At the under age six level, Montessori emphasizes learning through all five senses, not just through listening, watching, or reading. Children in Montessori classes learn at their own, individual pace and according to their own choice of activities from hundreds of possibilities. The are not required to sit and listen to a teacher talk to them as a group, but are engaged in individual or group activities of their own, with materials that have been introduced to them 1:1 by the teacher who knows what each child is ready to do. Learning is an exciting process of discovery, leading to concentration, motivation, self-discipline, and a love of learning.
Above age 6 children learn to do independent research, arrange field trips to gather information, interview specialists, create group presentation, dramas, art exhibits, musical productions, science projects, and so forth. There is no limit to what they created in this kind of intelligently guided freedom. There no text books or adult-directed group lessons and daily schedule. There is great respect for the choices of the children, but they easily keep up with or surpass what they would be doing in a more traditional setting. There is no wasted time and children enjoy their work and study. The children ask each other for lessons and much of the learning comes from sharing and inspiring each other instead of competing with each other.
Montessori classes place children in three-year-or-more age groups (3-6, 2.5-6, 6-12, and so on), forming communities in which the older children spontaneously share their knowledge with the younger ones. Montessori represents an entirely different approach to education.
