At HTS, we often say that the best way to understand the future is to build it. But in our TEJ2O (Computer Technology) course, we take that a step further: before we build the future, we have to take the present apart.
The energy in the TEJ2O lab is less like a traditional classroom and more like a high-tech workshop. It’s a space defined by the sound of screwdrivers, the glow of newly programmed LEDs, and the "A-ha!" moments that only happen when a student moves from a screen to a physical prototype.
The journey often begins with a simple question: “How does that actually work?” Instead of reading a manual, students dive into "tech surgery." They take apart everyday devices, from old gaming consoles to household appliances, to map out their "guts." There is a genuine thrill in this forensic discovery. Students move from being passive users of technology to "hardware investigators," identifying circuit boards, tracing power flows, and debating the "Right to Repair." It turns a black box of mystery into a visible system of logic.
One of the most "fun" parts of the course is the transition from the virtual to the physical. Before students wire up a real-world device, they play in a digital sandbox. Using sophisticated simulation tools, they build "Digital Twins" of their ideas. Want to see if a custom pedestrian crossing or a light-up gadget will work? They build and code it virtually first. This experimental phase allows students to take massive creative risks, if the virtual circuit "pops," they just hit reset and try again. Once the logic is sound, they bring it to life on a physical breadboard, bridging the gap between a line of code and a blinking light.
Technology at HTS isn't just about wires and code; it's about people. We challenge our students to look at the world through the lens of Empathy. Whether they are interviewing peers to redesign the "perfect" school bag or brainstorming ways to make guest Wi-Fi access more seamless for a visitor, they are practicing the first and most vital step of the Engineering Design Process (EDP): Understanding the Human Need. By the time they reach the prototyping phase, using our 3D printers, laser cutters and vinyl tools, they aren’t just making "stuff"; they are solving problems they’ve identified themselves.
There is a specific kind of magic that happens in our fabrication lab. Students learn that with the right design, you can make a rigid piece of wood bend like a "flexible noodle" or turn a flat sheet of acrylic into a complex 3D housing. This "Learning by Doing" approach turns abstract concepts like kerf bending or vector-based design into tangible skills they can see, touch, and take home.
While the projects change year over year to keep pace with the rapidly evolving tech landscape, the core mission of TEJ2O remains the same: to foster a diagnostic eye, an empathetic heart, and a maker’s hands. Whether our students go on to be professional engineers, digital artists, or ethical AI researchers, they leave the course with a superpower: the confidence to look at a complex problem and say, "I can figure out how that works, and I can make it better."
