    What is a Theory?

    Students sometimes feel intimidated by theory; even the phrase, “Now we are going to look at some theories...” is met with blank stares and other indications that the audience is now lost. But theories are valuable tools for understanding human behavior; in fact, they are proposed explanations for the “how” and “whys” of development. Have you ever wondered, “Why is my three year old so inquisitive?” or “Why are some fifth graders rejected by their classmates?” Theories can help explain these and other occurrences. Developmental theories offer explanations about how we develop, why we change over time and the kinds of influences that impact development.

    A theory guides and helps us interpret research findings as well. It provides the researcher with a blueprint or model to be used to help piece together various studies. Think of theories as guidelines much like directions that come with an appliance or other object that requires assembly. The instructions can help one piece together smaller parts more easily than if trial and error are used.

    Theories can be developed using induction in which a number of single cases are observed and after patterns or similarities are noted, the theorist develops ideas based on these examples. Established theories are then tested through research; however, not all theories are equally suited to scientific investigation. Some theories are difficult to test but are still useful in stimulating debate or providing concepts that have practical application. Keep in mind that theories are not facts; they are guidelines for investigation and practice, and they gain credibility through research that fails to disprove them.20

    Let’s take a look at some key theories in Child Development.

    Sigmund Freud’s Psychosexual Theory

    We begin with the often controversial figure, Sigmund Freud (1856-1939). Freud has been a very influential figure in the area of development; his view of development and psychopathology dominated the field of psychiatry until the growth of behaviorism in the 1950s. His assumptions that personality forms during the first few years of life and that the ways in which parents or other caregivers interact with children have a long-lasting impact on children’s emotional states have guided parents, educators, clinicians, and policy-makers for many years. We have only recently begun to recognize that early childhood experiences do not always result in certain personality traits or emotional states. There is a growing body of literature addressing resilience in children who come from harsh backgrounds and yet develop without damaging emotional scars (O’Grady and Metz, 1987). Freud has stimulated an enormous amount of research and generated many ideas. Agreeing with Freud’s theory in its entirety is hardly necessary for appreciating the contribution he has made to the field of development.

    Freud’s theory of self suggests that there are three parts of the self.

    • The id is the part of the self that is inborn. It responds to biological urges without pause and is guided by the principle of pleasure: if it feels good, it is the thing to do. A newborn is all id. The newborn cries when hungry, defecates when the urge strikes.
    • The ego develops through interaction with others and is guided by logic or the reality principle. It has the ability to delay gratification. It knows that urges have to be managed. It mediates between the id and superego using logic and reality to calm the other parts of the self.
    • The superego represents society’s demands for its members. It is guided by a sense of guilt. Values, morals, and the conscience are all part of the superego.

    The personality is thought to develop in response to the child’s ability to learn to manage biological urges. Parenting is important here. If the parent is either overly punitive or lax, the child may not progress to the next stage. Here is a brief introduction to Freud’s stages.

    Table \(\PageIndex{1}\): Sigmund Freud’s Psychosexual Theory
    Name of Stage Descriptions of Stage
    Oral Stage The oral stage lasts from birth until around age 2. The infant is all id. At this stage, all stimulation and comfort is focused on the mouth and is based on the reflex of sucking. Too much indulgence or too little stimulation may lead to fixation.
    Anal Stage The anal stage coincides with potty training or learning to manage biological urges. The ego is beginning to develop in this stage. Anal fixation may result in a person who is compulsively clean and organized or one who is sloppy and lacks self-control.
    Phallic Stage The phallic stage occurs in early childhood and marks the development of the superego and a sense of masculinity or femininity as culture dictates.
    Latency Latency occurs during middle childhood when a child’s urges quiet down and friendships become the focus. The ego and superego can be refined as the child learns how to cooperate and negotiate with others.
    Genital Stage

    The genital stage begins with puberty and continues through adulthood. Now the preoccupation is that of sex and reproduction.

