'We get to learn as we move': effects and feasibility of lesson-integrated physical activity in a Swedish primary school.

BACKGROUND: Physical activity (PA) promotes health in adults as well as children. At the same time, a large proportion of children do not meet the recommendations for PA, and more school-based efforts to increase PA are needed. This study investigates the effectiveness and feasibility of lesson-integrated PA in a Swedish primary school. METHODS: We evaluate a new method called 'Physical Activity and Lesson in Combination' (abbreviated FALK in Swedish) using a mixed methods approach; a quasi-experimental study followed by qualitative interviews. Two schools participated in the study, one constituting the intervention group (I-school, n = 83) and the other the control group (C-school, n = 81). In addition to regular physical education, the I-school had three 30-minute FALK lessons each week. A total of 164 students aged 7-9 years wore pedometers for a whole week, four times over two semesters, and the number of steps per day (SPD) and the proportion of students with < 10,000 SPD were compared. Statistical differences between the schools were tested with ANOVA, Chi2, t-tests, and ANCOVA. Interviews with students (n = 17), parents (n = 9) and teachers (n = 9) were conducted and analysed using qualitative content analysis. RESULTS: The results show that FALK led to the I-school getting more SPD and fewer students with < 10,000 SPD. Also, FALK was experienced as a positive, clear, and flexible method, simultaneously encouraging PA and learning. Challenges experienced concerned the teachers' work situation, time, finding suitable learning activities, outdoor school environment changes, and extreme weather conditions. CONCLUSIONS: This study indicates that FALK has the desired effects on PA and is a feasible method of integrating PA into theoretical teaching. We conclude that FALK is worth testing at more schools, given that implementation and sustainment of FALK considers both general enablers and barriers, as well as context-specific factors at the individual school.

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.

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.

The Effects of Family and School Interpersonal Relationships on Depression in Chinese Elementary School Children: The Mediating Role of Academic Stress and the Moderating Role of Self-Esteem.

This study explores the relative contributions and psychological mechanisms of the effects of family (father-child and mother-child) and school (teacher-student and student-student) interpersonal relationships on depression in elementary school children. The participants (n = 20,629) were elementary school children (48.19% male) aged nine to 13 years from Southwest China during the COVID-19 pandemic. They voluntarily completed questionnaires regarding parent-child, teacher-student, and student-student relationships, as well as academic stress and self-esteem. The results indicate that the effect of family interpersonal relationships on children's depression was stronger than that of school interpersonal relationships. The predictive effects of father-child and mother-child relationships on children's depression did not significantly differ; however, the effect of student-student relationships was significantly stronger than that of teacher-student relationships. Academic stress partially mediated the effect of interpersonal relationships on depression in elementary school children. The effects of family interpersonal relationships and academic stress on depression were moderated by self-esteem. These findings underscore the disparities and mechanisms pertaining to the impacts of diverse interpersonal associations on children's depression, thus signifying significant implications for the advancement of research and intervention strategies aimed at addressing this issue.

The Joint Operations of Teacher-Student and Peer Relationships on Classroom Engagement among Low-Achieving Elementary Students: A Longitudinal Multilevel Study.

Although both teacher-student relationship (TSR) and peer relationship (PR) have been found important for the development of students' classroom engagement, little research has been done regarding the joint operations of these two factors. Guided by a developmental systems framework, this study examined longitudinal between-person and within-person associations between TSR/ PR and classroom engagement in a sample of 784 low-achieving students in the first three years of elementary school. A multidimensional approach was used to distinguish positive and negative dimensions of TSR, as well as peer liking and disliking. At the between-person level, results showed that students' classroom engagement was positively predicted by positive TSR and PR liking and was negatively predicted by negative TSR and PR disliking. Both positive and negative TSR interacted with PR disliking at the between-person level, such that the associations between positive/negative TSR and classroom engagement were stronger for students with lower levels of PR disliking. At the within-person level, changes in classroom engagement were associated with contemporaneous year-to-year changes in positive/negative TSR and PR disliking. No within-person level interaction effects were found. Cross-level interaction showed that the effects of within-person negative TSR on classroom engagement were stronger for students with lower overall levels of PR disliking. Findings highlighted the importance of using a multilevel multidimensional approach to understand the joint operations of TSR and PR in the development of classroom engagement in low-achieving students in early elementary school.

