A bus stop designed to stay cool without an air conditioner. A ferry schedule sent by text message to islands without internet access. A license required before submitting AI-assisted homework. None of these came from a government lab or a startup, but from students working in small groups and presenting across five IVECA Live Classes this semester built around a single prompt: Solving Modern Challenges. Students from China, Indonesia, Korea, and Singapore each examined an issue close to home, connected them to global patterns, and pitched their own solution.
In Korea, where Hanil High School's entire 11th grade took part, students kept circling back to a single tension: the pace of the country’s technological and urban growth is starting to outstrip the systems built to support it. One group traced Jeju Island's traffic jams and overflowing bins back to the convenience of low-cost flights and proposed daily visitor caps alongside eco-friendly travel packages. Another noticed that not every neighborhood was cooling equally as heat waves worsened, and paired satellite thermal imaging with AI to steer green infrastructure toward the hottest, lowest-income neighborhoods first.
In the face of what technology is doing to their own daily lives, the proposals grew sharper. One Korean group proposed taxing the electricity and water consumed by AI data centers and channeling the revenue into youth community hubs. Another, concerned about how easily classmates lean on AI for homework, designed a tiered "AI Competency License" that would grant students different levels of access based on their ability to use AI responsibly.
Students at their partner schools in three very different regions brought their own local perspectives, addressing the same theme in diverse ways. In Indonesia, one group designed “LAUT NUSA, a ferry system built around solar-diesel hybrid vessels small enough to dock at shallow, unpaved shores, with schedules sent by SMS so that communities without internet access could still track the next crossing; another group, worried about how easily misinformation spreads, launched a peer-led "Think Before You Click" campaign to build sharper digital habits and filter the information critically among younger students.
Chinese students leaned into their country’s tradition of organized civic participation, proposing a monthly "Waste-Sorting Day" run by student ambassadors to close the gap between what their neighbors already know about recycling and what they actually do. Another group pointed out that China's environmental clubs and recycling campaigns rarely talk to each other, let alone to groups abroad, and proposed a “Youth Exchange Network” to close that gap.
And in Singapore, where every public structure has to work harder, students reimagined the ordinary bus stop, where their “BioStation” concept harvests the vibration of passing traffic and footsteps to power a cooling green roof, promising shelters that feel five to eight degrees Celsius cooler without a single air conditioner.
After presenting their solutions to modern challenges, students turned to sharing the cultural traditions. Hanil students demonstrated Taekwondo, offering a window into the discipline behind Korea's national martial art. Their partners answered in kind, each performance carrying its own signature: Indonesian students played a Maluku folk song on traditional instruments and shared traditional dishes; Chinese students demonstrated their traditional calligraphy, brush strokes forming characters live on screen; and from Singapore, students performed the Nusantara Dance, rooted in their heritage.
One Indonesian student said the performances allowed her to "see and share the beauty of our cultures," appreciating differences and similarities she had not noticed previously. Her reflection captured an important lesson from the semester: designing a shared future does not require students to leave their cultural identities behind. Instead, understanding one another’s experiences and traditions can deepen the collaboration needed to address common challenges.
Towards the end of the Live Classes, students' reflections revealed how the problem-solving and intercultural exchange had shaped their learning. A student from Indonesia wrote that working in groups to connect local issues to the Sustainable Development Goals helped her understand different perspectives and “realize how important collaboration is in solving real-world problems." A student from Korea put it similarly, saying the exchange made the group feel less like students finishing an assignment and more like "young people genuinely trying to understand the world." At the end, what mattered most was not only the solutions themselves, but also the students’ growing commitment to taking another country’s problem as seriously as their own.
