A priori power analyses allow researchers to estimate the number of participants needed to detect the effects of an intervention. However, power analyses are only as valid as the parameter estimates used. One such parameter, the expected effect size, can vary greatly depending on several study characteristics, including the nature of the…

As intersectionality gains more prominence, scholars still face difficulties of incorporating principles of intersectionality into empirical research. Key concepts of intersectionality theory include moving away from additive thinking, relationality, and social constructionism. An important challenge is how to incorporate these concepts into…

With questions about what it means to conduct educational research in Indigenous contexts based on reciprocal relationships, we review key contributions to the literature from Indigenous and qualitative methodologists. We identify four dimensions of reciprocity, extending the notion of reciprocity as transaction or compensation. To design research…

Single-case designs are a class of repeated measures experiments used to evaluate the effects of interventions for small or specialized populations, such as individuals with low-incidence disabilities. There has been growing interest in systematic reviews and syntheses of evidence from single-case designs, but there remains a need to further…

This scoping review addresses peer-reviewed research on musical interaction with children and young people with severe/profound intellectual and multiple disabilities (S/PIMD). Twenty-five articles published between the years 2000 and 2020 met the inclusion criteria. A narrative synthesis was used to summarise and evaluate different features,…

Professional development for teachers is regarded as one of the principal pathways through which we can understand and cultivate effective teaching and improve student outcomes. A critical component of studies that seek to improve teaching through professional development is the detailed assessment of the intermediate teacher development processes…

In most STEM instruction, students interact with visual representations, which can be presented in either in a physical or a virtual mode or in a blended form that combines both modes. While much research has compared the effects of physical and virtual representations on students' learning, the field is far from being able to predict when and why…

We initiated and structured a single program that supervised teachers, some with neuroscience or psychology degrees, to collaborate and explore the effects of science of learning-translated pedagogy. This article reports on the 34 findings from teacher-led randomized controlled trials (RCTs) and replications. Teachers designed trials, looking at…

Public school districts have been operating under a decade's long press to move beyond functioning as engines of access-oriented mass public schooling to functioning as instructionally focused education systems pursuing educational excellence and equity. This press has researchers developing analytic frameworks useful for examining different ways…

Computer vision algorithms have made tremendous advances in recent years. We now have algorithms that can detect and recognize objects, faces, and even facial actions in still images and video sequences. This is wonderful news for researchers that need to code facial articulations in large data sets of images and videos, because this task is time…

Biomedical research policy in many countries has adopted the principle of active involvement in research. However, how different approaches to involvement such as patient and public involvement/engagement (PPIE), qualitative research, participatory research, co-design and co-production sit alongside each other, is contentious and unclear. There…

Researchers have explored a variety of topics related to identifying and distinguishing among specific types of rater effects, as well as the implications of different types of incomplete data collection designs for rater-mediated assessments. In this study, we used simulated data to examine the sensitivity of latent trait model indicators of…

This integrative literature review takes up the ongoing discussion about the place of mixed methods designs in educational research. We focus on studies that investigate the role of argumentation in inquiry-based learning, either as a means for enhancing inquiry (argument-based inquiry) or as a learning outcome (inquiry-based argument). We argue…

The struggle to cast a net around the numerous ways prosocial behavior is expressed lends itself to the absence of widely accepted methods of measurement. Additionally, research intent on evaluating the psychometric properties of current approaches has been somewhat limited. Weaving together seminal as well as contemporary research, the current…
