Given the prevalence of social network sites (SNS) uptake among college students, and Facebook use in particular, we seek to understand the variety of ways in which Facebook is embedded in the routine, everyday lives of undergraduates. In addition to Facebook use, we aim to shed light on non-use; why do some American undergraduates choose to use…

This commentary discusses the implication of child and adolescent development research for public policy in Latin America. As illustrated by the articles in this special issue, even though the research of child and adolescent development in Latin America is making significant progress, still more research is needed. Developmental research in the…

Families and schools are important environments that contribute to the resilience and positive development of preadolescent children. Sense of mastery, including its two central factors of optimism and self-efficacy, forms an important component of resilience during preadolescence (Prince-Embury, 2007). This study examined the interrelationships…

The main purposes of this study were to develop bi-factor multidimensional item response theory (BF-MIRT) observed-score equating procedures for mixed-format tests and to investigate relative appropriateness of the proposed procedures. Using data from a large-scale testing program, three types of pseudo data sets were formulated: matched samples,…

The aim of this article is to present arguments for an integrated empirical research on teaching and learning based on previous research and the phenomenographic research tradition. From 1970 and for some years after, the main focus in phenomenographic research was on students' approaches to and understanding of subject matter. Later, based on…

This conversation explores emerging debates concerning teaching to and about marginalized populations often left out of "representative" data sets. Based on our experiences studying, teaching, and belonging to some of these unrepresented populations, we outline some strategies sociologists may use to transform the limitations of data…

The goal of this paper is to present a framework of researcher knowledge development in conducting a study in mathematics education. The key components of the framework are: knowledge germane to conducting a particular study, processes of knowledge accumulation, and catalyzing filters that influence a researcher's decision making. The components…

Becoming more scholarly can be challenging for many in the academy, including for those transitioning from professional roles. This paper presents the initial findings of an ongoing action research project that set out to explore and develop aspects of identity among a group of Australian occupational therapy academics. Thirteen participants…

Heterogeneity in response styles can affect the conclusions drawn from rating scale data. In particular, biased estimates can be expected if one ignores a tendency to middle categories or to extreme categories. An adjacent categories model is proposed that simultaneously models the content-related effects and the heterogeneity in response styles.…

This study determined the effectiveness of an experimental emergent literacy intervention, targeting teenage mothers attending an educational facility. Using a pretest/posttest research design, 27 participants completed a 7­-week intervention based in the classroom, targeting a range of emergent literacy skills that they could utilize when reading…

A new variant of the iterative "data = fit + residual" data-analytical approach described by Mosteller and Tukey is proposed and implemented in the context of item response theory psychometric models. Posterior probabilities from a Bayesian mixture model of a Rasch item response theory model and an unscalable latent class are expressed…

Advances in multilevel modeling techniques now make it possible to investigate the psychometric properties of instruments using clustered data. Factor models that overlook the clustering effect can lead to underestimated standard errors, incorrect parameter estimates, and model fit indices. In addition, factor structures may differ depending on…

The aim of this study was to explore the different ways in which a number of Chilean stakeholders conceptualise the "good early childhood educator" in Chile. In a context where new foreign narratives are increasingly dominating the field and the recent standardisation of the educators' professional role is being implemented, this…

This special issue is dedicated to understanding how to best support positive educational outcomes for all students. While reading strategies, course design and methods, testing and assessment, and a variety of other factors are all integral to L2 reading outcomes, policies constructed at the federal, state, district, and school level play an…

This article describes how the authors began a science, technology, engineering, art, and math (STEAM) collaboration and completed three projects of varying complexity in their art and chemistry classrooms. The projects align with the Next Generation Science Standards (NGSS Lead States 2013).
