Evaluation System of College English Teaching Based on Big Data

Abstract

Teaching quality is the fundamental guarantee for colleges and universities(CAU) to achieve their educational goals, and is the basis for training talents. In recent years, an important research field of big data is the research of Data mining(DM). The use of DM algorithms can find out the key factors affecting teaching quality, provide a strong basis for teaching arrangements and teaching management in universities, and then improve the teaching level of universities. The purpose of this article is to study the evaluation system of college English teaching(ET) based on big data. Based on the idea of DM, this paper designs and implements a college ET quality evaluation system(ETQES), and applies the system to the college ET quality monitoring system, and obtains a large amount of evaluation data. This paper extracts relevant data from the school’s ETQES, teacher management system, comprehensive educational administration and other system databases, and builds a data warehouse through data preprocessing. This paper implements the DM module of the ETQES to mine the data in the data warehouse. Through the analysis of these rules, the factors affecting the evaluation results of ET quality are obtained. This paper establishes a database suitable for mining association rules. Through the analysis of association rules, find out which key factors can affect the quality of ET, so as to provide a strong basis for ET decision-making and management. According to the experimental results, it can be concluded that the 4555-year-old teacher gets a higher student evaluation score, indicating that teachers of this age group are more popular with students.

[Retracted] Design of Regression Model for MultiParameter Evaluation of English Pronunciation Quality

“…In terms of regression, this form is just a version of horizontal regression. Te empirical formula is defned by the smallest square [14]. In the univariate linear regression analysis, we study the relationship between two variables, one is the common variable x, and the other is the random variable y.…”

Evaluation and Application of College English Mixed Flipping Classroom Teaching Quality Based on the Fuzzy Judgment Model

“…However, at present, there are the following problems in college English teaching [8,9]: (1) the credit hours are significantly reduced, and the scale of teaching classes is huge. As colleges and universities constantly update their talent training programs, college English is also facing subversive teaching reforms.…”

English Network Teaching Model and Design of Evaluation System Based on Association Rule Algorithm

“…Genetic algorithm is used in the data organization model. The data input model is the basic information for the system to set the user data, containing the learner's English level, the user's learning purpose, and the total amount of learned content (Tan, 2021). The English level of the user can be selected from the cluster analysis data, and a level can be selected in the operating system.…”
