Correct Response: C. Explicit instruction in common Greek and Latin roots and affixes helps students learn to recognize the individual morphemes that make up morphologically complex, multisyllable words. Thus, by learning these common roots and affixes, students can use their understanding of morphology (word formation) to help them determine the meanings of many multisyllable words in English. A is incorrect because instruction in common Greek and Latin roots and affixes supports students' learning of new words and does not relate to the use of common textual features, such as captions and subtitles. B is incorrect because, although students may gain an appreciation of the origins of content-area words by studying Greek and Latin roots and affixes, the strategy is most beneficial for helping students determine the meaning of unknown academic words. Finally, D is incorrect because the scenario focuses on a specific word-learning strategy, whereas word consciousness relates to having a positive attitude toward words—having a strong interest in learning about words and in acquiring new words. The scenario does not focus on the development of these affective factors.
