Las actitudes hacia las matemáticas: construcción y validación de un instrumento para su medida

The measure of attitudes towards mathematics is a valuable area within the so-called affective domain in mathematics due to the number of investigations and the extension of their relations. However, most of the instruments currently available to measure these attitudes are validated by not overly robust psychometric procedures and, sometimes, in not very large samples. Using a sample of 4807 students of all the non-university levels and following both the classical test theory, structural equation models (measurement models), and the proposal of the item response theory (graded response model), a solid and robust instrument to measure attitudes towards mathematics is presented, with contrasted evidence of validity and reliability.
