Research Topics


Intelligent Tutoring Systems (ITSs) have shown great promise in a variety of training domains and can achieve many of the same benefits as one-on-one instruction, in a cost-effective manner. Our Phase I ITS authoring tool prototype demonstrated an innovative approach to Internet ITS development using a case-based reasoning (CBR) paradigm which largely circumvents the difficult and time-consuming process of knowledge elicitation. The case-based approach to knowledge gathering was shown to be highly intuitive, and authoring of the training course was greatly simplified, requiring no special computer training. Phase I also demonstrated critical Internet communication capabilities to allow the ITSs to be delivered, instruct, cooperate, and send back updated student models, over the Internet. The authoring tool prototype was used to develop and demonstrate a prototype AWACS ITS. In Phase II, we will develop a fully functional Internet ITS Authroing tool, for use by AF personnel to develop Internet ITSs which use a CBR approach to train air crew and others. This tool will be applied to the development of an ITS for training AWACS personnel. The AF will benefit from improved training capabilities, reduced manpower needs and travel costs, better, more efficient training, and increased flexibility.
