To enhance teacher professional development, this study devises a moderation model, informed by two empirical investigations, which examines the impact of appropriate teacher discipline on teacher trust and explores the moderating role of teacher caring within this context. Methods Two questionnaires were conducted among 463 junior high school students in China. Results The findings show that: (1) proper teacher discipline significantly predicts teacher trustworthiness and trust; (2) teacher care significantly predicts teacher trustworthiness; and (3) for rural children, teacher care has a significant moderating effect on teacher trustworthiness. Conclusions The proper use of teacher punishment has a good impact on middle school students' faith in teachers, and gradually increasing the amount of teacher care may become a strategy to compensate for the losses produced by ineffective teacher discipline.

Disciplinary appropriateness Teacher care Trust Trustworthiness Figures Figure 1 Figure 2 Figure 3 Figure 4 Background In interpersonal relationships, trust is the cornerstone for making connections. In social interactions, people assess the trustworthiness of others by examining a variety of cues before determining whether to trust them [ 1 ]. According to research, the intensity of third-party punishment can influence observers' trustworthiness judgments and trust behavior toward the punisher [ 2 ]. Punishment is not the only method for restoring justice [ 3 ]. When society has already reached a point of cooperation, placing too much focus on punishment can result in higher societal losses [ 4 ]. However, this viewpoint fails to adequately address deservedness as a key component of signal content, limiting the potential range of punishment harshness [ 5 ]. The trustworthiness of teachers, as a precursor variable to student trust, is an important factor influencing the quality of the teacher-student relationship. However, research on how trust emerges remains limited [ 6 ]. Existing literature often emphasizes that teachers are a key factor influencing student satisfaction and retention rates [ 7 , 8 ]. As significant figures in students' educational journeys, teachers play an essential role in fostering students' positive development. Moreover, teachers are widely regarded as the most crucial component of any educational system [ 9 ]. Abusive punishment can undermine the effectiveness of altruistic punishment in maintaining social norms [ 10 ], whereas non-deterrent restorative interventions may have unexpectedly positive effects on maintaining these norms [ 11 ]. As key stakeholders in the education system, teachers have been found to significantly influence both the effectiveness of the system and students' academic performance [ 12 ]. Most teachers strive to be perceived as fair by their students, as this perception can prevent negative reactions and foster a more positive learning environment. Teacher punishment appropriateness and trust In daily teaching, educators often face the challenging task of delivering negative messages or critical feedback to students, a necessity for effective education [ 13 ]. Additionally, teachers must enforce school regulations by punishing violators in a manner that reflects the severity of the infraction, all while maintaining effective classroom management. The severity of punishment should be proportionate to the wrongdoing [ 14 ], however, punitive interventions, which serve as external motivators, can have a dual effect: they may promote short-term compliance with norms, but they can also erode interpersonal trust and supplant individuals' internal motivation to adhere to norms, potentially leading to a swift resurgence of undesirable behavior once the punitive measures are removed [ 15 ]. Teachers who exhibit unprofessional behavior in the classroom [ 16 ] and display high levels of verbal aggression are often perceived as less credible by their students [ 17 ]. When students view their course grades, course procedures, or teacher communication as unfair, they are more likely to engage in indirect attacks on the teacher [ 18 ]. Consequently, it is hypothesized that appropriate punishment can foster trust, whereas inappropriate punishment can erode it (Hypothesis 1). The mediating role of trustworthiness Trustworthiness is assessed based on the presence or absence of motivation to deceive. According to Mayer et al. [ 19 ], the comprehensive ABI model distinguishes the structural components of trustworthiness (ability, benevolence, and integrity) from the perceived factors that contribute to trust. The fairness heuristic theory suggests that fairness plays a significant role in the formation of trustworthiness [ 20 ], and the appropriateness of a punishment indirectly reflects whether the punisher possesses fair traits. Third-party punishment enables punishers to signal qualities such as trustworthiness, and imposing sanctions in response to violations can enhance the punisher's reputation, indicating that they are fair and trustworthy [ 21 ]. In comparison to non-punishers, third-party punishers are more trusted and exhibit more trustworthy behavior. Trustworthiness is a strong predictor of an individual's trust in leaders, teachers, or managers [ 22 ]. Research in higher education has shown that competence, kindness, and integrity directly influence students' trust in professors, rather than serving as prerequisites for such trust [ 23 ]. In this process, individuals form trust in authority based on their perceptions of the authority's trustworthiness, which provides a clearer explanation for why one person might trust another. It is proposed that trustworthiness mediates the relationship between the appropriateness of teacher discipline and students' trust in teachers, suggesting that a teacher's trustworthiness plays a crucial role in fostering trust (Hypothesis 2). The moderating effect of teacher care A positive correlation exists between teacher trustworthiness and students' behavioral tendencies, encompassing out-of-class interactions, participation in class discussions [ 24 ], teacher