Gleanings from the Alternative Fact-World of Betsy ‘Checkbook’ DeVos

Your first installment from the pearls of wisdom from the perennial purchaser of politicians, Betsy ‘Checkbook’ DeVos:

Maybe we should look at the actual graduation rates for DC public and charter schools, courtesy of the DC Office of the State Superintendent of Education, or OSSE:

Here are the official 4-year graduation rates for 2016:

hs-graduation-rates

hs-graduation-rates-part-2

 

I highlighted some of the schools. The pink ones are the five DC charter high schools where the graduation rate is decidedly BELOW 70%. The orange ones are the ten (10) regular DCPS high schools where the graduation rate is decidedly ABOVE 70%.

(This is not counting two DC charter schools that closed for extremely low performance or for wide-spread theft by their founders.)

(Full disclosure: my own children graduated from Banneker and School Without Walls some years ago. Notice what the graduation rates are from those two schools.)

Also, notice that the overall graduation rates from the regular public high schools in DC (69.0%) and from the DC charter school sector (72.9%) are not all that different. And that’s even though the charter schools can and do push out students to the regular public schools. This is also despite the fact that to get into a charter school, students have to have parents or guardians who can navigate the application process — and we have a lot of students here in DC where the parents are ‘MIA’.

I will also let you look at the official four-year graduation rates by the various subgroups (by gender, ethnicity, and so on). Once again, you will not see the huge disparities claimed by Billionaire Betsy between graduation rates in the regular DC public schools and in the charter schools. [There is one large disparity: the number of white, Asian, or multi-racial students in the DC charter high schools is tiny; they are almost all in the regular DC public schools!]

So, I guess we can expect lots more ‘alternative facts’ from Billionaire Betsy, just like we have gotten used to seeing them coming from Marmalade Mussolini, aka #45.

 

Who judges whether a reform is a success or not in education?

Excellent question, posed by Larry Cuban, on the case history of the once-widely-celebtrated Gary Plan for education.About 100 years ago, its blend of manual and mental training, along with night schools for recent immigrants, was seen as a marvel and widely copied. Now nobody remembers it even existed, partly because of how they defined ‘success’, according to Cuban. Here’s the link

I’ve certainly noticed that if you ask people about any sort of reform, you NOT necessarily find agreement. I have spoken to Turks who vehemently deny that there was any sort of systematic genocide of Armenians roughly a century ago, and Chinese who deny that anything bad is happenig in Tibet. There are even people who defend the memory of Genghis Khan, Franco, Hitler, Mao, Stalin, and the KKK!

 

Accountability and Following the Law in DC Education

Valerie Jablow has yet another well-researched column on how the laws on accountability and transparency are NOT enforced in the education sphere in DC, especially for charter schools. I highly recommend reading and digesting it, and then figuring out how to act on her recommendations.

 

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.

What Lessons Has DC Drawn From PISA?

Basically, the lessons drawn by those in charge of education in Washington, DC, is to do exactly the opposite of everything being done by nations with high test scores. Valerie Jablow at EducationDC explains the details.

L.A.Times Reporter Might Have Messed up the Math — Will the Ancient Astronomers Come to the Rescue?

WOW!

You won’t believe the revolutionary discoveries that modern astronomers have found, by carefully decoding old astronomical tablets written on tablets, in cuneiform, as long ago as 700 BC in modern-day Iraq!

You might not be surprised that a science reporter and various commentators reporting on the story – including myself – may have got the math wrong.

This is not just clickbait – the historical research was very dedicated and quite clever, and it shows that all the  years I’ve tried to to study and learn Arabic, astronomy, Babylonian, calculus, Chinese, French, geometry, Hebrew, Latin, mathematics, Russian, Spanish and Turkish might actually pay off one day, when I grow up! (*)

What’s the scoop?

In a nutshell: Researchers read and translated a bunch of ancient and more recent records of eclipses of the Sun and Moon, from cultures all over the world, over a period of 27 centuries. They compared those results  with what modern software and computers calculate they should be if you simply went backwards in time at a rate of precisely 24 hours per day. That meant studying lots of obscure records written in Chinese, Babylonian, Arabic, and Latin, as well as in modern languages.

