In simple terms
Scaffolding is temporary support that lets a learner do a task they could not yet manage alone, and it is built to be taken away. The name is borrowed from building sites, where the scaffold holds a structure up only until it can stand by itself.
That second half is the part people forget. Support that never fades is not scaffolding, because the learner never takes over the work. [2]
How it works
Wood, Bruner and Ross introduced the term in 1976 for the cognitive support a teacher gives so a learner can solve a problem beyond their unaided reach. [1] Their model lists six jobs the helper does: directing attention to what matters, simplifying the task, keeping the learner going, marking the critical features, managing frustration, and demonstrating an idealized version of the solution. [1]
It is the practical face of Vygotsky’s zone of proximal development, the gap between what a learner can do alone and what they can do with help. [1]
Two features define the real thing. Support is contingent, meaning the level of help responds to the last attempt: a failure brings more explicit guidance, a success brings less. [2] And support fades, transferring responsibility to the learner as they take it on. [2]
Why it matters
Scaffolding names the difference between helping someone and doing it for them. Worked examples, sentence starters, partly completed problems and pre-taught vocabulary are all scaffolds, and each one is supposed to come with a plan for its removal. [2]
The concept is not settled. The original model assumes the helper already knows the solution, which does not hold in peer collaboration where nobody does, and yet learners there still support one another. Researchers have argued on that basis that the idea needs rethinking. [1]
Where you will see it
- A teacher working through a method aloud before students try it [2]
- Writing frames and sentence starters in language classrooms [2]
- Pre-teaching vocabulary before a difficult text [2]
- Clinical and trade apprenticeships, where supervision is reduced step by step
Example
He scaffolded the first three problems by working through them aloud, then handed over the fourth with no prompts at all.
Often confused with
Differentiation gives different learners different materials or tasks. Scaffolding breaks one task into parts, supports each part, and then withdraws. [2]
Key facts
- Wood, Bruner and Ross introduced the term in 1976 for cognitive support that lets a learner solve a task they could not solve alone.1
- The original model lists six functions, including directing attention, simplifying the task, maintaining motivation, marking critical features and demonstrating solutions.1
- Scaffolding puts Vygotsky's zone of proximal development into practice, the gap between what a learner can do alone and what they can do with help.1
- Support is contingent: more explicit help follows a failed attempt, less directive help follows a success.2
- Fading, the gradual withdrawal of support as the learner takes over, is part of the definition rather than an optional extra.2
- The original model assumes the helper already knows the solution, an assumption that breaks down in peer collaboration.1

It is contingent on the learner's last attempt, and it fades as responsibility transfers to the learner.
