Psychometric properties of an experimental test for the assessment of basic arithmetic calculation efficiency / Propiedades psicométricas de una prueba experimental para la evaluación de la eficacia del cálculo aritmético básico
In this article the ‘Arithmetic Calculation Efficiency Test’ (Test de Eficacia en el cálculo aritmético – TECA), a test for the assessment of arithmetic efficiency in terms of precision and speed in school-aged subjects, is introduced. The test aims to contribute to educational practices and the diagnosis of students who are at risk of Learning Difficulties in Calculations (LDC). Psychometric properties of the test items were analysed based on a sample of 331 subjects from grade 1 to 6 from Primary School. Analysis of content validity, item analysis, dimensionality and reliability have provided evidence of the validity of a one-dimensional structure consistent with the theoretical framework.
