Cost effective use of artificial intelligence (AI) in training systems depends on teamwork between the instructor and the intelligent device. While AI-based systems are exceptional at providing detailed feedback within narrowly defined tasks, human instructors are exceptional at dealing with trainees misunderstandings of the task and its scope and at motivating trainees. Research and development of an intelligent instructional system, the Intelligent Conduct of Fire Trainer (INCOFT) demonstrates that an AI system can provide a powerful tool to assist instructors in producing proficient graduates.