The social contexts of behaviors and relationships: The relation of classroom and cyber victimization to number of classroom and cyber friends.

Behaviors and relationships exist within a variety of social contexts. More specifically for the current research, victimization and friendships occur in classrooms and, increasingly, in online virtual contexts. The current research examined how the number of classroom friends and number of cyber friends related to the extent of classroom victimization and extent of cyber victimization. Research has demonstrated the importance of face-to-face friendships in relation to being a victim; much less is known about the role of cyber friends in relation to being a cyber victim or how these relationships may play a role in cross-context victimization. Participants were 350 children from Grades 3 through 5 (188 girls and 162 boys). Children indicated classroom friends on a classroom roster, reported the number of their cyber friends, and indicated the extent of their cyber victimization. Peers nominated classmates for classroom victimization behaviors. A path analysis revealed that number of classroom friends was negatively associated with both extent of classroom victimization and extent of cyber victimization. Number of cyber friends was positively associated with extent of cyber victimization and was negatively related to extent of classroom victimization. Discussion of results includes the construction, use, and adaptation of social skills within and between social contexts.

The Prevalence of Central Auditory Processing Disorder in Elementary School Students of Kerman, Iran.

Objectives: This study aimed to determine the prevalence of central auditory processing disorder (CAPD) in elementary school students in Kerman, Iran, during 2018-2019. Materials & Methods: This cross-sectional study was conducted on 1369 elementary school students in Kerman. These students were selected by cluster sampling from different areas of Kerman and then screened using the Buffalo Model Questionnaire (BMQ). Based on the data obtained from the questionnaire, normal children were excluded from the study. Then, children with suspected central auditory processing disorder (CAPD) underwent ear exams and were excluded from the study in case of abnormal results in the tympanic membrane examination (rapture-effusion). The remaining subjects underwent peripheral audiometry evaluation, and children with abnormal audiometry were excluded from the study. Finally, the remaining children with suspicious screening results, a normal examination, and normal audiometry underwent a specific test to detect Central auditory processing disorder. Data analysis was carried out using SPSS software. Results: One thousand three hundred sixty-nine primary school students with a mean age of 9.15 ±2.63 years enrolled in this study. 52%% of students were male. 8.03% of them had CAPD. A statistically significant relationship was found between the prevalence of CAPD and gender (P<0.001), place of residence (P<0.001), history of middle ear inflammation (P<0.001) and history of head injury. Conclusion: The quality of life of these students with CAPD can be improved via timely recognition of CAPD and the provision of appropriate preventive and therapeutic facilities.

Relations between the levels of moderate to vigorous physical activity, BMI, dietary habits, cognitive functions and attention problems in 8 to 9 years old pupils: network analysis (PACH Study).

BACKGROUND: Physical activity (PA) and dietary habits (DH) play a crucial role on quality of life and health outcomes from various aspects. METHODS: This study aims to investigate the relations between recommended daily levels of moderate to vigorous physical activity (MVPA) in 8 to 9 year old pupils, and their body mass index (BMI), DH, cognitive functions and attention problem scores by network analysis. Study participants were split into two groups based on their MVPA levels on weekdays. RESULTS: Our findings suggest that children who reach recommended MVPA levels consume more vegetables and fruits, eat breakfast more frequently, have better motor speed and lower impulsivity score. CONCLUSIONS: The number of interlinkages between various parameters in network structure for children who do not reach recommended MVPA levels is greater and more intense, highlighting the differences between the groups and suggesting that different interventions and approaches to improve/change lifestyle habits might be used.

