基于手机APP的无线教学反馈系统研究

摘要

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 effec-tively,Mobile phone terminals connect themselves with the host computer via Wi-Fi and provide an effective platform for infor-mation 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WCRS是通过无线手持终端，实现课堂中学生与教师的互动交流，以图表形式实时显示学生反馈信息的教学应用系统。基于手机APP的WCRS摆脱了手持终端硬件的约束，有效降低了系统部署成本，具有更大的灵活性、方便性和经济性。手机终端通过Wi-Fi与上位机相联，为教学互动信息采集、交流、实时展示提供了有效的平台。论述了国内外WCRS产品的发展现状及发展趋势。对基于手机APP的WCRS软硬件系统架构设计及其实现方法进行了较为全面的介绍与评价。
