Students learn concepts and skills more quickly when they receive one-on-one instruction. Stottler Henke develops intelligent tutoring systems that provide the benefits of one-on-one training -- automatically and cost-effectively. These systems encode the subject matter and teaching expertise of experienced instructors, using artificial intelligence (AI) software technologies and cognitive psychology models. We have developed numerous systems that provide practice-based learning for K-12 education, corporate training and professional development, and military training. For additional information, read Intelligent Tutoring Systems: The What and the How, Intelligent Tutoring Systems Technologies for Military Training, or the Powerpoint presentation: Intelligent Training Systems.

Inflexibility of these expert systems in applying rules, and the tunnel vision implied in their limited knowledge, that can result in poor conclusions. Expert systems couldn't reverse their logical conclusions if later given contradictory facts. For example, an expert system would conclude that Bill Smith has ten toes because Bill Smith is a person and all people have ten toes. However, it couldn't then deal with the fact that Bill Smith lost three toes in an industrial accident. A human, using "non-monotonic" reasoning, has no problem concluding Bill Smith has only seven toes.