evaluations, and cognitive-emotional learning outcomes [ 25 ]. The constructs of teacher resilience, buoyancy, and care have been found to significantly influence student engagement [ 26 ]. However, the predictive potential of "teacher care" as a variable in fostering positive interpersonal relationships has been relatively underexamined [ 27 ]. To establish strong relationships, teachers must understand their learners, demonstrate care for their needs, and respect their perspectives. In addition to teaching and learning issues, teachers bring their own value systems, beliefs, mindsets, and behaviors into the classroom, which can indirectly influence learners. Teachers who prioritize students' well-being can instill trust, encouraging enthusiastic engagement in the classroom environment [ 28 ]. By establishing close connections with students, teachers can create a comfortable and supportive learning environment, facilitating safe communication within the classroom [ 29 ]. Caring teachers can foster a trustworthy learning atmosphere, making students more inclined to participate in learning activities. A warm and friendly teacher-learner relationship can significantly enhance learners' willingness to communicate [ 30 ], reduce dropout rates [ 31 ], and foster positive teacher-student rapport, encouraging active interaction with teachers and classmates [ 32 ]. Therefore, we propose that teacher care plays a moderating role in the relationship between the appropriateness of discipline and teacher trustworthiness (Hypothesis 3). This study, grounded in prior research, investigates the relationship between teacher punishment appropriateness and student trust among adolescents, employing a moderated mediation model to elucidate the underlying mechanisms. Method Study 1 Participant A junior high school in Henan Province, China, was selected for this study, and 243 questionnaires were distributed using cluster sampling, yielding 224 valid responses (92.2% response rate). The sample consisted of 111 males (49.55%) and 113 females (50.45%). Among them, the proportion of poor grades is 6.25%, the proportion of below-average grades is 20.09%, the proportion of average grades is 32.59%, the proportion of above-average grades is 29.91%, and the proportion of excellent grades is 11.16%. Experimental Design and Procedure Participants completed paper questionnaires, which included measures of personal basic information (grade, age, and academic performance), followed by scales assessing teacher care, disciplinary appropriateness, trustworthiness, and trust. The independent variable was teacher discipline appropriateness, the moderating variable was teacher care, the mediating variable was trustworthiness, and the dependent variable was trust. Experimental Materials and Tools Disciplinary Appropriateness Scale This scale, adapted from [ 33 ], assessed adolescents' perceptions of teacher disciplinary appropriateness. The 3-item scale utilized a 5-point Likert scale (1 = complete disagreement, 5 = complete agreement), with higher scores indicating greater perceived appropriateness. The Cronbach's α for this scale was 0.81. Trustworthiness Scale Based on Brockner et al. [ 34 ], this 3-item scale measured teacher trustworthiness using a 5-point Likert scale (1 = strong disagreement, 5 = strong agreement). Higher scores indicated greater trustworthiness. The Cronbach's α for this subscale was 0.72. Trust Scale The 6-item trust scale, developed by Jing et al.[ 35 ], employed a 5-point Likert scale (1 = strong disagreement, 5 = strong agreement). Higher scores reflected greater trust in teachers. The Cronbach's α for this scale was 0.77. Care Scale The Teacher Care Scale, developed by Teven and McCroskey [ 36 ], consisted of 10 items assessing teacher care. Representative items included "values my interests" and "understands my feelings." The 7-point Likert scale (1 = completely disagree, 7 = completely agree) was used, with higher scores indicating greater teacher care. The Cronbach's α for this scale was 0.80. Results Common Method Bias Test To mitigate common method bias, participants were assured of questionnaire anonymity and confidentiality, and informed that data would be used exclusively for research purposes. Furthermore, Harman's single-factor test was conducted to assess common method bias. The results yielded six factors with eigenvalues greater than 1, with the first factor accounting for 31.88% of the variance, below the 40% critical threshold. This suggests that common method bias is unlikely to be a significant concern. Correlation Analysis Between Variables Table 1 presents the means, standard deviations, and correlation coefficients for each variable. The results reveal significant positive correlations between pairs of variables, including teacher discipline appropriateness, care, trustworthiness, and trust. Table 1 Descriptive Statistics and Correlation Analysis Results ( N = 224) Variables M ± SD 1 2 3 4 Discipline appropriateness 4.14 ± 0.90 1 Teacher care 4.99 ± 0.88 0.47 *** 1 Trustworthiness 3.52 ± 0.57 0.40 *** 0.41 *** 1 Trust 4.12 ± 0.73 0.46 *** 0.57 *** 0.57 *** 1 Note: Disciplinary appropriateness = 1, Teacher care = 2, Trustworthiness = 3, Trust = 4; * represents p < 0.05, ** represents p < 0.01, *** represents p < 0.001. similarly hereinafter. The mediating role of trustworthiness and the moderating role of teacher care Using Model 4 in the PROCESS macro, we examined the mediating effect of trustworthiness on the relationship between discipline appropriateness and trust, controlling for students' gender, age, and grades. The results indicate that discipline appropriateness significantly and positively predicts trust ( β = 0.40, p < 0.001). Furthermore, discipline appropriateness positively predicts trustworthiness ( β = 0.41, p < 0.001), which in turn positively predicts trust ( β = 0.41, p < 0.001). The bias-corrected percentile Bootstrap method test revealed a significant direct effect (0.40, 95% CI = [0.29, 0.51]) and a significant mediating effect of trustworthiness (0.17, 95% CI = [0.09, 0.26]), accounting for 29.83% of the total effect.

