This lesson provides models for how to teach the use of articles to secondary students who are non-native speakers of English. More specifically, the lesson focuses on helping teacher candidates develop a solid understanding of the use of definite and indefinite articles. Thus, the goal of the lesson is twofold: (1) to help teacher candidates who struggle with grammar improve their own language skills and (2) to enhance the skills of all teacher candidates by providing their own students with effective feedback on the use of articles.