Teaching happiness to students - implementation and evaluation of a program aiming at promoting wellbeing in elementary schools.

Since the beginning of the COVID-19 pandemic, the prevalence of mental disorders in children and adolescents has increased significantly. Evidence shows that childhood mental disorders can have serious consequences on psychosocial, cognitive, and physical development. Approaches from Positive Education go further than the urgently needed prevention of mental disorders by aiming directly at promoting subjective, psychological, and social wellbeing. The present study describes the implementation of a brief program to promote wellbeing in 15 elementary schools. For this purpose, in a regular university seminar, students of teaching and educational science were instructed to give 11 "happiness lessons" for fourth graders in a team of two and in the presence of the class teacher over the course of 3 months. Quantitative data were collected from children and parents in the treatment group classes and in the parallel classes serving as the waiting control group at four measurement points (pre, post, 1- and 2-month follow-up). We assessed psychological wellbeing, negative emotions and moods, parent support and home life, perception of the school environment, and self-esteem of the children with established instruments with versions for children and their parents and the frequency of positive and negative emotions of the children in self-report only. Additionally, we applied ad hoc items on subjective perception of the project and open questions in the treatment group. Data were analyzed with EffectLiteR using multigroup structural equation models. Results showed a small significant effect for negative emotions with the children's data and a medium effect for psychological wellbeing in the perception of the parents at the 1-month follow-up. Interaction effects suggest that lower baseline levels in parent support and home life and self-esteem would increase the treatment effect for these constructs. The need for more grounded framework in positive education and the inclusion of more qualitative methods as well as suggestions to improve the program in the sense of a whole school approach are discussed.

The personal epistemology of parents predicts the development of scientific reasoning in children aged 6-10 years.

The influence of the epistemological beliefs of parents on the development of comprehensive scientific reasoning abilities was investigated in a five-wave longitudinal study from kindergarten to elementary school. The 161 German 5-10-year-olds (89 girls, 72 boys) were assessed yearly on their scientific reasoning abilities using comprehensive measures for experimentation and data-interpretation skills, as well as understanding of the nature of science. The children were also tested on their language abilities and intelligence. Their parents completed a sociodemographics questionnaire and answered ten questions about their epistemological beliefs regarding (1) the interpretive nature of science, (2) the tentative nature of knowledge, and (3) the role of scientific framework theories. The personal epistemology of the parents significantly predicted the scientific reasoning development of their children regardless of the parents' education level and the children's general cognitive abilities. However, the effect of the epistemology of parents on their children's scientific reasoning was limited to the intercepts, suggesting that the epistemic understanding of parents affects how scientific reasoning develops in their children, but not the development speed. Although parental epistemology exerts substantial effects on scientific reasoning of their children, it did not affect their reading ability, suggesting an involvement of science-specific mechanisms rather than generalized family-based influences. These findings highlight the importance of family as a variable in the development of scientific reasoning, which is an area lacking in research, and it suggests that early interventions targeted at the epistemic understanding of caregivers can provide useful ways for promoting the reasoning of children. RESEARCH HIGHLIGHTS: A five-year longitudinal study shows significant development of scientific reasoning from kindergarten to elementary school. Caregivers' personal epistemology predicted scientific reasoning development-independent of children's general cognitive abilities and caregivers' level of education. The effect was most-pronounced for caregivers' understanding that social framework theories determine which aspects of science are accepted and how they are conducted. Caregivers' personal epistemology did not predict children's reading abilities, suggesting that the effect of the caregivers' epistemology on children's scientific reasoning is domain-specific.

A Parallel Process Growth Curve Analysis of Teacher-Student Relationships and Academic Achievement.

