A teachable moment?

Tuesday, August 31st, 2010

Complaints about some evaluators not fully understanding our true value …  a sense that points were taken away unfairly, despite reviewer training in the appropriate rubrics  ….  evaluators not understanding, and not crediting us, for the things we do well… a sense that someone in a higher position should reverse the injustice.   It all feels unfair.

Yes, but, most of these Colorado complaints about the round two R2T scoring could also be applied to premature teacher evaluation based upon the inappropriate use of faulty test score data.

Isn’t there some irony in the fact that some of the folks complaining about unfair R2T scoring of Colorado’s application are also among the ones who turned a deaf ear to, or brushed aside, some of the legitimate concerns about using current test scores to evaluate teachers?

My colleague Robert Reichardt made a similar point in April, after Colorado lost round 1 of R2T.  Now we feel twice the pain.

Let me be clear.  I support better teacher evaluation and we need to move in that direction, using multiple measures of better and more frequent principal and peer evaluation, and some appropriate use of student test scores.

There are certainly some individuals and groups who have looked for any reason not to advance real teacher evaluation, because they want to preserve the status quo (which is basically no useful teacher evaluation), and I don’t want to support that position.  At the same time, there are lots of others who see legitimate problems with the current technology that ties student test results to specific teacher evaluations, and want to proceed carefully, in order to do this right.  I was surprised how little attention policy makers gave to that latter group this spring.

As the implementation of SB 191 moves forward into the implementation stage, but now without federal funding to support it, we should keep these concerns in mind.

There are at least four reasons why we can’t now validly and reliably link teacher evaluations to student test scores.  When we address some of these elements, we will be able to more fairly and more effectively evaluate teachers.

First, we don’t have good value-added tests.  A annual March CSAP test is not good enough (you need a valid beginning and end of year test to the same students whose gain you want to assess), and more than half of Colorado grades/subjects don’t even have the annual CSAP available anyway.

Second, students are probably not randomly assigned to teachers, as this evaluation processes requires.  If teacher Jane is known by her principal to be good at teaching students with serious family problems, and thus gets assigned a group of difficult students, and moves their knowledge forward by 0.75 grade levels, while teacher Joan is known to not be good with difficult students, and gets all of the easier ones, and advances their knowledge by 1.0 grade level, who has done a better job?  (It isn’t clear that we can, or want to, “fix” this, but it is a reality that skews the data).

Third, one year of data is not a large enough sample to use for a teacher – you probably need 3.  Classes of 26 students, with 50% mobility levels that are not uncommon in urban areas, leave 13 students with a particular teacher all year – that is not enough data to make a reliable judgment about teacher quality.

Fourth, lots of good teaching is joint and collaborative, especially at the secondary level.   The social science teacher may be as responsible for improved student writing as is the English teacher.  We don’t want teaching to only be a solitary practice with no sharing and collaboration.

Added to these concerns, making student test scores very high-stakes will greatly increase the likelihood of outright cheating, as well as more subtle “teaching to the test” (and not the good kind, where people teach the subjects they are supposed to teach, but the overly narrowing kind where you only ask the types of questions known to be on the test).

I won’t try to make this post double-ironic, but among the beauty of Denver’s own ProComp is that it was put together by and with teachers, and advanced by a teacher vote, and it incorporates multiple measures, to recognize that we can’t really nail down a single dimension of teaching to assess and reward.  It is disappointing that we couldn’t summon that kind of process at the state level.

To see a different way of handling this issue, Chad Aldeman of the Quick and Ed blog (a strongly pro-reform  voice) recently contrasted LA’s handling of teacher data with Tennessee’s approach:

“In contrast, Tennessee has been using a value-added model since the late 1980’s, and every year since the mid-1990’s every single eligible teacher has received a report on their results. When these results were first introduced, teachers were explicitly told their results would never be published in newspapers and that the data may be used in evaluations. In reality, they had never really been used in evaluations until the state passed a law last January requiring the data to make up 35 percent of a teacher’s evaluation. This bill, and 100% teacher support for the state’s Race to the Top application that included it, was a key reason the state won a $500 million grant in the first round.”

At least Denver earns a high score

Wednesday, August 25th, 2010

While we learned that Colorado’s Race to the Top application was ranked 17th out of the 19 finalists by objective reviewers, Denver was ranked 4th out of 30 cities examined in a Fordham Institute report issued yesterday on urban district reform efforts and capacities.

(Fordham probably didn’t realize that the Race to the Top results announcement would dominate this week’s ed news world, but hopefully this urban report will still get the attention it deserves).

New Orleans, with its post-Katrina reform efforts, is ranked #1, followed by Washington, DC and New York City, then Denver.

