Is Ravitch Really A Great Historian?

November 30, 2010

Given Diane Ravitch’s clear record of selectively and misleadingly citing the evidence on current education debates, we should wonder whether her much-lauded historical work contains similar distortions.  Someone so willing to pick and choose the evidence to serve her argument about current debates may well have the same proclivity to advance her preferred historical interpretation.

Detecting how Ravitch selectively reads the current evidence is relatively easy because the full scope of current research is knowable without too much effort.  But the full set of historical evidence from which an author chooses is less easily known to a lay reader.  How can anyone beyond the handful of scholars who have reviewed the original documents on a particular subject know whether Diane Ravitch or any other historian is correctly selecting and interpreting historical evidence?

The reality is that we can’t.  Most people tend to think that a historian is good because he or she writes well and makes an argument that is generally preferred by the reader.  It’s even unreliable to fully trust the opinion of other historians when assessing the quality of historical work.  Very few historians are intimately familiar with the same material, especially if the topic is highly specialized — like the history of American education.  And among those few historians their judgment on the quality of another person’s work may be colored by their professional interests in advancing similar interpretations or hindering opposing ones.

In short, it is very hard to know whether someone is really a great historian.  It is certainly harder to know the quality of historical work than empirical social science, especially when data sets are widely available and analyses can be replicated without too much effort.

Given that it is hard to know the quality of historical work and given Diane Ravitch’s distortion of the evidence in current debates, I’m inclined to doubt the quality of her earlier historical work.  Ravitch may have changed her views on some things but I highly doubt she has changed her standards of scholarship.  So, if her scholarship is lousy now, perhaps it was lousy before.

I’d be curious to hear examples that anyone may have of where Ravitch was sloppy or misleading in her historical work.  I bet they are out there even if they are harder to discover than her current sloppy and misleading work.


Ravitch is Wrong Site

November 29, 2010

Why serious people continue to care about what Diane Ravitch says is a mystery to me.  I know why rabid union-members and their allies keep lauding her and citing her as an authority — they like whoever repeats their talking points.  But why do journalists, like Valerie Strauss at the Washington Post, continue to act like Diane Ravitch matters?  Why does the Wall Street Journal give her valuable real estate on their editorial page to repeat untrue distortions, like:

To qualify for Race to the Top money, states and districts were expected to evaluate their teachers by using student test scores, even though research consistently warns of the flaws of this method. [Not true, as a Brookings blue ribbon panel just concluded that the research shows value added testing can be a helpful tool for teacher evaluations.] Similarly, the Obama administration is pressing states and districts to replace low-performing regular public schools with privately managed charter schools, even though research demonstrates that charters don’t, on average, get better academic results than regular public schools. [Again, not true.  Ravitch ignores the positive results of high quality random assignment charter evaluations in Boston and New York and instead focuses exclusively on a lower quality evaluation by Macke Raymond)]

Let’s say out loud what many people know but few have publicly said.  Diane Ravitch has undergone a personal, not an intellectual, transformation.  Because of that personal change she has acquired a new set of friends, including AFT boss Randi Weingarten.  Ravitch is basking in the admiration of these new friends for her remarks, but they are not well-thought-out or intellectually honest positions.

We devoted an entire week on JPGB to feature Stuart Buck’s documentation of how Ravitch is not an intellectually serious person anymore.  Now Whitney Tilson has organized an entire web site on his new blog that lists a host of critiques of the personally-transformed Diane Ravitch. It’s an extremely useful resource to which you can refer gullible journalists, like Strauss and the WSJ editors, whenever they start treating Ravitch as if she were a credible authority.


Education and Citizenship on the Left and Right

June 29, 2010

 

(Guest post by Greg Forster)

I’m bowled over by the new Claremont Review – Bill McClay’s cover story on the underlying cultural and educational sources of the nation’s current crisis is a real show-stopper. In the shorter items, Charles Murray has a great piece on the ups and downs of Ayn Rand, and my dissertation advisor Steven Smith has a fantastic (not that I’m biased) overview of the issues surrounding Heidegger’s Nazism.

In the education hopper, there’s Terry Moe’s Moore’s [oops!] review of E.D. Hirsch’s new book The Making of Americans. I haven’t seen the book yet; Moe Moore writes that Hirsch, always a man of the Left, makes the lefty case for curriculum reform centered on cultural literacy. To wit, schools paternalistically imposing upon children a homogeneous American culture strongly rooted in a matrix of moral values is the best way to help the poor rise, which is what lefties want.

Moe Moore also casually inserts that in this book Hirsch renews his flat-footed argument against school choice – that empowering parents with choice won’t improve schools because what schools need is better currucula. We’ve been around this merry-go-round with Hirsch before; his argument is like saying that empowering computer users to choose what computers they buy has no impact on the quality of computers; what makes computers better is that the computer companies invest in making them better. Of course, the reason computer companies work so hard to make their computers better, faster and cheaper every year is because they have to serve their customers in a highly competative market.

Moe Moore doesn’t draw the connection between Hirsch’s lefty argument for cultural literacy and his harebrained opposition to school choice, but the connection is there. It’s equally visible in Little Ramona, who – like Hirsch – has been wrongly considered a “conservative” for many years solely because she opposes multiculturalism and supports . . . well, the lefty argument for curriculum reform based on cultural literacy.

