RESUMEN

This research presents the findings of a comparative study of mathematical competence among 130 students (M = 54.08 months; SD = 2.57) from vulnerable school contexts in Chile and the Spanish public school system. The study analyses a set of general and specific domain precursors for which evidence of socioeconomic background exists. Using multivariate regression and discriminant analysis techniques, we calculated similarities and differences between groups by comparing these precursors. Significant differences were found between the Spanish and Chilean groups (p < .05); however, no differences were observed in non-symbolic comparison and receptive vocabulary. Possible reasons for the existence and extent of these differences are discussed in terms of socio-cultural and educational contexts.

RESUMEN

BACKGROUND: Evidence suggests that children from low-income families begin the preschool stage with less academic and non-academic skills development compared to higher-income families. There are several successful experiences of early stimulation of cognitive and social-emotional skills; however, there is scarce evidence of the effectiveness of a video game that incorporates the stimulation of these skills simultaneously. This study aims to evaluate the effectiveness of a video game in stimulating cognitive, emotional, and social competence skills in developing academic skills in socioeconomically disadvantaged preschool children. METHODS: A cluster-randomized controlled trial design will be used. A tablet-based video game that stimulates cognitive and socio-emotional skills to improve the development of academic skills is compared with a tablet-based game where students draw and paint with no explicit stimulation of cognitive and socio-emotional skills. Eighteen schools and 750 Chilean preschool students will be recruited. The effectiveness of the intervention will be assessed using a direct evaluation of children on literacy learning and pre-calculation skills at baseline, immediately after stimulation, and at 6, 12, 18, and 24 months post-intervention. The mediating effect of working memory, inhibitory control, emotion recognition, and prosocial behaviours will be assessed on the effectiveness of the intervention. DISCUSSION: The proposed study will be the first to test the effectiveness of a tablet-based video game stimulating cognitive and social-emotional skills to improve academic skills in socioeconomically disadvantaged preschool children in Chile, controlling for gender, age (in months), mental health, and baseline conditions of stimulated skills. TRIAL REGISTRATION: ClinicalTrials.gov NCT05224700. Registered on February 2022.

RESUMEN

The d2, test of attention is one of the most used neuropsychological tests to measure attention in clinical and research settings. To date, no studies have examined neither its convergent and divergent validity in children nor its relationship with academic skills at school age. The aims of the present study were: (1) to examine the convergent and divergent validity of the d2 Test in a non-clinical pediatric population, (2) to explore the relationship between d2 task performance and academic skills (i.e., math, reading and writing abilities) and (3) to develop normative data for Spanish-speaking children (n = 360 8- to 12-year-old children) stratified by age and socioeconomic status (SES). Pearson's correlation and Structural Equation Models (SEM) were used to analyze the d2 Test validity and its relationship with academic skills. A between-subjects factorial MANOVA was used to examine differences among SES (Middle, Low), age (8-10, 11-12), and sex (male, female). Findings revealed a significant relationship between d2 task performance and all attention and executive functions (EF) measures under analysis providing evidence of good convergent validity. Furthermore, SEM results showed that attention has direct effects on math and reading and writing skills. Finally, our study confirms the influence of age and SES on d2 task performance and provides normative data for middle- and low-SES children. These results have important implications for the assessment of attention functions in clinical and research settings in children with typical and atypical development.

RESUMEN

El objetivo del presente estudio fue indagar acerca del efecto del uso de estrategias cognitivas de regulación emocional sobre las habilidades académicas de cálculo y comprensión lectora en población adolescente. Para ello, se administró el Cuestionario de Regulación Emocional Cognitiva, la Prueba de Competencia Lectora para Educación Secundaria y el sub-test de aritmética de la Prueba de Logro de Amplio Rango, a 65 participantes (género: F: 40, M: 25; ME = 15.52, DE = .69) de una escuela concertada de la ciudad de Valladolid, España. Los resultados indican que el uso de estrategias desadaptativas ­y no así el uso de estrategias adaptativas­ explica el rendimiento en las pruebas de habilidades académicas. Los resultados se discuten en relación a la literatura, señalando los efectos negativos sobre el aprendizaje del uso de estrategias desadaptativas como Rumiación, Catastrofización y Autoculparse

The aim of the present study was to analyze the effect of the use of cognitive emotion regulation strategies on the academic skills (calculation and reading comprehension) of adolescent population. To this end, the Cognitive Emotion Regulation Questionnaire, the Reading Competency Test for Secondary Education and the arithmetic subtest of the Wide Range Achievement Test, were administered to 65 participants (gender: F: 40, M: 22; age: ME = 15.52, DE = .69). Students belonged to a concerted school from the city of Valladolid, Spain. The results indicate that the use of maladaptive strategies -and not the use of adaptive strategies- explains the performance on academic skills tests. The results are discussed in relation to the literature, highlighting the negative effects of the use of maladaptive strategies such as Rumination, Catastrophizing and Self-blaming, on learning

RESUMEN

Abstract School deficit is considered a risk factor for the development of antisocial behavior. This study assessed the efficacy of individual program on academic skills for adolescents admitted to juvenile detention. The sample consisted of 18 adolescents, nine who received the intervention (experimental group) and nine in the control group. The schooling activities were developed in a range of 12 to 18 weeks with two to four hours per week and efficacy was measured by School Performance Test (SPT) that evaluates writing, reading and arithmetics. The results of the comparison between pretest and post-test showed a statistically significant increase in the experimental group's math skills (Z = -2.673, p = .008) and overall score (Z = -2.549, p = .012). Calculated via the STP the average educational lag at the time of the pretest was 8.3 years for the experimental group and 8.9 years for the control group. Subsequent to the intervention, the average lag dropped to 7.3 years for the experimental group and remained to 8.6 years for the control group. This intervention proved to be a promising technique to reduce academic deficits in adolescents from juvenile detention.

