Significant findings include that physical exercise could substantially enhance the adolescents’ social and emotional skills across all domains, with comparatively stronger effects on emotion regulation and engaging with others; that strengthening physical exercise is of particularly vital significant for socioeconomically disadvantaged adolescents; and that the positive effects of physical exercise on social and emotional skills increased with age in the teenagers; and that gender was an insignificant factor in the relationships between physical exercise and social and emotional skills.</p> Jun Yan Tianci Lu Copyright (c) 2026 Best Evidence in Chinese Education https://creativecommons.org/licenses/by-nc/4.0 2026-01-27 2026-01-27 22 1 2055 2059 10.15354/bece.26.ar005 https://mail.bonoi.org/index.php/bece/article/view/1696 <p>Amid intensifying social competition, household human capital investment has gradually become a heavy burden for the families, which instigates widespread educational anxiety. Educational involution not only hinders the overall improvement of educational quality but is also detrimental to students' physical and mental health. The household educational burden is a pronounced issue in the implementation of the Double Reduction policy. Based on data from the China Family Panel Studies 2010-2020, this study empirically investigates the impact of the household educational burden on family well-being using an Overlapping Generations model.</p> Qian Wang Copyright (c) 2026 Best Evidence in Chinese Education https://creativecommons.org/licenses/by-nc/4.0 2026-01-27 2026-01-27 22 1 2061 2062 https://mail.bonoi.org/index.php/bece/article/view/1697 <p>Class size reduction is a popular move to improve student academic achievement in many countries and territories. Based on the PISA 2022 data, this study compares the distribution characteristics of class sizes between East Asian countries/territories and OECD countries using chi-square tests, examines the relationship between class size and student mathematics achievement in East Asia through OLS regression models, and analyzes the heterogeneous effects of class size among students with varying levels of math performance using quantile regression models.</p> Shifei Duan Copyright (c) 2026 Best Evidence in Chinese Education https://creativecommons.org/licenses/by-nc/4.0 2026-01-27 2026-01-27 22 1 2063 2063 https://mail.bonoi.org/index.php/bece/article/view/1698 <p>The emerging generative artificial intelligence (GenAI) technology has the potential to become strong technological support for further reform and innovation in education by enriching instructional devices and modalities. Nevertheless, its specific effects on student outcomes remains contentious in academia. This article, using meta-analytical techniques, systematically reviews 39 experimental and quasi-experimental studies (encompassing 60 effect sizes) published before June 2024, aiming to investigate the effect of GenAI use on student outcomes and its moderating factors.</p> Li Qian Copyright (c) 2026 Best Evidence in Chinese Education https://creativecommons.org/licenses/by-nc/4.0 2026-01-27 2026-01-27 22 1 2065 2066 https://mail.bonoi.org/index.php/bece/article/view/1699 <p>Perceived organizational support plays a central role in career adaptation and professional development of primary and secondary teachers. Factors influencing the relationship between perceived organizational support and turnover intention in this group have been under-researched. This study is an investigation of the said relationship and the effects of teacher career adaptability and social capital on the relationship based on a questionnaire survey of 1118 Chinese primary and secondary teachers through online questionnaire platforms.</p> Yao Xiao Copyright (c) 2026 Best Evidence in Chinese Education https://creativecommons.org/licenses/by-nc/4.0 2026-01-27 2026-01-27 22 1 2067 2067 https://mail.bonoi.org/index.php/bece/article/view/1700 <p>Most surveys on school-based bullying focus on the perspective of the victims. Empirical research on bullying perpetration among primary and secondary school students is relatively scarce. In effect, the prevention of bullying in schools involves various parties, including perpetrators, victims, and bystanders. It is particularly important to monitor bullying perpetrators to control their offensive behaviors and prevent potential harm to others. Based on large-scale education monitoring data from a province in eastern China, this study aims to analyze the effects of individual competence and interpersonal relationships on bullying perpetration in primary and secondary school students in China using methods of logistic regression, Owen decomposition, and random forests.</p> Jiazhe Li Copyright (c) 2026 Best Evidence in Chinese Education https://creativecommons.org/licenses/by-nc/4.0 2026-01-27 2026-01-27 22 1 2069 2070
