Cognitive tutoring software is continuing to be used. According to a recent "Business Insider Report" article, Ken Koedinger, a professor of human-computer interaction and psychology at Carnegie Mellon University, says teachers can integrate cognitive tutoring software into the classroom. He suggests that teachers use it in a computer lab environment or during classes. In its more current versions, cognitive tutors can understand the many ways that a student might answer a problem, and then assist the student at the exact time that the help is required. Further, the cognitive tutor can customize exercises specific to the student's needs.
