Teachers are nervous about Michelle Rhee's suggestions because they're afraid other people in power will act like Michelle Rhee

The debate over job security for teachers is often employs an analog of the "If you're not hiding something..." argument in national security. Just as those who are guilty of nothing are supposed to have no reason to object to searches and wiretaps, teachers who are effective and conscientious have nothing to fear from the elimination of tenure and LIFO.

The argument works on two levels: it has a convincing though overly simplistic logic and it casts aspersions on the competence and character of those who object to it.

Of course, it collapses completely if those with the power to hire and fire ignore educators' accomplishments, make arbitrary and opaque decisions, play politics, let small factions gain undue influence over the process.

Rhee Dismisses Principal of School That Her Children Attend

By Bill Turque
Washington Post Staff Writer
Friday, May 9, 2008

Oyster-Adams Principal Marta Guzman can recall the ripple of anxiety that ran through some faculty members last summer when they learned that the new D.C. schools chancellor, Michelle A. Rhee, had chosen the bilingual school for her two daughters, a kindergartner and a third-grader.

But Guzman, an educator with more than 30 years' experience, said she wasn't concerned. The dual-immersion program, where native English and Spanish-speaking children learn side by side, has long made the Cleveland Park school among the city's most coveted, with high test scores and a national Blue Ribbon for academic achievement. Every year, parents from outside its attendance boundaries vie through a lottery for a handful of spaces to enroll their children.

"I thought it was a good thing," she said of the Rhee children's enrollment.

This week, Rhee fired her.

Guzman received a form letter from Rhee informing her that she was out of a job effective June 30, one of at least two dozen principals whose contracts for the 2008-09 school year were not renewed. Guzman said she was given no reason for her dismissal, either in the letter from Rhee or at a Monday meeting with Assistant Superintendent Francisco Millet.

...

Guzman's departure has stunned many Oyster-Adams parents who wonder why, in a city filled with under-performing public schools, Rhee would sack a principal who has presided for the past five years over one of its few success stories. The move has also heightened ethnic and class tensions within the school's diverse community. Eduardo Barada, co-chairman of the Oyster-Adams Community Council, the school's PTA, said Guzman was toppled by a cadre of dissatisfied and largely affluent Anglo parents with the ear of a woman who was both a fellow parent and the chancellor.

"I believe there are some parents who want to control and dominate," he said. "They want to silence the Latinos there."

Claire Taylor, council co-chairwoman, said she "absolutely respects Eduardo's position" but doesn't agree with it. "From what I've seen of Michelle Rhee, she is an exceedingly fair person who wants what's in the best interests of the students," she said.

Taylor added that ethnic and class divisions are the norm at Oyster-Adams. "A leaf falls and there are issues," she said.

Taylor was one of a group of Oyster-Adams parents, both white and Latino, who dined with Rhee in November and aired complaints about Guzman. Among the issues raised with Rhee, who took notes, according to another attendee, were Guzman's alleged lack of organization, reluctance to delegate and sometimes-brusque style.

Asked to discuss the dinner, which was at the home of another parent, Taylor said she was "not going to get into intra-school politics."

...

The first sign that her job was in jeopardy, Guzman said, came last month, when Millet convened a meeting of Oyster-Adams teachers to discuss her leadership. Guzman, who was not invited to the meeting, said she learned from a teacher that Millet began the meeting by announcing that a national search was underway for her replacement.

She quickly asked for a meeting with Rhee, who told her about the dinner meeting. Rhee said parents were frustrated by Guzman's lack of organization and "not comfortable with her" on a personal level.
...

Maureen Diner, who has a fourth-grader at the school, said Rhee's silence is not seemly for a chancellor who came into office a year ago promising reform.

"Anybody asked not to return deserves a process, at the very least a community meeting," Diner said. As for Rhee, "she talked about creating a culture of accountability. At the same time, she needs to be accountable for her own actions."

