The teaching staff of the National University of Distance Education has a multimedia communication system that includes written materials, audiovisual media, computer support and new technological resources to organize their teaching.
The didactic material in the form of a printed book, usually called Didactic Units, constitutes the fundamental instrument for studying at the UNED. They are conceived as a series of university manuals that combine the rigor of each discipline with the adaptation of the texts to the methodology of distance learning.
As a general rule, each subject has its own Didactic Units, prepared by the teaching teams in order to facilitate learning and allow the student to study independently.
