Survey-based research is vital in education and social sciences, offering insights into human behaviors and perceptions. The prevalence of such studies in medical education has risen by 33% over the past decade. Despite this growth, the utility of survey findings depends on the study design quality and measure validity. Many manuscripts are…

Divided into two volumes, "Handbook of Special Education Research" provides a comprehensive overview of critical issues in special education research. This first volume addresses key topics in theory, methods, and development, exploring how these three domains interconnect to build effective special education research. Each chapter…

This guide is addressed to policy officials, program providers, and researchers who are seeking to: (1) identify and implement social programs backed by valid evidence of effectiveness; or (2) sponsor or conduct an evaluation to determine whether a program is effective. The guide provides a brief overview of which studies can produce valid…

This issue of "FOCUS" discusses external validity and what rehabilitation researchers can do to help practitioners answer the question "How far can we generalize this finding-- is it applicable to other clients/patients, with different characteristics, in dissimilar settings treated by other clinicians?," which clinicians and…

This manual provides guidance and documentation for users of the longitudinal kindergarten-fourth grade (K-4) data file of the Early Childhood Longitudinal Study, Kindergarten Class of 2010-11 (ECLS-K:2011). It mainly provides information specific to the fourth-grade round of data collection. The first chapter provides an overview of the…

This guide is designed to help researchers make sure that their research reports include enough information about study measures so that readers can assess the quality of the study's methods and results. The guide also provides examples of write-ups about measures and suggests resources for learning more about these topics. The guide assumes…

This manual provides guidance and documentation for users of the longitudinal kindergarten-fourth grade (K-4) public-use data file of the Early Childhood Longitudinal Study, Kindergarten Class of 2010-11 (ECLS-K:2011), which includes the first release of the public version of the third-grade data. This manual mainly provides information specific…

The authors center their presentation of material around a conceptual understanding of psychometric issues, such as validity and reliability, and on purpose rather than procedure, the "why" rather than the "how to." Their goal is to introduce psychometric principles at a level that is deeper and more focused than found in introductory…

Since research conclusions derived from inappropriate statistical methodologies can lack accuracy, the article describes a technique appropriate to the heterogeneity of special needs groups in which subjects are assigned to fairly homogeneous subgroups. The technique is related to research in reading with this population. (DB)

Compares and contrasts standards and techniques of qualitative and quantitative usability testing methodologies. Focuses on ways technical communicators can ensure rigorous tests in terms of the validity and reliability of findings, defining criteria of validity and reliability for both quantitative and qualitative methods. Presents a list of…

The main features of a multiple site, structured case study design are presented. The nature of explanatory patterns, how case study investigators pursue and recognize valid patterns, and how an analyst can apply the same logic to cross-site analysis are discussed. (Author/BW)

External and implementation factors and their potential threats to field test validity and the practical realities of the field testing process on results are discussed. External factors include site selection, negotiations, contracts, site monitoring, training, and type of product. Implementation factors include motivation, dependence on local…

The development of a valid and reliable method of assessing recreational patterns was the purpose of this study. Recreational activities were classified using activity clusters and the setting for the activity. This information yielded a two-dimensional matrix for viewing activities. The first dimension of the matrix was the recreational activity…

Evaluation studies on educational questions attempt to provide answers in the form of conclusions or inferences which are derived from the information collected. Valid inferences are a result of careful research design for the study, and may be causal, descriptive, value-oriented, or probabilistic. Basic steps in designing an evaluation study are…

Discusses how meta-analysis allows clinicians to determine objectively both presence and size of an effect or correlation within the existing literature by pooling the results of various studies and performing statistical analyses. Describes the risks and benefits of applying information obtained from meta-analysis into clinical practice.…