The results (Table 2 ) show that teacher care significantly predicts trustworthiness ( β = 0.26, p < 0.001). However, the interaction term between discipline appropriateness and teacher care does not significantly predict trustworthiness ( β = -0.06, p = 0.28), the model diagram is shown in Fig. 1 . Brief summary This exploratory study provides a foundational framework for examining the impact of teacher disciplinary appropriateness on trust. However, several limitations warrant further investigation. The reliance on self-reported data from subjects introduces potential subjective bias and social desirability bias, which may compromise the objectivity and generalizability of the findings. Furthermore, the non-significant moderating effect of teacher care on the relationships between variables suggests that this factor may not play a crucial role in this context. This outcome may be attributed to various factors, including sample characteristics, measurement tools, and cultural background. To address this, follow-up studies should investigate the regulatory role of teacher care in greater depth. Additionally, the study's sample is limited to urban middle school students, whereas the education of rural left-behind children has significant implications for human capital accumulation and economic growth. Therefore, it is essential to replicate and extend the research to rural middle school students to enhance the generalizability and applicability of the findings. Study 2 Participant To reach 80% (1-β) statistical power, the study required at least 159 subjects, as assessed by G*Power 3.1.The experiment chose a township middle school in Henan Province, China, and utilized a cluster sampling approach to disseminate 260 surveys, yielding 239 valid questionnaires and a recovery rate of 91.92%. Among the respondents, 124 were male (51.88%), while 115 were female (48.12%).There are 15.90% of students with poor grades, 23.85% with below-average grades, 36.40% with average grades, 19.25% with above-average ratings, and 4.60% with excellent marks. Research Design and Procedures First, the participants need to complete the demographic variables, including gender, age, and academic performance. Secondly, the subjects need to undergo manipulation of the appropriateness of teacher care and discipline. For example, in the group with appropriate care and discipline, the subjects will read the following description: " The homeroom teacher is a kind teacher who often smiles in class, He frequently takes the initiative to ask students if they need help and can remembers all the students' names. When students are having a class discussion, he joins the discussions with the students. One afternoon, the homeroom teacher was teaching a class, and A was either whispering with others or deliberately interrupting the teacher, making other students laugh and disrupting the normal class. So, the homeroom teacher asked A to clean the blackboard for the class after the lesson. Next, the participants need to answer four questions to test whether they have successfully understood the situation, such as "Did A violate class discipline?" This serves as a screening criterion, and questionnaires that do not correctly understand the situation or are not answered seriously will be eliminated. Finally, the participants need to complete the measurement of teacher trustworthiness and trust. All participants completed the experiment through paper questionnaires. Study Materials and Tools Educational punishment and care situation Referring to the scenario questionnaire designed by Teven [ 37 ], we constructed scenarios with differences in the appropriateness of teacher discipline and teacher care. To control the impact of information volume, the experimental materials were balanced, with equivalent words, sentences, and structures under different conditions. The specific context is as follows: The homeroom teacher is a kind/serious teacher who often wears a smile/doesn't smile in class. He frequently takes the initiative/doesn't take the initiative to ask students if they need help and can remember all the students' names/can't remember some students' names well . When students are having class discussions, he joins the discussions with the students/he doesn't join the discussions with the students . One afternoon, the homeroom teacher was teaching a class and A was either whispering with others or deliberately interrupting the teacher, making other students laugh and disrupting the normal class. So, the homeroom teacher asked A to clean the blackboard for the class after the lesson/call the parents in for a talk . Trustworthiness Scale The trustworthiness of teachers was assessed using Hiatt's [ 38 ] trustworthiness scale, which comprises 14 items. This scale employs a 7-point Likert scale, with responses ranging from 1 (completely disagree) to 7 (completely agree). A higher score on this scale indicates greater perceived trustworthiness of the teacher. The internal consistency of this scale, as measured by Cronbach's α, was found to be 0.85 in the present study, suggesting good reliability. Trust Scale Trust towards teachers was evaluated using the trust scale developed by Zhang and Qi [ 39 ], which consists of 3 items. This scale utilizes a 5-point Likert scale, with responses ranging from 1 (strong disagreement) to 5 (strong agreement). Higher scores on this scale reflect greater trust in the teacher. The Cronbach's α for this scale was 0.66, indicating moderate reliability in the context of this study. Research Results Manipulation Check In this study, four questions were set up to test the validity of the test questions. The four questions are respectively: What kind of person do you think the homeroom teacher is? Do you think the homeroom teacher will care about the students? Did A violate the class discipline? Do you think the homeroom teacher's punishment is appropriate? As used as a screening criterion, questionnaires that did not correctly understand the situation or did not answer carefully were removed. Correlation analysis among the variables Table 3 shows the mean, standard deviation and correlation coefficients of each variable, and the results showed a significant positive correlation between all variables except for teacher care and disciplinary appropriateness. Table 3 Correlations among the various variables Variable M ± SD 1 2 3 4 Disciplinary appropriateness 0.50 ± 0.50 1 Teacher care 0.49 ± 0.50 -0.02 1 