Vygotsky? The nearest development zone? The theory and its enlightenment are: children's development has two stages: one stage is the current development level of children, and the next stage is the level that children can only complete with the help of adults. Between these two stages is the development area closest to the child. That is, children have been able to do it, but not independently but only under the guidance of education. The recent development zone determines the possibility of teaching, and teaching should also aim at this. Vygotsky wrote:? Teaching should not aim at the yesterday of children's development, but at the tomorrow of children's development. ? Only under this condition can teaching be ahead of development. So the role of education and teaching is to create? The nearest development zone? Promote or accelerate children's internal development and create conditions for their psychological development. Education should be ahead of development. Educators should not only understand the current situation of children, but also judge the trends and trends of children's development, so that children can? Jump and reach out? Help children bravely meet challenges, stimulate thinking, creativity and willpower, and experience the happiness of success. ?
