A Quick Comparison of CAI, ITS and Pedagogical Agents Knowing what you know from the course reading so far, how would you describe the differences and similarities between pedagogical agents, intelligent tutoring systems, and intelligent computer assisted instruction? VanLehn distinguishes two major types of technological types of tutoring: Computer-Aided Instruction (CAI) and Intelligent Tutoring System (ITS). The difference between the two is that CAI's offer immediate tutoring feedback (or hints) to the answers provided by students, whereas an ITS provides feedback and guidance along each step of the problem-solving process, or waits until the answers are submitted and then gives feedback for each step (Van Lehn, p 198). If I understand this division correctly, a CAI could be any program on a computer, such as an interactive e-learning module or a computer simulation with prompts, whereas an ITS is AI-based, and because it is more "intelligent" it can offer f...
