Self-construction describes how children build themselves through active engagement with their environment. Unlike traditional education models that view children as passive recipients of knowledge, Montessori sees learning as a self-directed process in which children freely choose activities, guided by an inner drive, that support their cognitive, social, and emotional development. Through hands-on work, exploration, and repetition, children refine their abilities, develop independence, and form their unique characters. The role of the guide is to provide a prepared environment that supports this natural process.
