Building community

Can ‘restorative justice’ happen in math class? One teacher’s idea

At a workshop two weeks ago, Rajihah Coaxum and her fellow teachers ran into a problem. They loved the ideas they were getting — so-called “restorative justice” techniques for turning a classroom into a real community, and helping students resolve differences through dialogue. But given that almost all of teachers’ time is taken up by subject-matter lessons, teachers wondered when they could find time to actually deliver the restorative justice lessons, which aren’t about any academic subject.

Coaxum, who teaches fourth grade at Central Park East 2 elementary school in East Harlem, focused on one technique in particular, called the “centerpiece.” Classroom centerpieces are like table centerpieces, except instead of flowers, they’re made up of symbols of each of the students — like, say, index cards highlighting a person they care about, or a feeling they’re having after a news event, each glued onto a piece of cloth. The goal, as Coaxum learned at the workshop, hosted by the Morningside Center for Teaching Social Responsibility, is to build a sense of community, and a starting point for talking about sensitive topics.

But to make centerpieces useful, Coaxum and other attendees wanted to brainstorm how they could use them as part of an academic lesson. English and history ideas came easily; students could share a favorite book or historical figure. “Math was the one where people could not figure out how to get it in,” Coaxum said. She took that as a challenge: How could she incorporate restorative justice techniques into a math class?

She tried out her concept this week at another workshop, this time one she helped plan through the New York City Math Lab, a new summer training experience for elementary school math teachers, where teachers learn by observing a math class taught to real New York City fifth-graders.

Coaxum used the index card concept — but changed the prompts so that they’d relate to math. On Monday at the math lab, students each filled out an index card with their name and how they see themselves as mathematicians. Tuesday, they each wrote about a problem they worked on that they want to continue thinking about. The responses helped each student share something about his or her identity, just focused on math.

At the end of each day of the weeklong math lab, Coaxum is attaching all the index cards to a single piece of cloth, representing the community they are trying to create. The centerpiece on Tuesday, after one round of contributions:

Coaxum says she’ll keep tweaking the math version of the centerpiece method, which she plans to use next year in her classroom. So far, she’s excited about its potential. “It’s reminding them that everybody has a voice, it’s an inclusive community, and everybody’s thoughts are valid,” she says — important points for any classroom community, math classes included.

Happening at a campus near you: Here’s what the security review of every public school in Tennessee looks like

Sumner County Schools safety coordinator Katie Brown and Gallatin police Lt. Billy Vahldiek examine the window pane in a school hallway to make sure the glass is shatter-resistant. The review team is one of more than a hundred across the state who are conducting security assessments this summer of every Tennessee public school.

Balancing a clipboard in one hand and a coffee tumbler in the other, Katie Brown bends down to inspect a window pane in the hallway of a 10-year-old Tennessee school building.

The glass is shatter-resistant. Check.

Down the hall, Lt. Billy Vahldiek opens an outside exit door and then watches as it latches and locks properly. Check.

Earlier that morning, both Brown and Vahldiek circled the elementary school’s outside perimeter to make sure lighting is adequate, signage is clear, and landscaping doesn’t create blind spots where an intruder could hide.

The pair — one a school safety coordinator, the other a police officer — are teaming up on this day in Sumner County, north of Nashville, to walk through several schools and review security protocols with their principals as part of a statewide review.

“A lot of these schools were built post-Columbine, and some of them are post-Sandy Hook, but none of them are post-Parkland,” said Vahldiek, a Gallatin police officer, chronologically listing three of the nation’s most horrific school shootings.

Aging school facilities and heightened safety concerns are the prime drivers behind Tennessee’s sweeping summertime inspection of all 1,800 of its public school campuses. Gov. Bill Haslam ordered the unprecedented assessment in March following an intruder’s fatal shooting rampage at Marjory Stoneman Douglas High School in Parkland, Florida.

The state’s goal is to identify vulnerabilities that could put Tennessee students and staff at similar risk — and to inform districts how they should use $35 million in safety grants in the months ahead.

Tennessee is among states that responded to Parkland by stepping up their upcoming budgets for thwarting potential attackers. This spring, Haslam and the Legislature doubled to $10 million the amount of recurring annual safety grants — and also provided a one-time investment of $25 million. A share of the money will become available to all 147 districts beginning in July based on Tennessee’s school funding formula — but only after the school systems provide the state with safety inventories of all of their schools.

"It’s a massive undertaking. It’s the first time we’ve ever looked at every school in Tennessee like this."Mike Hermann, Tennessee Department of Education

“It’s a massive undertaking. It’s the first time we’ve ever looked at every school in Tennessee like this,” said Mike Hermann, who is helping to coordinate the review in behalf of the state Education Department.

“Our work is definitely cut out for us this summer,” added Commissioner David Purkey, whose Safety and Homeland Security department is spearheading the initiative. “But there’s a sense of urgency. We want to get it all done by the start of the school year, at least that’s our goal.”

As of this week, about a third of the inspection reports had been submitted — on pace with the state’s timetable. In mid-July, Tennessee will begin accepting applications for the extra spending money.

Most of the one-time grants are expected to further harden school campuses with improvements like upgraded security cameras, fixing or replacing broken locks or outdated doors, and beefing up front entrances. The smaller annual funding could be tapped to hire law enforcement officers to police some campuses, though the money is a drop in the bucket toward providing coverage for every school. There’s also opportunity to invest in mental health services if that’s identified as a local priority.

The money will only go so far. Still, officials believe the safety review lays the groundwork for next steps.

“It’s an excellent opportunity for schools to make an honest appraisal of where they are with security,” Hermann said. “And we’re going to have a much clearer picture of where we are statewide so that future action by the next governor and General Assembly can be based on a higher level of information.”

