Originally called a “directress”, the Montessori teacher functions as a designer of the environment, a resource person, role model, demonstrator, record-keeper and meticulous observer of each child’s behavior and growth. The teacher facilitates learning. The teacher remains in the background, guiding each child in the use of the materials (which are selfcorrective) and then leaves the child to practice and perfect the understanding of the lesson. The teacher deals with the child as an individual worthy of respect and the only active agent in the learning process. Extensive training is required for a full Montessori credential.
