在课堂教学中,师生双方的交往互动是决定数学课堂教学效益的重要基础,教师应该摒弃传统教学中教师“一言堂”的教学弊端,扎实推进学生的交往互动效益。提出在资源运用中创设互动情境、在自主探究中建构知识模型、在结构优化中加速心理驱动、在策略遴选中实现高效互动,促进学生数学学习效益的有效提升。 In classroom teaching, interaction between teachers and students is an important basis for determining the effectiveness of mathematics classroom teaching. Teachers should abandon the teaching shortcomings of teachers in traditional teaching and promote the interactive benefits of students. This paper proposes to create interactive situations in the use of resources, construct knowledge models in self-exploration, speed up psychological drive in structural optimization, and achieve efficient interaction in strategy selection so as to promote the effective promotion of students’ mathematics learning benefits.
