【摘要】：电化学是高中化学的重要内容之一,在中学化学体系中,电化学因其独特的逻辑性和在实际生活生产中运用广泛性而占据着重要的学科地位。在电化学的整个发展过程中形成了它特有的学科思维方法和策略体系,在中学化学中电化学因其理论性较强,现如今的人教版高中化学新教材将电化学知识由易到难的编排在化学必修2的第2章第3节化学能与电能和选修4第4章电化学基础。由于电化学部分的强理论性和逻辑性,高中生在学习和习题解答时还存在一些问题,本课题正是立足于中学电化学相关知识这一领域,以建构主义学习理论、问题解决影响因素、自我监控策略、元认知理论等教育心理学理论为指导,采用文献查阅、访谈、问卷调查、实验等方法对高中生电化学问题解决能力进行具体的研究。学生问题解决能力的思维过程,是培养学生科学探究能力的有效途径之一,不仅有利于学生体验科学探究的全过程,还有利于创新学习、终身学习的培养。就中学化学这门学科而言,研究学生电化学问题解决的能力,不仅有利于学生科学的学习化学这门学科,更加有利于帮助教师选择合理有效的教学策略从而达到锻炼学生思维能力的目的;有利于促进电化学原理和概念“整体建构”的教学研究,提高电化学知识的学习质量。首先,本文根据笔者的高中化学辅导和教育实习经历就高中生电化学学习情况、习题解决现状、教师电化学教学情况三个维度编制了调查问卷和设置了访谈提纲,旨在了解高中生学习、复习电化学期间存在的问题,了解高中一线教师在该部分的教学现状和电化学问题解决教学技能技巧,为下一阶段的原因分析提供事实性依据;其次,本文针对前一阶段的调查结果作出了详细的原因分析、总结并据此提出了具体的问题解决策略和教学设计;最后,为了检测问题解决教学策略的有效性,笔者将部分策略运用于中学课堂进行实验,并取得了一定的效果。
[Abstract]:Electrochemistry is one of the important contents of high school chemistry. In middle school chemistry system, electrochemistry occupies an important position because of its unique logic and extensive application in practical production. In the course of the whole development of electrochemistry, it has formed its unique discipline thinking method and strategy system. In middle school chemistry, electrochemistry is more theoretical because of its strong theory. Nowadays, the new textbook of senior high school chemistry in the people's Education Edition arranges the knowledge of electrochemistry from easy to difficult in chapter 2, section 3 of Chemical compulsory course 2, and the basis of Electrochemistry in chapter 4 of electives 4 and 4. Due to the strong theory and logic of the electrochemical part, there are still some problems in the study and problem solving of senior high school students. This topic is based on the field of electrochemical knowledge in middle school to study the theory of constructivism. Under the guidance of educational psychology theories such as problem-solving influencing factors self-monitoring strategies metacognitive theory and so on the paper studies the electrochemical problem-solving ability of senior high school students by means of literature review interviews questionnaires and experiments. The thinking process of students' problem-solving ability is one of the effective ways to cultivate students' scientific inquiry ability. It is not only conducive to the students to experience the whole process of scientific inquiry, but also conducive to the cultivation of innovative learning and lifelong learning. As far as chemistry is concerned, studying students' ability to solve electrochemical problems is not only conducive to the scientific study of chemistry. It is more helpful to help teachers choose reasonable and effective teaching strategies to train students' thinking ability, to promote the teaching research of electrochemical principle and concept "whole construction", and to improve the learning quality of electrochemical knowledge. First of all, according to the author's senior high school chemistry tutoring and educational practice experience, the author compiled a questionnaire and set up an interview outline on the three dimensions of senior high school students' electrochemical learning, problem solving status, teachers' electrochemical teaching situation. The purpose of this paper is to understand the problems existing in senior high school students' study, review the problems existing in the course of electrochemistry, understand the current teaching situation and the teaching skills of electrochemical problem-solving in this part of senior high school teachers, and provide a factual basis for the cause analysis in the next stage. This paper makes a detailed cause analysis of the investigation results of the previous stage, summarizes and puts forward specific problem-solving strategies and teaching design based on them, and finally, in order to test the effectiveness of problem-solving teaching strategies, The author applies some strategies to experiment in middle school classroom, and obtains certain effect.