Teacher-student relationships (TSR) have been a key focus of study for developmental and educational psychology researchers interested in improving proximal and distal academic outcomes for children and youth. Although prior empirical work suggests some degree of association between TSR and achievement, the co-development of TSR and achievement during elementary grades remains unclear with most findings limited to reading and mathematics achievement. The current study used parallel process growth curve models (PPGCMs) to examine the longitudinal growth trajectories of teacher-student closeness and conflict, and science, reading, and mathematics achievement simultaneously for children followed from kindergarten to third grade in the Early Childhood Longitudinal Study, Kindergarten Class of 2010-2011 (N = 13,490). Findings from the final PPGCM showed teacher-student closeness in kindergarten was positively associated with science, reading and mathematics achievement in kindergarten (r = 0.234 to 0.277) and the linear growth of achievement through third grade (r = 0.068 to 0.156). Teacher-student conflict in kindergarten was negatively associated with science, reading, and mathematics achievement in kindergarten (r = -0.099 to -0.203) and the linear growth of achievement through third grade (r = -0.081 to -0.135). Child biological sex, family socioeconomic status, and child racial and ethnic identity predicted TSR and achievement developmental trends. Implications of the findings and future directions for research are discussed.

Funções neuropsicológicas de escolares na reabertura das escolas brasileiras na pandemia da Covid-19 / The neuropsychological functions of schoolchildren after the reopening of brazilian schools during the Covid-19 pandemic

RESUMO Objetivo O objetivo desse estudo foi analisar as funções neuropsicológicas de estudantes de uma escola pública do Distrito Federal (Brasil), matriculadas 1º e 2º ano de Ensino Fundamental na reabertura das escolas públicas na pandemia da COVID-19 e a influência dos fatores familiares e contextuais sobre o desempenho dessas habilidades. Métodos Participaram 117 estudantes, bem como seus responsáveis. As crianças foram avaliadas presencialmente por meio do Instrumento de Avaliação Neuropsicológica Breve Infantil (NEUPSILIN-Inf). Os pais/responsáveis responderam remotamente ao Inventário de Recursos do Ambiente Familiar e as questões para classificação socioeconômica e de escolaridade materna. Resultado Os dados apontam alta prevalência de crianças em fase de alfabetização que apresentam alerta ou déficit das funções de orientação, memória, linguagem, habilidades visuoespaciais, habilidades aritméticas e fluência verbal. Ainda, as atividades previsíveis que sinalizam algum grau de estabilidade na vida familiar são preditoras do desempenho das crianças na habilidade de orientação e os recursos que promovem processos proximais refletem significativamente no desempenho em linguagem. Os resultados sugerem que crianças inseridas em família com estimativas da renda domiciliar abaixo de um salário mínimo apresentam piores desempenhos do controle inibitório. Conclusão Foram apresentados e discutidos os impactos das alterações das habilidades neuropsicológicas para o aprendizado das crianças, destacando a necessidade de intervenções imediatas e direcionadas para essas funções. Foram considerados os fatores contextuais que apresentaram influência sobre o desempenho das habilidades neuropsicológicas.

ABSTRACT Purpose The objective of this study was analyzed the neuropsychological functions of students from a public school in Brazil, enrolled in the 1st and 2nd year of Elementary School at the time of the reopening of schools during the COVID-19 pandemic and to access the influence of family and contextual information on the performance of these skills. Methods 117 students participated in the study, as well as their parents or guardians. The children were evaluated in person using the Brief Child Neuropsychological Assessment Instrument (NEUPSILIN-Inf). The parents/guardians answered remotely the Inventory of Resources of the Family Environment and questions about socioeconomic classification and maternal education. Results The data showed a high prevalence of children who had problems or deficits in the functions of orientation, memory, language, visuospatial skills, arithmetic skills and verbal fluency. Furthermore, predictable activities that signal some degree of stability in family life are predictors of children's performance in orientation skills and resources that promote proximal processes significantly reflect on language performance. The results suggest that children included in families with a household income below one Brazilian minimum monthly salary presented poorer inhibitory control performances. Conclusion The impact of changes in neuropsychological skills in children's learning were presented and discussed, highlighting the need for immediate and targeted intervention of these functions. Contextual factors that influenced the performance of neuropsychological skills were also considered.

