What Happened When 37 Educators Put Problem-Based Learning to the Test

"That level of cognition puts you in competition with TikTok. That's a win." — Carrie Romero-Brugger, PBL facilitator, Grand Junction training

In May 2026, MindSpark facilitated a Problem-Based Learning and STEM experience at District 51’s Summer Institute in Grand Junction, where 37 educators and administrators explored how AI can deepen inquiry, strengthen student engagement, and make learning more locally relevant.

Most professional development follows a familiar script: educators gather, slides advance, information flows in one direction. This program rewrote that script. Participants weren’t passive recipients of ideas; they engaged as active problem-solvers, testing concepts, building understanding in real time, and experiencing learning the way their students do.

The anchor problem was zebra mussel infestations spreading through Western Colorado waterways—a real, costly, and ecologically damaging invasive species issue. What initially looked like a narrow environmental case quickly expanded into a complex system of interconnected topics: ecology, hydrology, city infrastructure, agricultural water rights, and data science.

Rather than receiving solutions, educators stepped into the role of problem-solvers. They questioned assumptions, tested ideas, and experienced firsthand what it feels like to learn through authentic inquiry.

Working in groups, they then mapped the careers connected to that single challenge. Across cohorts, they identified 12+ career pathways per classroom: ecologists, hydrologists, engineers, microbiologists, parks and wildlife officers, data analysts, aquatic biologists, farmers, city planners, and more, all emerging from one well-framed local problem.

That’s not a career fair. It’s what happens when learning starts with something real.

And we know it worked, because they measured it.

During PBL activities, educators monitored their own cognitive shifts in real time, noting when they moved between problem-solving and 21st-century skills like collaboration, systems thinking, and communication. On average, they were switching 2.4 times per minute. A mental gear change every 30 seconds.

When a facilitator noted that level of engagement puts PBL in competition with TikTok, the room laughed, and then got quiet. Not because TikTok is the benchmark. But because that kind of sustained, active cognition is exactly what we're trying to create for students, and most of us rarely stop to measure whether we're actually achieving it. 

As D51 has rural schools and limited time, a thought partner to support grade-level teams and STEM coaches in building STEM PBL units is essential. AI was woven throughout the day in the same spirit, not as a standalone topic, but as a tool embedded in the work. Educators explored prompting strategies, used AI as a planning thought partner, and experienced a hyperlocal interactive learning tool built around the zebra mussel challenge facing Western Colorado waterways. The experience incorporated concepts such as exponential growth, Colorado Parks and Wildlife stewardship messaging, and the role of outdoor recreation in preventing the spread of invasive species, demonstrating how AI can help transform local issues into engaging, standards-aligned learning experiences.

Then they built their own. In under 30 minutes, teachers used vibe coding tools to prototype interactive learning experiences rooted in their own communities. Real outputs that are usable in classrooms, built by people who had never written a line of code.

The through line was the same as the zebra mussel problem: make it local, make it real, and watch what people are capable of.

At the end of the day, educators were asked to put their "why" into words. No prompts or multiple choice. Just what they believed, after a day of living it.

"We do PBL to engage kids in learning and building their identities as problem solvers, advocates, and people who enact change in the world."

"We do PBL so that kids use their brains and fuel their hearts."

"We do PBL because it offers students opportunities to show strength in many different areas and to develop important life skills."

That kind of clarity doesn't come from a slide deck, it comes from experience. From being the learner, not just the teacher of the thing. When educators experience PBL themselves, they don't just understand it better. They own it. And that ownership is exactly what carries back into classrooms, into lesson plans, and eventually into the students who need it most.

When educators experience the power of authentic learning for themselves, they don't just bring back new strategies, they bring back a new vision of what's possible for every student they teach.
