This paper describes a content analysis used to examine educational doctoral degrees (EdD) dissertations in a U.S. university. The purpose of the study was to get a better understanding of the validation techniques utilized in dissertations published by EdD students. Forty-nine dissertations were selected and examined for research methodologies,…

This article considers the challenges of using artificial intelligence (AI) and machine learning (ML) to assist high-stakes standardised assessment. It focuses on the detrimental effect that even state-of-the-art AI and ML systems could have on the validity of national exams of secondary education, and how lower validity would negatively affect…

Purpose: This paper illustrates how Guba and Lincoln's parallel criteria for establishing trustworthiness, can be adapted and applied to qualitative research on indigenous social protection systems. It provides insights for social protection researchers, exploring plausible qualitative research rigor evaluation criteria, on plausible alternatives.…

Students frequently turn to the internet for information about a range of scientific issues. However, they can find it challenging to evaluate the credibility of the information they find, which may increase their susceptibility to mis- and disinformation. This exploratory study reports findings from an instructional intervention designed to teach…

While people's proclivity toward congenial partisan media has been well documented, methods of resistance are less researched. This study explores the congenial media effect, the phenomenon of our gravitation to and acceptance of like-minded media, and whether a media literacy intervention can mitigate people's acceptance of ideologically…

A community of practice (CoP) is a vehicle for bringing in participants who share a common interest to learn from and grow with each other. In order to have a transformative learning experience, the CoP needs to be facilitated by a humble, credible facilitator. This article examines the role and benefits of a humble, credible facilitator and how…

Many of the resources developed to promote the use of evidence in policy aspire to an ideal of rational decision making, yet their basis in the decision sciences is often unclear. Tracing the historical development of evidence-informed policy to its roots in "evidence-based medicine" (EBM), we distinguish between two understandings of…

Tolerance intervals provide a bracket intended to contain a percentage (e.g., 80%) of a population distribution given sample estimates of the mean and variance. In random-effects meta-analysis, tolerance intervals should contain researcher-specified proportions of underlying population effect sizes. Using Monte Carlo simulation, we investigated…

Missing data in scientific research go hand in hand with assumptions about the nature of the missingness. When dealing with missing values, a set of beliefs has to be formulated about the extent to which the observed data may also hold for the missing parts of the data. It is vital that the validity of these missingness assumptions is verified,…

Nonprobative but related photos can increase the perceived truth value of statements relative to when no photo is presented ("truthiness"). In two experiments, we tested whether truthiness generalizes to credibility judgments in a forensic context. Participants read short vignettes in which a witness viewed an offence. The vignettes were…

Studies of the grant proposal tend to conflate academic research grant proposals with other kinds of nonprofit grant proposal genres, even though research and nonprofit grant proposals have different audiences and goals. To address this gap, this study draws on the Aristotelian concept of "topoi" (or typical arguments) and uses corpus…

This study explores transformative experiences in university physics education and their potential to contribute to Bildung through a case study based on interview data of six Norwegian master's physics students. The results show that the students experience becoming more skeptical and critical in different ways, and while not solely ascribing…

Objective: This study aimed to evaluate how health educators use emotional appeals on the social media site TikTok to promote well-being, engage audiences and reduce mental health stigma. Design/Method: Our research team conducted a quantitative content analysis of 400 TikTok videos centred on health education. We evaluated the frequency of mental…

There is tension about teachers' professional use of social media platforms, such as Pinterest, to access instructional resources for teaching science. Teachers' frequent use of Pinterest signals their perceived value despite concerns about the quality of the resources found there. These resources can constitute a part of teachers' network of…

The field of science education has long advocated for students to leave K-12 education with an appreciation for the diversity of research methods scientists employ in order to effectively engage with research generated across many scientific fields of study. Yet, research has indicated that students typically believe research proceeds according to…
