A Method of Monitoring and Evaluating the Quality of English Classroom Teaching Based on Big Data

Abstract

To improve the reliability and accuracy of quality of English instruction in the classroom monitoring and assessment, as well as to reduce the time spent monitoring and evaluating the quality of English instruction in the classroom, a big data-based approach to monitor and evaluate the quality of English instruction in the classroom is proposed. A frequent itemset mining technique for quality of English instruction in the classroom monitoring data is built based on a study of the theoretical basis of big data and the features of quality of English instruction in the classroom monitoring data. To complete the data transformation of quality of English instruction in the classroom monitoring, the multivalued continuous attribute is quantified and turned into a two-dimensional Boolean data matrix. To mine the frequent itemsets of quality of English instruction in the classroom monitoring data, a frequent itemset mining algorithm based on the compressed matrix is applied. This work creates a quality of English instruction in the classroom evaluation model using the gray correlation method of multiobjective decision-making and weighted gray correlation analysis to realize the monitoring and evaluation of quality of English instruction in the classroom. The experimental results suggest that the proposed method is highly reliable and accurate and that it can significantly reduce the time spent monitoring and evaluating the quality of English classroom instruction.

“…Using the rain classroom, Tsinghua University's teachers can send videos, exercises, audio explanations, and other materials to students and show slides in classes. Meanwhile, students can use Danmu (a form of video commentary used on online videos comprising scrolling through viewer messages posted on top of the video in real time) to give feedback to teachers, answer questions, and express any difficulties they are having understanding the topic; teachers can see students' answers and learning records and use these data for real-time interactions (Wang, 2017).…”
