2. Biography
“The Mozart of Psychology”
Lev Vygotsky 1896-1934
A Russian psychologist and educator
Born 1896 (same year as Piaget)
Jewish middle class family
Privately tutored
Graduated Moscow State University 1917
Taught literature and psychology for seven years
Post-World War revolutionary Russia
3. Over 100 books and articles
Theory not known among English-speaking
educators until 1960s when works were translated
Few scholarly works published during his lifetime
Shortly after his death Vygotsky’s work was
banned in the Soviet Union for more than twenty
years
He died on June 10, 1934 at 37 after long battle
with TB
He is considered a influential thinker in
psychology, and much of his work is still
discovered and explored today
4. Vygotsky Theory is that social interaction plays a
very important in cognitive development
Did not focus on the individual child but on the
child as a product of social interaction, especially
with adults
Focus on dynamic interactions rather than child
by himself
People thinking differs dramatically between
cultures because different cultures stress different
things
5. Some terms
ontogenetic development
development of the individual over his or her lifetime.
microgenetic development
changes that occur over relatively brief periods of
time, in seconds, minutes, or days, as opposed to larger-
scale changes, as conventionally studied in ontogenetic
development.
phylogenetic development
development over evolutionary time.
sociohistorical development
changes that have occurred in one’s culture and the
values, norms, and technologies such a history has
generated.
6. cognitive growth occurs in a sociocultural
context that influences the form it takes,
and
many of a child’s most noteworthy
cognitive skills evolve from social
interactions with parents, teachers, and
other more competent associates.
7. Two main principles
The More Knowledgeable Other (MKO) -
anyone who has better understanding or higher
ability level than the learner
Normally thought of as being a teacher, trainer,
or older, adult, but MKO could also peers, a
younger person, even computers
ZPD= Zone of Proximal Development
9. ZPD= Difference between what child can accomplish
alone and s/he can accomplish with the guidance of
another
The range of tasks a child cannot yet do on their own,
but can do with the help of others is known as the Zone
of Proximal Development (ZPD)
Children can perform more challenging tasks when
assisted
Challenging tasks promote maximum cognitive growth
Actual developmental level – Extent to which the child
can perform tasks independently
Level of potential development – Extent to which the
child can perform tasks with assistance
10. To help a child move through the ZPD, assistance is
provided by scaffolding
Zone of Proximal Beyond reach Development is a
distance between at present the actual developmental
level determined by individual problem solving and the
level of development ZPD as determined through
problem solving under guidance or in collaboration
with more capable peers
Child’s current achievement Within the ZPD are those
skills or tasks too difficult for a child to master on his
or her own; but that can be done with guidance and
encouragement from a knowledgeable person
11. Two features of ZPD
I. Scaffolding
Appropriate assistance given by the teacher to assist the
learner accomplish a task
Requires that an instructor shows example how to solve
a problem, while controlling the learning environment
so that students can take things step by step expanding
their knowledge without excessive frustration
II. Reciprocal Teaching
A highly successful teaching method, it provides an
environment of open dialogue between student and
teacher which goes beyond a simple question and
answer session.
12. Scaffolding
Assistance provided by more competent peers
or adults to enable the task to be done
successfully
Scaffolded instruction allows the learner to
move through the ZPD
Modelling; feedback; instruction; questioning;
encouragement; task structuring; chunking;
breaking the problem down
Scaffolding is gradually withdrawn
13. Four basic principles of Vygotsky
1) Children construct their knowledge
2) Development cannot be separated from its
social context
3) Learning is mediated
4) Language plays a central role in mental
development
14. Two types of mental functions
1. Lower Mental Function - Are those with
which we are born, are the natural functions
and are genetically determined.
2. Higher Mental Function - Are acquired and
developed through social interaction.
15. Teaching implications
Students need many opportunities to
learn with a teacher and with more-
skilled peers
Work within the zone of proximal
development – Establish a level of
difficulty
Challenging, but not too difficult
May mean differentiating learning
experiences – Evaluate independent
performance
16. Provide scaffolding – Scaffolded instruction –
Assisted performance
Teacher or more capable peer – Cooperative
learning
Incorporate language and self-instruction in
teaching – Model language use when
completing tasks – ‘Think’ out loud
Regularly monitor and assess students’
independent performance

18. Stage Characteristics
Thinking in
unordered
heaps
•Preschool stage of development
•Beginnings of conceptual thought
•Children use trial and error
•Children use problem solving techniques
•Three sub phases
Thinking in
complex stage
•Children begin to make connections between
objects,
•but not in a consistent manner
•Five sub -phases
Thinking in
concepts stage
•Children are able to think in more abstract
concepts and make associations
•Cannot see two associations simultaneously
Thinking in true
concepts stage
•Mature thinking
•Children can manipulate a number of abstract
concepts
19. Conclusion
Socio-cultural theory considers learning as a
semiotic process where participation in
socially mediated activities is essential.
