<p>The article is dedicated to the memory of the author's teachers in psychology, written in connection with the anniversaries of the outstanding Russian psychologists P.Ya. Galperin and N.G. Alekseev. Both scientists are the authors of the ideas underlying the reflective&ndash;activity approach (RAA) to assist students in overcoming learning difficulties, developed by the author. In 2022, practicians of the RAA celebrate 25 years since the birth of the approach, and this event prompts the author to turn to the origins of its occurrence, to the ideas on the basis of which the RAA technology is built. P.Ya. Galperin's ideas on internalization and the formation of mental actions are combined with N.G. Alekseev's ideas on reflection and reflective thinking based on the basic principles of cultural&ndash;historical psychology developed by L.S. Vygotskii. As a basis for uniting the ideas of L.S. Vygotskii, P.Ya. Galperin and N.G. Alekseev, their attitude to psychological practice becomes. The implementation of these ideas within the framework of the RAA is briefly considered on the example of three projects: summer schools, chess for general development, assistance to orphans with disabilities and severe somatic diseases.</p>
