Like many middle school science teachers, I’ve spent more time talking about rocks and minerals than I care to discuss.

As a sixth-grade science teacher at Excellence Girls Charter School, an Uncommon school, earth science was an important part of my work. And throughout my career, I have found ways to make those lessons engaging: One day, students were handed a top-secret mission from NASA to create a planet similar to Earth, requiring them to learn about the interior of our planet, its atmosphere, and the water, carbon, and nitrogen cycles. Another day, the students walked into a classroom filled with fog. They could barely find their desks, and that’s how they learned about cumulus clouds.

Still, I questioned whether those topics were the best use of my students’ time.

It was difficult to give students a real answer about how the curriculum would affect their futures, especially for the ones who might opt to go down a technical track after high school. Not that there aren’t plenty of careers in health and environmental sciences they might choose from, but I wanted to equip them with knowledge that would create tangible career options for every single one of them.

A few years ago, I read an article about a homeless man who learned how to code and got a job at Microsoft without a college degree. I thought, “My students love technology. If he can learn to code and springboard himself into a lucrative career, so can they.” That’s when I started a coding club in my school in North Carolina.

There was one problem: I didn’t know the first thing about how to code.

The night before each club meeting, I would practice lessons on Codeacademy and then teach them to my students. We fell in love with coding together.

Many of the students that hadn’t performed well academically in the past did extremely well in coding club. They also started showing up to my science class fully engaged. They had found a class where they could see a future for themselves. Still, I was troubled that the girls almost seemed to feel out of place.

I started at Excellence Girls Middle Academy one and a half years ago, and yes, I started out teaching rocks and minerals. My principal, a former science teacher, is amazing and loves math and technology. She immediately agreed that we needed a coding enrichment initiative, and I started my coding club there with 20 girls.

The girls in the club were fearless. They exuded confidence that they could do anything and be anyone. Being surrounded by each other, it was a no-brainer to them that women could be programmers.

In my coding brain, this means: < if girls == fearlessness && excellence> < Girls + coding == empowerment >. How could I deny any of my students this opportunity?

At the end of my first year at Excellence Girls, I told my principal I couldn’t teach rocks and minerals anymore, and that I could only stay if we replaced my earth science class with a computer science class.

She agreed. I found a summer fellowship that the Flatiron School was offering in partnership with Teach For America, and since I was a TFA alumnus, I got to learn to code for free. I now have a solid foundation in Ruby on Rails, HTML, and CSS, and I teach 87 girls an introduction to computer science course full time.

My point is not to draw more attention to what I’m doing or to downplay the importance of more traditional subjects.

But I see my coding class as giving students an important opportunity they might not otherwise have: to grow comfortable enough to pursue coding in the future, which could lead to in-demand career options for them and more much-needed diversity in the tech sector.

I’m inspired to see the mayor rolling out the Computer Science For All initiative over the next 10 years, and it’s great to see Teach For America getting involved. But I urge teachers not to wait for the city’s initiatives to reach their schools. You don’t have to be a part of TFA to do this either. Just start a coding club at your school this year.

I know firsthand how unnerving it can be, especially if you don’t have any coding experience. Turn to organizations like ScriptEd, New York on Tech, and the iZone, which provide free lesson plans and tools. If you want your students to be exposed to other people of color in STEM fields, my blog POCIT (People of Color in Tech) provides interviews with people with diverse backgrounds.

It’s possible to turn sixth-grade science class into a place that engages students now, and helps them engage with their futures.
