How do teachers captivate their students? Here, in a feature we call How I Teach, we ask great educators how they approach their jobs. You can see other pieces in this series here.

Cheryl Mosier’s favorite lesson about the properties of light waves is one that her students enjoy, too. Some spend all day Snapchatting about it.

But the lesson also brings up painful memories for the Columbine High School earth science teacher because she was teaching it the day of the deadly shooting there in 1999.

Mosier stopped teaching the lesson for a few years, but ultimately brought it back into the mix. In fact, a video of that lesson was part of the package that earned her the Presidential Award for Excellence in Math and Science Teaching in 2007.

Mosier shared her thoughts on how she builds relationships with students, why she’s always nice to custodians and secretaries, and what she reads for fun.

This interview has been condensed and lightly edited.

Why did you become a teacher?

I first taught when I volunteered at my local swimming pool during swim lessons. I knew then that teaching fit my personality as I had the ability to have fun and teach content. During high school, I was inspired by my math and science teachers (Ms. Finnegan and Ms. Chaloupka) as they were able to make math and science accessible for all students.

Fill in the blank. I couldn’t teach without my ___________Why?

My husband. He teaches literally next door to me, and teaches earth science. We collaborate on everything and help each other solve problems as they arise. We are each other’s sounding boards and he keeps me sane and I keep him thinking outside the box. He hates it when I attend a conference or meeting because I make him change something else.

What is one of your favorite lessons to teach? How did you come up with the idea?

Fingerprints of Light — on spectroscopy — is honestly my favorite, but also my most dreaded. I was teaching that lesson on April 20, 1999, so it took me a couple of years to do it again with students.

During the 2007 school year, I applied for the Presidential Award of Excellence in Mathematics and Science Teaching, and this lesson was the one my husband filmed for the application. I found out a year later that I was the awardee, so this lesson holds a special place in my heart.

Another reason I love this lesson is seeing the excitement of my students. We use the diffraction grating in “Rainbow Peepholes” — small disks with the grating in the middle to look through — which act as tiny prisms splitting the light into the basic wavelengths. This is the one lesson that is Snapchatted all day long – they love taking pictures of the different lights and make some amazing stories.

How do you respond when a student doesn’t understand your lesson?

Students typically collaborate in class and have the opportunity to retake quizzes and tests in an effort to help them learn the content rather than just do the work. When they don’t understand they ask someone – a friend or me to help them figure it out.

My students have to adjust to my style, though, as I make them tell me where in their work their understanding broke down. They have to be able to specifically state where they are stuck, rather than just saying “I don’t get it” because I will ask them “What don’t you get? Show me where you got stuck.” Larger issues of learning styles are managed on an individual basis as I know that not every student can learn from watching videos. So those get addressed as needed and as students recognize what does and doesn’t work for them.

How do you get your class’s attention if students are talking or off task? To a casual observer, my students are constantly off task in my room, because they are working collaboratively. Freshmen are very social creatures, and need to be able to interact with each other. At the beginning of the year, I train them in the major tasks for each class, so they know what to expect each block.

If I need to, I’ll put a phone in “phone jail” if they are being distracted by it, but this isn’t very often. One trick I use at the beginning to refocus them is to raise my hand, as they raise their hand, they close their mouth and pass the message to others. Sounds cheesy, but it’s super effective as they are learning how to manage my class.

How do you get to know your students and build relationships with them? What questions do you ask or what actions do you take?

Every fall, students fill out a Who Am I form that I stole from Pinterest. They get to see my responses and ask me questions, allowing them to get to know me as a human being.

I also have them write down anything I might need to know as a teacher about them, past what is in their school records, similar to the #Iwishmyteacherknew campaign. This opportunity gives me perspective on their individual needs and helps me understand what they might get overwhelmed by each year, or what they might need differently for science learning. As each class is mostly work time, this allows me to interact with my students answering questions, clarifying directions and listening to their conversations.

Tell us about a memorable time — good or bad — when contact with a student’s family changed your perspective or approach.

One of the main reasons I do my own version of #Iwishmyteacherknew is because of an interaction I had with a family in May last year. I had struggled with a particular student all year long, his behavior was obnoxious daily and he constantly was off task, pulling others off task with him and generally working towards being removed from his peers every block as he just couldn’t handle being in the room.

In May, the family requested a meeting with teachers and the counselor, where we found out that this student has Aspergers. Had I known that, our interactions would have been different because I would have known more about him and his needs as a learner and human in society. Once I heard this, we were able to work with each other each day, instead of constantly playing tug-of-war.

