Despite the emerging academic instruction for students
with moderate to severe intellectual disability, the current
literature is limited by instructional strategies employed
(e.g., time delay, system of least prompts) and breadth of
science content taught (Courtade et al., 2007). This study
was designed to address these limitations by using SLs
embedding systematic instruction combined with guided
notes to enhance science learning across three units of science,
which incorporated multiple standards of Earth and
Space Science, Life Science, Physical Science, and Science
as Inquiry, for students with moderate to severe intellectual
disability. Specifically, the purpose of this study was to
examine the effects of SLs alone and in combination with
guided notes during science instruction on science quiz
scores of three elementary students with moderate to severe
intellectual disability and autism.
