Scaffolding is an instructional technique where a teacher provides supports to help students learn new concepts and skills before gradually removing the supports as learning improves. It is based on Vygotsky's zone of proximal development and aims to make students self-reliant learners. When used correctly and with customized lesson plans, scaffolding can effectively introduce new subjects to diverse students. However, determining when to remove supports can be difficult as students learn at different paces. Overall, scaffolding provides a bridge between direct and indirect learning if implemented properly in an encouraging environment.
