The Math and Science Scam

The New York Times has a debate on the value of foreign technology workers that's worth reading.

Norman Matloff in Suppressing Wages With Younger Workers, provides an insight as to why studies of American education always imply that Americans are illiterate in these areas.
A core problem with the H-1B program is its impact on older U.S. workers. The median age of H-1B workers is 27, and since younger workers are cheaper, employers use H-1B to avoid hiring older (i.e. over age 35) U.S. citizens and permanent residents. Human resources departments routinely exclude the applications of older workers on the grounds that the applicants have experience beyond the range stated in the job ad. Proposals to grant green cards in lieu of H-1B visas are thus misguided, as they would still swell the young labor pool.

The hiring managers have a “gotcha” for the younger applicants too, rejecting them as lacking job experience in some special (but quickly learnable) skill.

The industry lobbyists note that 50 percent of Silicon Valley startups have been founded by immigrants. But since immigrants make up half of Silicon Valley engineers, the lobbyists’ figure merely shows that entrepreneurship rates of immigrants and natives are the same. There is no evidence that the displacement of American workers has produced a net increase in startups.

The world’s “best and brightest” should be welcomed, but most H-1B workers are not in that league. Meanwhile, many of our own best and brightest are squeezed out of the market once they become “expensive.” The industry’s
claim that American kids don’t study enough math and science is a red herring, and is rank hypocrisy, with the layoffs of thousands of U.S. citizens and permanent residents who were math and science whizzes as kids.


What Norman fails to observe is that high tech jobs were one of the job sectors in which [American] women reached and exceeded income parity with their male counter-parts.

This blog has long asserted that the math and science studies were largely manufactured to justify increased legalized job pirating practices.

Math and science teachers deserve an apology for being falsely accused of incompetence. On the other hand their complicit silence is unfortunate and sad.

Physics, Math, Science Videos

I owe reddit a hat tip on this one; JEE TV. This site bubbled up with wonderful videos done by teachers for science classes. Each video is a tutorial or demonstration of a math or scientific principle.

Very nice stuff.

Here's the linky.

Suggesting Expectations

A few months ago, this study covered briefly by the Washington Post is interesting.
Telling women they cannot do well in math may turn out to be a self-fulfilling statement.

In tests in Canada, women who were told that men and women do math equally well did much better than those who were told there is a genetic difference in math ability.

And women who heard there were differences caused by environment -- such as math teachers giving more attention to boys -- outperformed those who were simply reminded they were female.

The women who did better in the tests got nearly twice as many right answers as those in the other groups, said Steven J. Heine, a psychology professor at the University of British Columbia in Vancouver.

"The findings suggest that people tend to accept genetic explanations as if they're more powerful or irrevocable, which can lead to self-fulfilling prophecies," Heine said.
I can't help but wonder if before giving these high stress achievement tests if we should put together a carefully worded pep talk about how well our students always do by being conscientious and so on.

It might raise the scores simply by suggesting the scores will be higher.

I Think Bill Gates is Trying to Kill Me

About a week ago, I read Bill Gates Pushes for Better Schools by Nancy Zuckerbrod over at the Huffington Post.

Bill Gates has become a bit of a perennial, one-man, dog and pony show in Washington. Politicians kiss his ass in the hopes of landing Microsoft campaign dollars and he is given the attention usually reserved for people who have something interesting to say. The mind-numbing redundancy of his perennial self-serving platitude makes my eyes water. Only listening to Joe Lieberman drone on makes my eyes water more.
"As a nation, we should start with this goal: Every child in the United States graduating from high school," he said.
That's commendable at face value but this country has a severe illegal immigration problem. One would think that Gates would couple this platitude with, "and, by the way, another goal is that every able-bodied citizen have a job and pays taxes before I ask you to lift the limit on H-1B visa workers."

No such luck.

"We simply cannot sustain an economy based on innovation unless our citizens are educated in math, science and engineering," Gates said.

Legislation moving through the Senate, backed by Democratic and Republican leaders, seeks to get more people to become math and science teachers and would improve training for them. The bill also seeks to get more highly trained teachers in poor schools and would offer grants to states to better align their teaching with what kids should know to succeed at a job or in college.

