Impact of a mindfulness-based intervention on well-being and mental health of elementary school children: results from a randomized cluster trial.

Prevention programs, such as mindfulness-based interventions (MBIs), are often implemented in schools to prevent psychological disorders from emerging in children and to support their mental health. This study used a randomized cluster design to evaluate the impact of a MBI, called Mission Méditation, on the well-being and the mental health of elementary school children's. 13 classrooms of an elementary school were randomly allocated to the experimental condition (7 classrooms, n = 127 students) or the waitlist control condition (6 classrooms, n = 104 students). Participants in the experimental condition received a 10-week MBI. Regression analyses revealed significant differences between conditions for inattention. Participants in the MBI condition reported no change in pre- to post-intervention, whereas participants in the control condition reported pre- to post-intervention increases. Results also showed significant differences in perceived competence. Participants in the MBI condition reported a non-significant decrease in perceive competence, whereas participants in the control condition reported significantly higher perceive competence scores from pre- to post-intervention. Results do not indicate that the MBI had a significant impact on participant's well-being and mental health. This suggests that MBIs may not have an added value when compared to other preventive interventions geared towards well-being and mental health promotion in school settings.

Development of self-derivation through memory integration and relations with world knowledge.

Accumulating world knowledge is a major task of development and education. The productive process of self-derivation through memory integration seemingly is a valid model of the process. To test the model, we examined relations between generation and retention of new factual knowledge via self-derivation through integration and world knowledge as measured by standardised assessments. We also tested whether the productive process of self-derivation predicted world knowledge even when a measure of learning through direct instruction also was considered. Participants were 162 children ages 8-12 years (53% female; 15% Black, 6% Asian, 1% Arab, 66% White, 5% mixed race, 7% unreported; 1% Latinx). Age accounted for a maximum of 4% of variance in self-derivation and retention. In contrast, substantial individual variability related to general knowledge and content knowledge in several domains, explaining 20-40% variance. In each domain for which self-derivation performance was a unique predictor, it explained a nominally greater share of the variance than the measure of learning through direct instruction. The findings imply that individual variability in self-derivation has functional consequences for accumulation of semantic knowledge across the elementary-school years.

Examining the effectiveness of a social-play-based programme to reduce symptoms of Attention-Deficit/Hyperactivity Disorder in Saudi elementary school children.

BACKGROUND: Attention-Deficit/Hyperactivity Disorder (ADHD) is one of the most common neurodevelopmental conditions in children, and can profoundly affect their social interactions, well-being, and relationships with parents, peers, and teachers. OBJECTIVE: This study investigated the effectiveness of a social-play-based intervention programme in reducing ADHD symptoms in a sample of 67 Saudi boys aged 8-10 diagnosed with ADHD. METHODS: The programme consisted of ten 60-minute sessions of play-based activities, delivered to the experimental group twice weekly for 5 weeks. The control group followed the usual school curriculum. Teachers and parents completed the Conners' Teacher Rating Scale-Revised: Short Form and Conners' Parent Rating Scale-Revised: Short Form for all participants at pre-test, post-test, and follow-up. RESULTS: The experimental group showed a significant reduction in ADHD-associated behavioural problems over time, with moderate to large effect sizes. No significant changes over time were found for the control group. The results were maintained at a 2-month follow-up. CONCLUSIONS: We recommend incorporating social-play-based activities and skill training into the school context. Reducing ADHD symptoms may improve children's academic performance and perspective on school.

Unlocking narratives: Longitudinal associations between theory of mind and reading comprehension.

This study explores the longitudinal association between Theory of Mind (ToM) and reading comprehension (RC) in middle childhood, focusing on three advanced ToM (AToM) components: social reasoning, reasoning about ambiguity and recognition of social norm transgressions. Over the course of a year, 112 nine-year-olds (61 girls, 51 boys; Mage = 9; 0 years, ±4 months at wave 1) were followed from Grade 3 to Grade 4 and assessed for AToM predictors of Grade-4 RC. Findings show that only social reasoning predicts RC, independent of general intelligence and prior RC performance. In turn, RC did not predict any AToM component. These findings contribute to understanding cognitive development in educational contexts, emphasizing the significance of AToM, particularly social reasoning, in RC.

