Previous research on perceived teacher support has mostly used a variable-centered approach, ignoring the existence of different profiles of perceived teacher support and possible differences in their associations with other factors. Focusing on a person-centered approach, this study used LPA to examine students’ different perceived teacher support profiles and explored whether gender and grade predict the probability of student profiles. In addition, the study examined the relationships and underlying mechanisms between different perceived teacher support profiles and mathematics learning factors.
6.2 RQ2: Gender, grade, and latent profiles of perceived teacher support
The results show that there are no significant differences in perceived teacher support across different profiles based on gender and grade. Gender and grade did not predict the different potential profile probabilities of perceived teacher support. Although this result is inconsistent with the expectations of the gender socialization hypothesis and the vulnerability hypothesis [25, 26], it aligns with research suggesting the consistency of perceived teacher support across genders [27, 65]. One possible explanation for this result is the increasing emphasis on gender equality and the evolution of educational practices, which encourage teachers to treat all students equitably and reduce gender bias. This may lead to students perceiving teacher support as more gender-neutral [27, 65]. At the same time, students become more gender-conscious and focus more on internal needs than external stereotypes, further weakening the impact of gender on perceived teacher support[66].
The influence of grade level is inconsistent with the results of previous studies, showing no significant difference in perceived teacher support profiles. The reason may lie in the current educational practice and cultural background. First, the modern education system emphasizes continuity, so that different grades maintain stable educational environments, goals, content, and methods, which may allow students to maintain relatively consistent learning experiences and support from mathematics teachers [67]. Second, education reforms promote the professional development of teachers and ensure that mathematics teachers at all grades provide stable support [68]. In addition, students adapt to school life as they grow older, forming stable learning attitudes and emotions, which further stabilizes their perceived teacher support [22].
6.3 RQ3: The three latent profiles of perceived teacher support and mathematics engagement, mathematics attitude, and mathematics anxiety
Current research shows that students with different perceived teacher support profiles have significant differences in their mathematics engagement. Specifically, mathematics engagement increases progressively across students with low, medium, and high perceived teacher support. Further analysis revealed students with high perceived teacher support showed significantly higher overall mathematics engagement, encompassing elevated levels of behavioral, cognitive, and emotional engagement in mathematics learning. This finding aligns with self-determination theory which suggests that supportive teacher relationships enhance student engagement in learning. When teachers provide clear guidance, timely feedback, and emotional support, students’ interest in mathematics can be enhanced, and their needs for learning autonomy and ability can be satisfied, thus comprehensively promoting engagement in mathematics learning [15, 17]. This finding is also consistent with previous variable-centered studies, that is, students’ high perceived teacher support is positively correlated with their mathematics engagement, which highlights the core role of teacher support in students’ mathematics engagement [2, 17, 33]. Our research further confirms the person-centered perspective that there is a positive association between different perceived teacher support profiles and mathematics engagement. This finding highlights the importance of perceived teacher support for student mathematics engagement and provides a new perspective for understanding the increase in student mathematics engagement.
The results of this study reveal significant differences in mathematics anxiety among students with different perceived teacher support profiles, in line with previous variable-centered research. Specifically, students with high perceived teacher support exhibit lower levels of mathematics anxiety [3, 38]. Perceived teacher support can significantly enhance students’ confidence in mathematics, thus effectively reducing mathematics anxiety [3, 33, 38]. Further analysis showed that different teacher support profiles had significant differences in influencing students’ classroom anxiety. Students with high perceived teacher support had the lowest levels of anxiety in the classroom [3, 21, 69]. However, this study did not find significant differences between problem-solving anxiety and test anxiety. This may be due to the high difficulty and complexity of high school mathematics [1]. Even if students feel supported by their teachers, they still face great pressure when solving problems and taking exams. Therefore, this study suggests that while improving teacher support to alleviate students’ classroom anxiety, we should also pay attention to two more complex and multi-dimensional areas, namely problem-solving anxiety and test anxiety. Therefore, this study suggests that while improving teacher support to alleviate students’ classroom anxiety, we should also pay attention to two more complex and multi-dimensional areas, namely problem-solving anxiety and test anxiety.
The study also found significant differences in mathematics attitudes among students with different perceived teacher support profiles. Further analysis that there were significant differences in learning motivation and learning strategies. Consistent with previous variable-centered studies, students with higher levels of perceived teacher support demonstrated more positive attitudes toward mathematics. Additionally, these students demonstrated significantly enhanced learning motivation, proactively exploring learning opportunities and showing a willingness to overcome challenges [50]. They show higher self-regulation ability in learning strategies and can flexibly adjust methods to optimize learning effects [20, 70]. However, no significant differences were found in learning beliefs, which may be because students’ inherent beliefs are stable and not susceptible to fluctuations by external factors such as teacher support [71].
6.4 RQ4: Mechanisms between the three latent profiles of perceived teacher support and mathematics engagement, mathematics anxiety, and mathematics attitude
Regarding mathematics attitudes, the research revealed a close relationship between teacher support and students’ attitudes toward mathematics. Specifically, moderate to high levels of perceived teacher support had a significant positive impact on students’ mathematics attitudes. Students who feel supported by their teachers show greater confidence, strong interest, sustained enthusiasm, and more positive attitudes in mathematics learning [46, 72]. Further analysis revealed the key mediating role of mathematics attitude between teacher support and mathematics engagement. This means that by providing support, teachers can improve students’ mathematical attitudes, which in turn promotes their more active engagement in mathematical learning activities [22, 49, 50]. This finding highlights the role of mathematical attitudes as a bridge between teacher support and mathematics engagement.
When examining the mediating effect of mathematics anxiety, the findings showed an interesting pattern: moderate perceived teacher support had no significant effect on mathematics anxiety, while high perceived teacher support significantly reduced it. This suggests that mathematics anxiety can only be effectively alleviated when students feel adequately supported by their teachers [3, 73]. It is worth noting that mathematics anxiety has been theoretically and empirically explained to have an impact on mathematics engagement [18, 34]. However, in this study, it did not show this predicted effect. This is mainly attributed to the following two reasons: on the one hand, mathematics attitude plays a dominant role in the mediation model, and its positive influence may cover up the potential interference of mathematics anxiety; on the other hand, there may be potential interaction effects between teacher support and mathematics anxiety. In this study, even though higher anxiety levels were prevalent among the student population, this phenomenon did not significantly affect mathematics engagement, possibly because teacher support became an effective moderator. Specifically, teacher support may effectively alleviate students’ anxiety about mathematics through frequent support and assistance to learners, thereby weakening the negative impact of anxiety on mathematics engagement.
