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. Popular elements include mixed-age classrooms, student freedom (including their choices of activity), long blocks of uninterrupted work time, and specially trained teachers. Scientific studies regarding the Montessori method are mostly positive, with a 2017 review stating that "broad evidence" exists for its efficacy. Credit: Wikipedia
