Fact Or Opinion?

What counts as a “fact”? New York State Supreme Court Justice Cynthia Kern’s ruling on the release of the New York City Teacher Data Reports reflects a view very much at odds with the social science research community. In ruling that the Department of Education’s intent to release these reports, which purport to label elementary and middle school teachers as more or less effective based on their students’ performance on state tests of English Language Arts and mathematics, was neither arbitrary nor capricious, Kern held that there is no requirement that data be reliable for them to be disclosed. Rather, the standard she invoked was that the data simply need to be “factual,” quoting a Court of Appeals case that “factual data … simply means objective information, in contrast to opinions, ideas or advice.”

But it is entirely a matter of opinion as to whether the particular statistical analyses involved in the production of the Teacher Data Reports warrant the inference that teachers are more or less effective. All statistical models involve assumptions that lie outside of the data themselves. Whether these assumptions are appropriate is a matter of opinion. Among the key assumptions that are necessary to make inferences about teacher effectiveness from student performance on the state tests are the following:

  • The tests are valid measures of students’ mastery of English Language Arts and mathematics.
  • A student’s performance on the test, which is taken on a particular date, reflects how that student would perform on the test on other dates.
  • The student, classroom and school-level variables taken into account in the value-added model underlying the Teacher Data Reports are appropriate for inferring that a particular teacher caused the test-score gains experienced by that teacher’s students.
  • Test-score gains observed on tests administered in the middle of one year and the middle of the following year can be properly apportioned to the prior-year teacher and the current-year teacher.

The fact that reasonable people might disagree about these assumptions makes clear that they are a matter of opinion. For example, research by testing expert Dan Koretz, Jennifer Jennings and others shows that the tests at issue were subject to score inflation, because they covered an increasingly predictable and small subset of the curricular standards set by New York state, and failed to predict whether students were well-prepared for college and life after high school. Researchers such as economist Jesse Rothstein have questioned whether value-added models such as the ones used in the production of the Teacher Data Reports are able to simulate a “level playing field” in which teachers can be assumed to have equivalent classes of students.

Even the Department of Education’s own contractors have been of different minds about how to apportion gains when students are exposed to two different teachers between last year’s test and this year’s test. Initially, the gains were apportioned based on the number of months of exposure to last year’s teacher and this year’s teacher. But the most recent technical report for the production of the Teacher Data Reports attributes all of the gains between last year’s test and this year’s test to the current-year teacher.

Value-added measures such as the Teacher Data Reports are constructed through a social process involving expert judgments, and there may be a great deal of consensus around many of those judgments. But that doesn’t make the Teacher Data Reports “facts” that are somehow removed from the realm of opinion and assumption. The data don’t create the categories used to label teachers as above or below average; the labels are a matter of opinion.

There are many definitions of the term “fact,” and perhaps the definitions relied on in legal reasoning differ substantially from those used in social and educational research. But State Supreme Court Justice Cynthia Kern’s argument that the Teacher Data Reports are “facts” makes little sense. In my opinion.

I covered Tennessee’s ed beat for Chalkbeat. Here’s what I learned.

For three years, I covered the Statehouse for Chalkbeat Tennessee, reporting on how policies from Nashville trickled down into more than 1,800 public schools across the state.

Now I’m starting back to school myself, pursuing graduate studies aimed at helping me to become a better education journalist. I’m taking with me six things I learned on the job about public education in Tennessee.

1. Apathy is often cited as a major problem facing education. That’s not the case in Tennessee.

I heard from hundreds of parents, educators, and students who were passionate about what’s happening — good and bad — inside of schools. I covered crowded school board meetings and regularly scrambled for an open seat at legislative hearings where parents had filled the room after driving since dawn to beat the opening gavel. Not incidentally, those parents usually came from communities with the “worst” schools and the lowest test scores. While many disagreements exist about the best way to run schools, there is no shortage of people, particularly parents and educators, who care.

2. Tennessee has one of the most fascinating education stories in America.

I’ve had a front-row seat to massive changes in K-12 education under reforms ushered in by Race to the Top — an overhaul being tracked closely well beyond the state’s borders. But the national interest and import doesn’t end with changes stemming from the $500 million federal award. Tennessee is home to some of the nation’s premier education researchers, making its classrooms laboratories for new ideas about pre-K, school turnaround, and literacy instruction, just to name a few. And at the legislature, more lobbyists are devoted to education than to most any other cause. A lot of eyes are on Tennessee schools.

3. The education community is not as divided as it looks.

During the course of just a few years, I watched state lawmakers change their positions on accountability and school vouchers. I witnessed “anti-charter” activists praise charter leaders for their work. I chronicled task force meetings where state leaders who were committed to standardized testing found middle ground with classroom educators concerned that it’s gone too far. In short, a lot of people listened to each other and changed their minds. Watching such consensus-building reminded me that, while there are no simple debates about education, there is a widespread commitment to making it better.

