Frontal P300 asymmetry and congruence judgment: Retroactive switching is impaired during school day mornings in female adolescents.

Investigating frontal EEG asymmetry as a possible biomarker of cognitive control abilities is especially important in ecological contexts such as school and work. We used a novel approach combining judgment performance and hemispheric frontal event-related potential (ERP) P300 asymmetry (fP3As) to evaluate aspects of cognitive control (i.e., repetition and switching) in adolescent females over a two-week ordinary school period. While undergoing electroencephalographic recording, students performed a word-colour "Stroop-like" congruence judgment task during morning and afternoon sessions, on Mondays and Wednesdays. Proportion of incongruence and congruence trials was 75% and 25%, respectively. ERP analysis revealed larger "novelty" right hemispheric fP3As amplitude for infrequent congruence but equivalent or significantly smaller than left hemispheric fP3As amplitude for frequent incongruence. RTs increased with extent of right fP3As shift. Behaviorally, repeat trial pairs (i.e., congruent followed by congruent, incongruent followed by incongruent) generally did not differ by time or day and were associated with near-ceiling accuracy. In contrast, switch trial pairs (i.e., congruent followed by incongruent, incongruent followed by congruent) in the afternoon were slower and associated with lower accuracy at the expected 75% criterion rate (i.e., judging incongruence by default), dropping significantly below 75% in the mornings. Crucially, compared to afternoon, morning fP3As patterns did not change adaptively with switch trial pairs. Although retroactive switching during congruence judgment was affected at all testing times, we conclude it was most impaired in the mornings of both early and mid school weeks, supporting misalignment between adolescent circadian cycle and school start time. We discuss some implications for optimal learning of adolescents at school.

Predicting Success: A Comprehensive Analysis of High School and Admission Test Scores on Future Academic Performance of Dental Students.

Introduction Dental school admissions in Pakistan traditionally rely on Higher Secondary School Certificate (HSSC), University of Health Sciences (UHS), and National Testing Service (NTS) scores, with limited research available on their predictive validity for dental school performance. This study aims to investigate the correlation between a student's first-year dental school performance and their HSSC, UHS, and NTS scores. Methods A total of 282 records, spanning the years 2016 to 2020, were obtained from a single private dental institution. The data included HSSC, UHS, and/or NTS scores, with the first professional examination results as the dependent variable. Statistical analysis was conducted using the Statistical Package for the Social Sciences (IBM SPSS Statistics for Windows, IBM Corp., Version 25.0, Armonk, NY), encompassing descriptive statistics, Pearson's correlation coefficients, and multiple regression analysis. Results Pearson's coefficients revealed weak to moderate positive correlations between the first professional examination and HSSC (r=0.209, p<.01), UHS (r=0.344, p<.01), and NTS (r=0.350, p<.01), all statistically significant at p < 0.01. Multiple regression analysis indicated that UHS scores contributed the highest explanatory power (R² = 0.146) in predicting first professional examination results. Conclusion A positive correlation between HSSC, UHS, and NTS scores with dental students' performance in the first professional examination is observed. However, the correlations are moderate, highlighting the importance of incorporating assessments that consider cognitive, behavioral, and skill-related aspects in admissions processes. Given the evolving landscape of dental education, these findings underscore the need for a holistic approach to identify candidates better equipped to serve the healthcare sector.

Association between maternal hemoglobin concentration and educational attainment in mid-childhood in a high-resource obstetric setting: a prospective cohort study.

