Dr. Maria Montessori, the creator of what is called “The Montessori Method”, based her educational program on her scientific observation of young children’s behaviour. As the first woman physician to graduate from the University of Rome, Maria Montessori became involved with education as a doctor treating children labelled as retarded. In 1907 she was invited to establish a childcare centre in the San Lorenzo slums of Rome. She called it a “Children’s house” and based the program on her observations that young children learn best in a home like setting, filled with developmentally appropriate materials that provide experiences contributing to the growth of self motivated, independent learners. She carried her message throughout the world and aspects of her methodology are now used in every sphere of education. Prior to her death in 1952, Maria Montessori was three times nominated for the Nobel Peace Prize and takes her place in history as a woman who changed the world.