Trustworthiness 3.74 ± 0.64 0.36 *** 0.47 *** 1 Trust 2.44 ± 0.96 0.30 *** 0.20 ** 0.45 *** 1 Moderating Effects and Variance Analysis First, look at the direct impacts of appropriate punishment on trust and trustworthiness. After adjusting for age, gender, and academic performance, the study found that appropriate punishment has a substantial direct influence on trustworthiness ( β = 0.37, p < 0.001) and trust ( β = 0.17, p < 0.01).Then, using the direct effects, trustworthiness was introduced as a mediating variable while controlling for age, gender, and grades. The direct effects of appropriate punishment on trustworthiness and trust continue to be important; appropriate punishment can strongly predict trustworthiness. Trustworthiness also greatly predicts trust. The bootstrap test findings suggest that the mediating effect of trustworthiness is 0.14, 95%CI = [0.08, 0.20]. The mediating effect accounts for 47% of total effect, the model diagram is shown in Fig. 2 . Conducting a 2×2 multifactorial ANOVA with trustworthiness as the dependent variable, the results show that the main effect of the appropriateness of teacher discipline is significant, F (1, 234) = 36.05, p < 0.001, η p 2 = 0.13, Middle school students rated the trustworthiness of teachers who administered inappropriate discipline ( M = 3.51, SD = 0.65) significantly lower than that of teachers who administered appropriate discipline ( M = 3.96, SD = 0.55); the main effect of teacher care was significant, F (1, 234) = 65.81, p < 0.001, η p 2 = 0.22, middle school students' trust ratings for low-care teachers ( M = 3.45, SD = 0.67) were significantly lower than those for high-care teachers ( M = 4.04, SD = 0.45).The interaction between the appropriateness of educational discipline and teacher care on trustworthiness is significant, F (1, 232) = 22.75, p < 0.001, η p 2 = 0.09. Further simple effects analysis results show that teachers with low care and inappropriate discipline have lower trustworthiness than teachers with high care and inappropriate discipline. F (1, 232) = 73.75, p < 0.001, η p 2 = 0.24, 95%CI = [-0.95, -0.59] (see Fig. 2 ); however, this effect does not exist under the high care condition, F (1, 232) = 2.66, p = 0.10. Figure 3 displays the results. Further simple slope analysis( Fig. 4 ) indicates that among teachers with lower levels of care, the appropriateness of discipline has a significant predictive effect on trustworthiness, with middle school students giving higher trustworthiness ratings; however, for teachers with higher levels of care, the predictive effect of discipline appropriateness is not significant, the detailed information is shown in Table 4 .

The results of Study 2 confirmed the moderating role of teacher care between the appropriateness and trustworthiness of punishment, indicating that teacher care indeed influences students' perception and acceptance of punishment. This finding holds significant implications for educational practice, emphasizing that teachers need to consider students' feelings and needs when maintaining classroom order and implementing punitive measures, thereby enhancing the effectiveness of punishment through the demonstration of teacher care. Moreover, Study 2 specifically focused on a sample of rural middle school students for further exploration. This approach helps to address the shortcomings in sample representativeness of previous studies, as rural students may face different educational environments and challenges compared to urban students. Discussion This study investigated the relationship between the appropriateness of teacher punishment for adolescents and their trust in teachers, as well as the potential mechanisms underlying this relationship. The results indicated that the appropriateness of teacher punishment can positively predict teacher trustworthiness and trust, with trustworthiness acting as a mediator. Specifically for rural children, teacher care can exert a highly effective influence. Teachers' disciplinary appropriateness and the trust of teachers The study's findings revealed that the more appropriate the teacher's punishment, the more students perceived the teacher as trustworthy. Adolescent students are also concerned with the fairness of teacher punishment and accordingly adjust their trust in the punisher. This is consistent with previous research, which indicates that punishment not only has a direct impact on the responsible party and those affected but also has a ripple effect on observers. The effectiveness of punitive interventions depends on their legitimacy. When punishment is misused, it not only fails to effectively maintain norms but also undermines the positive effects of legitimate punishment, leading to a decline in the level of group cooperation [ 40 , 41 ]. The mediating role of trustworthiness The present study found that trustworthiness plays a mediating role in the relationship between the appropriateness of teacher punishment and students' trust in teachers. The more appropriate the teacher's punishment, the more likely junior high school students are to perceive the teacher as trustworthy, thereby eliciting a higher level of trust. Conversely, compared to appropriate punishment, inappropriate punishment has a detrimental impact on junior high school students' perception of trustworthiness, ultimately leading to a decrease in trust. Therefore, teachers' appropriate use of punishment can enhance their trustworthiness and foster trust, while inappropriate punishment can diminish their trustworthiness and undermine students' trust in them. The Moderating Role of Teacher Care This study elucidates the moderating effect of teacher care in constructing the relationship between teacher trustworthiness and the appropriateness of teacher punishment. When punitive measures are inappropriate, caring behaviors by teachers can effectively mitigate the negative impacts arising from such misjudged punishment, thereby safeguarding the teachers' trustworthy image in the eyes of students. The presence of emotional support from teachers can assist students in establishing positive teacher-student relationships, enhancing students' sense of security and belonging, and consequently boosting their trust in teachers. However, as the appropriateness of teacher punishment increases, the mitigating effect of teacher care on students' sense of trust gradually diminishes. This suggests that when teachers' punitive actions are just, reasonable, and