When word spread this weekend that a massive open online course about online education had to be suspended  due to technology problems that left many students angry, officials from Coursera and the Georgia Institute of Technology were not available for comment. In interviews Monday, however, officials of both Coursera and Georgia Tech confirmed that the major issue concerned the ability of the 41,000 students to discuss topics in small groups, and that the technology for that feature indeed was not working. The officials also said that they were confident that fixes would be made in a short time period, and that the course would then continue.
Richard A. DeMillo, director of Georgia Tech's Center for 21st Century Universities, said that officials were "not seeing any insurmountable problems" with the technology. There wasn't enough time to test the features for group discussions, he said. Asked if such testing should have taken place, DeMillo said that it was important to put the issue in perspective. "In a bricks and mortar course, it would have taken months to identify and make changes." DeMillo said it was important to let instructors experiment. "If we tell people to just do safe things, we'll stifle innovation," he said.
Andrew Ng, a co-founder of Coursera, said that the experiment using Google Docs for small group discussions "didn't work well enough," but was "really innovative." He said Coursera is continuing to work on quality control mechanisms that can be used before course launches. But he added that "I'm proud we let instructors experiment with different formats."
