For those of you so inclined the NCES has a literal treasure trove of score breakdowns, graphs, interesting research, articles.

I go there often and everytime the PISA scores come out and everyone bleats about how stupid Americans are I like to wait for the NCES breakdowns. I linked to Math scores and depending on which group/state you live in, in America there are huge differences in score breakdowns. We do even better (well, some of us do better) when you look at Reading scores.

The research is out there, and now back to your regular finger-pointing circle jerk.

This is probably a better system:

"Trachtenberg System of Speed Mathematics

"When I was just seven or eight years old, I came upon a most fascinating book called the Trachtenberg System of Speed Mathematics (or something like that). In it was described a way of doing addition, subtraction, multiplication and division in ways I had never seen before. None of my teachers had even heard of it before. I was able to do multiplications by eleven and twelve in my head faster than my friends could do on paper. If you hate formal math (or if you have a child that does) . . "

"Jakow Trachtenberg was born on June 17, 1888, in Odessa, Russia. He worked as an engineer during his younger years in the Obuschoff Shipyards, after graduating with highest honors from the Mining Engineering Institute in St. Petersburg. He moved to Berlin during World War I and soon became an expert in Russian affairs. There he devised a method of teaching languages that is still used in some parts of eastern Europe. As a Jew, he was captured by the Nazis and deported to a concentration camp. There, without paper or pencil (some say a common iron nail became his most prized possession), he devised a method of doing mental arithmetic. Trachtenberg managed to escape and fled to Switzerland, where he perfected his system. In 1950, he founded the Mathematical Institute in Zurich where he taught his methods to children and adults alike."

I would also wonder if todays engineers can handle Grey Codes, Reverse 3 coding, or RPN calculations (RPN was often called Reverse Pollack Notation) . Oh the joys of those early HP-20 calculators!

There are still such things as right and wrong answers. Nothing can change that.
Do you remember a song by Tom Lehrer entitled "New Math"? As Tom noted, "It's so simple , so very simple that only a child can do it!" Dr. Tom Lehrer was actually a Mathematics instructor in the Mathematics Dept. at Harvard Univ. and that singing was just a hobby. Lehrer wrote this song over 50 years ago. A time when Americans worried that just teaching our kids reading writing and 'rithmetic wasn't good enough it we wanted to compete with the Soviet Union.

Remember the saying:
When you are openly gay, you are a Democrat.
When you are closet gay, you are a Republican.

Those who are most venomously against gays are usually gay themselves. Perhaps that applies to you.
Homophobics May Be Hidden Homosexuals | Homophobia & Anti-Gay Sentiment

What the right don't get is that real straight men (like myself) don't feel threatened by gays because they have no affect on us. Zero. But a closet gay who is in denial definitely would feel threatened!! And it shows in their behavior like saying things like, "Gay people destroy families!!" No, gay people won't destroy my family but it may destroy yours if the possibility of you leaving your family for a gay man exists.

Love it. "Who's Next" is a my favorite and just as timely as if he wrote it yesterday.

We could learn a lot from Tom Leher. he is on you tube. And you can still get his stuff from I Tunes.

I would tell Jack to subtract 300 then subtract 20 and then add 4 to the answer if he were doing the problem in his head. Doing the problem on paper is best doing it by simple subtraction as the engineer dad said.

It seems to be an attempt at learned universal stupidity.

I have met quite a few people who were learned stupid.

What aspects of common core teach stupidity?
