Pre-registration refers to the practice of researchers preparing a time-stamped document describing the plans for a study. This open research tool is used to improve transparency, so that readers can evaluate the extent to which the researcher adhered to their original plans and tested their theory appropriately. In the current study, we conducted…

Mathematical representation is one of the skills that students need to master because it can help them in various problem-solving tasks. This research is a literature review of articles related to mathematical representation in mathematics education. The articles are those published in journals indexed by Scopus from 2020 to 2024. The results of…

This article's author describes an upper-level economics course that introduces students to experimental economics. The course, built around a term-long project requiring students to develop experiments in small groups, has two main objectives: (1) solidify students' learning of key economic concepts, and (2) introduce students to experimental…

Optimizing collaborative behavior is crucial in educational activities, directly improving academic performance, social skills, and social-emotional learning for both teachers and students. In an effort to decipher the mechanisms underlying the effectiveness of collaborative learning, educators and neuroscientists have initiated the collection and…

Although quality guidelines for single-case intervention research emphasize the importance of concurrent baselines in multiple-baseline and multiple-probe designs, nonconcurrent variations on these designs persist in the research literature. This study describes a systematic review of special education intervention studies (k = 406) between 1988…

Meta-analyses play an instrumental role in informing second language (L2) theory and practice. However, current (i.e., classic) approaches to meta-analysis are limited in their ability to do so because they often fail to capture the complexity inherent in primary studies' research designs. As we argue in this article, when complex L2 studies are…

In the realm of education, there has been an increasing emphasis on developing analytical thinking (AT) in the past few years. This systematic review focuses on an analysis of journal publications that have explored AT within the context of science, technology, engineering and mathematics (STEM) education. This analysis investigated four primary…

Evaluation designs seek to provide evidence of impact and collect formative data to understand and improve programs and inform decisions. Formative data is commonly used at the onset of developing a new program to modify and improve before full implementation. However, formative data is often collected throughout the life of the program to shape…

Social withdrawal has been a topic of interest in the field of developmental psychology for many decades. However, researchers have yet to systematically examine the historical trends in social withdrawal research. To honor the 70th anniversary of "Merrill-Palmer Quarterly," this systematic scoping review maps the changes in social…

This article discusses how the design of research should follow the questions the study seeks to address. The article provides practical and diverse examples of broad research questions applicable to researchers or program architects and summarizes how different methods should be employed to respond.

Mediation analysis in Single Case Experimental Designs (SCEDs) evaluates intervention mechanisms for individuals. Despite recent methodological developments, no clear guidelines exist for maximizing power to detect the indirect effect in SCEDs. This study compares frequentist and Bayesian methods, determining (1) minimum required sample size to…

When designing cluster-randomized trials (CRTs), one important consideration is determining the proper sample sizes across levels and treatment conditions to cost-efficiently achieve adequate statistical power. This consideration is usually addressed in an optimal design framework by leveraging the cost structures of sampling and optimizing the…

Researchers have studied the efficacy of motivational interviewing over the past 30 years. While it is recognized as a highly effective approach overall, variability in outcomes studies is largely attributed to the extent to which it is implemented with fidelity. MI applications in school have become increasingly popular in the past 10 years, yet…

This systematic review examines how preservice teachers' (PSTs) domain-specific epistemological beliefs (EB) are studied and understood within initial teacher education (ITE) with attention to theoretical, contextual, and methodological aspects. Findings from 24 empirical studies published up to 2024 were synthesized. The review analyzed…

The Cochrane Rapid Review Methods Group (RRMG) first released interim guidance in March 2020 to support authors in conducting rapid reviews (RRs). The objective of this mixed-methods study was to assess the adherence and investigate authors' understanding of the RRMG guidance. We identified all documents citing the Interim Cochrane RRMG guidance…