in line with students' expectations, students' trust in teachers relies on the teachers' integrity rather than excessively on their care. Therefore, when implementing punishment, a just and upright image of teachers is more capable of enhancing students' evaluation of their trustworthiness. It is noteworthy that a higher level of teacher care is not always better. There exists a threshold for the level of teacher care; once this threshold is exceeded, the growth in perceived trustworthiness of teachers will become sluggish. In contrast, for urban children, high care has a positive effect on rural children, with teachers who are punitive but caring receiving higher ratings than those who are appropriately punitive but less caring. For rural children, who often live apart from their parents and are primarily cared for by grandparents or other elderly relatives, intergenerational care constitutes the predominant parenting model in left-behind children's families. The grandparents or other elderly caregivers of these rural left-behind children generally have lower levels of education, with many being illiterate, leading to a relative lack of parental love and education. This results in most left-behind children developing sensitive, introverted, and even inferior personality traits, lacking familial affection in their emotional and psychological well-being. Meanwhile, the implementation of effective emotional care strategies by homeroom teachers can yield immediate and highly efficient outcomes. Thus, it is evident that the level of teacher care and the manner of punishment have complex impacts on their perceived trustworthiness. Teachers need to strike a balance between an appropriate level of care and proper punitive methods to foster students' trust and respect towards them. Educational advice Punishment, as a means of behavioral correction and discipline maintenance, plays a vital role in the educational process. However, the implementation of punishment must be founded on the principle of justice to ensure the protection of students' rights and dignity. To achieve a well-ordered and benevolent governance in educational justice, a just and virtuous "good system" is inevitably required. Educational punishment is an educational method and an expression of teachers' care for students' development and growth. Yet, whether teachers truly care for students depends not only on the teachers' willingness and actions to care but also on students' perception of these caring behaviors. In the realm of educational practice, educational justice should be embodied in an educational system with the spirit of good values as its soul, serving as an effective tool for educational governance. Schools should establish and publicize clear behavioral norms and standards of punishment, ensuring that students understand which behaviors are permitted and which are prohibited. The implementation of punishment should follow a reasonable procedure, including informing students in advance of the impropriety of their actions, listening to their defenses, and making fair decisions based on evidence and circumstances. During the punishment process, students' rights and dignity should be fully respected, and the use of corporal punishment, humiliation, or other inhumane punitive measures should be avoided. For students who exhibit inappropriate behavior, teachers should provide appropriate guidance and support to help them recognize their mistakes, correct their behavior, and get back on track. Schools should regularly evaluate the effectiveness of punishment, checking whether it has achieved the intended goals and adjusting as necessary. Teachers and administrators should maintain open communication with students, parents, and other educators, collecting their feedback and suggestions on punishment and educational care. Based on the evaluation results and feedback, schools should continuously improve their punitive mechanisms and educational care strategies to ensure that they are just, effective, and supportive. Conclusions and Limitations Conclusion This paper explores the role of teacher care between the appropriateness of teacher punishment and teacher credibility, as well as the mediating effect of credibility, through two studies. The results indicate that the appropriateness of teacher punishment significantly impacts teacher credibility and trust; the level of teacher care and the manner of punishment have complex effects on credibility, with teacher care having boundary constraints. When these constraints are exceeded, the interactive effect of appropriateness of punishment and care disappears. For rural children, teacher care demonstrates a more significant role. Limitations The current study has several limitations. Firstly, the data collected are cross-sectional. The impact of the appropriateness of teacher punishment and care on teacher trust occurs over the course of long-term interactions. A longitudinal tracking design would more accurately depict this process. Secondly, the participants in this study were Chinese middle school students. Future research could expand the participant pool to examine differences among students of various age groups and from different provinces and cultural contexts. Lastly, the influence of social norms on individual behavior is a complex cognitive processing mechanism. This paper primarily investigates the significance of the appropriateness of teacher punishment and care for student misconduct, as well as the development of trust. It does not examine the many influencing factors in this process. Identifying and controlling these factors is an important direction for future research.

