Study on Secondary School Mathematics Teaching Based on Blended Teaching Model in China

Blended teaching is of great significance for improving the quality of secondary school mathematics teaching and students' interest in learning mathematics. In recent years, some scholars have done research on the blended teaching model of secondary school mathematics, but there has not been any literature to sort out and summarize them. In order to determine the aspects included in the current research on secondary school mathematics teaching based on blended teaching, and to identify the deficiencies in the current research. This paper adopts the method of literature analysis to analyze the previous studies. That's 14 articles in all and draws the following conclusions: (1) Previous research mainly focuses on five aspects, the analysis of the current situation, the connotation of blended teaching, the advantages and significance of blended teaching, the implementation strategy of blended teaching in secondary school mathematics, and specific cases. (2) The research methods are relatively single, mainly qualitative research and less quantitative research. (3) The researchers are mostly teachers in secondary schools, and there are fewer studies by university professors and educational experts. (4) The research content are similar, most scholars have divided the blended teaching into three phases: before, during and after class, respectively, starting from how to do it online and offline, and the combination of online resources and offline teaching is shallow. (5) There are still some blank spots to be researched. For example, the challenges and deficiencies of blended teaching in secondary schools in China and how to deal with them; how blended teaching should be carried out in rural and remote areas; how to evaluate under blended teaching of mathematics in secondary schools. Therefore, it is necessary for future research to conduct deeper research on secondary school mathematics teaching under blended teaching with diversified research methods.
