Sheltered English instruction is an instructional approach that engages English Language Learners (ELLs) above the beginner level in developing grade-level content-area knowledge, academic skills, and increased English proficiency. In sheltered English classes, teachers use clear, direct, simple English and a wide range of scaffolding strategies to communicate meaningful input in the content area to students. Learning activities that connect new content to students' prior knowledge, that require collaboration among students, and that spiral through curriculum material, offer ELLs the grade-level content instruction of their English-speaking peers, while adapting lesson delivery to suit their English proficiency level.
