This Element offers readers an overview of the theory, research, and practice of teaching academic writing to second language/multilingual (L2) students. The Element begins with a discussion of contextual features and some of the most common settings in which L2AW is taught. The Element then defines and shares examples of several concepts, pedagogical approaches, and teaching practices that are particularly relevant to L2AW instruction. Reflective questions guide readers to consider how these aspects of L2AW might be carried out within their own educational settings. Finally, the Element considers the rapid changes in technology and their influences on texts and academic writing.
