Piaget’s Theory A framework to organize and interpret information.
© 2006 The McGraw-Hill Companies, Inc. All rights reserved. Santrock, Educational Psychology, Second Edition, Classroom Update Piaget’s Theory Schema Assimilation Accommodation Organization Equilibration A framework to organize and interpret information. The ability to incorporate new knowledge into existing knowledge. The ability to adjust schemas to the environment. Grouping isolated behaviors into a higher order. A shift, a resolution of conflict to reach a balance.

Basic Concepts in Piaget’s Theory
© 2006 The McGraw-Hill Companies, Inc. All rights reserved. Santrock, Educational Psychology, Second Edition, Classroom Update Basic Concepts in Piaget’s Theory Children actively construct their own cognitive world through: Organization Adaptation Assimilation Accommodation

© 2006 The McGraw-Hill Companies, Inc. All rights reserved. Santrock, Educational Psychology, Second Edition, Classroom Update Organization The mind’s grouping of isolated behaviors and thoughts into a higher-order system. It occurs both within and across stages of development.

Examples of Organization
© 2006 The McGraw-Hill Companies, Inc. All rights reserved. Santrock, Educational Psychology, Second Edition, Classroom Update Examples of Organization Two systems that humans use: Mathematical notation systems Language systems We organize ideas. For example, sorority and fraternity belong to the category social groups. Schemas for and web-browsing get organized into higher order systems (e.g. computer skills).

Two Processes in Adaptation

Accommodation Adjustment to new information involves changing old schemas. When you came to college you had to accommodate your schemas for learning.

Piaget’s Four Stages Cognition unfolds in a sequence of four stages.
© 2006 The McGraw-Hill Companies, Inc. All rights reserved. Santrock, Educational Psychology, Second Edition, Classroom Update Piaget’s Four Stages Cognition unfolds in a sequence of four stages. Each is age-related and distinctive. Each stage is discontinuous from and more advanced than the previous.

Piaget’s Sensorimotor Stage

If it’s in my hand, it’s mine. If I can take it from you, it’s mine. If I had it a little while ago, it’s mine. If it’s mine, it must never appear to be yours in any way.

Pre-operational stage (2-7 years)
© 2006 The McGraw-Hill Companies, Inc. All rights reserved. Santrock, Educational Psychology, Second Edition, Classroom Update Pre-operational stage (2-7 years) Two substages of the pre-operational period are: Symbolic function: 2-4 Years Intuitive thought: 4-7 Years

Piaget’s Preoperational Stage Symbolic Function Substage
© 2006 The McGraw-Hill Companies, Inc. All rights reserved. Santrock, Educational Psychology, Second Edition, Classroom Update Piaget’s Preoperational Stage Symbolic Function Substage Symbolic Thought: ability to represent mentally an object that is not present (drawing, pretend play, language). Limitations: Egocentrism: The inability to distinguish between one’s own perspective and someone else’s perspective. Animism: The belief that inanimate objects have “lifelike” qualities and are capable of action.

Piaget’s Preoperational Stage Intuitive Thought Substage
© 2006 The McGraw-Hill Companies, Inc. All rights reserved. Santrock, Educational Psychology, Second Edition, Classroom Update Piaget’s Preoperational Stage Intuitive Thought Substage Intuitive Thought rather than logical thinking (ask lots of questions). Centration: Focuses on one characteristic to the exclusion of others. Lack of Conservation ability —doesn’t understand that quantities remain the same, even when the matter has undergone a transformation. Lack of Classification: inability to classify objects according to only one characteristic

© 2006 The McGraw-Hill Companies, Inc. All rights reserved. Santrock, Educational Psychology, Second Edition, Classroom Update What is conservation? Conservation means understanding that a quantity is the same even when it undergoes qualitative changes. If you pour limeade from a beaker into a disk, the amount of liquid is the same. Does one look like it has more?

Piaget’s Concrete Operational Stage (7-11 years)
© 2006 The McGraw-Hill Companies, Inc. All rights reserved. Santrock, Educational Psychology, Second Edition, Classroom Update Piaget’s Concrete Operational Stage (7-11 years) Logical reasoning replaces intuitive reasoning, but only in concrete situations. Conservation: The idea that some characteristics of an object stays the same even though the object might change in appearance. Classification: Coordinate several characteristics rather than focus on a single property of an object. Seriation: Order stimuli along some quantitative dimension. Transitivity: Combine relations to understand certain conclusions. “ If J is taller than M, and M is taller than S, who is taller – J or S?”

Hierarchical Classification
© 2006 The McGraw-Hill Companies, Inc. All rights reserved. Santrock, Educational Psychology, Second Edition, Classroom Update Hierarchical Classification When shown a family tree of four generations, the concrete operational child can classify the members vertically, horizontally, and obliquely (up, down, and across).

Conservation of Length
© 2006 The McGraw-Hill Companies, Inc. All rights reserved. Santrock, Educational Psychology, Second Edition, Classroom Update Conservation of Length Is one of these lines longer or are they they same? What would the pre-operational child say?

