22 Important Montessori Terms

Montessori Thrive • August 23, 2021

Montessori education can feel like a whole separate world of its own sometimes. The classrooms look different, the methods are definitely different, and even the language is a whole lot different from what you might hear elsewhere.

We decided it might be helpful to highlight some terms that may sound foreign to folks who aren’t very familiar with Montessori. Some of the terms are completely unique to us, and some are just used in unique ways in the context of Montessori. Are there any you think we’ve missed? Let us know!

albums: A series of binders filled with lessons and illustrations that are created by Montessori guides during their training. They are typically organized by subject and contain all of the specifically-prescribed steps and methods for presenting materials and lessons to children. Even the most experienced guide refers back to these, and they are invaluable.

Casa dei Bambini: In Italian, this translates to Children’s House . This was the name of Dr. Maria Montessori’s first school which opened in Rome in 1907. Casa is also the name sometimes used to describe the Montessori program of education for children aged 3-6 years.

concrete (versus abstract): This refers to a type of learning and thinking experienced by younger children. When a child explores a skill by using specially designed materials, they are likely understanding the skill concretely. As they deepen their understanding and are able to comprehend the skill without the use of materials we refer to this as abstract. For example, a six-year-old using the stamp game to add numbers into the thousands is working concretely, but an eight-year-old who completes the same calculation on paper without materials is working abstractly.

control of error: Montessori materials are usually autodidactic, meaning the child is able to teach themselves. Most materials are designed with a control of error, or some type of mechanism that allows the child to recognize on their own whether they have made a mistake. This allows for immediate correction and a sense of empowerment for the child. Your child’s guide can show you many examples of this.

cosmic education: The Montessori elementary curriculum is based on the concept of cosmic education . Based on the developmental needs of children aged 6-12 years, as well as the Montessori aim to develop citizens that are more deeply connected with the earth, many of the lessons and units of study teach the interconnectedness of all things. This allows children to have a framework in which they may discover themselves and their place in the universe.

cultural subjects: This refers to the studies of science, history, and geography.

Erdkinder: A German word meaning children of the land , Dr. Maria Montessori coined this term as a name for the adolescent program, as she recognized their need to engage in physical work and envisioned the program taking place on a working farm.

false fatigue: While anyone observing a Montessori classroom during the morning work cycle (see work cycle for more) will notice deep engagement by the children, there is often a noticeable shift around 10:30. At this time it appears that the children have lost all focus and the room becomes a bit more noisy. Rather than redirecting the children, if the adults allow this period to occur, the children are usually able to independently re-engage after a short time

grace and courtesy: A specific area of study during the primary (ages 3-6) years, this aims to teach children how to appropriately interact with others. While they receive formal lessons during these years, the work is continued (although utilizing a more flexible format) throughout their Montessori education.

guide: the term used for a Montessori educator, as it more accurately describes their role.

indirect (versus direct) preparation: Learning activities that lay a foundation for future skills without explicitly teaching them are considered indirect preparation. For example, three- and four-year olds in our programs use a small tool for pin punching (perforating pieces of paper into specific shapes) that allows them to develop their fine motor skills and finger grip in preparation for the physical act of writing.

isolation: Isolation of a skill means that the child is meant to focus solely on one specific goal. If a five-year-old is asked to write a story, the guide’s focus would not be on correcting for conventional spelling, but rather to encourage their expression of ideas in written form.

Nido: In Italian this means nest, and it is the traditional Montessori name given to an infant program.

normalization: Once a child has had time to adjust to a Montessori environment, they begin to joyfully select their own work, stay engaged, and interact peacefully with others. When they achieve this state we refer to the child as normalized.

parallel play: Children under the age of six tend to be more focused on their environment than on their peers (which shifts dramatically during the elementary years). When young children work or play beside one another while actually focusing on their individual pursuits, we call this parallel play.

planes of development: After years of observing children with the perspective of a scientist, Dr. Maria Montessori noticed clear patterns and characteristics. While acknowledging the definite variation between individuals, she organized her findings into four planes of development , and based her educational methods on them.

practical life: This subject is given just as much weight in Montessori schools as we give to traditional academic subjects like math and language. Practical life can include teaching children to care for their environment, others, and themselves. Lessons are wide ranging; our students nurture plants, wash dishes, practice greeting others, sweep spills, and prepare food.

prepared environment: The term we often use in lieu of “classroom”, our guides dedicate hours of careful and intentional adjustments so that the space serves as a teacher for children. In Montessori education, one way independence is achieved is by preparing an environment in which the children are able to care for and learn by themselves, with less direct dictation from adults.

sensitive period: Dr. Montessori noticed and theorized that there are certain periods during a child’s development during which they are primed to engage in specific skills. Once that time has passed, learning such skills is not impossible, but the natural drive to do so declines, making mastery much more challenging.

sensorial: An area of study during the first plane of development (newborn to age six), in which children work to refine a wide variety of senses. There are Montessori materials that have been specifically developed to aid in this process.

work: In Montessori environments, the lines between play and work are blurred. We tend to view a child’s actions through the lens of development and learning, so that even the most seemingly mundane of tasks serves an important purpose and is considered work .

work period/work cycle: This is the term given to a dedicated period of time during which Montessori students work independently and receive individual and/or small group lessons with a guide. Depending upon the school and the age of the children, it can range anywhere from two to three hours. Dr. Montessori believed such a lengthy stretch of time was critical to allowing children to become deeply engaged in their work.

