Final month, as I learn Christopher J. Phillips’ temporary and engrossing The New Math: A Political Historical past, I discovered myself reciting the ominous line from Battlestar Galactica:
Early in my instructing profession, I spent a whole lot of time and life-force railing in opposition to the shortcomings of a rote math training. The senseless manipulations. The paper-thin comprehension. The dearth of vital thought. I noticed it as my obligation to call (and blame, and disgrace) these patterns.
Because the years glided by, I noticed these critiques weren’t as recent as they felt. Individuals like me had been decrying strategies like these not only for years, however for hundreds of years. Such critiques didn’t actually disrupt the system; they have been a longstanding aspect therein.
Removed from difficult the established order, I used to be enjoying a snug function inside it.
These ideas got here speeding again as I learn Phillips’ pithy and potent historical past. There’s nothing new beneath the solar—at the very least, not in our philosophies of math pedagogy. The arguments simply go spherical and spherical.
Witness this passage, concerning the rival textbooks of Pike and Colburn:
Pike emphasised the significance of memorizing arithmetic guidelines after which making use of them to varied examples…
Colburn’s [approach] was to reverse rule and instance: as an alternative of presenting guidelines, he introduced easy examples in an effort to steer youngsters to kind guidelines for themselves….
Contemporaries understood the variations between the textbooks to be about variations in reasoning…
[One critic] proclaimed… that rule-based strategies failed as a result of a scholar wouldn’t have “been referred to as upon, on this course of, to train any discrimination, judgment, or reasoning…”
[Another critic] claimed that inductive strategies would… finally undermine authority by erasing the standard grounding of rigorous data in guidelines.
Is that this concerning the Widespread Core battles of the 2010s? Certain sounds prefer it.
However no, it’s concerning the New Math controversy of the Sixties. Proper?
Mistaken once more. Colburn revealed his e-book within the 1820s. Pike wrote his within the 1780s.
All of this has occurred earlier than. All of this can occur once more.
As Phillips elucidates, a silent assumption underlies either side of the Colburn/Pike debate. “Even—maybe particularly—on the most basic ranges,” he writes, “evaluating mathematical strategies entailed assumptions concerning the virtues of mental coaching.”
Let me spell that out: the shared assumption, the axiom that either side settle for, is that math training shapes the mind. Arithmetic isn’t just arithmetic. Nonetheless you handle issues of multiplication, that’s the way you’ll additionally strategy issues of democracy.
Within the Sixties, New Math reformers frightened that rote drill would breed blind deference to authority. They hoped as an alternative to create a society of mini-professors, seeing the world by way of versatile, summary buildings.
Within the Nineteen Seventies, “again to fundamentals” counter-reformers held the alternative hope, and the alternative concern. They believed rote drill inculcated self-discipline and diligence, and that the New Math would breed a feckless technology that was without end complicated true with false, proper with mistaken.
The rival camps favored reverse sorts of minds, and reverse sorts of math. However they shared a deep precept: Math makes minds.
I’ve lengthy operated on this similar precept. Important to a free and thriving mind—and thus, to a free and thriving society—is nice mathematical pondering, no matter that’s.
In the mean time, I can’t assist questioning if we’ve all acquired it mistaken. Possibly math training isn’t about broader mental habits. Possibly it’s not, as 17th-century Jesuits believed, a mannequin of how divine authority flows forth from unquestionable axioms. Possibly it’s not, in Underwood Dudley’s beautiful phrase, about “instructing the race to cause.” Possibly it’s none of these issues.
Possibly, if we wish to break the Battlestar Galactica cycle of countless “math wars,” we have to embrace a brand new axiom: math training is nearly math. Possibly these stakes are excessive sufficient.
