Vygotsky believes that the relationship between education and psychological development has three aspects:
1, "zone of proximal development" thought: the dynamic state of children's development level is determined by education and teaching, that is, teaching creates the zone of proximal development.
2. Teaching should be ahead of development: teaching should guide and promote development.
3. The best period of study: the education and teaching of children must be based on the premise of biological maturity and must also precede the formation of psychological function. The best period of education and teaching is the period when children are most easily influenced by relevant education and teaching.
