This systematic review examines how preservice teachers' (PSTs) domain-specific epistemological beliefs (EB) are studied and understood within initial teacher education (ITE) with attention to theoretical, contextual, and methodological aspects. Findings from 24 empirical studies published up to 2024 were synthesized. The review analyzed…

Well-chosen covariates boost the design sensitivity of individually and cluster-randomized trials. We provide guidance on covariate selection generating an extensive compilation of single- and multilevel design parameters on student achievement. Embedded in psychometric heuristics, we analyzed (a) covariate "types" of varying…

Data donation is a novel approach to collecting digital trace data, where users are asked to download their retrospective data from a platform and share them with the researchers. Little is known about the willingness to donate data and the potential bias that may arise from nonparticipation. We conducted a study among over 900 German Facebook…

Mailing campaigns are a way to keep longitudinal survey respondents engaged. While mailings usually include a survey answer request, sometimes respondents are contacted between-waves to update contact information or simply to keep respondent contact. Research on the actual impact of these between-wave contacts on response rates is scarce. This…

This study explores how qualitative health researchers navigate the demands of medical research ethics committees in Germany where qualitative research is subject to approval only when it is conducted in medical contexts. We present the results of a grounded theory study to investigate qualitative health researchers' experiences with procedural…

This paper explores the personal experiences of Sandra Kaire as a postdoctoral researcher who worked with Margaret Somerville in relation to methodological approaches. The ideas were initially developed in consultation when Sandra worked together with Margaret at Western Sydney University, Australia. The paper explores Sandra's personal…

Processes that unfold over individuals' life courses are often associated with inequalities later in life. The literature lacks methodological approaches to analyze inequalities in outcomes between groups, for example, between women and men, in a life-course-sensitive manner. We propose a combination of methods--of sequence analysis, which enables…

In less than a decade, conflicts have driven two massive waves of refugees to the European Union, mainly from Syria and Ukraine but not only. Many of these refugees are children whose education has been disrupted. This article aims to identify the elements that foster school success for migrant and refugee children in their host societies. To…

Probes are follow-ups to survey questions used to gain insights on respondents' understanding of and responses to these questions. They are usually administered as open-ended questions, primarily in the context of questionnaire pretesting. Due to the decreased cost of data collection for open-ended questions in web surveys, researchers have argued…

This study uses an education in emergencies (EiE) lens and a scientometric approach to examine the educational research landscape during the COVID-19 pandemic by analyzing 95,628 publications indexed in the Web of Science Core Collection database from 2020 to February 2023. It employed descriptive and network approaches to map growth trajectory,…

Research Findings: Prosocial behavior in early childhood can be assessed by various informants and methodologies, but the information each provides may differ in meaningful ways. The present study measured and compared young children's (N = 486; age: M = 48.51 months, SD = 8.22) prosocial behavior based on parent reports, teacher reports, and…

At present, there are relatively few international studies that reflect research in religious didactics from a metatheoretical perspective. Against this background, the fundamental question of this contribution is whether there are research designs that are typical for research in religious didactics. For this purpose, research was conducted for a…

Public speaking often imposes a nerve-wracking atmosphere in the L2 classrooms. Consequently, an alternative to the anxiety-arousing activity by using advanced technology for pedagogy is urgent. Prior publications reported the use of virtual reality (VR) for training public speaking and alleviating students' public speaking anxiety (PSA). However,…

Recent years have seen a growing number of studies investigating the accuracy of nonprobability online panels; however, response quality in nonprobability online panels has not yet received much attention. To fill this gap, we investigate response quality in a comprehensive study of seven nonprobability online panels and three probability-based…

In a mixed-methods study on poverty in Germany, we conducted qualitative interviews and collected quantitative data on ego-centered networks using a name-generator approach and a single set of respondents. Based on the qualitative data, we first developed a typology of negative ties and then evaluated which of these ties the name generator (on…