Decisions and Influential Factors Regarding Class-Specific School Closures Against Seasonal Influenza Outbreak.

Background One of the characteristics of school closure in Japan is class-specific school closure, which involves a reactive, short-term closure in the event of an infectious disease outbreak. These closures are implemented at each school in reaction to the annual seasonal influenza outbreaks. Very little research has addressed the formation of class-specific school closures to combat infectious diseases in elementary schools. We carried out a survey on factors involved in the decision to close classes and the determination of the timing and duration of class closures in elementary schools in Japan. Methods A mail-based questionnaire survey of elementary schools from four prefectures in western Japan was conducted between August and September 2021. The questions addressed the criteria for school closures (the timing and duration of class closure), various considerations, and confusion regarding class closures, with answers analyzed using descriptive statistical methods. Results In total, 714 elementary schools responded to the survey (37.9%). Furthermore, 398 (55.7%) schools established criteria for class closures during seasonal influenza. Class closure was most frequently initiated in schools with criteria when either 20% or 30% of class pupils were absent; the most common duration was three days. The duration of class closures was decided upon depending on the outbreak in some schools (69.8%), depending on the circumstances of the outbreak. Regarding class closure decisions, schools viewed school physicians' opinions as a priority, followed by school events, adjustments for Saturdays and Sundays, and Yogo teachers' opinions. Schools answering "no criteria for class closure" or "adjustments for Saturdays and Sundays" had difficulty determining class closure duration. Conclusion To guarantee the continuation of children's education and improve the effectiveness of preventive efforts against seasonal influenza, the following were considered important and helpful in class closure decision-making in elementary schools: scientific evidence, the school physician's opinion, and Yogo teachers' analysis of children's health information.

The factorial structure of executive functions in preschool and elementary school children and relations with intelligence.

The timing of structural changes in executive functions (EFs) across development is a matter of controversy; whereas some studies suggest a uniform structure of EFs in early childhood, findings in middle and late childhood are mixed. There are results indicating uniformity of EFs as well as several studies suggesting multidimensionality of the construct. In addition, studies demonstrate an age-related differentiation of the relation between EFs and intelligence. We conducted a comparative analysis of the EF structure and relations with fluid intelligence in two distinct age groups. A sample of n = 145 preschool children (5.2-6.7 years of age) and n = 109 elementary school children (8.8-11.8 years) completed measures of working memory, inhibition, cognitive flexibility, and fluid intelligence. Confirmatory factor analysis (CFA) revealed that a single-factor model best represented performance on EF tasks in both preschool and elementary school children. Multi-group CFA indicated equivalent and strong relations between EFs and intelligence across both age groups (r = .64 in preschool and elementary school children). Our results confirm that EFs are significantly related to fluid intelligence but might not underlie a uniform pattern of successive differentiation into multiple EF components in childhood. We discuss how methodological artifacts such as simultaneous interference might have contributed to previous findings on differentiation in middle and late childhood.

Perspectives of primary school teachers on the capacity of schools to support post-pandemic health needs emerging among school-age children.

BACKGROUND: This study aimed to explore the impact of the COVID-19 pandemic on capacity building for health promotion in primary schools from the perspectives of primary school teachers. METHODS: A cross-sectional observational study was conducted via an anonymous online survey between February and May 2022. Three-quarters (n2460) of all schools in the Republic of Ireland were invited to participate. Demographics such as gender, teaching experience, school type and delivering equality of opportunity in schools (DEIS) designation were collected. Perceived capacity for health promotion was measured on a 10-point Likert scale. Facilitators and barriers related to health promotion and aspects of child health prioritised for health promotion in the 2 years after restrictions eased were explored via closed- and open-ended questions. RESULTS: Of the 595 responses, 493 were eligible for analysis. Participants were based in schools in every county in the Republic of Ireland, with most (85.4%, n421) being female. Almost a third (30.5%, n150) were 11-20 years post-qualification, and a quarter (25.2%, n124) had over 30 years' teaching experience. Mean capacity for school-based health promotion pre-pandemic was moderate, at 6.6 ± 2.2 on a 10-point scale. Mean capacity in spring 2022 decreased significantly (p < 0.001) to 4.1 ± 2.4, indicating poor capacity. Capacity ratings did not significantly differ by school type (p = 0.31), socioeconomic designation (p = 0.27) or years post-qualification (p = 0.08). Capacity decrements were most frequently (49.7%, n245) attributed to organisational factors, while individual and community-level factors were cited by 27.6% (n136) and 21.5% (n106) of respondents, respectively. Healthy eating significantly (p < 0.001) decreased as a priority for health promotion between pre-pandemic times (76.3%, n376) and spring 2022 (23.1%, n114). Mental health significantly (p < 0.01) increased as a priority, being listed by 38.1% (n188) as a priority pre-pandemic and doubling to 72.6% (n358) in spring 2022. CONCLUSIONS: Fostering a holistic approach to health promotion in schools remains a challenge. Further efforts are needed to support schools to implement sustainable and balanced systems of health promotion.

