It is success oriented in that almost everything is self-teaching and self-correcting. The children learn by doing and by experimentation. The environment is specifically prepared for the children to allow them to interact with it freely and unfettered, everything is child sized, and safe for children to touch and use.
The main goal of Montessori is to provide a stimulating, child oriented environment that children can explore, touch, and learn without fear. An understanding parent or teacher is a large part of this child's world. The end result is to encourage lifelong learning, the joy of learning, and happiness about one's path and purpose in life.
