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…

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…

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…

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…

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,…

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…

Background: Educational research has been conducted mainly by using behavioural approaches. Whilst such methods provide invaluable insights into the field, several important questions such as 'how do we learn?' and 'what mechanisms cause individual differences?' cannot be answered thoroughly by using only behavioural approaches. In the last three…

"Beyond the Visual" is a survey of contemporary approaches to researching a wide range of visual and multimodal phenomena. Building on his earlier book, "Reading the Visual" [ED617673], Serafini shares resources for conducting multimodal research across the social sciences. Beginning with a comprehensive overview of the…

In the first edition of this book, Tim Stewart provided an easy-to-follow guide to conducting classroom research, from getting started to publishing your findings. The second edition of "Classroom Research for Language Teachers" further explores different approaches to conducting classroom research in the English language classroom,…

The study aimed to conduct a systematic literature review to identify the trends, impacts, and challenges of mobile microlearning (MML) research. Using five academic databases from the fields of social science, engineering, and medical science as search sources, 26 scholarly articles, published between 2015 and 2020, were retrieved. The study…

The increasing volume of large-scale assessment data poses a challenge for testing organizations to manage data and conduct psychometric analysis efficiently. Traditional psychometric software presents barriers, such as a lack of functionality for managing data and conducting various standard psychometric analyses efficiently. These challenges…

Biology education research provides important guidance for educators aiming to ensure access for disabled students. However, there is still work to be done in developing similar guidelines for research settings. By using critical frameworks that amplify the voices of people facing multiple forms of marginalization, there is potential to transform…

Systems for learning and producing knowledge, such as career and technical education (CTE), often reproduce inequities unless an equity-focused lens is used when designing, implementing, and evaluating programs. This framework presents guidance for conducting CTE research with an intentional focus on equity. Developed by the CTE Research Network's…

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