Análisis de los componentes en la adquisición de la lectura en castellano: Una aplicación del modelo logístico lineal

The basic components for the acquisition of reading in Spanish are analyzed by using the Fisher Linear Logistic Test Model (LLTM). An extensive battery designed to assess different Basic Processes for Reading (PROBALES, acronym in Spanish) was applied to 245 children aged 4 to 9. Factor analysis techniques were used to select a subset of items that would adjust to the Rasch model. The LLTM confirmed the validity of the theoretical model which states that reading acquisition relies on the development of three basic skills: word recognition, phonological awareness, and reading comprehension. The theoretical model's predictive ability is shown by discriminant analysis, thereby confirming that 68% of participants were correctly classified in their school grade.
