Research of issues related to disability is consistently evolving in several social science related fields such as social work, psychology, sociology, and education. Disability research often employs large public datasets for researchers to conduct secondary analysis. However, these datasets come with many limitations that can impact the overall…

A randomized experiment that measures the impact of a social policy in a sample of the population reveals whether the policy will work on average with universal application. An experiment that includes only the subset of the population that volunteers for the intervention generates narrower "proof-of-concept" evidence of whether the…

The Biggest Mover Program, an educational program to improve daily exercise and healthy eating was developed to address the learning needs of students with intellectual and developmental disabilities and physical challenges. The program was part of a three-part program to improve the knowledge of students, staff, and teachers through the use of…

Simulation studies use computer-generated data to examine questions of interest that have traditionally been used to study properties of statistics and estimating algorithms. With the recent advent of powerful processing capabilities in affordable computers along with readily usable software, it is now feasible to use a simulation study to aid in…

The Every Student Succeeds Act (ESSA) of 2015 (Public Law 114-95) requires each state to create a plan for its statewide accountability system. In particular, ESSA calls for state plans that include strategies for reporting education outcomes by grade for all students and for economically disadvantaged students, students from major racial and…

Historically, researchers focused on individuals with severe disabilities have utilized single-subject research methodologies to study the application of the behavioral theory to learning. In contrast, disability studies scholars have primarily used qualitative research methodologies to study quality of life or policy issues related to individuals…

Latent transition analysis (LTA) was initially developed to provide a means of measuring change in dynamic latent variables. In this article, we illustrate the use of a cognitive diagnostic model, the DINA model, as the measurement model in a LTA, thereby demonstrating a means of analyzing change in cognitive skills over time. An example is…

The Missouri Department of Elementary and Secondary Education (DESE), in response to recommendations in the Annual Report of the Advisory Council on the Education of Gifted and Talented Students (2015), has produced this document to provide guidance for school districts to more equitably identify and meet the needs of traditionally…

This article is grounded in social constructivist perspectives of learning: its purpose is to provide an overview of the "Interactions Sociales et Acquisition" (ISA) [Social Interactions and Acquisition] French group's research that examines how a peer-assisted learning (PAL) group context facilitates students' acquisition of motor and…

Although statistics such as kappa and phi are commonly used to assess agreement between tests, in situations where the base rate of a disorder in a population is low or high, these statistics tend to underestimate actual agreement. This can occur even if the tests are good and the classification of subjects is adequate. Relative improvement over…

This report was developed in partnership with Ready At Five. It lays out the critical importance of children starting school fully prepared to succeed in kindergarten. Most importantly, the report shares what everyone has learned from the 2010-2011 Maryland Model for School Readiness (MMSR) data about the school readiness of Maryland's children:…

Quantitative behaviour analysis requires the classification of behaviour to produce the basic data. This can be challenging when the theoretical taxonomy does not match observational limitations, or if a theoretical taxonomy is unavailable. Binary keys allow qualitative observation to be used to modify a theoretical taxonomy to produce a practical…

Though clinical judgement is necessary for appropriate diagnosis and provision of services to learning disabled children, such judgement must be based on objective evidence. A statistical procedure for applying the severe discrepancy criterion dictated in federal regulations is suggested for objectifying learning disability diagnosis. (Author/DB)

This article describes the development, content, and use of four questionnaires that comprise the Assessment of Campus Climate to Enhance Student Success with the focus on the Faculty Questionnaire. Faculty development activities are described as an example of how the questionnaires can be used to enhance knowledge and change attitudes and…

This paper summarizes results of a legislatively mandated study of the incidence of students with "severe and/or high cost" disabilities across California within the context of the new census-based funding approach (which distributes funds based on the overall census of school-aged children rather than a count of children receiving…
