ELL meaning in Academic & Science ?

English-Language Learner (often abbreviated as ELL) is a term used in some English-speaking countries such as the US and Canada to describe a person who is learning the English language and has a native language that is not English. Some educational advocates, especially in the United States, classify theses students as non-native English speakers or emergent bilinguals. Various other terms are also used to refer to students who are not proficient in English, such as English as a Second Language (ESL), English as an Additional Language (EAL), limited English proficient (LEP), Culturally and Linguistically Diverse (CLD), non-native English speaker, bilingual students, heritage language, emergent bilingual, and language-minority students. The legal term that is used in federal legislation is 'limited English proficient'. The instruction and assessment of students, their cultural background, and the attitudes of classroom teachers towards ELLs have all been found to be factors in the achievement of these students. Several methods have been suggested to effectively teach ELLs, including integrating their home cultures into the classroom, involving them in language-appropriate content-area instruction early on, and integrating literature into their learning programs.
