Is there place for the individual construction within socio-cultural thinking? Labyrinth metaphor1
Aleksandar BAUCAL
University of Belgrade, Yugoslavia
In the field of cognitive development two broad clusters of scholars could be noticed. On the one side, individualistic approaches (Piagetian, neo-Piagetian, Information-processing approaches, Neural network, neuropsychology) take very abstract point of view (“bird” perspective) and produce theories about general aspects of the cognitive development. The main assumption is that all human beings share some characteristics that make them to be human beings. Our cognition is based on, embedded in and constrained by these characteristics. Their theories are stories about development out of any context (like Galileo's theory that offer an explanation of the free falling, but just if it happens in the vacuum). On the other side, socio-cultural approaches (Vygotskian, activity theory, situated cognition, narrative and discourse psychology) take closer look and produce theories about the way how the cognitive development is embedded in and formed by the socio-cultural context. The main assumption is that the very nature of human development is determined by the socio-cultural context in which it happens. Should we try to integrate them or it is better to believe that we are right and others are wrong? Based on results of my own studies, the paper will discuss a way that seems to me as a viable for the integration.
Taking a look at the actual landscape of the cognitive development field, it is
possible to notice at least two big clusters of scholars: constructivistic and co-
constructivistic ones.
Constructivistic campus
Constructivistic cluster (Piagetian, neo-Piagetian, Information-processing
approaches, Neural network, neuropsychology) has been mainly based on the
Piagetian and the cognitive psychology traditions. A common point of this way of
thinking is the assumption that the main mechanisms of the cognitive development
are internal ones. Every step in the cognitive development is mainly constructed
within “the skin of person”. Searching for the internal mechanisms has produced
several explanatory concepts like “assimilation”, “accommodation”, “strategy
construction”, “skills development”, “automatization” etc. During the last decade

this campus has been strongly supported by the development of the
neuropsychology of cognitive development that fits nicely within the constructivistic
reference frame. It adds neurophysiological mechanisms to the picture, and suggests
that behind at least some very basic cognitive mechanisms there are
neurophysiological ones. Therefore, during the time the constructivistic approach
has offered many concepts and methodological devices useful for analysis of the
universal, individual mechanisms of the cognitive development (if something like
that exists at all!).
Is there any place for so called “outside-of-skin” or the contextual factors in
the constructivistic picture? Although in some of constructivistic approaches the
contextual factors have been treated as a source of noise, the answer could be
positive one. The most of constructivistic theories have not neglected the contextual
influences on the cognitive development, but the socio-cultural context has not been
seen as a constructive factor. The context could modify dynamic aspects of the
cognitive development, but it cannot change the nature of developmental changes.
The changes, or developmental steps, are universal and constructed just through the
individual mechanisms, and the context could change just the time needed for
certain step (see picture 1).

Co-constructivistic campus
In the co-constructivistic campus there are also different conceptions (for
example: Vygotskian, activity theory, situated cognition, narrative and discourse
psychology etc.), but there is a common point: even if the universal, individual
mechanisms exist, it is far from enough for an explanation. It is necessary to include
the “outside-of-skin”, contextual factors in order to be able to understand the
cognitive development. The socio-cultural context cannot be treated as a source of
noise nor just as a factor that modifies the universal flow of cognitive development
since it is formative, constructive factor of the development. Some co-constructivistic
approaches have made a step forward claiming that the individual factors are just an
illusion co-constructed within a scientific community and has been reified. It means
the individual factors have been treated just as a source of noise (Sounds familiar?)
What is about researches?
Let’s take Piagetian kind of researches as an instance of the constructivistic
way of thinking. The studies of conservation demonstrate nicely the search just for
the individual and universal cognitive mechanisms (opening the internal cognitive

conflict, disequilibrium, assimilation, accommodation, equilibration, and
restructuration). The explanation is same for all children regardless of the historical
time, the socio-cultural and familiar context, characteristics of the child, and
characteristics of the testing situation and material.
