Learning the functional significance of mnemonic actions: A microgenetic study of strategy acquisition

Abstract

How children learn to use memory strategies in a microgenetic investigation of learning and metacognition is examined. Seven- and eight-year-olds were given two memory trials with 24 pictures on each of 5 consecutive days. Days 1 and 2 were baseline, practice trials; Day 3 included strategy training; and Days 4 and 5 were unprompted tests of strategy maintenance. All children were taught how to label, rehearse, and group the pictures as well as to self-test their own memories and use blocked recall. Half of the children were shown the actions and told to do them; the other half received elaborated feedback on the usefulness and appropriateness of the techniques for remembering. The elaborated instructional group exhibited significantly greater recall, clustering, strategic study behavior, and metamemory regarding the mnemonic techniques than the other group. Path analysis provided evidence of a causal role of training and metacognitive awareness that mediated the use of sorting and higher recall. The study illustrates how learning the significance and utility of mnemonic techniques can influence children's acquisition of the tactics as self-controlled strategies. In addition, the microgenetic method affords patterns of data across time and experience that permit richer interpretations of strategy learning and memory development.
