Why Common Core Doesn’t Matter (and Why It Does)

March 25, 2013

I tried taking a break on the blog from writing about Common Core, but the issue keeps popping up.  I tried avoiding writing about Common Core because in most ways it just doesn’t matter.  Let me try to describe why I think this annoying but persistent issue doesn’t matter (and after that I’ll suggest why it still does matter ):

1) Common Core doesn’t matter because standards mostly don’t matter.  Tom Loveless of the Brookings Institution illustrated this point simply and convincingly in the 2012 Brown Center Report on American Education.  Loveless examines variation in the alleged quality of existing state standards to see if higher quality standards are related to academic performance on the NAEP.  They aren’t.  In fact, the correlation between the Fordham Institute’s rating of state standards and NAEP performance is -.06.  Somehow that fact never seems to come up when Fordham is invoked in defense of the quality of Common Core.  Loveless also demonstrates that there is no relationship between “performance standards” (the rigor of cut scores on state tests) and NAEP performance.  Loveless concludes:

Don’t let the ferocity of the oncoming debate fool you. The empirical evidence suggests that the Common Core will have little effect on American students’ achievement. The nation will have to look elsewhere for ways to improve its schools.

Standards mostly don’t matter because they are just a bunch of vague words in a document.  What teachers actually do when they close their classroom door is in no way controlled by those words.  Changing the words in a standards document is very unlikely to dramatically change what teachers do.  As Loveless puts it:

Education leaders often talk about standards as if they are a system of weights and measures—the word “benchmarks” is used promiscuously as a synonym for standards. But the term is misleading by inferring that there is a real, known standard of measurement. Standards in education are best understood as aspirational, and like a strict diet or prudent plan to save money for the future, they represent good intentions that are not often realized….

The intended curriculum is embodied by standards; it is what governments want students to learn. The differences articulated by state governments in this regard are frequently trivial. Bill Gates is right that multiplication is the same in Alabama and New York, but he would have a difficult time showing how those two states—or any other two states—treat multiplication of whole numbers in significantly different ways in their standards documents…. The implemented curriculum is what teachers teach. Whether that  differs from state to state is largely unknown; what is more telling is that it may differ dramatically from classroom to classroom in the same school. Two fourth-grade teachers in classrooms next door to each other may teach multiplication in vastly different ways and with different degrees of effectiveness. State policies rarely touch such differences.

Common Core standards, like other standards reforms, are unlikely to have much of an effect on this enormous variation in what teachers actually teach, how they teach it, and how effective they are.  That variation in actual practice is what causes variation in performance, not a bunch of vague words in a document.

2) The Common Core folks hope to address the ineffectiveness of standards by linking those standards to newly designed assessments and then attaching consequences for individual teachers to those standards-based assessments.  But the level of centralized control over teaching practice to make this work is a political impossibility.  The PLDD crowd  may have gotten almost all states to embrace Common Core standards by dangling federal money and regulatory relief in front  of them in the midst of a financial crisis since, again, those standards are just a bunch of vague words in a document.  But getting states to adopt the newly designed assessments is proving more difficult.  And attaching any meaningful consequences for individual teachers to the results of those new assessments is proving virtually impossible.

The success of Common Core depends on building a centralized machine of assessment and consequences linked to the national standards.  There is no significant political constituency supporting this effort to make sure it is adopted and sustained over time.  Teachers and their unions hate it.  Advantaged parents (the ones with political power) also hate it as they see the the schools and teachers they love lose their autonomy and become cogs in a centralized machine unresponsive to the particular needs and interests of those advantaged parents.  Other than the PLDD crowd in their alphabet soup of reform organizations, who will advocate for and sustain meaningful performance pay for teachers where performance is defined as compliance with centralized mandates?  No one.  And that’s why Common Core will be a political loser.

————————————————————————————

If Common Core is largely unimportant because it is just a bunch of vague words that can never impose the centralized political control to make those words meaningful, why is it still important?

1) Common Core is important because it is a gigantic distraction from other productive reform strategies.  It will probably take about a decade for the failure of Common Core to become obvious to its most important backers.  Until that time Common Core is consuming the lion’s-share of reform oxygen and resources.

