If the 'math education system' cannot deliver that much, then the system has failed (IMHO).
I really am not too worried about whether it's arithmetic or geometry or algebra, about whether the student is 'mathy' or otherwise.
An effective 'math education system' should be able to ensure that the majority of its students do not come out of school 'fearing and loathing' math (or "math lessons").
As stated earlier, I am NOT a teacher at any level and I do not plan to be one (except for showing people how to apply the 'One Page Management System' (OPMS) to issues of concern to them. The concern could be "To ensure that my students do not leave school 'fearing and loathing' math". Doing that, I claim they would most probably also be in a position to ensure that those students acquire at least 'adequate' proficiency in arithmetic, geometry, algebra, or whatever is to be included in that "3rd R". > > I stated earlier that we can and should expect every > student to be successful with arithmetic and > fractions.

If so, the fact that 'most students fear and/or loathe math by the time they pass out from school' is clear evidence, to my mind, that the 'math education system' has failed (and this failure is a whole lot more serious then the failures of the students in math). . And I do believe that we should at least work on overcoming that 'fear and loathing'. All else that's needed for math education would probably follow in a very natural way. > > least get them through arithmetic and fractions. I am > pretty certain I can.

This is, I believe, often a characteristic error made by those who 'came to math' via engineering. (I myself am one such, and for quite some time I had believed that 'mathematical thinking' really started with algebra).
As a matter of fact, I believe there is much sound and tested scientific evidence for the view that true 'mathematical thinking' is actually seen in/ demonstrated by a learner when he/she studies geometry, or patterns perceived in nature, or symmetries seen in many of the objects (natural and humanmade) around him/ her, or even when he/she as an infant studies his/her fingers with some profound questions in the mind (about which science as of today knows very little indeed!) I believe  but am unable to provide clearcut evidence  that 'mathematical thinking' may well be demonstrated by human children almost from the time they are born, when they open their eyes, and so on.
This is an area that may well be worth exploring, but I lack the needed background in human psychology and cognition to justify such ideas  and it would probably take me far away from my prime interest, OPMS.
I'm afraid I don't quite 'get' most of your argument in your abovequoted paragraph. I observe that this is NOT on account of my not having studied ('American') English poetry  I do assure you that I'm pretty well able to follow the subtleties of most argument put forth in English (any variant of it)  except when it's argued ineffectively. In any case, I believe much of whatever argument is contained within that would be for teachers to agree with or argue against.

I on the other hand would tend to believe that a student 'who likes a thing' may well be most interested to *do* something with what he/she has learned. i believe this is an unsubstantiated generalisation of yours. > >I think that is > the only version of *like* that can get a student > through algebra and leave them *owning* it in the > end.

(Sent off in a rush, as I have to conduct a quick OPMS workshop for a visitor who is leaving town tonight, therefore, E&OE).
