This article offers an approach to examining differential item functioning (DIF) under its item response theory (IRT) treatment in the framework of confirmatory factor analysis (CFA). The approach is based on integrating IRT- and CFA-based testing of DIF and using bias-corrected bootstrap confidence intervals with a syntax code in Mplus.

Textbooks are primary teaching aids, sources from which students obtain knowledge of science domain. Due to this fact, curriculum developers in the field emphasize the crucial role of analysing the contents of science textbooks in improving science education. Scientific domain knowledge relies on graphical representations for the manifestation of…

Using queer theories of sexuality and gender, this study centers on "coming out" stories of ten queer adults. Engaging Butler's heterosexual matrix (1990) as an analytic tool, stories are analyzed with respect to agency and positioning. Findings suggest that participants' positioning and agency were largely affected by gender identity…

The relation between self-determination and intellectual functioning is complex, as other contextual factors may also play significant roles in explaining variability in self-determination. This study used meta-analytic techniques to assess how self-determination measures vary between people with disabilities classified as having intellectual…

"Ability" is one of the most common concepts underpinning education. Generally, "ability" is central to notions of a meritocratic society. More specifically, schools are allocated the right to define, categorise and label students according to their ability. While there has been ample discussion of the role of ability in the…

Research has highlighted the importance of early literacy development. In light of this, there has been a growing concern around boys' underachievement on language and literacy assessments. Given the recent mandate for play-based learning in Ontario kindergartens, this paper examines children's literacy integration during play from a gender…

Spatial reasoning plays a vital role in choice of and success in science, technology, engineering, and mathematics (STEM) careers, yet the topic is scarce in grade school curricula. We conjecture that this absence may be due to limited knowledge of how spatial reasoning is discussed and engaged across STEM professions. This study aimed to address…

We gave participants diagrams of traffic on two roads with information about eight attributes, including the type of each vehicle, its speed, direction and the width of the road. Their task was to record and organize the data to assist city planners in its analysis. Successfully encoding the information required the creation of a case, a physical…

This article examines the extent to which young people in New Zealand share the dominant beliefs and assumptions that inform contemporary notions of war remembrance concerning the First World War. In particular, it considers how they make meaning of the ANZAC/Gallipoli narrative. Informed by two empirical studies, it questions whether young people…

A growing body of research focuses on the impact of video games and coding on learning. The research often elevates learning the technical skills associated with video games and coding or the importance of problem solving and computational thinking, which are, of course, necessary and relevant. However, the literature less often explores how young…

Translational research (TR) is the process of bringing innovations from basic science into applied science, usually referring to the practice of medicine. It has been assumed that cross-disciplinary collaboration, or interdisciplinarity research (IDR), is essential to translation. Yet there is a gap in the literature regarding the interaction…

Two of the most significant changes in higher education over the last decade have been the reconceptualization of faculty scholarship and the increase in the hiring of adjunct faculty, yet these topics rarely merge together in the literature. The purpose of this qualitative narrative inquiry was to understand how adjunct English faculty conceive…

The following study examined the perceived developmental influence of the university supervisor-student teacher relationship during the student teaching phase of teacher preparation. Since the supervisor is viewed as the gatekeeper to eventual teacher certification and acts as an evaluator, mentor, and instructor (Borko & Mayfield, 1995;…

Prior to instruction, students often possess a common-sense view of motion, which is inconsistent with Newtonian physics. Effective physics lessons therefore involve conceptual change. To provide a theoretical explanation for concepts and how they change, the triangulation model brings together key attributes of prototypes, exemplars, theories,…

Modeling student knowledge while students are acquiring new concepts is a crucial stepping stone towards providing personalized automated feedback at scale. We believe that rich information about a student's learning is captured within her responses to open-ended problems with unbounded solution spaces, such as programming exercises. In addition,…
