Compare ‘Education Reform’ to Ineffective but Profitable Quick-Weight-Loss Schemes

John Viall compares the past 15 years of education ‘reform’ to the past 30 or 40 years of completely counterproductive weight-loss schemes — in both cases, the results are exactly contrary to what they were promised to be. In one case, we can see that America’s obesity rates are some of the worst in the world. In the other, we have certainly not ‘raced to the top’ on TIMMS, PISA, or any other international test, despite all of promises by both the Bush and Obama administrations.

He concludes (I added some color):

“For a sixth time the PISA test was administered in 2015.

Now, 15-year-olds from seventy countries and educational systems took the test. How did U. S. students fare?
The envelope please.
In reading U. S. students scored 497. In other words, after fifteen years of school reform and tens of billions wasted, reading scores were still down seven points.
Fifteen years of listening to blowhard politicians—and U. S. students averaged 470 in math, a depressing 23-point skid.
Surely, all that meddling must have done some good? No. Science scores averaged 496, still down three points.
Fifteen years of diet plans that couldn’t possibly fail and, metaphorically, we were all just a little more fat.
PISA scores had been the foundation on which all school reform was built; and after all these years, America’s 15-year-olds were scoring 33 points worse.

If US Students Are Doing Worse After 15 Years of Test & Punish (NCLB, RTTT, ESSA, etc), Then By All Means Do It Harder and More Vigorously!

You probably saw the results that American students actually did a little worse than in previous years on the international math/reading/science test known as PISA, and are falling behind their international peers. If you didn’t, here are a few links: here, here, and here.

If you’ve been paying attention, you’ve probably noticed that since 2001, the American public education system has been laboring under various ridiculous laws like ‘No Child Left Behind’ which mandated that by 2014, every single student in every single subgroup in every single school would magically become ‘proficient’ on American tests that are similar to PISA, or else their teachers and administrators would be fired, the schools would be shut down, and their education would be turned over to private charter operators.

Of course, not all American students became magically proficient – that was not possible, just like not everybody can run a 5 or 6 minute mile, no matter how many coaches you fire. However, many, many schools were shut down, many teachers and principals were fired, and private charter operators have taken over the profits from educating more and more students.

Two states stand out from the rest: Michigan and Massachusetts.

Michigan, the home of incoming EdSec Betsy Devos, has turned over the education of its poorest students to lots of charter and voucher schools — and if you look at the results, they are terrible. Detroit appears to be the worst of all cities tested, in fact. (See graph below) Therefore, she (and many other ‘reformers’) want to extend those efforts to all 50 states.

Massachusetts, however, has a serious cap on the number of charter schools. Its citizents recently voted down a proposal funded by people like DeVos to remove that limit and open up dozens of additional charter schools. May I add that Massachusetts has the highest NAEP scores in the nation? * And teachers who are generally union members? Quoting from one of the Post articles, our current secretary of education, who thinks that the solution to everything educational is more charters, more testing, more standards, and more vouchers:

“King pointed to Massachusetts, where students excelled on the PISA test, as an example of how states can get education right.”

In other words, if you do everything that King and Devos recommend, then you might guess that your test scores will go DOWN. If you do the opposite of what they recommend, then it looks like scores go UP.


  • Although Boston is not #1 in scores of all large separately-tested cities, Massachusetts as a whole is in fact #1 on the latest NAEP. Don’t believe me? Look it up here.



More on Rigging Elections

Now, let us suppose that somehow the Hillary campaign actually managed to

(a) make sure that a rigged coin – supplied by them, not taken from somebody’s pocket – was used in each of the six coin toss cases

(b) figure out in advance which caucuses had to get those coins

(c) tell their person which side of the coin to choose in case a toin coss came up,

(d) none of the other folks noticed any of this skullduggery taking place right in front of their eyes — (by the way, you should watch this video of how this worked in practice)

THEN, yes, that weighted coin might help their odds, as you can see in this chart:


I used the binomial theorem to figure this one out. Let me give a few examples: in the row that’s highlighted in green, the probability of heads and tails is both 50%, and as I indicated int he last post, the probability of getting ‘heads’ five times out of six is about 9.38%. However, if you could somehow figure out how to make a coin that came up ‘heads’ 60% of the time, then your chances of getting 5 heads would improve to 18.66%.

