In the classroom

This Memphis teacher wanted to make learning physics more engaging, so he created a website. Now it’s used in 40 countries.

Three girls explode into laughter and cheers as they roll a small cart across the table, successfully getting a rubber band to launch the cart just fast enough to knock a washer off the back of the cart, but not quite fast enough to knock over two washers.

These high schoolers might look like they are just playing with toys inside their Memphis classroom, but they are actually in the middle of a physics lesson. That’s by design.

In his 12 years as a teacher in Memphis, Jack Replinger has worked on perfecting physics lessons that are easy to break down, accessible to students who may not be on grade level in reading and math, and, above all, fun for his students at The Soulsville Charter School in south Memphis. But he’s got another huge aspiration as well: to bring his increasingly popular physics website to as many students and teachers as he can, and to as many countries.

“I was trying to teach the way I had been taught,” Replinger said of his first years in the classroom. “It was boring and a bit of a disaster. Over winter break my second year of teaching, I blew up everything I had learned and said, ‘OK, I’m going to slow this down and move away from teaching long equations.’ That’s when I really started to enjoy teaching.”

Replinger came up with the idea three years ago to take his lessons, which were handed out in his classrooms as thick, paper packets, and turn them into an interactive website, for his students. It’s called Positive Physics. Software engineer Anthony Fizer, who played pick-up basketball with Replinger, helped him get the site running in 2015 and continues to work on the site. Now, more than 6,000 students in 585 schools across 49 states and in 40 countries have used the free website to learn physics. Replinger grew the site’s reach through his postings in teacher-focused Facebook groups and on other social networks.

“I originally wanted to make this because I wanted a website where my students would work that had interesting problems and also didn’t punish them if they are behind in grade level,” Replinger said. “But I think it’s clear it’s hit on a need for teachers elsewhere.”

The website thus far has been mostly self-funded, though he has solicited small donations from friends, family, and via PayPal, and has received some help from the Soulsville Foundation. Replinger said he is now working to find outside investors to keep the website going into the future.

Replinger came to Memphis in 2007 from Seatle as a Teach For America educator, and he was recently named as the winner of the Barbara Rosser Hyde Alumni Leadership Award, a $5,000 award recognizing leadership among the program’s alumni in Memphis.

When Replinger started teaching at Kingsbury High School as part of the teacher training program, he said he struggled to engage his first classes of physics students. He said so much of his first years of teaching was writing problems and grading, that he had little time to design labs such as the rubber band cart experiment. Part of his goal for the website was to prevent other early career educators from going through the same slog.

“For me, this is a chance to say to other teachers, ‘Let me write the problems for you so you can focus on labs,’ he said. “It takes the burden off newer teachers so they can focus on the fun and creative stuff.”

Anna Krueger, a teacher at Hamilton High School, said that the site has taken a “huge load off of my shoulders,” while also guarding against cheating since each student gets different numbers to work with on the same type of problems.

“I feel like this prevents cheating really well and simultaneously encourages teamwork,” Krueger said.

For Replinger, he said the most rewarding part of the site goes back to how it impacts his students. The high schoolers can pace themselves and try homework problems as many times as they like without punishment.

He said one student story stands out as an example of how the site can boost confidence among his high schoolers.

“I had a student last year who saw herself completely not as a math person,” he said. “But she spent a lot of time practicing on the site, and she would even start on homework problems before I had assigned them. She started the class by getting a D on the first quiz. She ended it by getting As at the honors level.”

First Person

I’m a Chicago teacher who has watched many Javions fall through the cracks. Here’s what would help.

As a Chicago Public School teacher and librarian for the past 15 years, I’ve seen many students fall through the cracks.

I remember the young man who sat in my class at the beginning of his senior year, eager to learn. By the end he was failing, having missed over 30 days of school for reasons unknown to me. Or the sophomore girl who transferred out after displaying behavior and academic problems. I saw her years later on the Chicago Tribune’s mugshot webpage.

Both of these students came to mind when I read Adeshina Emmanuel’s story about Javion Grayer, a 16-year-old Chicago student who reads at the second grade level.

What struck me about Javion’s story was that his educational experience was as disjointed as his home life. He switched schools several times, and his family wished someone could help him. But many of the schools he attended did not provide adequate special education services or reading specialists.

