There is so much wrong with this article by Eric Hanushek that I fear that anything less than a line-for-line rebuttal will be woefully inadequate as a response. Out of consideration for my readers, I will refrain from providing one, and will rather try to focus on the most important points. Hanushek, of course, is the Stanford economist whose lurch into the field of education has driven much of the recent misguided effort towards “Reform” in today’s educational system. His article does a good job of summarizing his most crucial arguments, so it’s worth some time examining.

The title of the piece is “Valuing Teachers” and a brilliantly disingenuous title it is. Rather than using the word as we might use it (placing a high value on teachers), he is using it as an economist might (assessing the value of teachers). He is measuring how much teachers are worth. According to Hanushek, better teachers result in higher incomes for their students later in life. To make his case, he uses a series of unscientific leaps of logic that will yield easily to a few moments of rationality.

He notes that “a student with achievement (as measured by test performance in high school) that is one standard deviation above average can later in life expect to take in 10 to 15 percent higher earnings per year.” I have no reason to doubt his numbers.

But Hanushek is making the classic blunder of confusing correlation with causation. Do higher test scores in school directly cause higher incomes? Or is it possible that they may have common contributing factors? What about factors that the student brings in, such as intelligence, stamina, and motivation? Is it possible that parental income can be a factor in both standardized testing scores and future income? Hanushek’s famous value-added study attempted to isolate these factors, but he seems content to ignore them when citing this achievement/income connection.

And, as Diana Senechal points out, “there is no evidence (as far as I know) that students in the highest percentiles in high school are those who made the greatest gains on their standardized tests over the years. In fact, I suspect that most of them did pretty well on those tests all along.”

Using future income as a measure of teacher quality is even more outrageous than using test scores. How much does a Stanford professor make compared to a Wall Street hedge fund manager? Is that a function of the quality of education they received? In the interest of full disclosure, I should mention that I make significantly less than LeBron James. Did he have better teachers?

Hanushek’s solution is to “contemplate asking 5 to 10 percent of teachers to find a job at which they are more effective so they can be replaced by teachers of average productivity.” (Note to my boss: if it should ever become necessary to fire me, I would request that you instead contemplate asking me to find a job at which I am more effective.)

Hanushek’s solution – fire the bad teachers – is very simple, but it requires several assumptions that I don’t think we should be so quick to grant.

Assumptions

1. Standardized tests accurately measure student achievement.
2. The teachers whose students don’t make progress on the tests are the bad teachers.
3. There is a line of average teachers at the door waiting to be hired.
4. No factors other than teacher quality are significant.

Peruse this list, and note that Hanushek’s plan falls apart if even one of these assumptions is false. In fact, they all are.

Assumption: Standardized tests accurately measure student achievement.

False. The tests that students are given are deeply flawed indeed. Many of the questions do not test what they purport to test, and test-taking itself has become it’s own skill set that schools ignore at their own peril. If we’re careful, we can use some the results to identify areas in need of improvement. But the tests on the whole are way too idiosyncratic to use the overall scores as a basis for high-stakes decision making.

Assumption: The teachers whose students don’t make progress on the tests are the bad teachers.

False. In an August 2010 paper for the Economic Policy Institute, a team of highly distinguished education researchers laid out the case against the use of student test scores to evaluate teachers. Bottom line: It doesn’t work. Test scores are simply an ineffective statistical measure for identifying bad teachers. If you don’t find twenty pages of research from a panel of experts compelling, then you can read about this well-respected hard-working teacher who got slammed by a statistical formula.

Assumption: There is a line of average teachers at the door waiting to be hired.

False. In fact, teacher recruitment and retention is becoming a serious problem. A McKinsey study, Closing the Talent Gap, describes the decline in the teaching profession’s ability to compete in the labor market.

However, I suspect there is a bit of condescension towards the profession of teaching when we assume we can just go out and hire average teachers. The implication is that the average person would make an average teacher, rather than acknowledging that teaching requires a particular set of qualities (e.g., diligence, patience, intelligence, and a calling to want to do it) for someone to even be an average teacher. To glibly say that we can just fire the bad teachers and hire average ones is unintentionally insulting.