In social interactions, people assess the trustworthiness of others by examining a variety of cues before determining whether to trust them [\u003cspan citationid=\"CR1\" class=\"CitationRef\"\u003e1\u003c/span\u003e]. According to research, the intensity of third-party punishment can influence observers' trustworthiness judgments and trust behavior toward the punisher [\u003cspan citationid=\"CR2\" class=\"CitationRef\"\u003e2\u003c/span\u003e]. Punishment is not the only method for restoring justice [\u003cspan citationid=\"CR3\" class=\"CitationRef\"\u003e3\u003c/span\u003e]. When society has already reached a point of cooperation, placing too much focus on punishment can result in higher societal losses [\u003cspan citationid=\"CR4\" class=\"CitationRef\"\u003e4\u003c/span\u003e]. However, this viewpoint fails to adequately address deservedness as a key component of signal content, limiting the potential range of punishment harshness [\u003cspan citationid=\"CR5\" class=\"CitationRef\"\u003e5\u003c/span\u003e]. The trustworthiness of teachers, as a precursor variable to student trust, is an important factor influencing the quality of the teacher-student relationship. However, research on how trust emerges remains limited [\u003cspan citationid=\"CR6\" class=\"CitationRef\"\u003e6\u003c/span\u003e].\u003c/p\u003e \u003cp\u003eExisting literature often emphasizes that teachers are a key factor influencing student satisfaction and retention rates [\u003cspan citationid=\"CR7\" class=\"CitationRef\"\u003e7\u003c/span\u003e, \u003cspan citationid=\"CR8\" class=\"CitationRef\"\u003e8\u003c/span\u003e]. As significant figures in students' educational journeys, teachers play an essential role in fostering students' positive development. Moreover, teachers are widely regarded as the most crucial component of any educational system [\u003cspan citationid=\"CR9\" class=\"CitationRef\"\u003e9\u003c/span\u003e]. Abusive punishment can undermine the effectiveness of altruistic punishment in maintaining social norms [\u003cspan citationid=\"CR10\" class=\"CitationRef\"\u003e10\u003c/span\u003e], whereas non-deterrent restorative interventions may have unexpectedly positive effects on maintaining these norms [\u003cspan citationid=\"CR11\" class=\"CitationRef\"\u003e11\u003c/span\u003e]. As key stakeholders in the education system, teachers have been found to significantly influence both the effectiveness of the system and students' academic performance [\u003cspan citationid=\"CR12\" class=\"CitationRef\"\u003e12\u003c/span\u003e]. Most teachers strive to be perceived as fair by their students, as this perception can prevent negative reactions and foster a more positive learning environment.\u003c/p\u003e\n\u003ch3\u003eTeacher punishment appropriateness and trust\u003c/h3\u003e\n\u003cp\u003eIn daily teaching, educators often face the challenging task of delivering negative messages or critical feedback to students, a necessity for effective education [\u003cspan citationid=\"CR13\" class=\"CitationRef\"\u003e13\u003c/span\u003e]. Additionally, teachers must enforce school regulations by punishing violators in a manner that reflects the severity of the infraction, all while maintaining effective classroom management. The severity of punishment should be proportionate to the wrongdoing [\u003cspan citationid=\"CR14\" class=\"CitationRef\"\u003e14\u003c/span\u003e], however, punitive interventions, which serve as external motivators, can have a dual effect: they may promote short-term compliance with norms, but they can also erode interpersonal trust and supplant individuals' internal motivation to adhere to norms, potentially leading to a swift resurgence of undesirable behavior once the punitive measures are removed [\u003cspan citationid=\"CR15\" class=\"CitationRef\"\u003e15\u003c/span\u003e]. Teachers who exhibit unprofessional behavior in the classroom [\u003cspan citationid=\"CR16\" class=\"CitationRef\"\u003e16\u003c/span\u003e] and display high levels of verbal aggression are often perceived as less credible by their students [\u003cspan citationid=\"CR17\" class=\"CitationRef\"\u003e17\u003c/span\u003e]. When students view their course grades, course procedures, or teacher communication as unfair, they are more likely to engage in indirect attacks on the teacher [\u003cspan citationid=\"CR18\" class=\"CitationRef\"\u003e18\u003c/span\u003e]. Consequently, it is hypothesized that appropriate punishment can foster trust, whereas inappropriate punishment can erode it (Hypothesis 1).\u003c/p\u003e \u003cdiv id=\"Sec3\" class=\"Section2\"\u003e \u003ch2\u003eThe mediating role of trustworthiness\u003c/h2\u003e \u003cp\u003eTrustworthiness is assessed based on the presence or absence of motivation to deceive. According to Mayer et al. [\u003cspan citationid=\"CR19\" class=\"CitationRef\"\u003e19\u003c/span\u003e], the comprehensive ABI model distinguishes the structural components of trustworthiness (ability, benevolence, and integrity) from the perceived factors that contribute to trust. The fairness heuristic theory suggests that fairness plays a significant role in the formation of trustworthiness [\u003cspan citationid=\"CR20\" class=\"CitationRef\"\u003e20\u003c/span\u003e], and the appropriateness of a punishment indirectly reflects whether the punisher possesses fair traits. Third-party punishment enables punishers to signal qualities such as trustworthiness, and imposing sanctions in response to violations can enhance the punisher's reputation, indicating that they are fair and trustworthy [\u003cspan citationid=\"CR21\" class=\"CitationRef\"\u003e21\u003c/span\u003e]. In comparison to non-punishers, third-party punishers are more trusted and exhibit more trustworthy behavior.\u003c/p\u003e \u003cp\u003eTrustworthiness is a strong predictor of an individual's trust in leaders, teachers, or managers [\u003cspan citationid=\"CR22\" class=\"CitationRef\"\u003e22\u003c/span\u003e]. Research in higher education has shown that competence, kindness, and integrity directly influence students' trust in professors, rather than serving as prerequisites for such trust [\u003cspan citationid=\"CR23\" class=\"CitationRef\"\u003e23\u003c/span\u003e]. In this process, individuals form trust in authority based on their perceptions of the authority's trustworthiness, which provides a clearer explanation for why one person might trust another. It is proposed that trustworthiness mediates the relationship between the appropriateness of teacher discipline and students' trust in teachers, suggesting that a teacher's trustworthiness plays a crucial role in fostering trust (Hypothesis 2).