A Comparative Study Of The Technical Education Contents In The Three Editions Of New Compulsory Chemistry Textbooks For Senior Middle Schools

Today’s international world has entered a new era of scientific and technological revolution.Technology is leading the development of modern human social life and is constantly entering all aspects of human social life.The implementation of technical education affects the improvement of the country’s comprehensive national strength,enabling individuals to face the complex technological world more scientifically,rationally and confidently.Therefore,the research on the content of technical education in textbooks is of great significance.This thesis selects the new compulsory high school chemistry textbooks of People’s Education Edition,Jiangsu Education Edition and Luke Edition as the research objects,and compares the technical education content among them.Taking content analysis as the main research method,on the basis of comprehensive analysis of domestic and foreign documents,the research tools needed by this research are first clarified,and after determining the evaluation index and compiling the coding analysis table,the analysis of the technical education content is constructed model.Secondly,it carries out quantitative and qualitative comparative analysis from the three aspects of content selection,content presentation and content layout.Again,take the related content of "nitrogen" and "sulfur" as an example for specific comparison.Finally,take the "nitrogen cycle" as an example to analyze the chemical teaching strategy of technical education.After comparative research,this article draws the following conclusions:The content of technical education in the People’s Education Edition is unevenly distributed.The content of technical knowledge is the most,and the technical field is relatively conservative and traditional;it occupies a small space and mostly appears in the column in the form of plain text;the content of technical education is interspersed in the subject knowledge,Dispersed distributed,in accordance with the layout:chemical substance and technology-chemical reaction and technology-organic synthesis technology-chemistry,technology,resources.The Luke version contains more ontological technical knowledge and technical value rational content;most of them are distributed in the main text and columns,and more use the presentation method of text combined with technical achievement maps;it occupies a small space,and the selection of materials is concise,coherent and continuous,In accordance with the layout: methods and procedures for studying substances-the use of chemical reactions and technical means to achieve the use and transformation of elements-organic synthesis technology.The technical capability content and technical tools in the Jiangsu Education Edition have more rational content,accounting for a balanced proportion.There are many high-tech fields,but the principles are complex;they occupy a large space and are mostly concentrated in the main text and columns,and use industrial flowcharts and texts.The method focuses on linking industrial production practices;the layout is clear,consistent,and consistent with: the method of studying substances-chemical substances and technology-chemical reactions and technology-organic synthesis technology-chemistry,technology,society,and the environment.
