及时获得学生的课堂反馈对优化课堂教学过程、改善教学质量有着特别重要的意义，和之前使用短距离无线通信设备的系统不同，本文考虑到了近几年来智能手机的飞速发展，使用智能终端实现了该系统，改善了之前的设备局限性。本文基于提高学生的学习质量，丰富教学场景，形成多元化的评价考察模式，减轻教师的工作量，强化学习和教学成果的角度出发，研究并设计了在课堂环境下采用移动智能手机终端增进师生实时交流的课堂实时反馈系统。本文分析了师生对课堂实时反馈的需求，从课堂教学这一具体应用场景出发，提出了通过移动网络实现学生智能手机与教师电脑终端互联的课堂实时反馈系统的设计方案，并基于 Mac 系统服务器端及 iPhone 移动终端进行了开发实现。经测试，本文设计实现的课堂实时反馈系统可以达到课堂交互的目的，为教师提供真实可靠的教学反馈信息。%Getting timely feedback of students in the classes plays an important part in optimizing teaching procedure and improving teaching quality. Different from previous works using short range devices, we take the rapid develop-ment of smartphones into account, and implement the system using smartphones. In this paper, we design and imple-ment a classroom real-time feedback system based on smartphones. The system helps to improve the students’ learning quality, enrich the teaching scenario, and form the diversification of evaluation model. It is not only useful to reduce work load of teachers, but also enhance the study effect. In our paper, we analysis the needs of students and teachers in classroom, and further propose the designing scheme. Then we implement this system (both server side and client side). We evaluate our system in the evaluation platform, and the results show that our system could achieve the goal of stu-dent-teacher interaction during class, and teachers couls get the real-time feedback.
