Publication bias is the disproportionate representation of studies with large effects and statistically significant findings in the published research literature. If publication bias occurs in single-case research design studies on applied behavior-analytic (ABA) interventions, it can result in inflated estimates of ABA intervention effects. We…

Autistic adults are significantly more likely to experience co-occurring mental health conditions such as depression and anxiety. Although intervention studies are beginning to be implemented with autistic adults to address mental health outcomes, little is known about what research autistic adults feel is needed, or what mental health outcomes…

Rigorous evidence of program effectiveness has become increasingly important with the 2015 passage of the Every Student Succeeds Act (ESSA). One question that has not yet been fully explored is whether program evaluations carried out or commissioned by developers produce larger effect sizes than evaluations conducted by independent third parties.…

This article is an exploratory study of graduate-level instruction on research designs and methods for pre-service school librarians (PSSLs). Using a focus group of one cohort of PSSLs, we examine students' perceptions of understanding research methods, course content and delivery, and self-reported application of new knowledge from a sequence of…

Clustered observational studies (COSs) are a critical analytic tool for educational effectiveness research. We present a design framework for the development and critique of COSs. The framework is built on the counterfactual model for causal inference and promotes the concept of designing COSs that emulate the targeted randomized trial that would…

The Association of American Universities (AAU) "Report on the AAU Campus Climate Survey on Sexual Assault and Misconduct" surveyed over 180,000 undergraduate and graduate students and found significant rates of sexual violence on college campuses across the United States with even greater rates experienced by students who identify as…

The present study reviewed papers published in the Web of Science database from 2014 to 2020 in SSCI indexed journals on learner- and instructor-related challenges for learners' engagement in MOOCs based on the Technology-Based Learning Model. The focus is on research design, instructor-related factors that foster and frustrate learner engagement,…

With the ubiquitous presence of media devices, media multitasking has become prevalent in an educational context. Several authors have synthesized the literature on this topic, but no systematic review has been carried out so far. The present study fills this gap by examining the academic papers in the past decade to delineate the research trends,…

The article describes the inclusive perspective of instruction of multi-stage practical projects in undergraduate non-STEM statistics and data mining courses at an academic college in Israel. The student population is highly diverse, comprising individuals from various cultural and ethnic groups. The study examines the impact of diversity on…

Clinical trials have different designs: In late stage drug development, the parallel trial design is the most frequent one; however, the crossover design is not rare; different techniques are used to analyse their results. Although both designs measure the same treatment effect, combining parallel and crossover trials in a meta-analysis is not…

Although visual analysis has been the primary method of analysis in single-case designs (SCD), numerous statistical analyses have been developed to quantify SCD intervention effects and enable SCDs to be included in evidence-based practice reviews. This study investigated the correspondence between expert visual analysis and three effect sizes for…

Education experiments frequently assign students to treatment or control conditions within schools. Longitudinal components added in these studies (e.g., students followed over time) allow researchers to assess treatment effects in average rates of change (e.g., linear or quadratic). We provide methods for a priori power analysis in three-level…

The problem of assessing whether experimental results can be replicated is becoming increasingly important in many areas of science. It is often assumed that assessing replication is straightforward: All one needs to do is repeat the study and see whether the results of the original and replication studies agree. This article shows that the…

A systematic review explored the evidence base of literacy intervention studies that examined the early years of schooling (preschool through first grade) of participants who were d/Deaf or hard of hearing (d/Dhh). Specific inclusion criteria were used to select single-case design (SCD) studies published in peer-reviewed journals between 2004 and…
