在本发明的一个实施例中，教师终端100从多个学生终端200中选取一个学生终端进行答题，并向该被选取答题的学生终端发起开始答题指令。
教师终端100将被选取进行答题展示的学生终端的屏幕内容显示在自身终端，再通过投屏的方式或者外接投影的方式将自身屏幕内容显示在大屏显示装置。
在本发明的一个实施例中，教师终端100还用于获取用户使用智能笔或电容笔在上课内容上做的批注信息，将所述批注信息与上课内容合成后保存到云端服务器，所述批注内容包括批改、修改、打分、标注等。其中，教师终端100获取用户使用智能笔在上课内容上做的批注信息具体为：教师终端100与智能笔建立配对连接；获取智能笔在教师终端100屏幕上的笔迹信息，将所述笔迹信息在所述上课内容上进行同步绘制生成批注信息，所述上课内容的背景上设置有采用点阵排列的网格。
在本发明的一个实施例中，课堂教学互动系统还包括同屏设备(未在图6中示出)，教师终端100，还用于获取上课内容进行显示，与同屏设备建立投屏连接，对自身屏幕进行录制，将录制的屏幕内容实时发送至同屏设备；学生终端200，还用于与同屏设备建立分屏连接，接收同屏设备发送的教师终端100的屏幕内容，将教师终端100的屏幕内容显示在同屏窗口；同屏设备，用于与教师终端100建立投屏连接，与各学生终端200建立分屏连接，解析教师终端100发送的屏幕内容进行显示，并对自身屏幕进行录制，将录制的屏幕内容实时发送至各学生终端200。
上述实施例通过教师终端向一个或多个学生终端发起开始答题指令，一个或多个学生终端接收到开始答题指令后，获取智能笔在书写本上的笔记信息同步绘制在学生终端进行答题，其中，被选取进行答题展示的学生终端将自身屏幕内容实时发送至教师终端，教师终端将该被选取进行答题展示的学生终端发送的屏幕内容通过大屏显示装置进行显示。采用本发明的方法，一方面使得用户不需要改变书写习惯即可以快速完成主观题型的答题，提高用户数字化答题的体验及效率，另一方面，可以像传统在黑板上答题那样将答题过程和结果实时展示给整个班级的学生，大大增强了课堂的互动效果。
上述本发明实施例序号仅仅为了描述，不代表实施例的优劣。
本领域普通技术人员可以理解实现上述实施例方法中的全部或部分流程，是可以通过计算机程序来指令相关的硬件来完成，所述的程序可存储于一计算机可读取存储介质中，该程序在执行时，可包括如上述各方法的实施例的流程。其中，所述的存储介质可为磁碟、光盘、只读存储记忆体(Read-Only Memory，ROM)或随机存储记忆体(Random Access Memory，RAM)等。
