According to literature, the classic "paideia" ideal, that is, the ideal of the well-rounded, fully educated, rational human being, has survived to this day, despite many historical and socio-cultural influences that impacted on it through the millennia. In the process, it has to a considerable extent retained its rationalistic bias, but…

The purpose of this article is to present a content map and sequenced learning tasks to teach tennis footwork techniques in a physical education setting.

Creating pleasant musical sounds by vibrating the strings of musical instruments such as guitars and violins is the result of the type of instrument played as well as the mastery of the player. This article explains the physics of vibrating strings caused either by a bow drawn over them or by being plucked, and provides a simple analysis to…

The goal of teaching children to read is not for them to learn a set of discrete decoding skills, it is to have the reader obtain meaning from the words on the printed page, to understand the message which the writer tried to convey when he wrote down the words. The goal is comprehension of the printed word. While children are taught multiple…

This article highlights some of the challenges in explaining simple substituent effects on keto-enol equilibria, particularly to an undergraduate audience. Quantum-chemical calculations were performed to identify the role of intramolecular hydrogen bonding, inductive effects due to electron-withdrawing groups, and cross-conjugation on the…

Basis vectors e[subscript alpha] play a useful role in special and general relativity. In particular they allow an expansion of the vectorial spacetime interval dl along infinitesimal curvilinear coordinate differences dl = e[subscript alpha]d[Xi][superscript alpha]: (thus the definition e[subscript alpha] = dl/d[Xi][superscript alpha]). In this…

As the size of a nanoparticle is reduced, the fraction of surface atoms increases. It is interesting to note that various chemical and physical properties depend on the fraction of surface atoms. One of the most obvious questions that arise is how could one possibly estimate the fraction of surface atoms in a nanoparticle? Herein, we discuss…

The present technology report is aimed at demonstrating how the implementation of VR chemistry simulations of atomic structure enhances learning among students. MEL Chemistry VR lessons were incorporated into the classroom for 43 first-year undergraduate ITMO University students. The visualization techniques provided the learners with two…

Providing examples suitable for the children's world in the music education given to younger age groups may reinforce the knowledge to be taught. For this reason, cartoons can be utilized for an engaging and fun lesson environment. One of the best examples of this situation is believed to be the short cartoon series Silly Symphony produced by Walt…

The paper presents analyses of multivariable calculus learning-teaching phenomena through the lenses of DNR-based instruction, focusing on several foundational calculus concepts, including "cross product," "linearization," "total derivative," "Chain Rule," and "implicit differentiation." The…

Several new approaches to calculus in the U.S. have been studied recently that are grounded in infinitesimals or differentials rather than limits. These approaches seek to restore to differential notation the direct referential power it had during the first century after calculus was developed. In these approaches, a differential equation like dy…

The data sets used in statistics education have changed over time, from mathematically "well-behaved" ones that facilitated computation, to more context-rich sources and now, with the increasing influence of data science practices, to "found" data, often from open data sites. As data sources change, it is important for…

Research in teacher education is still a field dealing with open questions. One of these open fields is the incorporation of new pedagogical principles such as inquiry-based processes. In this transition encouraged by most national curricula, knowledge involved in study processes changes heavily: it moves from well-established and static knowledge…

The rapid growth of inexpensive and easily accessible communicating devices embedded into new or existing physical devices transform them into the intelligent devices that comprise the Internet of Things (IoT). The increasing use of these devices has attracted attention from various sectors, including consumer market, business, industry, health,…

Literacy journals provide an important resource for teachers' professional development. Although school districts offer in-service education for their faculty and teachers often attend conferences and workshops sponsored by professional teaching organizations, journal reading remains an important source of information for teachers' ongoing…