    Strengths and Weaknesses of Freud’s Theory

    Freud’s theory has been heavily criticized for several reasons. One is that it is very difficult to test scientifically. How can parenting in infancy be traced to personality in adulthood? Are there other variables that might better explain development? The theory is also considered to be sexist in suggesting that women who do not accept an inferior position in society are somehow psychologically flawed. Freud focuses on the darker side of human nature and suggests that much of what determines our actions is unknown to us. So why do we study Freud? As mentioned above, despite the criticisms, Freud’s assumptions about the importance of early childhood experiences in shaping our psychological selves have found their way into child development, education, and parenting practices. Freud’s theory has heuristic value in providing a framework from which to elaborate and modify subsequent theories of development. Many later theories, particularly behaviorism and humanism, were challenges to Freud’s views.22

    Main Points to Note About Freud’s Psychosexual Theory

    Freud believed that:

    • Development in the early years has a lasting impact.
    • There are three parts of the self: the id, the ego, and the superego
    • People go through five stages of psychosexual development: the oral stage, the anal stage, the phallic stage, latency, and the genital stage

    We study Freud because his assumptions the importance of early childhood experience provide a framework for later theories (the both elaborated and contradicted/challenged his work).

    Erik Erikson’s Psychosocial Theory

    Now, let’s turn to a less controversial theorist, Erik Erikson. Erikson (1902-1994) suggested that our relationships and society’s expectations motivate much of our behavior in his theory of psychosocial development. Erikson was a student of Freud’s but emphasized the importance of the ego, or conscious thought, in determining our actions. In other words, he believed that we are not driven by unconscious urges. We know what motivates us and we consciously think about how to achieve our goals. He is considered the father of developmental psychology because his model gives us a guideline for the entire life span and suggests certain primary psychological and social concerns throughout life.

    clipboard_e4dba872d11620670e32d7000cbc534f8.png
    Figure \(\PageIndex{2}\): Erik Erikson. (Image is in the public domain)

    Erikson expanded on his Freud’s by emphasizing the importance of culture in parenting practices and motivations and adding three stages of adult development (Erikson, 1950; 1968).

    He believed that we are aware of what motivates us throughout life and the ego has greater importance in guiding our actions than does the id. We make conscious choices in life and these choices focus on meeting certain social and cultural needs rather than purely biological ones. Humans are motivated, for instance, by the need to feel that the world is a trustworthy place, that we are capable individuals, that we can make a contribution to society, and that we have lived a meaningful life. These are all psychosocial problems.

    Erikson divided the lifespan into eight stages. In each stage, we have a major psychosocial task to accomplish or crisis to overcome. Erikson believed that our personality continues to take shape throughout our lifespan as we face these challenges in living. Here is a brief overview of the eight stages:

    Table \(\PageIndex{2}\): Erik Erikson’s Psychosocial Theory
    Name of Stage Description of Stage
    Trust vs. mistrust (0-1)

    The infant must have basic needs met in a consistent way in order to feel that the world is a trustworthy place.

    Autonomy vs. shame and doubt (1-2) Mobile toddlers have newfound freedom they like to exercise and by being allowed to do so, they learn some basic independence.
    Initiative vs. Guilt (3-5)

    Preschoolers like to initiate activities and emphasize doing things “all by myself.”

    Industry vs. inferiority (6- 11) School aged children focus on accomplishments and begin making comparisons between themselves and their classmates
    Identity vs. role confusion (adolescence) Teenagers are trying to gain a sense of identity as they experiment with various roles, beliefs, and ideas.
    Intimacy vs. Isolation (young adulthood) In our 20s and 30s we are making some of our first long-term commitments in intimate relationships.
    Generativity vs. stagnation (middle adulthood) The 40s through the early 60s we focus on being productive at work and home and are motivated by wanting to feel that we’ve made a contribution to society.
    Integrity vs. Despair (late adulthood) We look back on our lives and hope to like what we see-that we have lived well and have a sense of integrity because we lived according to our beliefs.

    These eight stages form a foundation for discussions on emotional and social development during the life span. Keep in mind, however, that these stages or crises can occur more than once. For instance, a person may struggle with a lack of trust beyond infancy under certain circumstances. Erikson’s theory has been criticized for focusing so heavily on stages and assuming that the completion of one stage is a prerequisite for the next crisis of development. His theory also focuses on the social expectations that are found in certain cultures, but not in all. For instance, the idea that adolescence is a time of searching for identity might translate well in the middle-class culture of the United States, but not as well in cultures where the transition into adulthood coincides with puberty through rites of passage and where adult roles offer fewer choices.24

    Main Points to Note About Erikson’s Psychosocial Theory

    Erikson was a student of Freud but focused on conscious thought.

