How 'Intelligent' Tutors Could Transform Teaching

Schools may be critiqued as "factories," but robots aren't going to replace human teachers any time soon. Still, that doesn't mean that artificially intelligent systems won't transform education just as they are changing a variety of fields and practices, from the way oncologists diagnose cancer to how lawyers analyze cases. Intelligent-tutoring systems like ALEKS (for Assessment and LEarning in Knowledge Spaces), Cognitive Tutor, and a new program in development by IBM's Watson initiative are starting to expand in K-12 education, and experts argue that teachers need new training not only to use intelligent systems in the classroom but also to prepare students for careers in increasingly technology-integrated fields. "Any skill that a computer can teach is going to be done by a computer in the workplace, and that's something people don't think about enough," said Christopher Dede, an education and technology professor at the Harvard Graduate School of Education. For that reason, he said, teachers can use computer programs not simply to replace pieces of their instruction, but to model for students how to work with technology professionally.
