A comparison of the graded response and partial credit models with a scale of usefulness of mathematics

The Graded Response Model (GRM) and the Partial Credit Model (PCM) of Item Response Theory (IRT) were applied in the item analysis of a scale that evaluates psychology students's beliefs about the usefulness of mathematics. The scale comprises 8 items in polytomous response format (6-point Like...

The scale comprises 8 items in polytomous response format (6-point Likert-type). The sample was made up by 1875 students of the Psychology school of the University of Buenos Aires. All analyses based on IRT were performed by operating the MULTILOG software. The parameters estimation was carried out trough Marginal Maximum Likelihood procedures. Previously, the unidimensionality assumption required by the models was confirmed. The GRM showed better fit indexes than PCM and higher Test Information Function. The findings provides validity evidences based on the internal structure of scale. Se aplicaron los Modelos Respuesta Graduada (MRG) y Crédito Parcial (MCP) de la Teoría de Respuesta al Ítem (TRI) al análisis de ítems de una escala que mide las creencias sobre la utilidad de la Matemática de estudiantes de Psicología. La prueba consta de 8 ítems con formato de respuesta Likert de 6 opciones. Participaron 1875 estudiantes de Psicología de la Universidad de Buenos Aires. Todos los análisis basados sobre la TRI se realizaron con el programa MULTILOG. La estimación de los parámetros de los modelos se efectuó por Máxima Verosimilitud Marginal. Previamente se verificó la condición de unidimensionalidad requerida por los modelos. El MRG presentó mejores indicadores de ajuste que el MCP y una Función de Información del Test más elevada. Se hallaron asociaciones entre los escalamientos realizados desde la TRI y la teoría clásica. Los resultados aportan evidencias de validez basadas en la estructura interna del instrumento.
