Change processes in development: The concept of coactive scaffolding

The concept of scaffolding is generally invoked to refer to the ways in which a more expert individual assists a child by performing a part a task or by otherwise directing or supporting a child's task-related actions. A coactive systems model of development provides a framework for examining other ways in which person-environment relations may scaffold development. From a coactive systems view, the unit of analysis for understanding development is the coactive person-environment system. Within such a system, although individual actors exert control over their actions, thoughts and feelings, action is the product of coactions among each element of the system over time. From this view, coactive scaffolding refers to any process outside of an individual's direct control that functions to direct individual action toward novel or higher-order forms. Three broad categories (and subtypes) of coactive scaffolding are proposed and illustrated: ecological scaffolding, social scaffolding, and self-scaffolding.
