Developers and instructors were reacting negatively to the excessive price of developing CAI packages, the inadequate provision for instructor training, and the lack of sources.

Because the pupil works step-by-step by their drawback fixing process, an ITS engages in a course of referred to as mannequin tracing. Communicate the aim construction underlying the problem solving. The goal of most of those authoring tools is to simplify the tutor growth course of, making it potential for people with less experience than professional AI programmers to develop Clever Tutoring Techniques.
