Why public shaming of teachers is exactly what the corporate reformers want -- with nationwide implications for our public schools

The NYC teacher data reports were released on Friday; and it’s no surprise that Rupert Murdoch's  NY Post was the first out of the gate to name and shame a teacher with a low rating.  Sunday’s Post featured a photo of teacher at a Queens school, naming her and the school, with the headline, “The worst teacher in the city,” based on her TDR.  They also interview a parent at her school who says she should be fired.  

Expect this sort of thing to go on for weeks if not months – as the Post tries to publicly shame one teacher after another, plastering their photos in the paper, pursuing a virulent propaganda campaign to attack the union and eliminate teacher tenure. The only question remaining is how many other papers will follow suit and participate by naming names.  

A restraining order might be the only way to stop this -- given that teachers are not public figures and it is widely recognized that huge margins of error exist for these ratings.   

According to reporter Yoav Gonen of the NY Post, the DOE admitted at a press conference last week that the “average” error rate for a teacher's percentile ranking was 35 in math and 53 in ELA, with a maximum margin of error of 75 in math and 87 in ELA -- out of 100 points!  

And this does not even address the fact that with a different class of students, on a different day and/or a different test, the results could be significantly different; or that (of course) improving test scores only are one facet of what good teaching means.

Moreover, despite claims now from Walcott and other city officials that they had no choice but to release these unreliable ratings, this does not seem to have convinced reporters.  In fact, the DOE seemed eager for this exact scenario to occur.  See what Gonen tweeted about what the DOE said in court, arguing for the release of the TDRs: 

Beth Fertig of WNYC recounts what Joel Klein said, right before he left office to work for Rupert Murdoch:

Joel I. Klein, actively led the charge to release the ratings to the public when he was chancellor. Mr. Klein told WNYC during an “exit interview” in late 2010 that the teacher data reports were a valid measurement, despite the objections of educators.

Also check out the back story about the release of these ratings, from Anna Phillips of NYT/Schoolbook:

… Joel I. Klein, championed the reports’ release, telling reporters that he supported their publication by teachers’ names.

The Columbia Journalism Review reported that the Education Department’s press office went a step further, encouraging reporters to file Freedom of Information requests — known as foils — for the individualized reports. According to the Review article by Lynnell Hancock:
But the Department of Education had privately dropped hints to some reporters that their competitors had already submitted foils, some journalists countered. Suspicions had been raised when the department responded to the foils with uncharacteristic speed. Normally, such requests took months, with layers of negotiations, said Maura Walz, a reporter for GothamSchools.org, an independent online news service. This time, it was service with a smile. “The Department of Education wants this out,” said Ian Trontz, a New York Times metro editor. “They have a lot of faith in these reports. They believe they are trustworthy enough to educate and empower parents.”
Still, empowering parents had not seemed to be a top goal in the past for this administration. To the most skeptical reporters, it appeared as if the city was using them. 

And when the rankings were first created in 2008 as part of a pilot program to evaluate teachers, a then-deputy chancellor, Christopher Cerf, said it would be a “powerful step forward” to have the teacher measurements made public, arguing, “If you know as a parent what’s the deal, I think that whole aspect will change behavior.”
Though Bill Gates wrote an oped against the public release of the TDRs last week, it was too little and too late.  In fact, he and Arne Duncan supported the LA Times release of similar unreliable ratings in 2010, which named teachers with low ratings,  with Duncan saying,  "What's there to hide?" 

Indeed, he and Duncan have pushed relentlessly for states to create numerical teacher rating systems based at least in part on value-added student test scores.  The feds made this condition for states to be considered for Race to the Top funds and now,  in order to obtain a waiver from NCLB.  

So far at least 33 states are in the process of developing and implementing such systems – including NY state -- and more are caving in every day.  This Gannett article explains how the NY state teacher ratings will likely be FOILable and published for every public school teacher in the state – and the same may be true of nearly all public school teachers in the nation.  

Gates is also creating a national database to hold confidential teacher and student information, without their consent, to be operated by Wireless Generation -- owned by Rupert Murdoch of the NY Post. 

The Gannett article contains a quote from Andy Rotherham, leading corporate reformer and a member of the advisory board of the new Gates database center, arguing in favor of the release of the TDRs in New York City:
"....public ratings would level the playing field for parents who aren’t plugged in on the best and worst teachers. And districts might have to address community desires when making personnel decisions.'Would it help create more incentives to address personnel if you had this sort of pressure?' [Rotherham] said."

As a result of this public shaming, which does not exist for any other profession, teaching in our public schools may become even more a temporary way-station for recent college grads, who will teach for only one or two years until they decide on a career with more stability, more income, and more respect from society.  

Anyone with a real interest in the profession long term will likely opt  to teach instead at a charter school or private schools, which will be free from having to implement these highly unreliable and reductionist teacher evaluation systems and/or make them public.  

In this way, the corporate  reform crowd will have achieved their goal, while fatally damaging quality public education in this country – with our public schools will in future become the repository for only those students who cannot get into private or charter schools, especially those with special learning needs, physical disabilities, or  recent immigrants.   

Someone, please, tell me why I am wrong!  Quick!

Testing expert points out severe flaws in NYS exams and urges parents to boycott them this spring!

Many recent columns have pointed out the fundamental flaws in the new NY teacher evaluation system  in the last few days: by Aaron Pallas of Columbia University; Carol Burris, Long Island principal, education historian Diane Ravitch, (who has written not one but two excellent critiques) and Juan Gonzalez, investigative reporter for the Daily News.  All point out that despite the claim that the new evaluation system is supposed to be based only 20-40%  on state exams, test scores in fact will trump all, since any teacher rated "ineffective" on their students' standardized exams will be rated "ineffective" overall.

