Luyao Huang spent 85 meetings watching students wrestle with big problems — not to judge them, but to learn from them. At Leiden University, she sat quietly in classrooms, hallways, and late-night Zoom calls, observing how teams of undergraduates and master’s students from different fields worked together on sustainability challenges. Her goal? To uncover what really happens when biology meets sociology, or economics collides with ethics — and what teachers can do to help.

Complex global issues like climate change or public health don’t fit neatly into one subject. That’s why schools are increasingly turning to interdisciplinary education, where students from different majors team up to find solutions. But just putting smart students in a room doesn’t guarantee success. Huang’s research shows that real collaboration is messy, nonlinear, and full of surprises.

Over months, she followed seven student teams — two from Leiden University College, two from the Leiden Leadership Programme, and three from the LDE Sustainability Honours Programme. She noticed that groups often started strong, dividing tasks and racing toward answers. But when real-world feedback came in — from community stakeholders or new data — their plans wobbled. Assumptions cracked. Some teams even had to restart.

One group thought they were designing a clean water solution for a rural area — until conversations with locals revealed the real issue was access, not purity. Their entire project shifted. This kind of pivot isn’t failure; it’s learning. But it only works if teams keep talking, questioning, and weaving their ideas into shared understanding.

Huang offers three clear lessons for educators. First: give structure. One program used the Double Diamond Model — a step-by-step framework for problem-solving — which helped teams regroup when lost. Second: integration doesn’t happen by itself. Teachers must explain how to blend different perspectives, not just assign group work. Third: check in early and often. Regular guidance keeps teams aligned and prevents frustration.

Her findings will feed into the upcoming Leiden University Guide to Transdisciplinary Education (2025), co-developed by LLInC and the Honours Academy. For teachers aiming to prepare students for real-world challenges, Huang’s message is clear: collaboration isn’t automatic — but with the right support, it can become a powerful tool for innovation.
