摘　　要：无线网技术及其应用已遍及生活的各个角落,对人们的工作乃至生活方式带来巨大变革。利用无线网络技术能够有效结合手机设备构建出一个轻松高效的教学互动环境,在传统教学基础上增加终端设备(计算机、移动手机、平板等),教学投影仪图像投放到幕墙的同时,可以同步投影到各个移动终端,大大方便教学过程;学生有疑问可以在线提问,教师也可以远程操作终端演示,对学生学习过程进行监督有效促进教学互动;主要功能包括:考勤签到、屏幕共享、声音共享、文件共享、板书共享、无线麦克风、远程控制、问题讨论、投票统计、随机抽取等。该系统结合无线网络和电脑手机的线上互动,降低教育成本,优化教学环境,提高办学效益,促进教学质量的提高。The wireless network technology and its application have brought great changes to our social life. After joining terminal equipment, projector image can into each terminal, and teaching courseware can share to each terminal and greatly facilitate the teaching and reduce the distance of the projected image. Students have questions can ask questions, and teachers can make remote terminal operation demonstration. The main functions of Inter-Teaching System include attendance sign-in, screen sharing, file sharing, shared blackboard writing, wireless microphone, remote control, problem discussion, voting statistics and random selection. In combination with the wireless network and mobile computer interactive, reduces the cost of education, optimizes the environment of teaching, improves the teaching efficiency and promotes the improvement of teaching quality.
