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
