Research designs in which clusters are the unit of randomization are quite common in the social sciences. Given the multilevel nature of these studies, the power analyses for these studies are more complex than in a simple individually randomized trial. Tools are now available to help researchers conduct power analyses for cluster randomized…

The purpose of this study was to examine administrators' use of data, their perceptions of data, and what their expectations were in terms of teacher use of data. In conjunction with this examination will be a closer look at the new Professional Standards for Educational Leaders (PSEL) to determine the connections as well as the disconnections to…

"Fashioning Circuits" is a humanities course designed to explore how fashion, electronics, social issues, and makerspaces interact with design and critical theory. Digital humanities scholars and practitioners have seen an emergence of public art and representation beyond the academy, specifically applying interdisciplinary university…

The "Q" test is regularly used in meta-analysis to examine variation in effect sizes. However, the assumptions of "Q" are unlikely to be satisfied in practice prompting methodological researchers to conduct computer simulation studies examining its statistical properties. Narrative summaries of this literature are available but…

Educational research literature on mathematical modelling is extensive. However, not much attention has been paid to empirical investigations of its scholarly knowledge from the perspective of didactic transposition processes. This paper reports from an interview study of mathematical modelling activities involving nine professional model…

Computer-assisted instruction (CAI) resolved the ambivalence of computers in favor of potentials aligned with organizational and pedagogical features of distance education. This "coding" of educational computing confirmed critical appraisals that identified computers with commercialization, commodification, and deskilling. But where…

Recently, both sociology of science and policy research have shown increased interest in scientific uncertainty. To contribute to these debates and create an empirical measure of scientific uncertainty, we inductively devised two systems of classification or ontologies to describe scientific uncertainty in a large corpus of food safety risk…

The use of multimedia has often been suggested as a teaching tool in foreign language teaching and learning. In foreign language education, exciting new multimedia applications have appeared over the last years, especially for young learners, but many of these do not seem to produce the desired effect in language development. This article looks…

Creating explanations is an important process for students, not only to make connections between novel information and background knowledge, but also to be able to communicate their understanding of any given topic. This article explores students' explanations in the context of computational science and engineering, an important interdisciplinary…

This paper, authored in collaboration with researchers from Harvard University's Center for Education Policy Research and the Massachusetts Institute of Technology, reviews findings from a randomized controlled trial (RCT) at a partner school, focused on understanding the effects of a direct-to-student intervention on students' mindfulness…

School discipline has traditionally endorsed the use of exclusionary practices (i.e. suspension and expulsion). Such practices can have a negative short- and long-term impact on student lives, and tend to be enforced disproportionately with certain student populations. Although public school discipline policies have received increased scrutiny in…

There is a growing understanding of the unique ways that tabletops support effective collaboration; however, this research mostly focuses on environments in which learners work towards a single shared goal. Underpinning this perspective, either implicitly or explicitly, is the theory that collaborative learning is a process of attaining convergent…

Researchers in group counseling often encounter complex data from individual clients who are members of a group. Clients in the same group may be more similar than clients from different groups and this can lead to violations of statistical assumptions. The complexity of the data also means that predictors and outcomes can be measured at both the…

Historically, first language acquisition research was a painstaking process of observation, requiring the laborious hand coding of children's linguistic productions, followed by the generation of abstract theoretical proposals for how the developmental process unfolds. Recently, the ability to collect large-scale corpora of children's language…

Moral identity research to date has largely failed to provide evidence for developmental trends in moral identity, presumably because of restrictions in the age range of studies and the use of moral identity measures that are insensitive to age-related change. The present study investigated moral identity motivation across a broad age range (14-65…
