Short comparative interrupted times series (CITS) designs are increasingly being used in education research to assess the effectiveness of school-level interventions. These designs can be implemented relatively inexpensively, often drawing on publicly available data on aggregate school performance. However, the validity of this approach hinges on…

This article calls for a common research model that can be replicated across institutions to systematically collect data on the impact of education abroad participation on college graduation rates. The ultimate goal of the proposed GRAD LEAP (Leveraging Education Abroad Participation for Graduation) model is to facilitate a meta-analysis yielding…

In his proposal for comparative education, Marc Antoinne Jullien de Paris argues that the comparative method offers a viable alternative to the experimental method. In an experiment, the scientist can manipulate the variables in such a way that he or she can see any possible combination of variables at will. In comparative education, or in…

Qualitative comparative analysis (QCA) was originally developed as a tool for cross-national comparisons in macrosociology, but its use in evaluation and evidence synthesis of complex interventions is rapidly developing. QCA is theory-driven and relies on Boolean logic to identify pathways to an outcome (e.g., is the intervention effective or…

Discipline-based education research (DBER) conducted by faculty within geoscience departments can address identified needs in undergraduate geoscience education. This study explores the evolution of undergraduate geoscience education research (GER) from 1985 to 2016, primarily in terms of the types of published research and secondarily in terms of…

This dissertation consists of three manuscripts. The manuscripts contribute to a budding "methodological reform" currently taking place in quantitative second-language (L2) research. In the first manuscript, the researcher describes an empirical investigation on the application of two well-known effect size estimators, eta-squared (eta…

Diversification trends of U.S. schools make clear the need for evidence-based practices supporting ethnically-racially diverse students. Yet, there are significant hindrances to readily identifying and summarizing findings generated from diverse classroom contexts. The current meta-analytic review was designed to address this gap in the classroom…

Situational Teaching plays a crucial role in English classroom teaching in Chinese Primary Schools; hence the relevant research prospers simultaneously. This study is devoted to reveal the research characteristic on English Situational Teaching in Primary Schools in the past 6 years. Result of contrastive analysis and survey of the essays…

A modification of the first stage of the standard procedure for two-stage meta-analytic structural equation modeling for use with large complex datasets is presented. This modification addresses two common problems that arise in such meta-analyses: (a) primary studies that provide multiple measures of the same construct and (b) the correlation…

Introduction: Pressed by the increasing social importance of digital information, including the current attention given to the "big data paradigm", several research projects have taken up the challenge to quantify the amount of technologically mediated information. Method: This meta-study reviews the eight most important inventories in a…

Impacts of incorporating active learning pedagogies into a lecture-based course were examined among 266 students across nine research methods course sections taught by one instructor at a large public university. Pedagogies evaluated include lecture only, lecture with small group discussions, and lecture with simulations. Although…

Background: Observation Studies, Unmeasured Confounding, and Sensitivity Analysis: An important part of educational research is identifying important, potentially causal, factors that influence children's learning from observational studies. However, it is well-known that discovering such factors from observational studies can be biased due to…

Rigorous scholarship is essential to the continued growth of group work, yet the unique nature of this counseling specialty poses challenges for quantitative researchers. The purpose of this proposal is to overview unique challenges to quantitative research with groups in the counseling field, including difficulty in obtaining large sample sizes…

As in many other social sciences, in international and comparative education there is an epistemological schism between two main approaches, one of which is traditional whose methodology and methods are historical-hermeneutical, while the other is empirical and oriented towards the natural sciences. In international and comparative education,…

This study determined the effect of matching children with specific language impairment (SLI) and their peers with typical development (TD) for nonverbal IQ on the IQ test scores of the resultant groups. Studies published between January 2000 and May 2012 reporting standard nonverbal IQ scores for SLI and age-matched TD controls were categorized…
