This is a qualitative case study of two students' composing processes as they developed a documentary video about the Dominican Republic in an urban, public middle school classroom. While using a digital video editing program, the students moved across multiple media (the Web, digital video, books, and writing), drawing semiotic resources from each as they did so. Using sociosemiotic and dialogic-intertextual theoretical frameworks, the author examines how the interface of the video editing program influenced the students' composing by making new types of semiotic resources available and new means of combining these resources. As they moved across these media in a nonlinear fashion, the students created an interactive context for composing that transcended the individual possibilities of each respective medium. This suggests that multimedial composing environments offer a rich intertextual landscape and unique ways of making meanings.

This case study closely examines how John (a former student of mine, age eight, second grade)composed during an informal writing group at school. Using qualitative research methods, I found that John selectively took up conventions, characters, story grammars, themes, and motifs from video games, television, Web pages, and comics.