I wish I could say I was shocked to read this, but I can't. I can't tell you that this sort of politics is unusual. I can't even claim that this is my first encounter with a dinner party putsch.

At the risk of putting too fine a point on what is already a damned sharp spike, a group of parents who invite the chancellor of a major metropolitan school district over for dinner will not, as a rule, be poor, simple, honest workin' folk. They will tend to be wealthy, influential and grossly unrepresentative. To accept their invitation at all showed exceptionally poor judgement. To fire one of the district's most effective administrators based on their influence showed none whatsoever.

Of course, under the current system, teachers have protections that principals don't. They can give poor grades for poor work, keep the wooden and the clumsy in the chorus and the second string respectively, write honest evaluations. They can, and often will, be harassed for doing their jobs but they aren't in danger of losing them.

At least for now.

NYT Paywall -- still getting the feeling they haven't thought this through

As Felix Salmon observes "Here’s the difference, Arthur: stealing a paper on 6th Ave is illegal."

In coal's defense, it is a wonderful source of mercury

From Michael Froomkin (via DeLong):

The little tiny box is “nuclear.”

I knew this, and the chart still is effective. And my kids were at first very skeptical last week when I tried to tell them that so far coal had killed far more people than nuclear power. (Of course the very worst case scenario for a nuclear plant is much worse than the very worst case scenario for any coal-fired plant; but the very worst case scenario for coal plants aggregated is…global warming.)

Introducing the headless clowns analogy

(Believe it or not, I really am going somewhere with this.)

From Friends, season 2:

Chandler: Please tell me you know which one is our baby.

Joey: Well, well that one has ducks on his t-shirt, and this one has clowns. And Ben was definitely wearing ducks.

Chandler: Ok.

Joey: Or clowns. Oh, oh wait. That one's definitely Ben. Remember, he had that cute little mole by his mouth.

Chandler: Yeah?

Joey: Yeah.

Chandler: Hey, Ben, remember us? Ok, the mole came off.

Joey: Ahh!

Chandler: What're we gonna do? What're we gonna do?

Joey: Uh, uh, we'll flip for it. Ducks or clowns.

Chandler: Oh, we're gonna flip for the baby?

Joey: You got a better idea?

Chandler: All right, call it in the air.

Joey: Heads.

Chandler: Heads it is.

Joey: Yes! Whew!

Chandler: We have to assign heads to something.

Joey: Right. Ok, ok, uh, ducks is heads, because ducks have heads.

Chandler: What kind of scary-ass clowns came to your birthday?

"Is economics a science?" and other silly question

There are few debates more annoying than the perennial economics-as-a-science discussion. For one thing, it almost invariably prompts someone to bring out the old "look at our math" argument, apparently unaware that unnecessarily complicated mathematics is a standard trait of pseudo-science (just try talking to an astrologer or a relativity denier).

Worse yet is the idea that being a scientist buys you a certain credibility, that your pronouncements should automatically be given weight because of the lab coat. (There's a reason the FDA doesn't let actors in drug ads dress as doctors any more.) A well-reasoned, well-supported argument from a historian still trumps a stupid one from a scientist.

But if you have to make the classification, it seems obvious to me that economics is a social science, albeit one facing some special challenges (as discussed in this previous post):

Compared to their nearest neighbors, film criticism and economics (particularly macroeconomics) are both difficult, messy fields. Films are collaborative efforts where individual contributions defy attribution and creative decisions often can't be distinguished from accidents of filming. Worse yet, most films are the product of large corporations which means that dozens of VPs and executives might have played a role (sometimes an appallingly large one) in determining what got to the screen.

