Analyzing the relationship between public social attention and teaching research on professional academic platforms can provide a reference for identifying and extracting hot topics in academic literature. As a subject with equal emphasis on theory and practice, information technology is critical for students to develop information emotion and morality. Therefore, based on the CNKI database and Baidu Index from 2011 to 2021, this paper analyzes the complex correlation and dynamic characteristics between public attention and teaching research from the perspective of “high school information technology” by using the methods of keyword word frequency analysis、pearson correlation coefficient and LOOCV cross-validation. The results show that: 1) The hot topics in the field of high school information technology mainly focus on seven words in recent ten years; 2) From the perspective of “high school information technology,” there is a strong correlation between public attention and teaching research, and the research points of professional academic literature tend to be more and more hot issues of public concern; 3) The focus of attention on high school information technology is gradually shifting; 4) The volume of teaching research literature with the theme of “high school information technology” will grow slowly in the next 2-3 years. Therefore, it is necessary to fully explore the critical points within the subject of information technology, break the limited diversification of the subject research, expand the research space of the subject field, and improve the quality and quantity of literature research.
