When Chicago cut down on suspensions, students saw test scores and attendance rise, study finds

As school districts across the country have cut back on suspensions, critics claimed that the changes have led to chaos in the classroom. But there’s been remarkably little hard evidence either for or against that view.

That’s why a new study of Chicago Public Schools is so significant.

It found that a modest drop in suspensions for high-level offenses actually led to small increases in test scores and attendance for all students in a school. The research, recently published in the peer-reviewed Peabody Journal of Education, bolsters the case of discipline reformers who argue that school suspensions are ineffective and disproportionately target students of color.

“Reducing suspension use for severe infractions seems consistent with a set of generally positive but small impacts,” the researchers, Rebecca Hinze-Pifer of Stanford and Lauren Sartain of the University of Chicago, found. There was “no indication students overall experience schools as less safe when suspension use for severe infractions declines.”

Chicago began working to reduce suspensions and other kinds of discipline that pull students out of their classrooms in 2008. Many other cities have followed suit.  

By 2013, the share of severe offenses in Chicago schools that resulted in out-of-school suspensions dropped from 93 percent to 84 percent in high schools. The share of lower-level weapons violations, like having a box cutter, resulting in out-of-school suspensions dropped more sharply. Students often earned in-school suspensions instead, keeping them in their school building but not their specific classrooms.

The researchers try to determine the effects of those changes by comparing the same students in the same Chicago high schools before and after the reductions in suspensions for severe offenses.

They found that the school-wide increase in attendance amounted to about one additional day per school year, beyond the extra days students were in school because they weren’t suspended. The test score gains, while statistically significant, were very small.

Although the suspension changes had no overall effect on students’ perceptions of their schools’ safety, that wasn’t true in all schools. In schools that were predominantly African-American (and which also had the highest suspension rates), students felt much safer after the reforms. But in schools with many Latino students, the opposite was true. The researchers couldn’t determine why.

It’s unclear whether these findings would apply to other school districts, particularly because the drop in suspensions in Chicago was fairly small. The initiative took place before the federal government issued guidance in 2014 pushing districts to reduce suspensions. (Current Secretary of Education Betsy DeVos is considering rescinding this guidance.)

But the study does add to the limited knowledge base on how school discipline reforms affect students. A previous study in Chicago found that efforts to shorten suspensions in high schools boosted attendance, but made schools less safe, according to teachers. Another recent study in Philadelphia found that after the district put in place a policy to limit suspensions, student test scores declined in some schools, but since the policy was largely not implemented, the findings are difficult to interpret.

Hinze-Pifer, the researcher behind the latest study, emphasizes that figuring out the best alternatives to suspensions remains essential.

“It does matter what you do instead,” she said. “We’re not saying do nothing.”

thrown for a loop

Elementary school teachers sometimes follow a class of students from year to year. New research suggests that’s a good idea.

When Kim Van Duzer, an elementary school teacher in Brooklyn, had a chance to follow her students from third to fourth grade the next school year, she jumped at the opportunity.

“It was such a positive experience,” she said. “One of the big advantages is starting in September hitting the ground running — you already know the kids and the things they did the previous year and the things they need to work on.”

Now, a new study seems to confirm Van Duzer’s experience. Students improve more on tests in their second year with the same teacher, it finds, and the benefits are largest for students of color.

Repeating teachers is “a beneficial and relatively low-cost policy that should be given due consideration,” write the researchers, Andrew Hill of Montana State University and Daniel Jones of the University of Southern Carolina.

The paper focuses on North Carolina students in grades 3 to 5 who had the same teacher two years in a row. That usually occurred not when a whole class repeated  with the same teacher — what’s often called “looping” — but with a small share of students ending up with the same teacher twice, for whatever reason.

How much did that second year with a teacher help? The overall effect was very small, enough to move an average student from about the 50th to the 51st percentile. But even this modest improvement is notable for several reasons.

First, it’s a policy that, at least in theory, doesn’t cost anything or require legislation to implement. Schools, if they choose to, could make looping a habit.

Second, the gains were larger for kids of color than for white students, suggesting that this could make a slight dent in longstanding test-score gaps.

Third, the students who saw the biggest gains had teachers who were lower performing overall, suggesting that having the same students twice may be particularly useful for helping teachers improve.

Fourth, it’s an idea that could affect a lot of students. Just being in a class where many peers were repeating with a teacher seemed to benefit kids who were new to the teacher, the study finds. The researchers think that could be because those teachers’ classroom environments improve during that second year with many of the same students.

That aligns with Van Duzer’s experience, when she had a handful of new students in her looped class. “The other kids were really welcoming to them, and they became fully integrated members of our class community,” she said.

Fifth, there may be other benefits not captured by test score gains. For Van Duzer, being able to pick up existing connections with students’ families was another perk. “It takes a school year to fully develop a relationship with kids and their parents — for everybody to get to know each other, to develop trust, to be able to speak really openly,” she said.

One important caveat: the study can’t prove that if looping were expanded, that the benefits would persist. Past research also isn’t much of a guide because there’s so little out there, but what exists is consistent with the latest study.