This matters because everybody’s all topsy-turvy about what is “progressive” or “conservative” in education, and it will take some effort to get our thinking straight.

Moe Moore picks up Hirsch’s statement that the movement for “progressive curricula,” i.e. the whole Dewey-inspired attack on traditional academic curricula, is really not a movement for a progressive curriculum but a movement against having any sort of “curriculum” properly so called. The point is not to change what’s in the curriculum but to have no substantive curriculum at all when it comes to inculcating a national character or a shared national culture. This is true, and it’s relevant to the question of why lefties who love cultural literacy hate school choice.

 

Since the late 1960s, the “progressive curriculm” (that is, the “anti-curricular”) movement has dominated the political left by making common cause with the teachers’ unions, who were not congenitally anti-curricular but whose interests were served by promoting the anti-curricular cause. As Moe Moore insightfully points out, the anti-curricular movement is really also an anti-teaching movement; it is therefore a perfect fit for the union agenda of more pay for less work. Thus, anyone who is “pro-curricular” is pigeonholed as being on the political right.

But that is a temporary phenomenon brought about by a unique confluence of political circumstances. In its historical orgins and in the logic of the position, the drive to use schools as engines of cultural homogeneity is a phenomenon of the authoritarian political left.

This goes all the way back to the roots of the system. It’s widely known that one of the major reasons America adopted the government monopoly school system in the first place was hysteria over the cultural foreignness of Catholics. However, there’s another tidbit worth knowing. As Charles Glenn documents in The Myth of the Common School, one of Horace Mann’s motivations for pushing the “common” school system was his vitriolic contempt for evangelical Protestant Christianity. The hicks in the rural Massachusetts countryside with their backward and barbaric adherence to traditional Calvinist theology – which had survived down through the centuries from the Puritan settlers – was repugnant to civilized and enlightened Boston-Brahmin Unitarians like himself.

Someone had to do something to rescue these culturally deprived children from their unenlightened parents! That’s why Mann’s schools had such a heavy emphasis on teaching the Bible – teaching it in a very particular way. Part of the school system’s purpose was cultural genocide against evangelicals, to use the power of the state to indoctrinate their children with unitarianism. And it worked beautifully; how many traditional Calvinists are left in Massachusetts?

[Update: It has been brought to my attention that the Presbyterian Church in America, a traditional Calvinist denomination, has lately been experiencing dramatic growth in New England. So perhaps I should have said “It worked beautifully; after a century of Mann’s schools, how many traditional Calvinists were left in Massachusetts?”]

What we have to get clear is that both the anti-Catholic and anti-evangelical hysteria – then as now – were on the political left.

The great crusade in the early 20th century to use the government monopoly school system to forcibly “assimilate” immigrants with “Americanism” was likewise a movement on the political left. On this subject, please do yourself the biggest favor you’ll do yourself all year and read (if you haven’t already) Jonah Goldberg’s Liberal Fascism. Fanatical patriotism was, until the convulsions of the 1960s, the special hallmark of the left, not the right.

The issues got scrambled after the 1960s by two factors. First and most important was the rise of an aggressive cultural ideology (what we now call “multiculturalism”) seeking to use the government school monopoly to impose its amoral and anti-American value system on the nation’s children. This movement was not only born on the left, but, as noted above, it formed a fruitful partnership with the unions who were also on the left. So naturally, the backlash formed on the right, and the identification of being “anti-multiculturalist” applied to conservatives. However, this was never really the same kind of animal as the left-wing authoritarian drive to use government schools to enlighten the benighted and make them into good Americans. Conservative anti-multiculturalism is negative and defensive in character; it’s not seeking to use government to impose a culture, but to stop the multiculturalists from doing so.

Second, as Goldberg documents, the authoritarianism of 20th century progressivism began to migrate over and infect the right; hence we get absurd specatcles such as a “conservative” president saying such things as “when people are hurting, government has to move.” And, similarly, some conservatives try to use the power of the state to impose right-wing cultural values. But this is really the result of conservatives having drunk from the polluted cultural water of left-wing authoritarianism.

Now let me be perfectly clear. Anxiety about whether young people are picking up 1) moral values and 2) cultural identity as Americans is of course widespread on both sides of the political isle. Believe me, I’m as worried as anyone about whether the nation is successfully passing on its civilization to its children, and whether today’s immigrants will assimilate and self-identify as Americans – not only for the sake of the nation, but for their own sake, since the chief victims of amoralism and multiculturalism are the people who believe in them.

The difference is not in being worried about this problem, but in how we want to solve it. Using the brute power of a government monopoly school system to paternalistically impose a homogenous culture has never been a conservative idea. Go back and look at the great conservative debates over this in the 1990s; whether you’re talking about William Bennett, James Q. Wilson or Charles Murray, you just never find conservative thought leaders talking that way. It’s the lefties like E.D. Hirsch and Little Ramona who dream that their cultural anxieties can be salved with the soothing balm of state power.

And really, it should be obvious why. If you’re the kind of person who thinks the brute force of state power can change culture, well then, you’re probably also a political lefty. If you’re the kind of person who thinks our culture will get along just fine if the state will just stop tinkering with it through social engineering, then you’re probably also a political righty.