Urban districts are ranked on their human capital (Denver is 5th here), financial capital (7th), charter environment (8th), quality control (14th), district environment (10th) and municipal environment (4th), for an aggregate Denver ranking of 4th.

As with all such ranking exercises, one can argue with the ratings themselves, the categories or some of the more subjective judgments.   And, a change in superintendent, school board, or mayor can alter these perspectives pretty quickly.

But, this national report does at least support the widely-shared local notion that Denver’s reform efforts are near the cutting edge of national reform, a notion that was shaken by the R2T ratings for Colorado.

Wuz we robbed?

Tuesday, August 24th, 2010

Peer-reviewed, discretionary federal grants, like Race to the Top, are indeed, um,  discretionary.  It will be interesting to see more information about why Colorado “lost” to states like Hawaii (which furloughed students and teachers on Fridays for the past year), Ohio, Maryland, and some others that were not perceived as national reformers (other winners, like Florida, were heavy favorites in any event).

If you think these decisions are mainly political, Colorado should have been a winner, with Senator Bennet in an important political race, a Democratic incumbent governor, and with DPS well-regarded by the Gates Foundation, which has lots of ties with US ED staff.

If you are less cynical, and view these decisions as mostly merit-based, the combination of CAP4K, Colorado’s growth model, local teacher compensation reforms like Procomp, all sealed with the “tough” new teacher evaluation bill, again Colorado should have been a winner.

And, Colorado did try hard to play this game well.   The approach in round 1 included a public participation process that was wider in scope than in any other state, and a clear alliance with the teachers unions, to demonstrate implementation “buy-in.”   When the teacher evaluation process was scored as weak, for round 2 Colorado produced important new legislation, in a tough political fight, that was meant to address that weakness.  Since that fight alienated the union support, it will be ironic indeed if lack of union buy-in is cited as a fatal flaw in the round 2 negative decision.

In any case, this leaves Colorado without the federal financial support that would have been used to jump-start the implementation of several of these reforms.  Given the state and district budget cutbacks already backed into this current fiscal year, and the larger ones looming in fiscal 2011-12, it will be a real challenge to finance these reform efforts.

Who has got some “gifts, grants, and private donations” ?

Summer doldrums are no excuse

Friday, July 16th, 2010

Summer is a wonderful season, and a great chance to relax, on many dimensions. But as I watch my somewhat bored children squabble daily, I wonder about the wisdom of the long summer break, for parents as well as for kids.

And I remember the very solid research on the summer achievement gap, by Karl Alexander and his colleagues. This shows that as much as two-thirds of the K-12 achievement gap can be related to larger, accumulated summer learning losses for low-income students.

It is a little hard to get overly worked up about anything in 90-degree summer heat, but I always think that this is one of our real scandals in education policy.

We know, for sure – combining common sense, good brain theory and solid empirical evidence – that it is bad for students to have a 10-week summer break, in terms of their learning trends, and it is particularly bad for low-income students who don’t get exposed to the summer reading programs, museum visits and education-oriented camps and vacations than many middle-income families enjoy.

Politically, it is also pretty clear why we don’t reduce or eliminate the long summer break for students – many parents don’t like it (when it has been tried in some districts, though surely some parents would like to reduce the hassles of figuring out what to do with kids for 10 weeks of no-school ), the long summer break is traditional, recreational and barbeque industries lobby to preserve it (they really do, just like they have a stake in daylight savings time issues), we don’t want to pay more for more teaching time, many school buildings are not air-conditioned and that would cost more money, etc.

But this is a pretty stark case where we know, with absolute certainty, that our current policies are bad for all students and are especially bad for low-income students. Yet we allow these other political preferences to outweigh the possibility of actually utilizing the known silver bullet of summer learning time. There is a whole organization devoted to this issue.

True, a smattering of good summer intervention programs are targeted at low-income kids, such as this one described recently in EdNews. These efforts are worthy and important but, like voluntary charity generally, there aren’t nearly enough resources to come near solving the whole problem.

A promising recent study suggests that just giving low-income students books might be a cost-effective way to reduce some summer reading loss.

Still, it is frustrating that we don’t seem to want to summon the energy to take this on, full-bore.

College is still a great deal

Tuesday, July 6th, 2010

The lifetime financial rate of return on a college degree has long been very high in the U.S. – much higher than the financial rate of return on other investments available (stock market, real estate, bonds, etc.).

And, of course, many of the best things about a college education and experience can’t be measured in dollars.

There has been some recent concern that rising college costs, rising debt levels for students and a changing job market are reducing the financial returns from college.  But, in the current recession, college graduates have an unemployment rate about half that of the non-college educated workforce.

And, a new study reported in The Wall Street Journal shows that the financial returns to a college investment remain high – about 10 percent on average.

The study, using some great, self-reported compensation data from graduates, also shows costs and earnings by specific institutions. The top rates of return tend to come from top engineering schools and elite universities, but in-state tuition at good state schools remains an excellent investment.

