Mr. Regier sees things evolving fairly rapidly, accelerated by the increasing use of social networking technology. More and more, students will help and teach each other, he said. For example, it will be assumed that college students know the basics of calculus, and the classroom time will focus on applying the math to real-world problems — perhaps in exploring the physics of climate change or modeling trends in stock prices, he said. “The technology will be used to create learning communities among students in new ways,” Mr. Regier said. “People are correct when they say online education will take things out the classroom. But they are wrong, I think, when they assume it will make learning an independent, personal activity. Learning has to occur in a community.”