The reviews are conducted by local teams who participated in regional trainings provided by the state Safety and Homeland Security Department. Comprised of school personnel and local law enforcement, each two-person team follows an 89-point checklist of risks and precautions based on national standards developed by the U.S. Department of Homeland Security.

On-site security reviews are being conducted in schools statewide this summer under an order from Gov. Bill Haslam.

Depending on the building’s age and size, each review usually take two to three hours as inspection teams meet with the principal and inspect the physical facility. Can a school control access to the building? Do all staff wear photo identification badges on campus? Do teachers keep their classroom doors locked?

“The days of propping open doors on a pretty day are gone,” said Brown as she and Vahldiek went through the checklist during one inspection.

The teams also document the availability of personnel for security and for student support services such as school psychologists, as well as relationships with local law enforcement and healthcare providers. Finally, they submit their reports to the state and include copies of each school’s emergency plans and its drill logs from the previous year.

Unfortunately, summertime does not lend itself to seeing a school on a typical school day. For now, the buildings are mostly empty of students and staff as classrooms are painted, floors are waxed, and maintenance performed. But Brown views school break as a good time to look at the nitty-gritty details and to have thoughtful, unrushed conversations with school leaders that should trickle down to faculty and staff.

“We absolutely are taking this seriously,” said Brown, who is coordinating 46 reviews for Sumner County Schools.

“Most things on the checklist are not requirements or codes; they’re recommendations and best practices,” she said. “But this raises our awareness. It reinforces the good things we’re already doing. And it will inform how we use the safety grants.”

I’ve spent years studying the link between SHSAT scores and student success. The test doesn’t tell you as much as you might think.

Proponents of New York City’s specialized high school exam, the test the mayor wants to scrap in favor of a new admissions system, defend it as meritocratic. Opponents contend that when used without consideration of school grades or other factors, it’s an inappropriate metric.

One thing that’s been clear for decades about the exam, now used to admit students to eight top high schools, is that it matters a great deal.

Students admitted may not only receive a superior education, but also access to elite colleges and eventually to better employment. That system has also led to an under-representation of Hispanic students, black students, and girls.

As a doctoral student at The Graduate Center of the City University of New York in 2015, and in the years after I received my Ph.D., I have tried to understand how meritocratic the process really is.

First, that requires defining merit. Only New York City defines it as the score on a single test — other cities’ selective high schools use multiple measures, as do top colleges. There are certainly other potential criteria, such as artistic achievement or citizenship.

However, when merit is defined as achievement in school, the question of whether the test is meritocratic is an empirical question that can be answered with data.

To do that, I used SHSAT scores for nearly 28,000 students and school grades for all public school students in the city. (To be clear, the city changed the SHSAT itself somewhat last year; my analysis used scores on the earlier version.)

My analysis makes clear that the SHSAT does measure an ability that contributes to some extent to success in high school. Specifically, a SHSAT score predicts 20 percent of the variability in freshman grade-point average among all public school students who took the exam. Students with extremely high SHSAT scores (greater than 650) generally also had high grades when they reached a specialized school.

However, for the vast majority of students who were admitted with lower SHSAT scores, from 486 to 600, freshman grade point averages ranged widely — from around 50 to 100. That indicates that the SHSAT was a very imprecise predictor of future success for students who scored near the cutoffs.

Course grades earned in the seventh grade, in contrast, predicted 44 percent of the variability in freshman year grades, making it a far better admissions criterion than SHSAT score, at least for students near the score cutoffs.

It’s not surprising that a standardized test does not predict as well as past school performance. The SHSAT represents a two and a half hour sample of a limited range of skills and knowledge. In contrast, middle-school grades reflect a full year of student performance across the full range of academic subjects.

Furthermore, an exam which relies almost exclusively on one method of assessment, multiple choice questions, may fail to measure abilities that are revealed by the variety of assessment methods that go into course grades. Additionally, middle school grades may capture something important that the SHSAT fails to capture: long-term motivation.

Based on his current plan, Mayor de Blasio seems to be pointed in the right direction. His focus on middle school grades and the Discovery Program, which admits students with scores below the cutoff, is well supported by the data.

In the cohort I looked at, five of the eight schools admitted some students with scores below the cutoff. The sample sizes were too small at four of them to make meaningful comparisons with regularly admitted students. But at Brooklyn Technical High School, the performance of the 35 Discovery Program students was equal to that of other students. Freshman year grade point averages for the two groups were essentially identical: 86.6 versus 86.7.

My research leads me to believe that it might be reasonable to admit a certain percentage of the students with extremely high SHSAT scores — over 600, where the exam is a good predictor —and admit the remainder using a combined index of seventh grade GPA and SHSAT scores.

When I used that formula to simulate admissions, diversity increased, somewhat. An additional 40 black students, 209 Hispanic students, and 205 white students would have been admitted, as well as an additional 716 girls. It’s worth pointing out that in my simulation, Asian students would still constitute the largest segment of students (49 percent) and would be admitted in numbers far exceeding their proportion of applicants.

Because middle school grades are better than test scores at predicting high school achievement, their use in the admissions process should not in any way dilute the quality of the admitted class, and could not be seen as discriminating against Asian students.

The success of the Discovery students should allay some of the concerns about the ability of students with SHSAT scores below the cutoffs. There is no guarantee that similar results would be achieved in an expanded Discovery Program. But this finding certainly warrants larger-scale trials.

With consideration of additional criteria, it may be possible to select a group of students who will be more representative of the community the school system serves — and the pool of students who apply — without sacrificing the quality for which New York City’s specialized high schools are so justifiably famous.
