    Southern Australia is low-light, now? I live in South Australia (~38 South), and I would have to disagree. In the summer, there is enough radiated heat to make facing towards the sun in the afternoon rather unpleasant, and skin cancer is very common here. In the winter, there is enough light to keep the air warm, and it very rarely reaches zero (by very rarely, I mean that when it does happen, it happens once a year. Usually for a short enough period that there are no effects beyond a thin layer of frost on anything).

    That question is about the same level of difficulty as an Australian test question (the exam questions tend to be a bit easier (examples below)), and we have only ~20 million people. Examples (PDF): While I am not sure about the number of places available in the Australian university system, the British question shown will only tell you who paid attention in Year 9 and Year 10. I hope to God that that isn't the level of Year 12 maths over there.

  5. Re:Interestingly Enough, No Examples Provided on Encouraging Students to Drop Mathematics · · Score: 1

    Something similar happens in South Australia - easier classes tend to be scaled down a couple of marks (eg. a 17 in English Communications tends to be knocked down to a 15/16 or so). If you have a final mark of 19 or 20 (out of 20) in one of the easier subjects, you get to keep that mark. Someone doing a disgustingly easy subject to get higher marks isn't as much of a problem, since if you don't do Specialist Maths/Physics/whatever three or four subjects (out of five) are listed as a prerequisite for your course, you don't get in (actually, it may be that you can get in if you pay the fees yourself, but most people take the government-funded route).

    Why are the British universities accepting applicants that need to be retested on work that should have been done in Year 9/10?

    Well, to be fair, Australians tend to be far more civilised about these things. Down here you can sit in the airport without having to endure people shouting into a phone (judging by the number of people from the US that I hear complaining about it, it sounds as though people are incapable of talking normally into a phone there). I suspect that voice calls are blocked so as to keep bandwidth requirements down.

  11. Re:graphing calculators on More Videogames, Fewer Books at Some Schools? · · Score: 1

    In an educational scenario, you should be recording your chain of calculations on paper. No exceptions. If you aren't recording the calculations, how's anybody (including yourself, during revision) going to see how you came to the answer?


    The recorded steps are what you mean to do. The steps in the calculator are what you are actually doing. Changing that constant that you mistyped in step two of part one of the question, and then correcting the subsequent results is far easier when you don't have to manually recalculate parts one, two, three, and four. If you get your steps right, you get four marks out of five, but being able to get the last mark without retyping everything may save save a few minutes, which can sometimes add up to a significant number of marks in an exam or test. It also stops you from adding even more typos, which is always a good thing.
  12. Re:graphing calculators on More Videogames, Fewer Books at Some Schools? · · Score: 1

    The ability to go back and see (and modify without completely redoing) ones chain of calculations is rather useful in physics and chemistry. I'm not sure why you'd want one in middle school (is that years 8-10 in the US?), but towards the end it would probably be useful to have.

    While a graphical calculator is not necessarily useful for calculus (with the exception of checking tangents), there are still quite a few places where they are (at least in the South Australian curriculum, I cannot speak for the American educational system). They're certainly not a "never-used brick of never-touched buttons".

    Slightly off-topic, is there anywhere that one can see the exams that I always hear Americans complain about the simplicity of? Are they the SAT tests?

  15. Re:AP students on Paying for Better Math and Science Teachers · · Score: 1

    I see. Over here the subjects aren't separated as much, so one couldn't do that. The only options for maths, for instance, are Maths Applications ("How much dirt will you have to move after you've dug that ditch?"-type stuff. That's not an exaggeration, the curriculum in Year 11 really does involve that type of problem), Maths Studies (Basic differential and integral calculus, matrices, etc.) and Specialist Maths (trigonometric functions and calculus, advanced complex numbers, differential equations). You can't just do one topic (eg. calculus) separately.

    That said, you aren't allowed to take the upper-level courses (eg. maths studies/specialist, English studies, chemistry, physics, etc.) unless you show some level of competence, which helps avoid having a third of the class holding everyone months behind.

    BTW, I don't believe the government should dictate what kind of light bulb you can buy, because the market can do that more efficiently and without as many negative side effects.

    If that were the case, we wouldn't be using incandescent globes. The legislative changes are going into effect because the market has failed to make the switch to something more efficient.

    Australia's power is mostly from coal, which we have in large amounts. Reduction in electricity usage is always a good thing, at least until we get nuclear going (which is a whole other issue; there's only one party willing to support that, giving you the choice between carbon dioxide and Liberal industrial-relations and foreign policy).
