The introduction of the Dialogical Self Theory in the field of education has not received the recognition it deserves. In this article we intend to prove the importance of research in DST, reviewing its main contributions to the psychology of education for the past decade. To this end, we have organized it into three thematic areas: dialogical teaching and learning processes, professional identity in different educational levels, and studies pertaining to inclusive education and, particularly, intercultural education. We conclude with a section dedicated to future lines of research, in line with the most recent international reports on twenty-first-century education. After this review, we can state that DST constitutes a revolutionary epistemological approach, which permeabilizes the boundaries between the inter- and the intra-psychological, taking the mental and public planes as two parallel societies in constant dialogue, and and giving back to psychology its central function in the study of mental dynamics, that 'black box' which socio-constructivist trends had partially omitted.