    • His stages of psychosocial development address the entire lifespan and suggest primary psychosocial crisis in some cultures that adults can use to understand how to support children’s social and emotional development.
    • The stages include: trust vs. mistrust, autonomy vs. shame and doubt, initiative vs. guilt, industry vs. inferiority, identity vs. role confusion, intimacy vs. isolation, generativity vs. stagnation, and integrity vs. despair.

    Behaviorism

    While Freud and Erikson looked at what was going on in the mind, behaviorism rejected any reference to mind and viewed overt and observable behavior as the proper subject matter of psychology. Through the scientific study of behavior, it was hoped that laws of learning could be derived that would promote the prediction and control of behavior.25

    Ivan Pavlov

    Ivan Pavlov (1880-1937) was a Russian physiologist interested in studying digestion. As he recorded the amount of salivation his laboratory dogs produced as they ate, he noticed that they actually began to salivate before the food arrived as the researcher walked down the hall and toward the cage. “This,” he thought, “is not natural!” One would expect a dog to automatically salivate when food hit their palate, but BEFORE the food comes? Of course, what had happened was . . . you tell me. That’s right! The dogs knew that the food was coming because they had learned to associate the footsteps with the food. The key word here is “learned”. A learned response is called a “conditioned” response.

    clipboard_ef8d66edb399bcd0bdf8476f250556dfe.png
    Figure \(\PageIndex{3}\): Ivan Pavlov. (Image is in the public domain)

    Pavlov began to experiment with this concept of classical conditioning. He began to ring a bell, for instance, prior to introducing the food. Sure enough, after making this connection several times, the dogs could be made to salivate to the sound of a bell. Once the bell had become an event to which the dogs had learned to salivate, it was called a conditioned stimulus. The act of salivating to a bell was a response that had also been learned, now termed in Pavlov’s jargon, a conditioned response. Notice that the response, salivation, is the same whether it is conditioned or unconditioned (unlearned or natural). What changed is the stimulus to which the dog salivates. One is natural (unconditioned) and one is learned (conditioned).

    Let’s think about how classical conditioning is used on us. One of the most widespread applications of classical conditioning principles was brought to us by the psychologist, John B. Watson.

    John B. Watson

    John B. Watson (1878-1958) believed that most of our fears and other emotional responses are classically conditioned. He had gained a good deal of popularity in the 1920s with his expert advice on parenting offered to the public.

    clipboard_ed3f3bf3842621bbea201b0a5e1d46c92.png
    Figure \(\PageIndex{4}\): John B. Watson. (Image is in the public domain)

    He tried to demonstrate the power of classical conditioning with his famous experiment with an 18-month-old boy named “Little Albert”. Watson sat Albert down and introduced a variety of seemingly scary objects to him: a burning piece of newspaper, a white rat, etc. But Albert remained curious and reached for all of these things. Watson knew that one of our only inborn fears is the fear of loud noises so he proceeded to make a loud noise each time he introduced one of Albert’s favorites, a white rat. After hearing the loud noise several times paired with the rat, Albert soon came to fear the rat and began to cry when it was introduced. Watson filmed this experiment for posterity and used it to demonstrate that he could help parents achieve any outcomes they desired, if they would only follow his advice. Watson wrote columns in newspapers and in magazines and gained a lot of popularity among parents eager to apply science to household order.

    Operant conditioning, on the other hand, looks at the way the consequences of a behavior increase or decrease the likelihood of a behavior occurring again. So let’s look at this a bit more.

    B.F. Skinner and Operant Conditioning

    B. F. Skinner (1904-1990), who brought us the principles of operant conditioning, suggested that reinforcement is a more effective means of encouraging a behavior than is criticism or punishment. By focusing on strengthening desirable behavior, we have a greater impact than if we emphasize what is undesirable. Reinforcement is anything that an organism desires and is motivated to obtain.

    clipboard_e7a7e2d34a1c1889f105cc504d02a6253.png
    Figure \(\PageIndex{5}\): B. F. Skinner. (Image is in the public domain)

    A reinforcer is something that encourages or promotes a behavior. Some things are natural rewards. They are considered intrinsic or primary because their value is easily understood. Think of what kinds of things babies or animals such as puppies find rewarding.

    Extrinsic or secondary reinforcers are things that have a value not immediately understood. Their value is indirect. They can be traded in for what is ultimately desired.

    The use of positive reinforcement involves adding something to a situation in order to encourage a behavior. For example, if I give a child a cookie for cleaning a room, the addition of the cookie makes cleaning more likely in the future. Think of ways in which you positively reinforce others.

