Vygotsky Stated That Development is a Continuous Process Propelled by
Vygotsky's Sociocultural Theory: Vygotsky is best known for being an educational psychologist with a sociocultural theory. This theory suggests that social interaction leads to continuous step-by-step changes in children's thought and behavior that can vary greatly from culture to culture(Woolfolk, 1998). Basically Vygotsky's theory suggests that development depends on interaction with people and the tools that the culture provides to help form their own view of the world. There are three ways a cultural tool can be passed from one individual to another. The first one is imitative learning, where one person tries to imitate or copy another. The second way is by instructed learning which involves remembering the instructions of the teacher and then using these instructions to self-regulate. The final way that cultural tools are passed to others is through collaborative learning, which involves a group of peers who strive to understand each other and work together to learn a specific skill (Tomasello, et al., 1993).
His theory combines the social environment and cognition. Children will acquire the ways of thinking and behaving that make up a culture by interacting with a more knowledgeable person. Vygotsky believed that social interaction will lead to ongoing changes in a child's thought and behavior. Theses thoughts and behaviors would vary between cultures (Berk, 1994).
The second element in the sociocultural theory is the zone of proximal development (ZPD). Vygotsky believed that any pedagogy creates learning processes that lead to development and this sequence results in zones of proximal development. It's the concept that a child accomplishes a task that he/she cannot do alone, with the help from a more skilled person. Vygotsky also described the ZPD as the difference between the actual development level as determined by individual problem solving and the level of potential development as determined through problem solving under adult guidance or collaboration with more knowledgeable peers. The result of this process is children become more socialized in the dominant culture and it induces cognitive development (Moll, 1994).
In order for the ZPD to be such a success, it must contain two features. The first is called subjectivity. This term describes the process of two individuals begin a task with different understanding and eventually arrive at a shared understanding. The second feature is scaffolding, which refers to a change in the social support over the course of a teaching session. If scaffolding is successful, a child's mastery level of performance can change, which means that it can increase a child's performance on a particular task.
The zone of proximal development has implications for assessment, especially concerning children with learning and behavior problems. In the book,Scaffolding Children's Learning, Berk and Winsler discuss Vygotsky's dissatisfaction with the ability and achievement tests as valid measures of children's capacity to learn. Two children can differ substantially in the ZPD's. One child may do his/her best on their own, while the other needs some assistance. Therefore, the ZPD is crucial for identifying each child's readiness to benefit from instruction.
Comparison of Vygotsky and Piaget: Vygotsky's ideas and theories are often compared to Jean Piaget, especially his cognitive- developmental theory. They had a conflict explaining that development concepts should not be taught until children are in the appropriate developmental stage. Opposing Vygotsky's zone of proximal development, Piaget believed that the most important source of cognition is the children themselves. But Vygotsky argued that the social environment could help the child's cognitive development. The social environment is an important factor which helps the child culturally adapt to new situations when needed. Both Vygotsky and Piaget had the common goal of finding out how children master ideas and then translate them into speech.
Piaget found that children act independently on the physical world to discover what it has to offer. Vygotsky, on the other hand, wrote inThought and Language that human mental activity is the result of social learning. As children master tasks they will engage in cooperative dialogues with others, which led Vygotsky to believe that acquisition of language is the most influential moment in a child's life.
In conclusion, Piaget emphasized universal cognitive change and Vygotsky's theory leads us to expect highly variable development , depending on the child's cultural experiences to the environment. Piaget's theory emphasized the natural line, while Vygotsky favored the cultural line of development.
Lev Vygotsky
The work of Lev Vygotsky (1934) has become the foundation of much research and theory in cognitive development over the past several decades, particularly of what has become known as Social Development Theory.
Vygotsky's theories stress the fundamental role of social interaction in the development of cognition Vygotsky, 1978), as he believed strongly that community plays a central role in the process of "making meaning."
Unlike Piaget's notion that childrens' development must necessarily precede their learning, Vygotsky argued, " learning is a necessary and universal aspect of the process of developing culturally organized, specifically human psychological function
" (1978, p. 90). In other words, social learning tends to precede (i.e. come before) development.
