摘　　要：目前针对课堂教学效果的研究很多,大多依据源于问卷调查之类的主观数据,但是将主观数据作为依据得到的结果是否准确有待商榷。本文针对学生上课期间的姿态、表情等视频信息进行提取的关键帧进行分析,客观地直接获得学生上课期间的学习状态信息,以该表现为依据,针对教师整个授课期间或者部分授课时间或者某一个知识点的学生表现提醒教师继续沿用或者改进授课方式、方法,从而达到更好的授课效果。Nowadays,there are many methods for teaching effects in class according to question survey,however,the result is not accuracy for this kind of subjective data. In this paper,we analyze the pose,expression of faces and so on abstracted from students in class,then we can objectively obtain the information from the pose of student＇s studying,according to this,we can remind teachers keep or modify the method and means while teachers give the lecture,and then we get the better results of teaching students.