The researchers were quite impressed at how accurate the Arab and Chinese records were, even though their instruments were much cruder than what we have today. (Obviously, no telescopes, no electric clocks, etc, etc…) The records from the Roman empire and early Mediaeval Europe, however, are apparently not nearly as good (200 BC – 600 AD) as the Chinese and Arab ones were.

cuneiform-astronomy

After the invention of the telescope a bit over 400 years ago, records became much richer. For example, observers could record the time, to the second (or even better), when a star would get blocked out by the Moon and then eventually re-appear on the other side.

(David Dunham , though retired, is an expert on this.)

Bottom line, according to the newspaper reporter: If it’s noon right now, and you could somehow go back in time precisely twenty-five centuries ago to exactly where you are standing or sitting, then everybody else back then (about 500 BC) would see the time as the equivalent of 7 PM, because the earth is turning on its axis ever so slightly slower today.

Revolutionary, I told you! Not joking, not exaggerating either!

But wait a second – how much would that be slowing down per year? The article doesn’t spell it out, but 7 hours is 420 minutes, or 60*420 = 25200 seconds,. If we divide that by about 2500 years, you get 10 seconds per year!

Wait a second, that doesn’t sound right at all! These days, if the earth really got slower at a uniform rate of 10 seconds per year, many of our cheap quartz watches and clocks are so accurate that we would actually notice the difference!

Let’s go back. The LATimes reporter, Deborah Netburn, wrote:  “the amount of time it takes for Earth to complete a single rotation on its axis has slowed by 1.8 milliseconds per day over the course of a century” – which is not very clear.

A commenter on LATimes website, named “It is me Here” wrote:

The time discrepancy described as “It may not sound significant, but over the course of 2½ millenniums, that time discrepancy adds up to about 7 hours” is not 7 hours. Over 2500 years it amounts to: 1.8 (milliseconds) x 365 (days per year) x 2,500 (years) = 1,642,500 milliseconds, that equals 1,642 seconds that equals 27.38 minutes, not 7 hours.

 

Did you get that, and do you agree? If not, let’s go back a little further, to the  abstract of the original study report which says:

New compilations of records of ancient and medieval eclipses in the period 720 BC to AD 1600, and of lunar occultations of stars in AD 1600–2015, are analysed to investigate variations in the Earth’s rate of rotation. It is found that the rate of rotation departs from uniformity, such that the change in the length of the mean solar day (lod) increases at an average rate of +1.8 ms per century. This is significantly less than the rate predicted on the basis of tidal friction, which is +2.3 ms per century.

(my emphasis – gfb)

 

So, would we really be 7 hours slow if we went back?

Maybe, maybe not.

Let’s think about it differently:

Since 500 BC, it has been about 25 centuries. According to the study, every century the earth slows down by about 1.8 milliseconds, which isn’t very much. 25 * 18 milliseconds is 450 milliseconds, which is a bit less than half a second. So does that mean we have to add up all of those 1.8 milliseconds by 365 days

That’s not much at all.

(BTW, why does the earth get slower? One source of the slowing down is simply the friction of the ocean tides. If you’ve ever been to the ocean and paid attention, you know that the gravitational pull among the Sun, Earth and Moon raise and lower a WHOLE lot of water all over the world, twice a day. That takes a HUGE amount of energy and a lot of it is dissipated in friction, which slows things down. But there are others.)

But here is a different way of looking at it still, as a trapezoid: the left-hand parallel side is about one-half second shorter than 24 hours – the length of a day in during ancient Babylonian days. The right hand parallel side is exactly 24 hours long. In between, there are 2,500 elapsed years.

Let’s pretend that each of those years contains 365 days (let’s agree to ignore the effect of leap years for right now). If the shape were a rectangle, then that would mean that the earth had not slowed down at all, and if you went backwards in time from now by 2500 years it would be exactly the same date, same time.

slowing-of-length-of-day

Apparently, it’s not. The lost or extra time is the part I show in this next diagram:

slowing-of-length-of-day-2

 

That little pink section is a a long skinny triangle with its right hand end 1/2 second per day long, and the base is 2500 years long, or 912,500 days. The area of a triangle is 1/2 * base * height, and so we use 1/2 * 1/2 * 912,500 and get 228,125 seconds lost (the ‘days’ units cancel out), or about 3802 minutes, or 63 hours, 22 minutes, which is 2 days, 15 hours, and 22 minutes off.

Not sure if I’m right or not, but would appreciate comments.