Gates said the nation's economy depends on keeping the country's borders open to highly skilled workers, especially those with a science or engineering background. Federal law provides 65,000 H1-B visas for scientists, engineers, computer programmers and other professionals every budget year. High-tech and other employers say that's not enough.

"Even though it may not be realistic, I don't think there should be any limit," Gates said, adding that Microsoft hasn't been able to fill approximately 3,000 technical jobs in the United States because of a shortage of skilled workers.

What Gates fails to mention is that he dropped out of Harvard with very little math, science and engineering to get where he is today. And he is no futurist because he fails to mention that many things learned in high school and college are obsolete every three years. But he's not there to reform education but to whine.

His real issue is the latter, cheap and unlimited floods of technical labor. You see I've been unemployed for about six weeks already and I've got 25+ years of technical expertise. And I'm not alone. High-tech professionals are unemployed more often and for longer periods than unskilled labor these days according to unemployment studies. But Bill Gates can't find us because he would like us to go away somewhere and drop dead.

In the past two weeks, I've applied for a half dozen jobs that I fit to a very close fit. All are local. But in a number of interviews, outrageous claims of mismatches occur. And at least two agencies have confided in private that the effect occurs with many of their clients. "It's reverse discrimination. You're a white, middle-aged guy who knows what he's doing and the industry is driven by the profits of prolonged, over-staffed, other-sourced projects - many in one stage of failure or another all over Hartford."

The issue that Gates and his disciples skirt is that the people like myself who evangelized his products to begin with are being ruthlessly thrown under the bus. He won't lose a wink of sleep over that but I do.

But his replacement workers are not cheaper or more desirable. In a recent Courant article, families of these workers often have no health insurance and leave behind expensive health care bills for tax-payers to assume. And educating children of fluid populations taxes the ability of school boards to plan expenses, enrollments, and staffing.

I wish Gates would hire unemployed Americans long before importing legions of "highly-skilled" workers. While these workers may be cost-effectively skilled they often lack the cultural sensitivity and ethical fortitude to understand American values and freedoms. When American workers are discriminated against in their own country as a new American underclass caste then I think we need to wake up.

The cost of American education no matter how you slice and dice the numbers means that a college graduate needs to make a professional salary to pay that cost back. H-1B visa workers bear no such burden. Bill Gates might want to run the numbers through his spread sheet again before trying to starve off what's left of us. We don't deserve being kicked while we're down.

This country has a rich technical workforce and Bill Gates should put it to work instead of knee haul it.

Dramatic Math Gains - Add It Up...

Jay Matthews of the Washington Post relates the formula a 24 year old teacher used to dramatically improve the scores of some poor students.

From "New Teacher Jolts KIP" by Jay Matthews
"I've found that most traditional textbooks oversimplify and isolate concepts, and yet, are still too difficult for non-readers to use. They don't generally push students to think, but offer repetitive, and boring, practice," she said. She started writing each lesson nightly. This was a remarkable feat of youthful energy when you consider that KIPP teachers work 10 hours a day, and Suben was putting in another three hours each night at home composing the next day's lesson on her Dell laptop.

Suben said: "My primary goal as a teacher is to help my students understand the reasoning behind math rules and procedures. I have several core beliefs about this: (1) Understanding is constructed by the learner, not passively received from the teacher. (2) Understanding is built by making connections between as many strands of knowledge as possible. (3) Understanding is galvanized through communication. (4) Understanding is only valuable when you reflect on it and question it."

The core of her method is the workbook she produced last year on the fly. It "lets students build their own notes and create their own examples. It is incredibly active learning," she said. They were encouraged to write down the meaning of important terms and strategies they used that worked with certain kinds of problems.

"I certainly refer to traditional textbooks for ideas and guidance as I write," Suben said. "My sequence and pace are set by a long-term plan that I have designed to catch the students up on second-, third- and fourth-grade material as well as introduce every single D.C. public schools fifth-grade standard by testing time. I model my word problems after the eighth-grade text that I used in Louisiana because those problems require the level of understanding that I am looking for. I focus on non-traditional problems so that students are forced to think."