© 2006 The McGraw-Hill Companies, Inc. All rights reserved. Santrock, Educational Psychology, Second Edition, Classroom Update Conservation of Length The preoperational child would say the one on the top is longer. Pre-operational children base their concepts on perception, not logic.

© 2006 The McGraw-Hill Companies, Inc. All rights reserved. Santrock, Educational Psychology, Second Edition, Classroom Update Conservation of Length Are all of these lines the same length? Is one longer? What would the pre-operational child say?

© 2006 The McGraw-Hill Companies, Inc. All rights reserved. Santrock, Educational Psychology, Second Edition, Classroom Update Conservation of Length Preoperational children are tricked by perception. The think the one “out front” is longer.

Conservation of Area Which side has more green?
© 2006 The McGraw-Hill Companies, Inc. All rights reserved. Santrock, Educational Psychology, Second Edition, Classroom Update Conservation of Area Which side has more green?

© 2006 The McGraw-Hill Companies, Inc. All rights reserved. Santrock, Educational Psychology, Second Edition, Classroom Update Both have the same area of green. Preoperational children rely on perception and think the one on the right has more.

© 2006 The McGraw-Hill Companies, Inc. All rights reserved. Santrock, Educational Psychology, Second Edition, Classroom Update Concrete operational children can conserve. They understand that the amount of area is the same in spite of qualitative change (i.e., rearranging).

Conservation of Number

Conservation of Number
© 2006 The McGraw-Hill Companies, Inc. All rights reserved. Santrock, Educational Psychology, Second Edition, Classroom Update Conservation of Number Pre-operational children think the row on the bottom has more. Later they develop one-to-one correspondence. They understand there is one for this one, one for that one, and one for that one, etc.

Piaget’s Formal Operational Stage
© 2006 The McGraw-Hill Companies, Inc. All rights reserved. Santrock, Educational Psychology, Second Edition, Classroom Update Piaget’s Formal Operational Stage Abstract reasoning: think in abstract, idealistic, and logical ways Hypothetical-deductive reasoning: The ability to develop hypotheses about ways to solve problems and systematically reach a conclusion Adolescent egocentrism: Heightened self-consciousness and a sense of personal uniqueness

Features of Formal Operations
© 2006 The McGraw-Hill Companies, Inc. All rights reserved. Santrock, Educational Psychology, Second Edition, Classroom Update Features of Formal Operations Adolescent egocentrism: Imaginary audience: desire to be on-stage, noticed, and visible Personal fable: sense of personal uniqueness and indestructibility “No one has ever felt like this before!” “I drive better when I’m drunk!”

Piaget’s Cognitive Constructivism Theory into Practice
© 2006 The McGraw-Hill Companies, Inc. All rights reserved. Santrock, Educational Psychology, Second Edition, Classroom Update Piaget’s Cognitive Constructivism Theory into Practice Jennifer, James, and several of their classmates are playing hide-and-go-seek during indoor recess one rainy day. Jennifer carefully conceals her entire body behind Mrs. Johnson’s long smock. In contrast, James hides only his upper body behind a jacket hanging on a hook. He giggles, sure that his classmates will never see him. A: Pre-operational. He is suffering from pre-operational egocentrism. He believes that if he cannot see his classmates, they cannot see him either. Q: Based on the information given above, at which of Piaget’s stages of cognitive development is James most likely operating? Explain.

© 2006 The McGraw-Hill Companies, Inc. All rights reserved. Santrock, Educational Psychology, Second Edition, Classroom Update Piaget’s Cognitive Constructivism Theory into Practice Mr. Jackson has a sand table in his Kindergarten classroom. He provides his students with many containers of different sizes and shapes to play with in the sand. He watches as his students carefully pour sand from one container to another. One little girl, Michelle, seems amazed when she pours sand back and forth between two containers. The sand always fills up one container and only half-fills the other, yet the containers are the same height. A: Conservation. She is learning that height and width of the container both contribute to how full the container becomes with the same amount of sand. Q: Based on the information given above, what skill is Michelle most likely developing? Explain.

Santrock, Educational Psychology, Second Edition, Classroom Update Piaget’s Cognitive Constructivism Theory into Practice Mr. Welby teaches high school English. He always asks his students to find the symbolism in the great works of literature he assigns. Some students do this with relative ease. For others it is a real struggle. Many are only able to parrot back what he has told them in class. A1: Formal operational. They can understand the symbolism in literature due to their ability to think abstractly. A2: Concrete operational. They are able to remember what Mr. Welby tells them, but cannot think abstractly enough to understand the symbolism. Q.1: At which of Piaget’s stages are those who understand the symbolism in literature likely operating? Q.2: At which of Piaget’s stages are those who cannot understand the symbolism in literature likely operating?

Santrock, Educational Psychology, Second Edition, Classroom Update Piaget’s Cognitive Constructivism Theory into Practice Marsha refuses to go to school one morning because she is having a “bad hair day” and is certain that everyone will stare at her all day. Her mother assures her that she looks just fine. However, Marsha races back to the bathroom to attempt to fix her “awful hair”. A: Marsha is suffering from adolescent egocentrism. She is very self-conscious and believes that others will be just as interested in, and hence as critical of, her hair as she is. Q: What would Elkind say is happening here?