BACKGROUND: Although maternal Hb levels during pregnancy are commonly associated with perinatal outcomes, their link to childhood neurodevelopment remains uncertain. OBJECTIVE: This study aimed to examine the associations between maternal hemoglobin (Hb) in early and late pregnancy with offspring mid-childhood educational attainment in a high-resource obstetric setting. STUDY DESIGN: Pregnancy data from a prospective birth cohort (Pregnancy Outcome Prediction Study, Cambridge, UK, 2008-2012, N=3285) were linked to mid-childhood educational outcomes (Department for Education, UK). Regression models adjusted for maternal, child, and socioeconomic factors were used to determine associations between maternal Hb, pregnancy complications, and offspring educational outcomes (ages 5-7). RESULTS: No association was observed between maternal Hb at 12 weeks and the likelihood of either adverse pregnancy outcomes or children meeting expected educational standards between ages 5-7. Higher maternal Hb at 28 weeks was associated with an increased risk of small-for-gestational age infants (aOR1.26, 95%CI 1.11-1.59; p=0.002) and preterm birth (aOR1.38, 95%CI 1.11-1.81; p=0.005). There were no adverse birth outcomes associated with anemia. However children of mothers who were anaemic at 28 weeks had ∼40% increased risk of not attaining expected educational standards at age 5 (aOR1.42, 95%CI 1.03-1.95; p=0.03). There was no association between maternal anemia at 28 weeks and educational performance at ages 6-7. No associations were found between high maternal Hb concentrations (top decile) or change Hb concentrations between 12-28 weeks and childhood educational attainment. CONCLUSIONS: Maternal anemia at 28 weeks of pregnancy is associated with reduced educational attainment aged 5, but not at older ages (6-7 years). A proactive approach to increasing maternal hemoglobin in high-resource settings is unlikely to impact on long-term childhood educational attainment.

Differential effects of growth restriction and immaturity on predicted psychomotor development at 4 years of age in preterms.

BACKGROUND: Fetal growth restriction and immaturity are associated with poor neurocognitive development and child psychopathology affecting educational success at school and beyond. However, the differential effects of either obstetrical risk factor on predicted psychomotor development have not yet been deciphered. OBJECTIVE: This study aimed to separately study the impact of growth restriction and that of immaturity on predicted psychomotor development at the preschool age of 4.3 (standard deviation, 0.8) years using birthweight percentiles in a prospective cohort of preterm infants born at ≤37+6/7 weeks of gestation. Differences between small for gestational age newborns with intrauterine growth restriction and those without were described. We examined predicted total psychomotor development score, predicted developmental disability index, calculated morphometric vitality index, and predicted intelligence quotient, Porteus Maze test score, and neurologic examination optimality score in 854 preterm infants from a large prospective screening cohort (cranial ultrasound screening, n=5,301). STUDY DESIGN: This was a prospective cranial ultrasound screening study with a single-center cohort observational design (data collection done from 1984-1988, analysis done in 2022). The study included 5,301 live-born infants, of whom 854 (16.1%) were preterm infants (≤37+6/7 weeks' gestation), and was conducted on the day of discharge of the mother at 5 to 8 days postpartum from a level 3 perinatal center. Predicted psychomotor development, as assessed by the predicted total psychomotor development score, predicted developmental disability index, calculated morphometric vitality index, predicted intelligence quotient, Porteus Maze test score, and neurologic examination optimality score were calculated. We related psychomotor development indices and measures to gestational age in 3 groups of birthweight percentiles (ie, 10%, 50%, and 90% for small, appropriate, and large for gestational age newborns, respectively) using linear regression analysis, analysis of variance, multivariate analysis of variance, and t test procedures. RESULTS: The key result of our study is the observation that in preterm infants born at ≤37+6/7 weeks of gestation, growth restriction as compared with immaturity is the prime risk factor for impairment of overall predicted psychomotor development, intelligence quotient, Porteus Maze test results, and neurologic examination optimality score at the preschool age of 4.3 (standard deviation, 0.8) years (P<.001). This is particularly true for intrauterine growth restriction. These detrimental effects of growth restriction become more prominent with decreasing gestational age (P<.001). As expected, growth restriction in preterm infants born at ≤37+6/7 weeks of gestation was associated with a number of obstetrical risk factors, including hypertension in pregnancy (P<.001), multiple pregnancy (P<.001), pathologic cardiotocography (P=.001), and low pH (P=.007), increased pCO2 (P=.009), and poor pO2 (P<.001) in umbilical arterial blood. Of note, there were no differences in cerebral hemorrhage or white matter damage among small, appropriate, and large for gestational age birthweight percentile groups, suggesting an independent mechanism of brain injury caused by preterm growth restriction resulting in poor psychomotor development. CONCLUSION: Compared with immaturity, growth restriction in preterm infants has more intense detrimental effects on psychomotor development, necessitating improved risk stratification. This finding has implications for clinical management, parental consultation, and early intervention strategies to improve school performance, educational success, and mental health in children. The mechanisms of brain injury specific to growth restriction in preterm infants require further elucidation.

