The Montessori approach, much like any science, has its own set of vocabulary and terminology. Montessorians share a very specific set of brief references that evoke the world of the child as described by Maria Montessori. The Glossary of Montessori Terms relates to the theory and practice for the Primary (3-6) level. It was prepared by the late Annette Haines (Montessori Training Centre of St. Louis) at the request of Molly O'Shaughnessy (Montessori Centre of Minnesota) to accompany her lecture at the Joint Annual Refresher Course, held in Tampa, Florida in February 2001.
Absorbent Mind
A mind able to absorb knowledge quickly and effortlessly. Montessori 
said the child from birth to six years has an absorbent mind.
Adaptation
Related to the idea of an absorbent mind (Haines, 1993) is a special 
power of the young child that can be called the power of adaptation. 
This power is a process whereby the young child uses the environment to 
develop and, in so doing, becomes a part of that environment. The young 
child absorbs the culture of her time and place, taking in all the 
spirit, the customs, the ambitions/aspirations and attitudes of a 
society simply by living in that society.
Analysis of Movement
A technique used by Montessori teachers. The adult, when showing a 
complex action to a child, breaks it down into its parts and shows one 
step at a time, executing each movement slowly and exactly. The action 
thus becomes a sequence of simple movements and the child has a greater 
chance of success when 'given the liberty to make use of them.' 
(Montessori, 1966, p. 108)
Children's House
The English name for Montessori's Casa dei Bambini (Italian). A place 
for children from 3-6 years to live and grow. Everything necessary for 
optimal human development is included in a safe and secure environment.
Classification
Sorting. Allocating or distributing according to common characteristics.
 The young child engages in classification activities because the 
process is essential for the construction of the intellect. The 
Montessori classroom offers many opportunities for classification.
Concentration
Recognising that 'the longer one does attend to a topic the more mastery
 of it one has,' the great American psychologist William James remarked,
 'An education which should improve this faculty would be the education 
par excellence.' (1892/1985, p. 95) Montessori, who knew of James, set 
out to do just that. She believed that if environments could be prepared
 with 'objects which correspond to...formative tendencies' (1949/1967, 
p. 169) the child's energy and interest would become focused on that 
aspect of the environment which corresponded to the developmental need.
Concrete to Abstract
A progression both logical and developmentally appropriate. The child is
 introduced first to a concrete material that embodies an abstract idea 
such as size or colour. Given hands-on experience, the child's mind 
grasps the idea inherent in the material and forms an abstraction. Only 
as the child develops, is she gradually able to comprehend the same idea
 in symbolic form.
Control of Error
A way of providing instant feedback. Every Montessori activity provides 
the child with some way of assessing his own progress. This puts the 
control in the hands of the learner and protects the young child's 
self-esteem and self-motivation. Control of error is an essential aspect
 of auto-education.
Coordination of Movement
One of the major accomplishments of early childhood. Through the child's
 own effort, she wills herself to refine her muscular coordination and 
consequently acquires increasingly higher levels of independent 
functioning. Because of this developmental need, children are drawn to 
activities that involve movement and especially to those which demand a 
certain level of exactitude and precision.
Creativity/Imagination
Imagination involves the forming of a mental concept of what is not 
actually present to the senses. Creativity is a product of the 
imagination and results from the mental recombining of imagined ideas in
 new and inventive ways. Both are dependent on mental imagery formed 
through sensorial experience.
Cycle of Activity
Little children, when engaged in an activity which interests them, will 
repeat it many times and for no apparent reason, stopping suddenly only 
when the inner need which compelled the child to activity has been 
satisfied. To allow for the possibility of long and concentrated work 
cycles, Montessori advocates a three-hour uninterrupted work period.
Development of the Will
The ability to will, or choose to do something with conscious intent, 
develops gradually during the first phase of life and is strengthened 
through practice. The Montessori environment offers many opportunities 
for the child to choose. Willpower, or self-control, results from the 
many little choices of daily life in a Montessori school.
Deviations
Behaviour commonly seen in children that is the result of some obstacle 
to normal development. Such behaviour may be commonly understood as 
negative (a timid child, a destructive child, etc.) or positive (a 
passive, quiet child). Both positive and negative deviations disappear 
once the child begins to concentrate on a piece of work freely chosen.
Discipline from Within
Self-discipline. The discipline in a well-run Montessori classroom is 
not a result of the teacher's control or of rewards or punishments. Its 
source comes from within each individual child, who can control his or 
her own actions and make positive choices regarding personal behaviour. 
Self-discipline is directly related to development of the will.
Exercises of Practical Life
One of the four areas of activities of the Montessori prepared 
environment. The exercises of Practical Life resemble the simple work of
 life in the home: sweeping, dusting, washing dishes, etc. These 
purposeful activities help the child adapt to his new community, learn 
self-control and begin to see himself as a contributing party of the 
social unit. His intellect grows as he works with his hands; his 
personality becomes integrated as body and mind function as a unit.
