Which type of reading materials would most effectively support academic vocabulary development for ESL learners?

Choosing fiction and nonfiction books on high-interest topics is particularly effective for supporting academic vocabulary development among ESL learners because these materials not only engage students but also present them with a variety of language contexts. High-interest topics can stimulate curiosity, making it more likely that learners will encounter and want to understand new vocabulary. These texts often integrate essential vocabulary within relatable narratives or informative content, facilitating both comprehension and retention.

Additionally, fiction can expand learners' understanding of nuanced language through character development and dialogues, while nonfiction can present specific academic language relevant to various fields of study. This diverse exposure encourages students to practice and apply new vocabulary in different contexts, reinforcing their learning.

Other materials, such as classical literature or advanced magazines, may present linguistic challenges that could overwhelm learners rather than inspire them. Textbooks, while informative, often lack the narrative context and engagement found in fiction and nonfiction, which can limit vocabulary acquisition and practical use. Thus, high-interest books create a balanced approach to learning, combining engagement with the exposure to academic vocabulary necessary for success in various educational settings.