Contrary, many researches show that all these contextual factors are relevant
(to mention just few of them, Donaldson, Perner, Light, Rommetveit, Perret-
Clermont etc.), i.e. it is not the same process if it takes place in different contexts,
with different children and in different situation. The Piagetian answer suggests that
the process of construction is the same, but specific characteristics of the context and
the child could modify the dynamic of the process. Therefore, all these differences
could be treated as a noise that should be overlooked in order to get insight into the
universalities.
Notwithstanding, what if the universalities do not exist at all, and what if the
noise is only one reality? Moreover, what if the individual construction is just
another myth created in the science labs, and what if the construction is always
embedded into the social interaction and actually means the co-construction? This
kind of questions has motivated number of studies with basic aim to get insight into
the “noise”, i.e. to get insight into the process of co-construction and its factors.
These studies (Wertsch, Rogoff, Perret-Clermont etc.) make our knowledge about the
co-construction richer, many new useful analytical concepts are (co)constructed (as if
“joint activity”, “scaffolding”, “negotiation”, “intersubjectivity” etc.) as well as new
methodological tools (analysis of discourse, interlocutor analysis etc.). Now, we have
better understanding how children develop new knowledge, skills, and abilities
through the process of co-construction embedded into identities and socio-cultural
context.
Construction vs. co-construction
Although the previous description has stressed differences and has been told
in the genre of dichotomy, it does not change an impression that the constructivistic
and co-constructivistic campus function relative separately and produce different
5
and opposite narratives about the main factor of cognitive development. Naturally,
it is not far away of the common sense to raise the question of possibility of
integration of these two ways of thinking, but the real issue is how to do that.
Starting point of the search for an integration: personal experience
Piaget and Vygotsky are a part of almost any textbook of the developmental
psychology, and their conceptions are presented more or less in a very similar way
as I did here. This discourse of polarization is very useful for teaching purpose,
especially when one wants to introduce students into the issue. The same story was
with me when I was an undergraduate student. At the first time I got impression
that Piaget and Vygotsky are really opposite points of the thinking about
development, and that it is not possible that both of them are right in the same time.
However, with time I change this impression and realized that Piaget and Vygotsky
could be complementary and not opposite conceptions.
Important source of this change were results of my researches. I will present
here two of them. First one was focused on the concept of cognitive structure in
Piaget’s theory (Baucal & Stepanović, 1999). The concept of global structure
(structures d'ensemble) is central one in Piaget's theory (i.e. Piaget, 1956, 1971).
Namely, if there are no global structures there are no global stages of cognitive
development (Piaget & Inhelder, 1966). The cognitive structure is functionally
superordinated to schemes in the sense that the structure determines basic
characteristics of action schemes which are part of the structure. Therefore the action
schemes have the same set of basic characteristics, and there is a basic similarity
among cognitive schemes (homogeneity of schemes). It means that a global cognitive
structure sets possibilities and constrains of children thinking, that is, determines
logical nature of problems that a child can or cannot understand and solve
(Corrigan, 1979). A structure is superordinated to cognitive schemes in
developmental sense too. According to Piaget, the basic developmental change is a
structural shift. When structure is reconstructed, it will induce correspondent
development of action schemes. Consequently, developmental changes of cognitive
6
schemes should occur at the same time (simultaneous schemes' development) since
these are determined by the same factor (Braine, 1959).
On the other side, many researches have demonstrated heterogeneity and
asynchrony both in concrete and formal operational tasks (Elkind, 1961; Piaget, 1969;
Ivić, 1990; Brainerd, 1973; Katz & Beilin, 1976; Miller, 1976; Wason, 1977; Hooper,
Toniolo & Sipple, 1978), and these results are treated as counter arguments to the
concept of global structure. For example, Elkind shows that majority of children at
the age of 7 (and older) understand the conservation of mass, by the age of 9 (and
older) a majority of children understand also the conservation of weight, and the
conservation of volume is not understood until the age of 11.
In order to "assimilate" these facts in his theory, Piaget (1941, 1969)
formulated hypothesis called "horizontal décalage" (in the further text: HD).
Although, there are a few interpretations of the horizontal décalage (Lourenço &
Machado, 1996), even in Piaget's text (Pinard & Laurendeau, 1969; Gruber &
Vonèche, 1995), it seems to us that there is agreement that the HD hypothesis define
two factors which determine performance on tasks of the same logical form.