2) Common Core is inducing reformers to ignore and even denigrate choice-based reforms because they have to deny one of the central arguments for choice — that there is a legitimate diversity of views on how and what our children should be taught that choice can help address.  If Common Core folks have any support left for choice it is to allow parents to choose the school that can best implement the centrally determined education content.  You can choose which McDonalds franchise you frequent so that they can compete to make the best Big Mac for you, but you are out of luck if you prefer pizza.

3) Common Core enthusiasts support granting dramatically more power to the federal government over education to improve the odds that their centralized machine can be built and implemented.  Even after that fails, the precedence for greater federal involvement will remain, further eroding our decentralized system of education that has long produced benefits through Tiebout choice.

4) Common Core is providing license to all sorts of crazy and contradictory local policies.  Districts are cutting literature, pushing back Algebra, increasing constructivist approaches, reducing constructivist approaches… all in the name of Common Core.  When parents and local voters complain, the schools  dodge accountability by claiming (perhaps falsely) that Common Core made them do it.  A big danger of trying to build a centralized system of controlling schools is that local education leaders will blame the central authority for whatever unpopular thing they choose to do.  It’s like the local Commissar blaming shortages on the central authority rather than his own pilfering.  It shifts the blame.

5) Common Core is bringing out the worst in many of its advocates — people who are not naturally inclined to be hypocrites, sycophants, and dissemblers, but who cannot resist becoming so because of the lure of power, money, and the need to remain relevant.  If you need examples of this, well, you probably haven’t been reading this blog.


The First Thing We Do, Let’s Close All the Middle Schools

March 22, 2013

(Guest Post by Collin Hitt)

The Chicago board of education has announced that it will close 61 elementary schools at the end of the year. This is the largest number of school closures by a district in a single year in U.S. history, according to some reports. And this is just the beginning. Chicago Public Schools reports that 330 of its schools are underutilized; 129 of those schools were finalists for closure this year.

Under its current enrollment, CPS has more buildings than it needs or can afford. Making matters more complicated, enrollment in district-run schools will continue to drop. The city lost 200,000 people over the last decade , and charter schools become more popular every year with families who stay in Chicago. So for years to come, the district will continually be faced with the need to close additional schools. My advice to the district: close your middle schools, for starters.

Recent research suggests that school districts should move away from middle schools, towards the K through 8 elementary schools that were once the norm across the country. The coming consolidation of CPS facilities would allow the district to go back to this model.

Middle schools became prominent in the 1960s and 70s. There was little academic justification for creating them; most of the middle school pedagogy found today was developed after middle schools were built. There wasn’t much anxiety about comingling adolescents and younger children; that was a post hoc justification. Districts simply built middle schools to house sixth through eighth graders from elementary schools that, after the Baby Boom, were actually overfull. Recent research shows that this was a huge unforced error. Districts should have just built more K-8 schools. For students, the transition from elementary to middle schools has negative, long-term impacts.

A pioneering study of middle schools was published in 2010 by Columbia University researchers Jonah Rockoff and Benjamin Lockwood. They compared New York City students at middle schools and K-8 elementary schools. They found that middle schools had a large negative impact on students test scores. Almost all of the learning losses were suffered by disadvantaged students with lower incoming test scores.

Harvard researchers Marty West and Gino Schwerdt have used the same methods to examine Florida middle schools. They found practically identical, negative effects in urban areas like Miami. These effects persisted into high school. Again, disadvantaged students were the ones who suffered the largest learning losses in middle schools, thus widening achievement gaps that reformers usually hope to close.

Middle schools were a mistake in New York and Miami. We have every reason to think they were a mistake in Chicago, too.

In Chicago, school buildings will be shuttered, an unpleasant fact. But the New York and Florida research suggests that there’s an opportunity at hand for CPS.

Consider a typical cluster of three half-empty elementary schools, all of which feed into a half-empty middle school. It’s unaffordable to keep all four schools open indefinitely. Under the status quo, if CPS was to stick with its current grade configurations at its elementary schools, the only feasible way to consolidate schools would be to close one of the K-5 feeder schools. Students would be forced to transfer to one of the other two feeder schools. Then those same students would soon feed into the middle school, which would remain under-enrolled. Some students at consolidated elementary schools will be forced to switch schools twice in as many years, first when their elementary school was closed, next when it was time to transfer to middle school.

