Teachers model off their real-world approaches to teaching math

Math teachers Amy Hogan, of Brooklyn Technical High School, and Ellie Terry, of the High School of Telecommunication Arts and Technology, present an election modeling project their students worked on last fall.

How much voting power does a New Yorker really wield? How can statistics presented by the media manipulate readers? How do you raise sweatshop wages without sacrificing profit?

These are a few of the questions that math teachers in New York City are asking their students as they try to bring complex and abstract concepts to life. To answer them, students must supplement the equations and formulas found in textbooks by grappling with real-world applications.

The lessons cover a mathematical practice known as modeling that has been around for decades but is now getting a closer look in schools around the city as teachers try to align their math lessons to Common Core standards that require real-world applicability.

Using modeling to present lessons is one of two instructional focuses that the Department of Education has laid out this year for math teachers.

“It’s the practice of solving real-world problems,” said Brooklyn Technical High School’s Patrick Honner, a teacher at Brooklyn Technical High School who in December won a $10,000 award for an innovative math lesson he developed.

In the prize-winning lesson, Honner had students design hats out of paper materials. At the beginning of the unit, Honner’s students measured the dimensions of one half of a sphere, then had to create hats that contained the exact same area. At the end of class, the students presented their hats in a fashion show.

Honner was one of several teachers who showed off their modeling lessons to colleagues late last year in 10-minute TED talk–style presentations at the headquarters of Math for America, an organization that offers fellowships to math teachers. The group is preparing to open the fellowships up to science teachers as well and has even caught the attention of Gov. Andrew Cuomo, who wants to replicate its stipend model to reward top-performing teachers.

While the city is encouraging math teachers to tackle modeling, in some ways the practice is at odds with the way that the city and state assess students. In a presentation called “g=4, and Other Lies the Test Told Me,” Honner showed slides of test questions that showed what he said were flawed approaches to solving math problems.

Elisabeth Jaffe of Baruch College Campus High School turned to an unusual source for a two-and-a-half-week algebra unit: newspapers.

“I felt like our students are not aware enough of current events,” said Jaffe, one of 97 teachers from around the country to win the prestigious Presidential Award for Excellence in Mathematics and Science Teaching in 2012. “You’ll ask them, ‘Who’s the vice president?’ and they won’t know, which is sad and depressing.”

Jaffe said she asked herself, “How can I relate it back to math in a really clear way?”

Jaffe created a website and assigned her students to read articles in the New York Times, focusing on the economics stories that packed many numbers into the stories. Then they had to compare them with the raw data to determine if the stories fairly represented the statistics. On the website, students wrote their critiques.

In another presentation, Amy Hogan, from Brooklyn Tech, and Ellie Terry, from High School of Telecommunication Arts and Technology, shared a unit they had recently wrapped up in time for the 2012 presidential election. The students studied the country’s electoral college and examined and mapped on a graph how many votes each state received compared with its total population. They found that California, Texas, and New York had many electoral votes but had less power per voter compared to the voters who contribute to Wyoming’s four electoral votes.

“There was a lot of Nate Silver adoration,” said Hogan, referring to the statistician whose model accurately predicted the election results.

While many of the teachers taught in selective high schools, Mohammed Aminyar, a teacher at East Side Community High School, which has more students eligible free and reduced lunch, said modeling worked in his classroom as well. He said his students responded to data that addressed social issues and inequities. His class has looked at the housing market in post-Katrina New Orleans, Iraq War casualties, and prices of MTA subway cards.

One project assigned students to look at the earning sheets of a fictitious shoe company that used sweatshop labor in South America and asked them to come up with a way to raise the workers’ wages without giving up too much profit.

“When it comes to justice, the students are really kind of, like, up in arms about what’s fair and what’s not fair,” said Aminyar.

Hiring more security officers in Memphis after school shootings could have unintended consequences

Tennessee’s largest district, Shelby County Schools, is slated to add more school resource officers under the proposed budget for next school year.

Superintendent Dorsey Hopson earmarked $2 million to hire 30 school resource officers in addition to the 98 already in some of its 150-plus schools. The school board is scheduled to vote on the budget Tuesday.

But an increase in law enforcement officers could have unintended consequences.

A new state law that bans local governments from refusing to cooperate with federal immigration officials could put school resource officers in an awkward position.

Tennessee Education Commissioner Candice McQueen recently reminded school personnel they are not obligated to release student information regarding immigration status. School resource officers employed by police or sheriff’s departments, however, do not answer to school districts. Shelby County Schools is still reviewing the law, but school board members have previously gone on the record emphasizing their commitment to protecting undocumented students.