Assumption: No factors other than teacher quality are significant.

False. Hanushek anticipates this rebuttal, and is kind enough to provide examples of other factors that are not significant:

The initiatives we have emphasized in policy discussions—class-size reduction, curriculum revamping, reorganization of school schedule, investment in technology—all fall far short of the impact that good teachers can have in the classroom. Moreover, many of these interventions can be very costly.

Costly? I thought we were discussing what is most effective. Aren’t we having a national education crisis? Hanushek has moved past his role as researcher and now is making policy judgements. Danny Westneat argues effectively against the idea that class size is irrelevant, so I don’t have to. Teachers already know the importance of class size, and I suspect that the Reformers do as well. Similarly, other initiatives we take to improve education, costly or no, are based on research and accumulation of best practices. Even if we let Hanushek fire all of the bad teachers, we would still want to implement successful education initiatives. Sorry.

Neither side is happy with our current educational system. But Reformers seem to offer nothing but slapdash solutions that keep expenses low but ignore the facts on the ground. It seems, then, we have a choice to make. Do we want to have a public education system in this country? Many do not, and would rather see the free market take over education. Charter schools seem to be a first step in that direction, and I think the Reformers who tout them have become, wittingly or unwittingly, somewhat of a stalking horse for the movement against public education. Diane Ravitch, in her eloquent response to Waiting for Superman, discusses why charter schools aren’t the panacea they’re often held up as. She also discusses the impact of poverty on student achievement, and the dangers of ignoring it in the national discussion. Paying teachers more? Keeping class size down? Addressing the needs of high-poverty schools? It all seems so… costly.

That’s what it’s going to take, though. If we want a high-quality public education system, we’re going to have to pay for it. These may be troubled economic times, but really it’s just a question of priorities. If we’re going to have public education at all, we need to increase, not decrease, funding for it. We need to increase it by a lot. Reformer “solutions” only distract from the real issue. They want us to look at charter schools, but if we look closely enough, we’ll see that the most successful charter schools are able to spend much more per student than the public schools who are expected to emulate them.

And so, we must choose between abolishing public education and funding it adequately. Abolishing it is not really a choice at all, and would lead to an even worse crisis than we have now. But, if we can adjust our priorities and give our students the schools they deserve, then, as Dan Quayle said, “We are going to have the best educated American people in the world.” (Should we be blaming his teachers?)

I recently saw a particularly poignant piece of graffito etched on a friend’s Facebook wall:

A public union employee, a tea party activist and a CEO are sitting at a table with a plate of a dozen cookies in the middle of it. The CEO takes 11 of the cookies, turns to the tea partier and says, “Watch out for that union guy. He wants a piece of your cookie.”

And while this might easily refer to any number of anti-labor sentiments, it seems most appropriate as a reaction to the current – inexplicable – War on Teachers that has been raging in the media lately.

If you haven’t seen last Thursday’s Daily Show, you really need to go watch it. In a brilliant piece at the top of the show, Jon Stewart demonstrates the hypocrisy of the right-wing talking heads when talking about teachers. Later, he interviews education truth-teller Diane Ravitch, who lays out the rest of the argument.

If you want to understand the conversations surrounding education reform, then – as Tom Tomorrow says in this week’s strip – that’s all you need to know.

I was talking to my graduate students about the literacy standards last night, and predictably got pulled off on a tangent about accountability. I found myself making a point that I’ve alluded to before, but it’s worth making explicit now.

Robert Benchley famously said “There are two kinds of people in the world: those who divide the world into two kinds of people, and those who don’t.” I will put myself in the former category when I say that, generally, there are two kinds of people who talk about standards and accountability.

The first believes that anything worth doing is worth doing well. In order to make sure we’re doing the best job we can, it’s important to measure our results, so we can identify areas for potential improvement and apply strategies for intervention where they will do the most good.

