Massive open online courses (MOOCs) may not yet be driving down tuition, but they’re starting to kill the traditional lecture class, reports InformationWeek. At Duke University, professors who teach MOOCs tend to go back and do a radical revision of their on-campus classes. “That’s true for at least half the faculty who developed MOOC classes,” said Lynne M. O’Brien, Duke’s associate vice provost for digital and online education initiatives. She said this was no surprise: MOOCs free professors from constraints required by for-credit classes, like length and format. “People are free to innovate in ways you can’t do with a typical course,” she said.
