This chapter discusses the importance of teaching academic writing skills to non-native English speaking students. It notes that the number of international students and immigrant students enrolled in U.S. colleges and universities is significant and growing. It also acknowledges the proliferation of courses, textbooks, and programs aimed at teaching academic writing to these students. However, it argues that simply applying approaches used to teach native English speakers is not effective for non-native students. Instead, extensive instruction in academic vocabulary, grammar, and discourse is essential to develop proficiency in academic writing in a second language.
