An Advanced Math Education Revolution Is Underway In the U.S. (theatlantic.com)
AthanasiusKircher writes: The Atlantic has an >extended article on the recent surge in advanced math education at the primary and secondary levels in the U.S., arguing that last year's victory for the U.S. in the Math Olympiad was not a random anomaly. Participation in math camps, after-school or weekend math "academies," and math competitions has surged in recent years, with many programs having long wait lists. Inessa Rifkin, co-founder of one of these math academies, argues that the problems with math education begin in the 2nd and 3rd grades: ""The youngest ones, very naturally, their minds see math differently.... It is common that they can ask simple questions and then, in the next minute, a very complicated one. But if the teacher doesn't know enough mathematics, she will answer the simple question and shut down the other, more difficult one." These alternative math programs put a greater focus on problem-solving: "Unlike most math classes, where teachers struggle to impart knowledge to students—who must passively absorb it and then regurgitate it on a test—problem-solving classes demand that the pupils execute the cognitive bench press: investigating, conjecturing, predicting, analyzing, and finally verifying their own mathematical strategy. The point is not to accurately execute algorithms, although there is, of course, a right answer... Truly thinking the problem through—creatively applying what you know about math and puzzling out possible solutions—is more important."
The article concludes by noting that programs like No Child Left Behind have focused on minimal standards, rather than enrichment activities for advanced students. The result is a disparity in economic backgrounds for students in pricey math activities; many middle-class Americans investigate summer camps or sports programs for younger kids, but they don't realize how important a math program could be for a curious child. As Daniel Zaharopol, founder of a related non-profit initiative, noted in his searches to recruit low-income students: "Actually doing math should bring them joy."

I have noticed that Public education is getting better in the US. They are now teaching Math much more effectively (at least at the elementary school level). At first I thought the Common Core was dumb after my elementary school child showed me what he was doing, but after researching the teaching methods I know understand the reasoning behind techniques they are using. Plus the efforts of Code.org to introduce our kids to logic and programming at an elementary school level is really helping with all of their studies. Amazingly teaching basic logic helps in all aspects of life. Kudos to the Common Core people and Code.org. Too frequently the teaching "experts" are teaching the wrong techniques. Anyone who grew up learning "new math" (Venn diagrams, etc) in the early and mid 1980s public schools knows what I mean by that!
My father taught me binary in the early seventies when I was still in elementary school, with black marbles and a grey egg carton. I got it right away. Numbers were one thing, representations of numbers was another thing, and these could be whatever you found convenient, so long as you obeyed certain rules (I wasn't so accelerated that I immediately started banging out Euclid's Elements on the piano).
Then I thought really hard one Saturday afternoon about fractions (on the unit interval, which I thought of as positive integers with the numerator greater than the denominator), and discovered that even though there are a lot of them, it is possible to enumerate them exhaustively, though not by the traditional "counting up" procedure, which got me hooked into the problem of the common divisor thing.
The next project I recall was to exhaustive write out the Tic Tac Toe game tree. Since I was a lazy bastard (always have been) this involving thinking very hard about something somewhat like symmetry groups.
Over the annual summer visit to my grandparents—small town prairie Badlands without the cool geography, though often we managed a trip to see the hoodoos—I played a lot of solitaire on the golden-green shag carpet which Puss Puss—the duodecarian house cat who lived in the shadows under my grandparent's bed (the short duration of our visits was probably for her sake)—sometimes preferred in her dotage over asking out into the Canadian winter. Quite undeterred by the sticky and/or stinky patches, I managed to clearly formulate the concept of a "decision procedure" and that such a thing could be unambiguously specified; furthermore, I worked out (at first empirically) that the greedy algorithm was provably not optimal for Klondike (for me at that time, all Solitaire was just "Solitaire", though I knew several).
At age ten, the boundary between empiricism and proof is still a fuzzy one.
In grade five, I spent a lot of time (by myself) trying to puzzle out the rate-limiting step in long-hand square root. I had by then also discovered E=IR and P=IE. Pretty soon I had determined that this generates 4 choose 1 times 4 choose 2 simple algebraic forms. But for an entire painful week, some kind of thick cloud entered my brain and I couldn't reliably write all the forms down without a lot of mucking around; this I knew to be completely bogus, and a permanent blot on my record. By the time the cloud passed, I was pretty good at substitution and gathering. Later, when I first encountered a matrix (don't recall), I immediately went to myself "oh, that's just algebra, better organized". At least something stuck.
Now, during this entire period of my life, I was in a constant state of deeply repressed rage about this thing called "school", with all the inherent stimulation of Puss Puss waiting out the daily bedtime / ultimate final departure of the grandchildren (geriatric cat yay!) from the furthest dark remove under the master bed.
Grade six came as a shock. For the first time I experienced a math teacher who believed in letting kids learn at their own natural rate. He quickly put four of us a private work program. We could go as fast as we wanted, but the rule was we had to do all of the tedious exercises at the end of every chapter. Many of these exercises were heavy on the pencil work, so I only made it through grades six, seven, eight, and nine. My fingers put in about 90% of the work (this is not actually a bad thing), and my brain put in the other 10% (this being 100 times more than 0.1%). Awesome!
So I was armed, locked, and loaded for bear when I showed up at the beginning of grade seven. I figured I could knock off ten, eleven, twelve by Easter, and still have a month left over for real math at long last.
Problem: my grade seven teacher thought my purpose in life was to sit enthralled by his boring lectures. Shields up! I don't recall a single thing he wrote on the board
