  • School Grades For School Grades' Sake

    Written on August 14, 2012

    I have reviewed, albeit superficially, the test-based components of several states’ school rating systems (e.g., OH, FL, NYC, LA, CO), with a particular focus on the degree to which they are actually measuring student performance (how highly students score), rather than school effectiveness per se (whether students are making progress). Both types of measures have a role to play in accountability systems, even if they are often confused or conflated, resulting in widespread misinterpretation of what the final ratings actually mean, and many state systems’ failure to tailor interventions to the indicators being used.

    One aspect of these systems that I rarely discuss is the possibility that the ratings systems are an end in themselves. That is, the idea that public ratings, no matter how they are constructed, provide an incentive for schools to get better. From this perspective, even if the ratings are misinterpreted or imprecise, they might still “work."*

    There’s obviously something to this. After all, the central purpose of any accountability system is less about closing or intervening in a few schools than about giving all schools incentive to up their respective games. And, no matter how you feel about school rating systems, there can be little doubt that people pay attention to them. Educators and school administrators do so, not only because they fear closure or desire monetary rewards; they also take pride in what they do, and they like being recognized for it. In short, my somewhat technocratic viewpoint on school ratings ignores the fact that their purpose is less about rigorous measurement than encouraging improvement.

  • Senate's Harkin-Enzi ESEA Plan Is A Step Sideways

    Written on July 31, 2012

    Our guest authors today are Morgan Polikoff and Andrew McEachin. Morgan is Assistant Professor in the Rossier School of Education at the University of Southern California. Andrew is an Institute of Education Science postdoctoral fellow at the University of Virginia.

    By now, it is painfully clear that Congress will not be revising the Elementary and Secondary Education Act (ESEA) before the November elections. And with the new ESEA waivers, who knows when the revision will happen? Congress, however, seems to have some ideas about what next-generation accountability should look like, so we thought it might be useful to examine one leading proposal and see what the likely results would be.

    The proposal we refer to is the Harkin-Enzi plan, available here for review. Briefly, the plan identifies 15 percent of schools as targets of intervention, classified in three groups. First are the persistently low-achieving schools (PLAS); these are the 5 percent of schools that are the lowest performers, based on achievement level or a combination of level and growth. Next are the achievement gap schools (AGS); these are the 5 percent of schools with the largest achievement gaps between any two subgroups. Last are the lowest subgroup achievement schools (LSAS); these are the 5 percent of schools with the lowest achievement for any significant subgroup.

    The goal of this proposal is both to reduce the number of schools that are identified as low-performing and to create a new operational definition of consistently low-performing schools. To that end, we wanted to know what kinds of schools these groups would target and how stable the classifications would be over time.

  • Labor Market Behavior Actually Matters In Labor Market-Based Education Reform

    Written on July 26, 2012

    Economist Jesse Rothstein recently released a working paper about which I am compelled to write, as it speaks directly to so many of the issues that we have raised here over the past year or two. The purpose of Rothstein’s analysis is to move beyond the talking points about teaching quality in order to see if strategies that have been proposed for improving it might yield benefits. In particular, he examines two labor market-oriented policies: performance pay and dismissing teachers.

    Both strategies are, at their cores, focused on selection (and deselection) – in other words, attracting and retaining higher-performing candidates and exiting, directly or indirectly, lower-performing incumbents. Both also take time to work and have yet to be experimented with systematically in most places; thus, there is relatively little evidence on the long-term effects of either.

    Rothstein’s approach is to model this complex dynamic, specifically the labor market behavior of teachers under these policies (i.e., choosing, leaving and staying in teaching), which is often ignored or assumed away, despite the fact that it is so fundamental to the policies themselves. He then calculates what would happen under this model as a result of performance pay and dismissal policies – that is, how they would affect the teacher labor market and, ultimately, student performance.*

    Of course, this is just a simulation, and must be (carefully) interpreted as such, but I think the approach and findings help shed light on three fundamental points about education reform in the U.S.

  • The Education Reform Movement: Reset Or Redo?

    Written on June 12, 2012

    Our guest author today is Dr. Clifford B. Janey, former superintendent for the Newark Public Schools, District of Columbia Public Schools, and Rochester City School District. He is currently a Senior Weismann Fellow at the Bankstreet College of Education in New York City, and a Shanker Institute board member.