False Fatigue
A phenomenon observed in Children's Houses around the world-often at 
approximately 10 a.m. The children seem to lose interest in work, their 
behaviour becomes disorderly and the noise level rises. It may appear as
 if the children are tired. However, if the directress understands this 
is simply false fatigue, they will return to work on their own and their
 work will be at an even higher level than before.
Grace and Courtesy
An aspect of Practical Life. Little lessons which demonstrate positive 
social behaviour help the young child adapt to life in a group and arm 
her with knowledge of socially acceptable behaviour: practical 
information, useful both in and out of school.
Help from Periphery
The periphery is that part of the child that comes into contact with 
external reality. The child takes in impressions through the senses and 
through movement. Help from the periphery means presenting objects and 
activities in such a way so as to evoke purposeful movement on the part 
of the child. 'We never give to the eye more than we give to the hand.' 
(Standing, 1957, p. 237)
Human Tendencies
A central tenet of Montessori philosophy is that human beings exhibit 
certain predispositions that are universal, spanning age, cultural and 
racial barriers; they have existed since the dawn of the species and are
 probably evolutionary in origin. 'Montessori stresses the need to serve
 those special traits that have proved to be tendencies of Man 
throughout his history.' (Mario Montessori, 1966, p. 21)
Independence
Not depending on another‚ with various shades of meaning.' (OED, p. 836)
 Normal developmental milestones such as weaning, walking, talking, etc.
 can be seen as a series of events which enable the child to achieve 
increased individuation, autonomy and self-regulation. Throughout the 
four planes of development, the child and young adult continuously seek 
to become more independent. It is as if the child says, Help me to help 
myself.
Indirect Preparation
The way nature has of preparing the intelligence. In every action, there
 is a conscious interest. Through this interest, the mind is being 
prepared for something in the future. For example, a young child will 
enjoy the putting together of various triangular shapes, totally unaware
 that because of this work his mind will later be more accepting of 
geometry. Also called remote preparation. the deeper educational purpose
 of many Montessori activities is remote in time.
Indirect Presentation
Because of the absorbent nature of the young child's mind, every action 
or event can be seen as a lesson. It is understood that children learn 
by watching other children work or by overseeing a lesson given to 
another. In the same way, they quickly absorb the behaviour patterns and
 the language used by the family, the neighborhood children and even TV.
Isolation of a Difficulty
Before giving a presentation, the Montessori teacher analyses the 
activity she wants to show to the child. Procedures or movements that 
might prove troublesome are isolated and taught to the child separately.
 For example, holding and snipping with scissors, a simple movement, is 
shown before cutting curved or zigzag lines; folding cloths is shown 
before table washing, an activity requiring folding. A task should 
neither be so hard that it is overwhelming, nor so easy that it is 
boring.
Language Appreciation
From the very first days in the Montessori classroom, children are given
 the opportunity to listen to true stories about known subjects, told 
with great expression. Songs, poems and rhymes are a part of the daily 
life of the class. The teacher models the art of conversation and 
respectfully listens to her young students. Looking at beautiful books 
with lovely, realistic pictures is also a part of language appreciation.
Learning Explosions
Human development is often not slow and steady; acquisitions seem to 
arrive suddenly, almost overnight, and with explosive impact. Such 
learning explosions are the sudden outward manifestation of a long 
process of internal growth. For example, the explosion of spoken 
language around two years of age is the result of many months of inner 
preparation and mental development.
Mathematical Mind
All babies are born with mathematical minds, that is, they have a 
propensity to learn things which enhance their ability to be exact and 
orderly, to observe, compare, and classify. Humans naturally tend to 
calculate, measure, reason, abstract, imagine and create. But this vital
 part of intelligence must be given help and direction for it to develop
 and function. If mathematics is not part of the young child's 
experience, his subconscious mind will not be accepting of it at a later
 date.
Maximum Effort
Children seem to enjoy difficult work, work which tests their abilities 
and provides a sense of their growing power. They exult in giving their 
maximum effort. For example, a tiny child will struggle to carry a tray 
with juice glasses or push a heavy wheelbarrow whereas school-age 
children, if allowed to make up their own problems will prefer to sink 
their teeth into a challenging equation (I + 2 + 3 + 4... + 10)2 rather 
than drill on 3 + 5 = ... and 6 + 2 = ... .
Mixed Ages
One of the hallmarks of the Montessori method is that children of mixed 
ages work together in the same class. Age groupings are based on 
developmental planes. Children from 3-6 years of age are together in the
 Children's House; 6-9 year olds share the lower elementary and the 
upper elementary is made up of 9-12 year olds. Because the work is 
individual, children progress at their own pace; there is cooperation 
rather than competition between the ages.
Normalisation
If young children are repeatedly able to experience periods of 
spontaneous concentration on a piece of work freely chosen, they will 
begin to display the characteristics of normal development: a love of 
work, an attachment to reality, and a love of silence and working alone.
 Normalised children are happier children: enthusiastic, generous, and 
helpful to others. They make constructive work choices and their work 
reflects their level of development.