Economists face a comparably daunting task. Unlike researchers in the hard sciences, they have to deal with messiness of human behavior. Unlike psychologists, microeconomists have few opportunities to perform randomized trials and macroeconomists have none whatsoever. Finally, unlike any other researchers in any other field, economists face a massive problem with deliberate feedback. It is true that subjects in psychological and sociological studies might be aware of and influenced by the results of previous studies but in economics, most of the major players are consciously modifying their behavior based on economic research. It is as if the white mice got together before every experiment and did a literature search. ("Well, there's our problem. We should have been pulling the black lever.")

Faced with all this confusion, film scholars and economists (at least, macroeconomists) both reached the same inevitable conclusion: they would have to rely on broader, stronger assumptions than those colleagues in adjacent fields were using. This does not apply simply to auteurists and freshwater economists. Anyone who does any work in these fields will have to start with some sweeping and unprovable statements about how the world works. Auteurists and freshwater economists just took this idea to its logical conclusion and built their work on the simplest and most elegant assumptions possible, like Euclid demonstrating every aspect of shape and measure using only five little postulates.

(Except, of course, Euclid didn't. His set of postulates didn't actually support his conclusions. The world would have to wait for Hilbert to come up with a set that did. The question of whether economists need a Hilbert will have to wait for another day.)

Having said that, the current debate is several notches above what I expected. Brad DeLong is asking some tough questions about economics not just as a science but as a discipline and we're getting some interesting and insightful comments from scientists in other fields.

This time, it's a discussion worth following.

If you can't say something nice, quote Kaufman

I had started writing this post to complain about a waste-of-space article I had read about on a well-known blog, a complaint I would wrap up with a memorable George S. Kaufman anecdote. As I was looking up the quote, though, it hit me that there is nothing less necessary than journalism complaining about unnecessary journalism.

So here's the good part. You can fill in the rest.

Kaufman was one of three panelists on a live, black-and-white TV show called “This is Show Business.” A performer would come on, tell the panel a problem of his, perform and then return to sit before the panel. Each panelist would then comment on the person’s “problem.” (There is a tantalizing glimpse of the great man on this show, on YouTube.)

On the memorable night, Pfc. Eddie Fisher — in uniform, looking about 16 — laid out his problem. It was a complaint. He said he was appearing at the Copacabana night club and because of his extreme youth and boyish looks, none of the gorgeous showgirls would consent to go out with him. Then he sang, probably, “O Mein Papa” and sat down to receive the panel’s remarks and advice.

It began with “The Gloomy Dean of American Comedy,” as Kaufman had been labeled by someone. (My guess would be the wit Oscar Levant.) Kaufman’s dark countenance as he balefully gazed upon the juvenile Mr. Fisher promised something good — but what? Though I’m working from memory, the thing is so indelible in my mind that I can just about guarantee you that what follows is no more than — here and there — a few words off. At a measured pace, Kaufman began:

Mr. Fisher, on Mt. Wilson there is a telescope. A powerful telescope that has made it possible to magnify the distant stars to approximately 12 times the magnification of any previous telescope. [pause]

And, Mr. Fisher, atop Mt. Palomar, sits a more recently perfected telescope. This magnificent instrument can magnify the stars up to six times the magnification of the Mt. Wilson telescope.

(Where is he going?, I wondered, glued to the screen, back in Nebraska.)

Then:

As improbable as it would doubtless be, if you could somehow contrive to place the Mt. Wilson telescope inside the Mt. Palomar telescope, Mr. Fisher . . . you still wouldn’t be able to see my interest in your problem.

Make that 300... No, make that 400 years

From Edward Glaeser:

The late Senator Daniel Patrick Moynihan of New York is often credited with saying that the way to create a great city is to “create a great university and wait 200 years,” and the body of evidence on the role that universities play in generating urban growth continues to grow. (Disclosure: I work for a university.)

I'm a big believer in more funding for education and research, but as for generating urban growth, the evidence is decidedly Glaeserian.

I'll let Joseph take it from here:

Mark has been discussing Edward Glaeser and his comments on how universities Now, I am a big fan of universities and think that they serve an important role in global economic development. However, I am dubious that they make any particular community prosperous. Consider New Haven, CT -- the home of Yale University (recently ranked the #11 university in the world).

