The issue of missing data raises concerns in all statistical and educational research. In this study, we focus on missing data in school-based assessment data generated by progressed high school learners (those who did not meet the promotional requirements for their current grades but were allowed to move to the next grade because of policy…

This colloquium brings information about a second cycle of OECD's International Early Learning and Well-being Study (IELS) to the early childhood community, and offers a further critique of the approach to comparative research that the IELS embodies.

When conducting a postal survey, a traditional recommendation is to use paper postage stamps instead of an automated postage system, to make sure that invitations have a more personal and attractive appearance. In this research note, we investigate whether this traditional recommendation is still valid. In the autumn of 2020, a postal survey was…

In this article, I present how I navigated unexpected apprehension that I faced while communicating with teacher participants during my PhD data collection (via interviews, observations and document study). I mediated the apprehension by strategies such as disclosing my teacher identity, expressing an interest in their practice and assuring them…

Well-being 2030 has become the latest rationale for the OECD's education work. This vision has given rise to new assessments of student well-being beginning with PISA 2015. The OECD, recognising the problems of PISA 2015, conceptualised a wider student well-being construct in PISA 2018, and attempted to measure 'students' feelings'. However,…

Much cultural capital research has accumulated since its inception in the 1970s and researchers have charted the corresponding development of cultural capital theory in academic communities. This empirical study takes the further step of offering an account of cultural capital as it is interpreted in schools. This 'interventionalist account' is…

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…

This paper presents the main methodological issues met with during the research on adolescent everyday life information behavior in the context of making informed decisions, which was carried out in Croatia from 2018 to 2020. It does not focus on the research results, but rather on the methodological issues and concerns that had occurred stemming…

This article extends recent attempts to think (post)qualitative research together with decolonial, postcolonial and other critiques -- as a frictional, fraught encounter. I review how the concept of voice has been used in past and present research with children and young people: from research speaking "about" children and young people,…

Student engagement plays a vital role in improving students' learning outcomes. Traditional educational assessments of engagement have many limitations, which undermine the understanding of the mechanisms by which engagement affects learning and broad educational practices that leverage engagement. Through a mixed-methods approach and multimodal…

This study shows that residual variation can cause problems related to scaling in exponential random graph models (ERGM). Residual variation is likely to exist when there are unmeasured variables in a model--even those uncorrelated with other predictors--or when the logistic form of the model is inappropriate. As a consequence, coefficients cannot…

School-based research presents ethical challenges, especially with respect to informed consent. The manner in which pupils and their parents respond to an invitation to participate in research is likely to depend on several factors, including the level of trust between them and the researchers. This paper describes our recruitment and consent…

As a result of the evidence-based decision-making movement, the number of randomized trials evaluating educational programs and curricula has increased dramatically over the past 20 years. Policy makers and practitioners are encouraged to use the results of these trials to inform their decision making in schools and school districts. At the same…

Causal effects are commonly defined as comparisons of the potential outcomes under treatment and control, but this definition is threatened by the possibility that either the treatment or the control condition is not well defined, existing instead in more than one version. This is often a real possibility in nonexperimental or observational…

The use of video recordings as a data source in qualitative research presents challenges when it comes to selecting time scales. Here, we discuss the implications of selecting time scales with regard to the interpretations and conclusions of a classroom event. The analysis draws on data from the PISA+ project, a large-scale video study of six…
