[0031] The first embodiment provided by the present disclosure is an embodiment of a method for monitoring teaching effect.

[0032] Combine below figure 1 Embodiments of the present disclosure will be described in detail.

[0033] Step S101, acquiring live video streams of students attending lectures sent by multiple acquisition sources.

[0034] The collection source refers to the camera installed on the student end in the live teaching.

[0035] The purpose of obtaining live video streams of students listening to lectures sent by multiple acquisition sources is to improve the reliability of evaluating teaching effects.

[0036] In step S102, the video time stamp of each live video stream is obtained based on preset extraction rules, and images of students attending lectures are extracted from the live video stream based on the video time stamp.

[0037] The preset extraction rules are used to define the rules on how to obtain video timestamps.

[0038] Timestamp refers ...

Abstract

The invention provides a teaching effect monitoring method and device, a medium and electronic equipment. The method comprises the following steps: acquiring live video streams sent by a plurality ofacquisition sources and used for students to listen to lessons; acquiring a video timestamp of each live video stream based on a preset extraction rule, and extracting student listening images from the live video streams based on the video timestamps; performing face recognition on the student listening image to obtain a student face image; and inputting the student face image into the teaching effect analysis model to obtain a corresponding teaching effect type. According to the invention, the teaching effect type of each student is obtained by analyzing the student face images within the same time threshold, and then the teaching effect evaluation is obtained by counting the teaching effect types. Therefore, the problem of evaluating the teaching effect of teachers in remote live streaming teaching is solved, the live streaming teachers can be assisted in improving the teaching process, and meanwhile live streaming schools can be assisted in selecting excellent teachers more objectively.

Description

technical field [0001] The present disclosure relates to the field of computer technology, in particular, to a method, device, medium and electronic equipment for monitoring teaching effects. Background technique [0002] Distance education is a form of education that adopts multiple media methods for systematic teaching and communication, and is an education that transmits courses to one or more student terminals outside the campus. Modern distance education refers to the education in which courses are delivered to distance students through audio, video and computer technology including real-time and non-real-time. [0003] Live teaching is a form of distance education, which is to carry out distance teaching in the form of real-time video. Its advantages are: a wide range of teaching, not limited by the number of venues and personnel, and direct teaching interaction and on-site Q&A. Live teaching is a distance education method that is closest to on-site teaching. Since ...