According to wikipedia, the poverty rate in New Haven is 24%, which compares unfavorably with the rest of the United States where it is 14%. The poverty rate in New Haven, despite the presence of Yale, is nearly twice that of the United States as a whole.

Now, one might note that many of the poor residents of New Haven are likely to be students. This is true. But these students still use municipal services and thus require the local tax base to support them (in addition to the long term residents). They do not (after they graduate and make additional income) send money back to New Haven so, in a sense, New Haven is actually subsiding the urban communities that Yale graduates move to.

So, it is actually possible that a large university in a small community could be a drag on the economy due to the lower per capita tax base. Plus, you have a large segment of the population with only a short term interest in the community which may make long term planning more difficult. And New Haven, CT is not the only university town that I can think of with high levels of poverty.

Furthermore, if a strong local university (like the University of Washington) is a solution to urban poverty (as it was presented in the Detroit versus Seattle comparison of Edward Glaeser) then it is unclear why a stronger economy has not grown up around Yale which is a strong school by any measure.

Doesn't Alton Brown have a hand puppet for this?

Andrew Gelman feels he may have the solution to the mystery of why Nathan Myhrvold (billionaire, physicist and former Microsoft CTO) became so fixated on solar cells acerbating global warming that he convinced the authors of Superfreakonomics to include an almost immediately discredited section on the subject.

Aha! Now, I'm just guessing here, but my conjecture is that after studying this albedo effect in the kitchen, Myhrvold was primed to see it everywhere. Of course, maybe it went the other way: he was thinking about solar panels first and then applied his ideas to the kitchen. But, given that the experts seem to think the albedo effect is a red herring (so to speak) regarding solar panels, I wouldn't be surprised if Myhrvold just started talking about reflectivity because it was on his mind from the cooking project. My own research ideas often leak from one project to another, so I wouldn't be surprised if this happens to others too.

Gelman was referring to Myhrvold's writings on modernist cuisine (or what the slightly less trendy call molecular gastronomy) and specifically to this passage, "As browning reactions begin, the darkening surface rapidly soaks up more and more of the heat rays. The increase in temperature accelerates dramatically."

This may explain why Myhrvold had albedo on his mind, but the comments to Gelman's post suggest another mystery: does the change in color actually have a dramatic effect the rate of browning or is the rate primarily driven by other changes such as water boiling away from the surface of the food*?

Is it possible that Myhrvold is, at heart, basically a freakonomist? Someone who, though brilliant and accomplished, is so eager to find examples of important principles that he sees them where they don't apply?

The following clip has nothing to do with anything in this post, but it does feature an exploding turkey which is really cool.




* From Wikipedia:

High temperature, intermediate moisture levels, and alkaline conditions all promote the Maillard reaction. In cooking, low moisture levels are necessary mainly because water boils into steam at 212 °F (100 °C), whereas the Maillard reaction happens noticeably around 310 °F (154 °C): significant browning of food does not occur until all surface water is vaporized.

Time to call a lie a lie

One of the most effective rhetorical tools in the education reform movement is the "we're just in this for the children" chant. The implication, of course, is that the people who disagree with the movement's proposals must not be putting the children first. It is an obviously unfair suggestion but it done a spectacular job quelling potential criticism on the left.

Of course, the vast majority of people on both sides of the debate are there because of a concern for kids. I disagree strongly with Jonathan Chait and Ray Fisman (just to name two) but I have no doubt that both men are motivated by a desire to see young people get a better education. (For the record, that's a courtesy that many of those in the movement, such as Chait, have been reluctant to extend to the other side.)

This concern does not, of course, preclude self-interest. As functional adults we expect people to act out of a mixture of motives. When policemen lobby for more cops on the street or our dentists advise us to schedule more appointments, we know that their advice to us is also in their self-interest but, barring evidence to the contrary, we believe that they are genuinely concerned about us as well.

