The aim of this paper is to introduce a software that is appropriate for the generalizability theory for not only balanced but also unbalanced data sets. Because it is possible to have unbalanced data sets while conducting a study, the researchers have devised an easy solution, other than deleting data, to balance the design to cope with this…

The purpose of this book is to collect, organize and disseminate collective wisdom with respect to designing, conducting, and publishing quality research in mathematics education. This wisdom will be gleaned from among those who, over the past several decades, have been instrumental in guiding the field in the pursuit of excellence in mathematics…

Objectives: To determine ADHD research priorities from the perspective of ADHD professionals internationally. Method: A two-stage modified Delphi design was used. In Stage 1 (qualitative), participants listed research questions relating to ADHD that they perceived to be most important (N = 132). In Stage 2 (quantitative), participants were then…

Transnational education (TNE) occurs when higher education institutions traverse borders to provide educational experiences outside their home countries. Such mobility creates several research challenges, as such institutions exist between worlds. They must balance home and host country legal requirements, navigate home and branch administrative…

Prior studies indicate that faculty often struggle with Scholarship of Teaching and Learning (SoTL) research due to limited knowledge of relevant research methodologies and data analysis techniques (Boshier, 2009; Kim et al., 2021; McKinney, 2006). Faculty developers at a teaching-intensive institution created an innovative, scaffolded model to…

This study aims to obtain data and information about the effectiveness and practicality of YouTube in learning German speaking for second-semester students of the German language education study program in terms of learning outcomes and student responses. This study was experimental research, and the experimental model used was a pre-experimental…

This case study is based on a program evaluation of a professional certificate program that trains early childhood care and education providers to build and support young children's emotional literacy. The research project described in the case study will address approaches to methodological combination, justifying research design and changes to…

Systems-level consultation and implementation science research has resulted in increased understanding of how to facilitate large-scale use of evidence-based practices. This article aims to build upon what has been learned to-date by calling for consultation researchers to focus more on the human interactions within change processes. The rationale…

In this commentary, we complement other constructive critiques of educational randomized control trials (RCTs) by calling attention to the commonly ignored role of context in causal mechanisms undergirding educational phenomena. We argue that evidence for the central role of context in causal mechanisms challenges the assumption that RCT findings…

Centres of Excellence (CoE) have become a common research policy instrument in several OECD countries the last two decades. The CoE schemes are in general modelled on the organisational and research practices in the natural and life sciences. Compared to 'Big science', the humanities have been characterised by more individual research, flat…

The testing effect is 1 of several memory effects moderated by experimental design, such that the effect on free recall is larger in a mixed-list than pure-list design (Mulligan, Susser, & Smith, 2016). The current experiments assess hypotheses regarding why this pattern is found. Three extant accounts of design effects (Nguyen & McDaniel,…

Single-case design (SCD) is a research methodology that may be utilized to establish the presence of a functional relation between an independent and dependent variable. Recent research has found the design to frequently be used within school psychology in the evaluation of intervention procedures. However, the overall prevalence of the design…

School counselors are tasked with many activities, including demonstrating the effectiveness of interventions they use with students. The American School Counselor Association recommends that school counselors include assessment, appraisal, and evaluation of delivery and program management in their school counseling program. Single-case research…

This supplement concerns Appendix E of the "What Works Clearinghouse (WWC) Procedures Handbook, Version 4.1." The supplement extends the range of designs and analyses that can generate effect size and standard error estimates for the WWC. This supplement presents several new standard error formulas for cluster-level assignment studies,…
