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,…

The purpose of this special series is to augment effective instruction for students with learning disabilities who are also considered culturally, racially/ethnically, linguistically, or otherwise diverse. In this paper, we acknowledge the central focus on technical rigor for the purpose of strengthening causal linkages between instruction and…

Since the learning disability (LD) population comprises the largest group receiving special education services, there is a need for research to examine the self-concept of this population at a global level. This systematic literature review synthesized 20 years of quantitative research (k = 16) about the self-concept of students with LD. The…

Single-case research design is a useful methodology for evaluating the presence of a functional relation between an intervention and the mathematical performance of students with a learning disability. However, a functional relation cannot be established with threats to internal validity of the design. External validity is impacted if researchers…

Four studies into characteristics and instructional needs of students with learning disabilities are summarized in this article. These studies are also reviewed in the wider context of mathematics intervention research in special education. These studies generally rely on qualitative methodology, and they are best understood in light of a…

This article synthesizes observation studies investigating reading instruction for students with learning disabilities (LD) in Grades K-12. A systematic search of the literature between 1980 and 2014 resulted in the identification of 25 studies. In addition to replicating and extending E. A. Swanson's synthesis, the research questions of studies…

The critical issue Connor, Gallagher, Ferri, Dudley-Marling, and others have put before everyone in this special issue of the "Learning Disability Quarterly" is the hegemony of quantitative methodologies and subsequent marginalization of qualitative research. On this the author is in full agreement. When the human sciences use only quantitative…

Because high stakes are now attached to standardized assessments of student progress, policy makers, administrators, practitioners, and parents must understand how to most effectively and accurately measure the performance of all students, including students with learning disabilities (LD). To accomplish this, test accommodations are provided on…

The Council for Learning Disabilities' Research Committee hosted a "Must Read" session at the 35th Annual International Conference in which they discussed influential articles published between August 1, 2012, and July 31, 2013. Articles were selected in six areas relevant to learning disabilities research and practice: response to…

The field of learning disabilities (LD) has a complex and complicated history. Tensions over definitions, eligibility criteria, service delivery models, and best practices, as well as epistemological debates, have been a part of that history from its inception. Given our collective struggles, as well as the current realities facing the field,…

This article provides an introduction to theoretical ideas and practices from the so-called "philosophers of difference"--Foucault, Derrida, and Deleuze and Guattari--as an invitation to think differently about the construction of learning disability and to envision new forms of learning. Two key concepts, Foucault's transgression and…

This special series represents collective courage because what is willing to be risked may be profound. At center is a willingness to reach out and cultivate new conversations on disability. Indeed, the artists who contribute to Ware's article are key co-authors; their art ushers us into a new disability literacy that extends and challenges…

In the mid-1970s, Donald Hammill and his colleagues authored three scathing critiques of the two most trusted scientific traditions of learning disability treatment--movement education and psycholinguistic training (Hammill, 1972; Hammill & Larsen, 1974; Hammill, Goodman, & Wiederholt, 1974). These critical reviews of research rejected the older…

The dominant approach to research in learning disabilities utilizes experimental and quasi-experimental designs to identify the most effective instructional strategies for students with learning disabilities. Research is always undertaken from a point of view, yet the discourse on "what works?" is generally silent on how theoretical frameworks…

In an effort to establish more universal research standards the Council for Learning Disabilities (CLD) Research Committee proposes a set of guidelines to be used for subject descriptions in LD research reports. (Author/CL)
