The concept of the zone of proximal development (ZPD) emerged in the cultural-historical theory of Vygotsky as a result of the broader quest for a new psychology and forms of education in the post-revolutionary Soviet Union. The project of unprecedented socioeconomic transformations created a political demand for education that would build intellectual, physical, and moral capabilities of the new generation of young people. Cultural-historical psychology, at that point in time, emerged as a result of such a demand, investigating the development of psychological functions and the role of education and upbringing in mediating this process. This meant an advancement of the study of mental activity as embedded in social and cultural practices where any intellectual function appears, first, on the social plane and then on the psychological plane of the child. The concept of the ZPD was formed as a result of this genetic law of psychological development that laid a methodological foundation of the new psychology.
In terms of developing this foundation, Vygotsky was among the first psychologists to apply the principles of dialectics, searching for a fundamentally new approach to the analysis and explanation of psychological phenomena, especially their causal-dynamic nature. The concept of the ZPD is illustrative of Vygotsky’s dialectical method insofar as it represents the development of the child as a unity of contradictory relations between her actual level of development and the potential level that the child can achieve in collaboration with others. Initially, Vygotsky introduced the ZPD as a diagnostic principle of defining the child’s abilities to collaborate with others in order to determine the area of evolving and future intellectual functions, rather than evaluating the outcomes of the child’s past development. By prioritizing the role of collaboration in the development of intellectual functions, Vygotsky’s ZPD bridged the world of psychological development and the world of education.
The ZPD, from this perspective, opens up the internal relation between development and education, with the process of education leading the development of intellectual functions. Education creates opportunities for children to build their future capabilities, wakening up, as it were, those processes that could not be possible without their participation in intersubjective encounters or dialogical classroom events. The ZPD, in a pedagogical sense, is a social space of learning and communication in which children can build their consciousness, understandings, self-regulation, and agency. Yet, this is also a space where children’s differences and particularities are most visible. Depending on how diversity is recognized, the process of education can either stimulate or repress intellectual development.
