This article reviews the origins and use of the terms quasi-experiment and natural experiment. It demonstrates how the terms conflate whether variation in the independent variable of interest falls short of random with whether researchers find, rather than intervene to create, that variation. Using the lens of assignment--the process driving…

Game designers and researchers have sought to create gameful environments that consider user preferences to increase engagement and motivation. In this sense, it is essential to identify the most suitable game elements for users' profiles. Designers and researchers must choose strategies to classify users into predefined profiles and select the…

Education researchers often encounter scenarios where an abrupt policy change occurs within or across jurisdictions or populations that affect key student outcomes. Difference-in-differences is a research design analysts can use to estimate causal effects of these "natural experiments." This article introduces education researchers to…

The What Works Clearinghouse (WWC) identifies existing research on educational interventions, assesses the quality of the research, and summarizes and disseminates the evidence from studies that meet WWC standards. The WWC aims to provide enough information so educators can use the research to make informed decisions in their settings. This…

This paper puts forward a research agenda in the area of explicit and implicit knowledge and learning of second or additional languages. Based on a brief overview of reliable findings as well as open questions in the field, three agenda items are highlighted. First, valid and reliable measures of explicit and, in particular, implicit knowledge and…

For some time now, the arts education community has designed for broader outcomes for youth. These programs intentionally foster not only youth achievements within the arts or academics, but also youth and community thriving--through outcomes such as youth civic engagement, occupational identities, and wellness. In this report, the authors seek to…

Primary sources are the foundations of historical research because they are artifacts representing first-hand accounts or connections to the event, time, or place being investigated. The reality is that many IDT researchers do not have training in historical source analysis, nor do many researchers know where to find primary sources in the field…

It has quickly become apparent in the past year that online learning is not only an asset, but it is critical to the continued education of youth during times of crisis. However, districts and schools across the nation are in need of guidance and practical, research-backed approaches to distance and hybrid learning. The current COVID-19 crisis has…

Sample size and statistical power are important factors to consider when planning a research synthesis. Power analysis methods have been developed for fixed effect or random effects models, but until recently these methods were limited to simple data structures with a single, independent effect per study. Recent work has provided power…

Experimental designs in the social sciences have received increasing attention due to their power to produce causal inferences. Nevertheless, experimental research faces limitations, including limited external validity and unrealistic treatments. We propose combining qualitative fieldwork and experimental design iteratively--moving back-and-forth…

Virtual Reality (VR) is rapidly gaining popularity as a consumer technology, yet accessibility has not been prioritized. VR enables users to interact with immersive virtual worlds, but effective interaction requires the ability to perceive and navigate the environment. Fortunately, over the past thirty years, hundreds of scene-viewing and…

Media and Information Literacy (MIL) is one of the most important issues in today's mediatized world. Under the leadership of UNESCO, many international organizations in the world, as foreign donors, annually announce many projects and grants for the promotion and development of the field of MIL in the countries of the world. One of the main…

CADRE interviewed researchers to learn about their most effective strategies for recruiting and retaining participants for STEM education research. While there are no shortcuts to successful recruitment, a sustained commitment to understanding and addressing the needs of a district and its teachers is key to long-term success. In this new brief,…

There is a broad impetus across policy and institutional domains to expand public engagement and involvement with emerging technology research and innovation. Yet innovative theory, methods, and practices to critically explore algorithmic system controversies and democratic possibilities are still in nascent form. In this paper, we bring together…

This article delineates the process through which a quantitative study in the context of Pakistan was adapted into emergent mixed methods research due to COVID-19-related complexities. The in-process data collection was halted abruptly as schools were closed and lockdowns were imposed across Pakistan in the early 2020s due to COVID-19. In…
