When Learning Leaves the Classroom

In Arthur Williams’s eighth-grade Computer Science and Engineering class, learning didn’t stay within four walls this semester. Instead, students took their skills into the community—designing interactive STEM exhibits for Chattanooga’s Creative Discovery Museum.

In his first semester at GPS, Williams set out to help students see how their work could have real-world purpose. Partnering with museum staff, the class took on the challenge of creating “walk-up” exhibits—hands-on learning stations used during busy museum days to engage young visitors.

“The goal was to let the girls still learn everything they needed to learn,” Mr. Williams explains, “but see if there was a way for us to contribute to the museum in a way that was useful and meaningful.”

Students worked directly with museum educators as clients, visiting the space, gathering feedback, and revising their designs through an authentic engineering design process. Over the final weeks of the semester, they applied coding, circuitry, 3D printing, laser cutting, and graphic design skills to bring their ideas to life.

The result was four interactive exhibits, each tied to Tennessee learning standards:

• A color-theory spin art station that explored color mixing theory and motion
• A circuitry challenge using 3D-printed angler fish that lit up when circuits were completed
• A non-Newtonian liquid experience that showed how materials can behave like both solids and liquids
• A magnetism and circuitry activity that challenged visitors to complete a rainbow of lights

While the technical learning was significant, collaboration was equally central. Students worked in groups all semester, learning how to navigate different work styles, communicate effectively, and persevere through challenges. One group, Mr. Williams notes, especially embodied the class’s “fail forward” mindset—reworking major setbacks into a successful final product.

Grades were based on process rather than perfection, reinforcing that learning comes from reflection, iteration, and resilience. “While the grade came from the process, a final product was also important. Without a working final product, they also had to be ready to stand in front of people and explain why something didn’t work,” Mr. Williams says. “That’s part of the learning.”

Museum staff later visited campus to provide professional feedback, giving students insight into how their work was received beyond the classroom.

The exhibits will be showcased during the Middle School Showcase and then donated to the Creative Discovery Museum to extend their impact into the wider community.

For these eighth-graders, the project offered more than technical skills. It showed them what’s possible when learning is purposeful, collaborative, and connected to the world beyond GPS.
