In order to effectively write any type of text, a writer has to have a focus on the intended audience. This awareness affects not only the style of writing to use, but also helps to achieve the purpose of the text. This is an important concept for all students, but particularly for EAP and ESP students because in their academic and professional careers they will be writing and presenting to a wide range of audiences. This presentation will first give a short overview of the importance of understanding the notion of audience, and then I will share activities that participants can use in their courses to both help their students notice aspects of audience in the texts they read, as well as how to incorporate them into their own academic and professional writing.