Vygotsky has developed a sociocultural approach to cognitive development. He developed his theories at around the same time asJean Piaget was starting to develop his ideas (1920's and 30's), but he died at the age of 38 and so his theories are incomplete - although some of his writings are still being translated from Russian.
No single principle (such as Piaget's equilibration) can account for development. Individual development cannot be understood without reference to the social and cultural context within which it is embedded. Higher mental processes in the individual have their origin in social processes.
Vygotsky's theory differs from that of Piaget in a number of important ways:
1: Vygotsky places more emphasis on culture affecting/shaping cognitive development - this contradicts Piaget's view of universal stages and content of development. (Vygotsky does not refer to stages in the way that Piaget does).
- (i) Hence Vygotsky assumes cognitive development varies across cultures, whereas Piaget states cognitive development is mostly universal across cultures.
2: Vygotsky places considerably more emphasis on social factors contributing to cognitive development (Piaget is criticized for underestimating this).
- (i) Vygotsky states cognitive development stems from social interactions from guided learning within the zone of proximal development as children and their partners co-construct knowledge. In contrast Piaget maintains that cognitive development stems largely from independent explorations in which children construct knowledge of their own.
(ii) For Vygotsky, the environment in which children grow up will influence how they think and what they think about.
3: Vygotsky places more (and different) emphasis on the role of language in cognitive development (again Piaget is criticized for lack of emphasis on this). For Vygotsky, cognitive development results from an internalization of language.
4: According to Piaget, language depends on thought for its development (i.e. thought comes before language). For Vygotsky, thought and language are initially separate systems from the beginning of life, merging at around three years of age, producing verbal thought (inner speech).
Effects of Culture: - Tools of intellectual adaptation
Like Piaget, Vygotsky claimed that infants are born with the basic materials/abilities for intellectual development - Piaget focuses on motor reflexes and sensory abilities.
Lev Vygotsky refers toElementary Mental Functions –
o Attention
o Sensation
o Perception
o Memory
Eventually, through interaction within the sociocultural environment, these are developed into more sophisticated and effective mental processes/strategies which he refers to asHigher Mental Functions.
For example, memory in young children this is limited by biological factors. However, culture determines the type of memory strategy we develop. E.g., in our culture we learn note-taking to aid memory, but in pre-literate societies other strategies must be developed, such as tying knots in string to remember, or carrying pebbles, or repetition of the names of ancestors until large numbers can be repeated.
Vygotsky refers to tools of intellectual adaptation - these allow children to use the basic mental functions more effectively/adaptively, and these are culturally determined (e.g. memory mnemonics, mind maps).
Vygotsky therefore sees cognitive functions, even those carried out alone, as affected by the beliefs, values and tools of intellectual adaptation of the culture in which a person develops and therefore socio-culturally determined. The tools of intellectual adaptation therefore vary from culture to culture - as in the memory example.
Social Influences on Cognitive Development
Like Piaget, Vygotsky believes that young children are curious and actively involved in their own learning and the discovery and development of new understandings/schema. However, Vygotsky placed more emphasis on social contributions to the process of development, whereas Piaget emphasized self-initiated discovery.
According to Vygotsky (1978), much important learning by the child occurs through social interaction with a skillful tutor. The tutor may model behaviors and/or provide verbal instructions for the child. Vygotsky refers to this as cooperative or collaborative dialogue. The child seeks to understand the actions or instructions provided by the tutor (often the parent or teacher) then internalizes the information, using it to guide or regulate their own performance.
Shaffer (1996) gives the example of a young girl who is given her first jigsaw. Alone, she performs poorly in attempting to solve the puzzle. The father then sits with her and describes or demonstrates some basic strategies, such as finding all the corner/edge pieces and provides a couple of pieces for the child to put together herself and offers encouragement when she does so. As the child becomes more competent, the father allows the child to work more independently. According to Vygotsky, this type of social interaction involving cooperative or collaborative dialogue promotes cognitive development.
In order to gain an understanding of Vygotsky's theories on cognitive development, one must understand two of the main principles of Vygotsky's work: the More Knowledgeable Other (MKO) and the Zone of Proximal Development (ZPD).