These two facts, that everybody has mixed interests and that their advice should still be given the benefit of the doubt, need be kept in mind during all debates. Acknowledging these facts goes a long way toward keeping things civil and, more importantly, honest. That's why, in the context of recent events, the behavior of Michelle Rhee has been so difficult to forgive.

Rhee has always played an aggressive game and has gone out of her way to portray her opponents in a negative light, but with the formation of her lobbying group StudentsFirst, Rhee has crossed the line into claiming that only she and her allies have pure motives.

Consider this quote from an interview conducted by the painfully credulous Guy Raz on Weekend All Things Considered:

"Over the last 30 years, the education policy has been driven in this country by lots of special interest groups, including the teachers union," she says. "I think that one of the missing pieces is that there is no organized national interest group that has the heft that the unions and the other groups do who are advocating on behalf of children."

The trouble with proclaiming your own purity is that someone will remember those proclamations when you have to make compromises. Rhee's recent role as an adviser/advocate for various conservative Republican governors has made some of these compromises unavoidable.

The recent debate over Florida's education bill provided an ideal example:

Among the amendments proposed and rejected as poison pills:

Requiring superintendents to offer a written explanation for denying a teacher's contract renewal, if test scores and evaluations make the teacher eligible for the renewal.

Let's take a minute and unpack this. First let's keep in mind that Rhee's philosophy is based on the assumptions that you can largely fix the current problems in education by putting better teachers in the classroom and you can accurately identify those teachers through test scores and evaluations. The teachers being denied these letters are, by definition, the same teachers Rhee says we need to keep in the classroom in order to save our school system.

Unfortunately, the main effect of denying that letter will be to force many of these teachers out of the profession forever. As I explained it before, the problem is asymmetry of information. It is incredibly difficult and disruptive to make staffing changes during the school year. This makes administrators very skittish about hiring a teacher who has been fired elsewhere. The administrators would, however, probably take a chance if they knew that the teacher got good evaluations and produced high test scores but was fired for something like budgetary reasons. In other words, that letter might have determined whether or not the effective teacher remained employable.

The effect here is two-fold: effective teachers who find themselves caught in this trap will have a great deal of trouble finding another job and may have to leave the profession; other effective teachers will see that competence and accomplishment cannot protect them from arbitrary career-ending decisions and will consider leaving the field as well. Either way, the law Rhee endorses causes us to lose more of the teachers Rhee says we need to keep.

To be blunt as a sock full of sand, from the students' standpoint this is all bad. There is no possible benefit. You simply cannot argue that causing effective teachers to leave the classroom is good for kids. Despite Michelle Rhee's titular claim, rejecting that amendment puts students a poor second.

This doesn't Rhee and the Florida GOP don't care about the quality of teachers (I'm sure they do), but it does mean that, in this case, other things mattered more. Things such as the money to be saved by firing teachers who are likely to max out the merit pay system and the power that comes from running the education department like a political machine.

If Michelle Rhee were concerned solely with the interests of children, she would have been actively lobbying for rules like the one in the amendment, rules that furthered her stated goal of having more teachers in the classroom whom she considered competent. But, of course, Rhee has to balance the interests of children against the interests of those she represents, an alliance that includes, among others, educational entrepreneurs who stand to make a great deal of money from proposed reforms and conservative Republicans who see the current conflict as a way of maintaining political power and moving back to a period when the country was on the right track.

I have no doubt that Michelle Rhee's concern for children is genuine. Rhee is a professional educator and it is exceptionally rare to find someone who has spent a career working in schools who doesn't care about kids. Nor does the fact that she has sometimes put other interests above those of students (including a particularly notorious case involving her own children) indicate a lack of concern -- making compromises is a necessary part of being an adult.

