A key concept in this theory is the Zone of Proximal Development (ZPD), which refers to the difference between what a learner can do independently and what they can achieve with guidance. Within this zone, learning is most effective because the learner is challenged but supported. Related to ZPD is the role of a More Knowledgeable Other (MKO)—someone, such as a teacher, parent, or peer, who provides
