![]() Thus, the task of comparing the effectiveness of bilingual education with that of sheltered immersion is further complicated by the fact that the former is less bilingual than it has been in the past. Accordingly, teachers felt the need to prepare their students for the possibility that they could soon be in an English language classroom. ![]() Second, because the law greatly reduced the demand for bilingual classes, there was no guarantee in any specific school that a bilingual class could be assembled for the next grade in the following year. Sheltered instruction is designed to provide second language learners with the same high- quality, academically challenging content that native English speakers receive through a combination of good teaching techniques and an explicit focus on academic language development. ![]() First, the Proposition 227 vote expressed California's citizens' preference for a greater emphasis on English, and teachers believed that they should respond to the wishes of the people they served. The teachers with whom I spoke in the remaining Spanish bilingual education classes in spring 1999 said that they were using more English for instruction than they had in the past. Similarly, in Arizona in 2000 and in Massachusetts in 2002-the years in which these states mandated a switch to structured immersion-only 40 percent of English language learners at most were enrolled in bilingual education (Arizona Department of Education, 2004 Massachusetts Department of Education, personal communications, 2004).īesides moving most English language learners into sheltered immersion programs, Proposition 227 also changed the way Spanish bilingual education programs operated. Approximately 71 percent of California's English language learners participated in programs that used English as the dominant language of instruction-most of them in sink-or-swim or near-sink-or-swim situations (Rossell, 2002). ![]() In California, only about 29 percent of English language learners were enrolled in bilingual education in 1998, the year in which this approach was voted out as the default assignment for such students.

CAL has conducted research on adapting the SIOP Model for use in two-way immersion (dual language) programs. SIOP instruction also benefits students learning content through another language. In addition, teachers report that SIOP-based teaching benefits all students, not just those who are learning English as an additional language. Learn about the SIOP Model research base. Research shows that when teachers fully implement the SIOP Model, English learners' academic performance improves. Who benefits from SIOP instruction?Īs the number of English learners increases in schools across the United States, educators are seeking effective ways to help them succeed in K-12 ESL, content area, and bilingual classrooms. Using instructional strategies connected to each of these components, teachers are able to design and deliver lessons that address the academic and linguistic needs of English learners. The SIOP Model consists of eight interrelated components: The Sheltered Instruction Observation Protocol (SIOP) Model is a research-based and validated instructional model that has proven effective in addressing the academic needs of English learners throughout the United States.
