【摘要】：追求教学效率是教学的本质特性,也是当前课程改革的重要目标;而课堂是教师提高教学质量,实现有效教学的主战场。当前教师主要采用课堂观察和提问的方式与学生交互,无疑会因个人精力不足等原因,造成信息传递与反馈的片面性与滞后性。信息技术的高速发展,特别是视频监控系统的智能化发展,为弥补上述问题提供了可能。结合现有智能监控设备设计的课堂教学评价系统,利用多姿态人脸检测和面部表情识别技术,及时获取学生在学习过程中的情绪变化,反馈给教师,帮助教师准确全面地掌握所有学生在课堂教学中的参与情况。该系统不仅能够自动跟踪及分析教学过程中学生的整体状态,有效掌控课堂教学过程;还可指定跟踪对象,对指定对象在课堂中的状态进行统计分析,以便进行个体的针对性指导以及学习问题的及时矫正。
[Abstract]:The pursuit of teaching efficiency is not only the essential characteristic of teaching, but also the important goal of the current curriculum reform. Classroom is the main battlefield for teachers to improve teaching quality and realize effective teaching. At present, teachers mainly use classroom observation and questioning to interact with students, which is undoubtedly due to lack of personal energy and so on. The one-sidedness and lag of information transmission and feedback, the rapid development of information technology, especially the intelligent development of video surveillance system. Combined with the classroom teaching evaluation system designed by the existing intelligent monitoring equipment, multi-pose face detection and facial expression recognition technology are used. Timely acquisition of students in the process of learning emotional changes, feedback to the teacher. The system can not only automatically track and analyze the whole state of the middle school students in the teaching process, but also effectively control the classroom teaching process. The tracking object can also be assigned and the state of the specified object in the classroom can be statistically analyzed in order to guide the individual and correct the learning problem in time.
