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.