Social interaction emphasized that effective
learning happens through participation in
social activities, making the social context of
learning crucial.
Vygotsky theory was important in education
since these works provide tools for the
development of individuals learning.
20. Vygotsky’s Theory of Language and
Thought
Vygotsky agreed with Piaget that the child’s earliest thinking is
prelinguistic
early language often reflects what the child already knows
thought and language eventually merge and that many of the
nonsocial utterances that Piaget called “egocentric” actually
illustrate the transition from prelinguistic to verbal reasoning
preschool children’s self-directed monologues occur more often
in some contexts than in others, specifically as they attempt to
solve problems or achieve important goals
this nonsocial speech increased substantially whenever these
young problem solvers encountered obstacles in pursuing their
objectives.
21. nonsocial speech is not egocentric but
communicative; it is a “speech for self,” or
private speech, that helps young children to
plan strategies and regulate their behavior so
that they are more likely to accomplish their
goals
language play a critical role in cognitive
development by making children more
organized and efficient problem solvers
22. Primitive Stage
babies cry and babble
These are examples of the primitive stage of
language development.
The sounds produced serve no real purpose except
to produce the sound and experiment with our new
capability.
Just as a baby laid on his belly may make crawling
motions yet not crawl, the baby may also make
sounds without producing speech.
As the baby does not produce speech, there is also
not verbal thought, or internal monologue.
23. This does not mean the baby does not think, it
only means that the child has not yet internalized
his speech.
The verbalization performed at this stage serve
no purpose except to practice sound.
There is no reason for the child to internalize
during this stage.
24. Naive Stage
As the child begins to speak, he learns how to say words
far before he learns their meaning and function
An example of this manifestation is “ball”
To the child this one word can mean a variety of things
(“where is my ball”, “give me the ball”, etc.)
To an adult with an established knowledge of language,
this word refers to a child’s toy, to a child though it can
have various meanings
As the child develops and gains understanding of new
words, he begins to produce naïve sentences like “where
ball” and “where is the ball”
25. The child uses these structures without any
understanding of how to put a sentence together
or why the words must go in that order.
He only knows that when the words are said in
a certain way, others understand his meaning.
Understanding of word order comes about
before the child learns the logic of how the
words fit in that order.
26. External Stage
child begins to use external objects to represent
words
characterized by the child using flash cards,
objects, or fingers when counting
Rhyming is also used during this stage to improve
memory and sound recognition
Another interesting event is the beginning of
egocentric speech
The child will talk to himself when there is no one
else around and also during play with others
This is the child’s verbalization of thought
27. Ingrowth Stage
As the child’s egocentric speech turns inward,
he enters the final stage
He uses the skills he has acquired to perform
logical tasks internally
Rather than counting aloud, he will count “in
his head” using part of his short term memory
This much faster than verbalizing each thought
and just as his initial speech developed with
practice, the more internalized thought and logic
is used, the better the child can perform.
28. Language Development
particularly interested in the role of language in
cognitive development
language is vital to human interactions,
believed that language was the most important
tool that human could utilize
Language, especially in the realm of
collaborative dialogue, is the way the more
knowledgeable other communications important
information to a child
believed that there are three forms of language
29. Social Speech –referred to as the external
communication that people use to talk with other people,
and he believed that this form of language was typical in
children from the age of two.
Private Speech –referred to as the internal
communication that a person directs to themselves. It
serves an intellectual function, and it is typical in children
from the age of three.
Silent Inner Speech –happens when private speech
diminishes in its audibility until it become a self-
regulating function. believed this was typical in children
from the age of seven.
30. focus on language as a part of cognitive development
was based on the idea that at the beginning of a child’s
life, language and thought begin as separate systems
within a child’s brain
Believed these two systems would merge in the child at
around the age of three, and the two systems would
become interdependent
As the two systems become interdependent, a child’s
communication can be internalized to become private
speech to the self, and this internalization of language is
an important component to a child’s cognitive
development.
31. private speech was an important mile marker
in a child’s cognitive development because it’s
the moment in a child’s development where
thoughts become connected with words, and a
child begins exhibiting verbal thinking.
Whereas social interaction is an important part
of cognitive development as a child learns
from a more knowledgeable other, private
speech allows a child to begin the
collaborative process of learning with
themselves.
