2.1 The association between Teacher-Student Relationships and academic Grades
TSRs play a pivotal role in promoting positive academic outcomes for students (Taxer et al., 2019; Rooda et al., 2011). Attachment theory serves as the theoretical grounding for the role of TSRs as direct supportive mechanisms in students’ development (Ainsworth, 1989). It proposes that adult-child relationships, such as those with caregivers or teachers, bolster cognitive and self-regulatory abilities. This is partly achieved by giving children a sense of security, facilitating their exploration of the world, and helping establish an “internal working model” for interacting with attachment figures. These interactions are crucial for acquiring information and developing learning skills (Ainsworth, 1978). Therefore, students with positive relationships with their teachers can more effectively use them as a secure base and developmental asset (Pianta, 1999). As a result, these students are likelier to collaborate and engage with the teacher in classroom learning and developmental activities. They are also more inclined to persist in learning opportunities and mastering challenging tasks (Quin et al., 2017). On the other hand, students who lack a feeling of security in their relationship with a teacher may become withdrawn and disengaged from learning (Martin & Collie, 2019), or they might exhibit emotional or behavioural conflicts with the teacher (Baker et al., 2008). Improving teacher-student interactions can substantially enhance student achievement (Allen et al., 2011). Therefore, TSRs in schools can act as a promoting, safeguarding, or risk element for students in developing the essential skills and resources required for their success and well-being in school (Ansari et al., 2020).
Students spend nearly 15,000 hours in school from age five until they leave (Rutter, 1979). Their relationships with teacher can significantly impact their personal, academic and social development (Pakarinen et al., 2018). TSRs is a valuable resource for educational and developmental progress (Ansari et al., 2020). For teenage students, teachers assume a crucial role in offering valuable support, guidance, and feedback to help students navigate the intricacies of the school environment (Wentzel, 2016). Adolescents rely on the guidance and expertise of their teachers to develop academic skills, set goals, and make informed decisions about their education (Wentzel, 2016; Midgley et al., 2015). Teachers’ support and encouragement help students overcome challenges, build resilience, and develop a positive academic identity (Wentzel, 2016). Which is significantly correlated with a wide range of desirable student outcomes, such as academic achievement, emotional well-being, behaviour and motivation (Gehlbach et al., 2016). Students who experience higher levels of closeness and lower levels of conflict in their relationships with teachers tend to show more favourable outcomes (Vos et al., 2020). These positive relationships are associated with enhanced academic achievement, attendance, and motivation, as well as reduced rates of behavioural problems and dropout (Roorda et al., 2021). Conversely, poor teacher-student relationships can lead to disengagement, particularly among marginalized or trauma-affected students (Martin & Collie, 2019). Therefore, the connection between teachers and students is pivotal element in shaping the overall school environment, with a substantially influencing students’ academic outcomes and well-being (Roorda et al., 2021).
Hypothesis 1: There is a direct relationship between teacher-student relationships and students' academic grades.
2.2 The indirect role of perceived teaching quality
Teaching is widely considered an inherently stressful profession (Johnson et al., 2005). The demanding and continuously challenging nature of the teaching profession frequently results in educators experiencing emotional exhaustion (Donker et al., 2020). Teachers who are emotionally drained may find it challenging to engage and inspire their students effectively (Frenzel et al., 2021). This state may not only lead to reduced job satisfaction (Wolpin et al., 1991), but also affects the individual teacher’s well-being and thus creates a less positive learning environment for students (Milatz et al., 2015). Positive TSRs can boost teachers’ self-efficacy (Mashburn et al., 2006), and which in turn has associations with teaching quality (Burić & Kim, 2020; Holzberger et al., 2013). Teachers who establish strong and positive relationships with their students are motivated to invest additional time and effort into advancing their students’ success (Robinson, 2022).
Teaching quality is a critical factor in promoting student's achievement and educational outcomes (Smimou & Dahl, 2012). The expectations of students—specifically regarding the knowledge they acquire—are crucial for gaining a deeper insight into teaching quality (Smimou & Dahl, 2012). Perceived teaching quality encompasses numerous attributes as conceptualized by students—who may be viewed as consumers, clients, or partners in the educational process (Smimou & Dahl, 2012). Student perceived teaching quality can be argued that true quality in teaching is achieved when student satisfaction is at its peak (Rapert et al., 2004). Perceived teaching quality is positively correlated with student motivation, particularly intrinsic motivation (Dahl & K. Smimou, 2011). For teachers, strong TSRs can safeguard teachers against emotional burnout by enhancing their enjoyment and reducing feelings of anger in the classroom (Taxer et al., 2019). Teachers tend to adopt higher- quality teaching practices when they maintain positive relationships with their students (Li & Wang, 2024). When teachers have strong, positive connections with their students, they are more inclined to engage in teaching practices that require greater effort and complexity but are known to have a high impact on student learning (Li & Wang, 2024).
