The students' building of their mental lives is an arduous, ceaseless and delicate labor which no one can do for them.
To aid them in this construction we need to create a place where the sensitive periods, the human tendencies and the planes of development are all being observed. Where each child works at their own rate according to their own interests.
Like a seed that will not grow unless it is given water, soil, sunshine and air, a child will not flourish unless given a safe and enriching environment that meets their developmental needs. This allows them to build their unique selves - a pumpkin seed wont create a sunflower no matter how much we wish it.
The Montessori environment needs to fulfill all of the different needs of the child to aid them in their own self construction.
In the classroom, the Montessori teacher prepares an environment which allows the children to come in contact with the qualities and facts of the world as presented through the Montessori materials. The teacher is the link between each child and this prepared environment. This role alternates between a direct and indirect one, as the teacher closely and continuously observes each child and watches for the next manifestation.
When a class first begins, all the children need continual help in their relationships with one another and care of the environment. They need to make a connection to the teacher and know that she cares for them and understands them. Gradually, in response to their new environment and the teacher's careful guidance, the children develop into a harmonious, independent community. The teacher becomes a participant/observer in a community of children.
This environment enhances the children's inner discipline, concentration, belief in themselves and belief in each other. They develop a sense of responsibility and an appreciation for the world and the things and people within it, achieving harmony with life.
A true Montessori environment will have aided the child in the construction of their own life, a fulfilled life that is a part of the greater good.
