The Montessori philosophy was established by Dr. Maria Montessori, a noted Italian educator, physicist, and scientist. In 1907, she opened her first center for children, called the Casa dei Bambini (Italian for “Children’s House”) in one of the slum districts of Rome. The center hosted children that were disadvantaged and unschooled. In the beginning, the children were unruly and unmanageable, but they soon showed great interest in puzzles, materials that they could manipulate, preparing meals, and caring for their environment. Soon after, Dr. Maria Montessori observed that the children displayed calmness, long periods of
concentration, and sense of order. The children absorbed knowledge from their environment and surroundings, in effect teaching themselves.
Dr. Maria Montessori designed learning materials and set up a prepared learning environment that nurtured children's natural curiosity and inclination to learn from their surroundings.
News of the success of Dr. Maria Montessori's schools spread across the globe. It's popularity led to the establishment of Montessori schools in different parts of the world. And in 1911, the first Montessori school opened in the United States of America.
