Constructivism views knowledge as a constructed entity unique to each individual (we all construct our own knowledge of reality). Knowledge cannot be transferred from one person to another, rather, each must construct their own.Les Vygotsky was a Russian psychologist who was interested in education and learning. He died in 1934, and for many years his research was unknown outside of the Soviet Union. He theorized that learning develops through interactions, categorized by two forces, the Zone of Proximal develeopment and scaffolding. ZPD is the area of thinking just beyond the students current reach, but achievable through assistance. Scaffolding is the provision of help on an as-is needed basis. Students are encouraged by engaging in discussion, often being prompted by questions or subtle hints by the teacher
One educational professor in The Netherlands wrote:
Knowledge is not a disease, you can not transfer it.