    Negative reinforcement occurs when taking something unpleasant away from a situation encourages behavior. For example, I have an alarm clock that makes a very unpleasant, loud sound when it goes off in the morning. As a result, I get up and turn it off. By removing the noise, I am reinforced for getting up. How do you negatively reinforce others?

    Punishment is an effort to stop a behavior. It means to follow an action with something unpleasant or painful. Punishment is often less effective than reinforcement for several reasons. It doesn’t indicate the desired behavior, it may result in suppressing rather than stopping a behavior, (in other words, the person may not do what is being punished when you’re around, but may do it often when you leave), and a focus on punishment can result in not noticing when the person does well. Not all behaviors are learned through association or reinforcement. Many of the things we do are learned by watching others. This is addressed in social learning theory.

    Social Learning Theory

    Albert Bandura (1925-) is a leading contributor to social learning theory. He calls our attention to the ways in which many of our actions are not learned through conditioning; rather, they are learned by watching others (1977). Young children frequently learn behaviors through imitation

    clipboard_e94828c69d46c8608e8b9979b7b9d784f.png
    Figure \(\PageIndex{6}\): Albert Bandura. (Image by Albert Bandura is licensed under CC BY-SA 4.0)

    Sometimes, particularly when we do not know what else to do, we learn by modeling or copying the behavior of others. A kindergartner on his or her first day of school might eagerly look at how others are acting and try to act the same way to fit in more quickly. Adolescents struggling with their identity rely heavily on their peers to act as role-models. Sometimes we do things because we’ve seen it pay off for someone else. They were operantly conditioned, but we engage in the behavior because we hope it will pay off for us as well. This is referred to as vicarious reinforcement (Bandura, Ross and Ross, 1963).

    Bandura (1986) suggests that there is interplay between the environment and the individual. We are not just the product of our surroundings, rather we influence our surroundings. Parents not only influence their child’s environment, perhaps intentionally through the use of reinforcement, etc., but children influence parents as well. Parents may respond differently with their first child than with their fourth. Perhaps they try to be the perfect parents with their firstborn, but by the time their last child comes along they have very different expectations both of themselves and their child. Our environment creates us and we create our environment.30

    Bandura and the Bobo Doll Experiment & Today’s Children and the Media

    Other social influences: TV or not TV? Bandura (et als. 1963) began a series of studies to look at the impact of television, particularly commercials, on the behavior of children. Are children more likely to act out aggressively when they see this behavior modeled? What if they see it being reinforced? Bandura began by conducting an experiment in which he showed children a film of a woman hitting an inflatable clown or “bobo” doll. Then the children were allowed in the room where they found the doll and immediately began to hit it. This was without any reinforcement whatsoever. Not only that, but they found new ways to behave aggressively. It’s as if they learned an aggressive role.

    Children view far more television today than in the 1960s; so much, in fact, that they have been referred to as Generation M (media). The amount of screen time varies by age. As of 2017, children 0-8 spend an average of 2 hours and 19 minutes. Children 8-12 years of age spend almost 6 hours a day on screen media. And 13- to 18-year-olds spend an average of just under 9 hours a day in entertainment media use.

    The prevalence of violence, sexual content, and messages promoting foods high in fat and sugar in the media are certainly cause for concern and the subjects of ongoing research and policy review. Many children spend even more time on the computer viewing content from the internet. The amount of time spent connected to the internet continues to increase with the use of smartphones that essentially serve as mini-computers. And the ways children and adolescents interact with the media continues to change. The popularity of YouTube and the various social media platforms are examples of this. What might be the implications of this?31

    Main Points to Note About Behaviorism

    Behaviorists look at observable behavior and how it can be predicted and controlled.

    • Pavlov experimented with classical conditioning, the process of conditioning a response to stimulus (the dog’s salivating to the bell).
    • Watson offered advice to parents to show them how classical conditioning can be used. His most famous experiment was conditioning Little Albert to fear a white rate.
    • Skinner believed that reinforcing behavior is the most effective way of increasing desirable behavior. This is done through operant conditioning.
    • Bandura noted that many behaviors are not learned through any type of conditioning, but rather through imitation. And he believed that people are not only influenced by their surroundings, but that they also have an impact on their surroundings.

    Theories also explore cognitive development and how mental processes change over time.

