《新课程标准》的基本理念指出，学生是数学学习的主人，教师是数学学习的组织者、引导者与合作者。关注人是新课程的核心理念。数学新课程的重要原则是“以学生为本”，最终目的是促进学生全面发展，而课堂上的“互动”则是达到此目的的重要方法或手段。新的课程理念将师生互动这一环节提升到了重要的地位，同时也提出了更高的要求。本文在了解师生互动方式和原则的基础上，对数学概念互动教学的策略进行研究。

The basic idea of new course standard point out that the student is the master of mathematics study, while the teacher is the organizer、guider and collaborator of the mathematics study. Pay attention to the student is the core mind of the new course. The aim of new maths course is making the students do a complete progress, and the “interaction” in class is a important measure to achieve the purpose. The paper mostly tells about the manner and principle of the interaction, and introduce the design of a part of maths study—the concept of mathematics.