    For too many students, families, and communities, the high school diploma represents either a dream deferred or a broken contract between citizens and the stewards of America's modern democracy. With the reform movement’s unrelenting focus on testing and its win/lose consequences for students and staff, the high school diploma, which should signify college and work readiness, has lost its value.

    Not including the over seven thousand students who drop out of high school daily, the gap between the percentage of those who graduate and their readiness for college success will continue to worsen the social and income inequalities in life. Recent studies report that America has the highest number of people (46.2 million) living in poverty since data collection began in 1959. While poverty and its conditions have been unforgiving, policy makers and education reformers have largely ignored this reality. Rebuttals to this argument are interesting, but, without fundamental change, the predictable growth within the ranks of poverty will continue.

    A framework within which solutions will thrive requires a redo of the national reform focus, not merely a reset of existing efforts—including teacher evaluation systems, closing low performing schools (and opening up new ones that are at best marginally better), and increasing the opportunity for mayoral control (which still commands attention but with little assurance of transparency).

  • Staff Matters: Social Resilience In Schools

    Written on May 7, 2012

    In the world of education, particularly in the United States, educational fads, policy agendas, and funding priorities tend to change rapidly. The attention of education research fluctuates accordingly. And, as David Cohen persuasively argues in Teaching and Its Predicaments, the nation has little coherent educational infrastructure to fall back upon. As a result of all this, teachers’ work is almost always surrounded by important levels of uncertainty (e.g., lack of a common curricula) and variation. In such a context, it is no surprise that collaboration and collegiality figure prominently in teachers’ world (and work) views.

    After all, difficulties can be dealt with more effectively when/if individuals are situated in supportive and close-knit social networks from which to draw strength and resources. In other words, in the absence of other forms of stability, the ability of a group – a group of teachers in this case – to work together becomes indispensable to cope with challenges and change.

    The idea that teachers’ jobs are surrounded by uncertainty made me of think problems often encountered in the field of security. In this sector, because threats are increasingly complex and unpredictable, much of the focus has shifted away from heightened protection and toward increased resilience. Resilience is often understood as the ability of communities to survive and thrive after disasters or emergencies.

  • The Allure Of Teacher Quality

    Written on April 23, 2012

    Those following education know that policy focused on "teacher quality" is by far the dominant paradigm for improving  schools over the past few years. Some (but not nearly all) components of this all-hands-on-deck effort are perplexing to many teachers, and have generated quite a bit of pushback. No matter one’s opinion of this approach, however, what drives it is the tantalizing allure of variation in teacher quality.

    Fueled by the ever-increasing availability of detailed test score datasets linking teachers to students, the research literature on teachers’ test-based effectiveness has grown rapidly, in both size and sophistication. Analysis after analysis finds that, all else being equal, the variation in teachers’ estimated effects on students' test growth – the difference between the “top” and “bottom” teachers – is very large. In any given year, some teachers’ students make huge progress, others’ very little. Even if part of this estimated variation is attributable to confounding factors, the discrepancies are still larger than most any other measured "input" within the jurisdiction of education policy. The underlying assumption here is that “true” teacher quality varies to a degree that is at least somewhat comparable in magnitude to the spread of the test-based estimates.

    Perhaps that's the case, but it does not, by itself, help much. The key question is whether and how we can measure teacher performance at the individual level and, more importantly, influence the distribution – that is, to raise the ceiling, the middle and/or the floor. The variation hangs out there like a drug to which we’re addicted, but haven’t really figured out how to administer. If there was some way to harness it efficiently, the potential benefits could be considerable. The focus of current education policy is in large part an effort to do anything and everything to try and figure this out. And, as might be expected given the enormity of the task, progress has been slow.

  • Ohio's New School Rating System: Different Results, Same Flawed Methods

    Written on March 28, 2012

    Without question, designing school and district rating systems is a difficult task, and Ohio was somewhat ahead of the curve in attempting to do so (and they're also great about releasing a ton of data every year). As part of its application for ESEA waivers, the state recently announced a newly-designed version of its long-standing system, with the changes slated to go into effect in 2014-15. State officials told reporters that the new scheme is a “more accurate reflection of … true [school and district] quality."

    In reality, however, despite its best intentions, what Ohio has done is perpetuate a troubled system by making less-than-substantive changes that seem to serve the primary purpose of giving lower grades to more schools in order for the results to square with preconceptions about the distribution of “true quality." It’s not a better system in terms of measurement - both the new and old schemes consist of mostly the same inappropriate components, and the ratings differentiate schools based largely on student characteristics rather than school performance.

