Did you really see, what you think you saw?

Observation in the different planes of development


The greatest challenge to observation lies in our own preconceptions, prejudgments, and expectations. Montessori training focuses on discovering and transforming such obstacles within ourselves. But another great challenge is making the time to observe. Sometimes, when we observe it feels as if we aren’t ‘working’. But in fact, observation is the foundation of Montessori work. Embracing that fact will be a big step towards committing the time every day throughout the day to observe and discover – without prejudice – what children constantly reveal through their own activity. And only on the basis of those revelations can we plan effective responses.

“We ourselves have lost this deep and vital sensitiveness, and in the presence of children in whom we see it reviving, we feel as if we were watching a mystery being unfolded. It shows itself in the delicate act of free choice, which a teacher untrained in observation can trample on before she even discerns it, much as an elephant tramples the budding flower about to blossom in its path.”

Maria Montessori - The Absorbent Mind, p. 248
