Recent research indicates that the methodology for teaching English language learners (ELLs) is unique. One approach most commonly used to teach this group in the United States is referred to as sheltered instruction. With Sheltered English Immersion (SEI), middle school teachers simultaneously teach content and language skills. The author will explore how to integrate manipulatives and technology into a lesson that incorporates major components of Structured English Immersion. An effective SEI teacher incorporates listening, speaking, reading, and writing in mathematics content and language instruction. The lesson described here demonstrates SEI components while using technology. The components of effective SEI practices in this article come directly from the Structured Instruction Observation Protocol designed by Echevarria, Vogt, and Short. Using technology in instruction is a way to transition ELLs to the mainstream curriculum. (Contains 5 figures.)
