I was a big math nerd in school and the multiplication methodologies in the op seem reasonable to me. Different doesn't mean worse. And calculators shouldn't be allowed in middle school. Or high school.

The IRS provides a $250/year tax credit to teachers who buy their own supplies. Thanks for the comment. Yes basic school supplies are quite affordable which I have no problem giving them out. I don't think teachers need to make as much as a GP or an engineer. Of course I'd love a modest pay increase like anyone else. I make enough to provide food, clothes, shelter, and medical care for my family so I'm fairly satisfied on that front. What I object to is your idea that being a good teacher is an easy job. If I just stood I front of the room reading a PowerPoint the room would be a circus within 5 minutes. Yeah talking about basic math is easy, getting a bunch of ADD phone addict punks to pay attention and actually learn some skills is really challenging. Not in the same way as being a longshoreman or oil rig guy of course ffs

I was a math major for a while and despite that the 'proofs' part of math never really entered into classes until the final 2 years. It would have been great in the long run if during the first 2 years of college Calc, CS, Trig, Lin. Alg. we did more than gloss over the formula and then have us memorize it in order to solve things. You're so used to dealing with math as 'numbers' or word problems that you have to figure out how to use the math you know to solve. When all my Math suddenly shifted to pages of letters and words and explaining why A(x) = B(z)+Z(y), I did not do well because it was something that I couldn't grasp what they were looking for, what they were wanting, etc.

I was fine until it got up to multiplying matrices and such. It felt like pulling teeth. Luckily com sci math stopped at that point or I'd have flunked from migraines. Or just plain flunked. My brain isn't big enough to see it as anything other then disconnected and abstract. I found that demoralising. GRINDCORE MEGGIDO fucked around with this message at 18:06 on May 16, 2018 |

I've got a few teacher friends and they teach using the box method. It's a nice visual way to break numbers down into their places and it's good for students who struggle with the traditional stacked method. They also use it when multiplying polynomials instead of FOIL, since it's better for polynomials with more than two terms. And teaching anbody anything is lovely and difficult if they're unwilling or unable to learn. You've got to be able to convey the same information in multiple ways so it makes sense to different people, you need to be able to answer any questions they have, you need to keep them interested, and you have to do it fast because there's 29 other people who are also failing to grasp the lesson. That's on top of parents who are pissed their kid isn't doing better, school officials who are pissed that you're behind schedule and your scores aren't up to standards, kids who can't or don't want to learn, and your own desire to teach these children properly.

Did they not require linear algebra? We had to take it for my program and it’s a must know for many CS fields, anything from machine learning, to graphics, to even something like search engines. Linear algebra takes some time to get used to, but it is really cool when you get the hang of it!

I like linear algebra and apparently actually figured out large parts of it myself working out various geometry problems and stuff. So I figured I might as well take a course in it at Uni since I already knew it. So I did. Took all the practice tests from previous years and they were easy-peasy. No probs. Then I go to take the actual test for that year. Hoo boy. "Invert this 5x5 matrix, write down all the steps " "Calculate the eigenvectors and values of these enormous matrices and shove them up your rear end " "Factorize this high grade equation " "No you can't use a calculator " "You have three hours + 20 more questions " Like, the biggest matrix they worked on in the tests for the previous years was 4x4. It's not that it's conceptually harder to work on larger matrices but the sheer number of arithmetic operations involved makes it extremely hard not to gently caress up a number somewhere when you do it by hand. It's like, what the gently caress is this, a course in number crunching? They were multiple point questions, so you'd think if you showed that you knew how to invert a matrix you'd get a few points, but fucken NOPE. lol @ you for wasting your time on those questions. Biggest loving piece of bullshit I ever seen. I still passed, but just barely, and now my grades make it look like I mysteriously suck at just linear algebra.

I managed to get through almost all my undergrad without a graphing calculator and just the basic scientific ones. Then my orbital mechanics class my senior year started requiring multiplication of 3 3x3 rotation matrices for coordinate transformations. It wasn't hard math but just so time consuming to do on tests. And then my composites classes required 6x6 matrices for stress-strain conversions. Not hard math but a pain in the rear end to do on a test when the professor writes the exam thinking everyone is going to be using a graphing calculator that you can just plug 9 numbers into some open & closed brackets and push enter. The box method is cool to do in your head and I think alot of people just intuitively do it as a way of rounding to make numbers easier to work with. The lattice method is neat but I would hate to be forced to do it in order to receive credit for a correct answer. It seems like the biggest problem with common core principles isn't that the method is wrong or bad, just different, but that you HAVE to do it that way or you don't get credit.

It's not clear to me what skill they think anyone will learn by having them multiply huge matrices by hand. If they were symbolic, like how to derive a projection matrix for homogenous coordinates or something, sure, but they never suggested stuff like that was even possible.

your friend a dog posted:that's true, but don't they use the same lesson plan every year? seems like a lot of that stuff is work that gets sorted out in the first year or two. On the high school level teachers will be switched around and given new sorts of classes fairly frequently and can never be assured it won't happened, on the elementary level that might be true but the level of responsibility and management with the kids is through the goddamn ceiling. You have a bachelors katana guy? I invite you to go get a job as a substitute and work some elementary days, where you don't have to do even a fraction of the prep and planning and organization. But will still feel like you got hit by a freight train at the end of the day.

ok fair enough but my point is that it's unrealistic to suggest that math doesn't have real-world applications, and mental math is good practice for solving logic puzzles and developing critical thinking skills. implementing and troubleshooting netplay without understanding how to crunch even basic math in your head? not bloody likely

My high school had one calc teacher and she was crazy and really old and hated kids and if you expected to learn calculus, well, good luck because you were essentially on your own with a textbook. She was the kind of teacher that expected us to read the chapter, answer every problem at the end of the chapter, and she'd drone out the teachers edition answers the next day, and that was the limit of her responsibility. I mean seriously she's the calculus teacher and she hasn't even done the math to realize she would make more money being retired, and she wouldn't have to put up with the kids she took every opportunity to complain about, and she wouldn't have to go to work, but she kept at it and wouldn't let anyone else teach Calc because she'd been there the longest so she had seniority. Plenty of kids can hack it, but I expect only the ones with a natural propensity for math, so the administration didn't seem to think it was an issue when I brought it up as I dropped the class. I ended up taking trig at a community college instead and the teacher was really laid back and stressed the fundamentals and didn't really care about homework so long as you made a token effort. He would write tests that would seem really intimidating at first but were essentially holding your hand through the current lesson's themes and operations, he just had that knack some do that makes math more like a story: with a natural exposition>rising action>climax>falling action>resolution to his problems. Not like super flowery word problems, but in how you attacked the actual math. If there was a complicated formula you needed to use, he'd incorporate it in a different problem somewhere in the test so you could refer back to it, he's not leaving land mines that punish you for not having a computer like precision for random formula only a handful of specialists in limited fields even use regularly, but he still makes sure you'll know how to apply it properly. It felt like magic, like he was some kind of math wizard who was more interested in students doing and understanding math, rather than just babysitting kids while their parents are at work and hopes and prayering your way into an educated work force.