What are you reading for enjoyment? I tend to read teen dystopian novels, because they are fun and fast reads with a bit of science fiction mixed in. I also like to read books that my son might enjoy, even if it takes him months to try one, only to realize Mom was right and the book is lots of fun to read!

What’s the best advice you ever received? In my first teaching job, I was told to never make the custodian or secretary mad at you as they can make your life miserable. This has stayed with me, because it’s so amazingly true. My room is typically cleaner than others because I smile and talk with the custodian. I can talk my way into “favors” with the office staff because I know our school would quickly fall apart without them. Schools wouldn’t and couldn’t run day to day without our educational support colleagues!

How I Teach

What to do when your class loses focus? This teacher picks up a guitar

Joella DeLisi Melnikov

As a teenager in a sea of 4,000 students at Staten Island’s Tottenville High school, Joella DeLisi Melnikov found her niche in the music room.

“In the music room, you knew everybody,” recalls Melnikov, now 36. “There’s really nothing like sitting in the middle of an orchestra or band … and feeling the music and being surrounded by everyone around you.”

At age nine, Melnikov picked up the clarinet, setting off a love of music that led to two separate music degrees and a number of professional gigs. She often taught private lessons on the side to students who complained that there were few public music classes available to them.

That gave Melnikov a sense of mission when she began teaching music in the city’s public schools — a job she landed (part-time at first) through the city’s Arts Matter program, an effort to expand access to arts education.

Now, as a full-time teacher at P.S./I.S. 121 Nelson Rockefeller in Brooklyn, she is hoping to help her students feel connected to school through music, and inspire a few musicians in the process.

This interview has been lightly edited.

One word or short phrase you use to describe your teaching style:

Energetic. I am always excited to try new things and take risks with the kids, and we feed off of each other’s energy and enthusiasm.

Why did you become a teacher?

Learning music in public school changed my life. I wanted to give that same opportunity to other children.

What does your classroom look like?

My classroom is a completely hands-on room, where all of the instruments are laid out all around you. The students are able to pick up whichever instrument they’re currently working on and jump right into a rehearsal. Even the students as young as kindergarten are able to take out the rhythm instruments and share them with the class.

Fill in the blank. I couldn’t teach without my ________.

Smartboard.

Why?

The students are constantly asking to learn new songs or to try out new things. We can quickly pull up anything they are interested in and try it out right away.

What is one of your favorite lessons to teach?

Modern Rock Band. I took the Little Kids Rock workshop, [which helps teachers learn to use music students already listen to], and they introduced the Modern Rock Band curriculum. It is the easiest and quickest way to get students who don’t even know how to hold an instrument to begin playing songs that they recognize and can sing along to. The students sound like a real rock band within just a few lessons.

How do you respond when a student doesn’t understand your lesson?

I first try to understand what it is they’re having trouble with. If I try explaining it a different way and they’re still struggling, I ask one of their classmates to help. They often have a way of explaining things from their own viewpoint that they understand much better from each other.

How do you get your class’s attention if students are talking or off task?

If the whole class needs to be brought back to attention, I’ll pick up a guitar and start playing a song. One or two more students might join in, and the rest of the class will enjoy the short performance. Then I remind them that this is what we’re working toward, and get them back to work. If I just have one or two students having trouble paying attention, I’ll put them in charge of helping another student. They really enjoy taking ownership of their skills and knowledge.

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 try to be very real with my students. They see that I’m a person too, and I make mistakes. We have a motto in our classroom: Respect yourself, each other, and the instruments. I treat them like young adults, and they give me the same respect. They also like to read the inspirational posters we have hanging in the room like: “It’s okay to make a mistake when you’ve tried. It’s a mistake not to try.”

We talk about how it’s inevitable that we’re going to make a mistake, because we’re trying new things. And we may even feel embarrassed now and then. But we’re all in this together. When someone is struggling, I can hear them calling out and quoting that poster to each other. The music room is a safe place for a lot of them. They stop by when they’re having a rough day, and they know they won’t be judged here.

Tell us about a memorable time — good or bad — when contact with a student’s family changed your perspective or approach.

I had a student who had a very different home life from what I had imagined. When he often forgot his instrument and lost his music, I assumed he just wasn’t that interested. I learned that he was often going to a different house each night, and he was doing his best to overcome his own obstacles. I invited him to come rehearse with me during lunch, and gave him a second set of instruments and music to keep at school. He became one of my best musicians that year.

What’s the best advice you ever received?

Tomorrow is another day. Even if everything goes completely wrong, we can try it all again tomorrow. A bad dress rehearsal often precedes an amazing performance.
