The development of CRS (classroom response system) , its application environments and the impact on the teaching are presented. A CRS is an electronic response system that bridges the interaction between students and instructors, and supplies technical support for multimedia learning modules and the teaching reforms. In order to investigate the effect of CRS, a controlled study based on the Introductory Physics course for the non-physics majors was carried out. A total of 383 students were randomly assigned to two groups. One group is the experimental one using CRS, and the other is the controlled group. The results show that the experimental group outperforms the other.%介绍了课堂交互反馈系统CRS的发展、应用环境、对于教学的意义以及在我国的初步应用.CRS是最近进入我国高校的多功能新教育技术,它利用无线通信实现师生间的课堂互动,为教学模式的更新和教学方法的多样化提供了技术支持.基于大学物理课程对383名本科生进行的对比教学实验,结果表明,CRS通过实现课堂上大量学生与教师的集体实时反馈,有效地增强了学生的学习效果.
