Abstract: The purpose of this study is to reconstruct the interaction of the League of Education with the pedological community, which will reveal its role in the formation of pedological experience, subsequently applied in the 20-30s of the XX century in the USSR. The subject of the study is a community created by the League of Education and implementing pedological experiments in the educational space of the beginning of the century. The author pays special attention to the results of the League of Education on the example of Petrograd. The connection between the scientific heritage of the members of the Society and the use of these materials in the later period of the existence of the pedological movement, after 1917, is revealed. The paper analyzes the projects of the League of Education on the radical transformation of the school space, taking into account social and historical aspects. The period of existence of the pedological current before 1917 has been little studied in a historical way. The same should be noted regarding the study and analysis of the activities of the League of Education. This organization is described in most sources in several general paragraphs. The novelty of the research lies in the development and analysis of archival materials related to the organization and activities of the League of Education (the study was conducted on the basis of documents of the Central State Administration of St. Petersburg, TsGIA St. Petersburg, TSGAIPD St. Petersburg). The League of Education played a significant role not only in the analytical study of the educational space, the accumulation of pedological experience, the search for leading pedagogical developments, but also in the replication of these materials. The activities of the organization and its societies were widely covered in publications. Despite the successful and productive activities, the government refused the League of Education. And this is primarily due to the political context, from which, initially, according to the Charter of the organization, members of the society had to be abstracted. The specialists in question in the study continued their work in other institutions and created the foundation of Soviet pedology.

Abstract: The subject of the study is the origin of the first experimental laboratories and their interaction with the pedagogical community. The emphasis is placed on the prerequisites and controversial points of this cooperation, which will become the basis for pedological experiments in the 20s, and the legal functioning of the new, at that time, research space is also taken into account. The object of the study is pedology as a new scientific direction. The author examines in detail such aspects of the topic as socio-economic prerequisites, formation and scientific potential of pedological experiments. Particular attention is paid to specific representatives, their professional activities, and the assessment of a new direction in the pre-revolutionary space of the Russian Empire.
The main conclusions of the study are: identification of the "artificiality" of the new trend, generalization of the experience gained, analysis of the assessment of the first successes of the laboratories, the significance of the work of the first pedological laboratory of A. P. Nechaev in St. Petersburg, comparison of the general course of development of the experimental science of pedology with European analogues. A special contribution of the author to the study of the topic is the reconstruction of the mental space of interaction between teachers and leading specialists in the field of pedological experiments, involving archival documents of the Central State Administration of St. Petersburg regarding the history of the first pedological studio in St. Petersburg. The study attempts to trace the scientific path of the dissemination of pedagogical ideas of the new paradigm. The novelty of the study is to identify real changes in the pedagogical community of the early 20th century.
