中文摘要：

使用Wi-Fi模块进行数据传输，通过ARMCortex-M3内核的微控制器，设计了基于Wi-Fi的互动教学助手的学生端，可以实现上课签到，回答问题（选择题、判断题、问答题），匿名对教师的评价等功能。设备体积小，便于携带，使用方便。系统可以使教师通过统计的真实数据（学生到课率、题目正确率、对教师的评价）实时了解学生对知识点的掌握情况，及时调整课堂进度，实现高效的课堂教学。

英文摘要：

Data transmission is implemented by using wireless fidelity (Wi - F i). By using micro controllerunit (MCU) based on advanced RISC machines (A RM ) Cortex- M3 kernel, the student side of theinteractive teaching assistant based on Wi - Fi isdesigned to achieve classattendance, answering questions(multiple choice, true or false, questions and answers) , anonymous evaluation of teachers and other functions. This system allows teachers to understand the level of students'mastery of knowledge in real timethrough the real data statistics (attendance rate, correct rate, evaluation of teachers), and timely adjustthe teaching schedule, and achieve efticient classroom "teaching.
