It's interesting to use an ethnic achievement gap as a legal basis for opposing a particular math program. That most United States school districts don't simply use Singapore Math

http://www.singaporemath.com/Primary_Math_s/21.htm

shows that most math curriculum adoptions are not made on the basis of best results for least expense.

yummyfajitas• 16 years ago

It's mainly convenience. In the educational establishment and some courts, equality is more important than quality. Challenging curricula on the basis "this is bad for non-asian minorities more than others" is more likely to be successful than "this is bad for everyone".

It is considered better for 100% of every group to be a moron than for 70% of blacks and 30% of whites to be a moron.

[Edit: Added words "it is considered" to last sentence. Before it looked like I endorsed this view, which I don't.]

This is probably because the program you repeatedly suggest as the solution to all of the math education woes in the US has a distinct lack of statistically valid studies to back up the claims being made. It is popular among the homeschooling crowd but that does not mean it is effective or applicable at a larger scale (e.g. the LA unified school district alone has three times as many students as Singapore but only twice the budget, etc.)

tokenadult2• 16 years ago

LA unified school district alone has three times as many students as Singapore but only twice the budget

That's an interesting factual claim, which depends crucially on currency conversions between the United States dollar and the Singapore dollar. Do you have a link to a source for the factual statement, preferably one that "shows the work" (as a math teacher would say) by giving the school-age population numbers for each place and the all-sources primary education budgets for each place?

From the article >>In this approach math is substantially dumbed down for "equity" reasons and students are asked to discover age-old principles on their own.

Charlotte Iserbyt, former Senior Policy Advisor in the Office of Educational Research and Improvement (OERI), U.S. Department of Education, wrote the free eBook (pdf) "The Deliberate Dumbing Down of America" http://www.deliberatedumbingdown.com/

"Dumbing down" and "discovering age-old principles on their own" are not necessarily the same. There is definitely value in learning to do creative work in math and science, beyond just rote memorization and learning to regurgitate what the teacher tells you. It pretty clear that many people with high grades in school are poorly prepared for situations where you actually have to do original work, like grad school. Of course, there has to be a balance between base skills and that.

Also, for another take on math education, see http://www.maa.org/devlin/devlin_03_08.html

> "Dumbing down" and "discovering age-old principles on their own" are not necessarily the same.

Indeed not. I'm writing an interpreter for a Lisp-like language right now (does Lisp count as "age-old"? I guess in computer terms it does), but I don't consider that a dumb thing to do.

bitwize2• 16 years ago

The problem with rote memorization is that it gets results. You cannot do algebra until you know your times tables by heart, and how did kids learn their times tables in ages past, when men were men and went to the moon without the aid of calculators? Drill, drill, drill.

Going on and on about the beauty of math is all well and good if your brain is wired that way, but when 90% of America's high school grads are stymied by making simple change, you fall back on what works.

lutorm5• 16 years ago

I looked at that link. I admit that I only read the preface, but when I got to this passage:

America’s transition from a sovereign constitutional republic to a socialist democracy would not come about through warfare (bullets and tanks) but through the implementation and installation of the system” in all areas of government—federal, state and local. The brainwashing for acceptance of the “system’s” control would take place in the school—through indoctrination and the use of behavior modification...",

I gave up.

American schools may be many things, but only the delusional can claim that they are a plot to socialism. They do have a certain totalitarian bent compared to the schools I remember, for sure, but I'm not sure what that has to do with social democracy...

There is also a certain irony in the fact that the schools in "socialist democracies", by which I assume they mean countries like Sweden, consistently show better results than their American counterparts. I'm not sure how the "system" would think that dumbing down the school system will help them achieve that.

iterationx2• 16 years ago

Why would you admit to only reading the preface? If you don't want to read the book fine with me, but don't pretend like you have some useful input.

anigbrowl6• 16 years ago

Ms Iserbyt, according to her bio at that same website, is also 'best known for her 1985 booklet Back to Basics Reform or OBE: Skinnerian International Curriculum and her 1989 pamphlet Soviets in the Classroom: America's Latest Education Fad which covered the details of the U.S.-Soviet and Carnegie-Soviet Education Agreements which remain in effect to this day.'

Now, while I'm no lover of teacher's unions or abandonment o tried and tested instructional methods, her suggestion that american pedagogy is a communist plot is itself an example of 'dumbing down'. I'm reading her e-book, and it's little more than bad polemic, absolutely riddled with logical fallacies and cheap rhetorical gimmicks. Sophistry is unfortunately not confined to one end of the political spectrum.

Afton• 16 years ago

I am made uneasy about someone that contrasts 'low income' and 'white' in their graphs.

