This volume presents 24 practical examples from Montessori free work—each tested and illustrated with numerous photos—demonstrating how performance can be appreciated and evaluated in this context. Against the backdrop of Maria Montessori's understanding of the child and their ability to create and develop themselves, the educational concept of performance is explained and linked to societal expectations. The demand for a competence-oriented approach, which should guide performance evaluation, is examined and connected to free work in the sense of Maria Montessori.
