It began in 1869, and today we have 118 elements listed in the Periodic table, thanks to Mendeleev's work. Carbon, hydrogen, oxygen, and nitrogen are elements presented in many organic compounds. Some of them can exhibit photophysical and photochemical properties. Herein, we proposed an easy to make an experiment in chemistry classes to connect…

Purpose: High-speed videoendoscopy (HSV) is an emerging, but barely used, endoscopy technique in the clinic to assess and diagnose voice disorders because of the lack of dedicated software to analyze the data. HSV allows to quantify the vocal fold oscillations by segmenting the glottal area. This challenging task has been tackled by various…

This study examines whether the Internet of Toys (IoToys) (de)limits children's make-believe play and whether the functionality and manipulatives offered by the IoToys serve as motivational pleasure (tactile, virtual and visual) for children to engage in make-believe play. Combining Piagetian and Vygotskian ideas of play as a unity of cognition…

In meta-analysis based on continuous outcome, estimated means and corresponding standard deviations from the selected studies are key inputs to obtain a pooled estimate of the mean and its confidence interval. We often encounter the situation that these quantities are not directly reported in the literatures. Instead, other summary statistics are…

As intriguing optical phenomena that occur in nature, mirages are widely known and often mentioned in physics classes when introducing the basics of optics. In the atmosphere, a mirage occurs under the condition of vertical variations in air density, which are usually caused by a temperature gradient. The light rays are continuously refracted and…

The possibility of online Aristotelian virtue friendships via social network sites continues to be raised by philosophers, but as yet this has not been positioned within the realm of children or adolescents, who are known to be amongst the largest users of social media. Governmental agencies across the globe still struggle to define the boundaries…

This paper aims at answering the "how" questions about organizing and hosting an online conference during the COVID-19 pandemic. The 3rd International Pan-Pacific Technology-Enhanced Language Learning (PPTELL) Conference and Critical Thinking Meeting (hereafter PPTELL 2020) hosted from June 29 to July 1, 2020, on Zoom is the example…

Flipped Classroom as a pedagogical framework has gained popularity at secondary and tertiary levels of mathematics education, but there is a lack of research based on a solid theoretical foundation. This article considers the flipped mathematics classroom from the perspective of affordances and cultural-historical activity theory. The empirical…

Leading architectural firms in professional practice are expanding their range of design possibilities using digital design strategies. A digital design strategy enables architects to make informed decisions and better handle the interdisciplinary nature of the discipline, while dealing with various complexities, uncertainties and an infinite…

In this study, the self-efficacy of conservatory students was determined in piano lessons. The piano lesson self-efficacy scale developed by Kurtuldu (2017) was used. The scale was applied to 55 students studying at the Musicology and Music Theory departments at Trabzon University State Conservatory in the academic year of 2020-2021. The result of…

The current challenge of maintaining accessible, effective museum education amid an unprecedented global health crisis has proven that the necessity of public education and museum relevancy is more critical than ever. Rachel Zollinger's former employer, Explora Science Center & Children's Museum (Explora), demonstrates daily how a commitment…

This paper walks the reader through a simple mathematical characterization of the popular children's game, "Chutes and Ladders," focusing primarily on Monte Carlo simulation. The focus is then shifted to the board game "No Te Enojes" in order to analyze the implications of the introduction of strategy. The presence of strategy…

Visual programming environments are popular instruments in teaching Computational Thinking (CT) in schools today. Applying Sense-Reason-Act (SRA) programming can influence the development of computational thinking when forcing pupils to anticipate the unforeseen in their computer programs. SRA-programming originates from the programming of…

To be able to solve complex information problems in a digital environment is a key 21st century skill. Technology users usually expect to achieve their goals in a fast and accurate way. However, the actual relationship between time-on-task and task outcome is currently not well understood. We analyzed data from a large-scale international study in…

The library website is a tool shared by all library users. It is imperative to keep this tool accessible, but accessibility guidelines are not consistently applied to all library-owned pages. As institutions that receive federal funding, libraries have a responsibility to provide accessible websites. This study examines the library websites of the…