    Jean Piaget’s Theory of Cognitive Development

    Jean Piaget (1896-1980) is one of the most influential cognitive theorists. Piaget was inspired to explore children’s ability to think and reason by watching his own children’s development. He was one of the first to recognize and map out the ways in which children’s thought differs from that of adults. His interest in this area began when he was asked to test the IQ of children and began to notice that there was a pattern in their wrong answers. He believed that children’s intellectual skills change over time through maturation. Children of differing ages interpret the world differently.

    clipboard_e0dfc83a86c36146d5dd89e06cd9b67ba.png
    Figure \(\PageIndex{7}\): Jean Piaget. (Image is in the public domain)

    Piaget believed our desire to understand the world comes from a need for cognitive equilibrium. This is an agreement or balance between what we sense in the outside world and what we know in our minds. If we experience something that we cannot understand, we try to restore the balance by either changing our thoughts or by altering the experience to fit into what we do understand. Perhaps you meet someone who is very different from anyone you know. How do you make sense of this person? You might use them to establish a new category of people in your mind or you might think about how they are similar to someone else.

    A schema or schemes are categories of knowledge. They are like mental boxes of concepts. A child has to learn many concepts. They may have a scheme for “under” and “soft” or “running” and “sour”. All of these are schema. Our efforts to understand the world around us lead us to develop new schema and to modify old ones.

    One way to make sense of new experiences is to focus on how they are similar to what we already know. This is assimilation. So the person we meet who is very different may be understood as being “sort of like my brother” or “his voice sounds a lot like yours.” Or a new food may be assimilated when we determine that it tastes like chicken!

    Another way to make sense of the world is to change our mind. We can make a cognitive accommodation to this new experience by adding new schema. This food is unlike anything I’ve tasted before. I now have a new category of foods that are bitter-sweet in flavor, for instance. This is accommodation. Do you accommodate or assimilate more frequently? Children accommodate more frequently as they build new schema. Adults tend to look for similarity in their experience and assimilate. They may be less inclined to think “outside the box.” Piaget suggested different ways of understanding that are associated with maturation. He divided this into four stages:

    Table \(\PageIndex{3}\): Jean Piaget’s Theory of Cognitive Development
    Name of Stage Description of Stage
    Sensorimotor Stage During the sensorimotor stage children rely on use of the senses and motor skills. From birth until about age 2, the infant knows by tasting, smelling, touching, hearing, and moving objects around. This is a real hands on type of knowledge.
    Preoperational Stage In the preoperational stage, children from ages 2 to 7, become able to think about the world using symbols. A symbol is something that stands for something else. The use of language, whether it is in the form of words or gestures, facilitates knowing and communicating about the world. This is the hallmark of preoperational intelligence and occurs in early childhood. However, these children are preoperational or pre-logical. They still do not understand how the physical world operates. They may, for instance, fear that they will go down the drain if they sit at the front of the bathtub, even though they are too big.
    Concrete Operational Children in the concrete operational stage, ages 7 to 11, develop the ability to think logically about the physical world. Middle childhood is a time of understanding concepts such as size, distance, and constancy of matter, and cause and effect relationships. A child knows that a scrambled egg is still an egg and that 8 ounces of water is still 8 ounces no matter what shape of glass contains it.
    Formal Operational During the formal operational stage children, at about age 12, acquire the ability to think logically about concrete and abstract events. The teenager who has reached this stage is able to consider possibilities and to contemplate ideas about situations that have never been directly encountered. More abstract understanding of religious ideas or morals or ethics and abstract principles such as freedom and dignity can be considered.

    Criticisms of Piaget’s Theory

    Piaget has been criticized for overemphasizing the role that physical maturation plays in cognitive development and in underestimating the role that culture and interaction (or experience) plays in cognitive development. Looking across cultures reveals considerable variation in what children are able to do at various ages. Piaget may have underestimated what children are capable of given the right circumstances.33

    Main Points To Note About Piaget’s Theory of Cognitive Development

    Piaget, one of the most influential cognitive theorists, believed that

    • Understanding is motivated by trying to balance what we sense in the world and what we know in our minds.
    • Understanding is organized through creating categories of knowledge. When presented with new knowledge we may add new schema or modify existing ones.

    Children’s understanding of the world of the world changes are their cognitive skills mature through four stages: sensorimotor stage, preoperational stage, concreate operational stage, and formal operational stage.

