ANS:C - Intelligent Tutoring Systems

An intelligent tutoring system (ITS) is a computer system that aims to provide immediate and customized instruction or feedback to learners, [1] usually without intervention from a human teacher. ITSs have the common goal of enabling learning in a meaningful and effective manner by using a variety of computing technologies. There are many examples of ITSs being used in both formal education and professional settings in which they have demonstrated their capabilities and limitations. There is a close relationship between intelligent tutoring, cognitive learning theories and design; and there is ongoing research to improve the effectiveness of ITS.
