在新课改背景下,小数数学教师要尊重学生的主体地位,提高学生在课堂中的参与感,激发小学生的数学学习兴趣。师生互动是有效组织和引导小学生集中精力进行数学学习的重要手段。本文首先分析了师生互动在小学数学教学应用中存在的问题,然后提出了加强小学数学课堂师生有效性互动的措施,仅供参考。 In the context of the new curriculum reform, fractional math teachers should respect the students ’dominant position, enhance the students’ sense of participation in the classroom and arouse their interest in maths learning. Interaction between teachers and students is an important means to effectively organize and guide pupils to concentrate on mathematics learning. This paper first analyzes the existing problems in the application of teacher-student interaction in primary school mathematics teaching, and then puts forward measures to strengthen the effectiveness interaction between teachers and students in primary school mathematics classrooms for reference purposes only.
