The global prominence of English as a lingua franca has positioned English for Academic Purposes (EAP) instruction as a critical component of higher education in non-native English-speaking contexts1. In China, the Ministry of Education has consistently emphasized enhancing college English instruction to cultivate internationally competitive graduates capable of engaging with global academic discourse2. In Chinese EAP classrooms where mathematic is taught as a subject, instructors' pedagogical approaches play a fundamental role in shaping not only linguistic outcomes but also students' psychological engagement with the learning process and their overall satisfaction with educational experiences3. The relationship between teaching styles and student outcomes has garnered considerable scholarly attention over the past decades4. Research has demonstrated that teaching styles influence multiple dimensions of student experience, including cognitive engagement, emotional investment, and behavioural participation5,6. However, despite these findings, there remains a lack of clarity regarding how specific pedagogical approaches influence multiple student outcomes simultaneously within EAP contexts, particularly in Chinese higher education.
Motivation, as conceptualized within Self-Determination Theory, represents a potentially crucial mediating mechanism linking teaching styles to student engagement and satisfaction7,8. In the Chinese educational context, where traditional teacher-centered approaches have historically predominated, understanding how different teaching styles affect student motivation is particularly significant9. Academic engagement, encompassing students' active involvement, investment of effort, and psychological connection to learning activities, has been identified as a robust predictor of educational success10. Engaged students demonstrate greater persistence, employ deeper learning strategies, and achieve superior academic outcomes compared to their disengaged counterparts11. Despite extensive research on direct relationships between teaching styles and student outcomes in mathematics education, current literature lacks an integrated model that examines the mediating role of motivation in linking specific pedagogical approaches in current contexts13. Specifically, there is limited research integrating teaching styles, motivation, engagement, satisfaction, and loyalty within a single comprehensive model in EAP settings.
Furthermore, the concept of student loyalty, defined as students' intention to maintain relationships with their educational institution and to recommend it to others, has emerged as an important consideration in higher education research14. Drawing from Customer Satisfaction Theory, satisfied students are expected to demonstrate greater loyalty toward their educational providers. The present study addresses a critical gap in the existing literature, where prior research has largely examined teaching styles, motivation, academic engagement, and satisfaction in isolation or within fragmented theoretical frameworks, with limited attention to their integrative mechanisms within English for Academic Purposes (EAP) contexts in China. Despite increasing emphasis on student-centered pedagogy in EAP, there is limited empirical clarity on how teaching styles influence student engagement and satisfaction, particularly through mediating factors such as motivation in Chinese tertiary contexts. Despite increasing emphasis on student-centered pedagogy in EAP, there is limited empirical clarity on how teaching styles influence student engagement and satisfaction, particularly through mediating factors such as motivation in Chinese tertiary contexts. Therefore, the objective of this study is to examine the relationships between teaching styles, motivation, academic engagement, satisfaction, and student loyalty among Chinese EAP learners. This study advances research by simultaneously examining the mediating role of motivation in the relationships between four distinct teaching styles assertive, suggestive, collaborative, and facilitative and academic engagement, while also investigating the sequential pathway from engagement to satisfaction to loyalty. This study is novel in integrating multiple pedagogical and psychological constructs within a unified structural model in the Chinese EAP context. By offering a holistic model that captures both pedagogical antecedents and outcome pathways, this research provides these relationships within Chinese tertiary mathematics education, offering fresh insights into how assertive, suggestive, collaborative, and facilitative teaching styles drive student engagement, satisfaction, and loyalty through motivational pathways, thereby extending theoretical integration and empirical evidence in the field.

The educational experiences of EFL learners are strongly shaped by teachers’ teaching styles. Drawing on teaching style models, this study examines how teachers’ strategies influence students. As shown in Table 1, different teaching styles can affect learners’ motivation and engagement in different ways. In higher education, motivation and academic engagement are often strengthened by supportive teachers, respectful classroom relationships15, and positive peer interaction16. Teaching styles that promote learning, build confidence, and support language development are therefore essential for successful language learning17,18. In addition, pedagogical practices, technology integration, lesson planning, and instructional integrity can further influence students’ motivation in English language classes19. HA1: EFL teachers’ teaching styles significantly affect different dimensions of Chinese EFL students’ motivation at the tertiary level.

