The Montessori method of education was developed by Italian physician Maria Montessori. Emphasizing independence, it views children as naturally eager for knowledge and capable of initiating learning in a sufficiently supportive and well-prepared learning environment. It discourages some conventional measures of achievement, such as grades and tests. Montessori developed her theories in the early 1900s through scientific experimentation with her students; the method has since been used in many parts of the world, in public and private schools alike.
