Coryoth writes "The BBC is reporting on a recent study in the UK that found that the difficulty of high school level math exams has declined. The study looked at mathematics from 1951 through to the present and found that, after remaining roughly constant through the 1970s and 1980s, the difficulty of high school math exams dropped precipitously starting in the early 1990s. A comparison of exams is provided in the appendix of the study. Are other countries, such as the US, noticing a similar decline in mathematics standards?" Readers with kids in school right now may have the best perspective on changes in both teaching and testing methods -- what have you noticed?

Pay teachers more (Score:5, Insightful)
We've noticed this 'dumbing down' (thanks Idiocracy) for a while now at Uni. The newer mathematics students enrolling in first year are lacking some of the basic skills. Example: a couple of years ago, trigonometric functions and identities were completely removed from the high school syllabus. It goes back all the way to year one at school.
I don't think teachers are being paid enough and they are certainly not valued enough by the community. Once upon a time, the best and brightest minds went into the teaching profession; it had respect and was highly valued. Now, it's whoever wants to become one, winner by default. The best and brightest need to be attracted back. Why would somebody who has the ability to earn more than four times the national average wage go into a job that earns less than the average wage?

The caveat is that you frequently have to go to grad school to be qualified to teach, and grad school prices are rising much faster than public school salaries. Of course housing prices and food prices are also rising faster than salaries. Every career that used to be "just enough to get by" is in danger of falling out of the bottom of the middle class. When you have something like modern public school teaching, where most of the potential creativity and chance to influence young intellects has been replaced with neck deep bureaucracy and a focus on preparing for the next evaluation test, there isn't even a "contribute to the community" sliver lining any more. Public schools in America are broken.

You are evaluating the work teachers do based on your experiences as a student.
When class is in session, I work far more hours a week than my software development friends. Basically, I can't play when school is in session. There literally is no end to what needs to be done.
When class is not in session, I can scale back to about 40 hours a week.
I'm so sure you think that just because students aren't at the school, teachers have nothing to do (eyeroll).
Part of the reason it's hard to get good people to teach is that it's an abusive amount of work for very little pay.
I only taught at the K-12 level for 2 years before I said "screw this." I'm at the uni level now, and while the hours don't go down much, the pay goes up a lot. Also, you don't have to deal with parents!

Slashdotters are an anomaly because our careers and interests require us to do maths all the time. If the future historians are allowed to slack off on their trig tests, so what? They weren't going to be engineers anyway.

Calculators on tests have made tests easier, but this is a good thing. Can you imagine having to figure out sines and cosines by hand anymore? What calculators do is make it easier to get to more advanced topics. Knowing how to add 1234+2345 in my head is just no longer a necessary skill. I rather students practice the properties of math, and write things out on paper anyway. (#1 problem with algebra and calculus students, they try to do too much math in their head) Calculators are not going away any time soon, and anything that encourages the entire population to do more math is a good thing in my book.
Secondly, while historians may not need to know trig, it is imperative that as a nation we raise our mathematical abilities. Great math and science students generally did not learn everything at school. Having a parent that can help out with some algebra homework (or even better understands the value of math) will make it much MUCH more likely that the child will grow up with an appreciation of mathematics. If we as a human race want to push the maths and sciences as far as we can, then we much raise the math and science ability of the entire population.
Just so everyone knows where my loyalties lie, I am a mathematics major, I am a math tutor, and hopefully eventually you'll see me teaching mathematics at a University near you!

Take an equilateral triangle of side length 2. Cut in half, so you have hypotenuse length 2, base length 1, and vertical length sqrt(3). Now you can find the cosines and sines of both 30 and 60 degrees (or pi/6 and pi/3 radians, respectively).
Now take a right angle triangle with base and vertical length 1, and hypotenuse length sqrt(2). Now you can find the sine and cosine of 45 degrees (pi/4).
So with a few simple skills: basic geometry, SOHCAHTOA, Pythagoras's theorem, you can find the sine and cosine of 3 different angles. Now learn your CAST rule (where the different trig functions are positive based on the quadrant) and you can do it for up to 12 different angles. Then learn your double angle formulas and you've got another 4 angles. Then learn the period of trig functions and you can now find it for any of those 16 angles plus the period of the function. Anything other than that, and yes, you'll need a calculator, but knowing those rules (which can be taught progressively throughout high school) and you'll find doing certain things much easier. Now, granted, trig isn't for everyone. However, it's not unreasonable to expect people to do certain calculations sans calculator. Like multiplication, addition, and division.