The first factor is cognitive structure which is necessary but not sufficient: if a
structure necessary for understanding the logical form of task is developed, then a
child has competence to understand and to solve all tasks of this kind. However,
having a competence is not sufficient for solving a task of this kind. On the other
side, if necessary cognitive structure is not developed, then a child is certainly not be
able to understand and to solve any task of corresponding logical form. The second
factor, which determines performance on a task, is specific content of a task that
determines if a child, who develops necessary cognitive structure, will solve a
specific task of corresponding logical form. Namely, tasks of the same logical form
may differ in content. They are formally same, but they have different contents.
Content of a task is important because it determines degree of resistance which task
offers when one try to apply certain cognitive structure onto the task. If a task offers
lower degree of difficulty, a child will be able to apply a structure easier, and will
solve the task earlier.
7
It seemed to me that better test for Piaget’s conception of structure would be if
it would be tested by tasks of same logical form and content. If the horizontal
décalage would be happened in this case as well, it would be something what Piaget
conception cannot explain. But, the problem was how to define more tasks that
would be the same according to the form and content. To made different version of
the conservation task we varied the type of starting relation between two glasses
regarding to the quantity of water. Namely, in the standard version of task, two
glasses contain equal amount of water (A=B). We made two additional tasks by
changing the starting relation between amount of water in the two glasses. In the
first additional task, glass A contains more water than glass B (A>B), and in the
second additional task, glass A contains less water than glass B (A<B). Thus, there
are three conservation of liquid quantity tasks, which have same logical form and
same content (see picture 3).
Speaking frankly, I expected that children performance will be different at
these three tasks and that it will be stronger evidence against the concept of structure
than it was the case with previous studies that used tasks of different content.
However, the result was unexpected for me. About 88% of children showed
homogenous performance on these tasks, i.e. 88% of children solved or didn’t solve
all three tasks. Other 12% of children didn’t show the décalage pattern of results, and
it seemed that they are distributed by chance in the categories defined by some type
of heterogonous performance (see table 1)

The research was repeated but with three conservation tasks: conservation of
number, conservation of discontinuous material (pearls), and conservation of
continuous material (water). For every of these tasks three different tasks were
constructed by varying the starting relation. And the results were similar to the
previous study - about 80% of children demonstrated homogenous performance, but
there was significant difference respect to the age of children who were successful on
three different conservation tasks: (a) children who solve all conservation of number
tasks - around 6;2 (exact: 73.90 months, SD=5.11 months), (b) children who solve all
conservation of pearls quantity – 7;4 (exact: 88.37 months, SD=6.36 months), and (c)
children who solve all conservation of liquid quantity – 7;11 (exact: 95.31 months,
SD=3.98 months). The One-way ANOVA showed that there were statistical
significant differences between these mean age: F(2,102) =131.93, p<.000. In sum,
these results fit nicely to the horizontal décalage hypothesis, and suggest that it is
useful to make distinctions between competence (to be able to solve some kind of
problem based on certain kind of thinking) and performance (to be able to apply
existing kind of thinking under certain circumstances).
The second research dealt with the concept of Zone of proximal development
(ZPD). To demonstrate value of the ZPD, Vygotsky used the following example: two
children have the same score when they are tested individually, but when they are
tested with help of adult one child shows bigger progress than other one. Based on
that Vygotsky concluded that it is necessary to make distinction between what the
child is able to perform alone, and what (s)he is able to perform with the help of
adult. First score indicate the level of actual development (abilities that are already
developed), and second one indicate the ZPD (abilities that are in the process of
development and that cannot utilized alone, but that can be utilized with the help of
adult). It is needed to stress that Vygotsky didn’t think that the social interaction
with adult just help the child to actualize some hidden ability, but he claimed that
children built new abilities through the interaction with adult that will be
internalized into the individual ability. On that way, the co-construction is
established as a main factor of development (see picture 4)
9
Many researches demonstrated that this idea of Vygotsky is sound and how
the new ideas and abilities could be co-constructed through interaction with adult or
peer (for example: Wertsch et. al, 1980; Brown & Ferrara, 1985; Perret-Clermont,
1980…), but still some questions are opened. I was interested in the complexity of
the social interaction as a factor of development. The interaction between the child
and the adult is a complex phenomenon with different aspects, so I wondered what
aspect of the social interaction is effective?.
