Background: Intercoder reliability is a statistic commonly reported by researchers to demonstrate the rigour of coding procedures during data analysis. Its importance is debatable in the analysis of qualitative interview data. It raises a question on whether researchers should identify the same codes and themes in a transcript or they should…

Manipulation checks are an essential component of quality experimental design in motor learning. Guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses framework, this methodological systematic review examined the utilization of manipulation checks in focus of attention research. Seventy-eight protocols from four…

Objective: To analyze the literature in which researchers have utilized the National College Health Assessment (NCHA) I or the NCHA II. Participants and Methods: The authors selected peer-reviewed articles published between 2004 and July 2013 utilizing a single search term: National College Health Assessment. Articles were assessed for instrument…

Staff members at Sesame Workshop asked us to conduct a meta-analysis of their proprietary evaluation research on the effects of viewing international versions of "Sesame Street." Given global crises in early childhood education, and given the wide reach of "Sesame Street," it was of considerable interest to us whether there…

Although vocabulary instruction is a pressing need for postsecondary reading instructors, a minimal amount of current postsecondary scholarship addresses this need, and almost no current scholarship addresses the textbook tradition of morphemic analysis (MA). The present article reviews the literature on MA instruction and argues for teaching MA…

Social narratives (e.g., Social Stories™) are common antecedent-based interventions promoted for the purposes of improving prosocial behaviors and reducing challenging behavior for children with and without disabilities. Although they are commonly prescribed and used, their effectiveness has almost exclusively been assessed for children with…

When classifying the evidence base of practices, special education scholars typically appraise study quality to identify and exclude from consideration in their reviews unacceptable-quality studies that are likely biased and might bias review findings if included. However, study quality appraisals used in the process of identifying evidence-based…

Systematic reviews of literature are studies that strategically search for published research on a specific topic in order to synthesize what is known about the topic. This systematic review describes 157 articles on synchronous online learning (SOL) from thirty-four different countries on instructional setting, content areas, participant…

The authors outline the application of latent class analysis (LCA) to classroom observational instruments. LCA offers diagnostic information about teachers' instructional strengths and weaknesses, along with estimates of measurement error for individual teachers, while remaining relatively straightforward to implement and interpret. It is…

The purpose of this study was to examine the quality of quantitative articles published in the "Journal of Counseling & Development." Quality concerns arose in regard to omissions of psychometric information of instruments, effect sizes, and statistical power. Type VI and II errors were found. Strengths included stated research…

Recently, there has been an increasing level of interest in subscores for their potential diagnostic value. Haberman (2008) suggested a method based on classical test theory to determine whether subscores have added value over total scores. This paper provides a literature review and reports when subscores were found to have added value for…

The article suggests that though narrative inquiry as a research methodology entails free conversations and personal stories, yet it should not be totally free and fictional as it has to conform to some recognized standards used for conducting educational research. Hence, a qualitative study conducted by Russ (1999) was explored as an exemplar…

The purpose of this paper is to discuss ways in which developmental psychology suffers from the lack of an appropriate technology of measurement and statistical analysis. The paper begins by noting that developmental psychology is the study of change; that individuals develop through a succession of "stages" which are separated by…

Examines consistency of results and variables that may confound validity in child sexual abuse cases. Concludes that the ways in which information on the incidence and prevalence of child sexual abuse has been collected, analyzed, and reported have been flawed to the extent that few reliable conclusions can be made. Includes suggestions for…

Issues of reliability and validity in ethnographic design are compared to their counterparts in experimental design. Threats to the credibility of ethnographic research are summarized and categorized. Strategies intended to enhance credibility (study design, data collection, data analysis, and presentation of findings) are incorporated throughout…
