碩士 === 國立師範大學 === 化學學系 === 81 === The purpose of this study was to explore the performance of talented students while solving aqueous euilibrium problems. asked to think aloud while solving problems and their analyzed to describe their problem-solving behaviors and factors affecting success of problem-solving. Three major clusions are summarized as follows: (1)Problem-solving behavior Four subjects'' performance was characterized by the nature cessful problem solvers and novices. The former includedl representation, perceiving the problems as tasks deservings and reasoning,using good heuristics, and constructing a solving conceptualization of domain specific knowledge. (2)Specific concepts and skills for problem-solving of aqueous All subjects can use the related concepts and skills to, but some possessed chemical misconceptions. (3)Factors affecting success of problem-solving The results indicated that those factors affecting success solving included appropriate problem representation,the amount chemical content knowledge, using the algorithm correctly,ma- tical skills, effective strategy,checking of the inconsistecy reasoning and quantitative calculation and the difficulty of