This is not a problem unique to Javion. In Chicago Public Schools, a district that prides itself on its variety of choices for families, Javion’s story is an illustration of how little all of those schools can have in common and how little they work together. The result can be students getting a patchwork education within one school district, with little horizontal alignment among schools that serve the same grades, and little vertical alignment among its K-8 schools and high schools.

At Lindblom High School, where I am a teacher librarian, we see transfer students who want to come to Lindblom in search of something better. I watch many transfer students who come with grass-is-greener hopes struggle because of differences in curriculum, instruction, expectations, and school culture. Lindblom is a selective enrollment high school, and many that transfer in are not coming from other selective enrollment schools, which may exacerbate this. But Javion’s experience was probably somewhat similar, watching schools right next to one another operate in very different ways.

Elementary schools that once acted as feeder schools to neighborhood high schools are now feeder schools for every high school in the city. That leaves elementary schools not knowing much about the expectations of the high schools their students will go on to attend, and high schools not knowing exactly what students learned during their elementary experience.

When I taught freshman English for a couple of school years, not once did I know any information about the curriculum my incoming students had used. I didn’t even know what elementary school they came from, let alone their specific struggles or strengths. Think about how much more effective our high schools would be if we actually had that information.

Javion also missed out on something that many CPS children are missing — access to a reading specialist. Reading specialists have been disappearing in the last decade thanks to student-based budgeting, where schools receive budgets based on their enrollment and principals decide how to allocate their funds. If their school’s enrollment is declining, principals often decide to forego a reading specialist to save a teaching position. This does not mean that those positions are not needed; on the contrary, they are very much needed in schools that serve high-needs students like Javion. Those are also often the schools declining in enrollment.

When I started teaching, I experienced the benefits of a reading specialist myself. I was not prepared to teach reading, as much of my teacher education taught me to become a teacher like the ones I had in high school — ones that assigned texts, held discussions, and gave feedback on essays. I knew little of what to do when students didn’t or couldn’t read the assigned text. I quickly discovered that holding a discussion on a chapter that only a few students have read or understood didn’t make for an effective classroom.

It was my school’s reading specialist who taught me how to help students access unfamiliar texts and incorporate a slew of strategies into my classroom.  She also let me know that it’s OK to use class time for reading, and that my students would benefit from me reading aloud to the class, too. My students become better readers, and many of my classroom management issues disappeared, too.

In 2019, to help students like Javion, the district should prioritize addressing both problems. Chicago Public Schools needs to make sure students are learning the same basic reading skills in every school, and that high schools understand what’s being taught to younger students and vice versa.

The district also needs reading specialists to return. I wish that Javion had attended a school where such a specialist could have helped his teachers and worked one-on-one with students who are grade levels behind in reading. He would have been noticed; he would have been helped. I have that same wish for students and teachers across the district.

This Colorado history teacher sees the effects of immigration policy every day — in her worried students

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 the series here.

Some of Kelly Cvanciger’s students at Bear Creek High School in Lakewood live with constant worry — about the possibility of deportation, arrest, or being separated from their families. They are immigrants legally residing in the U.S. through the federal Deferred Action for Childhood Arrivals program, an Obama-era initiative that the Trump administration has sought to end.

“Trying to convince kids to actively participate in their education and learn geography when they face an uncertain future cripples our education system,” said Cvanciger, a history teacher. “It’s just not fair.”

Cvanciger, who was one of six finalists for the 2019 Colorado Teacher of the Year award, talked about how current immigration policies distract students from their studies, why she moved her desk to the back of the classroom, and what she learned from her son, who has autism spectrum disorder.

This interview has been condensed and lightly edited.

Was there a moment when you decided to become a teacher?

I have had some amazing teachers in my life who inspired me as a student. In elementary school it was my fifth grade teacher, Mr. Strong. In high school, it was my French teacher, Ms. Nasvitis. In college, it was Dr. Harry Swanhart. They made me fall in love with education and never want to miss a day. I would cry if my parents told me I was too sick to attend school. I thought teaching was the coolest job because they made teaching look so fun and loved their students. While I temporarily flirted with majoring in veterinary medicine in college, my love of history lured me back to teaching and by my second year of college I was sure that it was my future. I have not looked back since.

