About Lev Vygotsky


Lev Vygotsky (1896-1934): Russian socialconstructivist psychologist
Main Concepts
 Higher
and lower mental functions
 Cognitive-Mediation Theory
 Zone of proximal development (ZPD)
Zone of proximal development




Definition: ‘…the distance between the actual developmental level
as determined through independent problem solving and the level of
potential development as determined through problem solving under
adult guidance or in collaboration with more capable peers’
(Vygotsky, 1978, p. 86)
Zone of Proximal Development describes the human development as
a s socially mediated activity.
Cognitive apprenticeship
Examples



Birdhouses and mom reading
Two 8 yr old pupils at the same actual level of knowledge: different
speed of assisted problem-solving: different ZPDs
There is no single point at which the child had developed the skill
but didn’t have it before.

ZPD: Summary








Development level is not a point but a range
From complete mastery of lower level skills and
knowledge to the upper limit
Actual – potential: in between is present
Zone is dynamic
Each knowledge domain has its own zone
Varies per person
Society and adult cooperate in creating tools for
development: More Capable Peer or Adult
Intermental to intramental
Scaffolding




Not Vygotsky’s term but his concept: dynamic,
adaptive support and adult mediation of child’s
learning
Term introduced by Jerome Bruner: "vicarious
consciousness"
Support just above the level of construction
Has to be within ZPD
Vygotsky: Social pretend play provided scaffolding
Co-construction of skills
ZPD in literature: 1
Hasse, Institutional creativity (2001)
 The two students - Alexander and Anni - are not on
the same level of ZPD.
 Different contexts and different expectations
 Role of the teacher: not just master the textbook,
but point the pathways for development (Fielding
model!)
Hasse suggests that the teacher also operates within the
ZPD and has own the zone of actual and a potential
development

Salomon , Cognitive Effects With and Of Computer
Technology (1990)
Effects of technology: cognitive residue
Effects with technology: can now do more
System child+adult more intelligent that each
separately: computer as a more capable peer or adult
But can the child grow cognitively? Yes, is there is a
mindful engagement:
Stretching abilities boundaries (=scaffolding)
 Skills internalization (intermental to intramental)

ZPD in literature: 3

Sawchuk, Informal Learning as a Speech-exchange
System: Implications for Knowledge Production, Power
and Social Transformation (2003)
More capable peer is not needed: two novices can
create own ZPD
"Indeed, by demonstrating how novices can themselves
collectively construct a ZPD in order to increase
individual and collective knowledgeability we engage
in a process of unsettling taken-for-granted themes of
power, control, and knowledge." (304)

Fernandez et al, Re-conceptualizing "Scaffolding" and the
Zone of Proximal Development in the Context of
Symmetrical Collaborative Learning (2001)
a) Disputational talk
b) Cumulative talk
c) Exploratory talk
“ One way of talking (disputational talk) restricts the group's
ZPD while another (exploratory talk) expands it. This group
version of the ZPD is no longer the product of a teacher's
conscious intention. It is better understood as a symmetrical
version of the concept of the Intermental Development Zone,
in which language is used in a dynamic and dialogical way
to maintain and develop a shared context."
ZPD and collaborative problem-solving

Why is ZPD applicable?
 Vygotsky
used this with child-adult dyad
 But can also be applied to a more capable peer


In collaborative problem resolution, each
participant comes in with different levels of
knowledge and experience
Problem-solving is a collaboration where each
participant is a “more capable other”
“Swarming”





Co-creation of knowledge through storytelling
Learning happens in the process of mastering a new
skill; collaborative problem-solving is mastering of a
challenge
Tacit to explicit knowledge
In collaboration, ZPD of each participant varies – and
the person with the greater knowledge is not
necessarily the one who would come up with the correct
answer – has to be within the ZPD for the person
Maybe if it is in the “already mastered” phase, people
are less likely to make new connections – they need to
stretch
Collaborative problem-solving

I have this
weird
case…

And that
also
explains
why…

Maybe
what

Bob had a similar
situation but in
that case…
Oh…I
know…what
happened was…

So the
story is…
“Reference scenarios can provide a resource: a similar problem, an already-worked-out
interpretation, or a possible solution arrived at in an analogous case. As precedents
enclosed in stories, scenarios are potentially relevant to all domains.” (Knorr-Cetina, 1999)
Conclusion





Concept of Zone of Proximal Development can be
applied not only to hierarchical learning, but also to
symmetric learning
Group problem-resolution is a type of collaborative
learning, or team sense-making
Knowledge is co-constructed through narrative
Tacit knowledge is converted into explicit
Next step: investigate models of group problemsolving
