The SIOP Model is a research-based approach to sheltered instruction that has proven effective in addressing the academic needs of English language learners throughout the United States. The model consists of eight components:
Using instructional strategies linked to these components, content area teachers help English learners develop their academic English skills as they learn grade-level content. Training in the SIOP Model helps teachers plan and deliver lessons that incorporate these strategies consistently.
The SIOP Model was developed in a national research project conducted from 1996 to 2003, sponsored by the Center for Research on Education, Diversity & Excellence (CREDE). Through literature review and with the collaboration of practicing teachers, researchers identified instructional features of high-quality sheltered lessons. The model was refined over several years of field testing
Early research found the SIOP Model to be effective with ELLs as measured by narrative and expository writing assessments. CAL is currently conducting further research in elementary and secondary schools by facilitating professional development on the SIOP Model and examining the effects of SIOP-based instruction on student achievement in core content areas and in English language development.

With funding from the Carnegie Corporation of New York and the Rockefeller Foundation, CAL is conducting research on the SIOP Model in two New Jersey school districts. Research activities involve professional development with 70 junior and senior high English, science, math, and social studies teachers.
Under the Center for Research on the Educational Achievement and Teaching of English Language Learners (CREATE) funded by the U.S. Department of Education, CAL is investigating the impact of the SIOP Model on student academic achievement in science, a subject area with high language demands.
Under the Success Through Academic Interventions in Language and Literacy (SAILL) project funded by the U.S. Department of Education, CAL is investigating the impact of the SIOP Model on the math performance of Spanish-speaking English language learners in structured English immersion and transitional bilingual K-3 math classrooms. The goal of the project is to develop programs that optimize language learning in both kinds of classrooms.
With funding from The James Irvine Foundation, CAL is conducting research on a program that supports high school and post-secondary school success for language minority students. Content teachers are implementing the SIOP Model in three high schools.

In "Teacher Skills to Support English Language Learners,” SIOP Model co-developers Deborah Short and Jana Echevarria discuss the connection between characteristics of English language learners and the components of the SIOP Model. They stress that because most English language learners receive instruction in content-area classes, teachers of these classes need to understand the varying backgrounds of ELLs and their different levels of conversational and academic English skills.
Voices of Vision
An episode of "Voices of Vision" profiling CAL highlights The Georgia Project, for which CAL has conducted a needs assessment and sustained professional development on research-based sheltered instruction to English Language Learners. "Attitudes of Dalton's parents, students, and teachers have been transformed by CAL's work," says the documentary about CAL's work in one Georgia community.
