Manipulative-based instructional sequences--including both concrete and virtual manipulative instructional sequences--are evidence-based or research-based mathematical interventions for students with disabilities. However, as options for manipulative-based instructional sequences increase, educators need support in deciding the best approach. In…

A large number of students with and without disabilities--including students at-risk--are currently learning online through synchronous and/or asynchronous instruction. As such, it is important for educators to be equipped with evidence-based practices--or at the minimum research-based practices--that can be adapted or modified to teach students…

Mathematical fluency supports maintenance of mathematical skills (Shurr et al., 2019). Multiple interventions support fluency, including the use of games. However, limited research exists exploring games as a means of increasing student fluency in mathematics. In this single case design study, researchers examined the relation between four…

Transition is important to all students but especially important to students with intellectual disability who may need additional supports throughout their vertical transitions in education. This chapter discusses different vertical transitions students with intellectual disability face in education, with particular attention to the movement from…

Manipulatives offer students with disabilities access and support in classrooms. However, it is important for educators to be aware that concrete manipulatives are not the only option. Teachers serving students identified with a disability in the middle grades may consider selecting virtual manipulatives as supplement, complement, or in lieu of…

Mathematics is an important but also under-explored area of education for students with disabilities, including middle school students with intellectual and other developmental disabilities. In this study, researchers taught middle school students with intellectual and developmental disabilities (IDD) to solve word problems grounded in life skills…

Assistive technology supports students with disabilities in a variety of ways, including serving as a means of instruction. Although virtual manipulatives can serve as an assistive technology tool, limited research examines virtual manipulatives in-and-of-themselves to support students with disabilities. This study explored app-based virtual…

Research regarding the role of reading fluency for middle school-aged students with disabilities is limited, particularly for students with attention deficit hyperactivity disorder (ADHD). This study compares the roles--repeated silent reading (RSR), oral reading (OR), and repeated oral reading (ROR)--on grade-level comprehension for students…

Basic mathematic skills at the early age are foundational for later learning. Many students with autism spectrum disorder (ASD) struggle in academic learning without sufficient support. Research in the area of concrete manipulatives--tangible representations of abstract concepts--has been found effective. In addition, promising research has…

Fractions are foundational concepts for more advanced mathematics as well as used throughout daily living, for all students, including students with disabilities. This study explored the virtual-abstract (VA) instructional sequence with regard to the acquisition and maintenance of fraction behaviors for three middle school students with mild…

While research exists on parent expectations associated with post-school outcomes of youth with intellectual disability, limited research examines issues of parent--and youth--post-school expectations relative to issues of community, such as living in rural versus urban or suburban settings. Through a secondary analysis of the National…

Virtual manipulatives are an emerging intervention to support students with disabilities in mathematics. Through a multiple probe across participants design, researchers examined use of an intervention package consisting of a virtual manipulative (i.e., the Two-Color Counter app-based manipulative) and the system of least prompts (SLP) to support…

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…

Transition planning is an important element of special education. This study is a secondary data analysis of the National Longitudinal Transition Study 2012 (NLTS 2012) that examined parent, student, and adult service agency involvement in the transition process for secondary students with intellectual disability (ID). The NLTS 2012 is the third…

Although often considered a more advanced area of mathematics, principles of algebra are taught throughout different mathematical concepts, and algebra is often considered gateway mathematical knowledge for more advanced mathematical concepts. For this reason, attention is needed toward making algebraic instruction more accessible to all types of…