It all comes down to how you concieve of the relationship between the government and the nation – which is to say, between power and culture. As Reagan famously asked, are we a nation that has a state, or a state that has a nation? To put the same question another way, does culture drive politics or does politics drive culture? Or, to put it even more bluntly, is the use of power shaped by the conscience of the nation, or do we use power to shape the conscience of the nation?

The conservative approach to schools and American culture is to use school choice to smash state power, thus depriving the multiculturalists of their only serious weapon. Get the state out of the way and let Americans worry about how to pass on American civilization to the next generation.

Oh, and here’s one other way you can tell that this is the conservative approach: the evidence shows it works.

Murray Misses the Mark

May 5, 2010

The New York Times features a piece by Charles Murray arguing that choice has failed to improve test scores.  In general, Murray doesn’t think schools can do much to improve test scores.  He says:

This is true whether the reform in question is vouchers, charter schools, increased school accountability, smaller class sizes, better pay for all teachers, bonuses for good teachers, firing of bad teachers — measured by changes in test scores, each has failed to live up to its hype.

It should come as no surprise. We’ve known since the landmark Coleman Report of 1966, which was based on a study of more than 570,000 American students, that the measurable differences in schools explain little about differences in test scores. The reason for the perpetual disappointment is simple: Schools control only a small part of what goes into test scores.

Cognitive ability, personality and motivation come mostly from home. What happens in the classroom can have some effect, but smart and motivated children will tend to learn to read and do math even with poor instruction, while not-so-smart or unmotivated children will often have trouble with those subjects despite excellent instruction. If test scores in reading and math are the measure, a good school just doesn’t have that much room to prove it is better than a lesser school.

Murray wants to be clear that he still favors choice, but not to improve test scores.  Instead, he favors choice because it satisfies the diversity of preferences about how schools teach and what they teach.  Standardized test scores impose a uniform concept of higher achievement on students, and so cannot capture the improved satisfaction of the diversity of tastes that choice can more efficiently satisfy.

There is a kernel of truth in Murray’s argument.  We should support school choice simply because it allows us the liberty of providing our children with the kind of education that we prefer.

But Murray is completely mistaken in asserting that choice cannot (and has not) produced improved outcomes on standardized measures.  The only research he references is the recently released, non-random assignment evaluation of the effect of Milwaukee’s voucher program on students receiving vouchers.  This ignores the 10 superior, random research designed studies summarized here.  Importantly, it also ignores the effects of expanding choice and competition on achievement in entire school systems.

Especially with regard to a large and mature voucher program, like the one in Milwaukee, the relevant thing to focus on is systemic effects, not participant effects.  Almost everyone in Milwaukee has access to expanded choice, so everyone is receiving the treatment — school choice.  The difference between voucher participants and non-participants is where they chose to go to school, not the difference between having access to choice or not. And if you look at the systemic effects study in Milwaukee it shows significant gains in student achievement as choice and competition are expanded.

It is irritating to have to repeat this discussion of the evidence each time Charles Murray, Sol Stern, or Diane Ravitch selectively cite (or ignore) the research literature and claim that choice has no effect.  It’s also puzzling why “conservative” activists feel the need to denounce choice and competition in order to promote their pet reform idea.

Murray may well be right that schools face serious constraints in improving student achievement, but you don’t have to trash the gains that have been realized to make that point.  (And I think the constraints are less severe than he suggests).

Stern may well be right that even schools in more competitive markets have to make good decisions with regard to curriculum and pedagogy to produce significant improvement.  But choice and competition facilitate schools making good decisions about curriculum and pedagogy by providing negative consequences for those who choose foolishly (as well as giving schools the freedom to try more effective instructional techniques).  And Ravitch may be right about … well, maybe she isn’t right about very much.

Are conservative activists so starved for attention that they are willing to feed the New York Time’s preferred strategy of promoting conservative in-fighting, just so they can get into the pages of the Grey Lady?

Ravitch is Wrong Week, Day #5

April 9, 2010

[Editor’s Note — This is the fifth and final installment in Stuart Buck’s critique of Diane Ravitch’s new book “The Death and Life of the Great American School System: How Testing and Choice Are Undermining Education.”  Below is a list (with hyperlinks) of all five posts for our Ravitch is Wrong Week. 

The only conclusion I can draw after reading Stuart’s critiques is that Diane Ravitch’s new book is not a serious piece of scholarship.  I do not know (and I do not care) why a normally serious education historian would write such a book.  The only thing that matters here is that much of what she has to say is wrong.  Unless and until she or someone on her behalf addresses the issues that Stuart has raised, I think we can dismiss this unserious book and the people who peddle it.]

  1. Ignoring or selectively citing scholarly literature;
  2. Misinterpreting the scholarly literature that she does cite;
  3. Caricaturing her opponents in terms of strawman arguments, rather than taking the best arguments head-on;
  4. Tendering logical fallacies; and
  5. Engaging in a double standard, such as holding a disfavored position to a high burden of proof while blithely accepting more problematic evidence that supports one’s own position (or not looking for evidence at all). ]

(Guest post by Stuart Buck)

DOUBLE STANDARDS:

The final problem endemic to Ravitch’s book is that she engages in a double standard — holding one side to a high burden of proof while putting forth positions or supposed facts that do not meet a high burden of proof (or that are completely unsubstantiated).

