Problems solved by technology

Although domestic colleges and universities have been able to monitor classroom teaching in real time, most colleges and universities have not yet been able to analyze and obtain effective information from the collected information to improve the evaluation of classroom quality
Although there have been many related researches on the evaluation of classroom learning quality in China, there are still several limitations: (1) There is no clear definition of the dividing line between attention and concentration, and the two are combined; (2) Ignore the influence of seat distribution on classroom attention; (3) Ignore the reason orientation of the front row of students

Embodiment 1

[0068] This embodiment provides a method for comprehensive evaluation of students' listening level based on attention and concentration, such as figure 1 , including the following steps:

[0069] S1: Collect classroom teaching video data during the current class, and obtain student behavior information during the lecture process;

[0070] S2: According to the student behavior information, calculate the student's attention level and concentration level;

[0071] S3: Obtain the student's listening level during the current class based on the student's attention and concentration.

[0072] In step S1, the classroom teaching video data of the current class is collected, and the student behavior information during the lecture is obtained, such as figure 2 , including the following steps:

[0073] S1.1: Collect the classroom teaching video of the current class, extract the image at the set frame interval, store the read frame as a picture and store it as a picture set in the orde...

Embodiment 2

[0117] This embodiment has the same steps as Embodiment 1. In the specific implementation process, the course quality evaluation of the semester is carried out based on the 16 class hours of the student's listening level W of the course:

[0118] TCQ=γ D / 2 ·Z α / 2 ·Σ (α+D+2) / 2 ·exp[-0.5(Tr[Z·Σ -1 ]+γ(μ-V) T Σ -1 (μ-V)γ D / 2 )]+b

[0119] Among them, γ and α are parameters, Z is a C×D-dimensional matrix, D is the number of semester-divided modules, C is the number of class hours divided into different semester sub-modules by the total class hours; V is D×D for different semester sub-modules 1-dimensional weight matrix; Σ is C×D covariance matrix; Tr[Z] is the rank of matrix Z; μ is D×1 weight mean matrix, such as weight matrix V is [a,b,c,d] T , set e=(a+b+c+d) / 4, then the matrix μ is [e,e,e,e] T . b is a constant.

[0120] This course has a total of 16 class hours. If D is set to 4, it is 4 semester sub-modules, which are: the beginning of the semester, before the mid-...

Abstract

The invention discloses a comprehensive assessment method for student lecture attending level based on attention and concentration degree, comprising the following steps: S1, collecting current classhour classroom teaching video data, and obtaining student behavior information in a teaching process; S2, calculating student attention level and concentration degree level according to the student behavior information; and S3, obtaining the lecture attending level of the current class based on the attention and concentration degree of the student. On the basis of attention and concentration indexes, a classroom level assessment method is constructed, the difference of teaching level standards of different schools is overcome, and the classroom teaching quality is assessed in a targeted mode.

Description

technical field [0001] The present invention relates to the field of educational informatization, and more specifically, to a method for comprehensively evaluating students' listening levels based on attention and concentration. Background technique [0002] With the increase of enrollment in colleges and universities and the development of education reform, the quality of higher education has become a hot spot of social and public concern. In our country, colleges and universities still use classroom teaching as their main form of teaching, and the quality of classroom teaching has a direct and important impact on the quality of personnel training. Quality is the core of higher education. In the evaluation of teaching quality in colleges and universities, the evaluation of classroom learning quality is one of the more important links. Traditional classroom monitoring is mostly controlled by the teacher himself. While in class, he still manages the discipline and the attent...