    Lev Vygotsky’s Sociocultural Theory

    Lev Vygotsky (1896-1934) was a Russian psychologist who wrote in the early 1900s but whose work was discovered in the United States in the 1960s but became more widely known in the 1980s. Vygotsky differed with Piaget in that he believed that a person not only has a set of abilities, but also a set of potential abilities that can be realized if given the proper guidance from others. His sociocultural theory emphasizes the importance of culture and interaction in the development of cognitive abilities. He believed that through guided participation known as scaffolding, with a teacher or capable peer, a child can learn cognitive skills within a certain range known as the zone of proximal development.34 His belief was that development occurred first through children’s immediate social interactions, and then moved to the individual level as they began to internalize their learning.35

    Have you ever taught a child to perform a task? Maybe it was brushing their teeth or preparing food. Chances are you spoke to them and described what you were doing while you demonstrated the skill and let them work along with you all through the process. You gave them assistance when they seemed to need it, but once they knew what to do-you stood back and let them go. This is scaffolding and can be seen demonstrated throughout the world. This approach to teaching has also been adopted by educators. Rather than assessing students on what they are doing, they should be understood in terms of what they are capable of doing with the proper guidance. You can see how Vygotsky would be very popular with modern day educators.37

    Main Points to Note About Vygotsky’s Sociocultural Theory

    Vygotsky concentrated on the child’s interactions with peers and adults. He believed that the child was an apprentice, learning through sensitive social interactions with more skilled peers and adults.

    Comparing Piaget and Vygotsky

    Vygotsky concentrated more on the child’s immediate social and cultural environment and his or her interactions with adults and peers. While Piaget saw the child as actively discovering the world through individual interactions with it, Vygotsky saw the child as more of an apprentice, learning through a social environment of others who had more experience and were sensitive to the child’s needs and abilities.38

    Like Vygotsky’s, Bronfenbrenner looked at the social influences on learning and development.

    Urie Bronfenbrenner’s Ecological Systems Model

    Urie Bronfenbrenner (1917-2005) offers us one of the most comprehensive theories of human development. Bronfenbrenner studied Freud, Erikson, Piaget, and learning theorists and believed that all of those theories could be enhanced by adding the dimension of context. What is being taught and how society interprets situations depends on who is involved in the life of a child and on when and where a child lives.

    Figure \(\PageIndex{9}\): Urie Bronfenbrenner. (Image by Marco Vicente González is licensed under CC BY-SA 4.0)

    Bronfenbrenner’s ecological systems model explains the direct and indirect influences on an individual’s development.

    Table \(\PageIndex{4}\): Urie Bronfenbrenner’s Ecological Systems Model
    Name of System Description of System
    Microsystems Microsystems impact a child directly. These are the people with whom the child interacts such as parents, peers, and teachers. The relationship between individuals and those around them need to be considered. For example, to appreciate what is going on with a student in math, the relationship between the student and teacher should be known.
    Mesosystems Mesosystems are interactions between those surrounding the individual. The relationship between parents and schools, for example will indirectly affect the child.
    Exosystem Larger institutions such as the mass media or the healthcare system are referred to as the exosystem. These have an impact on families and peers and schools who operate under policies and regulations found in these institutions.
    Macrosystems We find cultural values and beliefs at the level of macrosystems. These larger ideals and expectations inform institutions that will ultimately impact the individual.
    Chronosystem All of this happens in an historical context referred to as the chronosystem. Cultural values change over time, as do policies of educational institutions or governments in certain political climates. Development occurs at a point in time.

    For example, in order to understand a student in math, we can’t simply look at that individual and what challenges they face directly with the subject. We have to look at the interactions that occur between teacher and child. Perhaps the teacher needs to make modifications as well. The teacher may be responding to regulations made by the school, such as new expectations for students in math or constraints on time that interfere with the teacher’s ability to instruct. These new demands may be a response to national efforts to promote math and science deemed important by political leaders in response to relations with other countries at a particular time in history.

    Bronfenbrenner’s ecological systems model challenges us to go beyond the individual if we want to understand human development and promote improvements.41

    Main Points to Note About Bronfenbrenner’s Ecological Model

    After studying all of the prior theories, Bronfenbrenner added an important element of context to the discussion of influences on human development.

    • He believed that the people involved in children’s lives and when and where they live are important considerations.
    • He created a model of nested systems that influence the child (and are influenced by the child) that include: microsystems, mesosystems, the exosystem, macrosystems, and chronosystems.