Thinking! Isn't that a violation of the No Child Left Behind Law?

Refreshing Educational Insight on Teaching Algebra

In today's Courant and article talks about an educational philosophy that the NCLB cancer is trying to stomp out. It's entitled; Johnny's Lessons - How A Tough Kid Found Key To Mystery Of Math: Multiplication - February 19, 2006 by Karin Klein.

Read the whole thing, it will bring tears to your eyes. Ms. Klein was asked to tutor a boy who was failing Algebra. She recalls that experience in responding to the LA Times recent series quoted earlier in this blog. Educational commentary is rarely better stated than in this piece.

"Today's failing high school students, though plagued by more poverty and upheaval than Johnny or I ever knew, bring the same scanty skills to algebra class, according to the Times' series. They never quite grasped multiplication tables, but still they moved on to more complicated math.

Who can focus on the step-by-step logic of peeling back an equation until "x" is bared when it involves arithmetic that comes slow and slippery, always giving a different answer to the same calculation?

Yet in all these decades, the same school structure that failed Johnny goes on, dragging kids through the grades even if they don't master the material from the year before. This especially makes no sense for math, which is almost entirely sequential.

Leaving children back isn't a solution; it simply makes them feel stupid. They learn, like Johnny, to look at the floor. The floor can't embarrass them.

What I learned from Johnny - aside from the fact that greasers could be sweet-natured and very, very smart - is that schools are structured to help administrators feel organized, not to help children learn.

Young children's skills are all over the map, yet we corral them into second grade, third grade and so forth, where everyone moves at one pace in all subjects. Better to group them according to their skills in each subject, without the "grade" labels, and let them move on to the next skill when they have mastered the one they were on. If they're not getting it, give them extra tutoring, but don't push them forward until they're ready. This way, there is no failure - only progress.

It requires a sea change in thinking, but it's not impossible or even all that hard. Back before standardized tests put classes in lockstep, some progressive schools already were using team teaching to do this in math as well as reading and writing."

A mathematical fable

In an article called, More Training Is Seen as Key to Improving Math Levels by Diana Jean Schemo in the New York Times, Bush's proposal to -cough- help math and science education is to get volunteers to do the teaching.

...he called for 30,000 mathematicians and scientists to pitch in as adjunct teachers, to teach a course at their local public schools.


That's where my story starts. My sons play basketball and we taxi them around quite a bit and every once in a while I get to the gym and some players are hanging out late at the gym with the coaches.

So one day I arrive a little early and Ron Pires, the Varsity basketball coach says to the squad, "Okay, listen up! We're going to shoot free throws [and he gives them certain parameters to follow] AND! - I WANT THE GROUP AS A WHOLE TO MAKE AT LEAST 85% OF YOUR SHOTS."

From the distance of the sidelines, an almost perceptable breeze seemed to push back the hair on the players heads - kind of like that rock and roll speaker advertisement of a kid listening to music in a wind tunnel. Ron repeated, "85% gentlemen."

At every basket, a group formed and began the exercise - for those who aren't basketball fans, 85% is a mighty fine shooting percentage and this was a test.

Once the shooting exercise was over, everyone gathered around Coach Pires who began asking for results.

"How many made four out of four?" Say five players raised their hands. "Five times four is how many baskets?" "Twenty" was answered by a chorus of players.

"Alright, how many made 3 out of four?" Now three players raise their hands. "So how many shots is that?" And so it went. Coach Pelletier rushed to get a calculator.

But what I witnessed from the sideline looked very much like a Norman Rockwell painting. Here in the middle of a gym were the biggest students in the school rubbing their chins, raising their eyes to imagine a calculation on a non-existent whiteboard, scatching their heads like Stan Laurel pondering an impossible dilemna. It looked like a lot of thinking and had I captured it on film it would be the yearbook photo.

And in the same fashion that they win basketball games, they helped each other track and recalculate the necessary arithmetic - IOW, with teamwork. The image is still stuck in my memory because everything you ever needed to know about teaching math was right there.

Which brings me back around to a number of things.

