The Math You Don't Learn is Harder Still

[twisting_edge]

Take heart. The situation is even worse here in Norway.

I would not have thought it possible, but you are right.

Note that these are just the math scores, below. The 2003 eighth grade science scores are also on that page, table 9.

From http://nces.ed.gov/pubs2005/timss03/tables.asp" (figures in table 3)

Yeah, it is extremely disheartening.
We have some insane individuals in positions of power who have been bent upon wrecking the Norwegian school (which was excellent in the early 80's).

The gurus on the faculty of pedagogics (they quarreled themselves to get their own faculty!) have, among other ideas, advocated the abolition of mathematics as a separate subject in school.
For example, maths should be "integrated" in other subjects like physical education. In all seriousness, a guru said that kids would learn maths better if they were to "calculate" the angle between the skis of an athlete climbing up a slope, rather than learning "abstract maths" like trigonometry.

The situation in Norway is quite horrifying.

That particular example doesn't sound too bad, since it is really just a word-problem. Those things were common even in the antediluvian days when I memorizing multiplication tables. It's sort of a non sequitur to suggest not teaching trigonometry, however, since that is how you would go about calculating the angle of the skis. So I assume the reality must be a bit worse than simply using word problems to integrate the subject matter.

Note that I didn't just memorize multiplication tables: I was fortunately on the cusp of a prior round of "old math" and "new math" debates. We were taught how to build our own multiplication tables before we were told we'd have to memorize the things even if we knew how to build them from scratch. "You're not always going to have time to work it out. You need to simply know the answers," I was told (and more than once, since I tended to protest rather loudly at the inanity of it several times).

Net result? I became good enough at building the things that people assumed I must have them memorized to do it so quickly. Whatever works, y'know?

No trig. involved, it is after all far more "practical" to use a half-disk with angles inscribed upon it than using dreary trig, isn't it?

"You're not always going to have time to work it out. You need to simply know the answers," I was told (and more than once, since I tended to protest rather loudly at the inanity of it several times).

It's true, though. Knowing how to do quick multiplication (or at least a quick estimate) in your head is really useful in the later years. You should know the technique for multiplying large numbers and memorize smaller numbers (1-10 at least).

Ever meet people who can't do those small multiplications? It's really kind of scary.

Even more so for calculus. As I wrote earlier in this topic

It's a lot like entry level calculus. Simply being able to solve the problem with sufficient thought isn't adequate. Being able to solve it almost without thinking is vital if you want to move beyond it. Yes, everyone knows you can derive the division rule from the multiplcation rule. But, as one of my professors said, "I don't care if you've taken five qualudes and passed out in a puddle of beer. If I roll you over and shout, 'Division!', I want you to tell me this," as he pointed at the board.

I meant to write "Division Rule" in the quote, but I missed that part. It should have been clear from context. Also, he smacked the board, he didn't just point at it. Moreover, it's correctly spelt "quaaludes".

It's even scarier when you try to buy something at a convenience store and the cash register has crapped out, and the clerk freaks. You buy gas (taxes computed at the pump), a non-taxable food item, and another item that has a 5% sales tax. You need to get to where you are going and can't wait for the register to get fixed (simple reset, likely) but you can't convince the clerk that it's OK to add 5% to the cost of the taxable item and then add the gas and the non-taxable item. How anybody can get through high school and not have this very low-level grasp of math is beyond me.

I really hope it's because they're not sure whether or not taxes apply to the given items. Well, more "wish" than "hope."

In my perfect world, everyone would know arithmetic and everyone would know OF higher mathematics (ie, that it's not arithmetic).
