Why did Montessori teachers remain in the background during children’s work?

In the Montessori system, teachers remain in the background to prioritize student initiative and self-direction, which are the cornerstones of the Maria Montessori philosophy.12

Rather than lecturing or directing the children, the teacher’s role is to provide and demonstrate the use of specialized "didactic apparatus"—concrete materials designed to engage a child's senses and mental capacity during specific "periods of sensitivity". By stepping back, the teacher allows the child to handle these materials independently, fostering an environment where the child can engage in spontaneous, voluntary work. This approach supports the belief that children have a natural drive to learn and are capable of self-education when provided with an environment that encourages individual initiative.2