Exploring the link between perceived physical literacy and academic performance outcomes: insights from the EHDLA study.

Objective: The aim of this study was to verify the relationship between perceived physical literacy (PPL) and academic performance outcomes among Spanish adolescents aged 12-17 years. Methods: This cross-sectional study is a secondary examination utilizing data derived from the Eating Healthy and Daily Life Activities (EHDLA) project. The Spanish Perceived Physical Literacy Instrument for Adolescents (S-PPLI) was used to evaluate the PPL of the participants. To determine academic performance, the numerical grades for each subject were added together and then divided by the total number of subjects. Results: Overall, a positive trend in the association between S-PPLI scores and academic performance was observed. We identified two significant ranges within the S-PPLI scores. First, there was a significant range between 9 and 33 points on the S-PPLI, indicating an inverse association with academic performance. Second, another significant range was observed at scores of 34 points or higher on the S-PPLI, suggesting a positive association with academic performance. Participants with low PPL had the lowest academic performance (mean = 6.4; bias-corrected and accelerated (BCa) bootstrapped 95% confidence interval (CI): 6.2-6.6). Conversely, those adolescents with high PPL had the highest academic performance (mean = 6.9; BCa bootstrapped 95% CI: 6.6-7.1). Significant differences were found between low PPL and medium PPL (p-adjusted = 0.031) and between low PPL and high PPL (p-adjusted = 0.031). Conclusions: Increased physical literacy could be a relevant factor for achieving greater academic performance in adolescents. This study has potential implications for physical education instructors, school leaders, and healthcare practitioners.

Association between small-for-gestational age and poor school performance in 2 500 000 children born 1973-2002.

AIM: To examine the association between infant weight for gestational age and school performance when leaving school at 16 years of age. METHODS: Out of 2 525 571 infants born near- or at term, between 1 January 1973 and 31 December 2002, identified from the Swedish Medical Birth Register, 65 912 (2.6%) were born small-for-gestational age (SGA). Outcomes studied were the risk for the need for education in special school, and the final average grades. Modified Poisson regression analyses and weighted linear regression analyses were performed. RESULTS: An association between SGA and the need for a special school was found, irrespective of restrictions or adjustments (RR between 2.47 and 2.25). SGA was associated with final grades below the 10th and 25th percentile (RR 1.49 and 1.18, respectively). A linear relationship between maternal height and the RR for education in special school (p = 0.005), suggested that SGA is a stronger risk factor among children of tall than of shorter women. CONCLUSION: SGA increased the risk for poor school performance, and for the need for a special school. We found an association between maternal height and school performance in relation to birthweight, suggesting that maternal height should be considered when estimating the impact of SGA on later outcomes.

Assessment of quality of life, school performance, and physical activity in adolescents with Familial Mediterranean fever.

OBJECTIVES: The aim of this study is to evaluate differences in school performance, school attendance, quality of life, and physical activity in adolescents with Familial Mediterranean fever (FMF) compared to healthy controls. METHODS: One hundred and twenty-nine patients with FMF and 154 healthy controls between 13 and 18 years were included in the study. Demographic, school performance (according to grade point average), school absenteeism, and type and frequency of exercise were recorded. Quality of life was evaluated with the Pediatric Quality of Life Inventory (PedsQL) 4.0. RESULTS: The mean age of FMF patients was 15.1 ± 2.7 years, and 69 patients (53.5%) were female. School performance was significantly higher in the control group compared to FMF patients (P < 0.001). In the control group, there were significantly higher participants who engaged in professional sports (P < 0.001). Patients with FMF had significantly lower self-reported PedsQL scores in school functioning, physical, and psychosocial health domains compared to those in the control group (P = 0.001, P < 0.001, and P = 0.028, respectively). CONCLUSIONS: FMF patients demonstrated lower school performance and quality-of-life scores compared to healthy controls. In addition to improving symptoms in chronic diseases, it is important to evaluate and improve the quality of life of patients in routine practice and to ensure psychosocial well-being.

