An experimental design by combining hydrogel and ethylenediaminetetraacetic acid disodium salt (EDTA) for visually displaying chemical complexation reactions is developed. The Na[superscript +] ions on the [alpha]-l-guluronic acid (G) unit of the sodium alginate molecule undergo an ion exchange with a divalent cation, so that the G units are…

A quantitative titration of the amount of magnesium hydroxide in milk of magnesia using only items purchased in grocery and retail stores is reported. Either vinegar or a solution of food grade citric acid serves as the titrant, while food dyes advertised as being extracted from natural sources provide the end-point indicator. An inexpensive,…

The topic of recurrence relations has recently been introduced in many discrete mathematics textbooks. Recurrence relations are efficient modelling and problem-solving techniques used in mathematics. Combinatorial problems are often used to introduce recurrence relations. However, many textbooks consider problems that can be reduced only to the…

This article posits that the comic medium, wedded with traditional essay assignments, may be a powerful tool for social studies teachers, those who prepare social studies teachers at the collegiate level and other teachers and professors who desire to teach about citizenship in an era of "fake news" and alternative facts.

In this paper, I aim to explore what role persuasion plays in the early education of children. Advocating Wittgenstein, I claim that persuasion involves imparting to a pupil about a particular world-picture ("Weltbild") by showing rather than explaining. This because we cannot introduce a child to the hinges of a world-picture through a…

When people perceive the world, what they see is based on the physics of light reflecting off surfaces and entering their eyes. Their brain then processes the raw data so that photoreceptor activity becomes perceptual awareness. Most textbooks and chapters on sensation and perception follow this formula, building student understanding of…

In a society that strives for sustainability it is important to observe and value different forms of knowledge. Creating art is not a meaningless exercise. Instead, one might say that works of art serve as a window that interprets the world. In the article it is argued that artistic actions can offer a combination of critical and creative thinking…

This article is co-written by a student and professor about their reflections of art education course they participated in. The authors use three font colors in this article to chronicle certain memories related to the course content from the perspective of student (orange) and professor (teal). They also use black text to exemplify the blurred…

This article looks to three inspirational Black women, bell hooks, Stacey McBride-Irby and Patricia Williams, in the pursuit of radical curriculum. While today curriculum is critiqued as racialised, gendered, sexualised and classed, the formats of curriculum documents such as text books, units of work and lesson plans have changed little. These…

In this article, the authors focus on children's and adults' analyses and interpretations of the artwork and design of Peter Brown's "Mr. Tiger Goes Wild." Sipe (2008b) noted how the body of research on "children's visual meaning making from picturebooks" would benefit from "more studies combining careful and theoretically…

This article seeks to provide some modest insights into the pedagogy of higher-order thinking and metacognition and to share the use of color-coded drafts as a best practice in service of both higher-order thinking and metacognition. This article will begin with a brief theoretical exploration of thinking and of thinking about thinking--the latter…

This article examines several readily available "magic tricks" which base their "trickery" on physics principles, and questions the use of the word "magic" in the 21st century, both in popular children's science and in everyday language. (Contains 18 figures.)

This study investigates teaching methods regarding color comprehension and color categorization among blind students, as compared to their non-blind peers and whether they understand and represent the same color comprehension and color categories. Then after digit codes for color comprehension teaching and assistive technology for the blind had…

In recent years, the government in Singapore has invested a large amount of time and money in the fast-moving industry of digital media. Some schools have begun to increase their commitments and make the necessary readjustments to integrate digital content into the learning process. The outcome of these changes has indirectly affected the…

Notes that suggestions have been made in the media that tinted lenses may provide a "cure" for developmental dyslexia, and considers how there have been many anecdotal accounts of improvements in reading following their use. Provides an overview of the research into the use of tinted lenses for the amelioration of reading difficulties. (SG)
