Montessori & Stage Theory
Rebecca Lingo • July 10, 2023

Trees start out small and then generally keep their form as they get progressively bigger and stronger. Children, however, change so much as they develop. Think about the transformations that happen from a newborn baby to a running toddler to a nine-year-old playing soccer to an adolescent driving a car. They almost don’t even seem like the same being as when they began!


Prior to the mid-1800s, people considered human development to be linear. A child was considered to be like a young adult who just got older and bigger, like a tree. However, the study of psychology changed the way we look at human development. Psychologists began to realize that humans pass through a sequence of different stages at different ages. This understanding of development as a progression was termed Stage Theory.

 

Origins of Stage Theory

 

Stage theories were popular during the time that Dr. Maria Montessori was developing her pedagogy. Stage theories take development and break it down into characteristically distinct stages assigned to specific ages. The theory assumes that certain characteristics are going to be developed during each stage. Stage theory also postulates that because certain aspects of development are supposed to happen during a particular stage, there are some innate powers available to individuals during that time. Those innate powers help individuals acquire the developmental progress for that stage. Stage theories also imply that there is also going to be a sequence to development and that stages can’t be skipped. The outcomes of one stage become the foundation for the following stage. 

 

A number of Dr. Montessori’s predecessors, contemporaries, and students were likely influencing her work, and likely she was influencing theirs. Some key individuals include: Jean-Jacque Rousseau, Sigmund Freud, Erik Erikson, Jean Piaget, Lawrence Kohlberg, and Gail Sheehy.


Montessori’s Model: Planes of Development

 

Dr. Montessori didn’t develop stage theory but used this construct to help her better understand human development. What is different about Montessori’s stage theory is that it doesn’t focus on a particular aspect of development. Rather her framework is holistic and incorporates physical, social, emotional, and intellectual development.

 

Dr. Montessori called her holistic stage theory the “planes of development.” Each plane is a distinct psychological learning period that spans about six years: birth to six, six to twelve, twelve to eighteen, and eighteen to twenty-four. Each plane is characterized by the physical and psychological changes that take place, as well as the environmental needs of each plane. 


Dr. Montessori observed how the differences between each plane were so dramatic that the shift from one stage of development to the next was metamorphic. The same individual emerges from each plane, unrecognizable from the individual they were when they entered the previous plane.

 

Characteristics of the Planes of Development

 

Dr. Montessori passionately describes how education needs to follow these periods of development, to be sensitive to the rebirth that is happening for each individual. 

 

“The child does not grow in a uniform way day by day, at the same rate. In growth there are crises, somewhat like the metamorphosis of the insects….In fact, it is the child himself who will be the guide of education.” – Dr. Maria Montessori, The Four Planes of Education

 

The metamorphosis that happens in different periods of growth demonstrates the unique needs, behaviors, and characteristics of children at different ages. 

 

Since each developmental plane is distinct, it follows that the needs of individuals will also be distinct. Plus, at each stage children require different things from their environment. Furthermore, the successful completion of one phase sets individuals up for successful development in the next stage. 

 

Dr. Montessori was an optimist and didn’t see this need for successful completion of each stage as being fatalistic. She thought that missed opportunities within a plane of development could be overcome with conscious effort and work. Granted, this development wouldn’t happen as easily as if happened at the right time, but Dr. Montessori thought that if individuals applied themselves and worked, they could overcome some of these obstacles. The work accomplished outside of an intended plane, however, would never be as fully integrated as if it had happened during its intended time.


Montessori’s Unique Approach

 

When Dr. Montessori developed her theory on the planes of development, she didn’t describe development in a culturally specific context or time. She described universal aspects of human development in all cultures.

 

Two other aspects set Montessori’s work apart from stage theory. One was that she focused on what is normal development for children rather than what is abnormal. She focused on the positive strengths instead of deficiencies. She demonstrated that highlighting strengths is not to the detriment of the areas that need support. Also, she articulated her theory of the planes of development and went a step further to develop an educational approach that supports it. 


At Wheaton Montessori School and in Montessori schools all over the world, everything we do for children–all of our methods, materials, and environments–is reflective of our understanding of the planes of development. We understand the needs of children in the different stages of their development and know we have a profound responsibility to support those needs.

