Guided by Marxist philosophy, Vygotsky, as an ex-Soviet famous psychologist, founded the unique social-cultural-historical theory, in which Vygotsky’s psychological developmental theory is the most typical representative. Vygotsky’s psychological developmental theory mainly concerned with the theory of behavior, mediation, internalization which relate to man’s development of higher mental functions and zone of proximal development. Combined with the western ideas about constructionism, the social constructionism was founded based on Vygotsky’s psychological developmental theory. From then on, the construction of the learning theory of social constructionism gives great implication to our country’s modern education.
