Most future teachers are familiar with number patterns that represent an arithmetic sequence, and most are able to determine the general representation of the "n"th number in the pattern. However, when they are given a visual representation instead of the numbers in the pattern, it is not always easy for them to make the connection between the…

Many people, whether old or young, male or female, typically developing or living with a disability, become quite anxious at the idea of a needle. They anticipate the possibility of pain, however brief, and try to avoid the experience. The reality is that any discomfort is usually very brief, and the entire process only takes a minute or two from…

In this article, the author begins with a proposition asking what if visual thinking were privileged in the English classroom and then proceeds to elaborate on a curriculum grounded on three principles: (1) sense and perception as starting points; (2) meta-conceptual links between visual and verbal texts; and (3) the art of visualization in…

Attentional interference between tasks performed in parallel is known to have strong and often undesired effects. As yet, however, the mechanisms by which interference operates remain elusive. A better knowledge of these processes may facilitate our understanding of the effects of attention on human performance and the debilitating consequences…

The effect of density inversion on the convective flow of water in a spherical glass flask cooled with the help of an ice-water bath is shown. The experiment was carried out by temperature measurements (cooling curves) taken at three different heights along the vertical diameter of the flask. Flows inside the flask are visualized by seeding the…

A visual method for counting significant digits is presented. This easy-to-learn (and easy-to-teach) method, designated the box-and-dot method, uses the device of "boxing" significant figures based on two simple rules, then counting the number of digits in the boxes. (Contains 4 notes.)

One may have heard of Bowland maths and will know something of the "case studies" that were published in 2008. These are substantial mathematics projects, taking five hours, or more, to complete. Most are set in real or realistic contexts, like "designing a smoothy"--Product Wars, or "devising plans to improve road safety"--Reducing Road…

Visually based interventions such as video modeling have been demonstrated to be effective with students with autism spectrum disorder (ASD). This approach has wide utility, is appropriate for use with students of a range of ages and abilities, promotes independent functioning, and can be used to address numerous learner objectives, including…

The methodology in this paper discusses the use of photographs as an elicitation strategy that can reveal the thinking processes of participants in a qualitatively rich manner. Photo-elicitation techniques combined with a Piercian semiotic perspective offer a unique method for creating a frame of action for later participant analysis. Illustrative…

Despite a profusion of popular misinformation about the left brain and right brain, there are functional differences between the left and right cerebral hemispheres in humans. Evidence from split-brain patients, individuals with unilateral brain damage, and neuroimaging studies suggest that each hemisphere may be specialized for certain cognitive…

When teachers provide students with every opportunity to visually understand a mathematical concept, process, definition, or notation, they allow them to construct and manipulate relevant and useful images in their minds. Visual understanding has a dynamic character that they do not easily develop with alphanumeric symbols alone despite the…

The close relationship between charged particles and electromagnetic fields has been well known since the 19th century, thanks to James Clerk Maxwell's brilliant unified theory of electricity and magnetism. Today, electromagnetism is recognized as an essential aspect of human activity and has consequently become a major component of senior…

Key characteristics of autism include differences in communication, social interaction, and restricted or repetitive activities and interests (American Psychiatric Association, 2000). Because of these differences, active engagement is challenging for many young children with autism spectrum disorders (ASD). However, such engagement in a variety of…

This article describes a set of strategies for including children with autism in circle time. Successful inclusion involves careful planning, collaboration, and consideration of individual needs. Circle time can be a positive activity for children with autism when individual needs and strengths are considered. Environmental modifications and…

This paper stages a corporeal and affective trail through plateaus of "Becoming deaf" in the workplace of academia. The paper aims to display the unfamiliarity of deafness in a profession whose ability to speak and hear the written word is all too commonsense. In this piece, Deleuze and Guattari's "rhizome" acts as sensibility and motif as a body…
