Montessori Education is based on the principles developed by Maria Montessori, who opened her first school for children of low-income workers in an apartment building in Rome in 1907. The school was called "Casa dei Bambini", Home for Children. This first "Casa" was furnished with a teachers table, a stove, a blackboard, some chairs, group tables for the children and a cabinet filled with materials that Montessori developed in her earlier career when she researched how to teach kids who experience some form of mental disability. Maria Montessori created the materials after she realized that students seem to understand complex concepts better when they engaged all their senses. Activities at this first school included personal care, such as dressing and undressing, care of the environment like sweeping, dusting and gardening. Otherwise they were free to move around and play with the materials. Montessori did not teach herself but instead oversaw the classroom work of her teachers. Montessori observed that children showed episodes of deep concentration and multiple repetitions of the same activity. Given free choice, kids showed more interest in practical activities and the materials than normal toys, sweets or other rewards. Over time spontaneous self-discipline emerged. Montessori concluded that working independently children seemed to reach new levels of autonomy and become self-motivated learners. She began to see the role of the teacher as a facilitator of young human beings who are free to move and act within the limits of a prepared environment. The goal: to grow children to become independent and responsible adults who share a love for learning.