More Knowledgeable Other
The more knowledgeable other (MKO) is somewhat self-explanatory; it refers to someone who has a better understanding or a higher ability level than the learner, with respect to a particular task, process, or concept.
Although the implication is that the MKO is a teacher or an older adult, this is not necessarily the case. Many times, a child's peers or an adult's children may be the individuals with more knowledge or experience. For example, who is more likely to know more about the newest teenage music groups, how to win at the most recent PlayStation game, or how to correctly perform the newest dance craze - a child or their parents?
In fact, theMKO need not be a person at all. Some companies, to support employees in their learning process, are now using electronic performance support systems. Electronic tutors have also been used in educational settings to facilitate and guide students through the learning process. The key to MKOs is that they must have (or be programmed with) more knowledge about the topic being learned than the learner does.
Zone of Proximal Development
The concept of the More Knowledgeable Other is integrally related to the second important principle of Vygotsky's work, the Zone of Proximal Development.
This is an important concept that relates to the difference between what a child can achieve independently and what a child can achieve with guidance and encouragement from a skilled partner.
For example, the child could not solve the jigsaw puzzle (in the example above) by itself and would have taken a long time to do so (if at all), but was able to solve it following interaction with the father, and has developed competence at this skill that will be applied to future jigsaws.
Vygotsky (1978) sees the Zone of Proximal Development as the area where the most sensitive instruction or guidance should be given - allowing the child to develop skills they will then use on their own - developing higher mental functions.
Vygotsky also views interaction with peers as an effective way of developing skills and strategies. He suggests that teachers use cooperative learning exercises where less competent children develop with help from more skillful peers - within the zone of proximal development.
Evidence for Vygotsky and the ZPD
Freund (1990) conducted a study in which children had to decide which items of furniture should be placed in particular areas of a dolls house. Some children were allowed to play with their mother in a similar situation before they attempted it alone (zone of proximal development) whilst others were allowed to work on this by themselves (Piaget's discovery learning).
Freund found that those who had previously worked with their mother (ZPD) showed greatest improvement compared with their first attempt at the task. The conclusion being that guided learning within theZPD led to greater understanding/performance than working alone (discovery learning).
Vygotsky and Language
Vygotsky believed that language develops from social interactions, for communication purposes. Vygotsky viewed language as man's greatest tool, a means for communicating with the outside world.
According to Vygotsky (1962) language plays 2 critical roles in cognitive development:
1: It is the main means by which adults transmit information to children.
2: Language itself becomes a very powerful tool of intellectual adaptation.
Vygotsky (1987) differentiates between three forms of language: social speech which is external communication used to talk to others (typical from the age of two); private speech (typical from the age of three) which is directed to the self and serves an intellectual function; and finally private speech goes underground, diminishing in audibility as it takes on a self-regulating function and is transformed into silent inner speech (typical from the age of seven).
For Vygotsky, thought and language are initially separate systems from the beginning of life, merging at around three years of age. At this point speech and thought become interdependent: thought becomes verbal, speech becomes representational. When this happens, children's monologues internalized to become inner speech. The internalization of language is important as it drives cognitive development.
"Inner speech is not the interior aspect of external speech - it is a function in itself. It still remains speech, i.e. thought connected with words. But while in external speech thought is embodied in words, in inner speech words dies as they bring forth thought. Inner speech is to a large extent thinking in pure meanings" (Vygotsky, 1962: p. 149).
Vygotsky (1987) was the first psychologist to document the importance of private speech. He considered private speech as the transition point between social and inner speech, the moment in development where language and thought unite to constitute verbal thinking. Thus private speech, in Vygotsky's view, was the earliest manifestation of inner speech. Indeed, private speech is more similar (in its form and function) to inner speech than social speech.
Private speech is "typically defined, in contrast to social speech, as speech addressed to the self (not to others) for the purpose of self-regulation (rather than communication)" (Diaz, 1992, p.62). Unlike inner speech which is covert (i.e. hidden), private speech is overt.
In contrast to Piaget's (1959) notion of private speech representing a developmental dead-end, Vygotsky (1934, 1987) viewed private speech as: "a revolution in development which is triggered when preverbal thought and preintellectual language come together to create fundamentally new forms of mental functioning" (Fernyhough & Fradley, 2005: p. 1).
