Maria Montessori is one of the most significant figures in the history of education. She dedicated her life to improving and promoting child development. She was the first female physician in Italy and the founder of the Montessori pedagogy, which places the child at the center. Maria Montessori views the child as an active participant in the educational process. A child is born with potential, and adults should discover and further develop that potential. Her method is still applied in preschools and schools worldwide, and it originated from observing children during play. She observed spontaneity in children's actions and discovered their need for repetition because repeating actions provides children with a sense of security. She believed that children should acquire knowledge and experiences through all their senses and that they build their knowledge through mistakes and experiments. The aim of this paper is to present Montessori pedagogy, explain its foundations, and its positive impact on a child's growth and development.
