Scaffolding
When does help actually help?
Scaffolding is temporary, adjustable support that lets learners complete a task they cannot yet manage alone, tuned to their current performance and withdrawn as they take over.
Watch a parent help a toddler with a shoe: hold it steady, point to the heel, then let go as the child gets the idea. In 1976, David Wood, Jerome Bruner and Gail Ross described this kind of help. They studied a tutor working with three- to five-year-olds who were building a pyramid from interlocking wooden blocks. They called it scaffolding: the adult takes charge of the parts of a task the learner cannot yet manage, so the learner can focus on the parts within reach. They listed six functions, including getting the child interested, simplifying the task, marking critical features and controlling frustration.
The metaphor is often credited to Vygotsky, but the 1976 paper framed it as tutoring, not through his theory. The explicit link to the zone of proximal development, the gap between what a learner can do alone and with help, came later. Courtney Cazden made it in 1979, and Bruner himself took it up in the 1980s.
What turns help into scaffolding? Reviewing a decade of research, van de Pol, Volman and Beishuizen (2010) found three shared features. Support is contingent, meaning adjusted to what the learner is doing now; it fades over time; and responsibility passes to the learner. For language classrooms, Hammond and Gibbons (2005) separate designed-in scaffolding, planned into sequences such as the teaching–learning cycle, from contingent scaffolding offered in the moment. A writing frame used unchanged all year may help learners finish tasks. But if nothing is ever handed over, it is no longer scaffolding.
In actionHelp that steps back
- T
- Tell me about your weekend.
- S
- I go to Vũng Tàu.
- T
- You... (points back over her shoulder)
- S
- I went to Vũng Tàu!
- T
- Lovely. Who with?
- S
- My family. We eat seafood... ate seafood.
The gesture marks the critical feature without supplying the form. In the last turn the learner corrects herself unprompted: responsibility is shifting from teacher to learner.
In the classroom
- 1
Plan the fade: for a speaking task, give a full model dialogue on day one, a skeleton with prompts on day two, and only a situation card on day three.
- 2
When a learner is stuck, offer the least help first: a pause, then a hint (Check the verb.), then a choice, then the answer, the logic of graduated prompting in dynamic assessment.
- 3
Mark critical features before learners write: highlight the moves in a model paragraph, then ask learners to find the same moves in a partner’s draft.
Myth and reality
Scaffolding is anything a teacher does to make a task easier.
Scaffolding is support calibrated to what a learner can nearly do and designed to be withdrawn. Help that ignores the learner’s current performance, or never fades, simplifies the task without building independence.
Reflect
Which supports in your classroom have outlived their purpose, and how would you find out whether learners still need them?
Worth a minute before your next lesson, or a conversation in the staffroom.

This paper gave the term its classic educational meaning. Cazden (1979) explicitly linked it to Vygotsky’s zone of proximal development, a pairing Bruner later adopted. Shvarts and Bakker (2019) trace earlier uses of the metaphor to Bernstein, Luria and Vygotsky’s own notebooks.
