Correct Response: B: Providing English learners with a vocabulary and concept overview prior to reading a new text helps activate students' schema related to the text's content. The overview provides the teacher with the opportunity to explain academic language and content that may be conceptually unfamiliar to the students, thus preparing them to access the material covered by the text. A and C provide extension opportunities to further students' interests but do not promote their comprehension, help them monitor for understanding, or activate schema. D provides students with a strategy for supporting their independent comprehension-monitoring skills but does not scaffold content learning or build academic language to support reading comprehension.
