In recent years, China has accelerated the process of internationalization and made more and more achievements in transnational communication and cooperation. English learning is very important for contemporary college students. And English reading is an important means to acquire English language knowledge, understand external information and improve English language practice ability. Therefore, cultivating college students' English reading ability is a pivotal element in college English teaching. This study will focus on the application of clustering algorithm based on big data framework in the evaluation of college students' English reading ability, aiming at exploring and establishing an effective evaluation model to promote the improvement of college students' English reading ability and academic achievement.

This study explores online self-regulated learning skills among high school students in three schools in China's EAST City Y using questionnaires. Results reveal the online self-regulated learning skills of high school students are positioned at an intermediate level, showcasing noteworthy disparities across distinct cohorts of high school students. Specifically, female students, urban residents, high-achieving students, and senior students (Grade 12) manifest distinct advantages in terms of online self-regulated learning aptitude. Conversely, male students, rural residents, students with comparatively lower academic achievements, as well as students in Grade 10 and Grade 11, evince limitations in online self-regulated learning skills. Additionally, Moderate internet use enhances high school students' online self-regulated learning; excessive or insufficient use hampers skill development. Future research should expand the sample to diverse regions and cultures to enhance generalizability.
本研究采用问卷调查的方式，探讨了中国东隅 Y 市三所学校高中学生的在线自我调节学习技能。结果显示，高中生的网络自我调节学习能力处于中等水平，不同群体的高中生之间存在显著差异。具体来说，女生、城市居民、成绩优秀的学生和高年级学生（12 年级）在网络自我调节学习能力方面表现出明显的优势。相反，男生、农村居民、学习成绩相对较差的学生以及 10 年级和 11 年级的学生在网络自我调节学习技能方面则表现出局限性。此外，适度使用互联网能提高高中生的在线自我调节学习能力，而过度使用或不充分使用互联网则会阻碍技能的发展。未来的研究应将样本扩大到不同地区和文化，以增强普适性。

This study presents the Academic Investment Model (AIM) as a novel approach to predicting student academic performance by incorporating learning styles as a predictive feature. Utilizing data from 138 Marketing students across China, the research employs a combination of machine learning clustering methods and manual feature engineering through a four-quadrant clustering technique. The AIM model delineates student investment into four quadrants based on their time and energy commitment to academic pursuits, distinguishing between result-oriented and process-oriented investments. The findings reveal that the four-quadrant method surpasses machine learning clustering in predictive accuracy, highlighting the robustness of manual feature engineering. The study's significance lies in its potential to guide educators in designing targeted interventions and personalized learning strategies, emphasizing the importance of process-oriented assessment in education. Future research is recommended to expand the sample size and explore the integration of deep learning models for validation.

This paper provides an approach to providing QOE enhancement for a multifaceted learning platform that includes streamed media content. We demonstrate how the QOE of a multifaceted platform can be enhanced using the Lighthouse tool. The Lighthouse tool helped improve the page load speed by 75%. We also demonstrate how the playback quality of the video streaming content can be enhanced using CMAF-formatted DASH content. When compared to single-bit rate media, DASH-based media provided better video playback quality. The study also evaluates the learners` preferences for specific interactive features of a learning platform. The least preferred feature uniquely had static content. The results of this study provide empirical data that would help instructional designers make feature selection choices that`s guided by empirical data and improve the QOE of their instructional learning platforms.

This paper attempts to test and analyze students' mental health status through the reform of physical education curriculum setting mode, reveal the changes and characteristics of individual mental health status, and then promote reasonable and effective physical education reform and the integration of psychological education. Furthermore, this article investigates people's mental health using the Apriori algorithm and the BP algorithm, and accurately presents the current condition using data graphs and other approaches, and its accuracy has grown by 20.32%. It also concludes that we should pursue the aims of social adaption and mental health, as well as support improved implementation of the new physical education curriculum. Physical education instruction must be engaging, but it cannot be done in isolation from sports and practice. As part of the new curriculum reform, physical education should be linked with psychological education.

OBE concept is a new teaching mode which emphasizes the improvement of students' subjective initiative and professional practice ability. The teaching of animation course is based on drawing and computer, which requires teachers to understand the OBE mode of animation course, carry out targeted teaching innovation of animation course, and adjust the traditional teaching methods, teaching contents and teaching assessment methods. Based on the MOOC platform from the perspective of big data, this paper analyzes the teaching status and innovation process of animation course, and puts forward a hybrid animation course teaching method. Through the research of 686 primary and secondary school teachers, the results show that the hybrid animation course teaching based on OBE and MOOC from the perspective of big data has a better effect than the traditional teaching method, which improves students' initiative in learning animation courses and greatly enhances students' acceptability in learning animation courses.

Given the extensive use of online learning in educational settings, Knowledge Tracing (KT) is becoming increasingly essential. KT primarily aims to predict a student's future knowledge acquisition based on their past learning activities, thus enhancing the efficiency of student learning. However, the effective acquisition of dynamic and evolving student representations from their historical records presents a formidable challenge. This paper introduces a Knowledge Tracing methodology predicated on Dynamic Broadth Graph Convolutional Networks (DBGCN). DBGCN leverages the mechanisms of breadth graph convolutional networks to proficiently acquire representations of questions and knowledge points from dynamically constructed topological graphs. It employs student state information as an attention query vector to augment student representations, thereby partially mitigating the challenge of capturing the dynamic shifts in user states. The effectiveness of our proposed DBGCN method has been demonstrated through extensive experimentation.

Preschool education belongs to non-compulsory enlightenment education, and it is difficult to measure and analyze the development of preschool education in different regions because of its multiple attributes and diversity of influencing factors. In addition, decision makers will be limited by their own cognition when facing multi-attribute factors and uncertain factors, and there is a big gap between the decision results given and the actual situation. Therefore, this chapter introduces generalized orthogonal fuzzy sets and prospect theory into the measurement model of preschool education development level based on technique for order of preference by similarity to ideal solution (TOPSIS) method to improve the decision accuracy of decision makers. The experimental results show that the model can effectively deal with uncertain information and improve the analysis accuracy, and the results are more in line with the actual situation than other models. At the same time, it can intuitively compare and analyze the development of preschool education in different regions, and provide reliable data support for decision makers.
