Chemical reactions far from equilibrium can exhibit oscillatory behavior. Full understanding of this phenomenon is outside of the school curriculum. However, the importance of such processes in life sciences and peculiar spatial and temporal patterns accompanying the reactions can attract the attention of IB Diploma science students. They will…

In the United States, people with more education vote more. But, we know little about why education increases political participation or whether higher-quality education increases civic participation. We study applicants to Boston charter schools, using school lotteries to estimate charter attendance impacts for academic and voting outcomes.…

This research evaluates the psychometric properties of short-answer response items under a variety of grading rules in the context of a mobile learning platform in Africa. This work has three main findings. First, we introduce the concept of a differential device function (DDF), a type of differential item function that stems from the device a…

Due to its flexibility, the multiple-indicator, multiple-causes (MIMIC) model has become an increasingly popular method for the detection of differential item functioning (DIF). In this article, we propose the mediated MIMIC model method to uncover the underlying mechanism of DIF. This method extends the usual MIMIC model by including one variable…

Autism spectrum disorder (ASD) is associated with deficient comprehension of figurative language and, specifically, idioms. Theories ascribe this to deficits in specific abilities (e.g., Theory of Mind [ToM]; executive functions [EF]; general language skills), but no comprehensive theory has resulted. This study investigated the differential…

Quadcopters (also known as "drones") do not fly in vacuum. This is obvious enough that experimenting on one in a vacuum chamber would seem rather uninteresting, but there is one question that may be usefully addressed by such an experiment: the mechanism for yaw control. Quadcopters control yaw (rotation about the vertical axis) by…

This paper reviews and analyzes a 1997-98 budget proposal by the Chancellor and Board of Governors of the California Community Colleges. The proposal, entitled "Partnership for Excellence," proposes to fund a portion of the California Community College budget on a performance basis, with a differential payout mechanism for colleges based…

A general framework for assessing differential functioning of items and tests (DFIT) that was recently proposed is expanded to include differential bundle functioning as a mechanism for identifying sources of differential functioning. The expansion is illustrated with a dataset of 4000 fourth-grade students from a reading comprehension…

In contexts of first language (L1) acquisition, prediction and adaptation are often viewed as fundamental to the learning process (Rabagliati et al., 2016). One mechanism that has been proposed to specifically account for such adaptive behavior is error-based implicit learning (e.g., Chang et al., 2006). According to this account, speakers…

edTPA is designed to strengthen teacher professionalization and provide a framework for program redesign. However, using a national assessment to shift the content of local programs is challenging because of their inherent organizational complexity. In this article, we focus on this complexity, using a systems lens to analyze edTPA implementation…

This research examined how 5-, 8-, and 11-month-olds with female primary caregivers mentally represented faces using a familiarization procedure similar to real-world experience in which infants have greater exposure to female faces aged 21-39 years than other face types. We predicted infants would form weighted representations of faces (i.e.,…

Prior evidence suggests that subjective well-being (SWB) remains relatively stable across adulthood. However, longitudinal evidence is sparse except in Western societies such as North America and Western Europe. We examined age-related changes in SWB (life satisfaction, positive affect, and negative affect) among middle-aged and older Japanese. We…

Globalisation has become increasingly important in education, and national systems are no longer defined only by the nation-state. The role of intergovernmental organisations such as the OECD has also become increasingly important, particularly through the development of the PISA tests and the publication of international comparison tables. With a…

The purpose of this study was to explore the psychological mechanisms of how perceived autonomy support by the principal affects positive and negative aspects of teachers' well-being. While satisfaction of the basic psychological needs (Deci and Ryan in Psychol Inquiry 11:227-268, 2000, https://doi.org/10.1207/S15327965PLI1104_01; Ryan and Deci in…

Students' social belonging in a general chemistry course has been shown to predict academic performance in that course. Additionally, students' social belonging at the beginning of a general chemistry course has been shown to differ across demographics, such as gender. This social belonging exists as both an absolute sense of belonging in the…
