This study assesses the impact of cognitive and noncognitive pre-characteristics on college graduation in Tennessee. The State of Tennessee has applied multiple campus-based interventions at the Tennessee Board of Regents and the University System of Tennessee to increase graduation rates. This study is driven by three concepts and investigated by…

This study quantitatively and qualitatively measured gender and age differences in cognitive, affective, and behavioral engagement while playing video games among the University of North Texas (UNT) undergraduate students. Also, it examined the relationship between time spent playing video games and the three engagement states. For the…

This dissertation reports on three studies about students' conceptions and learning of the idea of instantaneous rate of change. The first study investigated 25 students' conceptions of the idea of instantaneous rate of change. The second study proposes a hypothetical learning trajectory, based on the literature and results from the first study,…

News sharing has become a common user behavior in social networking services (SNS) and has been extensively studied as an emerging community practice. This dissertation presents four studies extending current news sharing knowledge. It also provides promising new directions for future investigation. Study 1: suggests that news sharing is a complex…

The ability to efficiently compare number symbols, such as digits, is associated with mathematics competence across the lifespan. Performance on symbolic number comparison tasks differ across age groups; young students who are developing fluency with digits improve on symbolic number comparison, and performance is better in adults than children.…

This conceptual paper discusses two frameworks, developed independently by the lead author, that will provide the conceptual foundation for the identification and evaluation of mental computation strategies students demonstrate during an upcoming research project entitled Mental Computation in Year 5. These frameworks will be used by the lead…

In this article, we explore the uniqueness of argumentation within the field of history, considering whether historians' processes in crafting an interpretive argument from inexact evidence might provide insights into processes vital for informed civic engagement and civil dialogue in democratic societies. We discuss the role of argumentation in…

Professional development (PD) courses are the main context for mathematics teachers' lifelong learning. Leaders with expertise are needed to facilitate these courses; thus, there is a growing interest in understanding the nature of this profession, its core practices, and the challenges it entails. This paper focuses on a specific group of…

Gamification is typically implemented digitally. However, digital gamification is not always possible because of limited resources and logistical problems. It is thus necessary to explore low-threshold gamification methods that can be easily adopted in classrooms. One such method is non-digital gamification using physical game design elements.…

Background: Physical activity (PA) is considered an important factor affecting academic achievement (AA). Different intensities of PA affect mental engagement (ME), which, in turn, affects AA. However, the role of ME in the relationship between PA and AA remains unclear. Objective: This study aimed to examine the mediating and/or moderating role…

Acting upon target stimuli from the environment becomes faster when the targets are preceded by a warning (alerting) cue. Accordingly, alerting is often used to support action in safety-critical contexts (e.g., honking to alert others of a traffic situation). Crucially, however, the benefits of alerting for action have been established using…

Purpose: As online course enrollments increase, it is important to understand how common course features influence students' behaviors and performance. Asynchronous online courses often include a discussion forum to promote community through interaction between students and instructors. Students interact both socially and cognitively; instructors'…

Background: Digital Information Literacy (DIL) refers to the ability to obtain, understand, evaluate, and use information in digital contexts. To accurately capture various dimensions of DIL, assessment designers have increasingly looked toward complex, interactive simulation-based environments that afford more authentic learner performances.…

Natural environments provide a rich spatiotemporal context that allows for visual objects to be differentiated based on different types of information: their absolute or relative spatial or temporal coordinates, or their ordinal positions in a spatial or temporal sequence. Here, we investigated which spatial and temporal properties are…

The purpose of this study was to explore the manner in which Australian National Rugby League (NRL) referees developed their craft. Craftmanship represents an enduring, basic human impulse, related to the desire to do a job well for its own sake (Sennett, R. (2008). Prologue: Man as his own maker. In R. Sennett (Ed.), "The craftsman"…
