【摘要】：化学语言是对国际上统一的,具有化学学科强烈特色的化学专用术语的统称。化学语言具有精炼贴切的概括性和严谨的专业性,是学习化学、认识化学、了解化学时不可缺少的认知工具和载体,是科学研究者进行交流的最准确的科学语言。对初中学生的语言启蒙也有十分重要影响。本文的主要研究内容分为以下几点:一是查阅各类文献,寻找研究"化学语言""相关课题的意义和必要性,并在导师的帮助下确定课题,提出需研究的问题。并简明介绍研究该课题所涉及的理论基础和概念界定。二是利用自制测试卷及调查问卷对延边地区部分初三学生进行调查,意在研究学生对化学语言学习的现状,并做详细分析,发现延边地区初三学生对"化学语言"的学习现状良好,单也存在以下几点问题:1.对文字语言的认识不深刻、不严谨;2.对符号语言的记忆不完善,对元素符号、离子符号等内容的混淆现象严重;3.对图式语言中的细节内容把握不全面,理解不深刻。并从学生的学、教师的教、学习内容三个角度出发寻找问题成因并分析。三是针对以上所发现的问题提出应该循序渐进地学习、规范性学习等教学建议,并以"氢气还原氧化铜"及"金属的化学性质"为例,设计两节课的教学案例。最后得出本文的结论,认为化学语言的学习是化学学习的一大重点,学生对化学语言掌握不准确的现象应该由教师转变课堂思路以规范性的化学语言循序渐进地进行。并对研究的前景进行了展望。
[Abstract]:Chemical language is a generic term for chemical terms that are internationally unified and have strong chemical characteristics.Chemical language is an indispensable cognitive tool and carrier for learning chemistry, knowing chemistry and understanding chemistry. It is the most accurate scientific language for scientific researchers to communicate.It also has a very important influence on the language enlightenment of junior middle school students.The main research contents of this paper are as follows: first, consult all kinds of literature, find out the significance and necessity of studying "Chemical language", and determine the subject with the help of tutor, and put forward the problems to be studied.It also briefly introduces the theoretical basis and conceptual definition involved in the study.The second is to investigate some junior high school students in Yanbian area by using self-made test paper and questionnaire, in order to study the current situation of students' study of chemical language, and make a detailed analysis.It is found that the junior high school students in Yanbian area have a good present situation of studying chemical language, and there are also the following problems: 1: 1.The understanding of the language is not profound, not rigorous.The memory of symbolic language is not perfect, and the confusion of element symbol and ion symbol is serious.The details of the schematic language are not fully understood and understood.And from the student's study, the teacher's teaching, the study content three angles starts to look for the question origin and the analysis.The third is to put forward some teaching suggestions such as learning step by step, normative learning and taking "hydrogen reduction of copper oxide" and "chemical properties of metal" as examples to design teaching cases of two courses.Finally, the conclusion is drawn that the study of chemical language is one of the key points of chemistry learning, and that the phenomenon of students' inaccuracy in mastering chemical language should be carried out step by step by teachers' transformation of classroom thinking and standard chemical language.The prospect of the research is also prospected.
