Universities, too, will have global classes, with students joining lectures, discussion groups, and research teams from a dozen or more universities at a time. This past year, my own university – Columbia University in New York City – teamed up with universities in Ecuador, Nigeria, the United Kingdom, France, Ethiopia, Malaysia, India, Canada, Singapore, and China in a “Global Classroom” that simultaneously connected hundreds of students on more than a dozen campuses in an exciting course on global sustainable development.
