本文選題：化學語言 + 學習現狀　； 參考：《延邊大學》2017年碩士論文

【摘要】：化學語言是對國際上統一的,具有化學學科強烈特色的化學專用術語的統稱。化學語言具有精煉貼切的概括性和嚴謹的專業(yè)性,是學習化學、認識化學、了解化學時不可缺少的認知工具和載體,是科學研究者進行交流的最準確的科學語言。對初中學生的語言啟蒙也有十分重要影響。本文的主要研究內容分為以下幾點:一是查閱各類文獻,尋找研究"化學語言""相關課題的意義和必要性,并在導師的幫助下確定課題,提出需研究的問題。并簡明介紹研究該課題所涉及的理論基礎和概念界定。二是利用自制測試卷及調查問卷對延邊地區(qū)部分初三學生進行調查,意在研究學生對化學語言學習的現狀,并做詳細分析,發(fā)現延邊地區(qū)初三學生對"化學語言"的學習現狀良好,單也存在以下幾點問題:1.對文字語言的認識不深刻、不嚴謹;2.對符號語言的記憶不完善,對元素符號、離子符號等內容的混淆現象嚴重;3.對圖式語言中的細節(jié)內容把握不全面,理解不深刻。并從學生的學、教師的教、學習內容三個角度出發(fā)尋找問題成因并分析。三是針對以上所發(fā)現的問題提出應該循序漸進地學習、規(guī)范性學習等教學建議,并以"氫氣還原氧化銅"及"金屬的化學性質"為例,設計兩節(jié)課的教學案例。最后得出本文的結論,認為化學語言的學習是化學學習的一大重點,學生對化學語言掌握不準確的現象應該由教師轉變課堂思路以規(guī)范性的化學語言循序漸進地進行。并對研究的前景進行了展望。
[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.