In order to approach this issue I realized a study with the following questions
in my mind.
1. What is the relation between the Level of actual development (LAD) and
the ZPD? Based on the example offered by Vygotsky that it is possible that two
children could have same LAD, but different ZPD, it follows just that the correlation
between LAD and ZPD is not 1. From this example it is not possible to answer what
is correlation between LAD and ZPD. Is it zero correlation, what would mean that
the child with some measure o the LAD could have any measure on the ZPD? Is it
negative one, what would mean that children with higher LAD have somewhat
smaller ZPD? Or, is it positive one, what would suggest that children with higher
LAD would progress more with the help of others?
2. Is the effect of shared problem solving durable or it disappears in time? If
the social interaction is formative (constructive) factor it means that its effect has to
be relatively durable.
3. Do we know something more about future development level based on
the ZPD, that we don’t already know from the LAD? If the social interaction is
formative (constructive) factor and if the effect of shared activity is durable it follows
that one has to have better prediction of future developmental level by the ZPD and
LAD, than just by the LAD.
4. What aspects of the social interaction is the most effective with respect to
the future developmental level? Let’s divide the social interaction into motivational
component (when the adult simply support the child to do better without any kind
of cognitive scaffolding), and cognitive component (when the adult helps to the child
to solve task performing some activities necessary for find out the solution that are
10
difficult for the child). If the social interaction is constructive factor of development it
means that the cognitive component has to be more predictive for the future
developmental level than the motivational component.
The design of the study is presented at the picture 5. That was a pre-post test
design. As an instrument for testing the LAD the Raven’s matrices were used.
Participants in the study were children 8-12 years old from a primary school from
Belgrade. In the pre-test phase whole class of children was tested in the same time –
the experimenter gave to every child a copy of test, read the instruction to the whole
class, and children were doing the test individually. Based on the individual score on
the Raven’s test children were divided into two groups that had the same
distribution of scores: experimental and control group. After two weeks children
from both groups were tested again with the same test, but that time every child was
doing the test in somewhat different conditions. Every child came into an office in
the school. The experimenter read the instruction to the child, and the child worked
on tasks individually. Children from the control group processed like that until the
end of the test, but children from the experimental group had different arrangement.
If some child was not able to solve certain task (s)he got a help. The help was
gradual. After first fail, the experimenter gave to the child the motivational help (for
example “Try again, you can do that”). If the child was not able to solve the task
after that kind of help, the experimenter tried with more help. The second level of
help was to analyze relations between elements in the rows of the matrice (the
cognitive 1 help). If the child was not able to solve the task with this level of help,
the experimenter made an analysis of relations between elements in the columns of
the matrice (the cognitive 2 help). If it didn’t help to the child to find out the right
answer, the experimenter made an integrated analysis of the relations between
elements in the rows and columns of the matrice (the cognitive 4 help). Therefore,
for every child from the control group there was just one information – the number
of tasks (s)he was able to solve. Every child from the experimental group was
described by the six numbers: the number of tasks (s)he was able to solve
individually, the number of tasks (s)he solved with every level of help, and the
number of tasks (s)he was not able to solve even with the help of the experimenter.
11
The LAD was defined by the number of tasks the child was able to solve
individually, but the question was how to calculate the ZPD score. Starting from the
idea that if the child need more help with certain task it means that the ZPD of the
child for this task is smaller, the following equation was used for calculation of the
ZPD score:
Legend: H1, H2, H3, H4 – the number of tasks the child solved with different levels of help NI – total number of tasks (NI = 60) I1 – the number of tasks the child solved individually (the LAD score)
The results showed that the correlation between the LAD and the ZPD was
statistically significant and was about +0.3. It means that children who had bigger
the LAD progressed more through the interaction with the experimenter.