The relationship of children's dental clinical status with school performance and school attendance in the Kingdom of Bahrain: A life-course approach.

OBJECTIVES: To examine the association between dental clinical status and school performance and school attendance in the Kingdom of Bahrain (KoB) using a life-course framework. METHODS: This time-ordered cross-sectional study included 466 school children in Grade 2 (aged 7-8 years) and their parents in the KoB. Data were collected through parents' self-administered questionnaires, children's face-to-face interviews and dental clinical examinations. Data on children's school performance and school attendance were gathered from parents and school records. Structural equation modelling (SEM) examined the direct and indirect pathways between variables. RESULTS: Children born in families with high socio-economic status (SES) were less likely to have dental caries and more likely to have better school performance at 7-8 years of age. Dentine caries was directly linked with poor school performance. Treated teeth directly predicted high school performance. The presence of dentine caries mediated the relationship of SES with school performance. CONCLUSIONS: Birth and current socio-economic factors were significant predictors of dental clinical conditions and school performance. Dental caries and fewer treated teeth directly predicted poor school performance.

Associations between type 1 diabetes and educational outcomes: an Aotearoa/New Zealand nationwide birth cohort study using the Integrated Data Infrastructure.

AIMS/HYPOTHESIS: Type 1 diabetes is one of the most common chronic diseases of childhood. It is hypothesised that the metabolic and psychosocial consequences of type 1 diabetes may affect educational outcomes; however, existing literature presents conflicting results. This study aimed to assess whether educational outcomes differ for young people with and without type 1 diabetes in Aotearoa/New Zealand (NZ). METHODS: This was a nationwide 9 year birth cohort study of all people born in NZ from 1993 to 2001 using linked administrative data held within the Integrated Data Infrastructure, a national research database containing linked health and non-health data. Educational outcomes of high school attainment, high school attendance and university enrolment were measured from age 13 years until 20 years. Generalised linear regression models with log link and Gaussian distributions were used to compare educational outcomes between those with and those without type 1 diabetes, adjusting for sociodemographic and maternal characteristics. RESULTS: Of the 442,320 children in the birth cohort, type 1 diabetes was identified in 2058 (0.47%) (mean [SD] age of type 1 diabetes diagnosis 7.7 [3.4] years). Educational outcomes were significantly lower for children with type 1 diabetes than for those without type 1 diabetes, including for any high school qualification (RR 0.97 [95% CI 0.95, 0.99]), university entrance-level high school attainment (RR 0.88 [95% CI 0.84, 0.92]), regular high school attendance (RR 0.91 [95% CI 0.85, 0.97]) and university enrolment (RR 0.93 [95% CI 0.88, 0.98]), even after adjusting for sociodemographic and maternal factors. In addition, educational outcomes were substantially lower for those with post type 1 diabetes diagnosis hospitalisations for diabetic ketoacidosis and hypoglycaemia. CONCLUSIONS/INTERPRETATION: In this whole NZ birth cohort study, type 1 diabetes was associated with lower educational outcomes spanning secondary school and into university enrolment. Ongoing efforts to support students with type 1 diabetes are needed, particularly for those with a greater risk profile.

Problematic familial alcohol use and adolescent outcomes: Do associations differ by parental education?