Resumo O déficit escolar é considerado um fator de risco para o desenvolvimento do comportamento antissocial. Esse estudo avaliou a eficácia de um programa para o desenvolvimento de habilidades acadêmicas para adolescentes em conflito com a lei. A amostra foi composta por 18 adolescentes, nove receberam a intervenção (grupo experimental) e nove participaram do grupo controle. As atividades de estimulação foram desenvolvidas entre duas e quatro horas semanais em um período entre 12 e 18 semanas. A eficácia do programa foi medida pelo Teste de Desenvolvimento Escolar (TDE) que avalia habilidades de escrita, leitura e aritmética. Os resultados da comparação entre pré teste e pós teste demonstraram que o grupo experimental teve melhoras significativas nas habilidades aritméticas (Z = -2,673, p = 0,008) e no escore total (Z = -2,549, p = 0,012). Medida pelo TDE a média de atraso escolar no pré teste foi de 8,3 anos no grupo experimental e de 8,9 anos no grupo controle. Após a intervenção a média caiu para 7,3 anos no grupo experimental e se manteve em 8,6 anos no grupo controle. Essa intervenção demonstrou ser uma técnica promissora para reduzir déficits escolares em adolescentes em conflito com a lei.

Resumen El déficit escolar se considera un factor de riesgo para el desarrollo del comportamiento antisocial. Esta investigación evaluó un programa de escolarización individual, en la modalidad refuerzo escolar, con adolescentes internados en unidad de socio educación. La muestra se constituyó de 18 adolescentes, nueve que recibieron la intervención y nueve en grupo control. Las actividades de escolarización se desarrollaron en un intervalo de 12 a 18 semanas, con duración de dos a cuatro horas por semana. Sus efectos fueron medidos por el Teste de Desarrollo Escolar (STP) que evaluó lectura, escritura y aritmética. Los resultados de la comparación del pre con el pos test demostraron que hubo aumento significativo de aprendizaje en aritmética (Z = -2.673, p <0,008) y en la puntuación total (Z = -2,549, p <0,012) en el grupo objetivo. El promedio del desfase escolar en pre-test, calculado por el STP, fue de 8,3 años para el grupo objetivo y 8,9 años para el control; después de la intervención promedio el desfasaje escolar cayó a 7,3 años para el grupo objetivo y se mantuvo en 8,6 para el control. La intervención en la escolarización se mostró prometedora para reducir el déficit escolar de adolescentes en régimen de internación.

RESUMEN

Resumen Las habilidades académicas constituyen un componente específico del éxito escolar y numerosos factores influyen en su adquisición y consolidación. Uno de estos es la habilidad de regulación emocional de tolerancia al distrés, que se define por la capacidad de resistir esta dos emocionales negativos en pos de un objetivo. El propósito de este trabajo fue analizar la relación entre la tolerancia al distrés y las habilidades académicas de comprensión lectora y cálculo matemático en 107 niños de escolaridad primaria de 9 a 11 años de edad. Los resultados mostraron que la tolerancia al distrés resultó un predictor significativo de la comprensión lectora de textos expositivos y del cálculo matemático, no así de la comprensión lectora de textos narrativos. Es posible que la tolerancia al distrés resulte un factor relevante para el éxito académico en varios dominios.

Abstract Academic skills are a specific component of academic success, and many factors influence their acquisition and consolidation. One of these factors is the ability to emotionally regu late distress tolerance, as defined by the ability to withstand negative emotional states in pursuit of a goal. This paper undertook to analyse the relationship between distress tole rance and reading comprehension and mathematical computations in 107 primary school children aged 9 to 11. The results showed that distress tolerance was a significant predictor of reading comprehension of expository texts and mathematical computations, albeit not so for reading comprehension of narrative texts. Distress tolerance is likely to be a relevant factor for academic success in several domains.

RESUMEN

En este artículo se trabajó con una muestra de niños y niñas escolarizados de entre 6 y 14 años con diagnóstico de TDAH, de la ciudad de Manizales (Colombia), durante 2011. Se buscó correlacionar el desempeño neuropsicológico con las tareas de habilidades académicas de lectura y escritura, cruzando las variables correspondientes a las habilidades académicas de lectura y escritura contra el proceso de atención, el proceso de memoria y el desempeño en funciones ejecutivas. Se confirmó el valor predictivo que tiene el desempeño de los niños y niñas en la evaluación de algunas variables neuropsicológicas, en sus posibilidades de funcionamiento escolar y en su nivel de apropiación y desempeño académico.

This article is the product of a research developed with a sample of school children between 6 and 14 years diagnosed with ADHD, in the city of Manizales (Colombia) during 2011. We aimed at correlatingthe neuropsychological performance to the tasks of academic reading and writing across the variables corresponding to the academic skills of reading and writing against the care process, the process of memory and performance on executive functions. We confirmed the predictive value of children performance in the assessment of neuropsychological variables, their chances of functioning in school and in their level of appropriation and academic performance.