A recent analysis found students in rural China scored higher on tests as a result of the approach. Here in the U.S., the best evidence might come from what amounts to the reverse of the policy: having teachers of younger students focus on a single subject, and thus not have a single class of students. In Houston, this led to substantial drops in student test scores and attendance.

These studies suggest early grade teachers do better when they “specialize” in a small group of students, rather than a certain academic subject.

To Van Duzer, who now serves as a math coach at her school, having a firm understanding of what students learned the previous year is crucial and helps explain the findings.

“A lot of times when kids move into a new grade, the teachers are like, ‘You learned this last year!’ and the kids are like, ‘We did?’” she said. “But then if you say certain words … you remind them of certain experiences, like ‘Remember when we studied China and we talked about this?’ and then they’re like ‘Oh yeah, I do remember.’ But if you haven’t been there with them for those experiences, it’s harder to activate that knowledge.”

How I Teach

Crazy contraptions, Chemistry Cat, and climbing stories: How this Colorado science teacher connects with kids

Here, in a feature we call How I Teach, we ask educators who’ve been recognized for their work how they approach their jobs. You can see other pieces in this series here.

Shannon Wachowski once started a parent-teacher conference by sharing that she was concerned about the student’s lack of motivation. The boy’s mother quickly began adding criticisms of her own — alarming Wachowski enough that she started defending the teen.

It was then the student’s behavior began to make more sense to Wachowski, who teaches everything from ninth-grade earth science to college-level chemistry at Platte Valley High School in northeastern Colorado. She realized that school, not home, was the boy’s safe place.

Wachowski is one of 20 educators who were selected to serve on the state Commissioner’s Teacher Cabinet. The group provides input to officials at the Colorado Department of Education.

She talked to Chalkbeat about how she uses parent conferences and classwork to learn students’ stories, why making Rube Goldberg contraptions boosts kids’ confidence, and what happens when she raises her hand in the middle of class.

This interview has been condensed and lightly edited.

Why did you become a teacher?
Originally a practicing chemical engineer, I became a teacher because I wanted a more fulfilling career. I had tutored chemistry in college and really enjoyed it.

What does your classroom look like?
Because my students work in teams 90 percent of the time, my tables are arranged so that students can sit in groups of four. I wrote a grant last summer for standing desks so each two person desk raises up and down. They are convenient for labs or when students need a change of scenery. My walls contain student-made license plates (an activity I do on the first day of school) and other student work from class, including various Chemistry Cat memes!

Fill in the blank. I couldn’t teach without my ________. Why?
My heart. Initially I became a teacher because I loved my content. I soon realized however, that while content is important, developing relationships with students is paramount. No learning will happen if positive relationships are not established first. When I am frustrated with student behavior, I try to put myself in their place and respond in a caring and compassionate manner.

What is one of your favorite lessons to teach?
One of my favorite lessons is when my students build Rube Goldberg devices. It gets somewhat chaotic because they are working in teams and materials are everywhere, but every single student is engaged. In the end, they can apply what they know about energy to design a multi-step contraption. I have seen very low-confidence students excel at this activity, and it is very rewarding to see them experience success in a science class.

How do you get your class’s attention if students are talking or off task?
One strategy I’ve recently started using came from my experience leading professional development for other teachers. I will be somewhere in the middle of the room (usually not the front) and raise my hand. When students see me raise my hand, they will raise theirs and pause their conversation. Then other students see those students and raise their hand, etc. Once everyone is quiet, then I’ll make my announcement. Like all other strategies, I need to practice being consistent with it.

How do you get to know your students and build relationships with them? What questions do you ask or what actions do you take?
I always plan the first couple of days for “get to know you” activities. My students design their own paper license plates using whatever letters, numbers, or design they would like. They then have 30 seconds to talk about their license plates.
I noticed that in some of my more challenging classes I needed a way to better connect with my students. At the beginning of most class periods I share some sort of funny story about what happened to me the evening prior — for some reason, I am never short of these stories — or a picture of my dog, or my latest climbing adventure. Sharing this information does not take long and eventually, students will ask if I have a story to share if I haven’t done so in a while. This also leads to them sharing stories with me, and finding that we may have more in common than we think.

Tell us about a memorable time-good or bad-when contact with a student’s family changed your perspective or approach.
At parent-teacher conferences one year I had a parent come in with their student. This student was not the most motivated individual — not disrespectful, just did not seem to want to do anything with his time. As I was explaining this to his parent, the parent started talking very negatively to and about the student, so much so that I found myself trying to defend the student and bring up positive qualities about his character. This interaction helped me to understand some of the student’s behavior in class, as well as realize that for some students, school is their safe place. There are often lots of reasons for a student’s behavior that I may not be aware of, which is why it is important to get to know each student and their situation as best as possible.

What are you reading for enjoyment?
When I have time outside of school, one of the things I enjoy doing is throwing pottery. I am currently reading “Science for Potters” by Linda Bloomfield. It combines my love of science and art into one book.

What is the best advice you ever received?
Since I teach a variety of levels, I often have one class that challenges my classroom management skills. This can be frustrating as I am the type of person that would like to achieve perfection in every circumstance. When I have a discipline issue in my class, I often see it as a personal failure. My husband often reminds me that “You can’t control other people’s behavior, you can only control your response to it.”
