Bruce Baker chides state policymakers for claiming that they are relying on MET, the Gates’ teacher evaluation program.

In his previous post, Baker delves into the ways that state officials are misusing value-added measurement and student growth percentiles. I asked Bruce if he would clarify the difference and he responded as follows (go to the link to see the video):

The key difference is explained in the previous post – which I think needs more attention:

With value added modeling, which does attempt to parse statistically the relationship between a student being assigned to teacher X and that students achievement growth, controlling for various characteristics of the student and the student’s peer group, there still exists a substantial possibility of random-error based mis-classification of the teacher or remaining bias in the teacher’s classification (something we didn’t catch in the model affected that teacher’s estimate). And there’s little way of knowing what’s what.

With student growth percentiles, there is no attempt to parse statistically the relationship between a student being assigned a particular teacher and the teacher’s supposed responsibility for that student’s change among her peers in test score percentile rank.

Quick summary is that value added models attempt, I would argue unsuccessfully, to parse the influence of the teacher on student test score growth, whereas growth percentile models make no effort to isolate teacher effect. It’s entirely about relative reshuffling of students, aggregated to the teacher level.

As I say in the video:

One approach tries (VAM) and the other one doesn’t (SGP). One doesn’t work (VAM) and the other is completely wrong for the purpose to begin with(SGP).

You have no doubt heard the story of Parent Revolution. That is the group that wants to “empower” parents to seize control of their schools so they can turn it overto a charter operator.

The founder of Parent Revolution previously worked for Green Dot charters. Then he got funded by Walton, Gates, and Broad to start Parent Revolution.

A typical corporate reform sham since there are no parents involved, unless you count Ben Austin, the executive director.

An investigative reporter just did a story about Parent Revolution and was able to determine that the big funding comes from Walton, which has put more than $6 million into the endeavor. Walton is the most conservative of the big foundations. And clever too.

Walton has an agenda, and it can be summed up in one word: privatization.

By now, we have all read the encomia heaped on KIPP, and we know that KIPP presumably has what Mayor Rahm Emanuel once referred to as the “secret sauce.” That is the extra ingredient that
magically turns ordinary kids into scholars bound for Harvard.

Gary Rubinstein, ex-TFA, went to visit a KIPP school. He didn’t see the magic. He saw young teachers struggling to control their classes.

Read it to see what goes on, and be sure to read the comments.

A new report from CReATE, an organization of education researchers in Chicago, says that the Chicago Public Schools dramatically underestimated the number of children who will be affected by the mass elimination of public schools in that city.

No one will ever accuse CPS of undue compassion, concern, or attention to the city’s neediest children. As their legacy, they will be remembered for their cold and ruthless indifference to the children who are most at risk.

Please read the CReATE report:

“CReATE Researchers on Impact of Proposed School Closing”

CReATE researchers Josh Radinsky and Federico Waitoller (University of Illinois-Chicago) have prepared a report that details the impacts of the proposed school closings in Chicago in terms of student relocation and faculty dismissal. These researchers find that CPS statements on this matter greatly underestimate the scale of the impact. One of the stunning facts this report reveals is that the number of African American elementary students to be impacted by these actions (34,946, elementary only, not counting the 8 high schools) represents over 27% of all African American children between the ages of 5 and 14 living in the City of Chicago.

The New York Times recently reported on the introduction of software that is able to grade student essays and give instant feedback. It is currently being used in a number of universities; many others are likely to follow suit.

The student submits an essay and instantly receives a graded response from a computer. The student can then revise in hopes of improving the grade.

The software inevitably will be adopted for use in schools as well as colleges and universities.

Actually the Educational Testing Service already has an essay grader that can grade 16,000 essays in 20 seconds. Michael Winerip wrote about this in another article in the New York Times, back when he had a regular education column.

In both articles, the chief critics of machine grading of essays is Lew Perelman of MIT, who teaches writing. He says that it is easy to game the system, to prep for it; he also says that the system cannot identify good writing. It does not like short sentences or short paragraphs. Worse, as he says about the ETS system, it cannot tell truth from falsehood:

“He tells students not to waste time worrying about whether their facts are accurate, since pretty much any fact will do as long as it is incorporated into a well-structured sentence. “E-Rater doesn’t care if you say the War of 1812 started in 1945,” he said.”

