 
that discursive shifts, basic as they are in this case, produce the 
possibility of huge shifts of subjectification and the production of the 
man of reason, because for Lacan at least, semiotic chains are carried 
along the metaphoric axis, and this no longer exists in school mathematics 
discourse.
In Lacan's analysis of unconscious processes, a signifier can drop to the 
level of the signified and a new signifier/signified pair can be formed. 
This is what Lacan meant by a semiotic chain. In examples such as these, 
such chains form a bridge between one practice and another.

David, you cast doubt on the ancient idea that mathematics is the science of quantity and said that Vygotsky was clear on this. If Vygotsky is so clear, then you wouldn't need to go to an English translation of an Italian translation to find Vygotsky refuting the idea that mathematics is the science of quantity. But your re-translation doesn't say this anyway. The colon was a typo.
-----------------

But let's take up the interesting point you raise anyway, even though it does not say what you claimed it said, it is nonetheless interesting and pertinent.
Am I right here? A child learns to survey the perceptual field and point to 
things one after another reciting "one," "two,"three," ... and then remember 
the number they say as they complete the practice. This is called "counting." 
And I think it is a way children learn to abstract the units from a 
collection in their perceptual field - pointing to each ion turn and saying 
the next number. So I think they don't first abstract the actual objects and 
then abstract number from this. Learning the practice of counting is how they 
learn to abstract units from a whole.
Now, and this is the wonderful thing I learnt from Anna. Just because the 
last number I said on completing counting wa "Five!" does not mean that I 
know that there are 5 things. In fact, "Five" is a property of my counting 
action; but I have to be taught to see "5" as a *property of the collection 
of actual things*. AND then I have to learn that "5" is a *quantity* (a 
cardinal as well as the last ordinal).
So there are two big conceptual leaps involved *after *I learn to abstract 
things *by counting* them, before I get to the concept of quantity ... and 
the beginnings of a type of mathematics (since other types of mathematics 
will grow from other types of quantity).
So Bill, I think the position may be this (and please, I am way out of my 
comfort zone here, but the July 4 holiday will be over soon and maybe the 
cavalry will come to our rescue.) Your kids can't see any 2s in the 5 of 54, 
because they see the 5 as an ordinal. They can see 2 2s in 4, because they 
have been told so countless times, But they haven't been able to generalise 
that knowledge because 5 does not "contain" 4, it is just the number "after" 
4. OK? What do you think? Does that make sense?

I don't understand this, Andy. The short answer is "Sure".
What is YOUR short answer supposed to mean? In particular, what does the colon mean? I'm afraid the emoticons that we use in Korea are a little different.