'What makes you say so?' Metacognition improves the sustained learning of inferential reading skills in English as a second language.

PURPOSE: This quasi-experimental study investigates the impact of enhancing metacognition in learning inferential reading skills in English as a second language. PROCEDURES: Six Grade 4 classes were randomly assigned to two groups. The "Control group" received an instructional unit on inferential reading skills. The "Metacognition group" received the same unit, including metacognitive activities. Students were assessed in metacognitive and inferential reading skills before (pre-test), immediately after (post-test) and four weeks after the intervention (deferred test). FINDINGS: Metacognitive strategy instruction enhanced student learning of inferential reading skills and its sustainability in time. The Metacognition group attained a significantly higher average score in deploying metacognitive skills both in the post and deferred tests, indicating that the intervention was effective, as intended, to this end. While both groups significantly improved their proficiency in inferential reading skills after working with the provided instructional unit, there was a significant difference in the Metacognition group, which outperformed the Control one, even more strongly in the deferred test. CONCLUSIONS: Findings support the importance of deliberately promoting metacognition as it positively impacts learning outcomes and sustainability.

A self-regulation intervention conducted by class teachers: impact on elementary students' basic psychological needs and classroom engagement.

Literature has reported a decrease in students' engagement throughout schooling, but more worrying, is that elementary students already show signs of disengagement. This data sets the case to develop interventions at this school level. The narrative-based intervention "Yellow Trials and Tribulations" aimed to promote self-regulation has been proven to positively impact elementary students' school engagement. Acknowledging that classroom engagement is expected to be more closely related to learning and achievement than school engagement, the current study aims to extend the research of the mentioned intervention on elementary students' classroom engagement (i.e., behavioral, emotional, cognitive, and agentic dimensions), as well as on basic psychological needs (i.e., perceived autonomy, competence, and relatedness)-an antecedent of students' engagement. The current intervention was implemented by 4th-grade class teachers trained for that purpose and was assessed following a quasi-experimental design with pretest and posttest data collection. Participants were 90 students in the experimental group, and 91 in the comparison group. A multivariate analysis of variance with repeated measures was run for each construct. At the end of the intervention, children in the experimental group reported higher perceived competence and classroom engagement (all dimensions) than their counterparts in the comparison group (small and medium effect sizes were found). No follow-up was conducted to examine whether the intervention effects were long-lasting. Results are expected to support researchers' and educators' efforts to effectively implement the intervention, and maximize its benefits to students. For example, extra efforts could be made to help implementers better respond to students' psychological needs (in this case, perceived autonomy and relatedness), and consequently increase classroom engagement (especially behavioral and emotional engagement, which revealed lower effect sizes).

Developmental trajectories of school-beginners' ability self-concept, intrinsic value and performance in mathematics.

BACKGROUND: Although research clearly demonstrates the importance of motivation in mathematics learning, relatively little is known about the developmental dynamics between different facets of mathematics motivation and performance, especially in the early years of schooling. AIMS: In a longitudinal setting, we examined (1) how children's ability self-concept and intrinsic value in mathematics change over time during their first 3 years in school, (2) how those changes relate to each other and (3) how they connect with mathematics performance. SAMPLE: The participants were 285 Finnish school-beginners (52.7% girls). METHODS: Latent growth curve modelling was used to examine the developmental trajectories of children's ability self-concept and intrinsic value, and how those trajectories predicted later mathematics achievement (both mathematics test performance and teacher-rated grades), while controlling for previous mathematics performance and gender. RESULTS: The results showed significant decreases in children's ability self-concept and intrinsic value, but also significant individual differences in the trajectories. The strong dependency between the levels and changes in self-concept and intrinsic value led us to specify a factor-of-curves latent growth curve model, thus merging the trajectories of ability self-concept and intrinsic value into one common model. Subsequent results showed prior mathematics performance to predict change in children's mathematics motivation, and both the level and change in mathematics motivation to predict third-grade performance and teacher-rated grade. CONCLUSIONS: Our findings provide evidence for a developmental link between children's ability self-concept, intrinsic value and achievement. Achievement seems to enhance mathematics motivation, and positive motivation appears to support the further development of mathematics skills.

