化学习题在整个化学教学过程中占据很重要的地位，特别是高三复习阶段，化学习题是链接老师和学生的重要桥梁，习题能够帮助学生回忆旧知，掌握新知，在习题的解决过程中，形成化学思维模型、提升解决化学问题的能力。习题的完成情况能够体现学生复习的情况，暴露学生的问题，让老师及时的调整教学计划，改进和完善自己的教学目标以达到更加理想的复习效果。在高考重点升学率的压力下，在老师繁重的工作任务中，往往是采用征订的一轮复习资料进行地毯式的复习，征订的复习资料配套习题往往是剪刀加浆糊的结果，习题范围一般就是今两年的高考试题或者地区优质模拟试题，且难度都比较高，题型局限在选择题和填空题，学生一是兴趣不足，二是能力不够，很难消化所有习题达到内化成自身能力的目的。一刀切的习题模式也不能让所有的学生都得到一定程度上的发展，导致班级分化现象明显，带有厌学情绪的学生数量增加。 “一体四层四翼”的高考评价体系立足“立德树人、服务选才、引导教学”的核心目标，强调了对基础性和必备知识的考查，老师应该关注现行教材课后习题的使用情况，关注教科书后习题在高考试题中的显性或隐性体现，深入体会习题的编写意图，想办法深入研究课后习题的使用，驾驭好教科书上的内容。 电化学内容是氧化还原反应的延伸，又能够很好的渗透电化学知识在生产、生活实践中的应用。当下高考试题注重对学生关键能力的考查，电化学能够提供很好的新情境和新背景来考查学生在陌生模型和陌生情境中应用分析解决问题的能力。因此本文开展了对电化学复习同步习题的研究。 在研究中，首先阅读关于习题研究的相关文献，学习习题编制的理论和原则。然后通过对近几年高考试题中电化学的考查分析，总结电化学考点。通过对中美主流高中教科书电化学部分课后习题的对比研究，深刻体会习题的编制原则。通过对典型教辅资料的对比分析，总结当下一轮教辅资料的优缺点。通过对学生使用和选择教辅资料的情况调查总结学生对资料的期待。通过对学生解决电化学能力和障碍的调查和前测，总结学生解决电化学问题的具体障碍和知识方法漏洞。综合之前的对比分析和对高中化学课程标准、化学考试大纲的分析，根据习题编制原则，结合教学实践，关注核心素养的落实，对电化学复习一课一练的习题进行编制与实践研究。 最后，针对本研究中存在的不足和局限性进行了反思和总结，并对有效性习题的编制提出了建议和展望。

Chemistry exercises play an important role in the whole process of chemistry teaching, especially in the review stage of Senior Three. Chemistry exercises are an important bridge linking teachers and students. They can help students recall old knowledge, master new knowledge, form chemical thinking model and improve their ability to solve chemical problems in the process of solving exercises. The completion of exercises can reflect students'review situation, expose students' problems, let teachers timely adjust the teaching plan, improve and improve their teaching objectives in order to achieve a more ideal review effect. Under the pressure of the key enrollment rate in the college entrance examination, the carpet review is often carried out by means of the revised materials in the heavy work tasks of teachers. The matching exercises of the revised materials are often the result of scissors and paste. The range of exercises is generally the college entrance examination questions in the past two years or the high-quality simulation tests in the regions, and the difficulty is relatively high. The types of exercises are limited to the choice and filling-in questions. Students are lack of interest and ability. It is difficult for them to digest all exercises to internalize into their own abilities. One-size-fits-all exercise model can not allow all students to develop to a certain extent, resulting in obvious class differentiation and an increase in the number of students with learning-weariness. The evaluation system of college entrance examination is based on the core goal of "cultivating people by virtue, selecting talents by service and guiding teaching", and emphasizes the examination of basic and necessary knowledge. Teachers should pay attention to the use of after-class exercises in current textbooks, pay attention to the explicit or implicit manifestation of after-class exercises in college entrance examination questions, thoroughly understand the intention of writing exercises, and find ways to study the use of after-class exercises and control the content of textbooks. The content of electrochemistry is the extension of redox principle, and it can penetrate the application of electrochemistry knowledge in production and life practice. At present, college entrance examination questions focus on the examination of students'key abilities. Electrochemistry can provide a good new situation and background to test students' ability to apply analysis and solve problems in unfamiliar models and situations. Therefore, this paper has carried out the research on synchronous exercises of electrochemical review. In the study, first read the relevant literature on exercise research, learning the theory and principles of exercise preparation. Then, the electrochemical test points are summarized through the electrochemical examination and analysis of the college entrance examination questions in recent years. Through the comparative study of the after-school exercises of electrochemistry in the mainstream high school textbooks of China and the United States, the author deeply understands the principles of the preparation of exercises. Through the comparative study of the after-school exercises of electrochemistry in the mainstream high school textbooks of China and the United States, the author deeply understands the principles of the preparation of exercises. Through the comparative analysis of typical teaching and auxiliary materials, we sum up the advantages and disadvantages of the current supplementary teaching materials. Through the survey of students' use and selection of supplementary information, students' expectation of information is summarized. By investigating and forecasting the students'ability and obstacles to solve electrochemistry problems, this paper summarizes the specific obstacles and loopholes of knowledge and methods for students to solve electrochemistry problems. According to the principles of exercise compilation, combining with teaching practice, focusing on the implementation of core literacy, we compiled and practised the exercises of "one lesson, one practice" of electrochemistry review, synthesizing the previous comparative analysis and the analysis of high school chemistry curriculum standards and chemistry examination syllabus. In the end, the shortcomings and limitations of this study are reflected and summarized, and suggestions and prospects for the preparation of effective exercises are put forward.
