“离子反应”学习困难及成因分析
离子反应作为新课标高中化学学习的重要内容之一,学生在学习的过程中普遍存在着困难。离子反应位于新课标人教版必修1第二章第二节，是高中化学的核心内容，贯穿于高中化学始终，对高一学生而言，受自身知识水平和思维特点的限制，在概念的深入理解和知识迁移等方面都有困难。因此找到学生在学习离子反应时存在的困难，分析总结造成学习困难的根本原因，有利于学生化学知识结构的建立。本论文的研究对象为河津中学高一 555班一个班的学生和高一的3名化学老师，采用文献分析法、问卷调查法、访谈法，对高中化学人教版必修1“离子反应”这一节内容的难点进行分析归纳，归纳总结出学生学习困难形成的原因，最后在理论分析和调查总结的基础上提出相应的建议，为我国教育者研究教材编排和教师授课提供导向。

Analysis on Cause of Difficult Points of Ionic Reaction
Abstract: As one of the important contents of chemistry learning in the high school curriculum, and students have general difficulty in the process of learning. The second part of the second chapter is the core content of high school chemistry has always been, for high school students, by their own knowledge level and thinking characteristics of the concept of In-depth understanding and knowledge transfer and so on. Therefore, it is important to find the students’ difficulties in learning the ion reaction, and summarize the root cause of learning difficulties, which is conducive to the establishment of students' chemical knowledge structure. The research objects of this paper is the students of Hejin Middle School and three chemistry teachers, using literature analysis, questionnaire survey and interview method. The difficulties of this section and the reasons for the formation of students' learning difficulties are summarized. Finally, the corresponding suggestions are put forward on the basis of theoretical analysis and investigation, which will provide guidance for the teaching materials and teachers' teaching.
Keywords: senior high school students, ionic reaction, learning difficulty, analysis of cause of formation in difficulty
