Zone of proximal development
The zone of proximal development (ZPD) is a concept in educational psychology. It represents the space between what a learner is capable of doing unsupported and what the learner cannot do even with support. It is the range where the learner is able to perform, but only with support from a teacher or a peer with more knowledge or expertise (a "more knowledgeable other"). [1] The concept was introduced, but not fully developed, by psychologist Lev Vygotsky (1896–1934) during the last three years of his life.[2] Vygotsky argued that a child gets involved in a dialogue with the "more knowledgeable other", such as a peer or an adult, and gradually, through social interaction and sense-making, develops the ability to solve problems independently and do certain tasks without help. Following Vygotsky, some educators believe that the role of education is to give children experiences that are within their zones of proximal development, thereby encouraging and advancing their individual learning skills and strategies.[3]
Challenges[edit]
Scaffolding in education does have some boundaries. One of the largest hurdles to overcome when providing ample support for student learning is managing multiple students. While scaffolding is meant to be a relatively independent process for students, the initial phase of providing individual guidance can easily be overseen when managing large classrooms. Thus, time becomes a critical factor in a scaffolding lesson plan. In order to accommodate more learners, teachers are often faced with cutting parts of lessons or dedicating less time to each student.[24] In turn, this hastened class time might result in loss of interest in students or even invalid peer-teaching. Cognitive abilities of the student also play a significant role in the success of scaffolding. Ideally, students are able to learn within this zone of proximal development, but this is often not the case. Recognizing students' individual abilities and foundation knowledge can be a challenge of successful scaffolding. If students are evidently less prepared for this learning approach and begin to compare themselves to their peers, their self-efficacy and motivation to learn can be hindered.[25] These hurdles of scaffolding and the zone of proximal development are important to acknowledge so that teachers can find solutions to the problems or alter their teaching methods.
