In this work, we venture to show how careful use of a program for quantum chemical calculations (such as VASP) may enrich teaching in solid-state chemistry and how principles of thermodynamics contribute to a validation of phase diagrams and reaction pathways using the quasiternary system Li[subscript 2]O-Al[subscript 2]O[subscript…

The goal of this note is to obtain the area enclosed between a parabola and two tangent lines using visual arguments. The first step that we have to follow, in order to do that, is noticing that the area between a parabola and a tangent line only depends on the leading coefficient of the quadratic function of the parabola. Finally, the…

This study examined the use of analogy in architectural design. Its main goal was to provide an understanding of how experts and novices alike used visual analog thinking to generate satisfactory solutions during their design process. A series of controlled experiments were conducted in order to examine how this cognitive strategy contributes to…

X-rays are such an important and familiar part of the electromagnetic spectrum, but is there a way to safely bring x-rays into your lecture? The demo team at the University of California at Berkeley seems to have managed this. They have an x-ray safe box that they use to produce a live x-ray image on a fluorescent screen. In this article, we…

We explore an innovative approach to learning design representations called course composition diagrams, which consist of interactive digital icons representing course elements, such as videos and quizzes. Course composition diagrams present a visual overview of course structure, including the placement and sequence of individual elements within a…

Research on mathematical problem solving has a long tradition: retracing its fascinating story sheds light on its intricacies and, therefore, on its needs. When we analyze this impressive literature, a critical issue emerges clearly, namely, the presence of words and expressions having many and sometimes opposite meanings. Significant examples are…

We have updated a version of the coordination geometry table of the d-block elements and their ions that Moore and co-workers presented in 1997. This table is constructed by searching and analyzing the data in the Cambridge Structural Database. In this updated version, we have also analyzed impact of ligands on the coordination geometry and…

Various strategies have been promoted to increase student engagement in collaborative activities in chemistry courses, including the use of small portable whiteboards where students can represent and share ideas. In this paper, we summarize the results of a study designed to investigate how the use of small portable whiteboards during groupwork…

Over the past few years, art educators (Cooper et al., 2018; Grodoski, 2018; Taylor, 2017) have begun to embrace data visualization for curricular purposes. In this article, the authors make a case for the inclusion of data visualizations in K-12 art curricula and illustrate a curriculum that focused on introductory data visualization concepts and…

This is the fifth in a series of statistical articles for mathematics teachers. In this article the authors discuss graphs for exploring relationships between one categorical variable and one numerical variable using stemplots and boxplots and between two numerical variables, using scatterplots and time series plots. [For "The Data Files 4:…

The COVID-19 pandemic is arguably the worst crisis the world has faced, so far, in this new century. We haven't seen a pandemic like this since the "1918 Flu" at the beginning of the last century, and, as of this writing, there appears to be no end in sight. What those of us who're focused on quantitative methods have noticed, in…

Vision and language are the primary modalities of our human perception and learning. Recent years have witnessed fast development of methods that connect vision and language. Current deep learning methods are data-hungry, thus pre-training on large-scale data helps warm up the model and shows better fine-tuning results on downstream tasks.…

Despite the acceleration of climate change, figuring out ways to productively talk about it remains difficult in some places. So where do we begin? As rhetoricians, we believe that studying discourse provides insight. Herndl and Brown describe environmental discourse as a historically developed cultural form maintained by rhetorical activity (9).…

In this study, 56 participants' (N=56) perceptions towards dual coding in design of audio-only listening texts (i.e. re-provision of the same audio-only listening texts in the form of audio-only listening texts + keywords or supplementary contextual visuals + keywords at non-initial phases of the while listening stage) in a hypermedia listening…

The aims of this study were to compare the use of Review Questions (RQs) and RQs + Response Cards (RCs) in a Spanish university context; to observe which procedure most increases Active Student Responses (ASRs), to verify whether the use of these procedures improves the accuracy of students' exam answers and, to observe whether unscheduled ASR…
