This Haiku Deck illustrates LS Vygotsky's theory of learning and development as defined by the concept of the zone of proximal development -- the distance between what someone can do without assistance and what they could achieve with the strategic guidance of peers, teachers or other resources. Educators should create learning situations that challenge learners to draw on what they know and can do, while offering "strategic guidance" (Reiser, 2009) tor enhance or build new knowledge, skills and practices. Thus, Vygotksy's theory anticipates that learning leads development.