The middle-school research points to a different strategy. The district should stop feeding students into half-empty middle schools. Instead, it should allow kids to stay at their current elementary schools by simply adding an older grade to the school. As elementary schools add one grade per year, they’d eventually become K-8 schools — they certainly have the space to do so. Middle schools would shrink in size and staffing levels, since they’d have no more incoming classes.* Eventually, the middle schools would have no more students left, since all of their present students will graduate to high school. In a couple short years, most underused middle schools could be closed.**

Under this scheme, no student would be forced to leave her current school. The district could close a large number of underused buildings. And student performance would improve.

Closing middle schools is not a cure-all. CPS will need to close more buildings than just its middle schools So goes its budget. And the district will need to pursue more than one reform policy – look at its test scores. But it should start with a no-brainer and phase out its middle schools.

* Jonah Rockoff made an excellent point to me when he visited the University of Arkansas, where I work and study, earlier this month. There are a few under-enrolled middle schools that might be led by a better staff than the elementary schools that feed into it. In that instance, you might consider letting that middle school grow from the bottom up, starting with kindergarten. That middle school’s feeder elementary school(s) would receive no new students, eventually phasing itself out as its kids grew into the rare under-enrolled but good middle schools.

** The question then becomes, what to do with the empty buildings? That’s a matter for a future post, though here are some clues.


Constructive Criticism for Common Core Constructivism Deniers

March 21, 2013

(Guest Post by James Shuls)

Let me start by saying that I share most of Jay Greene’s reservations about the Common Core State Standards. Over the past couple of years, I have had the opportunity to discuss these concerns with many Common Core supporters. Although I typically disagree with their conclusions or their logic, I believe Common Core supporters are for the most part sincere in their belief that these standards are rigorous and will improve outcomes for students. However, I find claims that the Common Core State Standards will not influence instructional practices downright disingenuous and obviously false.

In a recent Twitter exchange, the Missouri Department of Elementary and Secondary Education informed me that the CCSS don’t “tell teachers how to teach.” This is a phrase that has been echoing across the country as the Common Core has come under attack from the left and the right.

The fact is that curriculum standards don’t tell teachers how to teach in the same way that a high jump bar doesn’t tell a jumper how to jump. You could theoretically jump over a high jump bar in whatever way you would like; but because of how the jump is structured there is a clear advantage to doing the old Fosbury Flop.

It is clear from documents on the Common Core website and from the discourse throughout the country that these new standards encourage constructivist teaching practices. Take for example these two quotes from a Key Points in Common Core Math document.

  • The standards stress not only procedural skill but also conceptual understanding, to make sure students are learning and absorbing the critical information they need to succeed at higher levels ‐ rather than the current practices by which many students learn enough to get by on the next test, but forget it shortly thereafter, only to review again the following year.
  • Having built a strong foundation K‐5, students can do hands on learning in geometry, algebra and probability and statistics. Students who have completed 7th grade and mastered the content and skills through the 7th grade will be well‐ prepared for algebra in grade 8.

Common Core developers themselves are saying that traditional methods of math instruction aren’t working and students should be learning through “hands on learning.” It is reasonable to assume the tests will likely favor constructivist teaching practices.

I have written extensively about what constructivist teaching looked like in my child’s classroom, where students were supposed to discover how to solve math problems rather than learn to use standard algorithms. My kid’s school is not the exception, it seems to be the rule. Across the country schools are beginning to understand that the Common Core standards will require a more constructivist based form of instruction.

In California, teachers will be “encouraging critical thinking over memorization, focusing on collaboration and integrating technological advances in the classroom.”  We are told that teachers “are attending workshops and training sessions to rethink the way they relay information to students.”

A Virginia newspaper reports, “Discovery, guided math, problem-based learning, project-based learning – call it what you like, it’s here.”

Even in Massachusetts, a state that had arguably better standards than the Common Core, teachers are moving more towards constructivist teaching practices. In the Wrentham School District, “the first and second grade math programs are already implementing new methods for teaching basic math skills that are designed to create deeper understanding of math among the students.” One teacher commented, “Our job as teachers is to guide through questioning.” If that doesn’t sound constructivist, then I don’t know what does.