I do however, still holding a low opinion of the discovery math pedagogical model in general, as it requires more math sophistication than is likely to be found in an elementary/middle/high school's teacher.

jff3• 16 years ago

I was disturbed by the "low income" vs. "white" separation. Does the white group also include low income white students? Or, to further their point, did they decide low income whites aren't really white?

Nobody should have to "rediscover" the Pythagorean Theorem. I'll go out on a limb and say Newton, Leibniz, Einstein, Descartes, etc. just went ahead and read Euclid, and they did pretty well for themselves.

lutorm5• 16 years ago

Learning to prove mathematical theorems is an important skill in mathematics. If you only learn to use what comes served on a silver platter, where will you learn to handle situations where you haven't had the theorem taught to you in advance? My impression of UC undergraduate students is that "find the correct formula and plug in the numbers" is the only type of math they know how to do, and encouraging that doesn't seem like a way forward.

jules• 16 years ago

I agree that kids should not have to discover the Pythagorean Theorem. But the way it is now isn't good either. Kids are just told to memorize lists of mathematical facts and taught how to apply these facts to solve math problems. This is supposedly more useful than learning why the facts are true.

mquander• 16 years ago

Well, they should have to discover something. There aren't a lot of undiscovered results that are accessible to an elementary school student studying math, so that discovery will usually be a rediscovery.

Is it foolish to write an interpreter as a pedagogical exercise because someone has written a better one?

tierack• 16 years ago

Typically, this sort of pattern means that "low income" includes low income students across all races, that's the only selection criterion for that group. The "white" group will include all white students (including low-income), and the "black" group will include all black students (including high-income). Nothing nefarious.

olegk4• 16 years ago

Welfare. These low-income and minority kids know they won't starve to death, they think that learning is "acting white". Here's the result.

Oh well, better for the rest of us.

lonestar• 16 years ago

"Oh well, better for the rest of us."

Do you really think so? I'd prefer to live in a society where everyone was well-educated, or at least enjoyed learning.

I think you'd find there is some spillover benefit for yourself to be had from "these low-income and minority kids" receiving high-quality education.

olegk4• 16 years ago

I'd prefer to live in the society where all people would have unlimited supply of food, water, heath care, wouldn't kill each other, have lots of fun.

Unfortunately this kind of "magical" thinking is a very weak argument, and just doesn't work.

Welcome to the real world.

anigbrowl6• 16 years ago

I dispute this assertion. When I was growing up, Ireland was ethnically homogenous with poor economic security and hostility to welfare cases like those of single mothers (for religious reasons), but there was still a distribution of ability and academic application. there were poor kids that studied hard and rich kids that didn't give a fuck, though more of the former than the latter, since high schools there employ streaming. You need more evidence for this assertion that the existence of welfare automatically results in poor academic outcomes.

I suggest that the disparity of result may have always existed, but in the past there were fewer women in the workforce and more jobs in manual labor such as manufacturing etc., so that a lack of academic achievement didn't necessarily result in economic insecurity.

olegk4• 16 years ago

Ireland is very white. So there's no "acting white" problem.

cabalamat3• 16 years ago

Finland has more of a welfare state than the USA. Finland also has better school achievement.

WestSeattleDan2• 16 years ago

Minnesota has better school achievement than the USA. There must be something to Northern latitude icy winters producing improved academic achievement. Canada is also better than USA in math. Maybe not using the $100 million NSF grant created math books and a few other publisher clones of same has a positive effect.

danteembermage• 16 years ago

As a university level instructor, I find so many things high school teachers have to put up with appalling. I choose my text book for one. My lesson plans are not approved by anyone except me (yes, in fact my sister-in-law had to use recycled old lesson plans because they were "AP approved") The decision rights should be located as close to the in-the-trenches information unless the coordination benefits outweigh the costs. I doubt the benefits come anywhere close here.

anigbrowl6• 16 years ago

A pity that the article does not include any excerpts from the books or detailed critiques of what's wrong with them.

Examining a Discovering Algebra book at http://www.amazon.com/Discovering-Algebra-Investigative-Appr... suggests that the book is not so bad (though obviously this only allows previewing a few pages)...however, I'm unsure whether this is even the same book, since the OP doesn't mention the name of the publisher.

It's hard to judge whether the books themselves are poor or whether the failure stems from teachers unwilling to adapt to a knowledge-building rather than a purely didactic approach. Education is important and worth spending money on but (as a European) I'm frequently horrified by American teachers, whose union seems defensive even of members who exhibit basic deficiencies in literacy or numeracy. It's still strange to me, for example, to consider that there are teacher's editions of textbooks that include answer keys for scoring homework - I ask myself what possible need a competent teacher could have for such a thing, and why school districts are wasting money on buying them.