A.) Feed these students math in non-threatening, appropriate doses and they learn. You don't need tests to see the gears working when the learning is obvious.

B.) Students working in teams to supplement each other's efforts works well. A lot better than "every student for themselves" no matter what - we got tests to - ahem - administer!

C.) You don't need mathematicians and scientists to walk in from the street to teach math. And, we aren't even touching the subject of what would qualify these people to be in classrooms with mixes of students with mixes of needs. Math is taught and can be taught in doses in many school activities that already exist. Students need to be given a weighed credit for the math and english they exercise in other classes that counts toward graduation.

D.) Bush's "plan does not envision hiring new teachers. Rather, it proposes to retrain the math and science teachers on hand." That's very nice but if the teachers receiving more training are hopelessly poor teachers to begin with - unmotivated to learn new techniques, self-centric, experts in math and ignorant of learning - we're just throwing good money after bad. Schools need a plan to marginalize mediocrity and reward talent.


BTW; The team made exactly 85% of their shots that evening.

The problem with Math

I've been attending curriculum meetings because that's my special interest. I've taught at every level if only briefly and over the past thirty years much of my computer science career has been dedicated to automating manual or ineffective business processes.

Now, I am not actually ON the curriculum committee but that's a whole other story.

The point of this post really is that I strongly felt that EO Smith was academically doing a pretty good job of educating our kids. At face value this seemed to be the case. The more exposure I have to the teachers and curriculum the less enamored I am with what I seeing and hearing.

Lately there's a push to force MORE math as a prerequisite for graduation. We had a lively discussion on the subject. The math department continues to disappoint me in their offerings (more about that in a future posting).

But the decision about math was put on hold for want of more information. The LA Times series we read yesterday continues talking about California's experience with the genre:

The course that traditionally distinguished the college-bound from others has denied vast numbers of students a high school diploma.

"It triggers dropouts more than any single subject," said Los Angeles schools Supt. Roy Romer. "I think it is a cumulative failure of our ability to teach math adequately in the public school system."

When the Los Angeles Board of Education approved tougher graduation requirements that went into effect in 2003, the intention was to give kids a better education and groom more graduates for college and high-level jobs. For the first time, students had to pass a year of algebra and a year of geometry or an equivalent class to earn diplomas.

The policy was born of a worthy goal but has proved disastrous for students unprepared to meet the new demands.

In the fall of 2004, 48,000 ninth-graders took beginning algebra; 44% flunked, nearly twice the failure rate as in English. Seventeen percent finished with Ds.

In all, the district that semester handed out Ds and Fs to 29,000 beginning algebra students — enough to fill eight high schools the size of Birmingham.

Among those who repeated the class in the spring, nearly three-quarters flunked again.

The school district could have seen this coming if officials had looked at the huge numbers of high school students failing basic math.

Lawmakers in Sacramento didn't ask questions either. After Los Angeles Unified changed its policy, legislators turned algebra into a statewide graduation requirement, effective in 2004.

Now the Los Angeles school board has raised the bar again. By the time today's second-graders graduate from high school in 2016, most will have to meet the University of California's entry requirements, which will mean passing a third year of advanced math, such as algebra II, and four years of English.


furthermore...

"If you want to believe you're for standards, you're going to make kids take algebra. It has that ring of authenticity," said Robert Balfanz, an associate research scientist with the Center for Social Organization of Schools at Johns Hopkins University in Baltimore. "But you're not really thinking through the implications. There may be no good reason why algebra is essential for all high school students."


What we are beginning to examine here is education policy run amok. Politicians and overpaid administrative zealots are cheered for advocating ever higher and tougher standards as our children are sacrificed to this nonsense - a generation of unwitting sheep being led to educational slaughter.

We have got to re-evaluate what we're doing and no question is too obvious to ask. The more anyone truly examines the devastating after affects of NCLB and its zealot army of fools the more one remembers an old NAACP homily, A mind is a terrible thing to waste. Except these days we are witnessing with quaint disregard the wasting of generations of students to whom the love of learning and the tools of intellect are being systematically destroyed nationwide.

And, as the bad joke goes, our school is contemplating following the lemmings over that same cliff.