I am aware that some non-constructivist based curricula, like Saxon Math, are aligning to the Common Core. They are doing so because they have to or they will be at a competitive disadvantage in the marketplace. It remains to be seen if these more traditional models will resist constructivist influences. Much of that depends on how the Common Core assessments are structured.

I am also aware that the standards do not dictate which pedagogical approach a teacher must take. Although, to me it feels a bit like when my mom used to say, “You can do what you want.” Which never really meant that I could do what I wanted.

The bottom line is that the Common Core State Standards are built on constructivist principles and are being implemented, by and large, by constructivist means. If supporters like constructivism, which I suspect most do, then they should just come out and say so. That is not such a difficult position to defend. But don’t attempt to tell me these standards won’t tell teachers how to teach.

What’s in a Name? Memphis Edition

March 20, 2013

Memphis City Council member, Lee Harris, stands in front of the statue of Nathan Bedford Forrest

The names we give to public schools, parks, and buildings matter.  Names provide an opportunity for communities to identify what they hold dear and to remind themselves and teach their children about those values.  As Brian Kisida, Jonathan Butcher, and I argued in an analysis we did of trends in school names, school districts nationwide are more and more frequently missing the opportunity to use school names as a means for praising individuals who embody our cherished values.  Instead, we are now more likely to give schools vague nature names that sound more like herbal teas or day spas (Whispering Hills, Hawk’s Bluff, etc…), than people who we think could serve as models for our children.

Because names are important and because they should reflect community values, if communities change their values they also need to consider changing public names.  There is no doubt that Memphis has changed since it originally named three public parks: Confederate Park, Nathan Bedford Forrest Park, and Jefferson Davis Park.  State legislators in Tennessee, however, were considering a law that would prevent certain name changes.  According to the USA Today:

The “Tennessee Heritage Protection Act of 2013” bill, already introduced in the state legislature, would prohibit name changes to any “statue, monument, memorial, nameplate, plaque, historic flag display,school, street, bridge,building, park preserve, or reserve which has been erected for, or named or dedicated in honor of, any historical military figure,historical military event, military organization, or military unit” on public property…

To pre-empt that legislation the Memphis City Council voted 9-0 to temporarily rename these three parks as Memphis Park, Health Sciences Park, and Mississippi River Park.  They’ve also formed a commission to explore what the new names for these three parks should be.  Let’s hope they break the trend and actually identify individuals who embody values that Memphis holds dear after whom they will name the parks.  There are certainly a large number of great people associated with Memphis or who come from elsewhere who could fit the bill.


New Score: Tom Vander Ark 3, New Gates PLDD Strategy 0

March 19, 2013

The research score continues to run-up in favor of the old Gates education reform strategy of creating small schools of choice rather than the new Gates PLDD strategy of centrally determining what students should be taught (Common Core) and how teachers should be evaluated (Measuring Effective Teachers).  When Tom Vander Ark led the Gates education effort, they had a winning strategy.

The new evidence comes from another paper that was presented at the Association for Education Finance and Policy conference.  Two of my excellent students, Anna Jacob Egalite and Brian Kisida, received a data award from the Kingsbury Center to analyze the effect of school size on student achievement using NWEA test results.  They used a student-fixed-effects research design to see if students improved or worsened their academic achievement when they switched to a school of a different size.  And the results:

We found consistent negative effects of large school size on student math and reading achievement, especially in secondary schools that enroll more than 540 students. In grades 6-10, for example, math achievement declined by -.043 SD (standard deviation) and reading achievement declined by -.024 SD.

If a student moved from a largest quintile school in grades 6-10 to a school in the smallest quintile for those grades, we would expect a 6.4% of a standard deviation improvement in math performance.  Of course, a student fixed effects study is not quite as strong methodologically as the random-assignment evaluation of small high schools in New York City, but it is pretty darn good.  And this study has the advantage of using a large data base of more than 2 million students from across the country.  It’s pretty clear that students would benefit significantly from a reduction on school size — especially junior high and high school students.

