Scaffolding Scaffolding support refers to teachers supporting pupils in the early stages of learning a task. This form of support is based on Vygotsky’s idea of the zone of proximal development. The teacher sets a task at a level that is not too easy and not too difficult. The task should be sufficiently challenging to motivate the learner and to build upon and extend the pupil’s existing level of knowledge, competence or performance. Types of scaffold include modelling, guiding, thinking through and mediation. Reciprocal teaching is a type of scaffolded instruction.