The results also showed that the interaction with the experimenter had effect
on the children from the experimental group, and moreover this effect was durable
(see graph 1).
From the graph 1, it could be seen that both groups of children solved in
average about 35 out of 60 tasks individually. Children from the experimental group
were able to do much more with the help, so in average they solved about 55 tasks!

However, after two months the average score of the experimental group was not so
good (about 44), but still it was higher than the score of the control group (that
stayed unchanged for that period). It means that children from the experimental
group really got something through the social interaction. Moreover, the multiple
regression showed that the ZPD predict the future score over and above the LAD,
what means that both the LAD and the ZPD contribute to the future developmental
level. All these findings fit very well to the co-construction conception.
But, further analysis showed that mostlz motivational aspect of the social
interaction was effective! That was concluded from the following facts: (a) the
multiple regression showed that motivational level of help can explain alone the
effect of shared activity, and (b) for tasks which were solved in the post-test, but not
in the pre-test in the most cases the motivational help was enough for success.
This finding suggests that children didn’t construct some new ability through
the shared activity, but became better in utilization of already existing abilities. To
explain that, it is useful to make again distinction between the competence and the
performance. Therefore, in the individual testing children don’t do what they can,
but their performance is usually result of their competence, but also of different
factors that can influence children’s performance (the motivation of children, the
meaning of the activity, physical and social conditions etc.). The solving the same
tasks with somebody else could (at least in some cases) help to the child just to
utilize better her/his competence, and not to be “field” for co-construction of some
new competence. Following that, it means that it is not enough to show that
children can make better with the help of adult to conclude that the social interaction
is constructive factor of development.
Labyrinth metaphor: a way for integration
These results were unexpected for me. That moves me to consider again the
relationship between Piagetian and Vygotskian conception, and to wonder if there is
a way to keep the social interaction as a main factor of development, but to find also
13
some place for the individual activity within it. Now I would like to share with you
some reflections about the issue.
First, I will discuss about the individual activity being in the focus of Piaget
theory to define better the scope of his conception and to find out what it can be
actually learned from this theory. Then, I will present the Labyrinth metaphor that
can facilitate defining of a model in which the construction and the co-construction
would be integrated. Finally, I will present how the Labyrinth metaphor helps me to
understand some aspects of Serbian education and sources of resistance to the
reform.
What Piaget theory is about at all?
Piaget defined own scientific project as genetic epistemology in the book
Recherche (1918) at the beginning of his career (Chapman, 1988). Kitchener noticed
"Piaget is not a child psychologist in the usual sense of the term. As he has always
insisted, he is genetic epistemologist" (1986, p. 1). According to that, Piaget seems to
be interested primary in the ontological characteristics of the human reason. He
followed the rationalistic tradition and assumed that every human being (past,
actual and future) is born with potential to develop her/his own version of the
universal human reason through interaction with objects. It is the same as if any
human being is born with potential to develop idiosyncratic version of heart, lungs,
or some other organ based on universal human form of heart, lungs etc. Because of
that it is important for Piaget's genetic epistemology to made distinction between the
psychological subject "centered in the conscious ego whose functional rôle is
incontestable, but which is not the origin of any structure of general knowledge"
(Beth & Piaget, 1966, p. 308) and the epistemic subject "which is common to all subjects
at the same level of development, whose cognitive structures derive from the most
general mechanisms of the co-ordination of actions." (Beth & Piaget, 1966, p. 308).
The distinction is important because the former is subject of the psychology, and the
later of the genetic epistemology.
14
Hence, Piaget's researches of cognitive development were in function of the
genetic epistemology, i.e. that was an empirical approach to the development of the
epistemic subject (Piaget, 1970; Piaget, 1972; Piaget, 1973). In my understanding, the
epistemic subject means idealized thinker. To find out what would be characteristics
of the idealized thinker one needs to abstract the human reasoning completely from the
external context (history, culture, social system, immediate personal and physical context) as
well as of the internal context (personality, affectivity, motivation, knowledge about content
of thinking, attention, memory etc.). Piaget assumed that there are such features and
that these characteristics constitute the human reason (the human competence).