Bring back Tom Vander Ark.


Bring Back Tom Vander Ark

March 18, 2013

Under Tom Vander Ark‘s leadership the Gates Foundation pursued an education reform strategy focused on creating smaller high schools.  The theory was that smaller high schools would create tighter social bonds between schools and students, preventing students from slipping through the cracks and increasing the likelihood that they would graduate and go on to college.  Smaller high schools could also be more varied in their approaches and offerings, allowing students to choose schools that best fit their needs.

But around the same time Vander Ark left the Gates Foundation at the end of 2006, the reform strategy shifted.  Rather than fostering small, diverse schools of choice, the Gates Foundation now wanted to build centralized systems of what everyone should be taught (Common Core) and centralized systems of evaluating, training, and promoting teachers (Measuring Effective Teachers).  As I’ve written before, the shift in Gates strategy was not prompted by research.  In fact, the high quality random-assignment study that Gates had commissioned to evaluate the small high school strategy showed strong, positive results.  But the post-Vander Ark leadership at Gates couldn’t wait for the evidence.  The knew the truth without any pesky research and had abandoned the small high schools strategy in favor of their new centralization approach years before those results were released.

Well, the evidence continues to pile up that the Gates strategy under Tom Vander Ark was effective and the new strategy is a failure.  A new National Bureau of Economic Research study by Lisa Barrow, Amy Claessens, and Diane Whitmore Schanzenbach examines the effects of small schools in Chicago.  Just like the earlier random-assignment study of small high schools in New York City had found and like the Vander Ark theory of reform had suggested, small schools promote high school graduation:

We find that small schools students are substantially more likely to persist in school and eventually graduate. Nonetheless, there is no positive impact on student achievement as measured by test scores. The finding of no test score improvement but a strong improvement in school attainment is consistent with a growing literature suggesting that interventions aimed at older children are more effective at improving their non-cognitive skills than their cognitive skills.

As Vander Ark had expected, smaller schools have non-achievement effects, like creating stronger social bonds, that help students go further in their schooling.  And as numerous studies have shown, higher educational attainment is strongly predictive of a host of good outcomes for students later in their lives. Score: Tom Vander Ark 2, New Gates PLDD Strategy 0.

Meanwhile I witnessed further confirmation of the failure of the new Gates approach during a panel at the Association for Education Finance and Policy conference last weekend.  The Gates folks spent more than an hour presenting their Measuring Effective Teachers work.  That stuff may win over gullible policymakers and journalists, but the researchers at AEFP were not impressed.

Tim Sass had the first question and essentially repeated my concerns about how MET fails to provide evidence for the use of multiple measures.  Value-added test scores are predictive of later life earnings, as Chetty, et al have shown, he said, but why should we believe that classroom observations measure anything we care about?  The Gates folks didn’t really have an answer.  Jane Hannaway then articulated my concern that effective teaching may be too context-dependent to lend itself to a single formula for effective practices.  The Gates folks responded that there are probably some basic skills for effective teaching that are useful in all contexts.  They may have a point but that does not address whether MET is getting at those basic skills or not.  The weak correlations of everything in the study suggest they are not finding approaches that are commonly effective.

A third questioner wondered about the cost of adopting the MET approach, especially given the need for multiple observations by multiple, trained raters.  The response was that schools are already spending money on classroom observations but of course that does not address the extra costs of the multiple rater/observations approach.

And lastly William Mathis asked about the generally weak correlations between classroom observations and value-added test scores.  Doesn’t this suggest that these are distinct dimensions of effective teaching that shouldn’t be combined in a single measure, he wondered.  The Gates response surprised me.  They said that the weak correlations were good news.  It is precisely because classroom observations and value-added measures capture different dimensions of effective teaching that we need to combine them in an overall measure.

Of course, this ignores the Sass question about whether we know that the classroom observations are measuring any important aspect of effective teaching.  But more problematic was the “heads I win, tails you lose” nature of their response.  If earlier arguments defending MET were based on how classroom observations and VAM were correlated, then how could the lack of correlation also be presented as proof of MET’s success?  I went up to the Gates presenters after the panel (and chatted with some of them later) and asked them what MET could have found that would have led them to conclude that combining the measures was a bad idea.  They were stumped.  Maybe negative correlations would have dissuaded them from advocating a combined measure, but they weren’t confident about that either.

