The Effects of Self- and Other-Scaffolding on Progression and Variation in Children’s Geometric Analogy Performance: A Microgenetic Research

The study investigated geometric analogical reasoning in 8-year-old children by microgenetically examining the (transfer) effects of self- and other-scaffolding and memory capacity on progression and variation in children’s analogy performance. Participants were 54 children, divided over three conditions, and followed for 5 weeks. Children’s initial performances showed a wide strategy repertoire. A number of children profited from repeated self-scaffolding and increased their strategy use considerably. A 20-minute graduated-prompts other-scaffolding procedure promoted strategy use beyond the effects of self-scaffolding, inducing either continuation of gradual change or a rapid change in analogical reasoning. Distinct change trajectories showed individual differences regarding timing and rate of change. There was evidence of transfer of analogy strategies between geometric and verbal tasks. Children with a larger memory capacity remained at higher levels of geometric analogical reasoning. Children with smaller memory capacities fully caught up with their peers with a larger memory capacity after other-scaffolding.
