  •  No one is talking about higher mathematics. (6+ / 0-)

    Algebra and the fundamentals of calculus are mastered by high-school students in many countries.  Yes, it requires effort, but it makes it much easier to understand the world quantitatively, and it affords a certain immunity against bullshit.  

    No one who understands the exponential function would go for a balloon mortgage, or believe that our society is sustainable, however peaceful your neighboorhood might look.  In fact, a lot of RepubliCrap propaganda is easily disposed of if one understands basic algebra and calculus.

      The understanding you speak of requires a level of sophistication that our schools don't provide and that I think can't be provided anyway. Few people in America or abroad are willing to invest the effort in making the analysis you suggest even of they are capable of it (which I doubt).

        ... I honestly don't think most people have the ability.  Not just the knowledge, but the actual ability.  I'm not running down the "average" mentality, but all too often those who are above average seem to forget that they are above average.

        And, sorry, as someone who flunked out of Algebra I twice in high school and therefore ended up dropping out of school completely, I consider algebra to be higher mathematics.  Arithmetic is essential for getting by in the world, just like basic literacy is, but one does not need to clear a bar like Algebra anymore than they need to be able to critically read Chaucer in order to be a good functioning contributor to our society.  

        But denying them a high school diploma for that lack sure does make it less likely they'll be able to contribute in any positive way.

          diploma for not being able or willing to learn math, but there is nothing wrong with encouraging students, setting expectations and teaching it right.

          And the Algebra=Chaucer equation is way off base.  Chaucer is but one author, and he wrote in what is for all intents and purposes a different language that is no longer useful in our world.  One leans Middle English and reads Chaucer to broaden one's horizons.

          But algebra is everyone.

            I think a concrete, applied algebra is appropriate to describe as being for everyone. Few people ever have the need to have a genuine understanding of something even as basic as the empty set (for example) much less the concept of number base, various polynomial theorems, graphing things other than very basic linear equations, and so forth.

            The concept of limit, basic dericatives, and even useful application of say Newton's Method (e.g. for approxinting square roots), and so forth is even further removed from necessity. May as well tell them they should read up on Tangent Bundles and Killing Fields or the fun of S(2) groups while we are at it: it's about as useful and comprehendable.

          •  But, that's not what happens in American schools. (0+ / 0-)

            In our schools you aren't encouraged to learn Algebra, you are forced into it and if you can't do it you pretty much get to live your life at the earning potential of a GRADE SCHOOL dropout.

            Algebra as an option, Arithmetic as a requirement.  Not everyone is going to grow up and be an engineer, they really aren't.  We NEED good plumbers, carpenters, we need good Grocery Store managers.  It's OK.  It's honest work.

            I also know a English Literature Prof who would agree that the comparison is way off base, but for the opposite of your reason.

            Since I don't really have a dog in that race, I don't understand Algebra or Chaucer, I'll settle for "Both Are Superfluous To Most People's Lives".

              prof's reasoning.  I'm not hard to persuade with lucid argumentation.

              Is your friend a Kossack?  Invite him to explain why he/she thinks learning Middle English is important for everyone and learning algebra is not.

      that expects EVERY student to master calculus in high school.

      Their elites, sure.

      And it may shock you to know that I know some very conservative Republicans who are quite good at math and physics. (Plenty of liberals who do too.)

      Fry, don't be a hero! It's not covered by our health plan!
