Statistics and methodology play a crucial role in psychological research, and university psychology courses teach students the theory and application of various statistical methods. However, students who conduct their own research projects oftentimes face problems which are specific to their data and cannot be solved using standard curricular…

Cultural dimensions of autism spectrum disorder (ASD) are relatively unexplored in the research literature. The current study is a systematic scoping review describing social, educational, and psychological research focused on individuals with ASD and their family members in Arab countries and cultures. Seventy studies met eligibility criteria.…

Null hypothesis significance testing (NHST) provides an important statistical toolbox, but there are a number of ways in which it is often abused and misinterpreted, with bad consequences for the reliability and progress of science. Parts of contemporary NHST debate, especially in the psychological sciences, is reviewed, and a suggestion is made…

In this discussion paper, teaching and learning are characterized as being situated, complex, and reciprocally interactive activities. Accordingly, a teacher's pedagogical actions are always action and reaction at the same time. Irrespective of the reciprocally interactive nature of teaching and learning, educational research has sought to…

Evidence-based practices (EBP) in psychology and education are necessary for the development of best practices and required by law. However, EBP is a term that is often freely applied in these settings without considering the implications of the meaning of "evidence-based." Evidence-based practices are defined as the process of…

In this study, we re-analyze recent empirical research on replication from a meta-analytic perspective. We argue that there are different ways to define "replication failure," and that analyses can focus on exploring variation among replication studies or assess whether their results contradict the findings of the original study. We…

Across continental Europe, educational research samples are often divided by 'migrant background', a binary variable criticized for masking participant heterogeneity and reinforcing exclusionary norms of belonging. This study endorses more meaningful, representative, and precise research by offering four guiding questions for selecting relevant,…

For surveys of complex issues that entail multiple steps, multiple reference points, and nongradient attributes (e.g., social inequality), this study proposes a new multiprocess model that integrates ideal-point and dominance approaches into a treelike structure (IDtree). In the IDtree, an ideal-point approach describes an individual's attitude…

"Creating Communities of Care: How Charter Schools can Develop Systems that Support Student Mental Health" provides new tools to help charter schools adapt to the changing needs of their students and staff. This resource focuses on improving student mental health and well-being to help set the foundation for school community wellness.…

William Dean Crano is the Stuart Oskamp Distinguished Professor of Psychology in the School of Behavioral and Organizational Sciences at Claremont Graduate University. A social psychologist, Crano received his MS and PhD degrees from Northwestern University, where Donald T. Campbell was his advisor and mentor. Dr. Crano has served on the faculties…

Single-case experimental methods are used across a range of educational and psychological research. Single-case data are analyzed with a variety of methods, but no statistic has demonstrated clear superiority over other methods. The time-series nature of single-case designs requires special consideration for baseline trend and autocorrelation when…

The purpose of this work is to provide an overview of complex systems research for educational psychologists. We outline a philosophically and theoretically sourced definition of complex systems research organized around complex, dynamic, and emergent ontological characteristics that is useful and appropriate for educational psychology. A complex…

Having surveyed the history and methods of meta-regression in a previous paper, in this paper, we review which and how meta-regression methods are applied in recent research syntheses. To do so, we reviewed studies published in 2016 across four leading research synthesis journals: "Psychological Bulletin," the "Journal of Applied…

With the reauthorization of the Individuals with Disabilities Education (Improvement) Act (IDEA) in 2004, local education agencies (LEAs) were no longer required to employ an IQ-achievement discrepancy model in the identification of a specific learning disability (SLD). Rather, districts were permitted to use data from a Response to Intervention…

Computer vision algorithms have made tremendous advances in recent years. We now have algorithms that can detect and recognize objects, faces, and even facial actions in still images and video sequences. This is wonderful news for researchers that need to code facial articulations in large data sets of images and videos, because this task is time…
