What Is Piaget’s Theory of Development?
Jean Piaget proposed four stages of cognitive development. These stages help teachers assess and best serve students in the classroom. That is, if we can discern that a student is significantly over or under-developed with regard to their particular phase of development, we can seek out support for that child. We can also work with children who are in a transitional phase from one stage to the next. When we understand what their next stage is supposed to entail, we can help them master those skills or abilities.
The four stages are:
Sensorimotor – 18-24 months
Preoperational – 18 months to 2 years
Concrete Operational – 7 years to age 11
Formal Operational – approximately age 11 through the rest of life
One key part of Piaget's theory of cognitive development is his emphasis on adaptation. That is, he saw that young people did not yet have the tools that were available to fully developed adults. Rather, children undergo a lengthy process in which they find moments of disequilibrium with their world but then apply old lessons, schema to Piaget, to assimilate the new information or situation.
Terminology
- Schema
Piaget's cognitive theory posits schemas as the core of one's ability to build mental models of the world. As we develop, our schemas become more intricate, detailed, and numerous. We have schemas to help us navigate our lives. For instance, one's schema for commuting to work would involve things like starting and driving a car, boarding a train, navigating a route, and arriving at the destination. Within each of these basic stages we have sub-schema such as shifting gears, purchasing a ticket, reading a map, using alternate routes, etc.
In a developmental context, we see that these schema begin as rudimentary and simple ideas that largely concern basic behaviors, shape, color, and perhaps smell. After approximately 18 months, we begin to see how various items work together to form complex systems, etc.
- Assimilation
This is a part of Piaget's all-important notion of adaptation. When we assimilate, we take new information, objects, or situations and apply them to pre-existing schema to understand them. For instance, if one knows French but then finds themselves in Spain, they might see that Spanish has many similarities to French. Thus, they assimilate the two in order to navigate the new culture. We use assimilation all the time when we visit new restaurants, drive new cars, or even meet new people.
- Accommodation
Accommodation is another vital part of adaptation. In the example above, a traveler to Spain might rely on their knowledge of the French language to navigate the new culture. However, while French and Spanish have many things in common, they will still have to adapt their schema so that they can learn the nuances of Spanish. Similarly, game players change their strategies to meet the unique demands of a new opponent or game.
- Equilibrium
In Piaget's developmental theory, the need for equilibrium is what drives cognitive development. That is, when a person encounters a new situation that cannot be easily assimilated, disequilibrium occurs. This triggers frustration and other negative emotions until the new information can be accommodated/assimilated. Once a person adapts to the new situation, growth and development occur.
What Are the Four Stages?
Sensorimotor Stage
This first stage of development begins at birth and continues until 18-24 months. This pre-linguistic stage involves adaptation to the world of objects and simple motor skills. During the early months of this stage, infants are unaware that objects continue to exist when they are out of sight. Thus, a key moment of equilibrium is when they gain object permanence. From this point, children understand that a toy or other object will remain in a chest, for example.
At the same time, children must learn to navigate their environment by rolling over, crawling, and finally walking. At about the same time that they are beginning to walk, children expand on the abstract lessons of object permanence and begin to represent objects and ideas with language. Once a child can understand that food is still in the cupboard, she can ask for it. Thus begins the next stage.
Preoperational Stage
At approximately age 18 months to two years, a child enters the Preoperational Stage, which lasts until around age seven. This stage is characterized by the increasing ability to use language. Verbal skills progress at what may seem like a rapid pace. Imagination and abstract thinking progress at a fast clip as well, and their expressions become more and more mature as the need for equilibrium with adults and siblings drives increasing adaptation.
Growing children in this stage will notably lack strong logic skills. They might struggle with abstractions such as time, distance, and how to compare and contrast items. It is also difficult for children in this stage to solve problems mentally, and they must still rely on physical representations. Further, they will be incapable of seeing things through the eyes of another. Thus, younger children might often seem to behave cruelly towards their peers, animals, and even adults. This egocentrism does not last forever, thankfully.
Concrete Operational Stage
During this stage, which begins around age seven and lasts until age 11, children begin to implement operational thought. They can represent operations in their minds and solve problems for items or situations that are far removed from their physical space. Another important cognitive ability is what Piaget termed conservation. This is the ability to understand that an object might retain its quantitative values (mass, weight, etc.) even though it has changed its appearance. Thus, they can now grasp the idea that the same volume of water fills both a tall, skinny container and a short, squat cup.
Children also begin to loosen their bonds of egocentrism. They begin to see that their thoughts and feelings are their own and are not necessarily shared by others. They can also begin to see how others might experience an event and are more aware of external events and situations that don't necessarily involve them.
