The aim of this paper is to consider and examine the impact of key principles of the Montessori

Method on pre-school children’s development. The Montessori Method is one of the contemporary

and alternative education methods that is globally practiced by Montessori educators. It is viewed

as a child-centered method of schooling. Since Montessori education has existed for about 150

years, it is true that the social, cognitive, emotional and physical development of the children had

already been well examined. There are key principles in each Montessori setting that enhance

children’s individual development. In a Montessori learning environment, children are shown

respect by teachers and classmates and they have the greater opportunity to ′absorb′ the

environment. The sensitive periods are extremely significant for the appropriate development of

children. The prepared environment is designed to facilitate independent learning and exploration

by the child, which opens the door to children’s self-education. Moreover, Montessori children

have a freedom of choice and movement that indicates the way this method meets the needs of

children. This paper explores the Montessori Philosophy, evaluates its effect on children’s

development and discusses its core principles in depth.
