    Prediction of academic achievement in Dominican students: Meditational role of learning strategies and study habits and attitudes toward study
    (2022-07-18) Betty Reyes
    School or academic achievement is a relevant topic of study, as it is evidence of the learning achieved by the student. This study aims to explore a model explaining academic achievement while testing the mediator role of learning strategies, study habits and study attitudes. Research design was correlational. 1712 Dominican students from 12 to 20 years old (52.75% female) were sampled through cluster sampling. Data was recruited with a set of validated questionnaires, including measures of academic achievement (marks), learning strategies, study habits, and attitudes toward studies, school engagement, and academic support. Structural Equation Modeling was used to establish and test the mediational model. Main results show that learning strategies and study habits and attitudes play a mediator role between background variables as age, gender, cognitive or behavioral engagement, and students’ academic achievement. Learning strategies and study habits play a central role in achieving a good academic performance, by mediating the effects of academic support and school engagement.

    Entre el creciente cuerpo de investigación que se ha centrado en el éxito académico, la motivación académica ha captado considerable atención. El objetivo de esta investigación es presentar la primera validación de la Escala de Motivación Académica de los Adolescentes (EMAA). La muestra total estuvo compuesta por 1712 estudiantes de secundaria de dos distritos de la República Dominicana. La medida principal fue la EMAA. Los resultados del AFC fueron satisfactorios: χ2(5) = 57.73, p < .001; CFI = .970; RMSEA = .079, 90% CI [.061, .097], y SRMR = .024. Los análisis de TRI favorecieron al modelo logístico de dos parámetros, indicando que los ítems no fueron igualmente discriminativos. El Modelo de Ecuaciones Estructurales en el que la motivación académica predecía de forma estadísticamente significativa las calificaciones obtuvo un ajuste excelente: χ2(53) = 182.76, p < .001; CFI = .980; RMSEA = .038 [.032, .044], and SRMR = .025. En resumen, este trabajo presenta un exhaustivo análisis psicométrico de la EMAA en una muestra representativa de estudiantes dominicanos de instituto.
