Problems solved by technology

However, at present, teachers' evaluation of classroom teaching interaction activity is completely subjective, and there is a lack of relevant quantitative evaluation methods
Even some teachers with insufficient teaching experience did not pay attention to teaching interaction, resulting in a depressing teaching atmosphere and a decline in teaching efficiency

Embodiment 1

[0025] Embodiment 1: The image acquisition device is used to collect the image information of the classroom teacher's lecture status at a frequency of 1 frame. The image recognition module recognizes, judges and counts the upper limb movements of the teacher indicating that the students raise their hands according to the information of the teacher's upper limb movement status. The teacher indicates that the students raise their hands A total of 3 times, the first time the maximum number of students raising their hands within 10 seconds is 10 people, the second time is 15 people, and the third time is 20 people. Then in this teaching process, the average number of students raising their hands to answer questions is 15 times.

[0026] During the teaching process, the greater the average number of students raising their hands to answer questions, the greater the activity of classroom teaching interaction, and the evaluation results will be displayed on the computer screen.

Abstract

The invention relates to a classroom teaching interactive activity evaluation system based on machine vision, which comprises the following steps: 1. Collecting teacher lecture state image information; 2. Judge and count the upper limb movement of the teacher's gesture to the students to raise their hands; 3. Collect the image information of students' listening state; 4. Judge and count the students' hand-raising movements; 5. Establish the evaluation model of interactive activity of classroom teaching, and get the average number of students who raise their hands to answer the questions through analysis and calculation, and evaluate the interactive activity of classroom teaching.

Description

technical field [0001] The invention relates to a system for evaluating the activity degree of classroom teaching interaction based on machine vision, in particular to a method for evaluating the activity degree of classroom teaching interaction based on machine vision. Background technique [0002] Teaching interaction is an important part of classroom teaching process. In the process of classroom teaching, the activeness of teaching interaction is closely related to the attention of students in class, the teaching level of teachers, and the charm of personality. The high degree of active teaching interaction indicates that teachers and students have a harmonious teaching relationship, which can significantly improve teaching efficiency. However, at present, teachers' evaluation of classroom teaching interaction activity is completely subjective, and there is a lack of relevant quantitative evaluation methods. Even some teachers with insufficient teaching experience did n...
