In most online learning, instructors face challenges in achieving similar levels of effectiveness and retention to their on-campus offerings. With so many students to account for an the inability to meet in person, it’s important to find ways to supplement the interaction between teacher and student. As an instructor for a course in Georgia Tech’s Online Master of Science in Computer Science program, School of Interactive Computing Professor Ashok Goel introduced the world to Jill Watson, a virtual teaching assistant who was so good in her first semester on the job that even students thought she was human. Can AIs like Jill really improve course effectiveness and satisfaction? Will they be used to augment the production of the human assistant, not replace it? And can this method, which has proven successful in an academic setting, be used as a foundation upon which other sectors of the workforce can build?
