Reflecting the digital turn in composition studies, multimedia writing courses have become commonplace in many writing programs. Yet these technology-rich courses take on new significance when located within a rhetorically based writing major, especially as a core course.

Specifically, we see the course as an opportunity to make its practices and key concept, "writing environment," more central to the major, and the writing program as a whole. Teaching writing in electronic environments also means encouraging our students to conceive of better spaces for the kinds of digital writing that they--and others--might eventually want to practice.
