Nota del editor: Oportunidades y desafíos para la alfabetización mediática informacional

In the new social context determined by the constant development of ICT, citizens exercise their active role through technological devices, and media literacy is presented as an agent of change in favour of a more critical, democratic and participatory society. In this special edition, six papers are presented to con-tribute to the discussion on the challenges of media literacy in the 21st century through the study of phenomena and aspects in which the use of ICT and digital media converge with the need to offer educational proposals that respond to the citizen's formative demands. The authors give deep insights into issues such as ac-cess to education and technology, playful interaction in education, learners' moti-vation in their participation, and the materialisation of these reflections into fourth level educational proposals.
