[[abstract]] 本研究的目的在探討高三資優學生解決「水溶液中的化學平衡」問題 之解題歷程及行為表現。研究結果獲得以下三項結論：一、解題行為四位 解題者均具有「成功的解題者」之共同特徵，這些特徵包括：正確的化學 表徵、將解題視為一縝密分析及推理的過程、運用有效的捷思法以及運用 相關的原理與概念來解題。二、解題概念與基本技能四位解題者在解題過 程中多能運用相關的概念與基本技能來解題，但是部分解題者對於酸鹼滴 定的當量點與滴定終點的區別、各種滴定曲線的型態以及緩衝溶液等概念 的認知出現迷思概念。三、影響資優學生解題成敗的因素影響解題者解題 成敗的因素有下列幾項： 1.適當的問題表徵。 2.對化學概念與基本技能 的正確理解與完備程度。 3.正確的化學表徵。 4.適當地使用演算法則 。 5.化學的數學知識。 6.有效的解題策略。 7.定性推理與定量計算結 果的交互檢驗。 8.題目的難度。 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 The purpose of this study was to explore the performance of