Aim: To investigate the associations between problematic familial alcohol use and adolescent subjective health, binge drinking, relationships with parents, school performance, and future orientation, and to study whether these associations differ in relation to parental education. Methods: Cross-sectional data from the Stockholm School Survey (SSS) collected among students in the 9th and 11th grades in 2018 and in 2020 were used (n = 19,415). Subjective health, parent-youth relationships, and school performance were coded as continuous variables; binge drinking and future orientation were coded as binary variables. Familial drinking included three categories: problematic; don't know/missing; and not problematic. Parental university education distinguished between adolescents with two, one, or no university-educated parent(s). Control variables included gender, grade, family structure, migration background, parental unemployment, and survey year. Linear and binary logistic regression analyses were performed. Results: Problematic familial alcohol use was associated with worsened subjective health, a higher likelihood of engaging in binge drinking, worse relationships with parents, and a higher likelihood of having a pessimistic future orientation, even when adjusting for all control variables. Having less than two university-educated parents was associated with a higher likelihood of reporting problematic familial alcohol use. Parental university education moderated the association between problematic familial alcohol use and binge drinking as this relationship was stronger for adolescents with no and one university-educated parent(s). Conclusions: Adolescents with problematic familial alcohol use fared worse with regards to all studied outcomes, except for school performance. Parental university education only moderated the association between problematic familial alcohol use and binge drinking. However, since problematic familial alcohol use was more common among adolescents with less than two university-educated parents, we argue that at the group level, this category may be more negatively affected by alcohol abuse in the family. Policy interventions could benefit from having a socioeconomic perspective on how children are affected by alcohol's harms to others.

Polygenic Risk of Mental Disorders and Subject-Specific School Grades.

BACKGROUND: Education is essential for socioeconomic security and long-term mental health; however, mental disorders are often detrimental to the educational trajectory. Genetic correlations between mental disorders and educational attainment do not always align with corresponding phenotypic associations, implying heterogeneity in the genetic overlap. METHODS: We unraveled this heterogeneity by investigating associations between polygenic risk scores for 6 mental disorders and fine-grained school outcomes: school grades in language and mathematics in ninth grade and high school, as well as educational attainment by age 25, using nationwide-representative data from established cohorts (N = 79,489). RESULTS: High polygenic liability of attention-deficit/hyperactivity disorder was associated with lower grades in language and mathematics, whereas high polygenic risk of anorexia nervosa or bipolar disorder was associated with higher grades in language and mathematics. Associations between polygenic risk and school grades were mixed for schizophrenia and major depressive disorder and neutral for autism spectrum disorder. CONCLUSIONS: Polygenic risk scores for mental disorders are differentially associated with language and mathematics school grades.

Three approaches to modeling the relationship among durable goods, academic achievement, and school attendance in Colombia1.

In comparison to research on assets and their impact on school performance, less research has been devoted to household assets. This article studies the relationship among durable goods, academic achievement, and school attendance in Colombia. Durable goods are approximated through three different methodological approaches: inventory, attributional, and index approaches. Data come from the 2017 SABER test, a nationwide examination that assesses reading and math skills, for fifth- and ninth-grade students, (N = 621,218). Students with complete durable goods information (N = 364,436) were included. Multilevel modeling was used to test the effects of durable goods on academic achievement and school attendance. The results suggest that while the index approach provides a broad understanding of how durable goods relate to school performance, the inventory and the attributional approaches show that different types of durable goods have differential effects on educational outcomes. The index approach illustrates that the possession of durable goods is positively associated with academic achievement and school attendance. The inventory and the attributional approaches show that washing machines, computers, and internet access are positively related to academic achievement and school attendance. In contrast, TVs, video games, and cars are negatively related to school performance. This research added to the literature by using different methodological approaches to operationalize durable goods, and by expanding the geographic scope to Latin America. Findings from this study may contribute to reassessing current measures of multidimensional poverty in Colombia to include durable goods.

