Contrary to its typical presentation in scientific publications as a certain and linear process, in reality, the experimental method, not least the design aspect of it, requires a great deal of trial-and-error and ad hoc decision-making on the part of the researchers. This uncertain and contingent aspect of research, although little known outside…

Factorial surveys use a population of vignettes to elicit respondents' attitudes or beliefs about different hypothetical scenarios. However, the vignette population is frequently too large to be assessed by each respondent. Experimental designs such as randomized block confounded factorial (RBCF) designs, D-optimal designs, or random sampling…

Technological advances have led to an abundance of widely available data on every aspect of life today. Psychologists today have more information than ever before on human cognition, emotion, attitudes, and behavior. "Big Data in Psychological Research" addresses the opportunities and challenges that this data presents to psychological…

Single-case design has a long history of use for assessing intervention effectiveness for children with disabilities. Although these designs have been widely employed for more than 50 years, recent years have been especially dynamic in terms of growth in the use of single-case design and application of standards designed to improve the validity…

Technology-mediated learning has become a valuable tool, especially in the English language classroom. Nowadays, mobile learning is considered a significant educational tool for promoting education among learners. Several recent studies have attempted to examine different aspects of mobile learning. The size of the experimental group, and the…

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,…

This content analysis focuses on content from four major gifted journals (i.e., "Gifted Child Quarterly, Journal for the Education of the Gifted, Journal of Advanced Academics, and Roeper Review"). After applying a priori search and inclusion protocols, a final sample (N = 202) of articles examining Black and Brown students in gifted…

Introduction: Clinician-client relationships impact treatment outcomes in speech-language pathology. Training clinicians to improve these relationships might therefore improve treatment outcomes but has not been examined in the field. This study is a preliminary investigation of whether training student clinicians can enhance clinician-client…

Students often believe that statistical significance is the only determinant of whether a quantitative result is "important." In this paper, I review traditional null hypothesis statistical testing to identify what questions inferential statistics can and cannot answer, including statistical significance, effect size and direction,…

Video-based intervention (VBI) is an evidence-based practice for teaching a wide array of skills to autistic children and young adults; however, a limited number of studies have examined the effectiveness of parent-implemented VBI when teaching children functional skills in a home setting. The purpose of this evidence-based systematic review was…

The general assembly meeting of the United Nations Educational, Scientific and Cultural Organization (UNESCO) in 2015 adopted the 17 Sustainable Development Goals (SDGs) aimed at achieving a better and more sustainable world by 2030. Incorporating sustainable values through a series of pedagogical strategies into university curricula to help…

How researchers use statistical analyses shapes their research toward or away from an anti-racist agenda. In this article, we demonstrate how developmental scientists can use the QuantCrit framework to critically examine the process of conducting quantitative analyses. In particular, we focus on mixture modeling to clearly demonstrate how the…

Computational thinking (CT) is being recognized as a critical component of student success in the digital era. Many contend that integrating CT into core curricula is the surest method for providing all students with access to CT. However, the CT community lacks an agreed-upon conceptualization of CT that would facilitate this integration, and…

Education is seen as an important vehicle to foster relationships with countries in the Asia-Pacific region -- particularly with Australia's most important economic partner, China. There are many prior studies that have explored the impact of Learning Management Systems (LMSs) on users, through a variety of research designs. However, the diversity…

Planned missing data designs allow researchers to have highly-powered studies by testing only a fraction of the traditional sample size. In two-method measurement planned missingness designs, researchers assess only part of the sample on a high-quality expensive measure, while the entire sample is given a more inexpensive, but biased measure. The…
