What is SIOP

The increased number of English learners (EL) in mainstream classrooms in the United States necessitates the use of effective strategies to support ELs' learning. Previous studies have shown that the sheltered instruction observation protocol (SIOP) model is effective in teaching content subjects to EL students. In this chapter, the SIOP model has been incorporated to teach a science unit to students of level-3 English proficiency. This chapter includes an introduction, literature review, unit about plants, and conclusion. The unit has 10 lessons with several features of the SIOP model to serve as an example for mainstream classroom teachers. Features used in this unit include visuals, graphic organizers, vocabulary previews, hands-on activities, video clips, charts, rubrics, and different forms of assessment. If implemented, the SIOP model can be a tool for classroom teachers in making content knowledge accessible to EL students and help them succeed in their learning.
