Procesos metacognitivos: implicaciones en las dificultades de aprendizaje de las matemáticas El concepto de metacognición fue definido por Flavell [8] como el conocimiento acerca de los propios procesos o productos NEW TRENDS IN THE EVALUATION OF MATHEMATICS LEARNING DISABILITIES. THE ROLE OF METACOGNITION Summary. Introduction. The current trends in the evaluation of mathematics learning disabilities (MLD), based on cognitive and empirical models, are oriented towards combining procedures involving the criteria and the evaluation of cognitive and metacognitive processes, associated to performance in mathematical tasks. Aims. The objective of this study is to analyse the metacognitive skills of prediction and evaluation in performing maths tasks and to compare metacognitive performance among pupils with MLD and younger pupils without MLD, who have the same level of mathematical performance. Likewise, we analyse these pupils' desire to learn. Subjects and methods. We compare a total of 44 pupils from the second cycle of primary education (8-10 years old) with and without mathematics learning disabilities. Results. Significant differences are observed between pupils with and without mathematics learning disabilities in their capacity to predict and assess all of the tasks evaluated. As regards their 'desire to learn', no significant differences were found between pupils with and without MLD, which indicated that those with MLD assess their chances of successfully performing maths tasks in the same way as those without MLD. Finally, the findings reveal a similar metacognitive profile in pupils with MLD and the younger pupils with no mathematics learning disabilities. Conclusions. In future studies we consider it important to analyse the influence of the socioaffective belief system in the use of metacognitive skills.
