【摘要】 师生互动作为课堂互动最主要的方式，其水平直接影响着课堂教学的质量。优质课可以在某种程度上反映一个地区的优质教育水平。以“一师一优课”平台中河南省的两节优质课为样本，采用方海光教授设计的改进型弗兰德斯互动分析系统（iFIAS），从课堂互动结构特征、教学风格特征、师生情感氛围、师生问答特征、动态曲线特征等五个方面进行分析。研究发现，合理的师生语言比例结构，更有利于形成课堂的良性互动；正向的师生情感互动，能促进课堂形成良好的互动氛围；充分发挥课堂提问的积极作用，能提升课堂的整体效果。因此，应调整语言比例结构，营造积极课堂氛围，增强信息技术与课堂的融合力。更多还原

【Abstract】 As the most important way of classroom interaction, teacher-student interaction directly affects the quality of classroom teaching. High quality courses can to some extent reflect the high-quality educational resources of a region. Taking two high-quality courses in Henan Province as samples, the improved Flanders Interactive Analysis System(iFIAS) designed by Professor Fang Haiguang is used to analyze the characteristics of classroom interaction structure, teaching style, teacher-student emotional atmosphere, teacher-student question-and-answer characteristics, and dynamic curve characteristics. It is found that reasonable teacher-student language ratio structure is more conducive to the formation of benign classroom interaction; Positive emotional interaction between teachers and students can promote the formation of a good interactive atmosphere in class. Giving full play to the positive role of classroom questioning can improve the overall effect of the classroom. Therefore, should adjust the language proportion structure, create a positive classroom atmosphere, and enhance the integration of information technology and classroom.更多还原
