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…

A growing body of literature supports the effectiveness of Modified Schema-Based Instruction (MSBI) to improve mathematical problem-solving for students with autism spectrum disorder (ASD) and intellectual disability (ID). MSBI is an intervention package that teaches students to identify the problem structure and use a problem-solving heuristic to…

Treatment intensity is an aspect of communication intervention that has received limited empirical attention. In this article, we discuss key parameters of treatment intensity related to individuals with complex communication needs who use augmentative and alternative communication. We advocate for an examination of treatment intensity along with…

In 2008, Browder and colleagues published a meta-analysis on mathematics instruction for learners with significant cognitive disabilities and found that most skills taught to these students were only from two of the five strands recommended by the National Council for Teachers of Mathematics (i.e., Number and Operations, and Measurement). A review…

Research is needed to better understand the academic instruction needs of students with significant cognitive disabilities who are English learners and the classroom practices of their teachers. In this qualitative study, we interviewed 10 teachers to learn how they identify and meet the unique needs of this student subpopulation. Our findings…

Although a great deal has been written about the complexities of engagement in learning, this is less true for students with severe intellectual disability. The concept of engagement of these students remains strictly behavioral. Engagement as a complex construct, consisting of behavioral, cognitive, and emotional components, must be addressed as…

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…

There is a dearth of research describing the small population of students who have significant cognitive disabilities and are also English learners (ELs). This study expands what is known about this population by describing EL students who participated in Dynamic Learning Maps Alternate Assessments in 16 states during the 2016-2017 year. Data…

Children's skill level in using a spoon facilitates increased independence during mealtimes and greater control over the pace and quantity of food intake, which has important implications for health and self-determination. Children with severe multiple disabilities, including cognitive and visual impairment (VI), require intensive instruction to…

An important part of quality of life for people with moderate and severe disabilities (MSDs) is being involved in extracurricular and community activities. However, volunteers, who may not have experience with including people with MSDs, lead most community activities. The purpose of this study was to demonstrate the effectiveness of teacher…

This study investigated educational experiences for students with significant cognitive disability (SCD) taught in self-contained high school classrooms. Nineteen students and nine teachers across five high schools and four school districts participated. A time-sampling method was used to describe the ecological, teacher, and student behaviors of…

Effective vocational instruction is an essential aspect of preparing students with intellectual and developmental disabilities (IDD) for the world of work. We systematically reviewed research on instructional methods used to teach employment skills to secondary students with IDD. We identified 56 studies involving 766 participants with IDD. Four…

Using a modified system of least prompts, two classroom teachers taught three participants with moderate intellectual disability to generate questions about United States history. After reading brief portions of the text aloud to the participants, the teachers taught participants to identify if the answer to the question was in the book or not in…