Consequently, in empirical researches, Piaget tended to abstract children's
logic from all other aspects of the external and internal context and to find out the
epistemic subject. For example, when one read protocols it is obvious that Piaget
paid attention to context, child's personality and interest, verbal formulation of
questions etc. However, his main aim was to abstract the way how the child reason
from the context in which it was embedded. The child’s personality, the way of
speaking, the mood etc. were important especially as possible obstacles that can blur
the expression of the child's logic. Because of that, Piaget changed verbal
formulations, motivate the child etc. during the interview with aim to "detour" these
other aspects and to get insight into the core quality of the child's reasoning. Piaget
did not deny importance of other aspects for the process of reasoning of the child
when (s)he is solving certain task, but he was interested in the "ideal" form of
children's reasoning, and its development through interaction and relation with
objects. In searching for the epistemic subject Piaget made many interviews, but it is
also important to notice that the idealized thinker cannot be described by the modal
way of reasoning of interviewed children because the modal/average doesn’t
describe the cognitive potentials of children, i.e. what is the child's competence. 2
2 Namely, any child is developed under certain conditions which are less favorable than the ideal conditions for development of the human reason. It follows that the reason of any real child is more or less under the potential of the child competence at the certain level of development, and that the modal/average performance of a representative sample of children is not appropriate indicator. In this sense Piaget’s theory is closer to the scientific thinking than to the thinking of real children who develop in real socio-cultural context because the scientific thinking is the most decentered kind of human thinking, and as such better indicator of the human cognitive competence. That was reason why Piaget studied the way how the new concepts and ideas are constructed in different sciences.
15
Thus, in this sense it could be said that Piaget's theory is not about
development of real children in real socio-cultural context, but about development of
idealized epistemic subject, and it explains: (a) why Piaget tended to find out the
most abstract characteristics of examined children, (b) why he was interested in form
and qualitative changes of children reasoning, (c) why he was interested in children
competence, not performance, and (d) why Piaget was interested in general
characteristics of children's reasoning, and not in characteristics of any special group
of children.
What aspects of the cognitive development can be found in Piaget's theory and what
aspects stay out of it? Thus, Piaget's theory is a theory of development (i.e.
"embryogenesis") of the epistemic subject. According to the theory, the epistemic
subject passes through four stages that are different according to the quality of its
logic. These stages define universal, necessary and ideal path of development of
human reason.
It is universal because the epistemic subject is the ontological trait of human
being, but it does not mean that every human being has to pass through all stages. It
depends on conditions and context in which (s)he is developed.
It is necessary in the sense that order of stages is fixed, but not in the sense that
any children have to reach the last stage. Stages follow each other in the fix order
because: (a) the main mechanisms of the development are equilibration and
reflective abstraction, and (b) every stage is defined as a formalization of previous
one.
This path of development is ideal in few ways. First, it is ideal because this is a
chart of development of the ideal knower. Second, it describes development of
cognitive competence, and not performance. In other words, if the child is at the
concrete operational stage it means that (s)he has potential to solve any task with
logical form that is understandable by the concrete operation. It does not mean that
the child will solve any such task in any time and any context. Third, it does not
describe real development of real children, but only potential path of development
which would be realized under the ideal conditions for development of human
reason. And fourth, because of all previous, it is ideal in the sense that represent
16
norm of development, i.e. the ideal end point that cannot be reachable in reality, but
which govern the process of construction according to principle of orthogenesis:
"Although never entirely realized as an ideal, reason is a form of equilibrium toward
which all cognitive system aim, no matter how little equilibrium they may have"
(Piaget, 1995, p. 227). 3
It seems to me that Piaget theory could be compared with Galileo's theory of
the free falling4. Namely, Galileo claimed that there is only one factor which
determines free falling of all objects (regardless to their physical characteristics)
under all circumstances. And in that sense this factor is something generic and
universal for every instance of free falling. To stress this factor he imagined what
would be happened when two objects (same according all other aspects except to
weight) would fall freely, not in the real circumstances, but in the vacuum. Vacuum
is an ideal or idealized context since it represents condition in which all factors
relevant in the real conditions are kept constant. In a real context these factors
determine time needed for free falling of certain kind of object, and because of them
it would be easy to find two real objects which would fall freely with different
velocities in real condition (for example: a feather and a stone). However, to show
that a feather falls much slower than a stone would not be contra-argument for
Galileo's conception because he said nothing about falling of real objects under real
conditions.
