The SIOP Model
Sheltered Instruction Observation Protocol
An excellent resource for teachers of English language learners is the book “Making Content Comprehensible for English
Learners: The SIOP Model”. The Sheltered Instruction Observation Protocol (SIOP) is an instructional model
of sheltered instruction, second language acquisition, and English language development. Sheltered instruction is a method
of making grade-level academic content understandable and comprehensible to English language learners while at the same time
promoting English language development (ELD) and literacy. ESL, mainstream and bilingual teachers would benefit from this
instructional model. The Sheltered Instruction Observation Protocol (SIOP) brings together all of the essential components
of effective sheltered instruction into one comprehensive model of instruction for English language learners.
The SIOP model consists of eight distinct SIOP components: lesson preparation,
building background, comprehensible input, strategies, interaction, practice/application, lesson delivery, and review/assessment.
Each SIOP component also contains additional features that characterize each component.
Another important feature of the book is that it contains ESL and ELD lesson plans and classroom vignettes. The ELD/ESL
This book is a “must-have” book for all teachers
