The effect of self-observation on children's problem solving

The effects of self-observation on children's problem solving were investigated. Children (N = 124) aged 6-8 years attempted to solve the 3-disc Tower of Hanoi problem. After pretesting, children were grouped into those who (a) practiced solving the(c) observed problem independently, (b) received instruction on the most efficient solution, a videotape recording of their previous attempt, and (d) served as a control. Subsequently, children were immediately tested on the 3-disc problem and a more difficult 4-disc problem. They were tested again 1 week later. Performance was most improved for children inwere maintained the practice and video conditions on the 4-disc problem. Improvements over the 1-week interval. Unique characteristics of video self-observation are discussed.
