The Lost ARC / Unit 8 ARC 207 short lesson, about 20 seconds
The Zone of Proximal Development
Captions available
The idea
The book borrows Lev Vygotsky's zone of proximal development: the space between what a person can do alone and what they can do with guidance.
In practice
A new analyst unable to build the model alone, able to build it with a colleague beside her.
Where people slip
The book places the best development inside that zone, where challenge meets enough support to succeed.
