On Several Problems with the Application of P.Ya. Galperin's Classical Theory.

Background: The theoretical and applied works of Piotr Ya. Galperin have attracted the attention of scholars for more than 70 years. But what about the contemporary situation? Does the Galperin's "System of Psychology" have only historical significance, or does it deal with crucial problems of contemporary psychology?

Objective: This article explores several opportunities for applying Galperin's System of Psychology and his theory of planned stage-by-stage formation of mental actions (PSFMA) as part of the System, in current conditions.

Design: There are three main areas where the concepts of P.Ya. Galperin's System of Psychology can be applied. The first is the application of the method of planned stage-by-stage formation to studying the formation and development of human mental activity. The second is the study of the theoretical and actual process of planned stage-by-stage formation as a psychological reality. The third area is the use of the provisions of the theory in the practice of teaching.

Results: We argue that the efficacy of the provisions of the main components of Galperin's System, and especially the PSFMA, is closely related to the solution of a number of purely theoretical issues today.

Conclusion: The condition for the successful application of PSFMA principles is a harmonious combination of the basic psychological foundations of this process, taking into account the specifics of both the activity being formed, and of those socio-economic and technological parameters that create the space where such formation is carried out.