Obedience
Obedience is an act of will and develops gradually, showing itself 
'unexpectedly at the end of a long process of maturation.' (Montessori, 
1967, p. 257) While this inner development is going on, little children 
may obey occasionally, but be completely unable to obey consistently. As
 their will develops through the exercise of free choice, children begin
 to have the self-discipline or self-control necessary for obedience.
Points of Interest
Montessori realised that if children spent too long a time on a complex 
task or failed to master the necessary details, the exercise would cease
 to interest them. Therefore she suggested that points of interest be 
interspersed throughout each activity. These points guide the child 
toward his or her goal and stimulate repetition and interest by offering
 immediate feedback, or what Montessori called control of error. The 
child's performance becomes refined through trial and error, the points 
of interest acting as signposts along the path to success.
Prepared Environment
The Montessori classroom is an environment prepared by the adult for 
children. It contains all the essentials for optimal development but 
nothing superfluous. Attributes of a prepared environment include order 
and reality, beauty and simplicity. Everything is child-sized to enhance
 the children's independent functioning. A trained adult and a large 
enough group of children of mixed ages make up a vital part of the 
prepared environment.
Presentation
The adult in a Montessori environment does not teach in the traditional 
sense. Rather she shows the child how to use the various objects and 
then leaves her free to explore and experiment. This act of showing is 
called a presentation. To be effective, it must be done slowly and 
exactly, step by step, and with a minimum of words.
Psychic Embryo
The first three years of life is a period of mental creation, just as 
the 9 months in utero is a period of physical creation. The brain awaits
 experience in the environment to flesh out the genetic blueprint. Since
 so much mental development occurs after birth, Montessori called the 
human infant a psychic embryo.
Repetition
The young child's work is very different from the adult's. When an adult
 works, he sets out to accomplish some goal and stops working when the 
object has been achieved. A child, however, does not work to accomplish 
an external goal but rather an internal one. Consequently, she will 
repeat an activity until the inner goal is accomplished. The unconscious
 urge to repeat helps the child to coordinate a movement or acquire some
 ability.
Sensitive Periods
Young children experience transient periods of sensibility, and are 
intrinsically motivated or urged to activity by specific sensitivities. A
 child in a sensitive period is believed to exhibit spontaneous 
concentration when engaged in an activity that matches a particular 
sensitivity. For example, children in a sensitive period for order will 
be drawn to activities that involve ordering. They will be observed 
choosing such activities and becoming deeply concentrated, sometimes 
repeating the activity over and over, without external reward or 
encouragement. Young children are naturally drawn towards those specific
 aspects of the environment which meet their developmental needs.
Sensorial Materials
The sensorial materials were created to help young children in the 
process of creating and organising their intelligence. Each 
scientifically designed material isolates a quality found in the world 
such as colour, size, shape, etc. and this isolation focuses the 
attention on this one aspect. The child, through repeated manipulation 
of these objects, comes to form clear ideas or abstractions. What could 
not be explained by words, the child learns by experience working with 
the sensorial materials.
Simple to Complex
A principle used in the sequence of presentations in a Montessori 
classroom. Children are first introduced to a concept or idea in its 
simplest form. As they progress and become capable of making more 
complex connections, they are eventually able to handle information that
 is less isolated.
Socialisation
'The process by which the individual acquires the knowledge and 
dispositions that enable him to participate as an effective member of a 
social group and a given social order.' (Osterkorn, 1980, p. 12) 
'Optimal social learning takes place when the children are at different 
ages.' (Hellbr_gge, 1979, p. 14)
Sound Games
Many children know the alphabet but have not analysed the sounds in 
words nor are they aware that words are made up of separate sounds 
(phonemic awareness). From the age of two (or as soon as the child is 
speaking fluently), sound games can make them aware of the sounds in 
words. In England, they use the nursery game "I Spy." The sound of the 
letter and not the letter name is pronounced.
Three-Hour Work Cycle
Through years of observation around the world, Montessori came to 
understand that children, when left in freedom, displayed a distinct 
work cycle which was so predictable it could even be graphed. This 
cycle, with two peaks and one valley, lasted approximately three hours. 
In Montessori schools children have three hours of open, uninterrupted 
time to choose independent work, become deeply engaged, and repeat to 
their own satisfaction.
Vocabulary Enrichment
The young child's vocabulary increases exponentially in the years from 
3-6. To feed this natural hunger for words, vocabulary is given: the 
names of biology, geometry, geography, and so forth, can be learned as 
well as the names of qualities found in the Sensorial Material. The 
child's absorbent mind takes in all these new words 'rapidly and 
brilliantly.' (Montessori, 1946, p. 10)
Work
From an evolutionary perspective, the long period of childhood exists so
 children can learn and experiment in a relatively pressure-free 
environment. Most social scientists refer to this pressure-free 
experimentation as play (e.g., see Groos, 1901), although Montessori 
preferred to call this activity the work of childhood. Children 
certainly are serious when engaged in the kind of play that meets 
developmental needs and, given freedom and time, will choose purposeful 
activities over frivolous make-believe ones.