Montessori education has been in existence for over a century, but does it actually work? Dr. Angeline Stoll Lillard spent years researching this question, and her book, Montessori: The Science Behind the Genius, is a must-read. In her book, Dr. Lillard identifies eight principles at the heart of Montessori education. What’s key is that these Montessori principles align with what developmental science tells us about how humans actually learn. The remarkable thing is that Dr. Maria Montessori arrived at most of these insights through careful observation of children, decades before the research existed to corroborate how children learn. In this two-part blog post, we’ll examine these eight principles and the connected research. PRINCIPLE ONE: Movement and Learning Are Deeply Entwined In most traditional classrooms, children are still expected to sit still, as if stillness is a prerequisite for learning. In Montessori, we understand how movement and thinking are intertwined. And research backs this up. Studies have found that physical activity improves cognition, judgment, memory, and social reasoning. Moving the body isn't a break from learning. Rather, the movement is often the learning (and this is even more so for younger children!). Montessori materials are designed to be touched, carried, sorted, and manipulated. Children working with the knobbed cylinder blocks are actively perceiving, making judgments, and reasoning through their hands. The same is true when children sort fabric squares by texture, shake and compare sound cylinders, or lay out bead bars to represent quantities. Every material helps children integrate their minds and bodies. Practical life activities take this even further. When children learn to pour, button, fold, or prepare food, they are engaging in organized sequences of purposeful action that develop concentration and executive function skills. What the Research Shows A Milwaukee study found that high school students who had previously attended Montessori programs significantly outperformed peers on math and science assessments, subjects that rely heavily on the kind of reasoning that, in Montessori, is first built through hands-on materials. PRINCIPLE TWO: Choice Improves Both Learning and Well-Being The freedom to choose is at the heart of Montessori education, but this isn’t just about enjoyment. Having choice measurably affects how well children learn and how they feel about themselves. In a striking series of studies, children aged seven to nine were given anagram puzzles to solve. Those who chose their own category of puzzle solved twice as many as children whose category had been chosen for them, even though the actual puzzles were identical. Those who had a choice also spent far more time voluntarily working on puzzles during free time. The key finding is that the perception of control (even in small things) activates a fundamentally different relationship to the work. Children who feel in control tend to engage more deeply, persist longer, and take more ownership of their learning. In a Montessori classroom, children choose their own work throughout the day. Importantly, Dr. Lillard notes that this freedom is always paired with responsibility, and that too many choices can be as demotivating as none. The Montessori environment offers meaningful, bounded choice. Rather than an overwhelming array, each classroom has a selection of purposeful materials designed to match children’s developmental readiness. Choice and concentration are closely connected, too. When children choose work that genuinely engages them, they're far more likely to reach a deep state of focus, or what psychologists call a “flow state.” PRINCIPLE THREE: Children Learn Best When They're Genuinely Interested This sounds obvious, of course! It makes sense that we learn better when we are interested. However, think about this in terms of how classrooms are typically structured. If interest is one of the most powerful drivers of learning, then organizing a school day around a single curriculum delivered to the whole class at once works against almost every child in the room. Dr. Montessori understood children's interests as biological signals pointing toward what their developing minds most need to engage with at that moment in their lives. These windows of opportunity, or "sensitive periods,” are particular stretches of development during which children are uniquely primed to absorb certain kinds of learning. During these windows, learning that matches the child's inner readiness can be extraordinarily effortless and lasting. The role of interest is why Montessori materials are designed to be beautiful, engaging, and self-correcting. The sensorial materials, for example, aren't only teaching discrimination of size or color. They are designed to help children become more interested in noticing the world around them. The adult’s role is to observe carefully and offer new lessons at the moment a child's interest is most alive. PRINCIPLE FOUR: Rewards Undermine the Motivation They're Meant to Build Offering children external rewards (e.g., stickers, prizes, praise for being smart) for activities they already enjoy reliably reduces their intrinsic motivation to do those things later. What the Research Shows Researchers identified preschoolers who loved drawing with markers. They then told one group they would receive a "Good Player Award" for drawing (a fancy certificate with a gold star). Weeks later, the children who had expected the reward used the markers far less than they had before, and half as much as children who had never been offered a reward at all. Expecting a reward had turned something they loved into something they did for a prize. And when the prize was gone, so was much of the pleasure. Rewards like sticker charts, gold stars, and even grades and honor rolls, shift children’s relationship to learning from "I do this because it interests me" to "I do this to get the reward." When the reward is taken away, children’s inner drive has often already weakened. In Montessori classrooms, feedback comes through the work itself, which includes many self-correcting materials, so children discover their own errors without external judgment. The goal is to keep children's relationship to learning intrinsic, personal, and durable. This doesn't mean feedback is absent, though! What matters is the kind of feedback. Research by psychologist Carol Dweck found that praising children for effort (e.g., "you worked really hard on that”) produces dramatically better outcomes than praising ability (e.g., “you’re so smart”). Children praised for effort choose harder challenges, persist longer after failure, and actually improve their performance over time. Children praised for their intelligence begin avoiding challenges, fearing that failure will expose them as not as smart as they were told they were. In our following blog post, we’ll look at the next four Montessori principles outlined in Dr. Angeline Stoll Lillard’s book, Montessori: The Science Behind the Genius: Children Learn Powerfully from Each Other Meaningful Context Makes Learning Richer and More Lasting How Adults Interact with Children Shapes Everything Order in the Environment Supports Order in the Mind In the meantime, schedule a tour here in North Austin to see the principles in action!
