What aspect does vocabulary development emphasize in literacy education?

Vocabulary development plays a crucial role in literacy education as it emphasizes understanding and utilizing new words within context. This aspect is essential because it encourages students not only to learn new vocabulary but also to integrate these words into their reading and writing practices. When students understand how to use words in various contexts, they enhance their comprehension skills and are able to express their ideas more clearly, thereby deepening their overall literacy. This process often involves activities such as reading diverse texts, engaging in discussions, and using new vocabulary in writing, which reinforces learning.

Focusing solely on comprehension tests or memorizing definitions without application does not foster a comprehensive understanding of vocabulary. Similarly, reanalyzing previous materials, while it has its own merits in education, does not specifically target the active development of vocabulary through contextual understanding and application that is seen in choice B.
