Within the research project ”Genres in Transition – Aesthetic Writing Practices in Upper Secondary School” (carried through in cooperation with Per-Olof Erixon, Umeå university, Sweden) changing conditions for “capabilities for communicative action” in the media ecology of media culture have been studied. As a way to document media habits and media use among 17-year-old students in a media program in a Swedish upper secondary school, the students were asked to produce “media diaries” using multimedia software. The paper will be focused on relationships between and within verbal texts, images and music in one of the productions. The analysis aims to show how different semiotic resources/modalities are put into play and how these are means for identity formation. Basic concepts for analysis and interpretation are remediation, immediacy and hypermediacy, archive and narrative. The analysis and interpretation will result in a discussion of “media reflexivity” as a creative capability for communicative action.
