摘　　要：采用二段式测试与半结构化访谈法对学生关于"盐类水解"内容的学习进行探查,了解学生盐类水解的定义与本质、水解反应方程式的书写、盐溶液的酸碱性的判断、盐类水解的影响因素、盐类水解中3大守恒定律的应用、盐类水解的应用等6个主题的心智模型,包括样例依存模型、概念混淆模型、思维定式模型、宏-微-符认知偏差模型等,并给出了相关的教学建议。This paper probed high school students＇ learning about the content of saline hy drolysis by using the two-tier diagnostic tesls and semi-structured interviews, and comprehend their mental models about definition and nature of saline hydrolysis, writing in hydrolysis reac- tion equation, judging acid-base property of salt solution, influence factors of saline hydrolysis, applying three conservation laws in saline hydrolysis and application of saline hydrolysis, such as interedependency model, misconceptions model, thinking-set model, macro-micro-symbol cognitive bias model and so on. At last, this paper put forward relevant teaching suggestions for teachers.
