Strategic development.
Strategic development is more diverse, multifaceted and eventful than previously realized. Individual children know and use multiple strategies for solving a given kind of problem; they choose adaptively among available alternatives; and they frequently discover new strategies that enhance their problem-solving abilities. A recently formulated computer simulation (SCADS) indicates how associative and metacognitive processes work together to produce adaptive choices among existing strategies and discovery of useful new approaches.
