sets of similar actions or thoughts that they uses repeatedly in response to the environment

an organized and integrated system of logical thought processes

responding (either physically or mentally) to a new event in a way that is consistent with an existing scheme.

Process of responding to a new event by either modifying an existing scheme or forming a new one.

State of being able to address new events using existing schemes

State of being unable to
address new events with existing schemes

Movement from equilibrium to disequilibrium and back to equilibrium; a process that promotes the development of increasingly complex forms of thought and knowledge.

cognitive development

Systematic changes in reasoning, concepts, memory, language, and intellectual skills

Piaget

Stages of Cognitive Development

Concrete Stage

Sensorimotor stage

Formal Operation Stage

Begins at birth

Preoperational Stage

about 6 or 7

about 11 or 12

schemes are largely based on behaviors and perceptions

in the being, children can't think about thigs that are not directly in front of them

they focus on what they are doing and seeing in the moment

e.g.

trial-and error experimentation

object permanence

symbolic thought

Goal-directed behavior

about 2

because of symbolic abilities, thinking and talking about things beyond immediate experiences is posible

e.g.

Language

Extensive pretend play

Intuitive thought

Adult-like logic appears but is limited to thoughts about concrete, real life situations

e.g.

mine vs. yours perspective

Class inclusion

Classifying objects into 2 or more groups

Consercation

amount stays the same despite appearances

logical reasoning processes are applied to abstract ideas and concrete situations. advanced reasoning in science and math

e.g.

Ability to draw conclusions about situations that can't be directly perceived

Separation and control of variables

Understanding of fractions, percentages, decimals, and ratios

Idealism

Ability to envision alternatives to social practices

In Vygosky's theory, a process through wich adults help childern make culturaly appropriate sense of experiences

e.g. attaching lables to obgects

e.g. explain the nature of certain phenomena

Concept, symbol, strategy, or other culturally constructed mechanism that helps people think more effectively.

talking to oneself as a way of guiding oneself through a task

"talking" to oneself mentally rather than aloud as a way of guiding oneself through a task

In Vygotsky's theory the gradual evolution of external social activities into internal mental activities

Gradual adoption of (and adaptation of) other people's ways of thinking and behaving for one's own purposes.

Range of tasks that one can't yet preform independently but can preform with the help and guidance of others

Play in which children take on specific roles and act out a scenario of imaginary events

discussion between an adult and a child in which the adult helps the child make sense of an event they have mutually experienced

support mechanism, provide by a more competent individual, that helps a child successfully preform a task within his or her zone of proximal development

the child's active immersion in cultural activities, typically with considerable direction form an adult or other individual with relevant expertise; childern are given increasing responsibility and independence as they gain experience and proficiency

mentorships in which a novice works intensively with an expert to learn how to accomplish complex task in a particular domain

Instructional activity similar to one that a child might eventually encounter in the outside world

Mentorship in which an expert and a novice work together on a challenging task and the expert suggests ways to think about the task.

the ability to retrieve, interpret, evaluate, create, and communicate information from interactive computer resources and technologies

theoretical perspective that focuses on how people independently construct meaning from their experiences

Theoretical perspective that focuses on people's collective efforts to impose meaning on the world.

Approach to teaching reading comprehension in which students take turns asking teacher-like questions of their classmates

Realization that objects continue to exist even when they are out of sight

Ability to mentally represent and think about external objects and events

Inability of a child in Piaget's preoperational stage TV situations from another person's perspective

Realization that if nothing is added or taken away an amount stays the same regardless of alteration in shape or arrangement

Recognition that an object simultaneously belongs to a particular category into one of its subcategories

Theoretical perspective that combines elements of Piaget's theory with more contemporary research findings and suggest that development and specific content domains is often stage like in nature

Component of memory that enables people to actively think about and process a small amount of information

Integrated networks of conception and cognitive process that forms the bias for much of one's thinking, reasoning, and learning in a specific content domain

Situation in which one encounters and has to wrestle with ideas and viewpoints from others different from one's own

Theoretical perspective proposing that Learners construct a body of knowledge and beliefs, rather than absorbing information exactly as it is received