Brave New World, indeed.

Jonathan Pelto reports that the Connecticut House approved the nomination of a charter school executive to the State Board of Education.

According to his account, Governor Dannell Malloy promised that if she was confirmed, the next two appointments to the state board would be individuals who support public schools, where the vast majority of the state’s students are enrolled.

 

Jersey Jazzman is really steamed about NY State Commissioner John King.

Is it because he wants to share the personal, confidential data of ll the state’s public school students with a marketing consortium?

Is it because he is pushing the Common Core standards without first determining how they will affect real children?

Is it because he came from the charter sector, from a no-excuses school with military discipline?

Or it because his own kids attend a lovely Montessori school that promotes respect, loving kindness, independence, critical thinking, and other things that most parents want for their children?

Jay Mathews wrote that he no longer believes that teachers should be evaluated by test scores.

However, he went on to say that teachers should be judged by their principal, and that principal should have the absolute power to hire, pay, judge, and fire teachers at will. If we don’t like the principals, we should fire them and get others.

Here is the answer to Jay by Carol Burris, who was just named principal of the year by her colleagues in New York State:


The better answer is to put in place systems of supervision and evaluation like [Montgomery County’s] PAR [Peer Assistance and Review]. This obsession that we can ‘fear and fire’ our way to excellence, is nonsense. ‘Give them (principals) the power to hire, compensate and fire staff members as they see fit”. This principal says….bad idea. As is doing the same for principals. That is still putting evaluation by tests scores in a primary place. It will also make schools more political than they already are and create more “Atlantas”.

As readers of this blog know, there is a healthy discussion about what to call those who now claim to be “reformers.”

In this post, Leo Casey of the Shanker Institute discusses whether there is any such thing as “corporate reform.” Larry Cuban says there is not.

Let’s review what I often refer to as “corporate reform.”

I call it “corporate reform” because the reformers want to use crude metrics to judge teachers and schools. They think that data are better measures of quality than professional judgment. On the basis of standardized test scores, they are happy to label schools as “failing” if their scores are low and happier still to close them for the same reason. The test scores are like a profit and loss statement. The corporate reformers speak about having a “portfolio” of schools, sort of like a stock portfolio, where you keep the winners and get rid of the losers.

When they manage school districts, they invent fancy corporate-sounding titles like “chief talent officer,” “chief knowledge officer,” “chief portfolio officer,” etc. to take the place of school titles like “superintendent” and “deputy superintendent.”

The face of the “reform” movement is Michelle Rhee. She works closely with such figures as Joel Klein and Jeb Bush, John Kasich in Ohio, Mitch Daniels (now ex-governor) in Indiana.

These so-called reformers advocate for private management of schools by charter organizations, whether nonprofit or for-profit.

Some (Jeb Bush, Michelle Rhee, Bobby Jindal, Scott Walker, Tony Bennett) but not all of them advocate for vouchers .

They say that our public school system is “broken,” “failing,” and “obsolete.” So to them, it makes perfect sense to replace them with private management.

They advocate for high-stakes testing.

They want teachers and principals to be evaluated to a significant degree by the test scores of students.

They applaud the closing of schools (cf. Rahm Emanuel).

They disdain local school boards, which might slow down the process of privatization of public funds.

They want to remove any due process rights from teachers, so they can be hired and fired at will.

They seek to cut teachers’ pensions and benefits.

They think that “great” teachers need only a few weeks of training. They like to put non-educators in charge of school districts and schools. After all, if someone can market toothpaste, they can also market automobiles or schools.

If you think there is no movement to undermine public education and the education profession, I don’t agree.

If someone has a better name than “corporate reform,” I am all ears.

Mercedes Schneider, who holds a Ph.D. In statistics, analyzes Patrick Wolf’s evaluation of the voucher program in Milwaukee. Wolf acknowledges that the voucher program may not have raised student achievement but claims that it increased graduation rates. This “success” was qualified by a high attrition rate. In the initial study, he said that the attrition rate was 75%, but subsequently revised it to 56%.

Dr. Schneider took a closer look at the study. In this post, she demystifies the technical jargon for non-specialists and clearly explains why the methods employed by Wolf and his associates do not offer much reassurance about the value of vouchers.
