Final answer:
ELs often benefit from visual aids, may lack exposure to academic language, and have different native language structures, which can influence their English language acquisition.
Step-by-step explanation:
English Language Learners' (ELs) need for vocabulary instruction may differ from native speakers due to a variety of reasons. Firstly, visual aids can be especially beneficial for ELs as they provide contextual clues that enhance understanding. Secondly, ELs may lack exposure to academic language, which can impede their ability to fully grasp complex educational concepts. Lastly, the structure of their native language can influence the way they learn English, often requiring different instructional strategies to accommodate for these structural differences. However, it is a misconception that ELs often excel in written assessments without additional support and instruction, as they may face challenges with English grammar, vocabulary, and conventions.
