Correct Response: C. By offering English learners a variety of supplies, tools, manipulatives, and graphic organizers, the teacher demonstrates awareness that English learners may differ in the ways that they navigate a learning environment and perceive and comprehend information, and that they may have different ways of approaching academic content and tasks. Some English learners may explain themselves well in writing but not in speech; others may use outlines, illustrations, labeling, or demonstrations with manipulatives to show understanding. By encouraging English learners to show the problem-solving steps they use in algebra and geometry activities via class supplies and/or through speaking, writing, or drawing, the teacher demonstrates awareness of the importance of providing students with multiple means of exhibiting their knowledge or skills during informal, formative assessments. The options involving drawings and manipulatives provide the additional benefit of allowing students with very limited English language proficiency to demonstrate their understanding nonverbally. A is incorrect because, although the means of assessment described in the scenario provide flexibility, they do not permit students to establish their own pace for learning while receiving ongoing feedback. B is incorrect because Total Physical Response (TPR) is a teaching and learning method involving the coordination of students' speech and physical actions; the item scenario does not describe incorporating TPR principles into authentic assessment of students' content-area skills. D is incorrect because, in this item scenario, there is no modeling of assessment strategies that students can use in self-monitoring their discipline-specific academic language development.
