Here, we present a strong test of the hypothesis that sacrificial moral dilemmas are solved using the same value-based decision mechanism that operates on decisions concerning economic goods. To test this hypothesis, we developed Psychological Value Theory. Psychological Value Theory is an expansion and generalization of Cohen and Ahn's (2016)…

Generalization is a critical component of mathematical reasoning, with researchers recommending that it be central to education at all grade levels. However, research on students' generalizing reveals pervasive difficulties in creating and expressing general statements, which underscores the need to better understand the processes that can support…

We examined high school geometry students' written work on four proof tasks where they posed a conjecture, drafted an argument, provided written critiques, then revised their argument based on peer feedback. Students' written work across the tasks was analyzed to determine whether the instructional sequence supported them in improving their…

Having an agreed-upon definition of character education would be useful for both researchers and practitioners in the field. However, even experts in character education disagree on how they would define it. We attempted to achieve greater conceptual clarity on this issue through a prototype analysis in which the features perceived as most central…

Algebraic thinking and strategy flexibility are essential to advanced mathematical thinking. Early algebra instruction uses 'missing-operand' problems (e.g., x - 7 = 2) solvable via two typical strategies: (1) direct retrieval of arithmetic facts (e.g., 9 - 7 = 2) and (2) performance of the inverse operation (e.g., 2 + 7 = 9). The current study…

This research was triggered by the identified need in literature for large-scale studies about the kinds of designs that teachers create for mobile learning (m-learning). These studies require analyses of large datasets of learning designs. The common approach followed by researchers when analyzing designs has been to manually classify them…

Problems of developing subject education and science have become more acute during different social changes. The most problematic is the teaching of exact disciplines, including mathematical disciplines (mathematics, algebra, geometry), which form knowledge for working in high-tech industries. It is worth noting that the methodology of teaching…

Little is explored regarding the modality-specific differences in recall abilities of preschool children. Understanding modality-specific differences in the recall at an early age might give an insight into age-linked trends, which can lay a foundation for later development. The current study used a cross-sectional design to investigate the…

The present dissertation explores the effect of exposure to non-native speech via foreign film on non-native speech production and perception. In order to explore potential effects, two main experiments were developed, which examined French production and perception by monolingual native speakers of English before and after exposure to French…

The present study explored perceptual and articulatory techniques addressing the pronunciation of Spanish rhotics by means of a week-long computerized training. Through a quasi-experimental design approach, the study tested the utility of the online training and its effects on the phonetic production of taps [voiced alveolar tap or flap] and…

Where do novel ideas come from? What mental processes facilitate them? The disinhibition hypothesis suggests creative cognition can be assisted by reducing cognitive inhibition of ideas, facilitating looser associative thoughts to bond with one another to produce novel concepts. Past exploration of the disinhibition hypothesis has been drawn from…

Though it is well-accepted that Task-Technology Fit theory is a useful framework for examining university student success in online courses, the effectiveness of the theory has rarely been studied with graduate-level students or with a sample representing more than a few universities or programs. The current study investigated learners' perceived…

In this article, we use eye-tracking technology to analyze the eye movement differences in cognitive maps between high and low level map-based spatial ability participants, revealing key factors of superior spatial ability. It is found that focusing on the perception of spatial structure information, constructing and manipulating complex images…

Short term memory (STM) and working memory (WM) performance consistently predict language abilities in children with developmental language disorders. However, causality is not fully established. Moreover, evidence from the fine-grained analysis of STM/WM tasks and comprehension of complex sentences, suggests that long term memory (LTM)…

This study investigates the possibility that solitary dialog, in which individuals construct in writing a hypothetical dialogic argument, may more fully reveal individual skill achievement in argument than do conventional argumentive essays. A sample of 54 11-12-year-old Chinese students individually composed such written dialogs, subsequent to…
