Correct Response: B. Preteaching key vocabulary and prerequisite concepts based on students' needs and engaging students in pre- and postreading activities are research-based best practices that scaffold English language learners' understanding of new content by supporting their academic language development related to a given unit. Research also suggests that oral- and written-language activities, such as the postreading discussions and the dialogue journal activity described in this scenario, play an important role in building and reinforcing academic language. A is incorrect because the scenario does not state or imply that the teachers provided structured models of academic discourse during the unit. C is incorrect because, while some of the activities may support the students' development of oracy, the goal of the activities is content development through integrated use of listening, speaking, reading, and writing. D is incorrect because the scenario does not suggest that a primary focus of the unit is to promote self-monitoring skills.
