The term 'scaffolding', now tied to Vygotsky's zone of proximal development, was introduced by:

1. Scaffolding means the graded help an adult or able peer gives so a child can work within the ZPD. 2. It is so closely linked with Vygotsky that many assume he coined it. 3. In fact Vygotsky never used the term. 4. It was developed by Jerome Bruner, David Wood and Gail Ross when applying the ZPD to education. 5. Later work (Wass and Golding) found the hardest tasks a learner can do with scaffolding give the greatest gains. 6. So the term comes from Wood, Bruner and Ross. **Why the other options fail:** - Vygotsky himself is the main trap. - Piaget and Inhelder worked on cognitive stages. - Kohlberg and Gilligan worked on moral development. _Source: Wikipedia, "Zone of proximal development", section "Scaffolding" (revision 1365068534)_
