School Reform and Standards-Based Education: A Model for English-Language Learners.

ABSTRACT The authors examined a model of instruction for English-language learners (ELLs) who were learning academic English while they tried to meet content standards required by the nations education reform movement. In previous work (J. Echevarria, M. E. Vogt, & D. Short, 2000), the authors developed and validated a model of instruction (Sheltered Instruction Observation Protocol; SIOP model) for ELLs. In this study, the authors tested the model for its effects on student achievement. Findings revealed that students whose teachers implemented the SIOP model performed slightly better than did a comparison group on an expository essay writing task, which closely approximated academic assignments that ELLs must perform in standards-based classrooms.

Research on academic literacy development in sheltered instruction classrooms

This article describes an extended program of research in sheltered instruction and the effects on the academic literacy development of English language learners. It also highlights the challenges of scaling up an instructional intervention. The intervention was the Sheltered Instruction Observation Protocol (SIOP) Model, an approach that teaches subject area curriculum to students learning through a second language using techniques that make the content material accessible and also help develop the students’ second language skills. Three successive studies looked at teacher change over time and student achievement on standardized assessments and researcher-developed measures. Results of the three studies reveal that students with teachers who were trained in the SIOP Model of sheltered instruction and implemented it with fidelity performed significantly better on assessments of academic language and literacy than students with teachers who were not trained in the model. The article offers guidance for strengthening professional development for teachers so the quality of instruction they deliver to English language learners improves and the students strengthen their English language and academic outcomes.