Essentially, they admitted that the MET policy recommendation is a non-falsifiable claim.  No research finding would have dissuaded them from it.  The ability to falsify a claim is at the heart of science.  MET is not science; it is just politics.  You should have seen the discomfort of the Gates researchers as they pondered why they were presenting non-falsifiable claims as research findings at an academic conference.  This sort of thing corrupts science and has reputational consequences for the researchers who lend their credibility to the new evidence-free Gates reform strategy.

There is a solution to the rot at Gates — Bring back Tom Vander Ark.  At least his ideas were supported by rigorous research.

US Teacher Unions Need to Close the Global Union Corruption Gap

February 27, 2013

The head of Mexico’s teacher union, Elba Esther Gordillo, has been arrested by authorities “on charges of embezzling $200 million.”  She only officially earned $90,000, but still managed to run up about $3 million in charges at Nieman Marcus, another million for property in San Diego, several hundred thousand to an art gallery, endless rounds of plastic surgery (yikes!), etc

It now appears that there is another global comparison on which the US is lagging way behind other countries.  Yes, our teacher unions have folks like Paul Egan, the New York union honcho and testing cheater whose alcohol-fueled tizzy over portion sizes at a swank Albany restaurant caused him to be arrested and led us to advise him that “Fat, Drunk, and Stupid is No Way to Go Through Life, Son.”  And we have “longtime Broward (Fla.) Teachers Union president Tony Gentile admitt[ing]… that he arranged for a sexual tryst with an Internet pal he thought was a 14-year-old girl.”  And also in South Florida, “The longtime leader of the Miami-Dade County teacher’s union pleaded guilty… in a deal after a public corruption task force found he fraudulently charged the organization for up to $650,000 in personal expenses for cruises, vacations and other luxuries.

Is that the best our corrupt teacher union leaders can do?  Just $650,000?  Mexican teacher union leaders can skim off a cool $200 million.  Even all of the abuses cataloged by the vanishing breed of education investigative reports,  Scott Reeder or Mike Antonucci, pale in comparison to Ms. Gordillo… or, as she was known in Mexico, The Teacher.  I suppose that overly-generous and ill-funded teacher pensions begin to approach the scale of malfeasance achieved in Mexico, but that union-directed financial extraction spreads its largess over millions of teachers.  In Mexico a single teacher union boss managed to grab $200 million for herself.  I highly doubt that Randi Weingarten is up to that challenge.

What we have here is a Global Union Corruption Gap.  Maybe we need to draft some cue cards for politicians so they can begin to address this problem with their steakholders.

[Correction — Paul Egan wasn’t actually arrested.  The restaurant called the police because Egan was unruly and refused to pay the bill.  The police ordered Egan to pay.  Jeesh!  Our union bosses even lag behind their colleagues in Mexico on getting arrested!]


These go to Eleven: New Research on KIPP

February 27, 2013

(Guest Post by Collin Hitt)

Mathematica released a major study of KIPP charter schools today. KIPP is primarily a middle school network, with schools across the country. The Mathematica study uses a random-assignment research design, making it at least the eleventh such study we now have on charter schools. It found significant gains in math, positive but insignificant gains in reading. So, again, every random assignment study yet conducted on urban charter schools finds positive effects.

The random assignment study was limited to 13 KIPP charter schools in six states. KIPP’s network is much larger than that. So the authors employed a matching technique in order to evaluate the impact of a larger number of KIPP schools: they compared KIPP students to other kids who on paper were nearly identical. Matching techniques are far less rigorous than lottery-based estimates. But, since Mathematica had lottery-based estimates against which they could compare their matching technique estimates, they were able to validate their matched sample of students as a credible comparison group. They found that their random assignment estimates closely tracked their matching estimates, at relevant schools.

So they employed their matching techniques at a larger sample of 41 schools.  Mathematica then concluded that after just three years in KIPP, students made gains in math, reading, science and social studies that ranged from 8 to 14 months of additional learning. In the parlance of Matt Ladner, “boom.”
