The objectives are to solve the problems existing in the current ideological and political theory courses, such as the difficulty of classroom teaching quality assessment, the confusion of teachers' classroom process management, and the lack of objective assessment basis in teaching quality monitoring. Based on Artificial Intelligence (AI) technology, a designed evaluation method is proposed for teachers' classroom teaching and solves some problems such as high system cost, low evaluation accuracy, and imperfect evaluation methods. Firstly, the boundary algorithm system is introduced in the research, and the Field Programmable Gate Array (FPGA) by deep learning (DL) is used to accelerate the server hardware network platform and equipped with pan tilt zoom (PTZ) and manage multiple AI + embedded visual boundary algorithm devices. Secondly, the network platform can manage the PTZ and focal length of Internet protocol (IP) cameras, measure, and capture face images, transmit data, and recognize students' face, head, and body postures. Finally, classroom teaching is evaluated, and students' behavioral data and functions are designed, debugged, and tested. The research results demonstrate that the method overcomes the problem of high system cost through edge computing and hardware structure, and DL technology is used to overcome the problem of low accuracy of classroom teaching evaluation. Various indicators such as attendance rate, concentration, activity, and richness of teaching links in classroom teaching are obtained. The method involved can make an objective evaluation of classroom teaching and overcome the problem of incomplete classroom teaching evaluation.
目的是解决当前思想政治理论课存在的问题,如课堂教学质量评估困难、教师课堂过程管理混乱、教学质量监控缺乏客观评估依据等。本研究引入边界算法系统,利用深度学习(DL)的现场可编程门阵列(FPGA)加速服务器硬件网络平台,并配备云台变焦(PTZ)和管理多个 AI + 嵌入式视觉边界算法设备。其次,网络平台可以管理 PTZ 和 IP 摄像机的焦距,测量和捕捉人脸图像、传输数据以及识别学生的面部、头部和身体姿势。最后,对课堂教学进行评估,并设计、调试和测试学生的行为数据和功能。研究结果表明,该方法通过边缘计算和硬件结构克服了系统成本高的问题,并且使用 DL 技术克服了课堂教学评估精度低的问题。获得课堂教学中出勤率、注意力集中程度、活动度和教学环节丰富度等各种指标。所涉及的方法可以对课堂教学进行客观评价,并克服课堂教学评价不完整的问题。