As state higher education funding in Colorado continues to plummet, and as tuition increases more and more, these figures are worth keeping in mind.

Probing how much induction matters

Friday, July 2nd, 2010

In an October 2009 post, I bemoaned the disappointing results of an IES-funded study by Mathematica that found that two years of a comprehensive teacher induction program did not lead to any higher student achievement (or better teacher retention/satisfaction).

This study uses gold-standard methodology, employing random assignment in a large number of schools and districts, so it was particularly frustrating to see no positive results for a policy intervention that many educators “on the ground” see as very important.

Now, Liam Goldrick clues me into the fact that Mathematica has just finished the third year of the evaluation, and there is one new important finding.

For teachers who received  two years of comprehensive induction programs (some in the treatment group received one year, others got two years), in their third year of teaching, their students did significantly better in math and reading than students of teachers who got “normal’ district induction programs.

Now, that third year positive result remains really the only positive finding – teacher retention and satisfaction is no higher, even after three years, and one year of comprehensive induction does not produce better student achievement.  So, the cost/benefit of comprehensive induction, compared to other reforms, remains questionable.

But, it is interesting to see that a common sense policy intervention, which many real world educators are “sure” is important, only pays off after two years of investment.

Many analysts have made the point that we often abandon education reforms quite quickly if they don’t appear to be the “silver bullet,” and the political cycle of new superintendents and school board members accelerates this “policy churn.” (Rick Hess’ 1999 Brookings book “Spinning Wheels: The Politics of Urban School Reform”  explains this argument best).

On some reforms, we might need a little patience.

Here’s a concept: Charter cities

Monday, June 21st, 2010

The idea behind charter schools is to break free from the accretion of bureaucratic and institutional constraints in the world of education that make it difficult to operate an effective school.  And, in practice, many charters (like DSST, West Denver Prep, KIPP) now provide shining examples that low-income students can learn and perform well, despite the various disadvantages they face.

Paul Romer’s idea is to break the institutional constraints of poorly performing countries, by introducing charter cities into their geography.  This idea was recently highlighted in the Atlantic Monthly’s ideas issues:

And it had previously been discussed in forums like Freakonomics.

While critics appropriately point to some potential problems with the idea (it looks like neo-colonialism, what if regimes change or wars break out?), the idea is fascinating.  Basically, a first world country, or consortium of such, would agree to govern a small piece of geography, perhaps a city, in a third world or developing nation.

The institutions, rules, regulations, and laws, and their implementation, would all be from the first world.  Citizens of the developing nation would be encouraged to move to the charter city and try our business and other entrepreneurial ideas in that environment.  The hope is that this would provide an example of success, and would spread beyond the initial limited geography.

It is almost like trying to reproduce the historical accident of Hong Kong near China.  It might also have the advantage of encouraging migration to these areas, rather than to the first world countries that are often increasingly hostile to such in-migration from developing nations.

Of course, the big question with successful charter schools now is whether they can replicate and scale up.  Charter cities, if they can get a toe hold (and Romer has a few countries quite interested) would provide an even more fascinating scale up question.

The nuances of student performance over time

Friday, June 11th, 2010

A fascinating new article in the Journal of Political Economy (link to their working paper version) is receiving a little attention from some smart bloggers like Tyler Cowan and Kevin Drum.

Basically, the article takes advantage of a teaching approach at the Air Force Academy that provides a natural experiment (contemporary economists’ favorite thing – known as “clean causation”).  Calculus is taught there by several different instructors but using the same core ideas, and all the students take a common test at the end – and, students are assigned randomly to the instructors.  Thus, the hidden “quality” of the instructor is fairly well isolated as the cause of any variation in student performance.

The study finds that less experienced and/or lower ranked instructors (e.g., without Ph.Ds) produce higher performance on the final test taken in the semester in which the course is taught – somewhat counterintuitive, but interesting.  The real interesting part, however, is that the students who took the more experienced and more senior instructors may perform lower on the test in that immediate semester, but they perform better in subsequent required math and engineering courses.

That is, the short run performance of students is different from their longer-run performance, depending on the type of instructor they have.

More experienced instructors appear to provide a broader, longer-lasting learning experience, which does not pay off on the immediate standardized test but does pay off in future learning.

Conversely, lower ranked instructors move student achievement higher in the short-run, perhaps by teaching more to the test, but their students perform less well in future courses.

Now, as with all such research, this is only one study, with one type of student examined (smart, hard working, Air Force Academy types), so lots of caveats must be applied.

But, to the extent that this result generalizes about teaching quality, it suggests that even examining student achievement on a good, valid test at the end of a year of learning with a single teacher, which is becoming the hoped-for gold standard of teacher evaluation (though we are a long way from being able to do that, accurately), might not tell you about the long-term impact that teacher has on her/his students’ achievement.