The Developmental Progression of Early Algebraic Thinking of Elementary School Students.

Developing algebraic thinking in elementary school has gained consensus among mathematics educators. The objective of this study is to understand the developmental trajectory of early algebraic thinking in elementary school students so as to assist teachers and curriculum developers in implementing instruction that aligns with students' cognitive development. This study adopted a cross-sectional survey approach, involving 526 students from grades three to five in Shanghai, who were tested using a 12-item assessment that measured three aspects: "generalized arithmetic", "functional thinking", and "quantitative reasoning". Latent class analysis was used to analyze students' response strategies, and, in conjunction with individual interviews, this study identified potential developmental pathways in students' early algebraic thinking, progressing from "arithmetic thinking" to "concrete algebraic thinking", "generalized algebraic thinking", and finally to "symbolic algebraic thinking". As thinking levels advanced, significant differences in students' response strategies emerged, with notable improvements in "generalization abilities" and "symbolization abilities". This study suggests that educational practices should encompass content in elementary arithmetic curricula that fosters generalization abilities. Additionally, providing students with opportunities for diverse representations can effectively stimulate the development of early algebraic thinking.

Improving child nutrition in disasters by developing a modeled disaster preparedness nutrition education curriculum.

In contemporary global society, largely because of climate change and other natural and human-induced hazards, disasters are an almost daily occurrence. The nutritional impact of disasters on children results in long-term physical and mental health problems. As children are one of the most vulnerable demographic groups, they must be empowered with disaster preparedness nutrition knowledge, and the skills and motivation to survive, prevent/reduce malnutrition, and maintain good health during disasters. A disaster preparedness nutrition education program (DPNEP) was developed in this study to improve children's nutrition in daily life and during disasters through student-centered education. A consultative approach was used to synthesize the knowledge of a diverse group of four experts in disaster medicine and management, public health, education, and food and nutrition sciences to reach a consensus through discussion. A model DPNEP was developed by targeting grade 4 and 5 students and using interactive teaching methods. This can lead to the implementation of continuous nutrition education to empower children to make healthy food choices in daily life and reduce the risk of disaster-nutrition-related morbidity and mortality. Furthermore, once children acquire the necessary information, they are likely to share this knowledge with their families and communities, thereby enhancing society's resilience.

Mutual benefits for research and practice: Randomized controlled trials in the Hector Children's Academy Program.

This article describes how a series of randomized controlled trials (RCTs) were implemented in the Hector Children's Academy Talent Development Program with the goal of generating mutual benefits for research and practice. The Hector Children's Academy Program, founded in 2010 and located in one of the largest states in Germany, Baden-Württemberg, is a statewide enrichment program for talented primary school students, with a focus on STEMM topics. The program is financed by a private foundation, supervised by the Ministry of Education, and offered by 69 local sites that are hosted by local schools. About 15,000 primary school students (Grades 1-4) attend enrichment courses (more than 23,000 course participations) offered by the Hector Children's Academy Program every year. A unique element of the Hector Children's Academy Program is the role of empirical research in course development. The Hector Core Courses-offered by all local sites-undergo a strict quality assurance process in which RCTs are used to test their effectiveness with regard to central outcomes. After describing the Hector Children's Academy Program, we explain how the Hector Core Courses were developed and incorporated into the program, summarize key findings from the RCTs, and discuss mutual benefits for research and practice.
