The Right To Know What?

Each fall, thousands of runners descend on the Big Apple to run the New York City marathon. They’ve trained hard all year, and give their all on the course. Long after the elite runners have finished, they stream across the finish line in clumps, exhausted at the end of their 26.2-mile journey. In the middle of the pack, as many as eight or 10 runners might cross the finish line in a single second, and nearly 400 in a single minute.

The difference between a time of 4:08:00 and 4:09:00, however, isn’t large enough to be important. It’s the difference between a rate of 9:28 per mile and 9:30 per mile. Given the vagaries of marathon running — the wind, the temperature, the features of the course — it would be unwise to conclude that the runner who crossed the finish line in 4:08:00 is a much better marathoner than the one who finished in 4:09:00.

But the runner with a time of 4:08:00 finished several hundred places ahead of the runner who finished in 4:09:00 — surely that counts for something! Not really, I’d say. We can quantify the difference, both in absolute terms and in relative position, but these differences are not large enough to be meaningful.

The same is true of the information in the Teacher Data Reports recently released in New York City. Small differences in the estimated effects of teachers on their students’ achievement can appear to be much larger, because most teachers are about equally successful with the assortment of students they teach in a given year, regardless of whether those students begin the year as low-achievers or high-achievers. A trivial difference can appear much larger than it actually is, because, like the marathoners, many teachers are “crossing the finish line” at about the same time.

Here’s an example drawn from the 2008-09 Teacher Data Reports. (I chose the example because it’s convenient and have no reason to believe it’s unusual.) In 2009, fifth-graders took New York State’s English Language Arts exam, which consisted of 24 multiple-choice test items and three constructed-response items, which were combined to create a raw score ranging from 0 to 31. The raw scores were then converted to scale scores, which were used to classify individual students into four levels of performance, with Level 3 representing grade-level proficiency. The average student in New York City got 25.5 raw score points out of 31, which in New York City’s scheme represented an average proficiency level of 3.29. (Sounds pretty good, right? Of course, this was before the state wised up that being proficient on the test didn’t mean a student was on track to graduate from high school ready for college.)

The logic of the city’s Teacher Data Reports is to estimate Teacher A’s contribution to his or her students’ test-scores by comparing how other students with the same measured characteristics would be expected to do on the state test, based on their prior achievement and individual and classroom characteristics, with how Teacher A’s students actually did on the test. If Teacher A’s students score at the same level as was predicted by a statistical model, Teacher A is claimed to not “add value” to her students. If Teacher B’s students perform better than expected, Teacher B is said to add value. (And poor Teacher C, whose students score lower than they are predicted to do, is subtracting value, I guess. Maybe we should call him Teacher F.) These “value-added” scores are then ranked, and a teacher is assigned a percentile value representing the percentage of other teachers teaching the same grade and subject who scored below he or she did.

An “average” teacher, according to this calculation, is one whose value-added score is 0. Of the 1,751 NYC teachers with three or more years of experience who received a value-added rating in fifth-grade English in 2008-09, 84 got a score that rounded to .00. Their percentile ratings—the number that’s getting all of the attention in the traditional and neo-tabloids—range from 53 to 58. A tiny shift of .01 in either direction yields an additional 152 teachers, and a percentile rating of 48 to 63. What seems to be a small range of value-added scores could be anywhere from the 48th to the 63th percentile, because the value-added scores in this range are clumped together.

But it’s hard to know whether a shift of .01 in either direction is large or small. How can we tell? Here’s an idea. Suppose that Ruiz had 20 students who took the fifth-grade English test in 2009, and they were at the city average of 25.5 out of 31 raw score points on the test. What if half of the students got one more question right on the test? Doesn’t seem like a big stretch, does it? Just like the variation in the conditions on marathon day, half of the students getting one more question correct on a given test on a given day doesn’t seem out of the realm of possibility.

If this were to happen, Ruiz’s value-added score would rise from 0 to .05. And the percentile range associated with a value-added score of .05 is 75 to 77. All of a sudden, an “average” teacher looks pretty good. And this isn’t due to the margin of error! It’s just because many teachers are about equally effective in promoting student achievement, according to the value-added model in use. A relatively small change in student performance shifts a teacher’s location in the value-added distribution by a surprisingly large amount.

To be sure, this example is based on one year of student test-score data, not multiple years. But that’s what New York State is proposing to rely on in its first year of the new Annual Professional Performance Review process, and it’s what other jurisdictions, such as Washington, D.C., use in their teacher-evaluation systems. And, as with the marathon, the clumping together of teachers is more of an issue in the middle of the distribution than among those in the lead or at the back of the pack. But that’s little consolation to the teachers whose percentile rankings will figure into annual evaluations that will determine whether they’re permitted to continue teaching.

Speaking at Coney Island Feb. 28, Mayor Bloomberg defiantly affirmed the public’s right to know the contents of teachers’ performance evaluations. “Parents have a right to know every bit of information that we can possibly collect about the teacher that’s in front of their kids,” he said.

That statement is utterly ridiculous. There’s no legitimate interest in information about teachers’ private lives if it has no bearing on their professional performance. But here’s something parents do have the right to know: just how fragile value-added measures based on the New York State testing system are. The New York State tests were never intended to be used to rate teachers’ contributions to student learning — and so it’s little wonder they do a pretty poor job of it.

I’m a black male teen in Aurora, and I see how ‘achievement gap’ forms

The author, Ayden Clayton.

Have you ever heard of the achievement gap? Every column, blog or article that I’ve read on this topic has never come from a African-American, let alone an African-American male.

Here is a voice that should be heard: mine.

Recent research from Stanford showed that African-Americans come in behind other students on standardized tests and enrollment in honors to AP and college classes. This is very important because the gap is also prevalent at Rangeview High School in Aurora, where I am a senior.

