Such scaffolding occurs in the context of parents helping their children, teachers helping their students, coaches helping their players, and more advanced learners helping less advanced ones (Freund, 1990; Gauvain, 1992; Rogoff, Ellis, & Gardner, 1984; Wood, Bruner, & Ross, 1976). The goal of such interactions is for the less knowledgeable learner to construct strategies that the more advanced already possess.