Following this analogy, it could be said that Piaget's approach dealt with the
idealized epistemic subject, which represent universal and ontological aspects of
human reason, and its development within the idealized kind of social context. It
means also that the psychological subject stayed out of scope of his theory as well as
Galileo did not deal with free falling of real objects in real conditions. Reasoning of
certain child or adult is embedded necessarily into certain kind of cognitive system
(attention, short and long memory etc.), personality, and certain historical and social
3 There are many misunderstand of the nature of Piaget's theory, and consequently about implication of this theory. Here we stress two important implications that are sometimes wrongly understood: (a) the correspondence between age and stages is not necessary, (b) it is not necessary to reach the last stage, and (c) if the child is at certain stage and if development goes further than the following stage must have specific characteristic. 4 Any two things would fall in the same time on the ground regardless of their weight.

context, and it develops as an integral part of the external and internal context.
Piaget put attention on the "ideal organization", and not on the cognitive functioning
and development of real, "unideal" children who are developing within some kind of
socio-cultural context.
Based on all that, it could be concluded that Piaget theory tells a story about
individual construction as a universal potential of the human reason and individual
construction as a factor that is present in all situations (in the same way as
gravitation is present in every case of falling), but it doesn’t tell something about this
potential in real conditions (how it is embedded into some real child, how it is
developed and modified by socio-cultural context etc.).
What is relationship between Piaget and Vygotsky?
It seems to me that it is not proper to think about Piaget and Vygotsky as
conceptions that are opposite to each other. In my view, these conceptions are
complement to each other. Complementary to Piaget, Vygotsky was interested in the
development of real children in the real socio-cultural context, and not in
development of the idealized subject in the idealized context. Taking again the
analogy with Galileo, it means that Vygotsky would be interested to explain the free
falling of some real object under some real circumstances, i.e. to explain why a
feather under certain conditions fall freely in certain way. Or what was abstracted by
Piaget that was included in consideration by Vygotsky.
If one accept this way of thinking about relationship between Piaget and
Vygotsky than the question who is right stop to be relevant in the same way in
which it would be irrelevant if one would ask a physician what is more important to
understand: the ideal kind of free falling or to understand what and how determines
free falling of some object under certain conditions.
Labyrinth metaphor as a thinking tool in a search for integration
18
Faced with the dichotomy the “construction vs. co-construction” and having
in mind results and reflections mentioned above, I decided to try to escape from the
dichotomy, to play a little and try to find a model in which there would be place for
both construction and co-construction. The model is intended to be about
development of real children embedded in a real socio-cultural context and
developed through interaction with the context, but also to show how the individual
activity can be significant factor of development that is basically constructed by the
socio-cultural context.
I started with the fact that even if there are universal features of the human
reason the question is what is going on with them when they are embedded into
certain socio-cultural context. From Piaget’s point of view that is something what
should be abstracted, but for the developmental psychology this is not a case
because no one child on this world develops in the idealized context (imagined by
the scientists in order to make thinking experiments). Every child is born and
her/his development is unfolding in very specific socio-cultural context that is not
built to meet developmental needs of the epistemic subject, but for other purposes.
And this is a place for the labyrinth metaphor. I imagine the socio-cultural
context as a Labyrinth. There are different channels that are built by the previous
generation. Some of these channels have been used by many people and many
generations what have made them to have special place in the Labyrinth. These
channels are big and beaten, and there are many tools that support members of
community to use these routs. Some other channels are also old ones, but they are
not used anymore or they are used just by some members of the community. For
some of these unused channels there are also tools that should prevent members to
use these routs. There are some new channels as well that are just in the process of
building.
Every channel is basically defined by its walls. Let’s imagine that walls are
very fluid at the beginning of building of certain channel, and that with passing of
every member walls become more fixed and harder. Also, in the beginning, when
walls are the most flexible, every user can modify walls according to her/his needs.
