The suggestions described here to adapt instruction for English Language Learners (ELLs) are based on the concept of sheltered instruction, a model of language-support methods for instruction for ELLs derived primarily through the Sheltered Instruction Observational Protocol (SIOP) developed by Jana Echevarria, Mary Ellen Vogt, and Deborah Short (2007). While the SIOP model can address various levels of English language proficiency, students at the highest level of English language proficiency, students at the highest level of proficiency will understand the objectives better than those at the earliest stages of English acquisition.
