Abstract：

Electronic circuit troubleshooting is one of the most difficult learning unit in studying electronic technology. It needs solid foundation in electronic circuit theory, electronic component characteristics and mastery of troubleshooting instruments. The traditional method of evaluating the troubleshooting performance taken by teachers and trainers was the "Observation Method". But the advantages of objectivity and real-time of computerized test may take place the traditional subjective methods. This paper investigates the feasibility of computerized troubleshooting skill test both in theory and application. Three theories pave the foundation of computerized skill test: Behavioral Decision Theory, Competence-Based Skill Evaluation Theory and Fuzzy-Based Comprehensive Assessment. The Behavioral Decision Theory can be used in the decision-making of troubleshooting. And the Competence- Based Skill Eval-uation Theory can be applied in the construction of weighted item bank. For the theory of Fuzzy-Based Comprehensive Assessment, it can be applied in evaluating the process of troubleshooting. Color TV and microcomputer were taken as typical examples for the discussion of troubleshooting evaluation. It is found that the computerized skill test is feasible in small logic circuit. And it will be applied to the big-ger systems such as televisions and microcomputers if the assessment logic and interface circuits are well designed.
