【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。更多还原

【Abstract】 The chemical language is a general term for chemical terminology that is unified internationally and has a strong characteristic of chemistry.Chemical language is refined and concise and rigorous professional,is the learning chemistry,understanding of chemistry,understanding of chemistry indispensable cognitive tools and carriers,scientific researchers to communicate the most accurate scientific language.The language enlightenment of junior high school students also have a very important impact.The main contents of this paper are divided into the following points:First,access to all kinds of literature,looking for "chemical language" related topics and the need for the necessity,and with the help of the mentor to determine the subject,put forward the need to study the problem.And a brief introduction to the study of the subject involved in the theoretical basis and conceptual definition.The second is to use the self-made test volume and questionnaire to investigate some students in Yanbian area.It is intended to study the current situation of students’ learning of chemistry language and to make a detailed analysis.It is found that the students in Yanbian area have good learning status in chemistry language,There are the following problems:1.The understanding of the language of writing is not profound,not rigorous;2.The memory of the symbolic language is imperfect,the elements of symbols,ion symbols and other content of the phenomenon of confusion;The details of the language content is not comprehensive grasp,not deep understanding.And from the students’ learning,teachers teaching,learning content from the three angles to find the cause of the problem and analysis.Thirdly,we should put forward the teaching suggestions of two classes according to the suggestions of "hydrogen reduction of copper oxide" and"chemical properties of metal" as an example.Finally,the conclusion of this paper is that the study of chemical language is a major focus of chemistry learning.Students’ inaccurate phenomenon of chemical language should be carried out by teachers in order to change the classroom ideas in a standardized chemical language.And the prospect of the research is forecast.更多还原
