“Provides a fresh way of thinking about math, and education in general, that should inspire practical applications in the classroom and at home.”

“It is, quite frankly, one of the best critiques of current K12 mathematics education I have ever seen, written by a firstclass research mathematician who elected to devote his teaching career to K12 education.”
Keith Devlin, The Math Guy on NPR’s Weekend Edition

“This brief and elegant celebration of mathematics is a charming rant against the way you and I learned the subject. Is painting just coloring in numbered regions? Is the sunset just a list of wavelengths and a compass setting? No more, Lockhart argues, than mathematics is just definitions and formulas. To put back play and joy in our mathematics classrooms, he shows, all we need do is restore the real mathematics.”
Robert P. Crease, author of The Great Equations: Breakthroughs in Science from Pythagoras to Heisenberg

“A Mathematician’s Lament is a fascinating argument that anyone interested in mathematics education should read. I promise that they will enjoy the experience, whether they agree with all that Lockhart writes or not.”
Bryan Bunch, author of The Kingdom of Infinite Number: A Field Guide

“Lockhart has written an important, and eloquent, lamentation and exultation: he laments about the state of math education today, but exults in the hope that teachers might be inspired to invite students to experience mathematics as the exciting ‘poetry of ideas’ that it truly is.”
Barry Mazur, Gerhard Gade University Professor, Harvard University and author of Imagining Numbers (particularly the square root of minus fifteen)

on
A brilliant research mathematician who has devoted his career to teaching kids reveals math to be creative and beautiful and rejects standard anxietyproducing teaching methods. Witty and accessible, Paul Lockhart’s controversial approach will provoke spirited debate among educators and parents alike and it will alter the way we think about math forever.
Excerpt from A Mathematician’s Lament
A musician wakes from a terrible nightmare. In his dream he finds himself in a society where music education has been made mandatory. “We are helping our students become more competitive in an increasingly soundfilled world.” Educators, school systems, and the state are put in charge of this vital project. Studies are commissioned, committees are formed, and decisions are made—all without the advice or participation of a single working musician or composer.
Since musicians are known to set down their ideas in the form of sheet music, these curious black dots and lines must constitute the “language of music.” It is imperative that students become fluent in this language if they are to attain any degree of musical competence; indeed, it would be ludicrous to expect a child to sing a song or play an instrument without having a thorough grounding in music notation and theory. Playing and listening to music, let alone composing an original piece, are considered very advanced topics and are generally put off until college, and more often graduate school.
As for the primary and secondary schools, their mission is to train students to use this language—to jiggle symbols around according to a fixed set of rules: “Music class is where we take out our staff paper, our teacher puts some notes on the board, and we copy them or transpose them into a different key. We have to make sure to get the clefs and key signatures right, and our teacher is very picky about making sure we fill in our quarternotes completely. One time we had a chromatic scale problem and I did it right, but the teacher gave me no credit because I had the stems pointing the wrong way.”
In their wisdom, educators soon realize that even very young children can be given this kind of musical instruction. In fact it is considered quite shameful if one’s thirdgrader hasn’t completely memorized his circle of fifths. “I’ll have to get my son a music tutor. He simply won’t apply himself to his music homework. He says it’s boring. He just sits there staring out the window, humming tunes to himself and making up silly songs.”
In the higher grades the pressure is really on. After all, the students must be prepared for the standardized tests and college admissions exams. Students must take courses in scales and modes, meter, harmony, and counterpoint. “It’s a lot for them to learn, but later in college when they finally get to hear all this stuff, they’ll really appreciate all the work they did in high school.” Of course, not many students actually go on to concentrate in music, so only a few will ever get to hear the sounds that the black dots represent. Nevertheless, it is important that every member of society be able to recognize a modulation or a fugal passage, regardless of the fact that they will never hear one. “To tell you the truth, most students just aren’t very good at music. They are bored in class, their skills are terrible, and their homework is barely legible. Most of them couldn’t care less about how important music is in today’s world; they just want to take the minimum number of music courses and be done with it. I guess there are just music people and nonmusic people. I had this one kid, though, man was she sensational! Her sheets were impeccable—every note in the right place, perfect calligraphy, sharps, flats, just beautiful. She’s going to make one hell of a musician someday.”
Waking up in a cold sweat, the musician realizes, gratefully, that it was all just a crazy dream. “Of course,” he reassures himself, “no society would ever reduce such a beautiful and meaningful art form to something so mindless and trivial; no culture could be so cruel to its children as to deprive them of such a natural, satisfying means of human expression. How absurd!”
…
Sadly, our present system of mathematics education is precisely this kind of nightmare. In fact, if I had to design a mechanism for the express purpose of destroying a child’s natural curiosity and love of patternmaking, I couldn’t possibly do as good a job as is currently being done—I simply wouldn’t have the imagination to come up with the kind of senseless, soulcrushing ideas that constitute contemporary mathematics education.
Everyone knows that something is wrong. The politicians say, “We need higher standards.” The schools say, “We need more money and equipment.” Educators say one thing, and teachers say another. They are all wrong. The only people who understand what is going on are the ones most often blamed and least often heard: the students. They say, “Math class is stupid and boring,” and they are right.
