A mathematician’s nightmare: Lockhart’s lament

I might have posted this already, but here it is again for George! One of my favourite texts written by a mathematician about mathematics and the way in which it is (but ought not be) taught.

My pet hate: I wish people stopped opposing “math” to “creativity”!

What a bad article to read before going to bed at 1am. Now I won’t sleep, grr. No, the article itself isn’t bad, it is even making a valid point: “Creativity just as important as math and science”. What made me angry, you ask? 

The argument is always “science and math are essential, especially in today’s job market”. I agree, they are essential on the job market. Just as literacy, the ability to retell, interpret, improvise, communicate, the knowledge of history, cultures and languages. Many things are important “on today’s job market”. But I do wish people asked themselves more often what is essential for the development of a person, for the wellbeing of society, and for the enjoyment of life. Perhaps then – to come back to our “not enough people do math” problem which is only a symptom of  a bigger problem in the way we treat learning – more people would enjoy playing with maths. But Peter Lockhart said it better. I am going to shamelessly quote the first 1.5 pages from his amazing essay just to make sure that more people read it. Please, read it, whether you have always liked, hated, or been undecided about mathematics. I will check in my stats how many people click on the link.

Amusician 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 sound-filled 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 wetake out our staff paper, our teacher puts some notes on the board, and we copy them ortranspose 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 quarter-notes 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 third-grader 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 non-music 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!”

Meanwhile, on the other side of town, a painter has just awakened from a similar nightmare…

I was surprised to find myself in a regular school classroom— no easels, no tubes of paint.”Oh we don’t actually apply paint until high school,” I was told by the students. “In seventh grade we mostly study colors and applicators.” They showed me a worksheet. On one side were swatches of color with blank spaces next to them. They were told to write in the names. “I like painting,” one of them remarked, “they tell me what to do and I do it. It’s easy!”

After class I spoke with the teacher. “So your students don’t actually do any painting?” I asked. “Well, next year they take Pre-Paint-by-Numbers. That prepares them for the main Paint-by-Numbers sequence in high school. So they’ll get to use what they’ve learned here and apply it to real-life painting situations— dipping the brush into paint, wiping it off, stuff like that.
Of course we track our students by ability. The really excellent painters— the ones who know their colors and brushes backwards and forwards— they get to the actual painting a little sooner; and some of them even take the Advanced Placement classes for college credit. But mostly we’re just trying to give these kids a good foundation in what painting is all about, so when they get out there in the real world and paint their kitchen they don’t make a total mess of it.”

“Um, these high school classes you mentioned…”

“You mean Paint-by-Numbers? We’re seeing much higher enrollments lately. I think it’s mostly coming from parents wanting to make sure their kid gets into a good college. Nothing looks better than Advanced Paint-by-Numbers on a high school transcript.”

“Why do colleges care if you can fill in numbered regions with the corresponding color?”

“Oh, well, you know, it shows clear-headed logical thinking. And of course if a student is planning to major in one of the visual sciences, like fashion or interior decorating, then it’s really a good idea to get your painting requirements out of the way in high school.”

“I see. And when do students get to paint freely, on a blank canvas?”

“You sound like one of my professors! They were always going on about expressing yourself and your feelings and things like that—really way-out-there abstract stuff. I’ve got a degree in Painting myself, but I’ve never really worked much with blank canvasses. I just use the Paint-by-Numbers kits supplied by the school board.”

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 pattern-making, 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, soul-crushing ideas that constitute contemporary mathematics education.

Apparently someone came to this blog by searching for “active learning in maths good or bad”… I wish I could tell them, without active learning there CAN BE no maths. Maths is all about DOING it yourself. But what do I know, I’m just a sociologist who thinks maths is fun.

Passive learning in maths!?

Maths, active learning and metacognition

An interesting article about a new book which explains how we learn to learn, and how to teach students how to think: “Critical Maths for Innovative Societies: The Role of Metacognitive Pedagogies”.

“College professors often point out that their students never learnt how to learn. Derek Cabrera was surprised to find that even the “cream of the crop of our education system” was not good at dealing with novel problems in unstructured assignments. As PISA shows, across OECD countries, about one in five students is able to solve only straightforward problems – if any – provided that they refer to familiar situations. Too often, we teach students what to think but not how to think.

Yet, there is an engine we can use for that and it is called metacognition, which means “thinking about your thinking”, and regulating it. Metacognitive pedagogies improve academic achievement: content knowledge and understanding, and the ability to handle routine and unfamiliar problems. And they also boost affective outcomes, reducing anxiety and improving motivation. Struggling students greatly benefit from these pedagogies, but not at the expense of higher achievers.

Metacognition is about taking ownership of your learning and maximising it. “It turns you from being a consumer of learning to being a researcher, a co-producer, an explorer and that’s a much more exciting, exhilarating world. You discover how to learn better” Stephen Heppell argues. He also points out that metacognition makes students “do 20% better – you get an extra Friday every week”.”