The sin here is in the lie, in claiming purity of motive and suggesting that only she was trustworthy. That was unfair to her opponents, provably false and terribly damaging to the discourse. Michelle Rhee should be ashamed of herself for saying it and Guy Raz and the rest of the press corps should be ashamed of themselves for not holding her accountable.

Safety of Energy Sources

Here is an interesting discussion of deaths per terra watt-hour of electricity generated. I have always been surprised that coal plants generate more radioactivity in the surrounding community than nuclear plants do.

I won't vouch for the numbers being perfect, nor do I think that these rates include the risk of massive failures (like a nuclear plant blowing up). On the other hand, the otherwise fairly safe Hydro has a disaster with 170,000 deaths included in it.

This comparison does seem to put the relative level of risk in perspective. Certainly, there is no risk free alternative to power generation and we should really be focused on what non-fossil fuel options we might have.

20 each?

Cory Doctorow's post (via DeLong) on the New York Times' new paywall has me thinking:

New York Times paywall: wishful thinking or just crazy? - Boing Boing: lots of people are going to greet the NYT paywall with eye-rolling and frustration: You stupid piece of technology, what do you mean I've seen 20 stories this month? This is exactly the wrong frame of mind to be in when confronted with a signup page (the correct frame of mind to be in on that page is, Huh, wow, I got tons of value from the Times this month. Of course I'm going to sign up!)

Which means that lots of people will take countermeasures to beat the #nytpaywall. The easiest of these, of course, will be to turn off cookies so that the Times's site has no way to know how many pages you've seen this month

Of course, the NYT might respond by planting secret permacookies, using Flash cookies, browser detection, third-party beacons, or secret ex-Soviet vat-grown remote-sensing psychics. At the very minimum, the FTC will probably be unamused to learn that the Grey Lady is actively exploiting browser vulnerabilities (or, as the federal Computer Fraud and Abuse statute puts it, "exceeding authorized access" on a remote system -- which carries a 20 year prison sentence, incidentally)

I'm running a dual boot operating system (Windows and Linux). Barring Doctorow's recently decanted telepaths, I assume that puts me up to forty a month which is about four times what I expect my monthly demand to be.

A nice post on Education Reform

There is a nice post in the Daily Kos talking about education reform. The whole piece is worth noting but this point seems especially apt:

Those advocating the end of seniority-based retention practices in favor of "performance" based on student test scores have to concede that districts, which must stretch dollars these days like never before, will be tempted to staff their classes in such a way to protect their younger (and, it must be noted, markedly cheaper) staff members.

I will never forget in my third year on the job drawing a Freshman Geography class that felt, on bad days, like a training session for America's Most Wanted. When I half-jokingly teased a counselor about how I managed to draw every wild-eyed boy in the freshman class, she smiled and told me, "But, Steve, we all know how good you are with difficult students."

At the time, I took it for the backhanded compliment that it was. In this brave new world being promoted by the GOP (and an alarming number of Democrats), it would be my ticket to lower pay. Worse yet, it could be my ticket out of the profession.

The worry here is that, in the short term, this approach will save a lot of money. Having a lot of inexpensive and enthusiastic junior teachers will do wonders for budgets (at a time when tax cuts are a priority). While teachers will recognize what is happening, in an environment with unemployment hovering around 10% (and basic things like Health Insurance depending on employment) it is likely that schools will not suffer in the short term. In the long term, the new world of teaching will require much higher pay for equally qualified teachers as we know have to compensate the teachers for the fear and uncertainty in such a system.

Not to mention to concern that class assignments could be used to protect liked but less capable teachers. Do we have a solid plan for preventing this from happening?

Sunday Morning Funnies

Weekend Gaming -- the heated chess/checkers debate

Andrew Gelman joined in the Chess/Checkers debate and added Go to the mix (which was outside of the scope of the original post but is certainly relevant to the discussion). There have been around two dozen comments so far (and Gelman always has unusually thoughtful discussion threads). Definitely worth a look.