A typical pattern throughout Ravitch’s discussion of vouchers and charter schools is that she demands overwhelming proof of astonishing gains. For example, she sneers that vouchers did not produce “dramatic improvement for the neediest students or the public schools they left behind.” (p. 132).

But as for her own affirmative claims, Ravitch often proceeds with little or no empirical evidence, and many of her own policy prescriptions do not come with any proof of improvement, even of the undramatic sort.

For example, Ravitch claims that “most districts . . . relentlessly engage in test-prep activities.” (p. 159). Most? Relentlessly? Ravitch presents no evidence for these claims.

Ravitch claims that “regular public schools are at a huge disadvantage in competition with charter schools,” in part because “charters often get additional financial resources form their corporate sponsors.” (p. 136). Ravitch has no systematic evidence for any claim that charters are financially better off than public schools. Even in New York, which is home to many of the educational philanthropists that Ravitch seems to despise, charter spending in 2008-09 had a citywide average of $14,456 — including private giving. This compares to $16,678 for students in traditional public schools.

To be sure, these two figures aren’t directly comparable — the charter figure included all expenses for all students but without calculating the benefit of free space provided to certain charter schools, while the traditional public school figure came from a report that excluded large categories, such as special education or fringe benefits, but that did include the value of debt service to pay for facilities.

The point, in any event, is that Ravitch makes unsubstantiated and convenient claims about charter school financing without even attempting the difficult work of piecing through educational finance matters like these. Moreover, Ravitch’s claim is wrong as to the country as a whole. Charter schools nationwide receive an average of 61% of the funding given to traditional public schools, mostly because states usually refuse to let charter schools have funds for facilities.

Ravitch says on page 220, “If we are serious about narrowing and closing the achievement gap, then we will make sure that the schools attended by our neediest students have well-educated teachers, small classes, beautiful facilities, and a curriculum rich in the arts and sciences.” To be sure, having “well educated teachers” or “a curriculum rich in the arts and sciences” is common sense. But Ravitch has zero evidence that “beautiful facilities” would do anything about the achievement gap. Nor does she seem familiar with the Jepsen/Rivkin study finding that California’s initiative to lower class size ended up harming minority children (because their teachers find more job opportunities elsewhere and schools fill the gaps by hiring less qualified and more inexperienced teachers).

For another example, Ravitch says (p. 238) that “every state should establish inspection teams to evaluate the physical and educational condition of its schools.” Ravitch offers no evidence that such inspection teams make any difference whatsoever.

For another example, Ravitch says, “If we are willing to learn from top-performing nations, we should establish a substantive national curriculum that declares our intention to educate all children in the full range of liberal arts and sciences . . . .” (pp. 231-232). This sounds fine and well. But Ravitch has no evidence that pushing for a “national curriculum” would accomplish any of her putative goals, rather than being watered down and misdirected by all of the same interest groups that (a) distort the textbook adoption process (as Ravitch herself has documented) and (b) have prevented any such national curriculum from being established to date.

Another double standard lies in Ravitch’s treatment of the scholarly literature. For example, while Ravitch nitpicks to death any study with a pro-charter finding she dislikes (when she bothers to mention such studies at all), she credulously cites the Lubienskis’ study purporting to find that students in public schools do as well or better than those in private schools. (p. 140). She claims that this study “demonstrated the superiority of regular public schools.” It did no such thing: It was merely a cross-sectional snapshot of students in public and private schools, and the authors admitted that “we cannot and do not make causal claims from cross-sectional studies such as NAEP.”

Finally, Ravitch’s rosy depiction of public schools has no evidentiary support. E.g.: “The neighborhood school is the place where parents meet to share concerns about their children and the place where they learn the practice of democracy. . . . As we lose neighborhood public schools, we lose the one local institution where people congregate and mobilize to solve local problems . . . . For more than a century, they have been an essential element of our democratic institutions. We abandon them at our peril.” (pp. 220-21).

It’s hard to fathom how a historian could write such lofty rhetoric about the past century of public schools, while not even giving passing mention to the fact that during much of that century schools were officially segregated by race and steeped in anti-Catholic bigotry, and to this day are often unofficially segregated by class and race. (Ravitch seems to have forgotten all of the historical knowledge on display in this article.)

Of course, Ravitch’s words are literally correct: during the past century, public schools “have been an essential element” of society’s democratic attempt to solve the “local problem” of keeping out black people. If that’s not what Ravitch intends to endorse, then she shouldn’t write such unqualified paeans to schools of a century ago.

Moreover, what exactly does it mean to suggest that people “congregate and mobilize to solve local problems” at the school? That surely isn’t a routine function of the vast majority of public schools; when my kids were at the local public school, the only mobilization I saw was all the minivans accelerating after leaving the car line. In fact, the practice of grouping people into a single public school probably causes more “local problems” than it solves (consider the furious debates that arise over curricular issues alone — evolution, sex ed, phonics and math instruction, etc.).


