The first time I ever derived any enjoyment from a math class was calculus. Although the coursework was heavy and resembled Lockhart's descriptions, my teacher was excellent. She always tried to show us the why of things, not just the how, even though there wasn't much room for that in the class, and those parts were the ones that really stimulated my interest.
What's hubski's experience with math education?
Okay so I've been drinking more than a little bit and this post might be incoherent. But I feel like most subjects are already being taught fucking horribly in schools, not just math. I actually always loved math and had no problem with it. I just happened to be one of those kids who loved math so much that I managed to love it even with the boring-ass way it's taught in schools. But I had a horrible experience with other subjects in school, and particularly history. History is so goddamn boring the way it's taught. Why the fuck should I memorize seemingly meaningless names and dates? I always crammed the last minute right before tests so I wouldn't fail and then forgot everything, and I'm paying for it now by knowing fuckall about major historical events. Now that I've graduated high school and can learn history that I'm interested in on my own, history is fucking interesting as shit and I love it. But it was taught in such a terrible way in school (or at least, the schools I went to). In fact, I always hated science up until I had a fantastic science teacher in high school who made things interesting. Science is literally what I do for a living now. I can't even imagine where I would be if I had a bad high school science teacher. This is exactly how I felt the first time I did a proof in high school geometry. I was sitting there struggling, and then all of a sudden it came to me like a stroke of lightning. It fucking felt like I was creating something. Of course I wasn't, I was proving some boring old proof that tens of thousands of other kids had done before me, but it felt new and fun. I wanted more. Man, have we ever stopped to think about how mathematicians think about mathematics? This has actually been studied by cognitive scientists. One of the most important parts of thinking about a math problem is drawing shit on the board and talking aloud about it. Not doing endless exercises, not sitting alone in isolation like fucking Hollywood would make you believe. No, it's conceptually drawing stuff out and talking about it with another human being. Mathematical curiosity, list most other artistic and scientific curiosities, is a thirst for truth and beauty that you crave to share with other human beings. Okay this is probably the only thing I truly disagree with in this article. I don't believe anything is inherently interesting, and I'd bet that there are a lot of people who aren't particularly interested in this question for one reason or another. I think it must be recognized that not everyone can be interested in everything. I have a great deal of love for most things, including science, math, and many forms of art, but if I were asked in school to draw something I would not enjoy it. That's just a fact of my personality. Assuming that all kids would be inherently interested in mathematical questions is not a safe assumption. But I think it is a safe assumption that most kids would be more interested in math were it taught in a different way, which is the main point of this article anyway so I shouldn't nitpick too much. Ooh this is so true damn. Can I give this some snaps or is that reserved for poetry? But like seriously though, how do we solve this problem? Truly investing oneself in making sure that every student is thoroughly engaged with math is so hard and feels like it's beyond the call of duty for your standard teacher. It's funny how deep culture goes because I hadn't even thought about this before. As an aside though, I disagree with some of the author's dismissal of teachers and how teachers are trained but I'm not going to spend the next 5 hours quoting every single line and responding with paragraphs ;) Fuck man, this paper is so full of truths. One of the most annoying things about specialized fields is the specialized terminology that comes with them. I complain about this all the fucking time about my own field, linguistics. We use so many stupid ass terms that no one understands and no one becomes engaged with (except for linguistics, of course). We want people to become engaged with ideas, not memorize dumb terms, and this is what I was reminded of when I read that passage. Syntax and semantics are the worst with this, I swear... I loved proofs but seeing as I was the only one in the class who did this is probably a problem. See I always felt like I was having an epiphany, and then the only remaining thing was to write it out in the formal language we were taught in school. So fun!!! This guy is seriously predicting my thoughts right now! --- Thanks for sharing, this is something that spawns a lot of thought. (This post has been brought to you by four ciders)Now where did this idea of mine come from? How did I know to draw that line? How does
a painter know where to put his brush? Inspiration, experience, trial and error, dumb luck.
That’s the art of it, creating these beautiful little poems of thought, these sonnets of pure reason.
There is something so wonderfully transformational about this art form.
What matters is the beautiful idea of chopping it with the line, and
how that might inspire other beautiful ideas and lead to creative breakthroughs in other
problems— something a mere statement of fact can never give you.