Contribution of orthography to vocabulary acquisition in a second language: Evidence of an early word-learning advantage in elementary-school children.

Recent studies have shown that children benefit from orthography when learning new words. This orthographic facilitation can be explained by the fact that written language acts as an anchor device due to the transient nature of spoken language. There is also a close and reciprocal relationship between spoken and written language. Second-language word learning poses specific challenges in terms of orthography-phonology mappings that do not fully overlap with first-language mappings. The current study aimed to investigate whether orthographic information facilitates second-language word learning in developing readers, namely third and fifth graders. In a first experiment French children learned 16 German words, and in a second experiment they learned 24 German words. Word learning was assessed by picture designation, spoken word recognition, and orthographic choice. In both experiments, orthographic facilitation was found in both less and more advanced readers. The theoretical and practical implications of these findings are discussed.

The effect of a Schema-based method on correcting persistent errors in mental arithmetic: an experimental study.

Introduction: Arithmetic calculation is a fundamental skill for mathematical learning and daily life. However, elementary school students often make errors in practice. Methods: Grounded in the schema theory and the memory retrieval theory of mental arithmetic, this study employs a controlled experiment to investigate the effect of a schema-based method in correcting persistent errors in mental arithmetic, specifically in the context of simple addition operations. The experimental group utilizes a schema-based method to help participants rectify incorrect answers in memory retrieval, while the control group did not receive this treatment. Results: The results showed that significant differences emerged between the experimental and control groups in both the post-test performance and the reduction of persistent error count, indicating that the experimental group had rectified incorrect answers in memory; and persistent errors in simple addition were indeed caused by interference from incorrect answers during memory retrieval; and the schema-based method proves to be effective. Discussion: The findings of this study contribute to enhancing practical mental arithmetic instruction, assisting students in correcting relevant errors, and improving their mental arithmetic abilities. Not only does it offer directive guidance for teaching practices, but it also provides an enlightening reference for promoting innovative teaching methods.

Prevalence of osteochondritis dissecans of the capitellum in elementary school baseball players based on ultrasonographic screening: a 15-year overview in Tokushima, Japan.

Background: Although several operative procedures have evolved for capitellar osteochondritis dissecans (OCD), the best outcome is achieved by early detection and conservative treatment. The objective of this study was to clarify changes in the prevalence of capitellar OCD in young baseball players over a long-term period based on consistent criteria in Tokushima, Japan between 2006 and 2020. Methods: The number of players who underwent screening and the discovery rate of capitellar OCD during the study period were investigated. School grade and radiographic stage were also evaluated. Results: The confirmation rate was significantly higher when ultrasonographic screening was performed than when screening was based on physical findings (65.8% vs. 1.9%, P < .001). The overall incidence of OCD in elementary school players based on ultrasonographic screening was 1.4% during the 10-year study period. Twenty-one (10.8%) of the 195 players identified to have OCD had experienced lateral elbow pain. When classified radiographically, the lesion was stage I in 73.3% of cases, stage II in 24.1%, and stage III in 2.6%. No cases of OCD were diagnosed before the fourth grade. The prevalence rates increased gradually from the fourth grade to the sixth grade. Conclusion: Ultrasonographic screening could be more effective for detecting capitellar OCD than screening based on physical findings. The overall prevalence of OCD among elementary school players was 1.4% over 10 years. The prevalence rates increased gradually from the fourth grade onwards.

The effect of student-perceived teacher support on math anxiety: chain mediation of teacher-student relationship and math self-efficacy.