There is a difference between testing knowledge of the subject matter, and giving the test taker a hard time. A "difficult" question might be great to ponder when you have unlimited time, but in a time pressured test, it is not appropriate.
Maths has changed / evolved... (Score:5, Interesting)
Maths in the 1950s was designed for engineers and scientists in that generation. They learned what they needed.
Maths today is exactly the same. The fact is you can't use 1950s standards to evaluate today's exams any more than you can use today's standards to evaluate 1950s exams.
The only real question is - Are engineers and scientists finding their maths education weak?
The answer in my view is no in most cases. In a limited number of careers the maths they received isn't nearly advanced enough but that would have been the case in the 1950s too.
As I said they're using the wrong measuring stick to measure the difficulty of exams. Nobody needs to know half of the useless junk that kids learned in the 1950s when frankly it is less time consuming and more accurate to use a calculator.
That's just my opinion. I honestly think a lot of this kind of "research" is a result of much older people looking at today's maths and thinking "Why aren't they learning what I did?" While completely ignoring what they're learning that the 1950s students didn't.
Re:Maths has changed / evolved... (Score:5, Interesting)
Absolutely. An engineer in the 40s/50s would need to have in-depth critical skills of geometrical proofs and relationships, nasty algebraic manipulations, and "bag of tricks" mathematics like series approximations, dummy variable substitutions, etc, because computing resources were rare and resource intensive. If you look at the older tests linked in the OP, you can really see a reflection of that need.
As an engineer today however, I have zero need for knowing trig simplification identities, calculus proofs, and the like beyond a high conceptual level, but I have far more need and usage of logical and discrete math fields, programming concepts, vector operations, statistical methods, and other "math" topics that are still completely absent from any high-school math curricula that I've seen.
My wife (a math degree and former teacher) suggested throwing out the "calculus path" of mathematics entirely and retool math education to a "discrete math path". It sounded heretical to me initially, but I've come to believe that she's correct.

And I'm afraid that you are, indeed, a victim. You see, the reason why you learn geometric proofs and calculus proofs is to assist with developing problem-solving skills that require an individual to reason a problem from start to finish, much like real life. It scares me that you claim, as an engineer, that all you need to know are the rote mechanics of math (and yes, that is what you describe: number crunching as opposed to critical problem analysis).
Unfortunately, at least in the US, proofs of any type are becoming rare to non-existent in many curricula. I see the direct result of this every day I'm in school and a student stares at me with a blank look on his/her face when I ask him/her to analyze and determine the best course of action for solving for some quantity X given Y and Z.
You didn't mention what type of engineer you are. Computer/software/hardware, perhaps? Then yes, I'd agree that programming logic, vector operations, and the like are probably a valuable intellectual commodity. But I know many engineers who work day in and day out designing things, and this takes more than a simplistic knowledge of how to perform statistical computations.

No. Students seem have this sense of inevitability. They are still of the belief that they don't have to. After all anything else they complain about in school gets changed. I don't see their attitudes as defeatism, its entitlement that they suffer. They don't have to do this, that, or what not. We don't have the right culture in schools, especially city schools among minority students. Until we change the fabric of society the MTV generations will forever think themselves above "working hard".

We gave up control of our schools to "feel gooders". Now its all about grief counselors and no winners allowed because no one should be a loser. When we removed the reward of success what did we expect? I have seen articles where every student got to walk the diploma line regardless if they graduated just so they didn't feel ostracized. Well tough shit. Your boss ain't going to worry about making a failure to feel good. If you don't perform your in for a world of hurt. I guess you could go into government work, of all categories in the job market they have added more jobs than anyone and everyone knows the saying about how its near impossible to lose a government job.
Schools and students are simply trying to cheat the system. The problem is the schools encourage it because they don't allow for losers. They don't want to hurt little Bobby's feelings so they set him up to fail in life. If they want control of our kids then they should be responsible for them. They get hell bent if someone raises a finger about the Bible in school or complains about sex education yet they are completely aloof when it comes to holding the kids to a standard of education.
Private school was the only recourse I found. Standards had to be met or we might not be allowed to come back. Students were encouraged to be better. I don't see that outside of a few select public schools; you know I hear it all the time how so and so's public school isn't like those others but sorry it is.

When I went through the Ontario system (1986), the requirement for engineering was 3 high schoool math courses in: Calculus, Algebra, and "Functions and Relations".
I did some Calculus T.A. work, and the new students are missing certain critical concepts. The new curriculum has eliminated Integration from High School Calculus. It is actually lucky that the students get any Calculus in High School at all. One of the original proposals for the new curriculum recommended eliminating Calculus entirely. The Engineering schools fought hard to keep Calculus in High School.
Some of the first year engineering students have not seen key trignometric functions like the sine function. Other students have not seen Sigma notation, which is used for for finite and infinite series. Almost all of the students struggle with the university Algebra course, which makes me suspect the high school introduction to vectors and matrix algebra was been watered down.
Reducing the high school requirement from three to two high school math courses hurts the undergraduate engineering students. Further, a subject like Calculus benefits from repeat exposures over a number of years. The students would benefit from an introductory Calculus course in Grade 11, a deeper course in Grade 12, and then the 4 more courses in first and second year university. That way, the students have had 4 years Calculus experience before they need to apply the hard stuff in 3rd and 4th year engineering. As it is, students might only see Calculus for 2 years at university, and I'm not sure if this is enough time to really absorb the subject.
As for the quality of the students themselves, the students from the new curriculum are different. They are very fast (faster than me) at solving problems with known forms. On structured problems, similar to ones they have seen before, they are very fast. Unfortunately, they are very poor at solving unstructured problems, and problems where they have not seen the solution technique in advance. It is like someone has beaten the creativity out of the students. They can write tests really well, but they can't do original math. I imagine the students will pick up the creativity as they gain experience. It is just that someone has removed the fun advanced questions that really get the students thinking from the curriculum. The high schools are somehow creating students that can do simple stuff, but lack deeper insights into what they are doing. The students haven't been allowed to try, fail, and sometimes succeed at solving the harder mathemetical questions.