\u003c/p\u003e \u003c/div\u003e\n\u003ch3\u003eThe moderating effect of teacher care\u003c/h3\u003e\n\u003cp\u003eA positive correlation exists between teacher trustworthiness and students' behavioral tendencies, encompassing out-of-class interactions, participation in class discussions [\u003cspan citationid=\"CR24\" class=\"CitationRef\"\u003e24\u003c/span\u003e], teacher evaluations, and cognitive-emotional learning outcomes [\u003cspan citationid=\"CR25\" class=\"CitationRef\"\u003e25\u003c/span\u003e]. The constructs of teacher resilience, buoyancy, and care have been found to significantly influence student engagement [\u003cspan citationid=\"CR26\" class=\"CitationRef\"\u003e26\u003c/span\u003e]. However, the predictive potential of \"teacher care\" as a variable in fostering positive interpersonal relationships has been relatively underexamined [\u003cspan citationid=\"CR27\" class=\"CitationRef\"\u003e27\u003c/span\u003e]. To establish strong relationships, teachers must understand their learners, demonstrate care for their needs, and respect their perspectives. In addition to teaching and learning issues, teachers bring their own value systems, beliefs, mindsets, and behaviors into the classroom, which can indirectly influence learners. Teachers who prioritize students' well-being can instill trust, encouraging enthusiastic engagement in the classroom environment [\u003cspan citationid=\"CR28\" class=\"CitationRef\"\u003e28\u003c/span\u003e]. By establishing close connections with students, teachers can create a comfortable and supportive learning environment, facilitating safe communication within the classroom [\u003cspan citationid=\"CR29\" class=\"CitationRef\"\u003e29\u003c/span\u003e]. Caring teachers can foster a trustworthy learning atmosphere, making students more inclined to participate in learning activities. A warm and friendly teacher-learner relationship can significantly enhance learners' willingness to communicate [\u003cspan citationid=\"CR30\" class=\"CitationRef\"\u003e30\u003c/span\u003e], reduce dropout rates [\u003cspan citationid=\"CR31\" class=\"CitationRef\"\u003e31\u003c/span\u003e], and foster positive teacher-student rapport, encouraging active interaction with teachers and classmates [\u003cspan citationid=\"CR32\" class=\"CitationRef\"\u003e32\u003c/span\u003e]. Therefore, we propose that teacher care plays a moderating role in the relationship between the appropriateness of discipline and teacher trustworthiness (Hypothesis 3).\u003c/p\u003e \u003cp\u003eThis study, grounded in prior research, investigates the relationship between teacher punishment appropriateness and student trust among adolescents, employing a moderated mediation model to elucidate the underlying mechanisms.\u003c/p\u003e"},{"header":"Method","content":"\u003cdiv id=\"Sec6\" class=\"Section2\"\u003e \u003ch2\u003eStudy 1\u003c/h2\u003e \u003cdiv id=\"Sec7\" class=\"Section3\"\u003e \u003ch2\u003eParticipant\u003c/h2\u003e \u003cp\u003eA junior high school in Henan Province, China, was selected for this study, and 243 questionnaires were distributed using cluster sampling, yielding 224 valid responses (92.2% response rate).

Model 7 in the PROCESS program, we tested the moderating effect of teacher care on the relationship between discipline appropriateness and trustworthiness, controlling for students' gender, age, and

The results (Table\u0026nbsp;\u003cspan refid=\"Tab2\" class=\"InternalRef\"\u003e2\u003c/span\u003e) show that teacher care significantly predicts trustworthiness (\u003cem\u003eβ\u003c/em\u003e = 0.26, \u003cem\u003ep\u003c/em\u003e \u0026lt; 0.001).

However, several limitations warrant further investigation. The reliance on self-reported data from subjects introduces potential subjective bias and social desirability bias, which may compromise the objectivity and generalizability of the findings. Furthermore, the non-significant moderating effect of teacher care on the relationships between variables suggests that this factor may not play a crucial role in this context. This outcome may be attributed to various factors, including sample characteristics, measurement tools, and cultural background. To address this, follow-up studies should investigate the regulatory role of teacher care in greater depth. Additionally, the study's sample is limited to urban middle school students, whereas the education of rural left-behind children has significant implications for human capital accumulation and economic growth. Therefore, it is essential to replicate and extend the research to rural middle school students to enhance the generalizability and applicability of the findings.\u003c/p\u003e \u003c/div\u003e \u003cdiv id=\"Sec19\" class=\"Section2\"\u003e \u003ch2\u003eStudy 2\u003c/h2\u003e \u003cdiv id=\"Sec20\" class=\"Section3\"\u003e \u003ch2\u003eParticipant\u003c/h2\u003e \u003cp\u003eTo reach 80% (1-β) statistical power, the study required at least 159 subjects, as assessed by G*Power 3.1.The experiment chose a township middle school in Henan Province, China, and utilized a cluster sampling approach to disseminate 260 surveys, yielding 239 valid questionnaires and a recovery rate of 91.92%.

After adjusting for age, gender, and academic performance, the study found that appropriate punishment has a substantial direct influence on trustworthiness (\u003cem\u003eβ\u003c/em\u003e = 0.37, \u003cem\u003ep\u003c/em\u003e \u0026lt; 0.001) and trust (\u003cem\u003eβ\u003c/em\u003e = 0.17, \u003cem\u003ep\u003c/em\u003e \u0026lt; 0.01).Then, using the direct effects, trustworthiness was introduced as a mediating variable while controlling for age, gender, and grades. The direct effects of appropriate punishment on trustworthiness and trust continue to be important; appropriate punishment can strongly predict trustworthiness. Trustworthiness also greatly predicts trust. The bootstrap test findings suggest that the mediating effect of trustworthiness is 0.14, 95%CI = [0.08, 0.20].

The results of Study 2 confirmed the moderating role of teacher care between the appropriateness and trustworthiness of punishment, indicating that teacher care indeed influences students' perception and acceptance of punishment. This finding holds significant implications for educational practice, emphasizing that teachers need to consider students' feelings and needs when maintaining classroom order and implementing punitive measures, thereby enhancing the effectiveness of punishment through the demonstration of teacher care. Moreover, Study 2 specifically focused on a sample of rural middle school students for further exploration. This approach helps to address the shortcomings in sample representativeness of previous studies, as rural students may face different educational environments and challenges compared to urban students.\u003c/p\u003e"},{"header":"Discussion","content":"\u003cp\u003eThis study investigated the relationship between the appropriateness of teacher punishment for adolescents and their trust in teachers, as well as the potential mechanisms underlying this relationship.