Connecticut has to wake up. This is the Land of Yankee Ingenuity for cripes sakes. Why are are schools dissolving into idiocy? At EO I'd like the Board to re-evaluate our math program and re-calibrate it to the needs of the community and students and I'd like to see the State Department of Education get out of the way and let some schools re-vitalize their curriculum including Region 19.

Can the legislature put a moratorium on NCLB? Get this educational policy cancer off our backs.

Quality Control, Growing Teachers, and Xenophobia

A most interesting New York Times Editorial post on improving education. Well worth clicking on the link for the full text. Here's an appetizer;


Why the United States Should Look to Japan for Better Schools

By BRENT STAPLES
Published: November 21, 2005

-snip-

The No Child Left Behind Act, passed four years ago, was supposed to put this problem on the national agenda. Instead, the country has gotten bogged down in a squabble about a part of the law that requires annual testing in the early grades to ensure that the states are closing the achievement gap. The testing debate heated up last month when national math and reading scores showed dismal performance across the board.

Lurking behind these test scores, however, are two profoundly important and closely intertwined topics that the United States has yet to even approach: how teachers are trained and how they teach what they teach. These issues get a great deal of attention in high-performing systems abroad - especially in Japan, which stands light years ahead of us in international comparisons.

Americans tend to roll their eyes when researchers raise the Japanese comparison. The most common response is that Japanese culture is "nothing like ours." Nevertheless, the Japanese system has features that could be fruitfully imitated here, as the education reformers James Stigler and James Hiebert pointed out in their book "The Teaching Gap," published in 1999.

The book has spawned growing interest in the Japanese teacher-development strategy in which teachers work cooperatively and intensively to improve their methods. This process, known as "lesson study," allows teachers to revise and refine lessons that are then shared with others, sometimes through video and sometimes at conventions. In addition to helping novices, this system builds a publicly accessible body of knowledge about what works in the classroom.

The lesson-study groups focus on refining methods that improve student understanding. In doing so, the groups go step by step, laying out successful strategies for teaching specific lessons. This reflects the Japanese view that successful teaching is the product of intensive teacher development and self-scrutiny. In America, by contrast, novice teachers are often presumed competent on Day One. They have few opportunities in their careers to watch successful colleagues in action. We also tend to believe that educational change would happen overnight - if only we could find the right formula. This often leaves us prey to fads that put schools on the wrong track.

There are two other things that set this country apart from its high-performing peers abroad. One is the American sense that teaching is a skill that people come by naturally. We also have a curriculum that varies widely by region. The countries that are leaving us behind in math and science decide at the national level what students should learn and when. The schools are typically overseen by ministries of education that spend a great deal of time on what might be called educational quality control.

-snip-

Faced with lagging test scores and pressure from the federal government, some school officials have embraced the dangerous but all-too-common view that millions of children are incapable of high-level learning. This would be seen as heresy in Japan. But it is fundamental to the American system, which was designed in the 19th century to provide rigorous education for only about a fifth of the students, while channeling the rest into farm and factory jobs that no longer exist.

The United States will need a radically different mind set to catch up with high-performing competitors. For starters we will need to focus as never before on the process through which teachers are taught to teach. We will also need to drop the arrogance and xenophobia that have blinded us to successful models developed abroad.

Ashford Democrats send the State a message

At the recent Democratic Town Committee meeting, State House Representative Mike Cardin updated the committee on legislative news from the State Capitol - emminent domain, identity theft, and more. However, the conversation soon turned to job creation and tax relief for small towns.

A recent Face the State program discussed CT's economy in unflattering terms.

...a new study warns that other states are growing much faster, and Connecticut is losing ground, in many key areas that affect business development and job creation.


The legislature should pay urgent heed to this discussion. The issue of tax relief for small town Connecticut is not far behind in importance.

Massachsetts is facing a similar situation and here is what Romney recently suggested,

Underlining the challenge, Romney said leaders of one technology firm in Massachusetts anticipated that 90 percent of its skilled labor would be in Asia in 10 years. He also pointed to statistics that show the United States graduating only 4,400 mathematics and science PhDs each year compared with 24,900 math and science PhDs for greater Asia.