The second believes that taxpayer-funded education is one of the evils of socialism and must be eradicated. In order to make the necessary changes, evidence must be gathered that the public education system is a failure, so that arguments to turn education over to the free market will be more persuasive.

And my point was that, when you hear someone talking about standards and accountability, it’s important to know which of these two groups that person is in.

This makes three in a row from the same play, but Egypt’s in the news. I envision one possible outcome of the protests.

From Antony and Cleopatra:

Some innocents ’scape not the thunderbolt.
Melt Egypt into Nile! and kindly creatures
Turn all to serpents!

Shift around the letters, and it becomes:

Men end hell. Constant protesting stunts turn Hosni Mubarak to non-entity. People elect leaders directly.

Today I gave a workshop for Social Studies teachers on teaching our middle school history units. To illustrate the importance of learning history, I showed this clip.

This isn’t about ideology or politics. It’s frightening to me that a member of the United States House of Representatives, of either party, could be so dangerously unaware (deliberately or no) of the history of our nation. But the fact that she is considered a thought leader by so many on the other side gives me ideological concerns as well.

There’s a really good article on “The Economics of Global Warming” in Newsweek:

The most likely consequences of climate change will be severe impacts on food production in the developing world. We can worry about urban heat waves, polar bears, and forest fires, but the worst effects are almost certainly going to be on food production in the poor countries, where half or more of the population depends on growing its own food.

Estimates of lost world product due to climate change are moderate because the poor have so little to lose. More than a billion people, maybe 2 billion, are estimated to live on less than the equivalent of $2 per day. If a billion of those poorest people lost half their income, it would be an overwhelming tragedy, a true catastrophe, worse than all the earthquakes, floods, tsunamis, landslides, and fires of the past decade happening every year. But those billion people together would lose only $365 billion per year. That is less than 1 percent of world income! They have so little to begin with that what they can lose doesn’t amount to much of a statistic. But they can lose tragically.

It’s not a long article, so click here to read the whole thing.

The Antony and Cleopatra project is going well. Yesterday, I used the play to help the sixth-grade students make connections to present-day world events.

Antony and Cleopatra takes place in the first century B.C., a time when there was one global superpower in the world. By the time of the play’s opening scene, the Romans had scooped up most of the Hellenistic nations; only Egypt remained independent. However, both Romans and Egyptians were well aware that Egypt was living in Rome’s shadow. Philo has the opening speech of the play, and his racism and entitlement are readily on display:

Nay, but this dotage of our general’s
O’erflows the measure; those his goodly eyes,
That o’er the files and musters of the war
Have glow’d like plated Mars, now bend, now turn
The office and devotion of their view
Upon a tawny front; his captain’s heart,
Which in the scuffles of great fights hath burst
The buckles on his breast, reneges all temper,
And is become the bellows and the fan
To cool a gipsy’s lust. Look! where they come.
Take but good note, and you shall see in him
The triple pillar of the world transform’d
Into a strumpet’s fool; behold and see.

For a rank and file Roman soldier to speak of the Egyptian queen as “tawny” and a “strumpet” sets the tone for a world where there is an unequal balance of power.

Today, there is once again a single global superpower in the world, but that has only been true for the past twenty years. In fact, there have only been a handful of unchallenged superpowers in world history. (The Macedonians and the Mongols are the other two that come to mind. Others?) Therefore, this play offers a unique opportunity to explore power dynamics in our present world community.

How does it affect the world when there is one dominant superpower? What opportunities does that country have? What are its responsibilities in the world? How did Rome handle its power? How does the United States handle its power?

We had a fantastic conversation, and I think the students have a new lens for viewing both the play and world affairs.

There is only one posting to the message board, but I’m patient. And it looks like I am going to be working with an eighth-grade class on As You Like It asynchronously. I’ll be meeting with them the week after next, but most of our interactions will be online. Watch this space for updates!

UPDATE (That was fast): I’ve just added an Antony and Cleopatra category, so you can follow along with the project.

