Without limits or boundaries

The Ibero-American Association of Higher Distance Education (AIESAD) is committed to the organization of meetings and gatherings of Ibero-American experts and academic authorities, as well as all those activities that strengthen the necessary solidarity of the Ibero-American peoples and the enhancement of the common culture within its own purposes. It is in this context that we present these proceedings of the XX Regional Meeting of AIESAD to the entire Ibero-American academic and scientific community with the theme "Without limits or borders: new challenges of higher education in the global digital era", organized by the Universidad Nacional de Educación a Distancia of Spain (UNED), at the end of its 50th anniversary, in collaboration with the UNESCO Chair of Distance Education of the UNED and the Universidad Nacional Abierta y a Distancia of Colombia (UNAD). The meeting took place on September 27, 28 and 29, 2023 at the Faculty of Education of the UNED, in Madrid, in hybrid mode.