Which is the optimum parenting for adolescents with low vs. high self-efficacy? Self-concept, psychological maladjustmentand academic performance of adolescents in the Spanish context / ¿Cuál es el estilo parental óptimo para adolescentes con baja vs. alta autoeficacia? Autoconcepto, desajuste psicológico y rendimiento académico de los adolescentes en el contexto español

El objetivo de este estudio es identificar qué estilo parental se asocia con resultados óptimos entre los adolescentes de familias españolas considerando aquellos con baja vs. alta autoeficacia. Los participantes fueron 1029 adolescentes españoles, 453 varones (44%), de 12 a 17 años. Aunque los estudios clásicos identifican el estilo autorizativo (basado en el afecto y la severidad) como la mejor estrategia socializadora, las investigaciones emergentes cuestionan seriamente los beneficios de la severidad parental. Además, el impacto de la socialización parental en la competencia psicosocial del adolescente se ha estudiado durante años, pero se sabe menos sobre si podría variar en función de las características individuales del adolescente (e.g., la autoeficacia). Las familias fueron clasificadas por estilo parental (autorizativo, autoritario, indulgente o negligente), y los adolescentes por baja vs. alta autoeficacia. La competencia psicosocial se examinó a través del autoconcepto emocional y académico, el desajuste psicológico (hostilidad/agresión, autoestima negativa, irresponsividad emocional, inestabilidad emocional y visión negativa del mundo) y el rendimiento académico (nota media y número de cursos repetidos). Se comprobaron los efectos principales y de interacción de estilo parental y autoeficacia. Los resultados de los efectos principales indicaron que los adolescentes con baja autoeficacia presentaban siempre la peor competencia psicosocial. También que los adolescentes de familias indulgentes y autorizativas presentaron mejores resultados que los de familias negligentes y autoritarias. Sin embargo, el estilo parental indulgente se asoció a los mejores resultados. El impacto de la socialización parental podría no ser igual en todos los contextos culturales. Frente a los resultados de los estudios clásicos, la severidad parental parece ser innecesaria o incluso perjudicial para los adolescentes con baja y alta autoeficacia.(AU)

The aim of this paper is to establish which parenting style is as-sociated with optimum outcomes among adolescents of Spanish families considering adolescents with low vs. high self-efficacy. Although classical studies identify the authoritative parenting style (based on warmth and strictness) as the best parental strategy, emerging research seriously ques-tions the benefits of parental strictness. Additionally, the impact of parent-ing on the adolescent’s psychosocial competence has been studied for years, but less is known about whether it might vary depending on individ-ual characteristics of the adolescent (e.g., self-efficacy). Participants were 1029 Spanish adolescents, 453 males (44%), aged 12-17 years. Families were classified in one of the parenting styles groups (authoritative, authori-tarian, indulgent, or neglectful), and adolescents were grouped by low vs. high self-efficacy. Adolescent psychosocial competence was examined through emotional and academic self-concept, psychological maladjust-ment (hostility/aggression, negative self-esteem, emotional responsivity, instability, and negative view of the world), and academic performance (grade point average and number of failing grades). Main and interaction effects of parenting style and adolescent self-efficacy were tested. Main ef-fect results indicated that adolescents with low self-efficacy were always as-sociated with the worst psychosocial competence. Consistently, the main effect findings indicated that adolescents from indulgent and authoritative families were associated with better results than those from neglectful and authoritarian families. However, the indulgent parenting style yielded the best results. The impact of parenting might not be the same for adoles-cents in all cultural contexts. Contrary to findings from classical studies, parental strictness seems to be unnecessary or even detrimental for adoles-cents with low and high self-efficacy.(AU)

Maternal high body mass index, but not gestational diabetes, is associated with poorer educational attainment in mid-childhood.