    So, whether or not the aggregate results seem more plausible is not particularly important, since the manner in which they're calculated is still deeply flawed. And demonstrating this is very easy.

  • Beware Of Anecdotes In The Value-Added Debate

    Written on March 15, 2012

    A recent New York Times "teacher diary" presents the compelling account of a New York City teacher whose value-added rating was 6th percentile in 2009 – one of the lowest scores in the city – and 96th percentile the following year, one of the highest. Similar articles - for example, about teachers with errors in their rosters or scores that conflict with their colleagues'/principals' opinions - have been published since the release of the city’s teacher data reports (also see here). These accounts provoke a lot of outrage and disbelief, and that makes sense – they can sound absurd.

    Stories like these can be useful as illustrations of larger trends and issues - in this case, of the unfairness of publishing the NYC scores,  most of which are based on samples that are too small to provide meaningful information. But, in the debate over using these estimates in actual policy, we need to be careful not to focus too much on anecdotes. For every one NYC teacher whose value-added rank changed over 90 points between 2009 and 2010, there are almost 100 teachers whose ranks were within 10 points (and percentile ranks overstate the actual size of all these differences). Moreover, even if the models yielded perfect measures of test-based teacher performance, there would still be many implausible fluctuations between years - those that are unlikely to be "real" change - due to nothing more than random error.*

    The reliability of value-added estimates, like that of all performance measures (including classroom observations), is an important issue, and is sometimes dismissed by supporters in a cavalier fashion. There are serious concerns here, and no absolute answers. But none of this can be examined or addressed with anecdotes.

  • The Persistence Of Both Teacher Effects And Misinterpretations Of Research About Them

    Written on January 8, 2012

    In a new National Bureau of Economic Research working paper on teacher value-added, researchers Raj Chetty, John Friedman and Jonah Rockoff present results from their analysis of an incredibly detailed dataset linking teachers and students in one large urban school district. The data include students’ testing results between 1991 and 2009, as well as proxies for future student outcomes, mostly from tax records, including college attendance (whether they were reported to have paid tuition or received scholarships), childbearing (whether they claimed dependents) and eventual earnings (as reported on the returns). Needless to say, the actual analysis includes only those students for whom testing data were available, and who could be successfully linked with teachers (with the latter group of course limited to those teaching math or reading in grades 4-8).

    The paper caused a remarkable stir last week, and for good reason: It’s one of the most dense, important and interesting analyses on this topic in a very long time. Much of the reaction, however, was less than cautious, specifically the manner in which the research findings were interpreted to support actual policy implications (also see Bruce Baker’s excellent post).

    What this paper shows – using an extremely detailed dataset and sophisticated, thoroughly-documented methods – is that teachers matter, perhaps in ways that some didn’t realize. What it does not show is how to measure and improve teacher quality, which are still open questions. This is a crucial distinction, one which has been discussed on this blog numerous times (also here and here), as it is frequently obscured or outright ignored in discussions of how research findings should inform concrete education policy.

  • The Year In Research On Market-Based Education Reform: 2011 Edition

    Written on December 8, 2011

    ** Also posted here on 'Valerie Strauss' Answer Sheet' in the Washington Post

    If 2010 was the year of the bombshell in research in the three “major areas” of market-based education reform – charter schools, performance pay, and value-added in evaluations – then 2011 was the year of the slow, sustained march.

    Last year, the landmark Race to the Top program was accompanied by a set of extremely consequential research reports, ranging from the policy-related importance of the first experimental study of teacher-level performance pay (the POINT program in Nashville) and the preliminary report of the $45 million Measures of Effective Teaching project, to the political controversy of the Los Angeles Times’ release of teachers’ scores from their commissioned analysis of Los Angeles testing data.

    In 2011, on the other hand, as new schools opened and states and districts went about the hard work of designing and implementing new evaluations compensation systems, the research almost seemed to adapt to the situation. There were few (if any) "milestones," but rather a steady flow of papers and reports focused on the finer-grained details of actual policy.*

    Nevertheless, a review of this year's research shows that one thing remained constant: Despite all the lofty rhetoric, what we don’t know about these interventions outweighs what we do know by an order of magnitude.
