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.

You only really need to watch the first minute of this.

Yeah, she confused the arms race with the space race.

Also, President Obama wasn’t saying we needed to have a Sputnik moment like the USSR had; he was referring to America’s reaction to Sputnik, as a wake-up call.

And did I hear her say that President Obama wanted to “aspire” Americans?

Palin-Bachmann in 2012!

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.

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.

Feedback on my recent post about The Rules has led to a concern that my humor is too subtle and not everyone might get that it is a joke. As this regularly happens to me in real life, I thought it might be a good idea to sprinkle a few drops of water on my dusty-dry sense of humor, and clear up a few items on the blog that were always meant to be taken with a grain of salt.

ONE. The Rules were a satire that applies equally to members of both sides of the political spectrum, including me at times. You should definitely vote.

TWO. To the best of my knowledge, Rick Astley never performed in The Two Gentlemen of Verona. That was a Rickroll setup. Sorry. But there really is a “never give her o’er” speech.

THREE. The rap song “Mary, Mary” by Run DMC is not really about Queen Mary I of England. The song was actually written by Michael Nesmith of The Monkees. No, seriously.

FOUR. King Henry VIII never really used online file-sharing services. Someone really did search for that, though.

FIVE. President Bush did not really let the door hit him on the ass on his way out of the presidency. That’s just an expression.

SIX. Shakespeare did not really use PowerPoint. If he had, he would have probably created the best presentations ever, and today’s scholars would be debating whether or not he had really created them.

SEVEN. I was never really serious about the feud.

EIGHT. I am not really a mixer, a battery, or any of the other riddle answers. I am forty, though.

NINE. Waiting for Superman is not really my favorite of the Superman movies. I like the one with Richard Pryor better.

TEN. I don’t really think my readers need a list of examples of when I was joking. I just thought it would be funny.

It has recently come to my attention that not everyone is aware of The Rules. I am posting them here as a public service. Please familiarize yourself with them, as you will be held accountable for knowing them.

1. I have very strong opinions on a wide range of political issues. These opinions are the correct opinions. If you disagree with them, you are wrong.

2. I do not know why I was the one who was blessed with the correct combination of opinions, but I take my gift seriously, and am always willing to share them with those around me.

3. If you are on the other side of the political spectrum, you are the opposition. You are not on that side because you have a different set of core values and beliefs about how America can be improved. You only pretend to care about America to advance your sick and twisted agenda.

4. If you are on the same side as me, but closer to the center, you are the lapdog of the opposition.

5. If you are on the same side as me, but farther from the center, you are a fringe lunatic.

6. If you share my exact positions on all of the issues except for one, you are tragically misguided about that issue and are probably being misled by the mainstream media.

7. The mainstream media is definitely the lapdog of the opposition.

8. There are a great many issues where I disagree with Hitler. If you disagree with me on any of these issues, you are Hitler.

9. If, however, you compare me to Hitler, you are behaving inappropriately, and have automatically lost the argument.

10. Politicians are all corrupt liars. That’s why I don’t vote.

This Election Day, be like me. Don’t vote.