Formal Operational Stage
This is the final stage of Piaget's theory of cognitive development, and it lasts from approximately age 11 through the rest of life. This stage is characterized by the ability to think abstractly, create hypothetical situations, and then test those hypotheses. We begin to see how seemingly disparate concepts or objects relate to one another, and the world becomes one of increasing possibility.
Though this is Piaget's final stage of cognitive development, human cognition continues to mature and grow. That is because Piaget saw that, by this point in life, people generally have the core abilities they need to navigate the world. From age 11 onward, people continue to respond to the need for equilibrium and have the ability to adapt and grow.
How Can Teachers Use This?
Developmental theories are a large part of what drives a teacher's approach to the classroom. In fact, every teacher-prep program requires courses on childhood development so that teachers have an understanding of where their kids are or should be from a psychological view. Most of these theories focus on our emotional and social lives. One of the most popular theories of human development, the Ericksonian model, addresses cognition and information processing almost as an afterthought.
What makes Piaget's model stand out in the field is its specific attention to cognitive development. It focuses on how human beings process information and how that processing changes throughout a lifetime. In particular, his theory focuses on the mechanisms that help us adapt and learn new concepts or skills.
In the classroom, teachers can apply Piaget's notions of assimilation and accommodation when introducing new material. They can help students approach a new idea through the lens of what they have already learned. When they can achieve what Piaget called equilibrium, they can then move forward to again advance their knowledge.
One key element for teachers to be cognizant of is their students' particular age and relative development. Preschool teachers can look at Piaget's Sensorimotor Stage and help children learn to recognize simple shapes and colors.
Teachers who have classrooms for Preschoolers through approximately grade 2 should take a close look at the Preoperational Stage. It's important to note that children in this stage will not have a grasp of logic. Rather, their thoughts and behaviors will be egocentric and more intuitive. Teachers can thus put their lessons and student interactions in this context. Later in the stage, educators can integrate more abstract thinking, non-egocentric concepts, and advanced language skills. Some students will be able to adapt more quickly to the increasing complexity and can be encouraged to model their adaptive methods for their peers.
Teachers can approach the two later stages, Concrete Operational and Formal Operational, in much the same way. They can assess where their students are within the age-appropriate stage and then help them transition to the next. For older students in the final stage, teachers can build on the basic tools of adaptation and build lesson plans that ease the acquisition of new knowledge and skills.
Criticism
No theory is without its criticisms. Piaget's theory of cognitive development is no stranger to detractors who find that it does not hold up to professional scrutiny from researchers or pure theoreticians. In particular, Piaget's theory is attacked based on his research, sample bias, and a seeming underestimation of children's abilities.
Many point to the fact that Piaget based his work on a very small sample size that included his own children and their peers. Not only is this a very small group from which little data could expect to be culled, but the children involved were also all from privileged backgrounds. Further, since Piaget didn't clearly define his variables, it is nearly impossible to replicate his study. For any study to be considered valid, it must be subject to easy replication.
The theory is also attacked because it allegedly underestimates how children actually learn. Where Piaget posited that children in the Preoperational Stage were egocentric and incapable of understanding the experiences of others, subsequent research has contradicted this. In fact, research has found that children as young as three are capable of non-egocentric thoughts and behaviors.
Piaget's concept has had a substantial impact on the concept along with the approach of education and learning. It has aided to develop a view where the prime focus jumps on the recommendation of developmentally ideal education. This defines an instructional with settings, educational program, items and likewise standard that are consistent with trainee's physical and also cognitive abilities in addition to their social and psychological demands.
Acceptance of particular differences in developmental growth. Piaget's concept insists that kids go through just the same developmental stages, nonetheless they do so at various prices. As a result of this, teachers need to make a distinct effort to prepare classroom tasks for individuals and also groups of children as opposed to for the entire course group.
It is really important that the material of direction requires to be consistent with the establishing degree of the learner. The teachers key function is the aid of understanding by offering numerous experiences for the students. "Exploration Discovering" permits opportunities for pupils to discover in addition to experiment, while urging new understandings. Opportunities that enable students of different cognitive degrees to team up usually help desire much less fully grown trainees to progress to a greater understanding of the material.
Some keynotes consist of: Using concrete props as well as visual help, such as versions and/or time lines Advertise discovering by using familiar examples to clarify complex ideas, such as a tale trouble in mathematics Offer students the possibilities to classify & team information, utilize describes & hierarchies to advertise adaptation of new information with formerly discovered knowledge.6.