And if you could boost the unfairness of your coin to the point that it would come up heads 80% of the time then your chances of getting 5 ‘heads’ would be 39.37%. Still not a slam-dunk.

I only know of two ways to make a coin biased. One method is to carefully split two coins in half the hard way, and make a two-headed coin (or two-tailed) coin. Such coins are actually sold in magic shops.

The other method is to bend the coin slightly – I am told that the concave side will end up being on top more frequently (like a cup).

So, Hillary’s nasty minions would have had to either distribute a bunch of bent coins or two-headed coins, and nobody else would have had the brains or eyesight to notice, for this to have been rigged.

I don’t think so.

Who is responsible for most carbon emissions?

An article in Nature* profiles a meticulous researcher who has shown that a small handful of companies were responsible for the vast majority of all carbon emissions, and that well over half of those emissions happened since my own children were in elementary school. Scary.

“The result, peer reviewed and published in Climatic Change, showed that just 90 companies contributed 63% of the greenhouse gases emitted globally between 1751 and 2010. Half of those emissions took place after 1988—the year James Hansen of NASA testified to Congress that there was no longer any doubt that global warming had begun.”


(* Nature is the magazine of the AAAS (formerly known as the American Association for the Advancement of Science). Most of its articles are quite dry and technical descriptions of rigorous scientific experiments in every field that currently exists. It is not a propaganda sheet!)


Remedial College Courses and Real Problems

From a recent discussion on the Concerned4DCPS list about a recent NYT article on the numbers of students taking remedial courses at the college level. I have taken the opportunity to revise and extend my remarks. If you want to read these in chronological order, start at the bottom.


(From me:)

Judge in NY State Throws Out ‘Value-Added Model’ Ratings

I am pleased that in an important, precedent-setting case, a judge in New York State has ruled that using Value-Added measurements to judge the effectiveness of teachers is ‘arbitrary’ and ‘capricious’.

The case involved teacher Sheri Lederman, and was argued by her husband.

“New York Supreme Court Judge Roger McDonough said in his decision that he could not rule beyond the individual case of fourth-grade teacher Sheri G. Lederman because regulations around the evaluation system have been changed, but he said she had proved that the controversial method that King developed and administered in New York had provided her with an unfair evaluation. It is thought to be the first time a judge has made such a decision in a teacher evaluation case.”

In case you were unaware of it, VAM is a statistical black box used to predict how a hypothetical student is supposed to score on a Big Standardized Test one year based on the scores of every other student that year and in previous years. Any deviation (up or down) of that score is attributed to the teacher.

Gary Rubinstein and I have looked into how stable those VAM scores are in New York City, where we had actual scores to work with (leaked by the NYTimes and other newspapers). We found that they were inconsistent and unstable in the extreme! When you graph one year’s score versus next year’s score, we found that there was essentially no correlation at all, meaning that a teacher who is assigned the exact same grade level, in the same school, with very similar  students, can score high one year, low the next, and middling the third, or any combination of those. Very, very few teachers got scores that were consistent from year to year. Even teachers who taught two or more grade levels of the same subject (say, 7th and 8th grade math) had no consistency from one subject to the next. See my blog  (not all on NY City) herehere, here,  here, herehere, here, here,  herehere, and here. See Gary R’s six part series on his blog here, here, here, here, here, and here. As well as a less technical explanation here.

Mercedes Schneider has done similar research on teachers’ VAM scores in Louisiana and came up with the same sorts of results that Rubinstein and I did.

Which led all three of us to conclude that the entire VAM machinery was invalid.

And which is why the case of Ms. Lederman is so important. Similar cases have been filed in numerous states, but this is apparently the first one where a judgement has been reached.

The hard-to-kill lie that low-fat diets are good for you

In 1980, health authorities in the US and the UK issued food guidelines that urged people to eat less fat, less protein, less cholesterol, and more grains and other carbohydrate-rich foods.