Has having a child on the autism spectrum shaped your approach to teaching? If so, how?

Having a son diagnosed with autism opened up an entire new world in terms of understanding how education needs to look different for individual students. My son has taught me that too many people know little to nothing about autism spectrum disorder and that includes the vast majority of teachers who instruct students diagnosed with the disorder. Most do not understand sensory triggers and how students with autism learn. Every child with autism spectrum disorder is unique and their learning styles are more varied than the average mainstream learner.

Because of my son, I have become a better teacher. I taught for 13 years before he was born. He has opened my eyes to learning obstacles that I was otherwise not tuned into, especially for children with developmental disabilities who do not learn from the archaic model of “sage on the stage” teaching.

How do you get to know your students?

I constantly talk to my students and ask them questions so I can cater my examples in class to topics that they can relate to in their lives. Making a connection with each student is important so that they know people care about their lives. Most students are very willing to talk to teachers about their life, family situation, and goals for their future. Some people discredit the relationship-building piece in a classroom, but I believe fostering positive relationships is really the start to opening students up to a world of learning.

Tell us about a favorite lesson to teach. Where did the idea come from?

I love to start teaching with Hammurabi’s Law Code. It is an insightful look into the social and political ideals of the ancient river valley civilization of Mesopotamia. The reason it still has relevance today is that many of the social rules that existed related to birth rights, marriage, gender roles, and societal norms have changed little in over 3,000 years. It provides a useful glimpse into how inflexible social hierarchies really are and defines a foundation for right and wrong for millennium within those societies.

What object would you be helpless without during the school day?

This sounds so simple, but I have a pen in my hand the entire time, and write notes everywhere in my room. It is crucial to document everything in education down to the smallest detail and I always find that I could have taught a lesson differently so I write it down as I am teaching. I have entire notebooks full of “fixes” from years of teaching the same subjects. I always feel an urgent need to record thoughts before they slip away. A pen also helps when teaching as I can make comments specific to each child while students are working.

What’s something happening in the community that affects what goes on inside your class?

I have a lot of students that have “Deferred Action for Childhood Arrivals status” in my classes. The news affects my students on a daily basis. They worry about being deported, being arrested, and being separated from their families. It is impossible to end their worries with our existing immigration policies. Trying to convince kids to actively participate in their education and learn geography when they face an uncertain future cripples our education system. It’s just not fair. We have to find a way to teach students so that they understand their role in society and how they can change their future.

What part of your job is most difficult?

The most difficult part of my job is talking to students who have difficulties in their family situations. It breaks my heart when students come to school and face significant hardships at home through no fault of their own. For students, this presents an obstacle to learning and is a challenge to overcome.

What was your biggest misconception that you initially brought to teaching?

I used to think that all students wanted to learn and come to school since I always wanted to go to school to learn. But when I became a teacher I realized that was the exception, not the norm. Some students grow up with a conception of school as a necessary evil, something they are forced to do because the law says so or their parents say so. Not all students want to learn (at least the subjects they are offered in school), they have too many obstacles to learn, and most dread coming to school for a variety of reasons. No matter how hard I try to get every student to love history, some just never will, and that was a tough lesson.

What are you reading for enjoyment?

I have always been a reader, since I was a little girl. I find that it is the only way to calm my brain in the evenings. I only read two types of books: historical fiction and historical non-fiction. Reading allows me to keep up in my field. Right now, I am reading “The Gulag Archipelago” by Aleksandr Solzhenitsyn and “Stalin: The Court of the Red Tsar” by Simon Sebag Montefiore. Both are challenging reads in their own right, and discuss polarizing views on Stalin’s purges of Soviet-era Russia.

What’s the best advice you’ve received about teaching?

I was reading a study about a decade ago that came to the conclusion that your teacher desk should be at the back of the room. The study concluded that students have a fear of approaching teachers who place their desk at the front of the room because it creates a psychological barrier between the student and teacher, making the student feel inferior to the teacher as a human being. I immediately moved my desk to the back of the room. This was an eye-opening change as students wanted to talk to me more often as I navigated the classroom rather than coming to my desk with questions. By removing the barrier, I built closer relationships between myself and my students.
