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…

The aim of this article is to discuss how to research into phenomena that no one wants to talk about: silenced and tabooed phenomena. With the outset in data culled in two research projects concerning student's conceptualization of small group learning, the article discusses methodology, theory, and ethics in researching into silenced and tabooed…

Background: A common critique of adventure education research methodology is the overreliance on pre-/post-study designs to measure change. Purpose: This paper compares and contrasts two methods of data analysis on the same adventure education data set to show how these distinct approaches provide starkly different results and interpretation.…

For this 15th iteration of the International Conference on Educational Data Mining (EDM 2022), the conference was held in Durham, England, with an online hybrid format for virtual participation as well. EDM is organized under the auspices of the International Educational Data Mining Society. The theme of this year's conference is Inclusion,…

We conducted a systematic review to identify randomized controlled trials (RCTs) and single case research design (SCRD) studies of children with autism spectrum disorder that evaluate the effectiveness of responsivity intervention techniques for improving prelinguistic and/or language outcomes. Mean effect sizes were moderate and large for RCTs…

Contemporary North-South research collaborations are fraught with power relations originating in colonialism. Debates about research ethics have tended to turn around the "procedural ethics" formal model and the "everyday ethics" practical model. We build on that to suggest a second debate that scrutinises ethics and power…

There are marked racial and ethnic disparities in diagnosis and services for individuals on the autism spectrum, yet race and ethnicity are underreported and underexamined in autism research. The current study examines the reporting of race and ethnicity and the inclusion of participants across racial and ethnic groups in studies included in a…

This guide will help researchers design and implement impact studies in education so that the findings are more generalizable to the study's target population. Guidance is provided on key steps that researchers can take, including defining the target population, selecting a sample of schools--and replacement schools, when needed--managing school…

Inquiry-based laboratories were implemented into a General Chemistry Laboratory sequence, and the impact of these exercises on students' experimental design skills was assessed using a four-part assessment developed for this study. This assessment contained a multiple-choice section, a section asking students to explain their reasoning behind a…

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…
