Classroom teaching effect evaluation method and device

Abstract

The embodiment of the invention provides a classroom teaching effect evaluation method and device. The method includes: collecting electroencephalogram data of all classroom participants in the same time period through the same collection frequency; calculating the correlation between the electroencephalogram data of every two classroom participants, taking the correlation as a consistency index between the electroencephalogram data of every two classroom participants, finally obtaining the consistency index between the electroencephalogram data of all the classroom participants through a method of calculating an average value, and evaluating the classroom teaching effect through the consistency index. According to the method and the device, the classroom teaching effect is evaluated basedon the consistency among the electroencephalogram data of all the classroom participants; the method and device overcome the limitation of classroom teaching effect evaluation based on electroencephalogram data of a single classroom participant in the prior art, can effectively and accurately evaluate the classroom teaching effect so as to ensure the accuracy of the classroom teaching effect evaluation result, and can be widely applied to evaluation of other group activities.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of data processing, and more specifically, to a method and device for evaluating classroom teaching effects. Background technique [0002] Education is of great significance to individuals, families, society and the country. Among them, classroom teaching is the most important form of teaching activities in basic education at present, and the effect of classroom teaching is the basis and key to the quality of education. Therefore, how to objectively and effectively evaluate classroom teaching effects has attracted much attention. [0003] The traditional classroom teaching effect evaluation mainly relies on subjective reports, including teachers, students and experts outside the classroom to score the interaction process, students' academic performance and so on. In recent years, the development of human neurophysiological signal sensing technology has provided new solutions for e...
