    I liked the "convince your parents" section. I'm not really sure that being dependent on a calculator is such a good idea.

    I see things like "14/2", "sin(0)", Integral(1/x,x), etc. in people's histories all the time. Those are the things that you should know how to do; the calculator is making you lazy. Now for things like 239874/12398 calculators are nice, but I'm not sure it's worth $130 to a high school student for something that a 30 dollar scientific calculator can do fine. Graphs are nice, though.

    Going of on a tangent (heh), I rather dislike TI (I found a bug that kills your memory and TI refuses to fix it), so go with an HP48/49 if you need graphs. TI is for students that "want to do well on tests", HP is for people who do mathematics on a regular basis, IMO. That said, my TI89 is pretty useful.

        Well, from a purely pragmatic standpoint, it helps you work faster... the guy/girl who can do sin(0) in their head will inevitably finish a test faster, and hence have more time to check his/her work, than the guy/girl who has to punch it into a calculator, meaning better grades. And that ignores the benefits of actually *using your brain*...

        Frankly, I don't understand how you can defend the idea of needing to punch sin(0) into your calculator. I mean, honestly, if that isn't a symptom of the tool being used as a crutch, I don't know what is. How far does it need to go before you'll admit that the tool is being misused? Hey, maybe we should give calculators to the really young and screw teaching them how to add. After all, they've got *so much work* these days, why should they have to do it themselves when there's a tool to do it for them?

        because you need to understand the fundamental concepts behind them. Amount of work isn't the issue -- if you don't know what the sin of 0 is, you don't understand the sin function. Too much math is taught by saying "just punch it in the calculator", and then the student thinks sin is a magical function that throws out these numbers for no reason.
        Students in high school should never be allowed to use calculators at all -- let alone graphing calculators. They're a crutch that makes it even harder for them when they make it to college, or even the real world.
        Using a calculator to do problems in the real world is fine -- but calculators have no place in a learning environment.
        • I disagree. Students should be allowed to use calculators to check their work. It will save time for the teacher. If a kid wants to check to see if they've got sin(0) right, let them.

          But I never saw the point of flailing out derivatives and integrals when A)I knew I wasn't ever going to use them in my career as a web developer and B) If I ever had to do them by hand (meaning no calc) I'd have more important things to worry about, like finding food. (My calc is with me everywhere.)
          • I'd like to add that if someone had told me that I just had to learn calculus for a test that I wouldn't have resisted the idiocy that was my calc class so much.

            I'm going to do that for my kids, because unless you're a math geek, calc is just college credits, because you never see engineers solving derivatives on paper. That will let them focus on really important things, like band.

            The point is, if you don't know why the sin of 0 is 0, then it doesn't matter whether you got the answer right or not. I can understand not wanting to do derivatives and integrals -- but if you don't want to learn how to do them, why bother doing them at all? Calculus isn't required for IT degrees, at least not where I study, and if it is required, it's because someone who's probably a whole lot smarter thinks there's a good reason for it.
            I find calculus in many things outside a calculus classroom -- just because you don't use it in your job doesn't mean it's useless. Calculus is a way of thinking more than just a problem/solution kind of math -- learning how to do those derivatives and integrals teaches you how to think better than anything else I know of. And those engineers -- you may be right that they do them with computers and calculators all the time, but that doesn't mean they don't need to understand what the computer is doing to solve the problems. If you don't understand how to set up the problem correctly, the computer can't give you the right answer.

Without computer help, kids in the US can figure out some sequence of letters that makes them understood (I can't tell you how many times I've graded a Computer Science test with 'integer' spelled 'interger'). In China, missing a few strokes or adding one in the wrong place will completely change the meaning of the character. So, students there have trouble getting understood without having a computer help them pick out the correct characters.

      While I don't like it, I think of it as the slide-rule example. Who is required to learn to use a slide-rule anymore? It isn't required because it isn't needed. With the same argument, why should Chinese kids learn to write all the Chinese characters from memory when a computer picks out the correct words for them? Then, why should any student learn 7*8 when they have a fancy calculator (really a mini-computer) that will do the thinking for them? When these little computers do enough of our thinking about the unimportant stuff, we can spend more time thinking about important stuff, like the Simpons.
      • Or it can actually free you to think about more complex and important stuff. Try doning real world calculus problems by hand, it'll take you HOURS (at least). Now try and do more than one of them on a test, in less than an hour. You NEED a calculator to automate all the basic shit. Funny thing, you learn more about what's important too. It does not matter anymore to be Johhny-on-the-Spot with mental math. It matters to be able to apply high level complex math to real world problems in an efficient manner.

    I always preferred the 85/86 to the 83/82. The "UI" of the 85/86 is just... better. The buttons are organized the way they should be, and not grouped according to if you're doing your taxes or not.

    What about those ones? According to ticalc.org, they're the "engineering" oriented calculators, maybe that explains the above paragraph...

    Then there was also the 92/89 pair, but that always seemed a bit silly... I don't need to have 3d graphics, thank you :D

    The lack of support TI offers for users of the TI-86 calc is appalling. That friggin comparison chart _proves_ that for only $10US more than an 83+ Silver (dunno how much the new 84 costs) you get a _lot_ more features. This is the best TI calc you can buy for the money. The 89s and 92s are better of course, but they're about $70 more expensive last I checked. The 86 has more features in most areas and what it lacks can easily be made up for by a solid community of enthusiasts (www.ticalc.org) who write Z80

    In college I remember taking the final and 10 guys spent all of 10 minutes taking it. They had programmed their calculators with every possible question (from the homework) and all made 100%. I spent 3 1/2 hours taking the test because the test was so hard no one else was done in 3 hours so they gave us more time.

    I still hate those guys, but I am not bitter ...

    ...when you pry it out of my cold, dead hands.

    Prior to 1983, I went through at least one TI scientific calculator per year -- literally wore them out as an engineering undergrad. After having one go on the fritz during a chemistry final, it was time for a change.

    And what a change indeed. Bought an HP-41C, which was quite expensive on a student't budget, but I figured that maybe it would last two or three years. Twenty years later, it's still within arm's reach, looks just like the day I bought it, no bouncing keys, no flickering display.

    But the real reason it's still in my arsenal is that it turned out to be the ideal tool for working EE AC circuits problems. The '41 can do complex math, in both polar and rectangular coordinates, and flip back and forth between those two representations with ease. I have fond memories of walking out of a tough exam after only 20 minutes, handing my completed (and aced) test to the very suprised professor. Thanks Dave and Bill!

    I purchased the TI-83 Plus Silver Edition [ti.com] about a year and a half ago. The Processor is 2.5 times faster than the TI-83 Plus it has 24KB RAM and 1.5MB flash memory and it stores up to 94 applications. It also came with a cable to hook it up to an USB port. As far as I can tell, the 84 is nothing more than a repackaged 83 silver edition.
    On a good note - despite heavy use I have only had to change the batteries once in the last 1 1/2 years.

    You know, it's bizzare almost. This seems to be pretty much the only truly new calculator from TI in the 80x range since I was a sophomore in highschool, like 7 years ago.

    a 2.5x speedup? The machine I had then was a pentium 75! I guess this is what happens when you have no competition.

    Why would you need more CPU power in a graphing calc? Well, graphing for one thing. It can take a couple seconds for these things to draw a graph. There are plenty of high-power low-cost chips out there that could crank most of those out almost instantly.

    And lets not forget the games :P. TIs were fun in HS, but it's just amazing to me how little they've advanced...
