Sheltered Instruction Observation Protocol® (SIOP®)
English Language Learners

As of February 2013 no studies of Sheltered Instruction Observation Protocol® (SIOP®) were found that fell within the scope of the English Language Learners review protocol and met WWC design standards. Therefore, the WWC is unable to draw any research based conclusions about the effectiveness or ineffectiveness of Sheltered Instruction Observation Protocol® (SIOP®) to improve outcomes in this area.
The Sheltered Instruction Observation Protocol® (SIOP®) is a framework for planning and delivering instruction in content areas such as science, history, and mathematics to English language learners as well as other students. The goal of SIOP® is to help teachers integrate academic language development into their lessons, allowing students to learn and practice English as it is used in the context of school, including the vocabulary used in textbooks and lectures in each academic discipline. Using this planning framework, teachers modify the way they teach so that the language they use to explain concepts and information is comprehensible to these students. SIOP® is intended to be applicable at levels of education from pre-K through community college. The SIOP® model consists of instructional strategies that cover eight aspects of lesson design and delivery: lesson preparation, building background, comprehensible input, strategies, interaction, practice and application, lesson delivery, and review and assessment.