Suppose I am given the sum and difference of two numbers. How
can I figure out what the numbers are themselves?
Here is a simple and elegant question, and it requires no effort to be made appealing.
It is far easier to be a passive conduit of some publisher’s “materials” and to follow the
shampoo-bottle instruction “lecture, test, repeat” than to think deeply and thoughtfully about the
meaning of one’s subject and how best to convey that meaning directly and honestly to one’s
students. We are encouraged to forego the difficult task of making decisions based on our
individual wisdom and conscience, and to “get with the program.” It is simply the path of least
resistance
It is not necessary that you
learn music from a professional composer, but would you want yourself or your child to be
taught by someone who doesn’t even play an instrument, and has never listened to a piece of
music in their lives? Would you accept as an art teacher someone who has never picked up a
pencil or stepped foot in a museum? Why is it that we accept math teachers who have never
produced an original piece of mathematics, know nothing of the history and philosophy of the
subject, nothing about recent developments, nothing in fact beyond what they are expected to
present to their unfortunate students? What kind of a teacher is that? How can someone teach
something that they themselves don’t do?
think the far greater risk is that of creating schools devoid of creative
expression of any kind, where the function of the students is to
memorize dates, formulas, and vocabulary lists, and then regurgitate
them on standardized tests—“Preparing tomorrow’s workforce today!”
you have to have something you want to run toward. Children can
write poems and stories as they learn to read and write. A piece of
writing by a six-year-old is a wonderful thing, and the spelling and
punctuation errors don’t make it less so. Even very young children can
invent songs, and they haven’t a clue what key it is in or what type of
meter they are using.
This is intimately connected to what I call the “ladder myth”— the idea that mathematics can
be arranged as a sequence of “subjects” each being in some way more advanced, or “higher”
than the previous. The effect is to make school mathematics into a race— some students are
“ahead” of others, and parents worry that their child is “falling behind.” And where exactly does
this race lead? What is waiting at the finish line? It’s a sad race to nowhere. In the end you’ve
been cheated out of a mathematical education, and you don’t even know it.
I: If we honestly believe that creative reasoning is too “high” for our
students, and that they can’t handle it, why do we allow them to write
history papers or essays about Shakespeare? The problem is not that
the students can’t handle it, it’s that none of the teachers can. They’ve
never proved anything themselves, so how could they possibly advise a
student? In any case, there would obviously be a range of student
interest and ability, as there is in any subject, but at least students
would like or dislike mathematics for what it really is, and not for this
perverse mockery of it.
In place of discovery and exploration, we have rules and regulations. We never hear a student
saying, “I wanted to see if it could make any sense to raise a number to a negative power, and I
found that you get a really neat pattern if you choose it to mean the reciprocal.” Instead we have
teachers and textbooks presenting the “negative exponent rule” as a fait d’accompli with no
mention of the aesthetics behind this choice, or even that it is a choice.
The curriculum is obsessed with
jargon and nomenclature, seemingly for no other purpose than to provide teachers with
something to test the students on. No mathematician in the world would bother making these
senseless distinctions: 2 1/2 is a “mixed number,” while 5/2 is an “improper fraction.” They’re
equal for crying out loud. They are the same exact numbers, and have the same exact properties.
Who uses such words outside of fourth grade?
The student-victim is first stunned and
paralyzed by an onslaught of pointless definitions, propositions, and notations, and is then slowly
and painstakingly weaned away from any natural curiosity or intuition about shapes and their
patterns by a systematic indoctrination into the stilted language and artificial format of so-called
“formal geometric proof.”
! A proof should be an epiphany from the Gods, not a coded message from the Pentagon
SIMPLICIO: Now hold on a minute. I don’t know about you, but I actually enjoyed
my high school geometry class. I liked the structure, and I enjoyed
working within the rigid proof format.
Just checking - for the two numbers problem, it's |s-d|/2 for the smallest number, and then s-x for the bigger one right? (assuming s is sum, d is difference, x is first number)
I've always had an interest in history, so when I went through high school history it was an easy class and I never had to work at it.History is so goddamn boring the way it's taught. Why the fuck should I memorize seemingly meaningless names and dates? I always crammed the last minute right before tests so I wouldn't fail and then forgot everything, and I'm paying for it now by knowing fuckall about major historical events. Now that I've graduated high school and can learn history that I'm interested in on my own, history is fucking interesting as shit and I love it. But it was taught in such a terrible way in school (or at least, the schools I went to).
