Long COVID, where symptoms persist after recovering from COVID-19, can affect cognitive functions like language. However, little is known about its impact on children’s language skills, especially across different school levels. This study investigated the impact of long COVID on language proficiency among 1244 children (Asian; 53.5% boys) from kindergartens (N = 408, Mage = 4.42 ± 1.26 years), primary schools (N = 547, Mage = 9.69 ± 1.96 years), and secondary schools (N = 289, Mage = 14.97 ± 1.85 years) in Hong Kong. Language proficiency was assessed using the Language Experience and Proficiency Questionnaire (LEAP-Q), which measured speaking, listening, reading, and writing in both Chinese and English. Participants were categorized into three groups: long COVID, recovered from COVID-19, and no history of COVID-19. One-way and two-way ANOVAs were used to analyze the differences in language proficiency across these groups and school levels. Children with long COVID symptoms exhibited significantly lower overall language proficiency, particularly in speaking and listening, compared to those in the recovered and no-COVID groups. The effect was more pronounced among primary and secondary students, with secondary school students showing the most substantial deficits. No significant differences were found between the recovered and no-COVID groups. The results suggest that long COVID might have detrimental effects on children’s linguistic proficiency. The language development of older students who suffered from long COVID could benefit from receiving targeted educational and therapeutic interventions. Copyright © 2025 by the authors.

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.

This study examines the impact of a seamless learning environment combined with a multicultural educational environment on the cognitive development of preschool children in Hong Kong (n = 200). Using a quasi-experimental design, this study compared the cognitive development of children in an experimental group exposed to continuous learning and multicultural elements with those in a control group using traditional teaching methods. The main methodology included the use of ANOVA (analysis of variance) to study the differences in cognitive development between these groups at three stages of testing. Initially, both groups showed similar results, with averages of about 49 points, providing a comparable starting point. However, over time, the experimental group exposed to seamless learning and a multicultural environment showed significant growth. Six months later, the average score in this group increased to 61.52 and reached 74.42 after one year, indicating a significant improvement in cognitive abilities. The intermediate and subsequent testing results showed remarkable cognitive improvements in the experimental group compared to the control group, indicating the effectiveness of a seamless multicultural learning environment in enhancing cognitive development. This research contributes to educational psychology by providing empirical evidence on the benefits of innovative and culturally diverse learning environments in preschool education. Copyright © 2025 Informa UK Limited, trading as Taylor & Francis Group.

Students' perceived competencies may reflect dispositions to trigger and enhance engagement acts and promote engagement benefits. Although perceived competencies and engagement acts are significant resources in STEM learning, their relationships remain unclear. Accordingly, we applied the transactional model of engagement (TME) to examine these associations, focusing on how emotional and cognitive engagement affect the mediating effect of perceived digital inquiry on perceived creativity. The participants were 305 secondary school STEM learners in Hong Kong. Mediation analyses showed that emotional engagement mediated the positive relationship between perceived digital inquiry and creativity, whereas cognitive engagement had no such mediating effect.

High-quality caregiver-child relationships are critical to healthy development, including the acquisition of language and literacy skills. However, their potential benefits to early mathematical development and its underlying mechanisms have been minimally explored. In view that language and literacy development play prominent roles in mathematical development, this study investigated whether very young children's relationship quality with parents and teachers were linked with their mathematical ability through language and literacy abilities. One hundred and thirty two-year-olds from pre-nursery classes in Hong Kong were tested on their early academic abilities. Furthermore, their parents and teachers evaluated on questionnaires the quality of their relationships with the children. Results of path analyses indicated that after controlling for children's age, parent-child closeness was associated with children's mathematical ability via language ability. Teacher-child closeness had a direct link to children's mathematical ability, as well as indirect links through language and literacy abilities. Parent-child conflict and teacher-child conflict had neither direct nor indirect relations with children's mathematical ability. These results suggest that mathematical development is interwoven with language and literacy development beginning in the early years. Also, parents and teachers should be reminded the importance of building close and affectionate relationships with very young children when nurturing the foundation for academic development.

Computational thinking (CT) practices is a critical cognitive tool for students to overcome challenges in this technological era. Few studies investigated CT practices from a development perspective. A two-year intervention was implemented in 30 intervention and 22 control schools in Hong Kong to promote CT education (T1baseline: N = 13,056; T2: N = 16,367; and T3: N = 15,269). Senior primary students (grades 4 to 6) around 8–12 years old were targeted. Among them, 34% were girls at T1baseline. Their learning progression of cognitive development was assessed with a CT practices test. Data were analyzed using item response analysis. Learning trajectories of CT practices were modeled to understand how students’ cognitive development differed between schools. Insights of findings were discussed in bringing CT practices to life. Copyright © 2023 Elsevier Ltd. All rights reserved.

The purpose of this study is to investigate into the possibility of utilizing socio-scientific issues as a vehicle to promote students’ metacognitive regulation, self-efficacy and conceptual understanding in an ecology classroom in Hong Kong. There has been little research to assess how these constructs are influenced by an issue-based inquiry classroom environment set in ecological context, and how these constructs interact with each other. The researcher has designed a metacognitive-rich environment for learning through a socio-scientific issue in a high school ecology classroom. Students’ perceptions about the metacognitive orientation of the classroom environment were assessed by the Metacognitive Orientation Learning Environment Scale (Science) to provide evidence for the validity of the lesson design in creating a metacognitive-rich environment. The effect of embedding explicit metacognitive tasks into a socio-scientific issue on students’ self-efficacy and metacognition were assessed through a quasi-experimental study using the Motivation Strategy for Learning Questionnaire and post-lesson individual interviews. 54 students from a Hong Kong long-established boy school participated in this study. The changes of the dependent variables under study were analyzed using an independent samples t-test and a 2x2 mixed-design analysis of variance to indicate the effect of this specially designed intervention in the biology classroom. The quantitative results suggested the intervention has created significant positive effects on students’ metacognitive regulation and self-efficacy but not conceptual understanding. Results from the multivariate analysis of variance and Pearson correlations suggest that the three dependent variables under study are correlated. To assist in the interpretation of the quantitative findings, individual interviews with students in the intervention group were analyzed thoroughly based on the concurrent triangulation approach. The interview results

In Content and Language Integrated Learning (CLIL) programmes, students learn content knowledge and a second/foreign language (L2) simultaneously. It follows that both content and language are assessed, although research on how to do so remains scarce. This study explores the interplay between cognitive and linguistic demands of CLIL assessments. Having analysed over 4900 questions in Science/Biology textbooks, workbooks and examination papers in Hong Kong, we observed that junior secondary assessments were dominated by low-level cognitive (i.e. recall of knowledge) and linguistic (i.e. no production or word-level production) demands, whereas senior secondary assessments required higher-order thinking skills (i.e. application and analysis of knowledge) expressed in sentences or even texts. Also, based on the analysis of 70 junior secondary students' performance in school examination papers, we noticed a potential hindrance of linguistic demands to students' performance in CLIL assessments. These findings together underscore the integral role of language in CLIL assessments and raise questions about the adequacy of existing pedagogical practices in preparing students to tackle both cognitive and linguistic demands in CLIL assessments, particularly when they proceed to higher grade levels where the demands in both dimensions leap. These have significant implications for CLIL assessment design, pedagogy and teacher education. Copyright ©Routledge.
