Much interest has been expressed in the construct metacognition, the individual's knowledge and control of his own cognitive processes. Recent educational proposals have suggested the training of general metacognitive principles in schools. The exact nature of the construct has, however, remained vague. The aim of the present study was to provide some clarity. In a study of the metacognitive responses of 144 primary school children (aged 7-11 years) four measures commonly used to assess metacognitive function were examined. First, the content of each measure was examined. Secondly, in an attempt to identify a metacognitive factor, commonality among the measures, both of developmental patterns and statistical relationship, was sought. Whilst a common pattern of development in the children's responses to the four measures was identified, factor analysis failed to provide evidence for a common metacognitive factor and unified construct.In the last 15 years much interest has centred on the concept of metacognition: the individual's knowledge of cognition and regulation of his own cognitive processes. Metacognition has been the focus of research, particularly for developmentalist and, more recently, for its educational relevance (Feuerstein et al, 1980; Nisbett & Shucksmith, 1986;Sternberg, 1989). It has been suggested that identification of children's knowledge of their own memory functioning and its limitations might form the basis for teaching. Children's learning might be enhanced by training in broad metacognition skills and strategies whilst teachers might harmonise their teaching with the strengths and limitations of their pupils. Despite the interest accorded metacognition and a number of research reviews which have called for greater clarity, however 5 Downloaded by [Computing & Library Services, University of Huddersfield] at 23:36 26 December 2014 6 K. J. Thorpe & D. J. H. Satterly( Brown et al., 1983;Wellman, 1983;Schneider, 1985), metacognition remains "a fuzzy concept" (Wellman, 1983).The range of tasks in which metacognitive differences have been observed is diverse. The present paper seeks to provide some clarity. Its aim is to identify the essence of the concept as it is used in the literature by examining the measures commonly used to access it. First, it examines the nature of individual measures of metacognition. Secondly, it examines the relationship between measures in an endeavour to identify those points of commonality which might be identified as metacognitive factor.
Measures of MetacognitionCurrent measures of metacognition are largely derived from studies whose aim is to describe its development. These studies have typically observed, cross-sectionally, children's responses to specific individual cognitive tasks (learning, problem-solving) from which a metacognitive component is derived. This metacognitive component is not so much the outcome of the task (how much is learned or the solution of the problem) but rather the principles applied (metacognitive knowledge) and the conscious contr...
