Background. A paradox is increasingly documented in contemporary international early childhood research: the pedagogical legacy of Friedrich Froebel continues to shape everyday preschool practice — through play-based methods, didactic materials, and value orientations — while its theoretical and philosophical foundations remain largely unrecognised by practitioners themselves.
Objective. To systematise contemporary international research documenting the gap between theoretical and practical dimensions of Froebel’s legacy; to characterise institutional forms of its study abroad; and to identify the specifics of the Russian context.
Sample. The theoretical analysis draws on publications from 1991–2026 addressing the reception of Froebel’s pedagogical system in preschool education practice in Germany, the United Kingdom, Ireland, Italy, Portugal, and Australia, as well as materials from the official websites of research centres and professional associations.
Methods. Comparative-historical and problem-thematic analysis of scholarly literature; the method of institutional analysis in comparing organisational forms of Froebel’s legacy study across different countries.
Results. Three mechanisms for reproducing the theory–practice gap are identified: professional socialisation (occupational mastery through practical experience), instrumental reduction (the separation of didactic material from its conceptual system), and institutional asymmetry (the influence of the presence/absence of research centres on the reflection of practice). International research centres studying Froebel’s legacy (Germany, the United Kingdom, Ireland) are systematised and compared with the Russian context.
Conclusion. The image of Froebel as a “known stranger” (Bekannter Unbekannter) accurately captures the current state of the field: his name and individual tools are widely recognised, while the coherent conceptual system behind them remains understudied. In the Russian context, the following are necessary: the inclusion of a historical-theoretical component in teacher education programmes; the development of research infrastructure; and the strengthening of the professional community with a transition to sustainable institutional forms.
