Integration of Basic Skills into Vocational Education: Expert Systems in Electronics Technology. Vocational Education Research.

A student who plans to enter the field of technology education must be especially motivated to incorporate computer technology into the theories of learning. Evaluation prior to the learning process establishes a frame of reference for students. After preparing students with the basic concepts of resistors and the mental tools, the expert system should be introduced. Specifically, expert systems are computer programs that encode the knowledge of an expert and replay this information to the novice. An emerging area of expert systems is in education. Building expert systems in education consists of five interdependent activities: identification, conceptualization, formalization, implementation, and testing. Expert systems contain the knowledge of a well defined but narrow field. Integrating basic skills in technology education, specifically, component identification in electronics technology, fits the criterion for expert systems. An expert system works by asking an end-user a number of questions to help pinpoint a problem by narrowing down the answers. These questions are created by an expert in the specific field of resistor identification. In one project, the expert system has been developed on MicroExpert, an expert system shell produced by McGraw Hill. (Appendixes include 13 references, listing of the expert system, and reproductions of actual screens on the computer when the MicroExpert program is executed.) (YLB)