"China and India have a population a multiple of ours. They have natural resources. There is no reason they can't emerge as the superpower. The only way we can preserve that role for ourselves is through innovation. It's erroneous that we do high-level work here and send low-level work abroad. When our market is no longer the largest market in the world, the idea that we're going to be innovating and they're going to be copying is erroneous," Romney said.

In response to the looming crisis, Romney pointed to some specific problems and proposed some remedies. He said we must close the educational achievement gap between racial groups in the United States. "The education gap is the civil rights issue of our age." He also said all U.S. students must raise their standing compared with students in other industrialized countries. According to one study, U. S. students rank 25th out of 41 industrial nations. "Fewer and fewer are performing at the top level," he said.

He suggested paying teachers a $5,000 bonus for teaching Advanced Placement courses, as well as giving the top third of teachers a $5,000 bonus. He also suggested a bonus for teachers that teach in troubled school districts. Romney also favored giving secondary school students laptop computers.

He pointed to some educational achievements in Massachusetts, where fourth graders ranked first in the country in math and English. He also noted that Massachusetts students ranking in the top fourth of their class can attend state institutions tuition-free under a scholarship program he supported.

"I want to make sure that Massachusetts remains competitive." Speaking of the nation, he said, "I want the center of technology and innovation to remain here. I am overwhelmingly optimistic about our ability to rise to the occasion."


Connecticut needs to wake up.

I also want to thank Mike for sending a warm congratulations letter on my election to Region 19. I hope not to let anyone down.

America's Being Left Behind

In a New York Times article titled: Are U.S. Innovators Losing Their Competitive Edge? by Timothy L. O'Brien published: onNovember 13, 2005, we are being warned about what is happening to our country as a result of the current administration of this country.


see: http://tinyurl.com/bjztc


"A COMMITTEE of leading scientists, corporate executives and educators oversaw the drafting of the report, entitled "Rising Above the Gathering Storm: Energizing and Employing America for a Brighter Economic Future." To spur American innovation, it recommends enhanced math and science education in grade school and high school, a more hospitable environment for scientific research and training at the college and graduate levels, an increase in federal funds for basic scientific research and a mix of tax incentives and other measures to foster high-paying jobs in groundbreaking industries. The report cites China and India among a number of economically promising countries that may be poised to usurp America's leadership in innovation and job growth.


"For the first time in generations, the nation's children could face poorer prospects than their parents and grandparents did," the report said. "We owe our current prosperity, security and good health to the investments of past generations, and we are obliged to renew those commitments.""


This is important information. Technology leadership is often measured in just a matter of weeks or months. This concern about the threats that China, India, and other even less friendly countries pose is very real in the software community that I work in and software is just one field of many in danger.


The article goes on to say,


"Mr. Flemings said that private and public capital was not being adequately funneled to the kinds of projects and people that foster invention. The study of science is not valued in enough homes, he observed, and science education in grade school and high school is sorely lacking.


But quantitative goals, he said, are not enough. Singapore posts high national scores in mathematics, he said, but does not have a reputation for churning out new inventions. In fact, he added, researchers from Singapore have studied school systems in America to try to glean the source of something ineffable and not really quantifiable: creativity.


"In addition to openness, tolerance is essential in an inventive modern society," a report sponsored by the Lemelson-M.I.T. Program said last year. "Creative people, whether artists or inventive engineers, are often nonconformists and rebels. Indeed, invention itself can be perceived as an act of rebellion against the status quo.""


Let's emphasize something important here. For all the phony rhetoric about American education falling behind the rest of the world, we find out over and over that that hasn't been true. The rest of the world is very good at administering perfunctory education but they look this way to figure out why it isn't working.


We know why. We have got to take back the education system from those who would turn our kids into test-taking-automotons and return it to the individual development of our children.

Instead of a Boston Tea Party, let's send these unnecessary tests to FEMA until they fill in the New Orleans low land. We have got to celebrate Yankee ingenuity all over again. This is not a time to politely debate nonsensical arguments, it's a time to free the schools of unnecessary testing and fraudulent school accountability exercises - it is killing the country.