Extensive research has examined factors that motivate language learning; consequently, motivation is an essential construct that affects all stages of language learning at the higher education level24,25. Students must remain actively engaged in class to feel motivated; hence, there is a motivation to foster more effective classroom participation26. In addition to this, teachers possess extraordinary power by connecting with students and leading their teaching style in favour of better learning and mastery of the topic27. Hence, when teachers fail to engage their students academically, they do not motivate them28. Thus, the process proves fruitless. Motivation in treating the SLL process is crucial, and engaging our EFL learners in higher education is pivotal29. HA2: EFL mathematic Chinese students’ motivation impacts their academic engagement at the tertiary level.
Students who demonstrate strong engagement and high self-efficacy in the classroom tend to manage their time effectively, perform well academically30, complete their studies, and actively participate in a variety of activities31. This involvement not only enhances their academic experience but also allows them to enjoy the learning process and derive satisfaction from tackling tasks32. According to the theory of success, high self-efficacy and active classroom participation lead students to view their academic goals as attainable33. As a result, their attitudes towards mastering English become increasingly positive, and their level of engagement intensifies34. Students’ academic confidence, participation, and satisfaction are interconnected, and this linkage enhances the likelihood of academic success and a more positive academic experience35. However, lower academic self-efficacy may diminish engagement, leading to failure36,37. In line with this, previous empirical studies have consistently found a strong influence of student self-efficacy on academic engagement38. HA3: EFL mathematic Chinese students’ academic self-efficacy significantly impacts their academic engagement.
The success and effectiveness of both students and universities are closely linked to student satisfaction and academic achievement, as these institutions aim to motivate and meet students' needs39. However, prioritizing higher levels of student engagement is crucial to fostering both academic success and satisfaction40. Student motivation and satisfaction are essential components of academic success, underscoring the need for teachers to actively engage students in classroom activities to meet their academic and personal needs41,42. Explored the role of institutional infrastructure, focusing on factors such as sports facilities, accommodation, and transportation systems, in influencing student satisfaction43,44. Sports and transportation have a significant positive relationship with student satisfaction, whereas accommodation has a minimal and insignificant impact on academic performance and satisfaction45,46. HA4: EFL mathematic Chinese students’ academic engagement significantly impacts their satisfaction at the tertiary level.
Students’ satisfaction is influenced by a range of personal and institutional factors, making it a multi-dimensional construct47. The quality of instructors, well-structured lesson plans, timely feedback, resource accessibility, and effective use of technology significantly affect students' satisfaction and sense of connection with the institution48. Besides that, teaching ability, flexible behaviour, the prestige and the status of the university/college too are the key factors that can form a happy and loyal student at higher education level49. The objective of this study is to evaluate how different teaching styles influence student motivation and academic engagement among Chinese EAP learners using a structural equation modelling framework. HA5: EFL mathematic Chinese students’ satisfaction significantly impacts their loyalty at the tertiary level. HA6: EFL mathematic Chinese students’ motivation mediates the relationship between EFL teachers’ teaching style and students’ academic engagement.

The novelty of this study lies in its integrated examination of how four distinct teaching styles assertive, suggestive, collaborative, and facilitative shape Chinese tertiary EFL learners’ motivation, academic engagement, satisfaction, and loyalty within a single structural model. Unlike prior studies that have typically focused on isolated or direct relationships, this research highlights the mediating role of motivation and the sequential pathway from engagement to satisfaction and loyalty, thereby offering a more comprehensive explanation of how pedagogical approaches influence student outcomes in higher education. In doing so, the study makes a unique theoretical and practical contribution by combining multiple frameworks and providing context-specific evidence for Chinese university classrooms.
