Research suggests that parents are effective at scaffolding their children's learning to help them become self-regulated problem solvers. Yet little is known about parents' effectiveness at assisting their children with problems that parents find unfamiliar and, thus, do not have at hand either the solution or strategies that a novice child could profitably implement. In this study, 20 dyads of parents and their preadolescent children spent 45 min solving a scientific reasoning problem that entailed generating and interpreting a series of experimental trials to understand the causal structure
Children often learn new problem-solving strategies by observing examples of other people's problem-solving. When children learn a new strategy through observation and also explain the new strategy to themselves, they generalize the strategy more widely than children who learn a new strategy but do not explain. We tested three hypothesized mechanisms through which explanations might facilitate strategy generalization: more accurate recall of the new strategy's procedures; increased selection of the new strategy over competing strategies; or more effective management of the new strategy's goal
