Answering questions and solving problems are critical skills that affect the quality of life for all people. The content areas of science and engineering traditionally and most directly address the processes of inquiry and problem-solving. While there is an increasing body of research surrounding teaching academic content (i.e., mathematics and…

For students with moderate and severe intellectual disability (ID), reading instruction has focused on teaching sight words. However, research supports a shift in focusing instruction on reading skills such as phonemic awareness, phonics, and fluency. The purpose of this systematic literature review was to focus on the research completed with…

The purpose of the study was to compare the differential effects of response independent and response-dependent criteria used to determine when to increase to the next delay interval in the progressive time delay (PTD) procedure. An adapted alternating treatments design was used to evaluate the relative efficiency of three variations of the PTD…

Across the United States, State Education Agencies (SEAs) are using tiered strategies, such as Multi-Tiered System of Supports (MTSS) frameworks, to ensure that all students, including diverse learners, receive equal, high-quality education. However, little is known about the extent to which SEAs are encouraging use of MTSS to address the needs of…

Artificial intelligence (AI) has transformative potential to support the education of students with moderate to severe intellectual disabilities (M/SID) and their teachers. Although research and evidence-based practices (EBPs) are integral to fostering positive student learning outcomes, educators face challenges in effectively implementing these…

Modified schema-based instruction (MSBI) is a strategy to teach mathematical word problem solving to students with moderate and severe disabilities (MSD). In this comprehensive review, we explore the current state of research on MSBI to determine whether MSBI is an evidence-based practice (EBP) for students with MSD. We reviewed 12 studies, of…

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 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…

School psychologists are well-positioned to assist practitioners in engaging students in physical activity (PA) which can increase student access to improved well-being and associated health benefits. This may be of particular importance for adolescents with moderate to severe developmental disabilities (DD; autism and intellectual disability) who…

This study used a single-subject alternating treatment design across students to compare mass discrete trials and distributed mass trials distributed in a shared story reading on the acquisition of functional skills for students with Autism. The results of this study examined a functional relationship between the interventions on the acquisition…

The purpose of the study was to evaluate the effects of a system of least prompts procedure and use of a graphic organizer to teach the academic literacy standard of comparing characters in text for elementary students with moderate and severe intellectual disability. A multiple probe across participants design was used to evaluate the results.…

Students with significant intellectual and developmental disabilities deserve access to instruction on academic skills in addition to functional skills. Many teachers, however, report challenges with identifying appropriate evidence-based practices to teach academics to these students. The purpose of this systematic review was to summarize and…

This study investigated the relation between grade level, support needs, and use of augmentative and alternative communication (AAC) and the participation of secondary age students with intellectual disability in school-sponsored extracurricular activities. Participants were special education teachers with at least one student with an intellectual…

This social validity study accompanied a 9-month randomized control trial that investigated the efficacy of an emergent literacy program, Early Literacy Skills Builder (ELSB), delivered in general education elementary classrooms to students with severe disabilities, including autism. The social validity research questions focused on (a) the social…

Small group instruction in classrooms provides children opportunities to collaborate on academic tasks, as well as opportunities for social interactions. Although such arrangements are common for children with typical development, children with moderate to severe disabilities (MSD) may receive few or no opportunities to participate meaningfully in…
