Her method is still used today in school around the world and was created by observing children while there were playing. They work in silence, speak softly or in whispers. The basis of her method and learning are sensory working tools. Children evaluate their knowledge through mistakes and experiments. The materials used by the children are made so that the child does not need to be attended by a teacher for control. The child should be allowed to work alone and on that way enable him to get to know the world and build independence.