From Henry VIII:

The gentleman is learn’d, and a most rare speaker;
To nature none more bound; his training such,
That he may furnish and instruct great teachers,
And never seek for aid out of himself. Yet see,
When these so noble benefits shall prove
Not well disposed, the mind growing once corrupt,
They turn to vicious forms, ten times more ugly
Than ever they were fair.

The director of An Inconvenient Truth lent aid to ruthless enemies of government-funded education.

Davis Guggenheim’s Waiting for Superman should seek to learn the inherently right way: reform relentless poverty.

Instead, it prefers to foment barbed attacks on unions as anathemas. Why? Why?

Remember, the real superheroes teach in our schools.

More on Waiting for Superman here.

Davis Guggenheim’s new documentary about the need for reform in the American school system is one of the most important films of the year and everyone should go see it. Although I have a number of significant problems with the movie (which – rest assured – will be inventoried below), I think there are a lot of dark truths that Guggenheim brings to light, and even if we don’t all agree on what the solutions are, we can agree on what’s at stake in getting it right.

Waiting for “Superman” follows the journey of five students, and their individual quests to improve their educational opportunities. I’d say the movie gets about 75% of it right: the system is failing these students, and millions like them. But while it might make a good movie narrative to divide the issue into good guys (charter schools) and bad guys (teachers unions), the real issues surrounding education in this country are much more complicated than Guggenheim suggests.

I came out of the movie disappointed about many of the factual inaccuracies and glaring omissions that Guggenheim uses to make his case, but I found that these were well addressed by this piece in the Washington Post. Even better is this excellent article in The Nation, which digs much deeper into the issues surrounding the debate. I strongly recommend these two articles, as they cover a lot of ground that I consequently won’t need to cover.

I do believe that Guggenheim is sincere in his desire to reform education, and that’s important to say, because many participants in this discussion are not. Their goal is to end taxpayer-funded education entirely, and they tend to support measures that move the nation closer to this ultimate goal. The problem with this is that the free market will do an excellent job of educating some of our students, while a great number of children in this country will be starkly left behind. So I’m on my guard when I hear arguments about how charter schools have solved all of the problems faced by public education. But despite some of the darker connections behind Waiting for “Superman”, I do believe that the filmmaker is earnest and I can counter his points secure in the belief that we share the common goal of educating all of our students.

Not only does Guggenheim omit important details, but he often doesn’t even draw the correct conclusions from the evidence actually presented in the movie. What was most striking to me was how powerfully the film showed how the lack of economic opportunities for parents in these inner-city communities directly impacts the education of their children. That alone was worth the price of the surprisingly expensive ticket. But then, we’re told that “many experts” (who?) now believe that failing schools are responsible for failing communities, not the other way around.

Each of the five children depicted has a parent or guardian who is hell-bent on making sure the child has the best education possible. They enter their children into a lottery for the local high-performing charter schools. Presumably, all of the children in the lottery have similarly committed parents. That makes for a pretty good head start for the charter school. Public schools tend to have a more varied range of parent commitment. Also, did you notice how few students are accepted each year? What does that do for class size? And I have to mention, even though it’s well covered in the articles linked above, the large amounts of private funding that the high-performing charter schools depicted in the movie enjoy.

So yes, the charter schools in the film are doing very well, and that’s great news for the students who attend them. But if, as it is admitted in the movie, only one in five charter schools are showing results, that’s a dismal record indeed. And despite the emotionally manipulative scenes where each student’s “fate” was decided by random lottery, I felt myself more concerned for the students who were never in the lottery.

So perhaps the real lesson we can learn from the successful charter schools is that, if the school has a clear and progressive vision, then increased funding can actually make a difference in student achievement. And if we take a closer look at what Geoffrey Canada is really doing for the students in the Harlem Children’s Zone, we might realize that student achievement isn’t only impacted within the school building. He may have even created a microcosm of the society we would have if we could make the connection between our nation’s social fabric and the way our children are educated.

But “firing all the bad teachers” is a much more digestible solution.