There are numerous functional applications that can be made from this theory. By utilizing them in our training, we can with any luck instruct trainees in an approach that will certainly help them be just one of the most efficient trainees. Sensorimotor Duration: Tasks for Infants as well as ToddlersThe term "sensorimotor" originates from the child understanding their world generally via their detects for their initial 2 years.
It focuses on the reflexes that the kid is birthed with such as sucking, getting to and also understanding. In this phase of growth the kid at some point establishes vital round reactions, which are tasks centered on the kid's body in addition to repeating in nature. Ultimately, kids develop the synchronization of different tasks and likewise the advancement of language.
Offer a plentiful stimulating environment-Allow the child to play with toys that squeal when pressed. (ex-spouse: rubber duck) At first when the youngster presses the toy, they will certainly be surprised by the sound along with why it took place. Nonetheless, after time the kid will definitely acknowledge that by squeezing the toy they are the one developing the audio.
Playing peek-a-boo is an additional fantastic instance of a satisfying task for kids around this age. Preoperational Duration: Jobs for Toddlers as well as additionally Really very early Young people This phase holds when kids are concerning 2 to 7 years old.
"The Student and the Teacher" is an excellent book on how to apply Piaget's stages of development in the classroom. It provides a simple yet powerful approach that helps teachers explain basic concepts with great clarity. While there is plenty of information in this book, it can be difficult to determine which stage the material should be presented in.
The first stage of Piaget's development involves a student taking the initiative to do some investigation and learning. During this stage, students are encouraged to take on the role of the detective as they begin to work out some problems related to the concepts that they are being taught. At this stage, students will be introduced to the concept of problem solving through a variety of problem solving approaches. This stage is usually the first one to last all semester.
The second stage of Piaget's development deals with presenting the findings from the first stage. In the second stage, students are expected to write down their findings. In addition to that, they are also expected to formulate some solutions for the problems that they have found. This stage may require some brainstorming to come up with some answers that are relevant to the subject. This stage is also usually the last one to last all semester.
The third stage deals with presenting the solutions that they have come up with to their problems. Students are also required to create some diagrams and graphs to show the relationships among their findings. In addition, they are also expected to demonstrate the accuracy of their findings using drawings, graphs, or charts.
The fourth stage deals with analyzing their results. Students are also required to take a critical examination of the materials that they used in the process. They are also asked to present some possible reasons why their findings were wrong and to justify their reasoning.
The final stage deals with developing a plan of action for future research. The first stage is followed by a plan, which is used to present results that can be used in the second and third stages. Students then need to work with a teacher to create a final report, which contains a summary of all the information that was presented during these three stages. The plan is used to give students a good overview of the material that they learned during their studies.
Overall, this book on applying Piaget's stages of development is a very helpful guide for teachers to help their students understand the various stages of development. The chapters that deal with the first three stages are easy to read and understand. However, the fourth and fifth stages are more complicated because of the different types of methods that are used to develop the content that is used in the classroom.
Another important aspect that is worth mentioning is that the book makes it easy to follow the stages that are being presented in the lessons. Although the text is not entirely laid out, the author explains everything that is discussed in each step so that it can easily be followed. While the text is not very lengthy, it can be easy to follow and it does have diagrams that make it easy to follow.
The authors of the book also made it possible for the students to find the answer to their questions from the second step, and the final stage. Students are also able to print out the final report and use it for a grade.
In addition, applying Piaget's stages of development can be used by teachers to train their own students to use the concepts that are used in the text. Students should also remember that there are some additional activities that will help them understand the material that they learned.
Overall, applying Piaget's stages of development can be useful for students who want to learn how to use the different stages of development in the classroom. It is also helpful to teachers who want to enhance the learning process and make the lessons easier for their students.
How Piaget’s Philosophy & Work Has Helped
While much of Piaget's work has not been successful in holding up to subsequent research, it still holds value for psychologists and teachers alike. His theories are still taught as part of a standard course in Human Development and he retains relevance, not completely due to his scientific strengths, but because of his importance as a pioneer.
Piaget broke important new ground in the field of human development. If he is to be remembered for any one thing, it is his focus on children as distinct from adults. Before his work and writing, psychology largely saw children as small adults. Though his conclusions might not hold as much water today, Piaget was able to identify that children passed through developmental stages on their way to processing information as adults. Further, his work showed that parents, teachers, and other community members need to acknowledge this developmental process to produce high-functioning adults.
His methodology, while not without significant flaws, was also groundbreaking. That is because he conducted in-depth interviews with his subjects. Previous researchers had not attempted this, and now subjects are frequently asked to describe and analyze their own thinking.