Ravitch is Wrong Week, Day #4

April 8, 2010

[Editor’s Note — This is the fourth installment in Stuart Buck’s critique of Diane Ravitch’s new book “The Death and Life of the Great American School System: How Testing and Choice Are Undermining Education.”  Earlier this week he documented how Ravitch ignored or selectively cited scholarly literature, misinterpreted the research she did cite, and turned her opponents arguments into strawmen.  Today he focuses on how Ravitch’s book contains a series of logical fallacies.  Below is a guide to what you can expect (with hyperlinks as they become available) for our entire Ravitch is Wrong Week.

  1. Ignoring or selectively citing scholarly literature;
  2. Misinterpreting the scholarly literature that she does cite;
  3. Caricaturing her opponents in terms of strawman arguments, rather than taking the best arguments head-on;
  4. Tendering logical fallacies; and
  5. Engaging in a double standard, such as holding a disfavored position to a high burden of proof while blithely accepting more problematic evidence that supports one’s own position (or not looking for evidence at all). ]

(Guest post by Stuart Buck)

LOGICAL FALLACIES:

Non Sequitur.

Ravitch claims that her “support for NCLB remained strong until November 30, 2006 ,” which is when she attended an AEI conference at which various conservative scholars agreed that NCLB’s choice provisions were “not working.” (p. 100-01). This is because only a small percentage of parents asked to transfer to a different public school — although, as Ravitch herself concedes, this may have been because of the schools’ own failure to let parents know that transfer was an option, the lack of nearby public schools to which to transfer, and/or the pre-existence of generous public school choice programs.

In any event, if one thinks that school choice is generally a good thing — as Ravitch did at one time — it is completely incoherent and illogical to switch to the opposite position based on what Ravitch now claims was her rationale. Based on what Ravitch learned at the 2006 conference, she could logically have concluded that NCLB’s choice provisions were being thwarted by obstreperous school officials, or that NCLB’s choice provisions were not likely to work a revolution in public education. But she could not have logically concluded that choice was actually a bad idea that was undermining education. That belief about choice had to have arisen from other motivations, not the post hoc story that Ravitch puts forth.

The Law of Non-Contradiction

The most pervasive logical fallacy in Ravitch’s book is the self-contradiction. When it comes to curricular issues, Ravitch repeatedly throws out arguments that strongly imply, if not require, support for choice, vouchers, and charter schools — things that Ravitch otherwise tries to paint in a negative light.

For example, Ravitch praises Catholic schools for providing “a better civic education than public schools because of their old-fashioned commitment to American ideals.” As well, she laments the fact that “many Catholic schools have closed,” in part because of “competition from charter schools, which are not only free to families but also subsidized by public and foundation funds.” (p. 221).

So one would think that Ravitch would continue to support voucher programs wholeheartedly, as she so eloquently did in The New Republic once upon a time. Vouchers level the playing field by offering inner city kids the choice of Catholic or other private schools along with charter schools. But Ravitch doesn’t say anything about vouchers other than to credulously report a couple of studies that failed to find test score gains for voucher students while nitpicking over the recent DC voucher study that did find test score gains. Not only does this suspicion of vouchers contradict Ravitch’s claim to support Catholic schools, it more fundamentally contradicts Ravitch’s claim everywhere else that it’s not right to judge policies or schools based on test scores alone.

Another contradiction is in Ravitch’s claim that NCLB’s goal of 100% proficiency by 2014 is a “timetable for the demolition of public education in the United States ,” because “thousands of public schools [are] at risk of being privatized, turned into charters, or closed.” (p. 104). Notably, what little evidence she discusses directly disproves her dire predictions. On page 105, she notes that in a 2007-08 study, more than 3,500 schools were “in the planning or implementation stage of restructuring,” but that “very few schools chose to convert to a charter school or private management,” instead choosing the “ambiguous ‘any-other’ (i.e., ‘do something’) clause in the law.” In other words, thousands of schools are NOT at risk of being privatized or turned into charter schools; as Ravitch’s own meager evidence shows, those thousands of schools will almost all find a way around such a fate.

Another serious contradiction arises from Ravitch’s praise for the Core Knowledge curriculum. She notes that “students who have the benefit of this kind of sequential, knowledge-rich curriculum do very well on the standardized tests that they must take. They do well on tests because they have absorbed the background knowledge to comprehend what they read.” (p. 236). She similarly contends that “ironically, test prep is not always the best preparation for taking tests. Children expand their vocabulary and improve their reading skills when they learn history, science, and literature.” (p. 108).

But this point contradicts more than one of Ravitch’s other arguments. First, if students given a broad and rich curriculum in fact do better on reading and math tests, then it makes no sense to blame accountability (as Ravitch elsewhere does) for supposedly forcing schools to limit the curriculum to just reading and math. If Ravitch is right about Core Knowledge, she should spread the wonderful news that school leaders’ best bet is to adopt a broad and rich curriculum, rather than peddling the misinformation that testing inherently leads to a narrow test-prep curriculum.

