Evaluators of education interventions are increasingly designing studies to detect impacts much smaller than the 0.20 standard deviations that Cohen characterized as "small." While the need to detect smaller impacts is based on compelling arguments that such impacts are substantively meaningful, the drive to detect smaller impacts may…

Researchers' reliance on using mixed methods for in-depth understanding of a phenomenon is on a rise. This review provides a synthesis of studies using Mixed Methods Research (MMR) approach in the field of instructional design, with a particular focus on research questions. The results show that of the 752 articles published on MMR in the…

Calls to transform introductory college physics courses to include scientific practices require assessments that can measure the extent to which these transformations are effective. Such assessments should be able to measure students' abilities to intertwine important concepts with practices in which scientists engage. In addition to evaluating…

This study examines the epistemic disciplinary knowledge that students consider when addressing a real food emergency that requires their engagement in inquiry and argumentation practices. The study comprised two phases: (1) designing an experiment to study the emergency and (2) evaluating the real outcome of the emergency. The participants were…

Concept maps have been used widely in various subjects of K-12 and higher education for diverse purposes. Digital concept maps (DCM) provide even more benefits, such as higher efficiency, expanded canvas, and multimedia integration. The present paper sought to analyze the research and application trends and issues in DCM research and practices…

In randomized control trials (RCT), the recent focus has shifted to how an intervention yields positive results on its intended outcome. This aligns with the recent push of implementation science in healthcare (Bauer et al., 2015) but goes beyond this. RCTs have moved to evaluating the theoretical framing of the intervention as well as differing…

One major challenge researchers have faced during the disruptions resulting from the COVID-19 pandemic is how to adapt to the global virus and, at the same time, make good progress in their research pursuits. Also, many international researchers have suspended ongoing research in developing countries due to inadequate online facilities in these…

Although there is a notion of a 'Nordic tradition' of outdoor education in the international literature, research from the Nordic countries is rarely included in research reviews. Therefore, this scoping review provides an overview of empirical studies on outdoor education (grades 1-13) from the Nordic countries. Of the 586 hits, 52 studies met…

For researchers seeking to improve education, a common goal is to identify teaching practices that have causal benefits in classroom settings. To test whether an instructional practice exerts a causal influence on an outcome measure, the most straightforward and compelling method is to conduct an experiment. While experimentation is common in…

'QuantCrit' (Quantitative Critical Race Theory) is a rapidly developing approach that seeks to challenge and improve the use of statistical data in social research by applying the insights of Critical Race Theory. As originally formulated, QuantCrit rests on five principles; 1) the centrality of racism; 2) numbers are not neutral; 3) categories…

Two studies regarding the graphic display of single case data are presented. First, measurement and graphical display of data from studies in highly-ranked journals in special education were assessed. Measurement of desirable behaviors rather than undesirable behaviors was common and most studies used sessions and percentages as x and y-values,…

Professional development in teaching is a critical component of ongoing work to improve student learning outcomes in higher education, especially STEM education. While there are many large-scale professional development programs designed to help participants change the way STEM is taught, few have thoroughly evaluated the outcomes to determine…

Propensity score analysis is a statistical method that balances pre-existing differences across treatment conditions achieving a similar condition as randomization and thus, allowing the estimation of causal effects in non-randomized experimental designs. The four stages in propensity score analysis are (1) propensity score estimation, (2)…

Background: When well-designed and implemented, cluster randomized trials can meet the high standards federal agencies and other funders increasingly require for evidence on the effectiveness of school health programs and services. However, designing and implementing these studies can present more challenges than at first appears. Methods: I…

Purpose: Measuring change is a common goal in clinical research, and comparing nonequivalent groups is sometimes a necessity in this context. Yet, evaluating change in this way can be problematic, and little consensus is reported on the best way to conduct such an evaluation. This tutorial presents the process of planning a clinical study designed…