To add insult to injury, the NYC Department of Education is expected to release the teacher data reports to the media tomorrow -- with the names of individual teachers attached.  These reports are based SOLELY on the change in student test scores of individual teachers, filtered through a complicated formula that is supposed to control for factors out of their control, which is essentially impossible to do. Moreover, there are huge margins of error that mean a teacher with a high rating one year is often rated extremely low the next. Sign our petition now, if you haven't yet, urging the papers not to publish these reports; and read the outraged comments of parents, teachers, principals and researchers, pointing out how unreliable these reports are as an indication of teacher quality.   

Though most of the critiques so far focus on the inherently volatile nature and large margins of error in any such calculation, here in NY State we have a special problem: the state tests themselves have been fatally flawed for many years.  There has been rampant test score inflation over the past decade; many of the test questions themselves are amazingly dumb and ambiguous; and there are other severe problems with the scaling and the design of these exams that only testing experts fully understand.  Though the State Education Department claims to have now solved these problems, few actually believe this to be the case.

As further evidence, see Fred Smith's analysis below.  Fred is a  retired assessment expert for the NYC Board of Education, who has written widely on the fundamental flaws in the state tests.  Here, he shows how deep problems remain in their design and execution -- making their results, and the new teacher evaluation system and  teacher data reports based upon them, essentially worthless.  He goes on to urge parents to boycott the state exams this spring.  Please leave a comment about whether you would consider keeping your child out of school for this purpose!

New York State’s Testing Program (NYSTP) has relied on a series of deeply flawed exams given to 1.2 million students a year.  This conclusion is supported by comparing English Language Arts (ELA) and Math data from 2006 to 2011 with National Assessment of Educational Progress (NAEP) data, but not in the usual way.

Rather than ponder discrepancies in performance and growth on the national versus state exams, I analyzed the items—the building blocks of the NAEP and NYSTP that underlie their reported results.
NAEP samples fourth and eighth grade students in reading and math every two years.  Achievement and improvement trends are studied nationwide and broken down state-by-state.  The results spur biennial debate over two questions:
Why are results obtained on state-imposed exams far higher than proficiency as measured by NAEP?  Why do scores from state tests increase so much, while NAEP shows meager changes over time?  
By concentrating on results—counting how many students have passed state standards; or trying to gauge the achievement gap; or devising complicated value-added teacher evaluation models, school grading systems and other multi-variate formulas—attention has been diverted from the instruments themselves.
In 2009, the year statewide scores peaked, Regents Chancellor Merryl Tisch discredited NYSTP’s implausibly high achievement levels and low standards.  She pledged reform—“more rigorous testing” became the catch phrase.  She knew that New York’s yearly pursuit and celebratory announcements of escalating numbers belied a state of educational decline.
It was an admission of how insidious the results had been, not to mention the precarious judgments that rested on them. Unsustainable outcomes became a crisis.  But Albany refuses to address the core problem.
The NAEP and NYSTP exams contain multiple-choice and open-ended items.  The latter tap a higher order of knowledge.  They ask students to interpret reading material and provide a written response or to work out math problems and show how they solved them, not just select or guess a right answer.
Ergo, on well-developed tests students will likely get a higher percentage of correct answers on machine-scored multiple-choice questions.  In addition, the same students should do well, average or poorly on both types of items.   
NAEP meets the dual expectations of order and correlation between its two sets of items; the NYSTP exams, which are given in grades three through eight, do not.  Here are the contrasting pictures for the fourth grade math test. 
NAEP’s multiple-choice items yield averages that are substantially higher than its open-ended ones.  The distance between them is consistent over time—another way of saying that the averages run along parallel lines.  There is an obvious smoothness to the data.

Items on the NYSTP exams defy such rhyme and reason.  The percent correct on each set of items goes up one year and down the next in a choppy manner.  In 2008, performance on the teacher-scored open-ended items exceeded the level reached on the multiple-choice items. In 2011, when the tests were supposed to have gained rigor, the open-ended math questions were 26.2% easier than the NAEP’s.
                       
The reversals reveal exams made of items working at cross purposes, generating data that go north and south at the same time.  That’s the kind of compass the test publisher, CTB/McGraw-Hill, has sold to the State since 2006 to the tune of $48 million.
I found incongruities in all grades measured by NYSTP.  On the ELA, divergent outcomes on the two types of items are noteworthy for grades 5, 6 and 7 in 2010 and 2011.  The fifth grade items provide a jarring illustration, because they continue to function incoherently in the years of promised reform. Averages on the open-ended items increase (by 10.7%), as sharply as the multiple-choice averages fall (10.3%)—crossing over them last year.
It all goes unnoticed.  Press releases are written in terms of overall results without acknowledging or treating NYSTP’s separate parts.  This is odd since so much time and money go into administering and scoring the more challenging, higher-level open-ended items.
So, we’ve had a program that has made a mockery out of accountability, with the head of the Regents running interference for it.  Parents watch helplessly as their children’s schools become testing centers. And the quality of teachers is weighed on scales that are out of balance, as Governor Cuomo takes a bow for leveraging an evaluation system that depends on state test results to determine if a teacher is effective. 
If the test numbers aren’t good enough, there’s no way teachers can compensate by demonstrating other strengths needed to foster learning and growth.  Within days it is likely that newspapers will publish the names of teachers and the grades they’ve received based on their students’ test scores going back three years.  As shown, however, these results are derived from tests that fail to make sense.
The graphs are prima facie evidence that the vendor and Albany have delivered a defective product. High-stakes decisions about students, teachers and schools have depended on it. An independent investigation of NYSTP is imperative to determine what happened and, if warranted, to seek recovery of damages. 
It is also time for the victims—parents in defense of their children, and teachers in support of students, parents and their own self-interest—to band together and just say “No!” to this April’s six days of testing.
