the “nouvelle vague”
and its effects on
education

2. contents
• 1. give a panoramic view of the “new wave
of studies” in cognitive sciences and
technologies
• cognition is decentralized
• 2. discuss related educational models
• constructivism
• 3. analyze the relationship between 1. et 2.
3. 1. Nouvelle vague in cognitive sciences
different
approaches that can
be described as the
“nouvelle vague” in
cognitive sciences ...
... only family
resemblances
4. • the mind-computer metaphor “Boiled down
to its essence, cognitive science proclaims
that in one way or another our minds are
computers” [Dennett, 1993, p. 126]
• critical attitude towards the “classic cognitive
sciences” (...another gerrymandered group of approaches to
cognition)
• cognitive processes are not (necessarily) centralized
• criticism towards the massive recourse to internal
representations: cognition is not (limited) to being the
mirror of reality
• cognitive processes are not necessarily formal, logical
operations
5. decentralization

choreographed dance
troupe, the birds veer to the

coordinated. ... How do birds

of rules and reacts to
keep their movement so the movements of the
orderly, so coordinate?

12. 2. Nouvelle vague and education
how do these
approaches affect
theories of learning
and knowlege
acquisition through
education?
13. epistemological
pluralism
• another expression of decentralization, embodiment, situation
and distribution of knowledge is the challenge to the egemony
of logical, abstract, formal reasoning >
• validity of multiple ways of thinking and knowing >
• rehabilitation of concrete, informal, sensori-motor forms
of knowledge acquisition in face of abstract, formal, logical
cognition and knowledge acquisition
14. concrete knowledge
• contextual and social
construction of
knowledge, role of social
factors vs role of
reasoning and
experimentation • “formal reasoning is not a stage
but a style” (Turkle & Papert,
• feminist approaches to 1992)
epitemology
• sociology of scientific
knowledge
15. Piaget: genetic epistemology
• explain the acquisition of (scientific) knowledge through its
genetic development (stages): successive development of
cognitive capacities, from concrete to abstract
• sensorimotor stage of cognitive development: 0-2 > perceptual
concepts that cannot be manipulated; preoperational: 2-7 >
language and symbolic play, but still hands-on and learning by
doing
• concrete operational, formal operational: 7-11 > logical
concepts (reversible), from the concrete (personal experience)
to the abstract
• scholar curricula reflect this view
16. Bruner: enactive knowledge
• Stages are forms of knowledge and learning; learning is re-
organization
• 3 forms of knowledge/representation:
• symbolic: language-based representations (manipulation of
symbols)
• iconic: image-related representations (mental images tht
cannot be manipulated)
• enactive: learning by doing, action-related representations (the
action is the representation: i.e. driving)
• enactive knowledge is lifelong (as Resnick’s lifelong kindergarten)
17. Bruner: educational
principles
• instruction should be based on knowledge about cognition
• knowledge = re-arranging
• learning is an active process through which learners build
their knowledge based on past knowledge experiences
and readiness (will and capacity to know): spiral curricula
• knowledge = co-presence of stages
• education should propose the three forms of
representation in sequence for each new task/material;
any material can be taught at any moment of the life of
the child
18. Bruner: constructivism
• constructivism =
discovery, through
manipulation and • "The concept of prime numbers appears to be
perception but also more readily grasped when the child, through
construction, discovers that certain handfuls of
through more beans cannot be laid out in completed rows and
abstract columns. Such quantities have either to be laid
out in a single file or in an incomplete row-
transformations of column design in which there is always one extra
information, or one too few to fill the pattern. These
patterns, the child learns, happen to be called
construction of prime. It is easy for the child to go from this step
hypotheses to the recognition that a multiple table so
called, is a record sheet of quantities in
• manipulation both completed mutiple rows and columns. Here is
factoring, multiplication and primes in a
in the physical and construction that can be visualized."
in the metaphorical
sense
19. Papert: constructionism
• Seymour Papert (1991) : proposes a form of
education in which learning passes through design
(rather than through observation or instructions)
• importance of tangibility, personal access and
construction (also in the metaphorical sense)
•
20. constructionism &
technology
• computers make the kindergarten become lifelong
• “computers provide a context for the development of
concrete thinking” (Turkle & Papert, 1992)
• because of the possibility of perceiving abstract things:
computers are at the interface between abstract things
and physical things
• because of the possibility of designing and
personalizing
21. • Logo turtles for teaching mathematics
• turtles are robots connected to a computer; the child drives
the turtle by using directional and distance commands
• “the turtle makes possible a new approach to thinking about
geometry, contrasting sharply with the Euclidean methods
traditionally taught in the classroom. ... The turtle connects to
the children’s experience in the world - children can ‘play
turtle’, imagining themselves as the turtle
• Logo turtles can be purely virtual: manipulations and
transformations of computer, digital repesentations
22. 3. The two aspects of construction: physical and
metaphorical
which is the
relationship between
decentralization (of
mind processes) and
constructivism (as a
model for education
and learning) ?
23. two aspects of
constructivism
• constructivism/concrete knowledge =
hands-on as a physical process of tangible manipulation
• constructivism/concrete knowledge =
hands-on as a metaphorical process
of transformation, discovery and design =
hands-on head-on
24. hands-on
• one can have hands on and
• hands-on: follow a set of instructions
• interfaces based on action • constructivism is design:
and perception: virtual creating things
objects are manipulated
• “create tools that engage
• representations of learners in construction,
invention, experimentation.
concrete objects
This process involves at least
• representations of two levels of design:
abstract objects educators need to design
things that allow students to
• haptic sensors and
design things” (Resnick,
actuators: haptic

25. • epistemological pluralism

which is as adult and

no other relation with

decentralization are not
necessarily alternatives to

can be integrated

actions but reproaches 2

misunderstanding the role of necessity, but admitted;
