““...Montessori decided her teachers must each write their own textbook based on their own understanding of Montessori education... her own personal guidebook to refer to, revise, and add to throughout her teaching career. ...By writing her own guidebook, the Montessori teacher is forced to think through her personal approach to the materials and the children on a deeper level than if she were merely handed someone else's answers. This policy of asking each teacher to state her own understanding of Montessori philosophy is consistent with a philosophy and method of education that asks children to discover their own answers, instead of expecting to appropriate and substitute someone else's experiences for their own.””
