Vygotsky is the shinning star among learning theorists for educators today. His work is held in high acclaim and widely taught in education schools. This has certainly been a long time coming! Vygotsky died in 1934 and was largely unknown in the west for many years before his works began to be translated. Today his theory is seen as a major part of constructivism, which by most accounts is the dominant theory in educational circles.
The concept of the Zone of Proximal Development (ZPD) that Vygotsky created has been very influential and is know to most teachers. His idea that students should be working in groups on challenging tasks with assistance from someone who is more capable is widely embraced in education.