Yeah see, that's how I always felt about math. I loved it so much that it was always easy for me and didn't have to work. I didn't have a natural affinity to history and ended up just hating it. But learning history on my own is so fun because I get to control what content I learn...I learn about the history of things that actually interest me, and I don't start by thinking, "hmm I should really memorize these names and dates because that's what history's all about".
The Mathematician's Apology, if I recall, is one of the essays mentioned regularly in the qualitative understanding of Mathematics. While rhetorically some parts of the essay are quite beautiful, the whole thing doesn't really enlighten the everyday reader on what Mathematics actually is. It attempts to make Mathematics analagous to art, but does not' make full use of the comparison to achieve any technical understandings. That said, this line from the essay is beautiful: "The proof is by reductio ad absurdum, and reductio ad absurdum,
which Euclid loved so much, is one of a mathematician’s
finest weapons5
. It is a far finer gambit than any chess gambit: a
chess player may offer the sacrifice of a pawn or even a piece, but
a mathematician offers the game.
" I have not read Lockhart's Lament to the end, but the thesis it seems to be hinting at is that schools kill appreciation of education all too easily. Which raises a hell of a lot more questions for society, let alone mathematics.
I love maths - and regularly use it during/for entertainment (such as doing some logic hardcoding for things in games like GMod's Wire and Rawbots, where they give you conditional, logical and arithmetic chips/gates to do whatever you want, even to the point of driving automation, or drawing up some data tables for stats for various experiments or roleplays, and so on). But it is only partially because of my education - unless you could autodidact knowledge as education. Because right up until I'd say third year of high school (Canandian school system - we have kindergarten at 4 or 5, six grades of elementary, then five years of high school - so, from what I can gather when comparing it to the American system, I think it's technically Freshman year) I was way ahead because my parents gave me learning material very early (late 90's/early millenium, and we already had at least one if not two decent computers, and until 2002 the best internet connection we could have - so I learnt my native language - reading and 'writing' (which really was typing) and vocabulary with educational software, English with Dr. Seuss, mathematics with what I THINK was the French equivalent to some version of Math Blasters... in kindergarten. I really just did have a headstart in learning) to the point where I was disinterested in class (along with other reasons - that's a long story). They almost got me to take Ritalin for me to pay attention (and that was ONLY for me to pay attention in class - and completely disregarding the fact that all of my work was done, and I wasn't allowed to do other exercises in the books early because I wouldn't have anything to do in the following classes - which was a moot point). Then the end of elementary rolled around, and they convinced my parents to pay the $10 to let me take the test to be inducted into some high-school advanced program (not even a good highschool, just one owned by the school commission - it even had some cheesy name like Dynamo instead of just being AP). That year everything got even more painful - I was still a good ways ahead, but my math teacher hated me and failed me (to the point of being put in assisted classes the next year, for those who really did struggles) simply because I did not use the methodology she wanted me to use (which I would later learn was STILL me being ahead, because two years later we had similar problems as a part of another problem involved in the curriculum - think it was using some low-class algebra within a statistics class or something, and THAT teacher told me the method was perfectly fine). In the meanwhile, at home, I was roleplaying on forums (using stats and dice) and playing more games that involved forms of mathematics (honestly? 90% of my math learning past the basics was done because of Garry's Mod Wiremod). Then I simply destroyed the curriculum the following four years (95% final grade in second year, above 80% every other year - physics and natural sciences were another beast though). So, the bottom line is - I find that the vast majority of the civilized world fails at teaching mathematics by being WAY too formal about it. If you want children to love mathematics like I do, make it a game - by giving them real possibilities of doing maths for something fun like contests, to playing actual games (Frog Fractions don't count) to, in being entirely relevant to today, programming. Math is really fun and really useful without mentioning that, when presented right and early enough, it's not particularly hard, and definitely not as hard as 90% of the people I know make it out to be. TL;DR: Maths are fun when learned in games. School fails at this. I love maths.