People in general (including me) followed that advice, even though in hindsight it has become clear that there was absolutely no evidence that it would work. If you’ve been paying attention, 1980 was about the year that the problem of obesity became an epidemic in the US and in Great Britain. Proponents of a low-carb, higher-protein, low-sugar diet like John Yudkin or Robert Atkins were called all sorts of names by powerful figures in the American and British health establishments, in particular by Ancel Keys and his many acolytes. Yudkin in particular had is reputation besmirched, and Atkins was called a fraud.

Gary Taubes, Nina Teicholz, and Robert Lustig are some of the researchers and writers who have recently pointed out that the familiar low-fat hypothesis has no evidence whatsoever backing it up, and that there is lots of evidence contradicting it.

A few paragraphs from a recent article on this in the Guardian, which I urge you to read in its entirety:

Only in the last few years has it become acceptable to study the effects of Atkins-type diets. In 2014, in a trial funded by the US National Institutes of Health, 150 men and women were assigned a diet for one year which limited either the amount of fat or carbs they could eat, but not the calories. By the end of the year, the people on the low carbohydrate, high fat diet had lost about 8 lb more on average than the low-fat group. They were also more likely to lose weight from fat tissue; the low-fat group lost some weight too, but it came from the muscles. The NIH study is the latest of more than 50 similar studies, which together suggest that low-carbohydrate diets are better than low-fat diets for achieving weight loss and controlling type 2 diabetes. As a body of evidence, it is far from conclusive, but it is as consistent as any in the literature.


In 2008, researchers from Oxford University undertook a Europe-wide study of the causes of heart disease. Its data shows an inverse correlation between saturated fat and heart disease, across the continent. France, the country with the highest intake of saturated fat, has the lowest rate of heart disease; Ukraine, the country with the lowest intake of saturated fat, has the highest. When the British obesity researcher Zoë Harcombe performed an analysis of the data on cholesterol levels for 192 countries around the world, she found that lower cholesterol correlated with higher rates of death from heart disease.

In the last 10 years, a theory that had somehow held up unsupported for nearly half a century has been rejected by several comprehensive evidence reviews, even as it staggers on, zombie-like, in our dietary guidelines and medical advice.

The UN’s Food and Agriculture Organisation, in a 2008 analysis of all studies of the low-fat diet, found “no probable or convincing evidence” that a high level of dietary fat causes heart disease or cancer. Another landmark review, published in 2010, in the American Society for Nutrition, and authored by, among others, Ronald Krauss, a highly respected researcher and physician at the University of California, stated “there is no significant evidence for concluding that dietary saturated fat is associated with an increased risk of CHD or CVD [coronary heart disease and cardiovascular disease]”.

Many nutritionists refused to accept these conclusions. The journal that published Krauss’s review, wary of outrage among its readers, prefaced it with a rebuttal by a former right-hand man of Ancel Keys, which implied that since Krauss’s findings contradicted every national and international dietary recommendation, they must be flawed. The circular logic is symptomatic of a field with an unusually high propensity for ignoring evidence that does not fit its conventional wisdom.

Shortage of US STEM workers? High-Tech Companies Think Otherwise

In fact,

“Although employers often claim in public statements that shortages of domestic talent prevent them from finding workers, they tell a different story in filings to the U.S. Securities and Exchange Commission (SEC), Salzman noted. “Accenture states that restrictions on guest worker supply would result in ‘new or higher minimum salary requirements and increased costs.’ Another firm says they would have to ‘replace existing offshore resources with local resources, namely U.S. workers, at higher wages.’ That is, without the congressional discount for guest workers, the highly profitable IT industry would have to hire more U.S. workers and pay them more than guest workers.”

Demeaning treatment of a Texas science teacher

(From Nov 2014; this somehow never made it out to the blogosphere… It’s not original from me)

What this teacher is going through is the sort of mindless edumalarkey that is driving many excellent teachers out of the classroom. She has asked that her story be publicized.

