在安卓开发平台上研究和设计了互动教学应答系统，实现了在课堂教学中教师、学生间新的教学模式。系统包含教师端计算机和学生端手机两大部分，教师利用计算机多媒体提出问题，学生使用手机应答软件提交答案。教学计算机与学生端手机通过无线通信传输信息，并实时统计显示答题情况，教师据此调整教学进度，实现教学互动。通过分析Android应用程序的特点，基于Android SDK和Windows应用程序接口，结合无线通信技术与TCP的Socket通信原理，实现了整个系统的设计。%An interactive instructional response system is studied and designed on the Android platform. This system can realize new teaching model in classroom. The system contains two parts:teacher’s computer and students’ mobile phones. Students submit answers with their mobile phones’ answering software when teacher asks questions by computer multime-dia. Teaching computer communicates with students’ mobile phones through a wireless router and shows the result after real-time statistics. Accordingly the teacher can adjust the teaching schedule to achieve interaction between the teacher and students. Finally,the whole system is realized based on Android SDK and Windows application program interface, through the analysis of the characteristics of Android application and combination with the wireless communication tech-nology and TCP Socket communication theory.
