Research on Mathematics Extracurricular Activities in Middle School in China

Mathematics extracurricular activities are not only conducive to students’ all-round development, but also a beneficial supplement to the current classroom teaching. In this study, 30 pieces of literature on mathematics extracurricular activities in middle school from 1993 to 2022 were selected from the database of China Knowledge Network（CNKI) as the data source. This paper qualitatively analyzed the literature to summarize and sort out the previous research and found that: (1) Current domestic studies mainly focus on the following four aspects: classification, forms and content of mathematics extracurricular activities; organizing principles of mathematics extracurricular activities; issues needing attention in mathematics extracurricular activities; evaluation of mathematics extracurricular activities. (2) The forms of mathematics extracurricular activities are various, mainly including extracurricular mathematics groups, mathematics special lectures, etc. The principles of organizing mathematics extracurricular activities have been studied very thoroughly. Previous studies have mainly discussed the issues needing attention from activity implementation, content selection, students and teachers. There are few studies on the evaluation of mathematics extracurricular activities. (3) Researchers mainly collected data based on observation and experience, and some researchers draw conclusions based on theoretical speculation or teaching experience, lacking strict experimental verification. Therefore, future research needs to adopt more scientific research tools, expand the scope of research, increase verification research, and give more scientific and effective suggestions, to make this research more comprehensive, systematic and profound.
