In the last years special "ovals" appear increasingly often in diagrams and applets for discussing crucial items of statistical inference (when dealing with confidence intervals for an unknown probability p; approximation of the binomial distribution by the normal distribution; especially in German literature, see e.g. [Meyer,…

The Nolan Index (NI) is a normed, quantitative measure for comparing the degree of resemblance (similarity or dissimilarity) between free listings with an Excel program for calculating it. This article enhances that effort with the addition of an R program and additional applications. Free-list resemblance measures have been used to investigate…

The study of coordination complexes in general and inorganic chemistry courses is facilitated by theoretical frameworks such as crystal field theory (CFT) and ligand field theory (LFT). The angular overlap model (AOM) is alternative approach that quantifies metal-ligand interactions based on the geometric configuration of a given complex. In this…

This design case details a seven-year iterative design process to create an app for use in online physical education classes. Each iteration addresses the shortcomings of the previous version. The most recent iteration of the app allows students to use Fitbit™ devices to record heart rate data, which each student sees as progress toward course…

Just as there's no one-size-fits-all way to educate students, perhaps there is no one-size-fits-all-way to get them to school either. That is the argument behind HopSkipDrive, a startup that is seeking to complement and redefine the traditional bus model of taking students to school. Instead of kids making their way to the pre-determined route of…

The challenges faced by transition-age youth (TAY) with level one autism spectrum disorder (L1-ASD) during the transition to adulthood can be exacerbated by disability-related hurdles, particularly in employment and post-secondary education. Existing social skills training interventions for TAY with ASD often include building social narratives and…

Cost-effective and user-friendly, mobile phone-assisted methods have remained underutilized in qualitative social science research. The scarce methodological guidance, together with recruitment and ethical challenges, has arguably stifled advancements in this area. COVID-19 exposed the need to better equip researchers with the expertise and tools…

The subject of mathematics is important for many other subjects, including physics. The questions we ask in physics often need a mathematical translation to be graphically interpreted and transformed. Students learn physics when interacting with physical questions; questions from physics also give insights and discoveries in mathematical problems.…

Social gaming--online gameplay involving digital interactions with others--is a common form of social media use among adolescents. Research on this topic has neglected the social aspect of gaming and the potential role of social gaming in adolescent development. In this article, we define social gaming, drawing on interdisciplinary theories to…

This paper shares a rhizomatic unfolding of how a creative, post-qualitative praxis for becoming adventurous in the field of Relationships and Sexuality Education (RSE) can unfold in a conducive policy and practice context (Wales, UK). Specifically, we focus on the making and mattering of what we call 'Crush-Cards'. These are a suite of…

The complexity of the art of teaching and learning, especially in the field of mathematics, calls for a broader approach than the traditional status quote. Proof without words in geometry coupled with the dynamic and interactive GeoGebra applet have the capacity to be used in all levels of mathematics education from grade schools to higher…

Over the last decade, smartphones have become commonplace. Today, 95 percent of American teenagers have a supercomputer in their pocket. Jonathan Haidt, Jean Twenge, and others have brought necessary attention to the likelihood that smartphones and social media are partly to blame for the teenage mental health epidemic gripping the nation. It's…

This article discusses iBiome-Wetland, the first educational game from the author's company Springbay Studio. It invites children to build virtual wetland ecosystems, learn about 54 species living in wetlands, experience biodiversity, and conduct experiments to find out how food webs work. The game has received five awards from prestigious…

The underrepresentation and underperformance of low-income, first-generation, gender minoritized, Black, Latine, and Indigenous students in Science, Technology, Engineering, and Mathematics (STEM) occurs for a variety of reasons, including, that students in these groups experience opportunity gaps in STEM classes. A critical approach to disrupting…

Most children and young people now live a significant proportion of their lives online, a situation that has been accelerated by the COVID-19 pandemic which required many services, including education, to go online. Social media apps, messaging apps, online gaming, and chatrooms provide new and important spaces for children and young people to…
