A structural model of cognitive-motivational variables as explanatory factors of academic achievement in Spanish Language and Mathematics

In recent years, several explanatory models have been developed which attempt to analyse the predictive worth of various factors in relation to academic achievement, as well as the direct and indirect effects that they produce. The aim of this study was to examine a structural model incorporating various cognitive and motivational variables which influence student achievement in the two basic core skills in the Spanish curriculum: Spanish Language and Mathematics. These variables included differential aptitudes, specific self-concept, goal orientations, effort and learning strategies. The sample comprised 341 Spanish students in their first year of Compulsory Secondary Education. Various tests and questionnaires were used to assess each student, and Structural Equation Modelling (SEM) was employed to study the relationships in the initial model. The proposed model obtained a satisfactory fit for the two subjects studied, and all the relationships hypothesised were significant. The variable with the most explanatory power regarding academic achievement was mathematical and verbal aptitude. Also notable was the direct influence of specific self-concept on achievement, goal-orientation and effort, as was the mediatory effect that effort and learning strategies had between academic goals and final achievement.

Relación del gasto en ocio y vacaciones con variables del ciclo de vida del hogar, demográficas, geográficas y económicas

El gasto en ocio y vacaciones de los hogares puede depender de variables demográficas, geográficas y económicas asociadas al hogar o al sustentador principal. También afecta el tipo de hogar, cuya clasificación puede realizarse según los modelos considerados en la teoría del ciclo de vida del hogar (CVH). En este trabajo, se utiliza el programa estadístico SPAD para aplicar la metodología de la caracterización de la variable y analizar el poder explicativo de un total de doce variables sobre el gasto en “vacaciones todo incluido”, “servicios culturales” y otras cinco partidas destacadas del grupo “Ocio, espectáculos y cultura” de la Encuesta de Presupuestos Familiares (EPF) de España. El estudio confirma el interés de considerar variables como el número de dependientes para segmentar consumidores de ocio y vacaciones, pero no de variables más complejas basadas en modelos del CVH.
