The process of pairing a name with representations or peculiar properties permeates many mathematics classroom situations. In school, many practices go under the label 'definition', even though they can be very different from what mathematicians conceive as a formal definition, and in fact there are substantial differences between these different…

The puzzle of how to connect research with policy and practice is a vital area for scientific inquiry. The William T. Grant Foundation believes that attempts to improve the use of research evidence in policy and practice should be subject to rigorous theory building and empirical analysis. The stakes are high for the research community: If we do…

This study investigates the performance of robust maximum likelihood (ML) estimators when fitting and evaluating small sample latent growth models with non-normal missing data. Results showed that the robust ML methods could be used to account for non-normality even when the sample size is very small (e.g., N < 100). Among the robust ML…

Hofmann and Holm's (2019) recent survey on issues of research misconduct with PhD graduates culminated with a notable conclusion by the authors: 'Scientific misconduct seems to be an environmental issue as much as a matter of personal integrity'. Here, we re-emphasise the usefulness of an education-based countermeasure against toxic research…

An increased focus on transparency and replication in science has stimulated reform in research practices and dissemination. As a result, the research culture is changing: the use of preregistration is on the rise, access to data and materials is increasing, and large-scale replication studies are more common. In this article, I discuss two…

There is increased use of Bayesian networks (BN) in educational assessment. In psychometrics, BN serves as a measurement model with high flexibility, suitable to model educational assessment data with a complex structure. BN is a novel psychometric approach and not all aspects of its application are well-known. The article aims to provide the…

The perspective of people with dementia, particularly late-stage dementia, is often excluded from research, even from methods like Participatory Action Research (PAR), which aim to democratise research. This research note outlines how a PAR project engaged with the perspective of people with late-stage dementia in a residential aged care facility.…

We develop a structural after measurement (SAM) method for structural equation models (SEMs) that accommodates missing data. The results show that the proposed SAM missing data estimator outperforms conventional full information (FI) estimators in terms of convergence, bias, and root-mean-square-error in small-to-moderate samples or large samples…

Education researchers are increasingly interested in applying data mining approaches, but to date, there has been no overarching exposition of their methodological advantages and disadvantages to the field. This is partly because the use of data mining in education research is relatively new, so its value and consequences are not yet well…

This study explored the challenges faced by doctoral students in preparing and publishing research in reputable international journals. A descriptive qualitative approach was employed to gather in-depth information from four doctoral students in three higher education institutions in Sumatra, Indonesia. The participants were recruited through…

This research focused on the context of educational leadership, which sought to explore the possibilities of leadership opportunities for students with disabilities in a Malaysian secondary school. We utilized a phenomenological case study approach. We were keen on exploring this niche area as often leadership opportunities for students with…

Surveys of egocentric networks are especially vulnerable to methods effects. This study combines a true experiment--random assignment of respondents to receive essentially identical questions from either an in-person interviewer or an online survey--with audio recordings of the in-person interviews. We asked over 850 respondents from a general…

Transactional validity, a common approach in participatory research, is attained when preliminary analyses of research results are discussed with research participants and their feedback is incorporated in the analysis. Member checking is one way of achieving transactional validity, which has been heralded as a stronger version of validity reached…

Randomised trials are often funded by commercial companies and methodological studies support a widely held suspicion that commercial funding may influence trial results and conclusions. However, these studies often have a risk of confounding and reporting bias. The risk of confounding is markedly reduced in meta-epidemiological studies that…

This article focuses on an investigation of English as a Foreign Language (EFL) teacher (de)motivation in Spain which underwent a methodological transformation from mixed methods to a qualitative approach. Unexpected statistical results from the questionnaire in the piloting phase led to the creation of interview prompts, a dynamic data collection…
