Progression paths in children's problem solving:The influence of dynamic testing, initial variability and working-memory AbstractThe current study investigated developmental trajectories of analogical reasoning performance of 104 7-to-8-year-old children. We employed a microgenetic research method and multilevel analysis to examine the influence of several background variables and experimental treatment on the children's developmental trajectories. Our participants were divided into two treatment groups: repeated practice alone and repeated practice with training. Each child received an initial working-memory assessment, and was subsequently asked to solve figural analogies on each of several sessions. We examined children's analogical problem-solving behavior and their subsequent verbal accounts of their employed solving processes. We also investigated the influence of verbal and visual-spatial working-memory capacity and initial variability in strategyuse on analogical reasoning development. Results indicated that children in both treatment groups improved but gains were greater for those who had received training. Training also reduced the influence of children's initial variability in the use of analogical strategies with the degree of improvement in reasoning largely unrelated to working memory capacity. Findings from this study demonstrate the value of a microgenetic research method and the use of multilevel analysis to examine inter-and intra-individual change in problem-solving processes.

Abstract (150 words max)This study examined the problem-solving behaviour of 104 children (aged 7-8 years) when tackling construction-analogy tasks. Children were allocated to one of two conditions: either a form of unguided practice alone or this in combination with training based on graduated prompt techniques.Children's ability to solve figural open-ended analogy-problems was investigated as well as their ability to construct new analogy problems themselves. We examined children's progression in solving analogy problems and the variability in their strategy-use. Results showed that the group that received training made greater progress in solving analogy problems than children who only received unguided practice opportunities. However, the training appeared to give no additional improvement in performance on the transfer task over that of repeated unguided practice alone. Findings from this study demonstrate that an open construction task can provide additional information about children's cognitive learning potential.