BACKGROUND: Previous studies suggest that gestational diabetes mellitus is associated with poorer cognitive outcomes in children. However, confounding factors, especially maternal body mass index, have been poorly accounted for. OBJECTIVE: This study aimed to examine the independent associations between maternal body mass index, gestational diabetes mellitus status, and educational outcomes. STUDY DESIGN: Antenatal data from a prospective birth cohort (Pregnancy Outcome Prediction Study, 2008-2012, Cambridge, United Kingdom) were linked to mid-childhood educational outcomes (Department for Education, United Kingdom). A total of 3249 children born at term were stratified by maternal gestational diabetes mellitus status and body mass index at booking (<25 vs ≥25 kg/m2). Regression models adjusted for relevant maternal, child, and socioeconomic factors were used to determine associations with academic outcomes at ages of 5 to 7 years. RESULTS: No differences in educational attainment were found between children exposed to gestational diabetes mellitus and nonexposed children. Neither maternal glucose levels measured at 11 to 14 or 24 to 28 weeks, nor acceleration of the fetal abdominal circumference growth velocity were related to educational attainment at ages of 5 to 7 years. Children of mothers with booking body mass index ≥25 kg/m2 (vs <25 kg/m2) were ∼50% more likely to not meet expected educational standards regardless of gestational diabetes mellitus status (age 5: adjusted odds ratio, 1.44; 95% confidence interval, 1.19-1.74; P<.001; age 6: adjusted odds ratio, 1.61; 95% confidence interval, 1.28-2.02; P<.001). The association between maternal body mass index and offspring educational attainment is dose-dependent and robust to stratification by gestational diabetes mellitus status and adjustment for socioeconomic factors. CONCLUSION: Mid-childhood educational attainment is not associated with maternal glucose status. This may provide important reassurance for pregnant women and clinicians. However, maternal body mass index is associated with lower childhood educational attainment and may be modifiable with intervention before or during pregnancy.

Factors Contributing to School Effectiveness: A Systematic Literature Review.

This paper aims to provide a systematic review of the literature on school effectiveness, with a focus on identifying the main factors that contribute to successful educational outcomes. The research question that this paper aimed to address is "what are the main factors of school effectiveness?". We were interested in several descriptors such as school, effectiveness/efficiency theories, effectiveness/efficiency research and factors. Studies (published within the 2016-2022 period) were retrieved through two databases: JSTOR and ERIC. This paper defines several categories identified by school effectiveness research. Within these categories, various factors that affect the students' outcomes and the defined effectiveness in school are listed. As the results show, the issue of school effectiveness is multifaceted, as the effectiveness of schools is a complex concept that can be measured through various indicators such as academic achievement, student engagement and teacher satisfaction. The review of school effectiveness revealed that several factors contribute to effective schools, such as strong leadership, effective teaching practices, a positive school culture and parental involvement. Additionally, school resources, such as funding and facilities, can impact school effectiveness, particularly in under-resourced communities.

Post-COVID Neuropsychiatric Complications in Children and Adolescents: a Study Design for Early Diagnosis and Treatment Using Innovative Technologies.

BACKGROUND: The COVID-19 pandemic has had significant impacts on the child and adolescent population, with long-term consequences for physical health, socio-psychological well-being, and cognitive development, which require further investigation. We herein describe a study design protocol for recognizing neuropsychiatric complications associated with pediatric COVID-19, and for developing effective prevention and treatment strategies grounded on the evidence-based findings. METHODS: The study includes two cohorts, each with 163 participants, aged from 7 to 18 years old, and matched by gender. One cohort consisted of individuals with a history of COVID-19, while the other group presents those without such a history. We undertake comprehensive assessments, including neuropsychiatric evaluations, blood tests, and validated questionnaires completed by parents/guardians and by the children themselves. The data analysis is based on machine learning techniques to develop predictive models for COVID-19-associated neuropsychiatric complications in children and adolescents. RESULTS: The first model is focused on a binary classification to distinguish participants with and without a history of COVID-19. The second model clusters significant indicators of clinical dynamics during the follow-up observation period, including the persistence of COVID-19 related somatic and neuropsychiatric symptoms over time. The third model manages the predictors of discrete trajectories in the dynamics of post-COVID-19 states, tailored for personalized prediction modeling of affective, behavioral, cognitive, disturbances (academic/school performance), and somatic symptoms of the long COVID. CONCLUSIONS: The current protocol outlines a comprehensive study design aiming to bring a better understanding of COVID-19-associated neuropsychiatric complications in a population of children and adolescents, and to create a mobile phone-based applications for the diagnosis and treatment of affective, cognitive, and behavioral conditions. The study will inform about the improved management of preventive and personalized care strategies for pediatric COVID-19 patients. Study results support the development of engaging and age-appropriate mobile technologies addressing the needs of this vulnerable population group.

