When did you take algebra? And should everyone do the same?

When I attended Karr Junior High School in New Orleans for my 7th and 8th grades, standardized testing had me on the college-prep track, along with a lot of my friends at the time.

But not one of us took algegra in the 8th grade. We weren’t allowed to. Everyone had to wait until the 9th. The thing is, I was no longer living there in the 9th.

That year, which my Dad spent in the mangrove swamps of IV Corps in Vietnam, I attended Bennettsville High School (an institution that, like the once-magnificent State newspaper building, has vanished from the Earth). We stayed there with my grandparents while my Dad was at war.

And in B’ville, the most academically inclined kids had taken algebra in the 8th grade, when I was taking plain “math” (and frankly, not doing too well at it). So I took algebra in the 9th with the cohort of kids who were also probably headed to college, but were not overeager to get there.

This will surprise some of you whose experience of South Carolina public schools has come after real integration came to the state in 1970. That’s when all the seg academies cropped up, and from then on white voters became gradually less and less invested (monetarily and in terms of giving a damn whether the public schools succeeded or not). I arrived at BHS three years before that happened, and things were in many ways the way they had been when my mother attended the older BHS downtown. All the middle (and upper) class white folks did what they could to support the Green Gremlins (easily the best and most original mascot name of all the schools I attended).

Also, economically, Bennettsville was a far more prosperous place than it is now. That helped.

Anyway, at that point South Carolina was ahead of Lousiana in math, in spite of all those free textbooks Huey Long passed out during the Depression. Still, only those kids assessed as having the skill were taking algebra in the 8th.

But suppose you see your entire community as the most academically advanced in the nation? What happens if you try to prove how wicked smaht all your kids are? (Although in Cambridge, they probably don’t say it that way, but leave that to the Southies.)

Apparently, this happens:

Cambridge made all eighth-graders take algebra. It went so poorly that 60 percent of students will have to retake it.

In other words, living near Harvard Yard, or even MIT, did not automatically endow children with outstanding math skills.

Perhaps they were skilled in other ways. You know how there are word people and number people? Maybe some of them repeating algebra will someday write the Great American Novel. Or become awesome auto mechanics (who can also be found in Cambridge). Different strokes. Also, even if kids have the same inclinations, their brains develop at different rates.

The Globe story contains a lot of fingerpointing, with some teachers charging (anonymously) that the administration rushed the rollout of this experiment, and and administrators saying no we didn’t.

The larger issue, of course, is whether all kids should be forced to learn at the same rate as those who are more gifted in what the Brits call “maths.” This seems doubtful to me, and in this passage the story backs me up:

Other districts and at least two states have tried offering Algebra I to all or most eighth-graders, and studies of those efforts have found negative results for less well-prepared students….

Secondary school is when you start individualizing education according to children’s personal talents and interests. It’s not the time to make them proceed at the same rates in every possible direction.

Anyway, thoughts? And what was your experience with math in school? Did that help or hurt? And do you recommend tailoring the curriculum to each individual student (as public schools have traditionally done, to the extent possible), or expected everyone to keep up on everything at the same rate (which trends more toward the small private school approach)?

SOME numbers are interesting, and significant

sigdig-1monday

We have a lot of arguments here based on the fact that some of y’all are numbers people and I’m a word guy.

But sometimes I appreciate numbers, too.

I don’t like them when they don’t mean much. For instance, back when I was still at the paper, there was a period in which the newsroom would post a “By the numbers” graphic with some stories. The numbers were usually not very pertinent to understanding the story. It was obvious that some senior editor (I suspect a managing editor who was at the paper in those days, but I don’t know because our interactions with the newsroom were minimal) had decreed that there would be at least one such feature a day, whether the story lent itself to that treatment or not.

But fivethirtyeight has a feature called “Significant Digits,” or “SigDig,” which identify stories with numbers that mean something. A sampling from today’s installment:

4 congressmen

Rep. Patrick Meehan, Republican of Pennsylvania, will likely face an investigation by the House Ethics Committee. Meehan reportedly used taxpayer money to settle a complaint by an aide that he made repeated romantic overtures towards her, and grew hostile when she did not reciprocate. Meehan was, until these accusations came out, on the House Ethics Committee that’s investigated the sexual misconduct cases of at least four male members. [The New York TimesThe Boston Globe]


86 patients

China is testing cutting-edge gene therapy technology on human beings, with at least 86 Chinese patients having had their genes edited so far. China’s regulations on experimenting with humans are considerably more lax than many other countries’. [The Wall Street Journal]


1,062 Twitter accounts

Twitter has discovered another 1,062 accounts linked to a Russian agency that tried to influence the 2016 U.S. presidential election, and will email 677,775 users who followed the accounts, or retweeted or liked one of their tweets. [Bloomberg]…

And so forth. That’s more like it! Every one of those numbers is a grabber, encouraging us to read further.

I mean, really: 86 Chinese people have had their genes “edited”? How many does it take before they can assemble a Chinese version of the X Men?

Odd interpretation of a poll result

This release left me scratching my head a bit:

Poll: Parents Say Too Much Focus on Standardized Tests

Opposition to Common Core Most Intense Among Parents

WASHINGTON, D.C. (June 26, 2014) — Parents of school-age children are unhappy with the amount of time spent on standardized tests and have strong opinions on other controversial education policies, including Common Core and school vouchers, according to a new national poll released today.

The Schooling in America Survey, released annually by the Friedman Foundation for Educational Choice and Braun Research, includes a statistically representative sample of school parents. It found 44 percent of those parents said children spend too much time preparing for and taking assessments; 22 percent said too low, 30 percent said the focus is about right, and 5 percent had no opinion.

So… 52 percent say kids spend about the right amount of time on standardized tests, or even not enough time, while 44 percent say they spend too much time on them.

What sort of group would look at those figures and come away with the headline, “Poll: Parents Say Too Much Focus on Standardized Tests,” which is only accurate in the sense that some parents (a minority) say that?

Oh. The Friedman Foundation for Educational Choice. OK. Yeah…

Mind you, I’m not sticking up for standardized tests here. I probably would have been in the 44 percent saying too much time is spent on them, although I’m far from passionate on the subject.

But what a screwy interpretation…
