Monitoring and Analysis of English Classroom Teaching Quality Based on Big Data

In order to deal with the problems of low evaluation accuracy and long evaluation time in the traditional English classroom teaching quality monitoring and evaluation methods, this study proposes an English classroom teaching quality monitoring and evaluation method based on big data. According to the selection principle of English classroom teaching quality monitoring factors, this study analyzes the English classroom teaching quality monitoring factors, constructs the English classroom teaching quality monitoring index system, obtains the monitoring index data, filters and compresses the monitoring data, and takes the preprocessed English classroom teaching quality monitoring data as the evaluation index. This study uses the principal component analysis method to calculate the weight of the English classroom teaching quality evaluation index and constructs an English classroom teaching quality evaluation model. The simulation results show that the proposed method has high accuracy and short evaluation time.