I'm strongly against dumbing down school curricula; on the other hand, I think discovery of knowledge by experiment imprints knowledge far better than mere receptive learning (cf. recent HN posts about college physics students who learn the material well but are hopelessly incapable of applying it to a novel context). So I'm inclined to favor the approach of these textbooks (without endorsing their actual content). This article http://www.oregonlive.com/news/index.ssf/2009/01/the_constan... suggests that at least some of the problem stems from parental or school unfamiliarity with the methods, such as complaints about an 'overemphasis on...problem solving'.

Hmmm. I think we need to take a closer look before jumping onto the 'blame the book' bandwagon. The books discussed may well be inadequate, but it's hard to judge that without a more reasoned critique. If anything, this lends further support to opinion of many HN readers that we should be moving towards open-source textbooks instead of the current cosy arrangement between school districts and publishers.

tylerritchie2• 16 years ago

It's the books and the curriculum. Just watch http://www.youtube.com/watch?v=Tr1qee-bTZI and cry.

flatline2• 16 years ago

It's funny, I do those "cluster problems" in my head to solve most multiplication and division problems...I presume that I invented the method myself at some point during basic education, as these books are encouraging kids to do. The standard algorithms are great on paper but suck to do in your head for anything very complex (at least for me...)

I can see the point though about disadvantaged kids having trouble with this. If someone is struggling and does not have good parental support, it would be hard to learn basic math skills reliably this way. Rote memorization of methods and figures is useful at pretty much all levels of math, and if you just want kids to be able to multiply two numbers, drilling them on one method makes a lot more sense than trying to create young mathematicians.

WestSeattleDan2• 16 years ago

Try looking at a comparison of Discovering Algebra and Prentice Hall Algebra Here: http://www.mathunderground.net/PHvsDA/PHvsDA.html great ready to cry large tears.

scott_s• 16 years ago

Eek ~8-0

Gotta side with the OP on this one, thanks for the link. It's not the math that's at fault so much as the total orientation towards grinding out the answer with a calculator, vs writing it. Oh dear :-/

tsally• 16 years ago

If you want an example of math education that does a lot right, take a look at what's been done in Chicago [1,2]. Unfortunately, substandard K-12 curriculum is all too common. I don't even want to think about the billions of dollars society would save by implementing effective programs across the board. Makes me sad. :-/

Groxx3• 16 years ago

I find it telling that the article breaks down scores by race, not by income. Note that it claims that the difficulties are for low income families who cannot afford tutors / other resources, not black children. What's the crossover? What's the pass ratio for poor white children?

Granted, a book can easily be harder to read / understand for less-classically-trained children. I'm not saying it's not possible, just that the article is definitely seeing what it was looking for.

abscondment2• 16 years ago

The first table cites the pass ratios for all low-income students at 37.3%, 28.3%, and 26.4% for 4th, 7th, and 10th grade respectively -- the pass rates for black children are lower than that. So one can accurately infer that non-black low-income children perform better.

Granted, this isn't as informative as breaking things down by both race and income. But, as far as I can tell, this is a limitation of the state's reporting data and not a selective argument made by the blog.

See http://reportcard.ospi.k12.wa.us

Groxx3• 16 years ago

Maybe I'm just missing something, but I see no data there about pass ratios for any subject, much less a breakdown by race / income.

cabalamat3• 16 years ago

I'm sure some methods of teaching maths are better than others. But is a lawsuit really the best way to settle the issue?

houseabsolute• 16 years ago

OK, so it worsens the achievement gap, but what about absolute achievement. I'm fine if the poor are even worse off than the rich if they are 5% better off absolutely (i.e. the rich are 10% better off).

motters• 16 years ago

The categorisation of children's test scores into different racial types I think says a lot about how far America has yet to go in dealing with issues of segregation and unequal opportunities - despite Obama's election as president.

curtis2• 16 years ago

We've been doing this categorization for a long time, and if we don't do it, we can't tell if we're really addressing the problem.

Scott_MacGregor• 16 years ago

Why not offer both types of instruction and let the teachers recommend which students should learn by which method. It seems like having an option would make it more likely more students would do better. Why limit the students to only one option.

A Mathematician’s Lament by Paul Lockhart: http://www.maa.org/devlin/LockhartsLament.pdf

Persuaded me that the way I learned math is pathologically soul crushing; the way it's taught from kindergarden through university. The first two pages set up a nice metaphor: mathematics is argument and creativity and our traditional math education by memorization and rote repetition are akin to teaching music by reading and writing sheet music without first hearing or playing an instrument.

"No society would ever reduce such a beautiful and meaningful art form to something so mindless and trivial; no culture could be so cruel to its children as to deprive them of such a natural, satisfying means of human expression."

The rest of the article digs into some specific examples.

Mathematics instruction needs an overhaul and back-to-basics isn't The Right Thing.
