What it shows
Vygotsky’s zone of proximal development (Vygotsky 1978) as three regions along a line of increasing task difficulty: what the learner can do unaided, what they can do only with guidance (the zone), and what is out of reach even with help.
Scaffolding is marked under the zone alone: help that is reduced as the skill grows. The term comes from Wood, Bruner and Ross (1976), not from Vygotsky. One example runs across all three regions: a learner driver after a few lessons.
How to read it
Can do unaided: holds the wheel correctly and starts the car.
Zone of proximal development: scans the road and changes lanes with the instructor’s prompts.
Cannot do yet: drives on a highway in heavy traffic, out of reach even with the instructor beside them.
As the instructor’s prompts are withdrawn, tasks move from the zone into what the learner can do unaided.
The three regions
- Can do unaided: the learner solves it alone.
- Zone of proximal development: can do it with guidance, not yet alone.
- Cannot do yet: out of reach even with help.
- Scaffolding: help that is reduced as the skill grows (term from Wood, Bruner and Ross 1976).
Ways to use it in teaching
When planning a lesson, sort the tasks into the three regions for a particular group and aim the main activity at the middle one.
Ask trainee teachers to name the scaffolding they would give for the middle task, and how they would withdraw it.
Replace the driving example with a skill from your own subject.