4. Money matters.

Even when stories don’t seem to be about money, they usually are. How much money is being spent on testing, teacher salaries, school discipline reform? How much should be available for wraparound services? Why do some schools have more money than others? Is there enough to go around? Tennessee leaders have steadily upped public education spending, but the state still invests less than most other states, and the disparities among districts are gaping. That’s why more than a handful of school districts are battling with the state in court. Conversations about money are inextricable from conversations about improving schools.

5. Race is a significant education issue, but few leaders are willing to have that conversation.

More than 60 years after Brown v. Board of Education, Tennessee’s schools are largely racially segregated. Yet most policymakers tread lightly, if ever, into conversations about achieving real racial integration. And in many cases — such as a 2011 law enabling mostly white suburban Shelby County towns to secede from the mostly black Memphis district — they’ve actually gone backwards. Then there’s the achievement data. The annual release of test scores unleashes a flurry of conversation around the racial achievement gap. But the other 11 months of the year, I heard little about whether state and local policies are closing those gaps — or contributing to them — or the historical reasons why the gaps exist in the first place. To be sure, state leadership is trying to address some of Tennessee’s shortcomings. For example, the State Department of Education has launched modestly funded initiatives to recruit more teachers of color. But often, race and racism are the elephants in the room.

6. Still, there’s lots to celebrate.

If there were unlimited hours in the day, I could have written thousands of stories about what’s going right in public education. Every day, I received story ideas about collaborations with NASA in Oak Ridge, high school trips to Europe from Memphis, gourmet school lunches in Tullahoma, and learning partnerships with the Nashville Zoo. Even in schools with the steepest challenges, they were stories that inspire happiness and hope. They certainly inspired me.

Grace Tatter graduated from public schools in Winston-Salem, N.C., and received her bachelor’s degree in history from the University of North Carolina. She’s now pursuing a master’s degree in specialized studies at the Harvard Graduate School of Education.

I’m a Houston geography teacher. This is my plan for our first day back — as soon as it arrives

Texas National Guard soldiers arrive in Houston, Texas to aid citizens in heavily flooded areas from the storms of Hurricane Harvey.

Hurricane Harvey has upended so many things here in Houston, where I am starting my third year as a teacher. One of them is the lesson I am planning for the first day of school — as soon as it arrives.

This upheaval is nothing compared to what people across the city have faced, including my students, who have been sending me photos of evacuation boats going past their houses.

But it is fundamental to the task of being a teacher at a time of crisis. As an A.P. Human Geography teacher, my job is to help students make connections between the geography concepts we are learning in class and their real lives: Does Houston look like the models of urban development we study? Does their family history include a migration?

Before the storm, my thinking went like this: I am white and was born in England and most of my students are Hispanic, many with parents who were born in other countries. I was excited for us to share and compare our different stories. My students last year were shocked and fascinated when they discovered that my white, middle-aged father who is a university professor was applying for a green card, just as many of their family members were.

Now, Hurricane Harvey has underlined for me the importance of those real-world connections. As I looked at the photos from my students, I was struck by how geography concepts can affect us in very real — even life-threatening — ways.

I had planned to teach a lesson at the end of the year about how urbanization affects the environment. The lesson looks at how urbanization can exacerbate flooding: for example, how paving over grassy areas can increase the speed with which rain reaches the bayous, causing the water levels to rise faster. I would then have students evaluate different policies cities can adopt to mitigate that risk, such as encouraging the building on brownfield rather than greenfield sites and passing laws to protect farmland — options that have significant benefits but also significant costs.

I have decided to move this lesson up in the curriculum and teach it when we have school again. School is scheduled to start again on Tuesday, though at this stage everything is provisional, as each hour we find out about more families that have had their homes destroyed by the rising waters. It is still unclear how all our staff, let alone students, will get to school.

I am worried that the lesson could re-traumatize students who have experienced so much trauma in the past few days. I know I will need to make an active effort to make students feel comfortable stepping into the hall if they are feeling overwhelmed. However, my experiences with the recent presidential election make me think that this lesson is exactly what some students might need.

After the election, many students were genuinely confused about what had happened. One question in particular was on their minds: How you can you win the popular vote but not the election? We talked through the Electoral College together, and having clarity about what had happened and why it happened seemed to give them a firmer foundation to build on as they processed their emotions. I am hopeful that teaching about flooding will help ground them in a similar way.

This lesson about flooding was once simply another lesson in the curriculum, but now it has taken on a new urgency. In moments of disaster, it is easy to feel powerless; I certainly could not help the people I saw posting on Facebook that they were been on hold with 911 for hours while standing on their roofs.

Yet teachers have a unique power — the power to shape the minds of future generations to solve the problems that we face. Houston’s location means that it will always be susceptible to flooding. But by teaching about the flood I hope I can play a small role in helping our city avoid repeating some of the tragic scenes I witnessed this week.
