Objective: Physical activity (PA) is critical for healthy development in preschoolers, with long-lasting benefits that can affect later life. The World Health Organization (WHO) recommends that children aged 5–17 years should engage in 60 min of moderate-to-vigorous PA per day. However, physical inactivity in children is on the rise globally, with declines in PA starting at the age of 4 years. Increasing PA during early childhood is important to delay adiposity rebound, promote behavioral changes, improve physical fitness, and facilitate future PA engagement. However, limited evidence has been established on the effects of school-based PA interventions on preschoolers. This study examines the effects and sustainability of a preschool-based PA intervention on increasing PA, improving physical fitness and health in preschoolers, with the exercise dose benchmarked to the WHO PA guidelines. Methods: This assessor-blinded, two-arm cluster randomized controlled trial will include 3300 preschoolers (aged 5–6 years) from 110 kindergartens in Hong Kong, China. Kindergartens will be randomized into intervention and control groups in a 1:1 ratio. The control kindergartens will continue their usual curriculum of ∼2.5 h PA/week, whereas preschoolers in the intervention kindergartens will engage in an additional 75-min game-based PA class twice per week (extra 2.5 h PA/week) over the preschool year. This multi-component intervention will also target parents, teachers, and the kindergarten environment to further encourage PA in preschoolers and their families. Objectively measured PA, cardiorespiratory fitness and other physical fitness components (muscle strength and power, agility, balance, flexibility, body composition), and psychological health will be examined at the start (0 month) and end (10 months) of the preschool year. Maintenance effects will be assessed after preschoolers’ transition into primary school (16 months). Generalized estimating equations or other appropriate

Prior research on COVID-related school disruptions focused mainly on primary or secondary, with limited studies on kindergarten children. Using a naturalistic quasi-experimental design, we examined whether school disruption during the first year of kindergarten (K1) affected early numeracy, literacy, and non-academic development. We also examined whether disruption during the first or second year of kindergarten (K2) was more detrimental to children's development. A cohort of K2 students from each of two consecutive years (N = 235, 4–5-year-old) were recruited from ten kindergartens in Hong Kong, which had long periods of COVID-related school disruptions. One cohort was assessed just before the onset of COVID-19; the other, one year later. K1 disruption did not affect performance at K2. In contrast, performance at K3 showed that K2 disruption had a more detrimental effect on physical performance than K1 disruption. Findings highlight the period and aspects of children's development that are particularly sensitive to schooling. Copyright © 2025 Informa UK Limited, trading as Taylor & Francis Group.

Research Findings: Early childhood educators' own disposition has been suggested to contribute to their ability to promote physical literacy (PL) in young children. There is currently limited evidence of educators' own PL, and studies have not explored how PL relates to teaching knowledge and behaviors in the early childhood education (ECE) context. This current study examined the relationships of teachers' perceived PL with their self-efficacy and perceived professional competence in relation to promoting physical activities in ECE settings. A total of 338 early childhood educators from Hong Kong responded to an online survey that consisted of the Perceived Physical Literacy Inventory (PPLI), Chinese version of the Teacher Sense of Efficacy Scale (C-TSE(R)), and Teachers' Professional Competence (TPC) questionnaire. The findings revealed that educators' perceived PL is moderately associated with self-efficacy and professional competence when conducting physical activities in ECE contexts. The PL attributes of self-expression and communication, and knowledge and understanding were significant predictors of educators' self-efficacy in classroom management and teaching strategies, as well as their professional knowledge and attitudes. Practice or Policy: The findings suggest that ECE teachers' training should consider aspects of their own PL to enable their self-efficacy and perceived competence for conducting physical activities in ECE settings and thereby promote the PL of young children.

The rapid development of social media tools has increased interest in their pedagogical value. It has been suggested that social media tools such as wikis can promote online collaborative and interactive learning. This study investigated the value of wikis in supporting collaborative group writing quality among secondary school students in Hong Kong. Students from a local secondary school engaged in group writing projects using Pbworks, a popular wiki tool. Data were gathered from (1) the revision tracking history, (2) a questionnaire on the perceived pedagogical value of the wiki, and (3) group interviews with students. Findings showed that students who made more collaborative revisions on the wiki produced higher-quality writing output. In general, students reported a moderately positive attitude towards the pedagogical value of the wiki. The findings suggest that wikis promote collaborative writing, but teachers need to adopt pedagogical strategies that would equip students to use wikis.
