Rethinking the Exploration of Dichotomous Data
The need to determine the correct dimensionality of theoretical constructs and generate valid measurement instruments when underlying items are categorical has generated a significant volume of research in the social sciences. This article presents two studies contrasting different categorical exploratory techniques. The first study compares Mokken scale analysis (MSA) and two-factor-based exploratory techniques for noncontinuous variables: item …
Cómo investigan las ciencias sociales temas de alta contingencia política. El caso del movimiento estudiantil chileno
El presente trabajo investiga la forma en que las ciencias sociales, principalmente chilenas, están respondiendo a las dispares demandas que reciben actualmente y que consisten en aportar a la comprensiÃ3n crítica de fenÃ3menos relevantes para la sociedad y adecuarse a las recientes transformaciones en la forma de producir y comunicar conocimiento científico incorporando mayores niveles de internacionalizaciÃ3n, globalizaciÃ3n, especializaciÃ3n y…
The sirens’ call in psychometrics
The idea that item response theory (IRT) models yield invariant parameter estimates is widely accepted among scholars interested in achieving truly scientific measurements in social and behavioral sciences. Starting from a conceptual and mathematical definition of invariance, this article presents a critical examination of the theoretical and empirical support for the property of invariance with regard to populations and samples of items and subj…
Evaluación docente universitaria
La calidad de la docencia universitaria se evalúa principalmente a través de cuestionarios aplicados a los estudiantes, los que no siempre surgen de un enfoque teórico sólido. Con el fin de avanzar en la construcción de un modelo teórico que dé sustento a al desarrollo de instrumentos de evaluación, tres fuentes de demandas hacia la docencia universitaria: demandas de los estudiantes, demandas del modelo de formación por competencias y demandas d…
Developing Multidimensional Likert Scales Using Item Factor Analysis
This study compares the performance of two approaches in analysing four-point Likert rating scales with a factorial model: the classical factor analysis (FA) and the item factor analysis (IFA). For FA, maximum likelihood and weighted least squares estimations using Pearson correlation matrices among items are compared. For IFA, diagonally weighted least squares and unweighted least squares estimations using items polychoric correlation matrices a…
