Literature Metrology Analysis Of The Evolution Trend Of Chemistry Teaching In Middle Schools Of China Since The New Curriculum Reform

China has been reforming curriculum reform for more than ten years since 2003.With the deepening of the reform of middle school chemistry education,deepening of teaching research topics,the increasing number of teaching research literature year by year,based on this,the econometric analysis of the literature of chemical research is particularly important.This paper uses the method of Bibliometric Analysis to analyze the hotspots of chemistry teaching in middle schools in China,and reveals the research hotspots and evolution of chemistry teaching in middle school in China in 2003-2016,which provides reference for the further development.In specific content analysis,this paper bases on CNKI database,selects three representative journals of middle school chemistry education in China,source of CSSCI journals,Ph D thesis to recognize in the middle school chemistry teaching research in the field of sample data as object of literature analysis,using Excel,Citespace V information visualization software and bibliography Bicomb2.01 co-occurrence analysis system software to analyze the analysis research.Firstly,this paper analyzes the literature of Chinese middle school chemistry teaching,we can understand the growth trend,the dispersion of journals,the author's unit situation.Secondly,through the analysis of the con-occurrence and clustering network of keywords,are understood the main research content and research focus of this field.Finally,through the analysis of the bursts and time zone view of keywords,are understood the evolution trend and future research direction of this field.Based on the analysis of the above data,the author mainly comes to the following conclusions:(1)the total number of literatures in the study of chemistry teaching in middle schools in China in 203-2016 is gradually increasing;(2)The researchers mainly focus on normal universities and their research institutes;(3)Three types of high school chemistry education journals have the largest number of articles;(4)The main research hotspots focus of the research literature are student's cognitive structure,ability training,the course concept and the material content analysis,teacher's teaching means,student's learning methods,auxiliary teaching and other fields.The research trends mainly present the wave development.The type of increasing is teaching strategies,effective teaching,situational teaching,mind mapping,autonomic teaching,etc.The type of weakening is inquiry-based teaching and inquiry-based learning,teaching media,etc.The gurgitation type is cooperative learning,cooperative inquiry,scientific inquiry capacity,thinking ability,emotional attitude,new curriculum principle and reform.