Second, Ravitch ignores the fact that charter schools are nearly TWENTY times more like to adopt Core Knowledge as a curriculum than other public schools. (True, the percentage of charter schools that adopt Core Knowledge is still fairly small, but the percentage of public schools that adopt Core Knowledge is barely discernible at all.) Indeed, Ravitch herself previously documented in detail (“The Language Police”), so many entrenched interest groups play tug-of-war over the public schools that textbooks usually end up as the lowest common denominator. Given Ravitch’s previous work here, it’s quite odd for her, of all people, to fall back on the naïve hope that traditional public school systems will suddenly start adopting Core Knowledge or any similarly rigorous curriculum.

In any event, it is incoherent for Ravitch to disdain the one type of school that is most likely to adopt the curriculum she claims to favor. And again, it is an especially bizarre flight of illogic for Ravitch to disdain charter schools based on their test scores, which she elsewhere ridicules as an unfair way to judge the merit of a school.


Ravitch is Wrong Week, Day #3

April 7, 2010

[Editor’s Note — This is the third installment in Stuart Buck’s critique of Diane Ravitch’s new book “The Death and Life of the Great American School System: How Testing and Choice Are Undermining Education.” Over the last two days he documented how Ravitch ignored or selectively cited scholarly literature and then often misinterpreted the evidence she did cite. Today he focuses on how Ravitch frequently attacks straw man arguments rather than seriously addressing opposing views. Below is a guide to what you can expect (with hyperlinks as they become available) for our entire Ravitch is Wrong Week.

1)  Ignoring or selectively citing scholarly literature;
2)  Misinterpreting the scholarly literature that she does cite;

(Guest post by Stuart Buck)

STRAW MAN:

Ravitch’s book often caricatures her opponents’ arguments. For example, she writes (p. 229): “There are no grounds for the claim made in the past decade that accountability all by itself is a silver bullet, nor for the oft-asserted argument that choice by itself is a panacea.” She claims that choice and accountability were sold as “panaceas and miracle cures,” as an “elixir that promised a quick fix to intractable problems.” (p. 3).

Apart from one line that two authors (Chubb and Moe) wrote some 20 years ago, Ravitch does not identify anyone who has ever claimed that “choice by itself is a panacea.” Describing this claim as “oft-asserted” is simply untrue. Nor does Ravitch identify anyone who has ever claimed that “accountability all by itself is a silver bullet.” (I wonder if anyone has ever claimed that anything was a “silver bullet” — it’s a phrase that seems to be universally used only in denial.)

Another example: Ravitch writes that “reformers imagine that it is easy to create a successful school, but it is not.” (p. 137). She identifies no one who thinks that such a task is easy.

Another example: “Testing is not a substitute for curriculum and instruction.” (p. 111). Who ever said it was? And why can’t we have both?

Ravitch also claims that NCLB “assumed that higher test scores on standardized tests of basic skills are synonymous with good education.” (p. 111). Ravitch doesn’t cite anyone who has argued that test scores are literally “synonymous” with good education. The point of testing is that even though it’s not synonymous with good education, it can be a useful proxy that gives a quick determination of whether children have received any education at all. For example, if 8th graders can’t decipher a few written paragraphs and can’t solve straightforward math problems, then it’s a pretty good bet that they haven’t learned any higher skills either. And if schools couldn’t even teach simple math and reading skills — despite, according to Ravitch, focusing like a laser beam on those skills for several years now — can those schools really be trusted to teach the broad and rich curriculum that Ravitch wants?

Ravitch claims that “unionization per se does not cause high student achievement, nor does it cause low achievement.” (p. 175). Opponents of teacher unions do not argue that unionization “per se” causes some absolute value of low or high achievement, but that unions — by protecting the jobs of bad teachers or by opposing the high academic standards that Ravitch herself favors– can depress academic achievement from what it otherwise would have been. What’s worse, Ravitch supports her claim by noting that “ Massachusetts , the state with the highest academic performance, has long had strong teacher unions.” But as Ravitch well knows, the very academic improvement that she admires in Massachusetts was won only over tenacious union opposition. As Robert Costrell says, even if unions failed to prevent academic achievement in Massachusetts , “it was certainly not for lack of trying.” (By the way, we have here yet another example of Ravitch ignoring contrary scholarly literature even when it was specifically brought to her attention nearly a year ago.)


Ravitch is Wrong Week, Day #2

April 6, 2010

[Editor’s Note — This is the second installment in Stuart Buck’s critique of Diane Ravitch’s new book “The Death and Life of the Great American School System: How Testing and Choice Are Undermining Education.”  Yesterday he documented how Ravitch ignored or selectively cited scholarly literature.  Today he focuses on how she misinterprets the research she does cite.  Below is a guide to what you can expect (with hyperlinks as they become available) for our entire Ravitch is Wrong Week.

  1. Ignoring or selectively citing scholarly literature;
  2. Misinterpreting the scholarly literature that she does cite;
  3. Caricaturing her opponents in terms of strawman arguments, rather than taking the best arguments head-on;
  4. Tendering logical fallacies; and
  5. Engaging in a double standard, such as holding a disfavored position to a high burden of proof while blithely accepting more problematic evidence that supports one’s own position (or not looking for evidence at all). ]

MISREADING OR MISDESCRIBING SCHOLARLY LITERATURE

Another source of bias is that Ravitch’s book is often inaccurate or selective in how it interprets particular scholarly studies. What follows are several examples:

1. Ravitch cites a paper by Cecilia Rouse and Lisa Barrow that supposedly reviewed “all the existing studies of vouchers in Milwaukee, Cleveland, and the District of Columbia.” (p. 129). Ravitch’s description is untrue: Rouse/Barrow did not even purport to review “all the existing studies,” instead stating that they would “present a summary of selected findings from publicly-funded voucher programs with formal evaluations.” Sure enough, Rouse and Barrow left out several studies, as this site has previously documented.

