CALL FOR PAPERS: COGNITIVE TASK ANALYSIS The Human Systems Center (HSC) currently has several tutor development efforts designed to increase performance on complex cognitive tasks such as aircraft maintenance. The tutors provide a coached environment where the student will ``learn by doing'' in a simulation of the real world environment. The coaching generates domain expert advice based on the actions the student has performed using a knowledge base. A Cognitive Task Analysis (CTA) is performed to gather information prior to building each tutor. The CTA includes the collecting, analyzing and developing the data necessary to build the tutor. The CTA data includes reports to support the problem set, curriculum organization, system model, student model, expert strategies, and coaching strategies in the tutor. The Human Systems Program Office (HSC/YA) is calling for papers on methods of performing a CTA for developing a intelligent tutoring system to teach troubleshooting skills. We are interested in methods to identify deficiencies in system, procedural, and strategic expertise in the field and defining expert behaviors to be taught in the tutor. A specification of the tutoring system is available on the World Wide Web at http://www.brooks.af.mil/HSC/PKA/programs/mst/master.html. Send one (1) copy of paper to: Yolanda Tollinger, HSC/YAK, Bldg 727, Brooks AFB TX 78235-5218, not later than 02 June 96. All papers submitted will be retained by the government. Authors may be invited to brief topics of particular interest to the government. For questions of a technical nature, please contact Christopher Marsh (HSC/YAER) at (210) 536-4528. This notice is not intended to result in the award of a contract nor will the government pay for information solicited or provided.
