Embodiment 1

[0016] A teaching quantification evaluation method of the present invention is characterized in that:

[0017] (1) Initialize the device hardware; the device is a computer, mobile phone or tablet;

[0018] (2) Set the sampling time interval to 2 minutes, and collect the video and audio signals of the students' faces;

[0019] (3) Determine the student's face position in the video, extract the face key point position of the human face position; extract 6 face key point positions;

[0020] (4) the audio decibel number after filtering out the teacher's audio to the audio signal collected;

[0021] (5) Judge whether the student closes eyes, yawns and nods according to the changing state of the key point position of the human face, and calculates the number of times the user closes eyes, yawns and nods respectively;

[0022] (6) According to the number of times users close their eyes, yawn and nod their heads and evaluate the overall teaching quality of the course: teaching quali...

Embodiment 2

[0026] A teaching quantification evaluation method of the present invention is characterized in that:

[0027] (1) Initialize the device hardware; the device is a computer, mobile phone or tablet;

Abstract

The invention discloses a teaching quantification assessment method. The method is characterized by initializing equipment hardware; setting a sampling time interval to be 2 to 4 minutes and collecting video and audio signals of student faces; determining student face positions in a video and extracting a face key point position of the face positions; filtering audio decibels after a teacher audio for the collected audio signals; according to a change state of the face key point position, determining whether a student closes eyes, yawns and nods; according to frequencies of the student to close eyes, yawn and nod and a noise evaluation, assessing teaching quality of a course in an overall mode. The invention provides an assessment method capable of objectively and quantitatively assessing a teaching level, and the method is easy to operate and is convenient to use.

Description

technical field [0001] The invention relates to the field of teaching evaluation, in particular to a teaching quantitative evaluation method. Background technique [0002] Classroom teaching evaluation refers specifically to the evaluation activities of objects that appear in the course of classroom teaching implementation. Its evaluation scope includes two aspects of teaching and learning, and its value lies in classroom teaching. Classroom teaching evaluation is an important means to promote students' growth, teachers' professional development and improve the quality of classroom teaching. Therefore, how to evaluate classroom teaching scientifically and effectively has become a basic part of modern teaching. It is not only the basis of successful teaching, but also the basis of various educational decisions. The current evaluation methods generally use on-site observation or video recording, and the participants score according to the on-site conditions. However, the exi...
