English language learners (ELLs) are expected to meet standards in a second language, and their proficiency in English directly impacts their ability to meet these standards. The comprehension of text throughout the stages of English language acquisition requires scaffolds such as adapted text, translations, native language support, cognates, summaries, pictures, realia, glossaries, bilingual dictionaries, thesauri, and other modes of comprehensible input. Strategic use of the student's first language is important to ensure linguistic, affective, cognitive, and academic development in English. ELLs can and should be encouraged to use knowledge of their first language to enhance vocabulary development; vocabulary needs to be in the context of connected oral and written discourse so that it is meaningful.