Procedure in which an adult probes a child's reasoning about a task or problem, tailing questions to what the child has previously said or done in the interview

About an anticipated outcome

Current Perspectives

Research supports sequence

Research does not support ages

infants show object permanence at 2 1/2 months

Preschoolers aren't always egocentric and often demonstrate conservation and class inclusion

some elementary students exhibit abstract reasoning

some high-school students never develop abstract reasoning

Knowledge, experience, and culture affect reasoning abilities

conversation my be taught

children age 4 or 5 exhibit conservation after experiencing it

prior knowledge affects formal operations

education and culture affect cognitive development

cognitive development may not be universally stage-like

Key Ideas in Neo-Piagetian Theories

Cognitive development is constrained by information processing mechanisms

Working memory

Children acquire new knowledge through unintentional & intentional learning processes

Children acquire cognitive structures that affect thinking in content domains

central conceptual structures

Cognitive development depends on features of and changes in the brain

Cognitive development is enabled by development of executive function

Development in content domains may sometimes be characterized as a series of stages

applying the Ideas

Keep Piaget’s stages in mind, but don’t take them too literally

Present situations and ideas that children cannot easily explain using existing knowledge & beliefs

Explore children’s reasoning, problem-solving with different activities & questions

Use familiar content and tasks when asking children to reason in sophisticated ways

Provide opportunities for children to play and experiment

Plan group activities in which young people share their beliefs and perspectives

Vygotsky

Key Ideas in Vygotsky’s Theory

Every culture passes along physical and cognitive tools

Some cognitive processes are seen in many species; others are unique to humans

Adults convey cultural interpretations through informal interactions & formal schooling

Children acquire tools in their own idiosyncratic manner

mediation

appropriation

Complex mental processes begin as social activities & evolve into mental activities (internalization)

Play allows children to stretch themselves cognitively

Thought & language become interdependent

self-talk becomes inner speech

Challenging tasks promote cognitive growth

Children can perform more challenging tasks when assisted

zone of proximal development

Current Perspectives Related to Vygotsky’s Theory

Elaboration of the idea that meaning is socially constructed

Introduction of the concept of scaffolding

mediated learning experience

support for challenging tasks

Elaboration of ways in which children participate in adult activities

Recognition of how children teach other children

cognitive apprenticeship

guided participation

Applying the Ideas

Present challenging tasks

Assess children’s abilities under a variety of work conditions

Help children internalize cognitive strategies

Provide opportunities to engage in authentic activities

Help children acquire cognitive tools

Encourage and scaffold play

use group activities like reciprocal teaching

provide reminders of what to do

provide sufficient scaffolding

help children develop strategies to scaffold themselves

look for examples of different types of play:

exploratory with objects

group play

imaginary play with symbolic objects

role taking

Comparing Perspectives

constructive

Readiness

Social

Children can accommodate only when they can also assimilate the objects

Individual

An ever-changing zone of proximal development

They can only if they have constructed the relevant logical operations

Challenge

Children develop more sophisticated thought processes when they encounter phenomena that create disequilibrium

Children benefit most from tasks that they can preform only with assistance

social interaction

Other present information and arguments that create disequilibrium and foster perspective taking

Children internalize the processes they use with others until, ultimately, they can use them independently

logical adult-like reasoning is not developed

Developmental schemes are independent, requiring little guidance

Interaction with peers is more valuable

Cognitive development is independent of language

Culture is not important in determining thinking styles

lower vs. higher functions

Activities are facilitated & interpreted by more competent individual

Interaction with advanced individuals is more valuable

Language is essential for cognitive development

Culture is critical in determining thinking styles

Take-home Messages

Vygotsky

Similarities

Piaget

Differences

probably underestimated capabilities of children

probably overestimated the capabilities of adolescents

children are active, motivated learners who construct understanding based on experience

humans differ from other species in their acquisition of complex mental processes, which are largely the legacy of cultural heritage

constructive processes, readiness, challenge, social interaction

role of language; relative value of free exploration versus structured, guided activities; relative importance of interactions with peers versus adults; influence of culture