Two sides of teacher evaluation

Friday, June 11th, 2010

Westword’s Melanie Asmar wrote a fascinating article in this week’s edition on teacher evaluation in DPS.

While the larger frame is the toughening of teacher evaluation, the focus is on a particular teacher, Mary Pishney, at Bromwell Elementary. Pishney in many ways sounds like the epitome of a caring, hard-working, student-focused teacher.  A recent negative evaluation by a new principal has sent her life and career into a downward spiral than makes for somewhat painful and poignant reading.

This article can be read, or taken, in many ways.  There are fascinating elements about the widely differing, and intense, parental input about whether Miss Pishney is one of the top teachers anywhere or whether she is overly focused on social/emotional issues and under-emphasizing rigorous first grade math skills.

Certainly the article is skeptical about the quality of the principal’s evaluation of this teacher and the resulting remediation process.  Tom Boasberg and Shayne Spalten are quoted about DPS’s broader need to evaluate teachers more rigorously and to work to remove those who get negative evaluations, and the Johnston bill is discussed.  But, this article points out some the human elements that make it harder to evaluate fairly teacher quality than it might look to someone outside the system.

It’s time for adult conversations on taxes

Monday, May 24th, 2010

With the drama of the legislative session behind us, we should think broadly about Colorado’s future.

Reformers got a lot of legislation they wanted, in the past few sessions – new aligned standards and curricula, greater ability to innovate, meaningful data systems, more rigorous teacher evaluations – but each of these will take money to implement well.

Indeed, if we are to sustain an adequate K-12 education system, and any publicly-funded higher education system at all, much less aspire to the great, and reformed, system many of us would like to see, the state fiscal picture needs to be addressed.  Soon.

Part of that requires an ability of polite people to have adult conversations about taxes.  Not just “NOOO.”

At the national level, according to the U.S Department of Commerce’s Bureau of Economic Analysis, all combined federal, state, and local taxes (including income, sales and property taxes) were 9.2 percent of personal income in 2009, the lowest level since 1950.  That’s right – we now have the lowest effective tax burden we have had in 60 years, and well below the average rate over that period, of 12 percent.

Some would suggest, misleadingly, that today’s tax rates are high, or that economic growth would be choked off by raising taxes.  There have been some very strong periods of American economic growth since 1950, and many of those occurred when effective tax burdens were considerably higher than they are today (and, even more so, effective rates on the highest income Americans are now at long-time low levels).

Moving to the state level, effective state and local tax burdens in Colorado are about 90 percent of the national average across the American states – by becoming just an “average” state, we could bring in about another billion dollars for state investments.  And, Colorado used to be an average state, but the various complex constitutional restraints (with TABOR at the heart) have changed that – over time, the state general fund percentage of total state personal income has fallen from a range of 4-5 percent for the two decades from 1979-1999 to about 3.2 percent today.

These national and state percentages changes may seem small, but since the national GDP is about $13 trillion dollars (and Colorado’s gross state product is about $245 billion), small percentage differences mean large dollars not collected, and thus not available for education and other investments.  The argument that Colorado doesn’t have capacity to invest more in its future just doesn’t hold water – we are in or near the top ten states for per capita income, and our gross state product is about equivalent to the economic capacity of Finland, a nation whose education test results and teacher quality we greatly admire – and Finland spends about twice as much of its tax base on education as does Colorado (including Colorado’s federal support).

Nobody likes to pay taxes – I certainly don’t.  But, in return for paying taxes, you get investments and services.  At the state level, more than 52 percent of the general fund budget in Colorado goes to K12 and higher education, so a conversation about education is also a conversation about tax levels.

As a nation, and even more so as a state, we have moved to a situation where tax levels are probably too low to support the services we want.   It has become political death for aspiring candidates to talk about taxes, probably since Walter Mondale tried it in the presidential election of 1984. TABOR forces politicians to take every case directly to the voters, even more challenging a task, and arguably not a smart idea when polling data shows that many citizen (not surprisingly) want an impossible combination of low taxes and high quality services at the same time.

But, this approach needs to change.  If we are ever going to have a fair and balanced discussion about taxes, and the possibility of raising them, shouldn’t it come at the very time when the burden is the lowest it has been, both nationally and in Colorado, in several generations?

Whatever the outcomes, we need to have adult discussions about the services we want (do we really not want street lights and trash containers in public parks, a la Colorado Springs?  Do we really want the biggest K-12 achievement gap in the nation?  Do we really want the fastest growth in child poverty in America?)  and the reality that we need taxes to pay for services.

Taxes become investments in education, ones that can pay off, over time, in better educated citizens, workers, and yes future taxpayers.
