A STEM Teacher Explains What Happens When You Use Video Games in Class
The first time I brought Minecraft into my sixth-grade STEM classroom, I expected chaos. Instead, I got a scene I didn’t fully understand until later: Marcus, a kid who usually stared at the clock during fractions, was hunched over a laptop, adjusting a line of redstone dust. “If I put the repeater here,” he muttered, “then the door should close faster.” His partner, Amina, was sketching a circuit diagram on scrap paper. Neither noticed when I leaned in to look.
We were supposed to be learning about basic electrical circuits. I’d spent the previous weekend searching for ways to make it less abstract, and I’d found a bunch of other STEM teachers posting about using Redstone in Minecraft as a stand-in for real circuits. So I borrowed a lab set of school laptops, loaded the education edition, and gave up my traditional lesson plan for two days. I was nervous. Our principal had not exactly encouraged “screen time” as a core teaching method. But I figured it was worth a try.
What I learned over the next few weeks changed how I think about teaching, but not in the way you might expect. It wasn’t that the video game magically made everything fun. It was that the game gave the kids something to argue about—in a good way. When Marcus and Amina couldn’t get their door to open, they didn’t raise their hands and ask for the answer. They tried different placements, talked through what each component did, and made mistakes that they actually cared about fixing. That’s the part I hadn’t planned for.
The thing about video games in STEM is that they are terrible at teaching core concepts by themselves. A kid can play Minecraft for a hundred hours and still not understand why real circuits need a load or why batteries have polarity. The game is not the lesson. It’s more like a shared problem-solving space. As a teacher, my job is to build the bridge between the game and the science. So after the Redstone activity, I sat the class down and asked: “What happened when you increased the length of the wire? Why did the torch flicker? What would happen if we used copper wire instead?” The game didn’t answer those questions. The discussion did. And because they had built something themselves, they actually wanted to know the reasons behind the rules.
That’s the practical side that a lot of parenting articles miss. It’s not about handing kids a tablet and hoping they learn physics. It’s about using the game as a kind of shared reference point. When a student says, “Oh, it’s like in Kerbal Space Program when you don’t have enough thrust,” I can then say, “Right—so what does that tell us about Newton’s second law?” The game gives us a common language. For kids who struggle with abstract formulas, that’s huge.
I’m not a tech evangelist. I’m a teacher who is tired of seeing kids tune out when I draw a force diagram on the whiteboard. But I’ve noticed some specific things that happen when I use games, and I think they’re worth sharing with parents and other teachers.
First, the engagement is not constant or magical. Some kids love the game; some just tolerate it; a few would rather do paper worksheets. The key is to make the game optional in terms of how they access the problem, not the goal. For example, when we did a unit on planetary orbits, I set up a station where kids could mess around with Kerbal Space Program, but they still had to 3D-print orbit diagrams and write a short explanation of elliptical paths. The game was a means, not the reward.
Second, you have to be okay with a messy classroom. Video games are loud. There are moments when kids shout “No, not there!” and someone else says, “Try it again, but slower.” It can feel like a playground, not a classroom. But that noise is a sign that they are working through something. The real discipline is teaching kids to talk about the game in terms of the underlying science. I use sentence starters on the board: “I noticed that…”, “What if we tried…”, “That didn’t work because…” It sounds simple, but it gives them a way to turn gaming action into scientific reasoning.
Third, I now buy my own headphones. The cheap school ones break easily, but that’s another lesson in itself. I keep a bin of five-dollar wired earphones, and kids know that if they want to play a tutorial video or listen to the game’s sounds, they need to bring their own or use the ones I’ve taped with their names. It sounds like an administrative detail, but it actually solves half the classroom management problems. The other half is having a clear “stop and drop” rule: when the timer goes off, they save and quit. No exceptions. That might sound strict, but the kids actually like the boundary. It makes the gaming time feel intentional, not chaotic.
The most surprising thing, honestly, has been how the games changed the roles of different kids in the classroom. I have a quiet girl named Rosa who never raises her hand in math. But in Stardew Valley, when we used the farming calendar to talk about crop cycles and data tracking, she was the one who spotted the pattern of harvest times. She wasn’t talking about the game itself. She was talking about the spreadsheet she’d made. I’m not saying video games are a magic cure for shy kids, but I think they offer a different kind of structure. In a normal lesson, there’s one right answer and it’s usually me who knows it. In a game, there are multiple solutions and the kids are the experts. That flips the power dynamic, and sometimes that’s enough to let a different voice surface.
I’ve also had to answer some tough questions from parents. One mom emailed me after her son came home asking if he could install Steam on the family computer. She was worried that I was just turning school into playtime. I wrote back with a simple explanation: we use games as a simulation tool, but we still do the math. I attached the rubric for the orbit project, which asked for calculations and a written reflection. She wrote back, “Okay, that makes sense.” That email is a good reminder that most parents aren’t against games; they’re afraid that games mean the learning is fake. My job is to show them the work that surrounds the game.
I still don’t know if I’m doing this right. Some weeks, the game-based lesson falls flat. Yesterday, we tried to use Portal to talk about problem-solving and spatial reasoning, and half the kids were just frustrated by the controls. We abandoned it after twenty minutes and went back to graph paper. That’s fine. There’s no perfect method. What I’ve learned is that video games are just another tool in the box—not a magic one. They work better when I have clear learning goals, when I build in time for discussion, and when I let go of the idea that every minute has to be productive.
I’m glad I tried it. The Redstone lesson didn’t turn my classroom into a futuristic lab. It turned it into a place where a kid who was sure he was “bad at school” explained to me how to make a logical gate work. I still had to quiz him on current and resistance the next day. He still got three questions wrong. But he didn’t shut down when I handed back his quiz. He said, “Oh, that’s because the resistor was in the wrong place, right?” And I said, “Yes, exactly.” That’s not a perfect story. It’s just a real one. And I’ll take it.
