Dynamic zone at the edge of one’s competence in which the development of new intellectual skills and competencies takes place. It may be characterized as a distance between an agent’s independent problem-solving capability and capability achieved when the agent relies on a caregiver’s support or some other external scaffolding (Vygotsky, 1962). From the perspective of expansive learning
theory, ZPD is a distance between practices
prevailing and stabilized within an activity system
and cultural-historically available and societally most advanced practices (Engeström, 1987).