2. In describing an evaluation of the Milwaukee voucher program, Ravitch writes, “In the first year of the study, they found that students in the regular public schools and those in the voucher schools had similar scores.” (p. 129). It seems that Ravitch must have read only the newspaper account that she cited, which was so misleading that the study’s co-authors were forced to write a lengthy letter to the Milwaukee newspaper refuting the claim that Ravitch is now repeating:

To start the five-year study, we had to place the voucher and MPS students in our sample on an equal footing, academically. The test scores of the two groups were closely matched to each other, by design.
We have essentially placed the two groups at a common starting point. It would be absurd to determine the winner of a race based on the positions of the competitors at the starting line. Similarly, no one should draw conclusions about the performance of the voucher program based on information from the initial baseline year of a longitudinal study.

3. Ravitch cites a 2007 Center for Education Policy study as having found that “62 percent [of school districts] had increased the time devoted to reading and mathematics in elementary schools, while 44 percent reported that they had reduced the amount of time spent on science, social studies, and the arts.” (p. 108).

What the CEP report actually found was that 44 percent of districts claimed to have cut “time from one or more other subjects or activities (social studies, science, art and music, physical education, lunch and/or recess) . . . the decreases reported by these districts were relatively large, adding up to a total of 145 minutes per week across all of these subjects, on average, or nearly 30 minutes per day..”

It’s a bit different, isn’t it, to know that out of a 6-7 hour school day, these schools were actually reallocating merely 30 minutes per day away from 4 academic subjects plus physical ed, lunch, and recess? And why is this necessarily so bad anyway? If these schools were failing at the minimal task of teaching kids how to read and do basic math, then why shouldn’t they spend just a little more time on those subjects and a little less time on recess or even “social studies”?

[UPDATE: What I have in mind here are kids who can’t decode but are wasting time in other classes making posterboards and the like.  If the kids actually do know how to decode, then I agree that a substantive curriculum like Core Knowledge would be much better than more hours of “reading” instruction . . . but then again, I’d bet that the schools reallocating time like that aren’t competent enough to have such a curriculum in the first place.]

4. Ravitch discusses Florida’s practice of assigning letter grades (A to F) to schools. She says that she “abhor[s]” the practice, and notes with seeming disapproval that the state “sanctioned F-rated schools by giving vouchers to their students, who could use them to attend a private or better-performing public school.” (p. 164). Notably, she cites the Rouse/Hannaway/Goldhaber/Figlio paper on the Florida voucher program, but without mentioning the crucial fact that Rouse et al. found that “student achievement significantly increased in elementary schools that received an “F” grade by between 6 to 14 percent of a standard deviation in math and between 6 to 10 percent of a standard deviation in reading in the first year. Three years later the impacts persist.”

This finding directly contradicts Ravitch’s arguments against accountability systems, not to mention her skewed and inaccurate claim that vouchers fail to pressure public school systems to improve (pp. 129-132).


Ravitch is Wrong Week, Day #1

April 5, 2010

Diane Ravitch’s new book “The Death and Life of the Great American School System: How Testing and Choice Are Undermining Education” has been burning up the charts. Ravitch has been ubiquitous, writing op-eds in support of her book, doing lectures and interviews all over the place, and being reviewed in all sorts of high-profile venues.

As an overall matter, the book says little, if anything, that is actually new on the subjects of testing and choice. What Ravitch is really selling with this book is the story of her personal and ideological conversion. Not so long ago, she was writing articles like “In Defense of Testing,” or “The Right Thing: Why Liberals Should Be Pro-Choice,” a lengthy article in The New Republic that remains one of the most passionate and eloquent defenses of school choice and vouchers in particular. Now she seems to be a diehard opponent of these things. But she’s not saying anything that other diehard opponents haven’t already said countless times.

The book does score a few points in critiquing the charter school movement (e.g., charter schools have an unfair advantage in competing with Catholic schools in the inner cities, and charter test results haven’t been as promising as might have been expected), or in critiquing testing and accountability (e.g., states have been watering down their standards, as shown by wide discrepancies between NAEP and state tests).

But these few good points are outweighed by the bad arguments and leaps of illogic that permeate much of the book. The book’s faults fall into five general categories, each of which will be the subject of a blog post this week:

  1. Ignoring or selectively citing scholarly literature;
  2. Misinterpreting the scholarly literature that she does cite;
  3. Caricaturing her opponents in terms of strawman arguments, rather than taking the best arguments head-on;
  4. Tendering logical fallacies; and
  5. Engaging in a double standard, such as holding a disfavored position to a high burden of proof while blithely accepting more problematic evidence that supports one’s own position (or not looking for evidence at all).

