The synthetic control method (SCM) is a popular approach for estimating the impact of a treatment on a single unit with panel data. Two challenges arise with higher frequency data (e.g., monthly versus yearly): (1) achieving excellent pre-treatment fit is typically more challenging; and (2) overfitting to noise is more likely. Aggregating data…

This paper aims to explore the philosophical theoretical foundations of two basic research paradigms, namely positivism and interpretivism. In the discussion process, literature in the relevant fields including academic papers and books is reviewed and used as support for the analysis. Firstly, the paper explores the differences between the…

Drawing from sociological and economic analyses of gender and work, this column explores issues of occupational gender segregation, privilege, and devaluation. Comparisons are made with increased female achievement at all levels in postsecondary education. The questions are then raised: If cultural devaluation of women and activities remains…

While "Rebecca" is not currently a set text for A-Level English Literature, this paper argues that the novel's multi-faceted richness would justify its inclusion in any list of recommended texts. Divided into four interconnected parts, the paper offers, firstly, some approaches to the reading and teaching of fiction, generally. The…

The purpose of this ITEMS module is to provide an introduction to differential item functioning (DIF) analysis using mixture item response models. The mixture item response models for DIF analysis involve comparing item profiles across latent groups, instead of manifest groups. First, an overview of DIF analysis based on latent groups, called…

Conventional wisdom suggests that evangelical Christians, often among the most vocal advocates of school choice efforts in the U.S., are promoting choice out of a sense of frustration with public schools and perceived bias against religion. Research by Marilyn Anderson Rhames, however, suggests that evangelicals are no more concerned about…

This paper investigates the production of space and language policy in Ras Al Khaimah, a city in the United Arab Emirates. The paper builds on recent work in socio- and applied linguistics that has made use of sociospatial concepts from human geography. It argues that researchers should not only investigate space as a factor structuring language…

Background: Stratified medicine seeks to identify patients most likely to respond to treatment. Individual participant data (IPD) network meta-analysis (NMA) models have greater power than individual trials to identify treatment-covariate interactions (TCIs). Treatment-covariate interactions contain "within" and "across" trial…

Background: Observation Studies, Unmeasured Confounding, and Sensitivity Analysis: An important part of educational research is identifying important, potentially causal, factors that influence children's learning from observational studies. However, it is well-known that discovering such factors from observational studies can be biased due to…

Small-study effects are a common threat in systematic reviews and may indicate publication bias. Their existence is often verified by visual inspection of the funnel plot. Formal tests to assess the presence of funnel plot asymmetry typically estimate the association between the reported effect size and their standard error, the total sample size,…

Fuzzy-set qualitative comparative analysis (fsQCA) has become one of the most prominent methods in the social sciences for capturing causal complexity, especially for scholars with small- and medium-"N" data sets. This research note explores two key assumptions in fsQCA's methodology for testing for necessary and sufficient…

Historical events in Arizona, including very recent ones, are eerily similar to those of Rwanda. In this article, stories of Arizona's political history are relayed while recalling those leading to Rwanda's genocide. The stories include references to key roles education policy has played in the oppression of students labeled Tutsi and students…

We argue that 'academic language' should not be understood as technical components associated with a 'register', and that instead we must attend to its enregisterment. Enregisterment relies upon language ideologies and models of personhood, requiring attention to social components of 'academic language' beyond lexico-grammar. We draw on…

This qualitative multiple case study assesses two locally designed instructional artifacts created to support teacher enactment of culturally relevant educational (CRE) practices. Attention is paid to artifact's ability to support collective teacher use of CRE and the ways that artifacts acted as proxies for instructional leadership. Findings…

We give attention to the racial contexts of mathematics education in Colombia and the USA. We discuss the particularities of these contexts but also explore the how in both contexts Blackness and Black people are relegated to the lower rungs of the social order. In offering this comparative analysis, we call for expanded research on race, racism,…
