This paper brings to light the essence, characteristics, and role of educational-cognitive barriers in the preparation of college-attending future social pedagogues that may arise in the process of their mastering social-pedagogical skills related to the prevention of social dependencies. The authors share the findings of their study of a typology of such obstacles in the educational process. Special attention is devoted to typical educational situations in the preparation of students (e.g., getting engaged in methodological activity related to preventing social dependencies, testing mastered methodological schemes and algorithms in activity related to preventing social dependencies, and discovering methodological knowledge) and specific educational-cognitive barriers dominating these situations.