This is consistent with previous research, which indicates that punishment not only has a direct impact on the responsible party and those affected but also has a ripple effect on observers. The effectiveness of punitive interventions depends on their legitimacy. When punishment is misused, it not only fails to effectively maintain norms but also undermines the positive effects of legitimate punishment, leading to a decline in the level of group cooperation [\u003cspan citationid=\"CR40\" class=\"CitationRef\"\u003e40\u003c/span\u003e, \u003cspan citationid=\"CR41\" class=\"CitationRef\"\u003e41\u003c/span\u003e].\u003c/p\u003e \u003cdiv id=\"Sec33\" class=\"Section3\"\u003e \u003ch2\u003eThe mediating role of trustworthiness\u003c/h2\u003e \u003cp\u003eThe present study found that trustworthiness plays a mediating role in the relationship between the appropriateness of teacher punishment and students' trust in teachers. The more appropriate the teacher's punishment, the more likely junior high school students are to perceive the teacher as trustworthy, thereby eliciting a higher level of trust. Conversely, compared to appropriate punishment, inappropriate punishment has a detrimental impact on junior high school students' perception of trustworthiness, ultimately leading to a decrease in trust. Therefore, teachers' appropriate use of punishment can enhance their trustworthiness and foster trust, while inappropriate punishment can diminish their trustworthiness and undermine students' trust in them.\u003c/p\u003e \u003c/div\u003e \u003cdiv id=\"Sec34\" class=\"Section3\"\u003e \u003ch2\u003eThe Moderating Role of Teacher Care\u003c/h2\u003e \u003cp\u003eThis study elucidates the moderating effect of teacher care in constructing the relationship between teacher trustworthiness and the appropriateness of teacher punishment. When punitive measures are inappropriate, caring behaviors by teachers can effectively mitigate the negative impacts arising from such misjudged punishment, thereby safeguarding the teachers' trustworthy image in the eyes of students. The presence of emotional support from teachers can assist students in establishing positive teacher-student relationships, enhancing students' sense of security and belonging, and consequently boosting their trust in teachers. However, as the appropriateness of teacher punishment increases, the mitigating effect of teacher care on students' sense of trust gradually diminishes. This suggests that when teachers' punitive actions are just, reasonable, and in line with students' expectations, students' trust in teachers relies on the teachers' integrity rather than excessively on their care. Therefore, when implementing punishment, a just and upright image of teachers is more capable of enhancing students' evaluation of their trustworthiness.\u003c/p\u003e \u003cp\u003eIt is noteworthy that a higher level of teacher care is not always better. There exists a threshold for the level of teacher care; once this threshold is exceeded, the growth in perceived trustworthiness of teachers will become sluggish. In contrast, for urban children, high care has a positive effect on rural children, with teachers who are punitive but caring receiving higher ratings than those who are appropriately punitive but less caring. For rural children, who often live apart from their parents and are primarily cared for by grandparents or other elderly relatives, intergenerational care constitutes the predominant parenting model in left-behind children's families. The grandparents or other elderly caregivers of these rural left-behind children generally have lower levels of education, with many being illiterate, leading to a relative lack of parental love and education. This results in most left-behind children developing sensitive, introverted, and even inferior personality traits, lacking familial affection in their emotional and psychological well-being. Meanwhile, the implementation of effective emotional care strategies by homeroom teachers can yield immediate and highly efficient outcomes. Thus, it is evident that the level of teacher care and the manner of punishment have complex impacts on their perceived trustworthiness. Teachers need to strike a balance between an appropriate level of care and proper punitive methods to foster students' trust and respect towards them.\u003c/p\u003e \u003c/div\u003e \u003c/div\u003e\n\u003ch3\u003eEducational advice\u003c/h3\u003e\n\u003cp\u003ePunishment, as a means of behavioral correction and discipline maintenance, plays a vital role in the educational process. However, the implementation of punishment must be founded on the principle of justice to ensure the protection of students' rights and dignity. To achieve a well-ordered and benevolent governance in educational justice, a just and virtuous \"good system\" is inevitably required. Educational punishment is an educational method and an expression of teachers' care for students' development and growth. Yet, whether teachers truly care for students depends not only on the teachers' willingness and actions to care but also on students' perception of these caring behaviors.\u003c/p\u003e \u003cp\u003eIn the realm of educational practice, educational justice should be embodied in an educational system with the spirit of good values as its soul, serving as an effective tool for educational governance. Schools should establish and publicize clear behavioral norms and standards of punishment, ensuring that students understand which behaviors are permitted and which are prohibited. The implementation of punishment should follow a reasonable procedure, including informing students in advance of the impropriety of their actions, listening to their defenses, and making fair decisions based on evidence and circumstances. During the punishment process, students' rights and dignity should be fully respected, and the use of corporal punishment, humiliation, or other inhumane punitive measures should be avoided. For students who exhibit inappropriate behavior, teachers should provide appropriate guidance and support to help them recognize their mistakes, correct their behavior, and get back on track. Schools should regularly evaluate the effectiveness of punishment, checking whether it has achieved the intended goals and adjusting as necessary. Teachers and administrators should maintain open communication with students, parents, and other educators, collecting their feedback and suggestions on punishment and educational care. Based on the evaluation results and feedback, schools should continuously improve their punitive mechanisms and educational care strategies to ensure that they are just, effective, and supportive.\u003c/p\u003e\n\n"},{"header":"Conclusions and Limitations","content":"\n\u003ch3\u003eConclusion\u003c/h3\u003e\n\u003cp\u003eThis paper explores the role of teacher care between the appropriateness of teacher punishment and teacher credibility, as well as the mediating effect of credibility, through two studies.