The Educational Delusional Scheme by Dr. Denise Gordon November 22, 2014

I write this short essay to disclose what is happening within my own science classroom, I write to expose the demeaning work environment that I and my fellow colleagues must endure, and I write to give purpose to my years of acquiring the necessary skills and knowledge in teaching science for the secondary student. I am not a failure; however, by the Texas STAAR standard assessment test, I am since this past year I had a 32% failure rate from my 8th grade students in April, 2014. The year before, my students had an 82% passing rate.

What happened in one school year? It does not matter that 2/3 of the student population speaks Spanish in their home. It does not matter their reading capability could be on a 4th grade level. It does not matter homework never gets turned in and parent phone calls bring little results.

What does matter was that my students were required to develop a yearlong research project by stating a problem, thinking of a solution, designing the experimental set up, collecting the required data, and formulating a conclusion. Some of the projects were good enough to enter into the regional science fair. From a selection of thirty-five projects, twenty-four were sent to the regional science fair. Some of these projects won ribbons and a chance to go to the state science fair competition. Five of my students were invited to participate in the elite Broadcom Master Science Competition. No other 8th grader in my school district achieved this accomplishment. Other yearlong projects involved entering the Future City Competition sponsored by the IEEE.

My eighth graders had seven teams to compete and three came back with special awards. Another science competition for secondary students is eCybermission sponsored by the NSTA and the U.S. Army. My only team of girls who competed in this program won first place for the entire southern region of the eCybermission Competition.

Did any of my students get a thank you or congratulations from our school principal or the district about their science achievements? Sadly, the answer is a no. All I got was a call into the principal’s office at the end of the school year for the purpose of being pulled from teaching the 8th grade for the next school year due to my high failure rate on the state test. My students and I did receive two thank you letters from two community partnerships.

The Potters Water Action Group, represented by Richard Wukich and Steve Carpenter were thankful for our educational brochure that my students helped design for their water filtration project. Krista Dunham, Project Director of Special Olympics in Fort Worth, sent a thank you to my students for donating the soap box derby race money that my students organized and who built three scrap box cars for this worthy affair.

I am now being monitored on a weekly basis within my 6th grade classes and their posted grades. I am required to have a 15% failure rate. All assignments must be pulled from the district’s online teaching schedule; therefore, no soap box races or water brochures this year. I am not allowed to take any of my students off campus for data collecting.

Student project development does not flow well in the district school calendar, so I am being questioned by the principal about my scientific teaching philosophy. Action science with real world data is not on the district’s curriculum website. It does not matter that I have a Ph.D. in curriculum development. I must teach to the test since every three weeks all students will be taking a mandated district test. This means all teachers must review for the test, students take the test, and then we go over the test. That is three days out of fifteen teaching days dedicated to a test every three weeks.

Testing and retesting with documented lesson plans from the scheduled curriculum is what the district wants, but is it what the students need really to enjoy science?

Our test scores are posted online and evaluated by the administration. Our performance on these tests weighs heavily into our yearly professional evaluation. I have been placed on a “growth plan” due to the fact that I teach what my students should know rather than what the district has posted. I am somewhat a rebel or just set in my ways; however, this growth plan gives the new principal her leverage to remove me from this school. If I do not meet her standards on the growth plan at the end of the year, then I must be relocated to another school.

I teach my students math skills, writing skills, and research skills. I document this growth instead of monitoring their district test scores. I have been ordered to submit weekly announcements to the parent newsletter, but my submissions are deleted by the principal. I have been ordered to attend professional development at the level three tier within our district, but there is no level three offered because level three does not exist.

I have been documented that 100% of my students do not understand my lessons when I teach because I use “big” words. The 100% came from asking two or three students in the classroom by the principal when she did her bimonthly walk throughs. I have been pulled out of teaching class to be reprimanded on my poor teaching practices rather than wait for my planning time. I must lower my standards and give less work if I am to maintain a 15% failure rate. Is this what the parents want? Will this prepare the students for high school?

