A multiple-probe design was used to investigate planning and persuasive paragraph writing by three secondary students with disabilities and writing difficulties. The intervention consisted of one-on-one explicit instruction in persuasive writing and the use of a technology-based graphic organizer (TBGO) with embedded strategies and supports.…

Instruction targeting the underlying math problem structure is identified as an evidence-based practice for students with a specific learning disability (SLD). Furthermore, schema-based instruction is identified as a potentially evidence-based practice for students with a SLD. This study extended prior work by (a) using a teacher as the…

An established research base exists for using video modeling to teach students with severe disabilities. However, the application of this strategy for teaching academic skills to students with a learning disability is less known, particularly in secondary mathematics. Video modeling provides a resource for supplementary instruction using…

Identifying mathematical interventions that practitioners can implement to improve the mathematical problem solving (PS) of students is a need for the field. Literature on the PS performance of students with disabilities has grown; recently, schema instruction (SI) has been suggested as an evidence-based practice. The purpose of this study was to…

Students who report high levels of intrinsic motivation (IM) perform better on academic tasks compared with students who report low levels of IM. However, there is a paucity of data on IM for several disability categories (e.g., intellectual disability). The focus of this study was to use a nationally representative sample of students with…

While mathematics education is key to the post-school outcomes of students with disabilities, it has received less attention in research and practice compared with other aspects of educating this population. Skill maintenance is particularly crucial in mathematics because students build upon prior knowledge across grade levels. They also need to…

Special education certification is used as an indicator of teaching quality in research, practice, and policy. This study examined whether elementary and middle school students with learning disabilities (LD) or emotional/behavioral disorders (EBD) scored better on state math and English language arts (ELA) assessments in years when they were…

The present study examined the role of language capacities in explaining differences in social information processing (SIP) among three school-age groups: high-functioning children with autism spectrum disorder (ASD, IQ > 75), children with specific learning disorder (SLD), and children with typical development (TD). Participants were 96 boys…

Students with mathematics learning disabilities have a weak understanding of mathematical concepts that underlie success in Algebra I, such as ratios and proportional reasoning. In this study, researchers used a multiple baseline across participants design to evaluate the effects of a intervention based on a instructional trajectory of how…

This synthesis examined the effects of spelling interventions on spelling outcomes for students with disabilities in Grades 6 through 12. Thirteen single-case design studies were identified for inclusion in the review. No studies used a treatment/comparison design. The most common types of interventions involved systematic study strategies, such…

Six middle school students identified as having a specific learning disability or at risk for mathematical difficulties were taught how to solve multi-step equations by using the self-regulated strategy development (SRSD) model of instruction. A multiple-probe-across-pairs design was used to evaluate instructional effects. Instruction was provided…

Promoting the self-determination of adolescents with disabilities has become best practice in secondary education and transition services, but to date there have been no studies establishing a causal relationship between efforts to promote self-determination and enhancement of the self-determination of youth with disabilities. This article reports…

Students with significant cognitive disabilities are eligible to participate in two statewide testing options for accountability: alternate assessments or general assessments with appropriate accommodations. Participation guidelines are generally quite vague, leading to students "switching" test participation between years. In this…

This study explored how a teaching experiment, which taught double counting with a constructive task assignment according to an ongoing assessment, helped students with mathematics difficulties develop their multiplicative reasoning skills. The participants were two fifth graders with math learning disabilities and one at risk. A micro-genetic…

The least restrictive environment (LRE) mandate provides a preference for educating students with disabilities in general education classrooms while allowing separate class services as necessary to meet student needs. This study investigated changes in national LRE placement trends for students with disabilities from 1990-1991 through 2007-2008.…