Here is one of the figures from the paper:

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.

 

 

“Schools Matter” on Democrats’ Public School Betrayal

Jim Horn (I think) here excoriates the heads of the AFT, NEA and Diane Ravitch for helping sell out public school students, their families and their teachers to the corporate and financial oligarchs. Is he going overboard?

I know for a fact that Randi Weingarten is playing a very complicated double game: she personally negotiated the terrible contract in DC that started the give-back of pretty much all teacher rights in return for a mythic ally high salary that very, very few teachers will ever stick around to collect.

Is Horn going too far? Read it, and comment. I’m posting the whole thing.

Schools Matter

DeVos Will Make Democrat’s Charter Plan Easier to Sell

Posted: 05 Dec 2016 07:55 AM PST

A few years back Diane Ravitch was forced to admit openly what the opponents of testing accountability knew when No Child Left Behind became law: the ridiculous goal of 100% percent student proficiency in reading and math could never be met, and the fanciful imposition of such a pipe dream would wreak havoc across the entire K-12 education universe.

.

By the time Ravitch finally came around to acceding the dangerous fantasy that she had loyally promoted along with her fellow charter and voucher supporters at the Hoover Institution, almost half the schools in the U. S. had already been labeled as failures, and a reckless and corrupt corporate feeding frenzy had been set into motion by Ravitch’s free market chums. Tutoring companies were draining billions in federal dollars by cramming poor children for tests they would never pass; the scandal-ridden Reading First gang was shoving its antiquarian reading techniques nationwide to really bad effect; alternate teacher certification scams had been federally incentivized; charter schools, both virtual and physical, were springing up like mushrooms in cow paddies after a rain, and a whole new industry of sponsored fake education research by corporate foundation “think” tanks had become an acceptable occupation for under-employed academics.

.

During the seven years since Ravitch’s lucrative conversion experience, Diane has made it clear that she maintains one foot solidly on the side of the corporate education reformers who brought us the NCLB disaster. It took her until 2013 to admit her stubborn wrongheadedness on Common Core, even while maintaining even today her support for “voluntary” national standards–whatever that means. Today she maintains her enthusiasm for shoveling Core Knowledge into the heads of children, just as she remains a supporter of ridiculously high NAEP standards that have been used by “reformers” for years to bludgeon the public schools for their low scores.

.

In early 2015, her crucial support for NCLB 2.0, which is better known as ESSA, made her culpablility undeniable. This was followed by a year of propagandizing for the longtime charter supporter, Hillary Clinton, while pretending to be the most determined foe of school corporatization. Diane’s blog was used to soft-pedal Weingarten’s autocratic choice of Clinton over Sanders, just as it was used to obfuscate Hillary’s supportive position on corporate welfare charters. And it was her political soulmate, Randi Weingarten, who put the final flourishes on the Democratic platform, which clearly supported charter schools while pretending to do the opposite.

.

Her recent outlining for Jay Mathews the kind of charter schools she would support signals that she is ready to swing both legs onto the side of the charter fence. Along with the NEA’s Eskelsen, AFT’s Weingarten, and the troglodytes running the DNC, Ravitch is clearly signaling surrender on charters to Team Trump, even before the first inaugural dance.

.

Ravitch, as lead propagandist for the corporate unions, will use the Betsy DeVos nomination to make the Dem position of supporting “non-profit” segregated no excuses charters seem most reasonable in comparison. It is not a coincidence that Ravitch is suddenly playing footsie with charter spokesman, Jay Mathews.

.

The ESSA, which could not have happened without NPE, NEA, and AFT support, will continue intact, thus allowing Trump, too, to appear reasonable in letting public schools die a slower death than Sister Betsy would have preferred. And thus the bipartisan dismantling of public education is likely to continue on schedule. The biggest change we are likely to see in Washington are the corporate Democrats from the Gates Foundation heavily reinforced by the corporate Republicans from the Walton Foundation.
Oh yes, don’t forget to send your next donation to NPE. Ravitch and the corporate unions need your support to buy a whole new coat of whitewash.

Aaron Pallas Asks: What’s the Worst that can Happen With Betsy Devos as Education Secretary?

He gives two possible scenarios. The first one is pretty friggin’ bad. I won’t give any details, but I think there are plenty of other really bad scenarios that he didn’t consider. Can you think of any, after reading his take?