Introduction: This study investigates the mechanisms linking students' perceived teacher support with math anxiety, focusing on the mediating roles of the teacher-student relationship and mathematics self-efficacy. Methods: The research was conducted with 401 fifth-grade students in China, utilizing scales for Students' Perceived Teacher Support, Teacher-Student Relationship, Math Self-Efficacy, and Math Anxiety. Results: Findings revealed that student-perceived math teacher support, teacher-student relationship, and math self-efficacy were all significantly negatively correlated with math anxiety. It was notably found that student-perceived math teacher support influenced math anxiety through the chain mediation of teacher-student relationship and math self-efficacy. Additionally, the effect of students' perceived emotional support from math teachers on math anxiety, mediated by teacher-student relationship intimacy, was significant only among male students. Discussion: These results underscore the importance of fostering positive teacher-student interactions and enhancing self-efficacy to reduce math anxiety among primary school students. The gender-specific findings regarding emotional support and relationship intimacy highlight the need for tailored strategies in addressing math anxiety.

Executive functions and problem-solving-The contribution of inhibition, working memory, and cognitive flexibility to science problem-solving performance in elementary school students.

Previous research has shown that executive functions can contribute to successful problem-solving in preschool and elementary school children. However, most studies did not simultaneously assess the role of different specific aspects of executive functions. Therefore, the aim of our study was to investigate the individual contribution of inhibition, working memory, and cognitive flexibility to science problem-solving performance in elementary school children. A total of 478 children from first and second grades (Mage = 7.44 years) participated in our study. They performed a Go/No-go task (inhibition), a Corsi blocks backward task (working memory), a flexible item selection task (cognitive flexibility), and three science problem-solving tasks, including two gear turning tasks and one stabilization task. Structural equation modeling showed that working memory and cognitive flexibility individually contributed to problem-solving performance, whereas inhibition did not. We conclude that maintaining task requirements and dynamic object relations (working memory) and switching between different problem-solving phases (cognitive flexibility) are essential components of successful science problem-solving in elementary school children. Inhibitory processes may be more relevant in tasks involving a higher degree of interference at the task or response level.

Differences in walking and running parameters in elementary school students with and without backpacks.

BACKGROUND: Backpack syndrome (BS) is a term used to describe symptoms such as shoulder and back pain that are believed to be caused by carrying a backpack. Few studies have investigated the changes in walking and running parameters with and without backpacks. OBJECTIVE: The present study aimed to investigate the differences in walking and running parameters with and without backpacks in primary school children with and without BS. METHODS: This cross-sectional study included 51 children (average age 9.3 years, 6- 12 years). Two questions were asked beforehand: whether the respondents had shoulder or back pain when going to school and present; those who answered that they had pain in both cases were defined as the BS group, while the others were the control group. Walking and running at comfortable speeds and walking and running with a 6 kg backpack on their backs were measured. RESULTS: During walking, there were main effects for speed, cadence, and strike angle with and without the backpack, but no interactions were identified for any of the parameters. In running, however, there were main effects for speed, stride length, strike angle, and lift-off angle, and an interaction effect was observed for speed and stride length. CONCLUSIONS: During walking, carrying a 6 kg backpack increased cadence and walking speed. During running, carrying a backpack caused a decrease in stride length and running speed in the BS group, whereas there was no change in the control group, suggesting that the control and BS groups may respond differently.

Reliability and validity of simple Chinese version of grit scale for elementary school students.

BACKGROUND: The Grit scale (GS-12) is a widely used rating scale that assess passion and perseverance. The present study aimed to evaluate the reliability and validity of simple Chinese Version of Grit Scale (GS-SC) among Chinese adolescents. METHODS: Seven hundred one primary school students were recruited as Sample 1. Item analysis and exploratory factor analysis (EFA) were conducted on Sample 1 to preliminarily examine the structure of the scale. Sample 2 consisted of 5,384 primary school students. Confirmatory factor analysis (CFA) and verification of reliability and validity were conducted on Sample 2 to establish a formal scale and further verify the psychometric properties by applying item response theory (IRT). RESULTS: EFA and CFA revealed a clear two-factor structure. The results demonstrated that the Simplified Chinese Version of Grit Scale had adequate internal consistency and re-test reliability. GS-CS also showed good criterion-validity with personality, self-control, effort regulation and academic achievement. Furthermore, all the items show a acceptable fit to the GRM and have good discrimination (ranging from 2.13 to 3.45) and moderate difficulty(ranging from-1.58 to 0.95). CONCLUSIONS: The reliability and validity of the GS-SC are good, indicating that the scale can be used as an effective tool for measuring the grit of primary school students in China.

