Our Montessori Dictionary

LakeCreek Montessori School • December 3, 2024

We recognize that Montessori education can have some lingo that might need a little explanation. So in this Montessori Dictionary post, we’re going to focus on a few terms (some familiar, some perhaps not so familiar) that apply to both the early childhood years and beyond. 


When possible, we’ve included some quotes from Dr. Maria Montessori and we encourage you to take a look at her work. Dr. Montessori was a woman well before her time and her books, such as From Childhood to Adolescence and To Educate the Human Potential, can be a source of insight and inspiration!


Grace and Courtesy


Grace and courtesy is an essential aspect of Montessori environments and supports children as they develop social relationships. Grace is how we move through the space around us, and courtesy is how we treat each other. 


In the Montessori primary classroom, grace and courtesy is considered one of the areas of practical life. For example, adults give lessons on how to interrupt, how to accept an offering, how to offer help, or how to introduce oneself. These lessons are offered in small groups and the technique used is role-playing. Little social scenarios are acted out and provide a model for behavior that is situational. Like all other learning activities, grace and courtesy lessons are practiced and repeated. They provide a respectful way of learning expectations and aiding social skills before they are needed.


Grace and courtesy is never offered as a form of punishment or correction. We make sure children don’t experience embarrassment by being corrected by adults on the spot, as this makes children feel disrespected and not safe. Dr. Montessori reminds us of this in The Secret of Childhood: “I have come to appreciate the fact that children have a deep sense of personal dignity. Adults, as a rule, have no concept of how easily they are wounded and oppressed.” In time, if we offer these grace and courtesy lessons, and give children a safe place to practice, children will eventually perform these skills independently. 


Human Tendencies


Human tendencies are unconscious, universal drives that support our adaptation to our particular time and place. All humans are born with innate needs and drives and are wired to adapt to their environment. The human tendencies – to orient, explore, order, abstract, imagine, calculate, work, be exact and repeat, perfect oneself, and communicate and associate with others – help aid this adaptation.  


Dr. Montessori alluded to human tendencies when she wrote about the inner drive she observed in children and how this drive helps individuals construct themselves to develop into maturity: “Their behavior led us to become aware of a fundamental truth, namely that the child works for his own inner development and not to reach an exterior aim and that when he has done this work he has not really developed a special ability but he has developed something in himself.” 


Prepared Environment


The Montessori environment is carefully prepared so that children can satisfy their human tendencies and thus develop to their fullest potential. The prepared environment takes into consideration what children need at their particular stage of growth, and as individuals on their own trajectory of development. The prepared environment consists of the physical and psychic aspects of the environment, of which the adult is a key part. 


Through interactions in a prepared environment, children can construct who they are as human beings. As they go through this process of self-construction in their environment, children learn, grow, adapt, and create. The prepared environment is part of the triad of the child, the environment, and the adult, all of which are interconnected components. 


Sensitive Periods/Sensitivities


Dr. Montessori was first and foremost a scientist and she was interested in what was happening prior to observable signs of human development. She was curious about what was going on in the mind before the skill manifested itself. For example, she wanted to know what was happening during the many months prior to children speaking their first word. 


Without the high-tech tools that neuropsychologists and psychologists now have to measure brain activity, Dr. Montessori had to rely upon observation. She watched children, took notes, and made charts about what they did. As a result, she discovered that a particular object or aspect of the environment would have an irresistible draw for children. This attraction would last for some time. Children would keep going back to the same activity or element of the environment and would be continually drawn to it. Then the day would come when it held no more interest and something new would be attractive. 


Dr. Montessori observed this phenomenon over and over again, which led her to believe that there must be something innate in children that was driving this interest. Building upon the work of biologists, Dr. Montessori adopted the term, sensitive period, to describe transitory periods of psychic development. Beyond the Montessori world, sensitive periods are now referred to as critical periods or windows of opportunity.

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!
