Single-case research designs (SCRDs) are rigorous methods used to investigate the effects of interventions on socially important outcomes. A hallmark of SCRDs is repeated measurement of observable behavior presented in time-series graphs. The construction of time-series graphs can inflate Type I or Type II errors made via visual analysis. In the…

Single-case research designs are useful for learning disability researchers interested in refining novel interventions (e.g., new mathematics intervention) before scaling, small n populations (e.g., students with comorbid learning and emotional and behavioral disabilities), and testing unique conditions (e.g., remote locales). Much attention has…

Many students with learning disabilities (LD) do not master basic reading skills, which affects later reading fluency and reading comprehension development. Single-case experimental design (SCED) research yields unique opportunities to better understand which aspects of a basic reading intervention are effective with a particular student,…

Some students with visual impairments have not learned to read print or braille due to a variety of factors. The inability to read proficiently affects all areas of a person's life. Thus, it is essential that teachers of students with visual impairments (hereafter called "teachers") are systematic and use research-based practices in…

The current case study examined the effects of a specialized private Christian school for neurodiverse learning-disabled students. Research supports the creation of an educational environment that meets not only the academic needs of these diverse learners but also prioritizes creating a safe social-emotional place for learning. Further, the study…

Single-case designs substantiate the effectiveness of interventions for people with disabilities and other populations through the repeated measurement of behavior over time. Consequently, employing accurate and reliable systems of measurement is critical to the validity of single-case designs. Much of the data in single-case research are…

The purpose of this study was to examine the efficacy of a graphic organizer for improving the expository text comprehension of adolescent Spanish-English bilingual students with learning disabilities. Students were two females and one male. Using a multiple baseline single case design, researchers taught students to create a funnel map graphic…

This article, part of the "Learning Disability Quarterly" special series dedicated to single-case research design (SCRD), summarizes the review process and outlines how to provide high-quality SCRD study manuscript reviews. We offer recommendations for the entirety of the review process, including accepting the role of reviewer,…

There are difficulties regarding the identification of twice-exceptional students in Turkey. These children can be identified properly by way of multidimensional assessment. The purpose of the present study was to examine through family interviews, child interviews, products of the child and non-verbal intelligence tests the areas of difficulty…

The purpose of this single case design study was to examine the efficacy of a graphic organizer for improving the reading comprehension of middle school Spanish-English bilingual middle school students with learning disabilities. Students included two females and one male student. Using a multiple baseline across participants design, students were…

Background: Joe was referred to the Community Learning Disabilities Team (CLDT) for support around low mood and overeating. Initial formulation suggested compassion focused therapy (CFT) as an intervention. The evidence base for using CFT with people with learning disabilities is currently limited. Materials and Methods: Adaptations were made to…

Background: The main assumption of narrative therapy is that people are the "experts" on their own lives. When working with people with a learning disability, it can often be the case that the client's voice is not the primary voice. This is due to the fact that others "hold" the story for the client. When the story is,…

Despite increased attention to the academic progress of English learners (ELs) with disabilities as a result of the Every Student Succeeds Act of 2015, research has yet to investigate the educational opportunities of these students in secondary grades. This qualitative embedded case study examined the curricular access of 10 ELs with disabilities…

This study presents a single case study of how a remedial mathematics teacher incorporated an instructional intervention into her teaching practices in order to teach counting to a pupil with mathematical learning difficulties. This new theory-driven intervention was developed by the authors of this study. Dyscalculia is a term which refers to a…

There is controversy regarding the relative merits of cognitive assessment for the identification of learning disabilities. Proponents of cognitive assessment have suggested that multitiered systems of support (MTSS) should be supplemented with routine, systematic assessment of cognitive processes following a determination of inadequate response…