The role of handwriting in English word acquisition among elementary students.

In order to investigate whether handwriting has an advantage in learning word form, sound, and meaning, this study randomly selected 40 elementary school student participants (20 males, 20 females, aged 11.4 ± 1.34 years). Using an experimental approach, we compared the learning outcomes of word sound matching, word meaning matching, and word form judgment tasks under two conditions: handwriting and visual learning. After three consecutive days of learning and testing, we found that handwriting generally outperformed visual learning in terms of accuracy and response time in word form, sound, and meaning learning. Additionally, we observed differences in the timing of significant discrepancies in learning outcomes between the two methods across the three tasks. Specifically, in terms of accuracy, discrepancies first appeared in the word sound matching task on the first day, followed by the word form judgment task, and lastly the word meaning matching task. Regarding response time, significant differences between learning methods first emerged in the word form judgment task, followed by the word sound and word meaning tasks. Thus, combining accuracy and response time data, we conclude that handwriting is more advantageous than visual learning for word acquisition, with a differential impact on word form, sound, and meaning, where word form and sound are prioritized over meaning.

Relationship between the floating toe and the center-of-pressure position in an upright posture among students.

[Purpose] The incidence of floating toes in children is increasing. Although the anteroposterior center of pressure in children is present posteriorly, its relationship with the floating toe is unclear. This study aimed to clarify the relationship between the position of the anteroposterior center of pressure and the floating toe in an upright posture in children. [Participants and Methods] In this cross-sectional study, a Win-Pod (Medicapteurs) platform was used to measure the position of the anteroposterior center of pressure in 208 boys and 195 girls from Japanese elementary schools. Using images of the plantar footprint, floating toes were assessed and the floating toe score was calculated. [Results] The anteroposterior center of pressure position was situated 32.3 ± 8.2% from the heel. The floating toe score of all the participants was 3.5 ± 2.4, with a very high rate of 98%. The floating toe score had a significant, moderate correlation with age, height, weight, and the anteroposterior center-of-pressure position. Multivariate analysis revealed an association between the floating toe score and the anteroposterior center-of-pressure position, height, and weight. [Conclusion] There is significant relationship between the anteroposterior center-of-pressure position and the floating toe score in an upright posture in Japanese elementary school students.

Reading processes of public and private middle school and high school students.

INTRODUCTION: Reading has been widely discussed, mainly due to the published results of international performance tests of schoolchildren. The gaps generated in literacy hinder the development of basic skills necessary for reading, which will have a negative impact on the teaching-learning process from elementary school to high school. This study aimed to compare the reading performance of the students in public and private schools through tests of the Brazilian reading processes-PROLEC-SE-R. METHODS: Cross-sectional study. The Brazilian adaptation of the PROLEC-SE-R was administered to 436 students: 221 from the state school (G1 6th year, n = 30; G2 7th year, n = 33; G3 8th year, n = 35; G4 9th year, n = 31; G5 1st year, n = 32; G6 2nd year, n = 30; G7 3rd year, n = 30) e 215 private schools (G8 6th year, n = 31; G9 7th year, n = 31; G10 8th year, n = 30; G11 9th year, n = 31; G12 1st year, n = 30; G13 2nd year, n = 31; G14 3rd year, n = 31). Tools of descriptive and bivariate analysis were used. RESULTS: Superior performance of the private school students on spelling tests helps their reading as evidenced by their scores for syntactic and semantic processes. When the knowledge of the use of the word in text, extraction of meaning and its understanding was needed, the difficulty of access to the mental lexicon of the studied population became evident. CONCLUSION: The PROLEC-SE-R, in addition to establishing the reading profile of elementary and high school students, shows that the gaps in teaching and learning, which exist between public and private education in the literacy period, accompany students throughout the basic education cycle. Knowing the reading profile and in which process there is a disruption is important so that the teaching of specific strategies can be promoted throughout the entire schooling process, especially in primary and secondary education.

