Research on the Hierarchical Teaching Method of University English Based on Artificial Intelligence Wireless Network

Abstract

University English is one of the basic core courses for all university students. The course involves many difficult concepts and grammatical structures, so it is difficult to most students. The starting point in any teaching program is to determine whether teaching is needed to specify what that teaching should accomplish. So the students’ need is of vital importance to the success of university English teaching. Traditional university English teaching does not take into account students’ individual learning abilities and feedback, which would cause students to not grasp enough the key knowledge, and then make students lose their interest in English. The development of artificial intelligence technology is becoming more and more mature, especially in the application of English teaching, which promotes the reform, development, and modernization of English teaching. Hence, in this paper, we propose a hierarchical teaching method for the university English teaching platform and employ artificial intelligence to find the needs of university students and know about the mastering knowledge of students. Initially, the dataset is preprocessed using normalization, and then, the feature extraction is performed using principal component analysis (PCA). For classification of the data, we employ the K -means clustering algorithm. To enhance the evaluation system, the whale optimization algorithm (WOA) is used. The performance of the proposed system is analyzed, and it is shown that the average score of students who used the proposed platform to learn university English is far higher than those students who did not use the platform. Hence, the platform can improve students’ autonomous learning and English abilities.

An Optimization-Based Artificial Intelligence Framework for Teaching English at College Level Under Tribhuvan University

“…Utilizing the whale optimization algorithm (WOA), the evaluation system is improved. Traditional university English instruction fails to take into consideration individuals' unique learning styles and evaluations, which results in students not understanding the language well enough and losing interest in it (Zhang and Ji (2022)). Zhai et al, (2021) analyzed the content of works that attempted to highlight AI's applications in education and investigate the field's possible future research trends and problems.…”

Minimizing Emotional Labor through Artificial Intelligence for Effective Labor Management of English Teachers

“…General overview of teachers' emotional labor Figure 2 shows that teachers' total emotional labor scores are approximately normally distributed, with a skewness of 0.229, indicating that the long tail of the distribution curve is to the right, slightly skewed to the right. Among the scores of each dimension, emotional labor perception topped the list, followed by deep behavior, then natural behavior, while superficial behavior had the lowest score [26][27][28].…”
