As a long-established model of schooling, the boarding system is commonly practiced in countries around the world. Numerous scholars have conducted a great deal of research on the relationship between the boarding school and student development, but the results of the research are quite divergent. In order to clarify the real effects of boarding school on students’ development, this study used meta-analysis to quantify 49 (91 effect sizes) experimental or quasi-experimental studies on related topics at home and abroad. The results find that: (1) Overall, boarding school has no significant predictive effect on student development, with a combined effect size of 0.002 (p > 0.05); (2) Specifically, boarding school has a significant positive predictive effect on students’ cognitive development (g = 0.248, p < 0.001), a significant negative predictive effect on students’ affective and attitudinal development (g = −0.159, p < 0.05), and no significant predictive effect on students’ behavioral development (g = −0.115, p > 0.05) and physical development (g = −0.038, p > 0.05); (3) The relationship between the two is moderated by the school stage and the type of boarding school, but not by the instruments; (4) Compared with primary school students, senior high school students and urban boarding students, the negative predictive effect of boarding system on junior middle school students and rural boarding students is more significant. In addition, there are some limitations in the study, such as the limited number of moderator variables included, the results of the study are easily affected by the quality of the included literature, and the dimensionality of the core variable “student development” is not comprehensive enough. In the future, further validation should be conducted through in-depth longitudinal or experimental studies.

Introduction: The popularization and widespread use of smartphones and other electronic devices have led to the occurrence of “parents phubbing”, which may have a negative impact on child-parent relationship and preschoolers’ prosocial behavior.Methods: To clarify this process, a questionnaire survey was conducted with 3,834 parents from 20 kindergartens in Zhuhai, China. This study examined the relationship between between parents phubbing, closeness child-parent relationship, authoritative parenting style and children’s prosocial behavior.Results: According to the study, we found a significant negative correlation between parents phubbing and preschoolers’ prosocial behavior. Closeness child-parent relationship mediated between parents phubbing and preschoolers’ prosocial behavior through mediation effects analysis. In other words, parent phubbing was negatively associated with closeness child-parent relationship, which in turn predicted less child prosocial behavior. In addition, authoritative parenting styles have a moderating effect. As the level of authoritative parenting style increases, the negative impact of parent phubbing on the prosocial behavior of preschool children is attenuated.Discussion: This study contributes to the understanding of the relationship between parents phubbing and prosocial behaviors of preschool children, as well as the internal mechanisms at work. Practically, the study suggests that parents should reduce the incidence of phubbing in their contact with their children and, at the same time, work to improve the child-parent relationship and promote the development of prosocial behaviors in children.

Introduction: With the rapid development of information technology, emerging electronic media are widely used in various settings where children are present. At the same time, excessive screen exposure has been associated with various emotional symptoms in preschool children.Methods: This study employed a questionnaire survey to collect data from 7,239 parents of preschool children in Pu’er City, China. After rigorous data screening, 6,623 valid responses were retained for analysis. The collected data were then analyzed using SPSS 25.0 for descriptive and inferential statistics, and Hayes’ PROCESS 4.0 was used to test the mediation and moderation models involving digital screen exposure, the parent-child relationship, peer relationships, and emotional symptoms in preschool children.Results: The results indicated that digital screen exposure was significantly associated with emotional symptoms (β = 0.2351, p < 0.01). Specifically, higher levels of screen exposure were associated with more severe emotional symptoms, and this association was mediated by the parent-child relationship (indirect effect = 0.06, 95% CI [0.03, 0.08]). Peer relationships moderated the association between digital screen exposure and emotional symptoms (interaction effect = −0.22, p < 0.01) and between digital screen exposure and the parent-child relationship (interaction effect = −0.12, p < 0.01).Discussion: This study provides a comprehensive theoretical framework to understand the associations among digital screen exposure, emotional symptoms, and social relationships in preschool children. It highlights the potential importance of the parent-child relationship and peer relationships in buffering negative associations related to digiatl screen exposure.

Numerous studies have been conducted on the correlation between preschool children’s executive functions and mathematical competence, the findings of those studies are inconsistent. This study used meta-analysis to investigate the correlation between executive functions and mathematical competence of preschool children in China, and then explored the moderating effects of age, gender, and instruments. The researchers conducted an extensive search of CNKI, Web of Science, Google Scholar and used screening criteria to identify 22 studies of Chinese preschoolers aged 3–7 years from 2007 to 2021. The findings indicated that there was a positive correlation between Chinese preschool children’s executive functions and mathematical competence (r = 0496), of which the effect size between mathematical competence and inhibition control was 0.347, and the effect size for working memory was 0.432, with an effect size of 0.370 for cognitive flexibility. Furthermore, Moderation analysis suggests that the preschoolers’ age, gender, and instruments affected the association between the executive functions and mathematical competence. The implications of these findings for theory and practice deserve further discussion.

Kindergarten climate has been reported to be closely associated with teachers' retention intention, yet the underlying mechanism of this association remains unclear in some ethnic minority areas in China. Based on the Personal-Environment Fit Theory and Organizational Support Theory, the research aims to examine the correlation between kindergarten climate and retention intention of Chinese kindergarten teachers in ethnic minority areas and the chain mediating role of perceived organizational support, as well as the psychological empowerment. In total, 1,199 Chinese kindergarten teachers were recruited from ethnic minority areas to complete the questionnaires. Based on their responses, the main findings of the study were listed as follows: (1) A supportive kindergarten climate has a positive correlation with perceived organizational support, psychological empowerment, and retention intention. (2) A positive kindergarten climate would increase the retention intention only through the indirect path of perceived organizational support, psychological empowerment, as well as the chain mediating path between these two variables. Taken together, these results further explained the interplay between kindergarten climate and teachers' retention intention. Implications for research on retention intention were discussed. Theoretically, it enriches the theoretical basis related to the external environmental resources and individual cognition. Practically, it means that educational policymakers will need to issue new guidelines to ensure that more kindergarten teachers are retained in China's ethnic minority areas.
