In this paper, we provide a conceptual framework of the central aspects of mathematical definitions discussed in the mathematics education literature. Based on a systematic literature review, we found that characterizations of definitions in the mathematics education literature can be classified into five main themes: requirements, preferred…

The current study reviewed the practice and application of social validity assessments in single-case design (SCD) studies within the field of school psychology. Social validity refers to the acceptability of intervention or program goals, procedures, and outcomes to educators, families, and students. Understanding the ways social validity is…

The "k"-means clustering method, while widely embraced in college student typology research, is often misunderstood and misapplied. Many researchers regard "k"-means as a near-universal solution for uncovering homogeneous student groups, believing its success hinges primarily on the selection of an appropriate "k."…

This systematic review aims to provide a complementary to existing synopses of the state-of-the-art of mathematics education research on "proof" and "proving" in both school and university mathematics. As an organizing framework, we used Cohen et al.'s triadic conceptualization of instruction, which draws attention not only to…

Active learning is a popular approach to teaching and learning that has gained traction through research on STEM educational improvement. There have been numerous university- and national/international-level efforts focused on transitioning courses from the lecture method to active learning. However, despite these large-scale changes, the active…

Introduction: The What Works Clearinghouse (WWC) reviews rigorous research on educational interventions with a goal of identifying "what works" and making that information accessible to educators and policymakers. In rating the quality of causal research, the WWC has historically prioritized internal validity over external validity. One…

This study provides a comprehensive overview of methodological aspects when using heart rate variability (HRV) measures in educational research. Following PRISMA 2020 guidelines, we searched four databases for relevant studies published until March 5, 2024. From the 48 studies reviewed, we extracted data across three analytical categories: (1)…

A systematic review was conducted to identify emergent trends in the assessment of secondary school climate. Comparisons of assessments published in the past 6 years (2016-2021) and those published prior to 2016 (total N = 46) revealed recent shifts related to conceptualization, validity, accessibility, and recommendations for improving school…

This systematic review investigated the topics studied and reporting practices of published meta-analyses in educational measurement. Our findings indicated that meta-analysis is not a highly utilized methodological tool in educational measurement; on average, less than one meta-analysis has been published per year over the past 30 years (28…

Many teacher education researchers have expressed concerns about the lack of rigorous impact evaluations of teacher preparation practices. I summarize these various concerns as they relate to issues of internal validity, measurement, and external validity. I then assess the prevalence of these issues by reviewing 166 impact evaluations of teacher…

Outside of education, many academic disciplines developed and promulgated checklists to evaluate the quality of qualitative studies. This article used an embedded mixed methods approach in three stages: development of a conceptual framework reviewing 62 guidelines; a content analysis of key areas of the guidelines; and review of dissertations to…

This article documents the results of a meta-analysis of available correlational validity evidence for the Social Skills Improvement System Performance Screening Guide (SSIS-PSG), which is a brief teacher-completed rating scale designed to be used as part of universal screening procedures. Article inclusion criteria included (a) published in…

Special education teachers' (SETs) working conditions play a crucial role in shaping the size, quality, and effectiveness of the U.S. SET workforce and thereby shape the quality of instruction provided to students with disabilities. Valid measures of SETs' working conditions are essential for conducting robust research on how to improve working…

Studies show that processes like teacher-child interactions are a key dimension of childcare quality and that global and domain-specific interactions seem to have different effects on child development. A variety of instruments have been used to assess quality in the field of early childhood research. The aim of this study was to identify and…

Background: The objective of this systematic review is to identify characteristics, trends, and gaps in measurement in Science, Technology, Engineering, and Mathematics (STEM) education research. Methods: We searched across several peer-reviewed sources, including a book, similar systematic reviews, conference proceedings, one online repository,…
