Question

Quizplus · Accepted Answer

Piaget's experiments with balancing a scale showed that children in the concrete operational stage, typically ages 7-11, use trial-and-error problem solving to figure out how to balance the scale. This stage is characterized by logical thinking, but not yet the complex, abstract reasoning of the formal operational stage. The unrealistic thought characteristic of younger children is not applicable in this context.
