Embodiment 1

[0023] An Internet teaching assistant teaching system based on the evaluation of key teaching points, including:

[0024] The student terminal image acquisition device collects the facial images of the students being evaluated;

[0025] The information transmission device is used to transmit the facial image collected by the student terminal image collection device to the classroom behavior analysis processor;

[0026] The classroom behavior analysis processor judges the students' emotions and concentration through the processing of facial images, and classifies the students' emotions when learning multiple knowledge points involved in key teaching points, and assigns mastery probability values ​​respectively, which are respectively joy : 100% mastery rate, calm: 95% mastery rate, negative: 90% mastery rate; classify the degree of concentration in the lectures and give mastery probability values ​​respectively, which are concentration: 100% mastery rate, neutral: 95% mastery r...

Embodiment 2

[0073] The difference from the embodiment is that the key teaching point automatic classification and storage module divides the teaching video according to the association with the key teaching point, and then marks the sections. When the user watches the teaching video, the progress bar is provided with a segmentation point, and When the mouse moves to the position of the split point, key teaching point keywords will be displayed, so that users can quickly locate the video position of relevant key teaching points.

Abstract

The invention discloses an internet teaching auxiliary teaching system based on the key teaching point evaluation. The system comprises a student terminal image collection device which collects a face image of an evaluated student; an information transmission device used for transmitting the face image acquired by the student terminal image acquisition device to the classroom behavior analysis processor; a class behavior analysis processor used for classifying emotions of the students when learning a plurality of knowledge points related to the key teaching points and respectively endowing the emotions with mastering probability values; an intelligent classroom device used for realizing teaching interaction with the student terminal, and automatically judging whether the corresponding knowledge points are mastered or not according to the correct and wrong conditions of all questions in the teaching interaction; and a key teaching point evaluation device which calculates the total mastery rate of the key teaching points according to the analysis and judgment results of the classroom behavior analysis processor and the intelligent classroom device. According to the system, related videos of the key teaching points can be conveniently and quickly found according to the mastery condition of the key teaching points. The course look-back is effectively carried out based on recording and playing courses.

Description

technical field [0001] The invention relates to the technical field of information-based teaching, in particular to an auxiliary teaching system. Background technique [0002] Although the current Internet teaching system also records courseware into videos for users to review, the recorded video is only a complete video file, and no further processing is performed on the video file. When users look for key teaching points related For videos, you can only find them manually. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an Internet teaching assistant teaching system based on the evaluation of key teaching points, so as to facilitate the positioning and review of videos related to key teaching points. [0004] In order to solve the above-mentioned technical problems, the present invention adopts the following technical scheme: the Internet teaching auxiliary teaching system based on the evaluation of key teachi...
