Are You Better At Math Than a 4th (or 10th) Grader?

New submitter newslash.formatb points to this Washington Post blog post, which "discusses the National Assessment of Educational Progress test (specifically, the math part). One of the school board members took it and was unable to answer any of the 60 math questions, though he guessed correctly on 10 of them. He then goes on to claim that the math isn't relevant to many people. P.S. — if you want to feel like Einstein, check out some sample questions." Maybe this is mostly about the kind of life skills that are sufficient to succeed in management.

      Actually, a calculator is a hindrance. One of the virtues of mental arithmetic is that one gets a "feel" for numbers and magnitudes, and how they behave. People who use calculators exclusively never learn that skill.

      It's like putting people in a motorized wheelchair so they never learn to walk. In theory it's not a bad idea - a wheelchair with a powerful motor would give us the ability to drive around faster than we can walk or run, and carry lots of luggage around etc. In practice it's a stupid idea, obviously.

      What you should have done in that one problem was not used a calculator, but looked at the sizes of the numbers given in the multiple choices, and then picked the choice where the magnitude was in the correct ballpark.

      Uh, no. If a test question says I can use a calculator, I'm using a calculator. For some of these tests, there's too many questions not to. Obviously, this one was trivial, but you catch my drift. In *most* cases, a calculator is more efficient (yes, you can find some edge cases where realizing the "trick" is faster than typing the equation)

    After reading this article, having someone as influential as a school board member take this test and fail it is putting education on a very dangerous course. It normally wouldn't be too bad but this guy's ego is so big that instead of admitting that he just isn't knowledgeable on the subject, he goes on a rant about how irrelevant this stuff is to life and how unnecessary this subject matter is to evaluating a student's college career. I mean sure, it might not be relevant to him for his job duties, but any science/engineering discipline should be well versed in simple math like this. I really hope he doesn't make a push to dumb down these tests to make the math easier.

      People who fail at such tests are not functional in society : they cannot understand the basics of employment, either as an employer or an employee. They should barred from contracting loans as they have no way of understanding what an interest rate is.

      Reading comprehension fail. Note that the grandparent post says "any science/engineering discipline should be well versed in simple math like this." It doesn't say, "answering multiple choice questions." So, to spell out the difference for you, since you seem to not understand it--the format in which the student is tested for proficiency in mathematics is distinct from the knowledge of concepts and skills required for mastery.

      And yes, the grandparent post is correct. Any scientist or engineer should be able to demonstrate proficiency with these basic mathematical concepts (arithmetic, estimation, decimal numbers, rates, the Cartesian coordinate system, basic probability). In fact, I would say that ANY adult who has graduated high school should know how to do these things, for what would have been the point of attending high school in the first place if one so easily forgets such things?

      Here's the thing. We can debate at length about the utility of such knowledge for the vast majority of people in this world who would presumably not need to know how to do math to succeed or even get by in their day-to-day existence. But why is it that this is the measure by which we determine whether something is worthwhile to know and understand? If that's the way we begin the conversation--i.e., "will I ever need to use this?"--then we've already lost the fight to educate subsequent generations. It's a regressive, know-nothing, anti-intellectual attitude that fails to appreciate the value of knowledge for its own sake. It's why American society is so troubled--large segments of the American public have lost the ability to think critically, having become too accustomed to the notion that someone else will do the analysis for them.

    Assuming all questions had four options and the answers were uniformly distributed, then yes, the "expected value" is 15. But, surely you recall that the standard deviation of the binomial distribution is sqrt(60*(1/4)*(3/4)) = sqrt(11.25) = approx 3.35. So to get 10 puts you less than 1.5 stdev from the mean. For normally distributed data (which I would expect the scores for such a test with random answer selection), 68% of the results are within 1 stdev, and 95% are within 2.

    So, a score of 10 doesn't seem out of place at all. (And this is all high-school level stats, mind you, sticking to the Probability 101 theme here.)

    As someone with a masters in maths and PhD in physics, this is the same way I did the calculation. In fact, I suspect it's the way anyone who knows some more advanced maths would do it: What you've effectively done (in maths language) is:

    1) Use the associative property of multiplication and its inverse: (AB)C=A(BC).

    2) Rewrite the unknown product 47*3 in terms of two known products, by first rewriting 47=50-3, thus (50-3)*3.

    3) Expand the bracket: 47*3=50*3-3*3.

    Now this is much akin to the 'normal' method used to teach kids, except they always expand their brackets in terms of positive numbers broken up by powers of 10, ie 47=40+7, however from a mathematical standpoint there's no reason not to use any splitting you like, only the expedience of learning a limited number of multiplications.

    The true gift of good mathematicians is not only being able to make these thought processes, but properly explain them so that others can too. Far too often maths as it is taught is just a voodoo recipe for performing calculations rather than a well explained, reasoned setup. This is fine for people who merely have to perform the function (much as you don't need to know the workings of an internal combustion engine to drive a car) but if you want to derive a deeper understanding of what's going on its woefully insufficient.

    It depends on what the BS was in. A little more digging reveals this:

    A resident of Orange County for three decades, he has a bachelor of science degree in education and two masters degrees: in education and educational psychology.

    I'm not sure why the education undergrad degree was a BS, rather than a BA, but that, combined with the two master's degrees in education, explain a whole lot. He could probably have gone through all of those degrees, including the 15 hours towards a doctorate (by which he probably means an Ed.D., which is definitely not the same as a Ph.D.) without ever taking any math more advanced than basic algebra. Educational psychology might (and definitely should) have included basic statistics, but it might not have, and depending on the way the course was taught, might have been easy to skate through.

    Also, being able to oversee a large budget tell me nothing about his math ability. It tells me he has basic Excel skills. If he thinks he doesn't need those math skills in his job, he probably doesn't realize how much more efficiently/accurately he could be doing his job if he did have and use them.
