Correct Response: B. By reading aloud a picture book that is set in a rain forest at the beginning of the unit, the teacher provides an opportunity for students to develop valuable schema related to new vocabulary and concepts that will be studied in the unit. A is incorrect because the teacher does not model cognitive strategies during the read-aloud and the students are not asked to use cognitive learning strategies. C is incorrect because, although the read-aloud provides students with a context- embedded introduction to new vocabulary, the read-aloud in itself merely introduces new vocabulary but does not provide students with explicit instruction in academic language. Finally, since the book is a work of literature and not an informational text, the read-aloud is not likely to expose the students to content-specific language structures, making D incorrect.