“Right now we are just trying to get a better understanding of the law and the impact that it may have,” said Natalia Powers, a district spokeswoman.

Also, incidents of excessive force and racial bias toward black students have cropped up in recent years. Two white Memphis officers were fired in 2013 after hitting a black student and wrestling her to the ground because she was “yelling and cussing” on school grounds. And mothers of four elementary school students recently filed a lawsuit against a Murfreesboro officer who arrested them at school in 2016 for failing to break up a fight that occurred off-campus.

Just how common those incidents are in Memphis is unclear. In response to Chalkbeat’s query for the number and type of complaints in the last two school years, Shelby County Schools said it “does not have any documents responsive to this request.”

Currently, 38 school resource officers are sheriff’s deputies, and the rest are security officers hired by Shelby County Schools. The officers respond and work to prevent criminal activity in all high schools and middle schools, Hopson said. The 30 additional officers would augment staffing at some schools and for the first time, branch out to some elementary schools. Hopson said those decisions will be based on crime rates in surrounding neighborhoods and school incidents.

Hopson’s initial recommendation for more school resource officers was in response to the school shooting in Parkland, Florida, that killed 17 people and sparked a wave of student activism on school safety, including in Memphis.

Gov. Bill Haslam’s recent $30 million budget boost would allow school districts across Tennessee to hire more law enforcement officers or improve building security. Measures to arm some teachers with guns or outlaw certain types of guns have fallen flat.

Sheriff’s deputies and district security officers meet weekly, said Capt. Dallas Lavergne of the Shelby County Sheriff’s Office. When the Memphis Police Department pulled their officers out of school buildings following the merger of city and county school systems, the county Sheriff’s Office replaced them with deputies.

All deputy recruits go through school resource officer training, and those who are assigned to schools get additional annual training. In a 2013 review of police academies across the nation, Tennessee was cited as the only state that had specific training for officers deployed to schools.

Teacher Carl Schneider walks children home in 2015 as part of the after-school walking program at Whitney Achievement Elementary School in Memphis. This photograph went viral and inspired a First Person reflection from Schneider in 2017.

Last year, some of our most popular pieces came from readers who told their stories in a series that we call First Person.

For instance, Carl Schneider wrote about the 2015 viral photograph that showed him walking his students home from school in a low-income neighborhood of Memphis. His perspective on what got lost in the shuffle continues to draw thousands of readers.

First Person is also a platform to influence policy. Recent high school graduate Anisah Karim described the pressure she felt to apply to 100 colleges in the quest for millions of dollars in scholarships. Because of her piece, the school board in Memphis is reviewing the so-called “million-dollar scholar” culture at some high schools.

Do you have a story to tell or a point to make? In 2018, we want to give an even greater voice to students, parents, teachers, administrators, advocates and others who are trying to improve public education in Tennessee. We’re looking for essays of 500 to 750 words grounded in personal experience.

But first, check out these top First Person pieces from Tennesseans in 2017:

My high school told me to apply to 100 colleges — and I almost lost myself in the process

“A counselor never tried to determine what the absolute best school for me would be. I wasted a lot of time, money and resources trying to figure that out. And I almost lost myself in the process.” —Anisah Karim     

Why I’m not anxious about where my kids go to school — but do worry about the segregation that surrounds us

“In fact, it will be a good thing for my boys to learn alongside children who are different from them in many ways — that is one advantage they will have that I did not, attending parochial schools in a lily-white suburb.” —Mary Jo Cramb

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

“Apathy is often cited as a major problem facing education. That’s not the case in Tennessee.” —Grace Tatter

I went viral for walking my students home from school in Memphis. Here’s what got lost in the shuffle.

“When #blacklivesmatter is a controversial statement; when our black male students have a one in three chance of facing jail time; when kids in Memphis raised in the bottom fifth of the socioeconomic bracket have a 2.6 percent chance of climbing to the top fifth — our walking students home does not fix that, either.” —Carl Schneider

I think traditional public schools are the backbone of democracy. My child attends a charter school. Let’s talk.

“It was a complicated choice to make. The dialogue around school choice in Nashville, though, doesn’t often include much nuance — or many voices of parents like me.” —Aidan Hoyal

I grew up near Charlottesville and got a misleading education about Civil War history. Students deserve better.

“In my classroom discussions, the impetus for the Civil War was resigned to a debate over the balance of power between federal and state governments. Slavery was taught as a footnote to the cause of the war.” —Laura Faith Kebede