In addition to disagreeing on the functional significance of private speech, Vygotsky and Piaget also offered opposing views on the developmental course of private speech and the environmental circumstances in which it occurs most often (Berk & Garvin, 1984).
Through private speech, children begin to collaborate with themselves in the same way a more knowledgeable other (e.g. adults) collaborate with them in the achievement of a given function.
Vygotsky sees "private speech" as a means for children to plan activities and strategies and therefore aid their development. Private speech is the use of language for self-regulation of behavior. Language is therefore an accelerator to thinking/understanding (Jerome Bruner also views language in this way). Vygotsky believed that children who engaged in large amounts of private speech are more socially competent than children who do not use it extensively.
Vygotsky (1987) notes that private speech does not merely accompany a child's activity but acts as a tool used by the developing child to facilitate cognitive processes, such as overcoming task obstacles, enhancing imagination, thinking, and conscious awareness. Children use private speech most often during intermediate difficulty tasks because they are attempting to self-regulate by verbally planning and organizing their thoughts (Winsler et al., 2007).
The frequency and content of private speech are then correlated with behavior or performance. For example, private speech appears to be functionally related to cognitive performance: It appears at times of difficulty with a task. For example, tasks related to executive function (Fernyhough & Fradley, 2005), problem solving tasks (Behrend et al., 1992), schoolwork in both language (Berk & Landau, 1993), and mathematics (Ostad & Sorensen, 2007).
Berk (1986) provided empirical support for the notion of private speech. He found that most private speech exhibited by children serves to describe or guide the child's actions.
Berk also discovered than child engaged in private speech more often when working alone on challenging tasks and also when their teacher was not immediately available to help them. Furthermore, Berk also found that private speech develops similarly in all children regardless of cultural background.
Vygotsky (1987) proposed that private speech is a product of an individual's social environment. This hypothesis is supported by the fact that there exist high positive correlations between rates of social interaction and private speech in children.
Children raised in cognitively and linguistically stimulating environments (situations more frequently observed in higher socioeconomic status families) start using and internalizing private speech faster than children from less privileged backgrounds. Indeed, children raised in environments characterized by low verbal and social exchanges exhibit delays in private speech development.
Childrens' use of private speech diminishes as they grow older and follows a curvilinear trend. This is due to changes in ontogenetic development whereby children are able to internalize language (through inner speech) in order to self-regulate their behavior (Vygotsky, 1987). For example, research has shown that childrens' private speech usually peaks at 3–4 years of age, decreases at 6–7 years of age, and gradually fades out to be mostly internalized by age 10 (Diaz, 1992).
Vygotsky proposed that private speech diminishes and disappears with age not because it becomes socialized, as Piaget suggested, but rather because it goes underground to constitute inner speech or verbal thought" (Frauenglass & Diaz, 1985).
Classroom Applications
A contemporary educational application of Vygotsky's theories is "reciprocal teaching", used to improve students' ability to learn from text. In this method, teacher and students collaborate in learning and practicing four key skills: summarizing, questioning, clarifying, and predicting. The teacher's role in the process is reduced over time.
Also, Vygotsky is relevant to instructional concepts such as "scaffolding" and "apprenticeship", in which a teacher or more advanced peer helps to structure or arrange a task so that a novice can work on it successfully.
Vygotsky's theories also feed into current interest in collaborative learning, suggesting that group members should have different levels of ability so more advanced peers can help less advanced members operate within their ZPD.
Critical Evaluation
Vygotsky's work has not received same level of intense scrutiny that Piaget's has, partly due to the time consuming process of translating Vygotsky's work from Russian. Also, Vygotsky's sociocultural perspective does not provide as many specific hypotheses to test as did Piaget's theory, making refutation difficult, if not impossible.
Perhaps the main criticism of Vygotsky's work concerns the assumption that it is relevant to all cultures. Rogoff (1990) dismisses the idea that Vygotsky's ideas are culturally universal and instead states the concept of scaffolding - which is heavily dependent on verbal instruction - may not be equally useful in all cultures for all types of learning. Indeed, in some instances observation and practice may be more effective ways of learning certain skills.
