This report summarizes the characteristics of the literature and implications for practice and future research…

This study measured the effect of an evidence-based science curriculum delivered in both English and Spanish using the preview-view-review (PVR) strategy, on the science vocabulary and content knowledge acquired by students with moderate to severe intellectual disabilities who were learning English. The intervention was compared to the same…

This study examined the effects of an intervention that integrated peer-mediated instruction (PMI) with augmentative and alternative communication (AAC) using speech-generating devices (SGDs). Nine trained peer tutors without disabilities taught science concepts and modeled use of SGDs following a script to three elementary school students with…

This chapter reviews the intervention research literature -- particularly interventions deemed evidence-based -- for students with intellectual disability across academic and life-skills instruction. Although the focus of this chapter is the spectrum of students covered under the term "intellectual disability," the majority of research…

Successful text comprehension is a complex task, requiring a variety of cognitive skills and processes that support students in making inferences, integrating information across sentences in text, monitoring understanding, and gaining knowledge about text structure.