For example, if one doesn’t feel comfortable with certain walls in a very new
19
channel, (s)he can simply reshape it without big resistance. During the time and
proportionally to, for example, the number of passings through a channel its walls
become more and more fixed. Therefore, in the very old channels (no matter if they
are used in the present) walls are very hard and almost fixed, so people who passing
through it cannot make changes, but just use it.
Let’s imagine now a child born in certain Labyrinth. Even if every human
baby has certain universal, ontological features that make her/him to be a human
baby, the activity of imagined child will be mainly organized and formed by the
structure of Labyrinth. Moreover, if the child is engaged in some kind of activity for
a long time it will support development of such mental forms that fit to the structure
of activity. It means also that the locus of control of activity is changed from external
to internal one what makes this form of activity less dependant of the context. Since
channels determine mainly the kind and structure of children activity and since the
structure of channels is relatively persistent factor, it can be concluded that the child
will develop such mental structures that fit to the Labyrinth.
Of course, in the most cases the child activity in the Labyrinth would be
mediated by the adult, and because of that the structure of the child’s activity would
be co-constructed. But still the co-construction would shape the structure of the
child’s activity and serve as an external locus of control at least until the
development of mental counterparts are developed. It means that the co-
construction factors always include the individual activity!
However, there would be cases when the child’s activity is not mediated by
the others, but it happens through direct interaction with the structure of Labyrinth.
Looking from Piaget point of view that would be an example how mental
development is constructed through individual activity. However, that would be
just half of the story. In these cases, the influence of social-cultural factors is hidden
because their influence is indirect via previous structuration of the Labyrinth. So, it
means that there is no clear-cut case of the individual activity in the Labyrinth!
Therefore, the playing with the Labyrinth metaphor brings us to an
interesting conclusion: the co-construction always includes the individual activity,
20
and every individual activity is shaped directly or indirectly by the socio-cultural
context!
Education in Serbia: An example of the use of the Labyrinth metaphor
Almost a year I am member of a team who is dealing with the reform of the
education system in Serbia.
Of course, the reform started with an analysis of previous education system.
What was striking to me was big gap between what were planned goals of education
and what was realized. The results of a big study about effects of primary education
can serve as an illustration of this gap. It was found that somewhat more than 50% of
students learned less than half of the most important concepts from curriculum (it
was selected just 25% of concepts that were estimated as the most important by the
group of psychologists, university teachers, and teachers from primary schools).
More specifically, it was really striking to be faced with the fact that huge number of
students was not able to do some very basic tasks. It was also interesting to see the
reaction of teachers from primary schools when we discussed this finding. Many of
them believed that our education had serious problems, but that was too much for
them. They were sure that very little number of students were not able to do some of
very basic tasks, and they didn’t believe at all in results.
Thinking about these findings I ask myself: does it mean that our education is
not effective at all? Does it mean that students just sitting there and learn nothing?
Does it mean that students just lost their time in the school? And if this is like that,
how it is possible that there was no red alert?
But, taking the Labyrinth metaphor as a reference frame I realized that I
should change the focus of my attention. I realized that I should not look at what is
declared as a goal of education, and to think about gap between what was intended
and what was realized respect to the declared goals. I realized that more important is
to look at the structure of activity of students within education process because that
is the place where educational effects are produced.
21
Very briefly, when I focused at the structure of activity in the school and how
it is canalized, I realized how the education process was settled on a way as if the
goal was not to produce knowledge or declared goals, but to support development
of obedience, uncritical acceptance of authority and power relations, passivity etc.
And, I also realized that these effects were even more important for the kind of
society we lived in than the declared education goals were! Somehow, that kind of
education fitted nicely to the socio-cultural context! As if the education was a
Labyrinth with such channels that forced kinds of activity appropriate to the nature
of society.
Moreover, since teachers were also included into this kind of activity they
were also shaped by it. And, since this kind of activity lasted for very long time,
many teachers were developed such mental structures that serve as the internal
locus of that kind of activity. I found also that it could be a reason why many
teachers resist to the reform in spite of the fact that many of them would say that we
need to change our education.