    Maria Montessori 'Method'

    Maria Montessori (1870-1952) was n Italian physician and educator who developed the Montessori Method of teaching.  She grew up with an interest in education and pedagogy, eventually opening up a center for underprivileged children.  She discovered that children learn through a specialized environment, choosing what they wanted to work on and teaching themselves in the process.  Maria is best known for the philosophy of education that bears her name for over 100 years, as well as her writing on scientific pedagogy.  She developed learning materials and environments that supported a child’s innate interest in learning.  "The key areas of learning in a Montessori environment include: Practical life, sensorial, language, mathematics and culture.  She identified developmental phases, each with its own set of goals for learning: the development of individual self, social development, the ‘birth’ of the adult phase and the mature phase.  In each phase, referred to as ‘windows of opportunity’, designed classrooms, with age-appropriate tasks and materials, are provided to maximize learning during these stages" (AMSHQ, 2021). 

    Within 6 years of opening her first school, there were teacher training sites and Montessori schools on 5 continents.  Her first book "The Montessori Method" has been translated in 10 languages.  Today, more than a million children attend public Montessori schools worldwide.   

    Her classrooms are designed around three key points: the teacher, the child and the environment.  The teacher only offers guidance for building on skills as needed. The key principles of this method applied across all ages are: 

    Individual Instruction: Individual didactic materials are provided to allow children to learn at their own pace.  Lessons are short, concise, direct and aimed at enhancing the child’s self-worth.

    Self-Education: A carefully prepared learning environment is set up to respond to the needs of children exposing them to materials and experiences that stimulate intelligence and promote physical and psychological development.

    Didactic Materials: Simple learning tools are provided for the toddlers and gradually moving up to more complex materials. Each piece of equipment is specifically designed to provide the child with a clear-cut experience, and then gradually lead to more complicated tasks, working at their own pace.

    Specially designed environment: Maria Montessori came up with he concepts of child-sized furniture.  All learning materials are within the child's reach.  Classrooms are compromised of living plants and pets that the children care for.  Mixed age groups (typically 2-6 year olds) encourages older children to be role models for their younger counterparts (it also creates a context of security), Learners also remain under the care of a teacher over a longer period of time than in a traditional setting. 

    Teacher’s role:  Emphasis on learning rather than teaching.  Teachers prepare and maintain the classroom to ensure that everything needed is within the children’s reach.  They are consistently available to respond to a child's needs and guide them towards self-study, independence, and self-confidence.

     

    Preparation for Multicultural Perspectives

    As US schools are becoming more diverse, we need to have multiple ways of knowing, from multicultural perspectives in order to be culturally responsive, develop our cultural competence and critical consciousness (Broughton A., 2020).  The influences of race, ethniciy, geography and sociopolitical traditions may not be considered in conventional child psychological theories.  Unlike conventional theories, the NAEYC's position statement is inclusive of multi-ethnic perspectives, which provides a deeper context to what is known as child development. 42 

    The US Educations system needs to remember, and center the work of scholars of Black intellectual thoughts on early childhood link Oneida Cockrell, Lulu Sadler Craig, Amos N. Wilson, Gayle Cunningham, Beverly Tatum, Randy Story, Jean Monroe, Sarah Greene, Frances Brock Starms, Janice Hale-Benson, Jerlean E. Daniel, Maryann Cornish...and the list goes on.  Entering their names to honor their contributions to the field of education (Broughton A., 2020).  One such early childhood education expert is Brian L. Wright, Ph.D., whom has helped us understand and identify the promise, potential, and possibilities of black boys pre K- 12. 

    Brian L. Wright, Ph.D.

    Dr. Brian L. Wright is a Program Coordinator of Early Childhood Education in the Department of Instruction and Curriculum Leadership in the College of Education and Coordinator of the Middle School Cohort of the African American Male Academy at the University of Memphis.  Dr. Wrights research examines the role of racial and ethnic identity in African-­American boys/males in urban schools pre K-12. Dr. Wright’s current research examining quality Early Childhood Education Programs for all children, but especially those children living in poverty, Culturally Responsive and Responsible School Readiness for African American boys (preschool and kindergarten), Literacy and African American males, African American and Latino males as Early Childhood Teachers, and Teacher Identity Development. Drawing from the wealth of experience in early childhood education, Wright presents an asset- and strengths-based view of educating Black boys ages pre K-12. 43
