Abstract: Wireless classroom teaching response system (WCRS) is a teaching application system, which is realized by wireless handheld terminals to make the interaction between middle?school students and their teachers in classrooms, and display the feedback information of students in diagrammatic form in real time. Based on mobile phone APP, the WCRS, with greater flexibility, convenience and economy can get rid of the constraint of handheld terminal hardware, reduce deployment cost effectively, Mobile phone terminals connect themselves with the host computer via Wi?Fi and provide an effective platform for information gathering and communicationin teaching interaction. The development status and trends of WCRS products at home and abroad are discussed in this paper. The design and implementation of hardware and software system architecture in WCRS based on mobile phone APP are introduced and assessed.

无线教学反馈系统(Wireless Classroom Teaching Response System,WCRS)是透过电子载具(遥控终端),实现课堂中学生与教师的互动交流,以图表方式实时显示反馈信息的教学应用系统[1]。WCRS通过学生手持终端采集学生课堂反馈信息,通过PPT实时反馈汇总信息,以图表形式向学生展示。WCRS能够有效提高师生课堂互动效果,激发学生课堂参与欲望,为教师教学活动调整和教学方案设计提供依据, 从而提高课堂教学效率和教学质量。国外教育机构从20世纪90年代就开始了WCRS的研究和应用,有20多年的应用历史。文献显示,在美国此种系统的普及率达到30%以上,在英国达到35%以上,在加拿大达到50%以上,其中包括高等院校和中小学校,WCRS的教学效果已经得到教育界的普遍认同。WCRS近年来开始在我国高校及中小学中应用,国内已有相应的产品上市。……
