August 4, 2003. CNN International aired the first English-language television story about Wikipedia. The correspondent, Kristie Lu Stout, interviewed me and my students at the University of Hong Kong about a classroom experiment that felt, at the time, either brilliant or completely insane.
The assignment: students would write Wikipedia articles as coursework.
What We Did
The idea was simple. Instead of writing papers only I would read, students would write for the world. They’d contribute to Wikipedia’s growing collection of articles about Hong Kong — its transit system, its neighborhoods, its culture.
The results exceeded expectations:
- Real stakes create real work. Knowing their writing would be read by thousands made students more careful, more thorough, and more invested.
- The feedback loop. Wikipedia’s community reviewed their work, offered suggestions, and sometimes challenged their claims. Students learned to defend their sources and engage with constructive criticism.
- Enthusiasm was contagious. Once a critical mass of content appeared, students started building on each other’s work. Momentum took over.
What’s Changed
Twenty years later, Wikipedia-based education is mainstream. The Wiki Education Foundation has supported over 100,000 students who have contributed 80+ million words to Wikipedia. Courses span disciplines from chemistry to art history, from political science to gender studies.
The infrastructure has improved dramatically:
- Training modules teach students Wikipedia policies and editing skills
- Dashboard tools track contributions and measure impact
- Assignment design templates help instructors structure meaningful projects
What Hasn’t Changed
The core insight remains the same: writing for a real audience transforms learning.
Students who write Wikipedia articles learn:
- How to evaluate sources and distinguish reliable information
- How to synthesize multiple perspectives into neutral, encyclopedic prose
- How to receive and respond to feedback from strangers
- How knowledge is constructed, contested, and maintained
These are exactly the skills every citizen needs in an information environment dominated by AI-generated content, algorithmic feeds, and viral misinformation.
The Next Frontier
Today I’m thinking about what Wikipedia-based education looks like in the age of AI. Can large language models help students generate first drafts? Absolutely — but the real learning happens in the verification, the sourcing, the revision.
The technology may change, but the pedagogical value of contributing to the sum of all human knowledge? That’s timeless.
