Illustrate the application of statistical processing software in content analysis with examples (Zhou, Song Jihua. Meta-analysis of graduate dissertations of educational technology, Modern Educational Technology, 2005 (6): 67-70). [Keywords:] content analysis SPSS Chi-square analysis With the development of educational technology, the research method as a symbol of discipline division is naturally deeply rooted in people's hearts. More and more papers in the field begin to use content analysis, but the terms appearing in the papers, such as chi-square test and two-tailed significant probability, are unknown to undergraduates and even graduate students. Based on this situation, the author hopes that students can better understand the application of SPSS in content analysis through this article. In Zhou Wenzhong, the author used the content analysis method to make a meta-analysis of 199 1-2004 domestic postgraduate dissertations on educational technology, and investigated the development, change and development trend of educational technology since 14. Finally, there are some problems in graduate dissertations [1]. Below, the author will briefly introduce the content analysis method, and elaborate on the part applied to SPSS. First, the content analysis method is a special method of educational technology research [2]. Content analysis method was originally developed for social science, which uses the quantitative analysis method of natural science to analyze the content of historical documents. Later, some communication researchers in the United States used this method to analyze the contents of newspapers and understand the trend of information development, and then this method gradually became an important research means of communication. The research object of educational technology is learning process and learning resources. We can use content analysis method to analyze the learning process and resources, and feedback information from learners' learning responses, which is one of the effective ways to master educational technology books and laws. The characteristics of content analysis method are obvious, objective, systematic and quantitative. Quantization means that the results of content analysis can be expressed by numbers and some mathematical relationship, such as frequency distribution, various percentages or proportions, correlation coefficient and so on.