Positive TSRs enable educators to foster a more fulfilling and effective teaching and learning environment, benefiting teachers and their students (Jennings & Greenberg, 2009). For students, a positive TSR can enhance their learning motivation (Quin et al., 2017), and this relationship is positively related to the improvement of their academic performance (Roorda et al., 2021; Wentzel, 2016). Positive TSRs are associated with increased school engagement and achievement from preschool to high school (Roorda et al., 2011; Quin, 2017), directly and indirectly influence student academic outcomes and classroom motivation (Jowett et al., 2023). Furthermore, the link between academic grades and perceived teaching quality is intuitively logical, suggesting that students who view the quality of instruction favourably are likely to achieve better academic grades. However, this relationship requires empirical validation to establish a definitive connection. This study hypothesis that perceived teaching quality logically serves an indirect role in the relationship between TSRs and students' academic grades.
Hypothesis 2: Students' perceived teaching quality serves as an indirect mediator in the relationship between teacher-student relationships and academic grades.
2.3 The moderation role of mental health symptoms
Mental health symptoms, particularly anxiety, depression, and stress, are prevalent among students in educational settings (Meeks et al., 2021; Othman et al., 2019), these symptoms are negatively associated with academic performance (Leow et al., 2024; Lipson & Eisenberg, 2018), including lower GPAs and higher dropout rates (Eisenberg et al., 2009; Lipson & Eisenberg, 2018). Students with mental health symptoms are more likely to be dissatisfied with their academic experience and have lower academic expectations (Lipson & Eisenberg, 2018). For example, students experiencing high levels of anxiety or depressive symptoms often struggle with concentration, memory, and overall cognitive function, which are critical for learning and academic grades (Eisenberg et al., 2013). Furthermore, anxiety disorders may play a significant role in academic underachievement and increased dropout rates, influencing high school dropout rates (Ameringen et al., 2003; Brumariu et al., 2023). These students are less likely to enter or complete college (Woodward & Fergusson, 2001). Moreover, anxiety symptoms are linked to lower academic self-concept (Brumariu et al., 2023), impaired social functioning, and school refusal (de Lijster et al., 2018). The relationship between mental health symptoms and education outcomes is bidirectional (Esch et al., 2014), high levels of academic stress, which are prevalent among students, are also linked to increased levels of depression and anxiety, further impacting academic outcomes negatively (Deng et al., 2022).
Over the past ten years, progress in developmental psychopathology has highlighted the longitudinal relationships among students’ performance in academic, psychological, and social performance (Suldo et al., 2013). Mental health symptoms might significantly alter how students perceive and interact with their learning environment and teachers. For instance, a student experiencing high levels of anxiety may perceive neutral feedback from a teacher as negative or critical, which could affect their academic engagement and outcomes (Kern et al., 2017). Similarly, depression might diminish a student’s response to positive educational stimuli (e.g., teaching methods), thereby reducing the positive effects of teaching quality on academic outcomes. Although previous studies have examined the direct impact of teaching quality on academic achievement, research specifically focusing on how mental health symptoms moderate this relationship remains limited. Additionally, little is known about how students' mental health symptoms affect their perceptions of instructional quality and, subsequently, their academic grades. The importance of considering mental health symptoms as moderators is critical due to their capacity to influence students' cognitive appraisals and emotional responses (Roeser et al., 2000). Therefore, this study aims to explore whether students' mental health symptoms moderate the relationship between their perceived teaching quality and academic outcomes.
Hypothesis 3. Students' mental health symptoms moderate the strength of the relationship between perceived teaching quality and academic grades.
2.4 Current study
Previous studies underscore the importance of TSRs in educational and developmental progress (Vos et al., 2020; Gehlbach et al., 2016), highlighting their significant association with students' academic outcomes (Roorda et al., 2011). Despite this, there is still limited understanding of whether TSRs is associated with students' perceived teaching quality and academic grades. Furthermore, although correlations between mental health and academic performance are well-documented, empirical studies exploring whether students' mental health symptoms moderate the relationship between perceived teaching quality and academic grades remain limited. This study aims to address these gaps by using Structural Equation Modelling (SEM) method to explore the indirect role of perceived teaching quality in the relationship between TSRs and academic outcomes, as well as the moderating role of students' mental health status in the relationship between perceived teaching quality and academic grades. The research framework of this study refers to Figure1:
This framework positions TSRs as a foundational element that is presumed to influence students' perceptions of teaching quality. It suggests that positive and supportive teacher-student interactions might associated with students' perceptions of teaching quality. Within this framework, perceived teaching quality serves an indirect role, indicating that the quality of teaching, as perceived by students, is crucial in translating the benefits of positive TSRs into improved academic performance. Additionally, Student's mental health symptoms are served as a moderator between perceived teaching quality and academic grades. This arrangement implies that the association between perceived teaching quality and academic grades can vary based on the mental health status of the students. This framework underscores the complex interplay between emotional and educational dynamics, highlighting how both teacher-student relationships and individual student factors, such as mental health, might influence educational outcomes.
