Book excerpt: Multimodality in Writing attempts to generate and apply new theories, disciplines and methods to account for semiotic processes in texts and during text production. It thus showcases new directions in multimodal research and theorizing writing practices from a multimodal perspective. It explores texts, producers of texts, and readers of texts. It also focuses on teaching multimodal text production and writing pedagogy from different domains and disciplines, such as rhetoric and writing composition, architecture, mathematics, film-making, science and the newsroom. Multimodality in Writing explores the kinds of methodological approaches that can augment social semiotic approaches to analyzing and teaching writing, including rhetoric, Systemic Functional Linguistics, ethnographic approaches, and genre pedagogy. Much of the research shows how the regularities of modes and interest of sign makers are socially shaped to realize convention. Because of this, the approaches are strongly underpinned by social and cultural theories of representation and communication.
