Modern technology has a strong influence on many things we do. In fact, technology is shaping almost every part of our daytoday existence, including education. Ashok Goel is a professor at the Georgia Institute of Technology. Every term over 300 graduate students take his class on artificial intelligence (AI). The students never meet in person. All of the classes take place online—through a website.
Having hundreds of students in a class means Ashok Goel has to answer thousands of questions. He has eight teaching assistants to help him. But even that is not enough to give all the students the help they need. So, i n January, he decided to try an experiment. At the start of the spring 2016 semester, he added a new member to his teaching team: Jill Watson. She was able to answer questions faster than most other teaching assistants. And she was available 24 hours a day. It was only at the end of the semester that Goel's students learned Watson's secret: she was not a real person. Jill Watson is an AI computer program. Goel says only two students came close to predicting Watson's true identity. He was worried about telling his students because he thought they would not like being part of the experiment. But once they learned Watson's identity, they became very excited.
“Then, you know what happened? They not only asked that question about Jill，”“Is she an AI? Once the identity of Jill was revealed, they also asked if I was an AI，” he said.
Goel now uses Watson in two classes, but still doesn't tell his students which of his teaching assistants is a computer program. He hopes this technology will make it easier for teachers to create their programs to use in and outside the classroom.
