A classroom teaching effect evaluation system based on facial expression recognition

Abstract

The invention discloses a classroom teaching effect evaluation system based on facial expression recognition. According to the invention, videos in a classroom are analyzed in real time; the facial expressions of students in class are extracted, and the understanding degree, the activity degree, the doubtful degree and the activity time index information of the students in class are counted and analyzed, so that teachers can know the psychological states of the students and the mastery degree of the students on the knowledge points, the teachers can adopt corresponding teaching regulation andcontrol means, and the teaching quality of the class is improved; The classroom expression state of the teacher is automatically analyzed, the classroom expression index of the teacher is counted, andthe classroom emotion basis is provided for teaching management personnel to examine the teacher.

Problems solved by technology

At present, classroom teaching has the following shortcomings in teaching, learning, classroom teaching evaluation, curriculum reform research, etc.: (1) In terms of teaching, teaching management personnel only assess teachers' classroom performance at a certain time period, which cannot fully and truly reflect Teacher's usual classroom expressions

However, the system for students to participate in teacher evaluation has a lot of subjectivity. Some teachers have the phenomenon of pleasing students without principle. At the same time, it is difficult to understand the teacher's usual teaching expressions in class.

These are not conducive to teachers' scientific improvement of classroom teaching

(2) In terms of learning, since teachers mainly use the method of observing students and asking students to interact with students in classroom teaching, the main energy of teachers is on teaching, and teachers' personal energy is limited, so they cannot take care of each student in the whole class. The classroom performance of the whole class will cause one-sidedness and lag in information transmission and feedback, lack of comprehensive attention to students' emotions, and teachers cannot understand all students' listening situations and carry out effective supervision

(3) In terms of classroom teaching evaluation, the general teaching management personnel obtain conclusions about the facial expressions and attitudes of teachers and students in classroom teaching through investigation, which is time-consuming and labor-intensive, and the evaluation conclusions are also one-sided and subjective

(4) In terms of curriculum reform research, it is difficult to count the teaching effects of the target courses in all schools across the country, and there is a lack of overall data on the teaching effects of the target courses, which cannot effectively promote the curriculum reform

However, in the field of education, facial expression recognition technology has not been well applied