I can no longer incorporate the arts within my assignments since my activities do not come from the district’s website. The current push for STEM should be the banner to wave inside my classroom since I have been a secondary science teacher for the past thirty years; however, I could not and we should not trade the arts and music for pure technical science and math course work. Creative problem solving with visual displays or performing arts can be demonstrated instead of just technology and engineering skills. Language arts would implement the importance of writing and research instead of just writing a basic lab report.

When a student is allowed to decide on what he/she would like to study for their research project so many necessary skills are required. The student must speak and “sell” their project by presenting to outside judges at the regional science fair, designing skills are needed for the backboard, mathematical and technological skills are used for the data collection. The actual meaning of “science” comes from the Latin verb, scire, “to know” via knowledge gained by a study or a particular branch of study (Ayto, 1990). To know encompasses all topics of interest and that is why I teach science bringing in all areas of skills and interests for the student to develop. This is not found on the district curriculum website.

I want the student to be creative, to write, to sing, to explore, to draw, to decipher, and to act in order to gain “knowledge” through the sciences.
I firmly believe students should have a choice in their own curriculum of study, final assessment should come from a variety of skills displaying the student’s individual growth, and what is taught inside the classroom should be applied to help the local community and school partnerships.

My principal has cut my fifteen year commitment with community partnerships for the Fort Worth Botanic Gardens, Botanical Research Institute of Texas, and the Fort Worth Science & History Museum by not approving any of my bus requests. Action science does not exist. Science education lies only in the classroom and on the district’s website. This is the educational delusion I must work in; a science classroom that is data driven to the point of paralysis and where students no longer experience real world problem solving projects.

Retirement is my ticket out of this madness, but what will be the student’s ticket out?

Is there really a STEM shortage? And do we want to emulate China or Korea?

You have all heard the mantra that we don’t have enough young people studying STEM (science, technology, engineering and math), and that is the reason that so many Americans are doing poorly.  If you agree with this call, this article in the New York Review of Books might make you think about the subject differently.

A few important points:

(1) The United States graduates way more engineers and scientists every year than can ever hope to get a job in their fields.

(2) As a result, large percentages of STEM graduates do not work in their chosen field

(3) As part of their profit-maximization strategy, tech giants like Microsoft nonetheless encourage this glut of STEM applicants while at the same time complaining that they need to hire foreigners on H1B visas, who earn on average about 57% of what a similarly-qualified American worker makes.

(4) While many, many American high school students fully plan to go into a STEM field in college, many are discouraged by poor teaching at the college level — even the instructors at elite STEM universities like CalTech get low marks from their students. And many of the instructors are, in fact, themselves temporary workers, neither full professors nor having any hope of tenure…

(5) The article also looks at Korean and Chinese school systems. It is true that they are producing tremendous test-takers and lots of engineers. But do we really want our children attending day and night classes every night until 10 pm, and what would we do with all of those unemployed future engineers anyway?

A few excerpts from the article, which reviews several books and documents:

“A 2014 study by the National Science Board found that of 19.5 million holders of degrees in science, technology, engineering, and mathematics, only 5.4 million were working in those fields, and a good question is what they do instead. The Center for Economic Policy and Research, tracing graduates from 2010 through 2014, discovered that 28 percent of engineers and 38 percent of computer scientists were either unemployed or holding jobs that did not need their training

“The Bureau of Labor Statistics (BLS), in its latest Occupational Outlook Handbook, forecasts that by 2022 the economy will have 22,700 nonacademic openings for physicists. Yet during the preceding decade 49,700 people will have graduated with physics degrees. The anomaly is that those urging students toward STEM studies are not pressing employers to ensure that the jobs will be there. And as we shall see, the employers often turn to foreign workers for the jobs they have to fill.

“Among the high school seniors who took the ACT and SAT tests last year, fully 23 percent said that they intended to major in mathematics, computer science, engineering, or a physical or natural science. And those contemplating programs related to health made up another 19 percent. But something evidently happens between their freshman and senior years. By graduation, the number of students who start in STEM fields falls by a third and in health by a half. In engineering, of every one hundred who start, only fifty-five make it to a degree.
