A remarkable amount of perceptual development occurs in the first year after birth. In this article, we spotlight the case of color perception. We outline how within just 6 months, infants go from very limited detection of color as newborns to a more sophisticated perception of color that enables them to make sense of objects and the world around…

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…

Working with cognitive literary theory, affect theory, semiotics, and recent picturebook scholarship, this essay looks at the ways the concept book (as a subtype of the picturebook format) connects color to emotion. In doing so, it suggests that one of Western culture's most commonly accepted ideas of color and color meaning may contribute to…

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,…

This paper explores how students connect meaningfully with theory through the aesthetic experiences of problem solving together in the context of a workshop. It can be challenging for students studying design in university programs to understand how theory is relevant, when applied in practical design studio activities. In the colour workshop…

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…

We present herein a module of pigment synthesis experiments that could be adapted and implemented in a variety of curricular settings. At the conclusion of each of the past two spring terms at our high school, we offered a 4 day short course on the chemical synthesis of pigments used in art. As part of the course, our students synthesized four…

This paper presents the development and structure of indigenous Nahua teachers' ideas about mixing colors, as well their ideas about colors derived from their traditions. For the scientific school knowledge, teachers answered two questionnaires and an interview regarding knowledge from their culture; they were interviewed outside school. This…

In this article, we assess an alternative account of a key experimental pattern thought to index top-down control. The list-wide proportion congruence effect is the well-documented pattern whereby the congruency effect (i.e., Stroop effect) is attenuated in lists containing mostly incongruent trials relative to lists containing mostly congruent…

Through a close reading of five nineteenth-century instructional books in the Osborne Collection of Early Children's Books, this essay examines the relationship between new print technologies, memory, teaching, and learning. The article beings with a discussion of Comenius's seventeenth-century "Orbis Pictus," considered the first…

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.

Every substance is associated to emission of electromagnetic radiation whose peaks are essentially influenced by temperature. Hot bodies (i.e., at T >700 °C) emit electromagnetic radiation in the field of visible light (incandescent light). The radiation emitted by cold bodies (i.e., at normal ambient conditions) in the visible light range is…

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…

This article uses reflective drawing to explore representations of multilingualism by Anglophone migrants in Luxembourg. Analysing twelve interviews in which participants drew and described their language experiences, we examine the language ideologies Anglophone migrants adopt in response to the ideologies of English they encounter. Participants…

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…
