MOOCs (massive open online courses) are free classes offered by universities hoping to provide the general public with access to top professors. At Emory, MOOC topics have included Introduction to Digital Sound Design and The Addicted Brain. Kennesaw State has a MOOC introducing K-12 teachers to blended classroom and online learning. Georgia Tech offers a range of these high-tech courses, including “Control of Mobile Robots” as well as its new computing master’s degree. Some of the classes in that degree program are open only to enrolled students, but many will be free to anyone with an Internet connection by spring.
