Instrumento de detección de alumnos con dificultades en el aprendizaje de las matemáticas : análisis de consistencia interna y validez de constructo

In the context of the neuropsychology, whose maximum represente is Luria, we are going to approach a top function, the calculation. From the cognitive neuropsychology, the emphasis has been put in defining a system of processing the information. The model which is developed by McCloskey and this collaborators is, perhaps, the most influence. The first author of this paper has developed this model so as a collective instrument in order to assessment the mathematical learning disabilities and, subsequent, develop a individualized assessment of those case which show mathematical learning disabilities. In order to know the power of this instrument, we have analized its psychometric properties: internal consistency and construct validity. The result of this research shows us the acceptability of reliability and confirms the existence of two factors which explains the factorial structure of this instrument.
