Montessori
"The centerpiece of the Montessori approach is allowing children to learn on their own while being guided by the teacher. Montessori teachers do not correct work and hand it back with lots of red marks. A child's work is not graded. The teacher assesses what the child has learned and then guides him into new areas of discovery."
This description of a Montessori school was written by Ruth Hurvitz of The Montessori School in Wilton, CT. "The Montessori School's culture is devoted to helping each child grow toward independence by building confidence, competence, self-esteem and respect for others. More than an approach to education, Montessori is an approach to life. The program at The Montessori School, both in philosophy and pedagogy, is based on the scientific research work of Dr. Maria Montessori and on AMI Montessori training. The School respects children as self-directed individuals and fosters their growth toward independence and social responsibility, while creating a joyful, diverse and family-oriented community."
