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…

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…

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 protocol guided the review of research that informs the What Works Clearinghouse (WWC) practice guide entitled "Strategies for Postsecondary Students in Developmental Education -- A Practice Guide for College and University Administrators, Advisors, and Faculty." This protocol was used in conjunction with the "WWC Procedures…

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…

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…

This case study provides an account of my research journey in one high school. It focuses on the practical issues that can arise when negotiating access. It also attends to the impact that unexpected transitions in the field can have when conducting research. Although ethical dilemmas emerge in multiple moments when conducting research, special…

In the fall of 2017, ACT began providing a limited number of supports (also known as accommodations) to English Learner (EL) students in the US taking the ACT® test. The goal of the supports is to remove construct-irrelevant variance in students' scores related to limited English proficiency and allow students to more accurately demonstrate their…

In this case, I describe the "Paths on Life's Way (Paths)" project. The "Paths" project is the only longitudinal study of its kind in British Columbia and one of the few longitudinal studies in Canada. The research, now spanning 22 years-with a 28-year follow-up underway-is designed to provide a detailed examination of the life…