Aphantasia within the framework of neurodivergence: Some preliminary data and the curse of the confidence gap.

Aphantasia is a neurocognitive phenomenon affecting voluntary visual imagery, such that it is either entirely absent, or markedly impaired. Using both the social and medical models of disability, this article discusses the extent to which aphantasia can be understood as a disorder or just a form of neutral neurodivergence, given that imagery plays a central role in thinking and memory for most other people. Preliminary school performance data are presented, showing that low imagery does not necessarily complicate life, especially given compensatory strategies and low societal barriers. In addition, we discuss the consequences of labelling aphantasia a disorder with regard to self- and public stigma, and we provide further data regarding a confidence gap, by which aphantasics perceive themselves as performing worse than they objectively do. We conclude that aphantasia should be understood as neutral neurodivergence and that labelling it a disorder is not only wrong, but potentially harmful.

Self-control and grit are associated with school performance mainly because of shared genetic effects.

Background: By combining the classical twin design with regression analysis, we investigated the role of two non-cognitive factors, self-control and grit, in the prediction of school performance. We did so at the phenotypic, genetic, and environmental level. Methods: Teachers filled out a survey on the twins' school performance (school grades for reading, literacy, and math), self-control (ASEBA self-control scale), and grit (the perseverance aspect) for 4891 Dutch 12-years-old twin pairs (3837 pairs with data for both and 1054 pairs with data for one of the twins). We employed regression analyses to first assess the contributions of self-control and grit to school performance at the phenotypic level, and next at the genetic and environmental level, while correcting for rater (teacher) effects, parental SES, and sex. Results: Higher SES was associated with better school performance, self-control, and grit. On average, girls had more self-control and grit than boys. Corrected for sex, SES, and teacher rater effects, genetic factors accounted for 74%, 69%, and 58% of the phenotypic variance of school performance, self-control, and grit, respectively. Phenotypically, self-control and grit explained 28.3% of the variance in school performance. We found that this phenotypic result largely reflected genetic influences. Conclusions: Children who have better self-control and are grittier tend to do better in school. Individual differences in these three traits are not correlated because of shared environmental influences, but mainly because of shared genetic factors.

Associations of adolescents' diet and meal patterns with school performance in the Northern Finland Birth Cohort 1986: A Mendelian randomisation study.

BACKGROUND: Several observational studies indicate that dietary habits in children and adolescents are associated with school performance. These associations are heavily confounded by socio-economic characteristics, such as household income and parents' educational attainment, amongst other factors. The objective of this study was to explore the association between diet and school performance in adolescents from the Northern Finland Birth Cohort 1986 (NFBC1986). METHODS: Dietary and school performance data were collected using self-reported questionnaires from adolescents in the NFBC1986 cross-sectional, 16-year follow-up study. In this work we derived exploratory factors for the dietary variables, frequency of skipping main meals and school performance variables, performed genome-wide association studies (GWAS) against these factors to obtain genetic association data and conducted one-sample and two-sample Mendelian randomisation (MR) analyses using individual level data for up to 9220 adolescents in NFBC1986 and GWAS results from external cohorts. We report observational and MR effects of diet on school performance and cognition-related phenotypes. RESULTS: The observational study and the one-sample Mendelian randomisation analysis showed that high fat, salt and sugar (HFSS) consumption was associated with poor school performance in general/science subjects (-0.080, -0.128 to -0.033) and staple food consumption with better school performance in general/science subjects (0.071, 0.024 to 0.119) and physical education (0.065, 0.021 to 0.110). Findings from our two-sample MR analysis identified dietary principal components described best as whole brain bread, wheat, cheese, oat cereal and red wine to be associated with higher educational attainment and other cognition-related phenotypes. CONCLUSION: Using genetics, we highlighted the potential role of HFSS food consumption and consumption of the components of a staple food diet for school performance. However, further research is required to find conclusive evidence that could support a causal role of diet on school performance.
