Activity theory has long been an influential framework in the field of education. However, its theoretical concepts are not easily grasped by scholars, mainly due to difficulties in translation from the original Russian works, the complexity of these concepts and multiple versions embedded within the tradition. The two major approaches within activity theory were established by Leontiev and another version proposed later by Engeström, and they have often been confused and conflated together in the literature. This paper provides a much-needed theoretical comparison between these approaches in regard to the field of education. The criteria for comparison involve their theoretical foundations, central phenomena of interest, key theoretical concepts, units of analysis and explanatory mechanisms. Insights from this paper contribute to establishing a more refined understanding of activity theory and its variants, which in turn allows researchers to make more informed decisions when selecting and using these frameworks. Implications for practical research practices are discussed with examples from the area of teacher professional development.

At the social turn in education, Vygotsky's cultural-historical/sociocultural theory (VST) has become particularly influential. There are other cultural-historical traditions associated with VST, including Leontiev's and Engeström's versions of cultural-historical activity theory (CHAT). These approaches are frequently conflated, resulting in confusion that can be consequential in interpreting educational research findings. Unravelling these frameworks is thus an important and urgent task. In addressing this gap, the paper first provides an overview of the origins and fundamental tenets of these cultural-historical perspectives, followed by a critical evaluation of and comparison among them. Implications for utilising these cultural-historical traditions are discussed.

In recent decades, Vygotsky’s sociocultural theory (VST) has become particularly influential in the fields of education and educational psychology. Perezhivanie is an important concept in VST that stipulates a relative influence of environment on a person’s psychological development depending on their age or stage of development. However, perezhivanie has been differentially interpreted and applied in previous literature to suit the purposes of domain-specific research. The lack of a comprehensive theoretical understanding of the concept can undermine research findings and their implications for educational practices. Drawing on a content analysis of Vygotsky’s key texts on perezhivanie, this paper provides a much-needed theoretical discussion that unpacks comprehensively the theoretical content of perezhivanie and the methodological principles guiding its application. The findings revealed that conceptually, perezhivanie can be defined as: (a) a theoretical relation between an individual and their environment, (b) an abstract experience of or attitude towards a life situation and (c) a concrete lived experience of an event within that situation. Four major discernible components of an individual’s perezhivanie include the environmental factor, personal characteristics mobilised, refraction prism and psychological influences. Five key methodological principles were conceived to assist the employment of perezhivanie in educational/psychological research: (1) utilising a perezhivanie as a unit of analysis, (2) analysing perezhivanie at different levels, (3) accounting for the perspective of the individual involved, (4) constructing the refraction prism and (5) determining the major personal characteristics mobilised in the perezhivanie. Implications for educational and research practices are then discussed.