Improving Recess through Collaboration: Exploring the Facilitators and Barriers to Sustaining Positive Playground Behavior.

BACKGROUND: School recess quality is vital to children's social and emotional skill development. However, there is a research-to-practice gap where academic findings are ineffectively translated back to schools. The aims of this study were to examine how a co-designed intervention would impact negative behaviors observed during recess and to explore the facilitators and barriers to recess implementation over the course of a school year. METHODS: Utilizing a research-practice partnership, the authors collaborated with staff at an elementary school to design, implement, and assess an intervention focused on improving recess quality. The intervention offered training in research-supported recess practices through professional development training and teaching students transitions and games. The school's recess behavioral report log of negative playground behaviors across the academic year and notes from recess staff meetings were analyzed. RESULTS: Quantitative results pointed to a stable decrease in negative playground behaviors post-intervention compared to pre-intervention. Qualitative analyses suggest school leadership and practitioners should focus on "reculturing" recess prior to making structural changes, and empowering recess staff to sustain change. CONCLUSION: Prior to considering interventions at recess, there is a need to assess both school and recess culture. In doing so, reculturing around the importance of recess during the school day and the roles of adults in the process is needed to ensure the sustainability of any changes made.

Prevalence and Factors Associated with Sickness Presenteeism among Thai and Foreign Teachers Following the End of COVID-19 Public Health Emergency of International Concern.

Background: Sickness presenteeism (SP) refers to the phenomenon where employees attend work while sick, a decision that impacts both their physical and mental well-being and can lead to burnout. This study aimed to determine the prevalence of and factors influencing SP among Thai and foreign teachers following the end of the coronavirus disease 2019 public health emergency of international concern (PHEIC). Methods: A sample of 400 individuals was analyzed using chi-square tests and logistic regression to obtain odds ratios (ORs) and 95% confidence intervals (CI). Results: Post-PHEIC, a significant proportion of teachers (51.9%) perceived an increase in their workload, and 62.1% reported having taken health-related leave of absence. The prevalence of SP was high (35.0%). Factors significantly associated with SP (P<0.05) included being younger than 37 years (OR, 1.825; 95% CI, 1.108-3.006), facing monthly financial challenges (OR, 1.627; 95% CI, 1.028-2.575), doing school-related work on holidays (OR, 1.920; 95% CI, 1.180-3.122), and experiencing sleep disturbances owing to work-related stress (OR, 1.910; 95% CI, 1.203- 3.033). No discernible difference existed in SP rates between Thai and foreign teachers. Conclusion: As a course of action, we recommend the provision of appropriate financial planning resources for teachers. Policywise, school events and activities should be scheduled on working days to ensure that teachers maintain a work-life balance. Additionally, task allocation that caters to individual strengths and limitations can mitigate the effects of SP.

Changes in the Average Body Mass Index of Fifth- and Sixth-Grade Korean Elementary School Students: The Role of Physical Education in Student Health.

This study aimed to emphasize the importance of physical education in maintaining sufficient physical activity by examining the average BMI of fifth- and sixth-grade elementary school students in Korea over multiple years. This study investigated changes in the average BMI of fifth- and sixth-grade elementary school students in Korea. It provided foundational data to suggest the role of physical education in student health and set future directions. The 2019-2021 Physical Activity Promotion System (PAPS) of the Korean Ministry of Education was used. Data corresponding to fifth- and sixth-grade students (124,693 from 2019, 126,226 from 2020, and 117,809 from 2021) in 1208 elementary schools in Korea were collected. Repeated measures ANOVA was conducted for the data analysis. The study findings are as follows: First, the average BMI of fifth- and sixth-grade elementary school students in Korea increased significantly in 2021 compared with 2019 and 2020. Second, changes in the yearly average BMI showed a significant difference depending on gender and grade. Obesity among fifth- and sixth-grade elementary school students in Korea increased steadily during 2019-2021, which may be due to a decrease in students' physical activity. Male students showed a steeper increase regardless of grade. During the study period, limited physical activity at school increased obesity rates. Physical education must play a role in students' health in preparation for future changes.
