Research And Analysis On The Thesis Of Master And Doctoral Degree In Educational Technology In China

In recent years,with the rapid development of information technology,the subject of educational technology has been paid attention to in various fields of society.According to the needs of discipline development and the requirements of national education informatization reform,colleges and universities also vigorously develop the discipline of educational technology.As an emerging interdisciplinary and interdisciplinary applied discipline,the development of educational technology in China is relatively late compared with that in western countries,but it has also developed rapidly in recent years.In the process of development,educational technology discipline system and college characteristics with Chinese characteristics have been formed.In order to explore the research hotspots,research contents,and demonstrate whether there are clear differences in the research hotspots and contents of theses from different colleges and universities in the past five years,this study mainly adopts the methods of literature analysis,content analysis,word frequency analysis and cluster analysis Space visualization analysis software is used to analyze the master’s and doctoral dissertations from 2016 to 2020 that can be found in NIKI.First of all,the NIKI database is used to retrieve the preliminary research data,and then the data is filtered,and the data needed for the research is converted according to the format requirements of cite space software analysis,so as to obtain comprehensive and correct data analysis resources.Secondly,classify the research fields and contents of educational technology,as well as the institutions from which the thesis comes.The classification of research fields and content is mainly based on Professor Li Long’s research framework of educational technology,while the classification of the source colleges of the thesis is based on the actual situation of Chinese university construction,in terms of level,type,and location.For classification,because educational technology has two different admission codes,040110 and 078401,and the particularity of granting education,science and engineering degrees at the same time,the source institutions of the thesis are also classified from the perspective of admission codes.The third step is to perform information processing and statistical analysis on the data samples according to the above classification criteria.First,conduct a statistical analysis of the publication time of the data sample and the status quo of the source institution.Then,according to Professor Li Long’s classification of the research field and content of educational technology,the research field and content of the paper are classified and statistics,and then all the data samples Analyze research hotspots,form a keyword knowledge map,keyword timeline diagram,and time zone diagram,and sort out the high-frequency keywords and keywords with centrality greater than 0.2,and then based on the classification results of the source institution of the thesis,Analyze the research hotspots of different colleges and universities,and form a statistical table of the frequency and proportion of high-frequency keywords.In order to further explore the research topics of various research hotspots,a statistical analysis of the number of research papers,source institutions and main themes of each research hotspot is carried out.Finally,conduct comprehensive research,draw conclusions and think.Conduct comprehensive discussion and analysis based on the chart obtained,analyze the current status,research content,and hotspots of master and doctoral papers,explore whether there are major differences in research hotspots from various colleges and universities in the past five years,draw conclusions and do some Thinking.Hope to promote the next research and development of educational technology.
