This article reports the results of a follow-up analysis of 779 students with disabilities who participated in group-randomized, control group studies designed to examine the efficacy of self-determination interventions in secondary school to examine the relationship between self-determination status when exiting high school and adult outcomes 1…

Teaching students to develop and use a Summary of Performance (SOP) may be one method for teaching self-advocacy skills to ensure students with intellectual disability can advocate for accommodations and supports during Person-Centered Planning (PCP) meetings and in postschool employment settings. This study used a multiple-probe across…

Researchers and practitioners have struggled to promote optimal academic, behavioral, and postschool outcomes for historically marginalized youth from culturally and linguistically diverse backgrounds. While there is a growing body of evidence-based interventions in special education, the extent to which these interventions are culturally…

This replication study focused on the effectiveness of two different intervention approaches, activity-based intervention and embedded direct instruction, on the acquisition, generalization, and maintenance of phonological awareness, a key area of emergent literacy, by preschool children with language delays. Five male preschool participants with…

Twelve seventh- and eighth-grade students with emotional disturbance participated in a multiple probe, multiple baseline design two-phase intervention study to improve persuasive writing skills. The first phase after baseline taught students to plan and write persuasive essays including counterarguments. In the second phase, students were taught…

The identification of evidence-based practices continues to provoke issues of disagreement across multiple fields. One area of contention is the role of single-subject design (SSD) research in providing scientific evidence. The debate about SSD's utility centers on three issues: sample size, effect size, and serial dependence. One potential…

Students with emotional and behavioral disorders (E/BD) have academic deficits that affect their success in school. However, there are few research studies investigating what strategies work best for this population, especially in the area of writing. One promising intervention to support the writing skills of students with and at risk for E/BD is…

A single-participant multiple probe design across participants was used to evaluate the effectiveness of verbal rehearsal and graduated guidance to teach youth who were blind how to cross the street. This study replicated intervention procedures across settings along with the staggered entry of participants. Individuals learned to cross one or two…

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…

The purpose of this study was to conduct a preference trial as a preliminary test of preference effects on teacher behavior relative to implementation (adoption, adherence, quality). Teachers were randomly assigned to "preference" or "no-preference" groups and then trained to implement the intervention. Direct observation…

This investigation examined the effects of video modeling on the fine and gross motor task performance by three students with a diagnosis of moderate intellectual disability (Group 1) and by three students with a diagnosis of autism spectrum disorder (Group 2). Using a multiple probe design across three sets of tasks, the study examined the…

Evidence-based practices (EBPs) are instructional techniques that meet prescribed criteria related to the research design, quality, quantity, and effect size of supporting research, which have the potential to help bridge the research-to-practice gap and improve student outcomes. In this article, the authors (a) discuss the importance of clear…

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…

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…

English language learners (ELLs) struggle with solving word problems for a number of reasons beyond math procedures or calculation challenges. As a result, ELLs may not only need math support but also reading and linguistic support. The purpose of this study was to assess the effectiveness of a math comprehension strategy called Dynamic Strategic…