There really is a problem. Look at the facts: 25.8 percent of African Americans are in poverty according to Census information published in 2013. The problem is how their lives at home are affecting classroom behavior or attention in class. This goes for all races, but the trend is that many of the students with families living in poverty drop out of high school.

“I believe the achievement gap is a multi-level problem in the education system,” English teacher Mr. Jordan Carter, who works at Rangeview and is a mixed minority, told me. “The hardest thing about it is telling people it is a significant problem. We can solve it by devoting time and resources to find the problem and we need to address kids from all backgrounds. Kids with better resources usually do better.”

I see other problems, too. As a student at Rangeview, I’ve been in numerous AP, honors and CCA classes (college courses) throughout my high school career. What I really have noticed were the underprivileged kids being treated differently, almost like the teachers thought of them as troublemakers without even knowing them.

I’ve had many teachers stereotype me about drugs, hip-hop, if I have a dad and more, and it made me pretty uncomfortable to the point where I didn’t want to go to the class. I feel that when issues such as these that occur in the classroom, it makes students of color not want to focus, and teachers could probably use better training on how to teach kids that do not look like them.

Those students would continuously sit in the back of classes, wouldn’t raise their hand, and wouldn’t ask questions. I used to be one of them. It’s not because the urge to not learn, but the discomfort of the setting in the classroom. When you get looked at and thought of like that, you don’t feel welcomed.

It is becoming evident that Rangeview is in need of a serious sit-down with some of our staff, such as the principal, teachers and all administrators. That way, students can see where their minds are and how they are trying to deal with the way they feel about fair conditions in the classroom.

The administrators should also talk to students – particularly minority students – about our wants and needs so we as students can have some input. For the students who are struggling, it would be great to have counselors talk to them and find a way that would help the students improve their academic careers, such as tutoring or staying after school.

I have faced the stereotype of being another dropout who is eventually going to jail, but I use that as inspiration every day. I know that all African-American males and females can make a change by letting our voice be heard.

Although I haven’t been through as much as other African-American students, I’ve been through enough to have my opinion matter. We — as minorities — can also take responsibility to change this problem by staying in school and voting into our government people who will fund impoverished areas.

As a community we need to fight stereotypes together. We either defeat stereotypes together or become the stereotypes ourselves.

Why the phrase ‘with fidelity’ is an affront to good teaching

PHOTO: Alan Petersime

“With fidelity” are some of the most damaging words in education.

Districts spend a ton of money paying people to pick out massively expensive, packaged curriculums, as if every one of a thousand classrooms needs the exact same things. Then officials say, over and over again, that they must be implemented “with fidelity.” What they mean is that teachers better not do anything that would serve their students’ specific needs.

When that curriculum does nothing to increase student achievement, it is not blamed. The district person who found it and purchased it is never blamed. Nope. They say, “Well, the teachers must not have been implementing it with fidelity.”

It keeps happening because admitting that schools are messy and students are human and teaching is both creative and artistic would also mean you have to trust teachers and let them have some power. Also, there are some really crappy teachers out there, and programs for everyone are often meant to push that worst-case-scenario line a little higher.

And if everyone’s doing just what they’re supposed to, we’ll get such good, clean numbers, and isn’t that worth a few thousand more dollars?

I was talking with a friend recently, a teacher at an urban school on the East Coast. He had been called to task by his principal for splitting his kids into groups to offer differentiated math instruction based on students’ needs. “But,” the principal said, “did the pacing guide say to differentiate? You need to trust the system.”

I understand the desire to find out if a curriculum “works.” But I don’t trust anyone who can say “trust the system” without vomiting. Not when the system is so much worse than anything teachers would put together.

Last year, my old district implemented Reading Plus, an online reading program that forces students to read at a pace determined by their scores. The trainers promised, literally promised us, that there wasn’t a single reading selection anywhere in the program that could be considered offensive to anyone. God knows I never learned anything from a book that made me feel uncomfortable!

Oh, and students were supposed to use this program — forced-paced reading of benign material followed by multiple-choice questions and more forced-pace reading — for 90 minutes a week. We heard a lot about fidelity when the program did almost nothing for students (and, I believe quite strongly, did far worse than encouraging independent reading of high-interest books for 90 minutes a week would have done).

At the end of that year, I was handed copies of next year’s great adventure in fidelity. I’m not in that district any longer, but the whole district was all switching over to SpringBoard, another curriculum, in language arts classes. On came the emails about implementing with fidelity and getting everyone on the same page. We were promised flexibility, you know, so long as we also stuck to the pacing guide of the workbook.

I gave it a look, I did, because only idiots turn down potential tools. But man, it seemed custom-built to keep thinking — especially any creative, critical thought from either students or teachers — to a bare minimum.

I just got an email from two students from last year. They said hi, told me they missed creative writing class, and said they hated SpringBoard, the “evil twin of Reading Plus.”

That district ran out of money and had to cut teachers (including me) at the end of the year. But if they hadn’t, I don’t think I would have lasted long if forced to teach from a pacing guide. I’m a good teacher. Good teachers love to be challenged and supported. They take feedback well, but man do we hate mandates for stuff we know isn’t best for the kids in our room.

Because, from inside a classroom full of dynamic, chaotic brilliance;

from a classroom where that kid just shared that thing that broke all of our hearts;

from a classroom where that other kid figured out that idea they’ve been working on for weeks;

from that classroom where that other kid, who doesn’t know enough of the language, hides how hard he works to keep up and still misses things;

and from that classroom where one kid isn’t sure if they trust you yet, and that other kid trusts you too much, too easily, because their bar had been set too low after years of teachers that didn’t care enough;

from inside that classroom, it’s impossible to trust that anyone else has a better idea than I do about what my students need to do for our next 50 minutes.