Montessori Mayhem? Pint-Sized Pandemonium? When I give tours of the Elementary classrooms or welcome new parents to the Elementary program at Wheaton Montessori School, some parents believe that students are allowed complete freedom, as if the classrooms are a beautiful den of chaos and anarchy. Indeed, this is one of the biggest misconceptions about Montessori education. (The biggest misconception being, in my experience, that Montessori isn’t “real world” education. But as we say in our lessons, “That’s a story for another day.”) While Montessori classrooms DO give children the freedoms they require and deserve, it’s not an unlimited free-for-all with an adult watching from an observation chair! Freedom is always balanced with responsibility, to oneself and to the community. These values, freedom and responsibility, are essential for creating a happy, busy, humming classroom where children thrive. What Does Freedom Mean in Our Classroom? “Freedom” in the classroom means that students are encouraged to make choices about their learning. Just as in our Primary classrooms at Wheaton Montessori School, students are free to choose their work, their seat, and their work partners. They are free to move about the classroom and do not need to raise their hands to visit the restroom, get a drink of water, or ask a question. Let’s look at a few of these freedoms more closely. Students are Free to Choose Their Work. For example, they may choose which book to read, choose a work partner to research a chosen topic, or practice a tricky bit of a lesson over and over. They are also able to choose how they will show their understanding. They might present their understanding through a poster, a diorama, a model, a handmade book, or an enormous amount of cardboard and hot glue. These choices empower students to take charge of their education and express themselves in ways that suit their interests and strengths, something a standardized test or a worksheet can never do. However, freedom in the classroom ALWAYS has limits. For example, students are free to choose their work, but choosing NOT to work is not an option. They are free to choose their work from the lessons that have been presented to them. While students may choose their reading material, it must be appropriate for their reading level and classroom guidelines. When students select a partner, they must do so respectfully and inclusively. When students create projects and work output, they must do so with care, make proper use of materials, and in a way that shows what they understand about their topic. Additionally, these choices should never disrupt their own learning and construction, or that of their peers. The Role of Responsibility In a true Montessori classroom, freedom comes with responsibility. And that responsibility can sometimes be uncomfortable at first. Students are expected to care for classroom materials, such as returning books and lesson materials to the shelf, taking part in classroom jobs, keeping a record of their work in their work journals, and handling art supplies properly. They are responsible for practicing their lessons and completing chosen follow-up work, listening attentively during lessons or when a classmate is sharing a presentation or thought, and helping classmates when needed and available. A student is not free to use materials in a way that damages or wastes the classroom supplies or puts anyone in harm’s way. Freedom within our classroom never allows for harming oneself, others, or the classroom materials. Healthy boundaries, limits, and structures are consistently communicated in advance with clarity and respect, ensuring practicality and alignment within the community. Classroom expectations and rules are collaboratively developed and agreed upon by the community. In order to foster a positive learning environment, both students and teachers are expected to adhere to the shared expectations and responsibilities. When necessary, the classroom adult will address students and reiterate expectations and boundaries in a firm yet considerate manner. This balanced approach is effective only when maintained consistently throughout each day. What Might it Look Like When the Balance Needs to Shift? The adults in the classroom are constantly observing the children to be sure that each child has as much freedom as they are ready for, providing them space, room, and opportunities to show their strengths, and make their own choices throughout the day. When that freedom is too much, a teacher might need to provide more lessons in how to use materials that have been damaged or used improperly, limit work partner choices, or have a student sit with the teacher while they practice lessons or work with precious art materials. The adults will be watching for the perfect moment to allow the child increased freedom within the classroom, and within the limits of the understood responsibilities. How Freedom and Responsibility Work Together Finding the right mix of freedom and responsibility is something we work on together every day in our classroom. Montessori teachers are specially trained to guide this balance, helping students practice important skills like making good choices, solving problems, and learning self-control. When children are trusted to make decisions, they also learn to take responsibility for those choices. Experiencing the natural consequences of their actions helps them become kind, thoughtful, and capable members of their community who understand how their choices affect others. What Does This Have to Do with Parents? Your support at home makes a big difference. By working together, we can help your child thrive both at school and at home. Encouraging your child to take responsibility for their actions and decisions reinforces what they learn in class. Yes, it can be uncomfortable, but it is necessary. It also becomes easier, more comfortable, and needs to be practiced less often when practiced consistently (like most things!). This supportive consistency across settings, at home and at school, helps children feel confident, cared for, and increasingly independent.
