The media landscape has radically changed in the 21st Century with the emergence of the internet and the new digital media technologies. For young people growing up in this increasingly connected and mediated world, this provides a lot of opportunities and challenges, and educators around the world have sought to investigate and understand what the best practices are for teaching children and teenagers how to navigate in this digital world in a safe, dynamic and productive manner. In this context, two fields of studies have increasingly gained attention in educational debates: ICT in Education and Media Literacy. The former is well established in many places around the globe, especially in developed countries, as schools are improving their technology structure with the acquisition of new equipment and digital devices. Media Literacy, on the other hand, still has a low status within most education systems, even in rich countries. This research project suggests that the fact that more and more students have access to the internet and digital media devices in the classroom opens an exceptional opportunity for Media Literacy Education. Young people can use the technology available to create digital media artefacts, such as video, digital magazines, animation and podcasts, and this provides both teachers and students the chance to discuss media literacy topics in the classroom. In Ireland, most schools in the country have a good technology structure to support media literacy activities in the classroom. Following this opportunity, this study aims to investigate how these digital technologies can be used to promote media literacy practices in the classroom. In order to do so, a media literacy programme was developed and delivered to secondary students. This thesis takes a qualitative approach and uses three case studies in Dublin to investigate the potentials and limitations in the use of these technologies to develop media literacy knowledge and skills. Using interviews, questionnaires, field observation and artefact analysis as methods for the investigation, this study provides some important understandings on how the new digital technologies can be used to help promote media literacy in students.