And yes, there are bad teachers, and I agree that it should be easier to get rid of them. But in truth, this represents a very small part of the problem, and blaming teachers unions for the decline in educational quality is seriously misguided. Teachers unions have been and should be a partner in education reform, but they also have the task of protecting the rights of their members. Teachers have the same rights to collective bargaining as any other labor force in the country. To frame the issue as children vs. adults is a dangerous distraction, especially when our goal should be to attract the very best people to the profession, and retain them once they’re in. The movie makes the point that great schools start with great teachers. I agree! So let’s make teaching the most desirable profession in America. You can read more about teacher recruitment and retention issues in this Washington Post article. Because once we’ve fired all the bad teachers, who will we get to replace them?

By the way, nobody is actually waiting for Superman to come and save our children. It’s a classic rhetorical trick to frame the sides of the debate as the people who agree with the solutions provided and the people who would rather do nothing. But smart and passionate people are already implementing solutions within public education that resonate with the solutions presented by Guggenheim. Here in New York City, we’ve increased educational accountability enormously, and with the cooperation of the teachers union. Nationally, we’re moving towards Common Core Standards for student achievement. We’re not there yet, not by a longshot, but nobody in the system is complacent about that.

Still, despite all the movie gets wrong, it should be praised for shining a spotlight on issues that have been festering in the darkness. This movie has the potential to spark a national conversation about the problems in American education, and how we can best address them. If it does that, despite the film’s flaws, its ultimate effect will be a net positive. If it does that, it will be my very favorite of all of the Superman films.

UPDATE: An anagram review.

I am proud to announce that I have recently published a chapter in this book on teaching literature through technology. You can ignore the description; it seems to have been inadvertently switched with that of this book. Neither page describes my chapter, but you can read the abstract on the publisher’s page, or I could just tell you what it’s about.

Unlike this blog, the book chapter is actually about teaching Shakespeare! No riddles. No anagrams. No politics. (Well, maybe a little bit of politics.)

Here is the basic idea. I begin by citing experts who are skeptical of the ability of elementary school students to do Shakespeare. Specifically, I discuss the Dramatic Age Stages chart created by Richard Courtney.

Courtney describes “The Role Stage” as lasting from ages twelve to eighteen, at which point students are capable of a number of new skills that I would consider essential for understanding Shakespeare in a meaningful way. These skills include the ability to think abstractly, to understand causality, to interpret symbols, to articulate moral decisions, and to understand how a character relates to the rest of the play. So based on this chart, I would have to conclude that a student younger than twelve would not be ready to appreciate Shakespeare in these ways.

But Courtney bases his chart on the framework of developmental phases of Swiss psychologist Jean Piaget. These phases describe what a lone child can demonstrate under testing conditions. A more accurate and nuanced way of looking at development is provided in the work of Soviet psychologist Lev Vygotsky, who described a “Zone of Proximal Development” (ZPD), which is a range between what a child can demonstrate in isolation, and what the same child can do under more social conditions.

So I wondered if fifth-grade students (aged 10) would have some of the skills associated with “The Role Stage” somewhere in their ZPD. If so, a collaborative class project should provide enough scaffolding to develop those skills and allow ten-year-old students to understand and appreciate Shakespeare on that level.

So I developed and implemented a unit to teach Macbeth to a fifth-grade class in the South Bronx, using process-based dramatic activities, a stage production of the play performed for their school, and a web-based study guide to apply what they had learned. The idea was to use collaborative projects to get the kids to work together to make collective sense of the play. I then examined their written work for evidence that they had displayed the skills associated with “The Role Stage” in Courtney’s chart, and I was able to find a great deal of it.

I also create a three-dimensional rubric to assess the students’ work over the course of the unit. I say a three-dimensional rubric because I use the same eight categories in all three rubrics, but they develop over time to reflect the increased sophistication that I expect the students to demonstrate. I then compare the students’ performance-based rubric scores to their reading test scores to demonstrate that standardized testing paints only a very limited picture of what a student can achieve. (I did say that it had a little bit of politics.)

Anyway, that’s what my chapter was about. I just saved you $180! And I’m hoping to return to a regular blogging schedule soon, so more content is hopefully on the way.