IGNORING SCHOLARLY LITERATURE

An endemic problem with Ravitch’s book is the tendency to cite only one or two studies on a disputed empirical question as if that settled the matter, while ignoring other (often better) studies that undermine or refute her claims.

For example, Ravitch claims that vouchers don’t pressure traditional public school systems to improve (pp. 129-32), even though the scholarly consensus is precisely the opposite. Ravitch also highlights a couple of studies that failed to find achievement gains from vouchers, but ignores the fact that “9 of the 10 [random assignment studies] show significant, positive effects for at least some subgroups of students.“

One of the most egregious examples arises from Ravitch’s repetitive claim that charter schools tap into the most “motivated” students. This claim appears practically every time Ravitch mentions charter schools. See, e.g., p. 145 (“charter schools are havens for the motivated”); p. 156 (“A lottery for admission tends to eliminate unmotivated students”); p. 212 (“two-tiered system in urban districts, with charter schools for motivated students and public schools for all those left behind”); p. 220 (“Charter schools in urban centers will enroll the motivated children of the poor, while the regular public schools will become schools of last resort for those who never applied or were rejected.”); p. 227 (“Our schools cannot improve if charter schools siphon away the most motivated students”).

Notably, Ravitch doesn’t highlight any actual evidence for this claim. She treats it as definitionally true (“by definition, only the most motivated families apply for a slot,” p. 135). But that is wrong: The only thing that could be true by definition here is that parents who sign up their children for charter schools are the most motivated to sign up their children for charter schools, which is a trivial observation (and one that probably isn’t true anyway: some motivated parents might easily fail to hear about a charter school opportunity, while other parents might sign up on a whim).

But that’s not the “motivation” that Ravitch means. What Ravitch tries to imply — and what she lacks any evidence for — is that charter schools all over the country are over-enrolling those students who are the most motivated to succeed academically. That’s the only thing that could possibly lead to an unfair charter school advantage. To be sure, there are undoubtedly some charter students who are the most academically well-prepared and who are leaving the public school to seek a greener pasture elsewhere. But, Ravitch has zero evidence that these children are in the majority.

Nor would such a contention be consistent with the actual evidence, which Ravitch doesn’t bother to investigate (having presumed to settle the motivation issue “by definition”). In fact, a recent paper by Zimmer et al. analyzed data “from states that encompass about 45 percent of all charter schools in the nation.” They found: “Students transferring to charter schools had prior achievement levels that were generally similar to or lower than those of their [traditional public school] peers. And transfers had surprisingly little effect on racial distributions across the sites.” Similarly, Booker, Zimmer, and Buddin (2005) found that in California and Texas — both huge charter states — students who transferred to charter schools had lower test scores than their peers at public schools.

Given this evidence, it is more plausible to suspect that many charter school entrants have been struggling to get by in the public school, and they (or their parents) are “motivated” only in the sense that they’re trying to find something that might work. It’s hard to see how that sort of motivation would create an unfair advantage on the part of charter schools, as Ravitch wants the reader to believe.

There are numerous other examples of Ravitch ignoring scholarly literature that she finds inconvenient:

1. Ravitch focuses on a few studies about whether charter schools increase test scores. Leaving aside the fact that this is completely incoherent (given that Ravitch’s whole point elsewhere is that test scores shouldn’t be used to tell us the worth of a school), Ravitch ignores the recent study showing that charter schools increased the likelihood that a student will graduate and go to college. These are worthy goals.

2. Ravitch cites Walt Haney’s study asserting that “dramatic gains in Texas on its state tests” were a myth. (p. 96). But she ignores the Toenjes/Dworkin article contending that Haney’s article was biased and unreliable.

3. Ravitch attacks NCLB for failing to bring about its intended goal: improved test scores. For this argument, she relies on snapshots of NAEP scores during the 2000s. (pp. 109-10). But one looks in vain for Ravitch to cite Hanushek and Raymond’s paper noting that it is “not possible to investigate the impact of NCLB directly” — that is, it is not possible to do exactly what Ravitch purported to do. This is because “the majority of states had already instituted some sort of accountability system by the time the federal law took effect . . . 39 states did so by 2000.”

Hanushek and Raymond went on to find that “the introduction of accountability systems into a state tends to lead to larger achievement growth than would have occurred without accountability. The analysis, however, indicates that just reporting results has minimal impact on student performance and that the force of accountability comes from attaching consequences such as monetary awards or takeover threats to school performance. This finding supports the contested provisions of NCLB that impose sanctions on failing schools.” This finding is similar to Carnoy and Loeb 2002 (another paper left uncited by Ravitch), who found that “students in high-accountability states averaged significantly greater gains on the NAEP 8th-grade math test than students in states with little or no state measures to improve student performance.”


Little Ramona Delivers the Fail

March 9, 2010

(Guest post by Greg Forster)

My response to the article in today’s Journal by Little Ramona is mostly the same as Whitney Tilson’s response to her book. From his e-mail blast today:

So far I’m hugely unimpressed.  She does a nice job of capturing the failures of the existing system and takes delight in poking holes at reform efforts over the past decade (while playing fast and loose with the facts and/or only presenting one side of the story), yet there is a shocking, gaping void when it comes to any thoughtful ideas for alternatives.

In other words, her attempt to say anything that is either new or interesting has failed.
