We describe an example of learning with multiple representations in an A-level revision lesson on mechanics. The context of the problem involved the motion of a ball thrown vertically upwards in air and studying how the associated physical quantities changed during its flight. Different groups of students were assigned to look at the ball's motion…

Based on detecting long-wavelength infrared (IR) radiation emitted by the subject, IR imaging shows temperature distribution instantaneously and heat flow dynamically. As a picture is worth a thousand words, an IR camera has great potential in teaching heat transfer, which is otherwise invisible. The idea of using IR imaging in teaching was first…

The pictorial proof of the sum of [superscript n][subscript k=1] k[superscript 2] = 1/6n(n+1)(2n+1) is represented in the form of an integral. The integral representations are also applicable to the sum of [superscript n][subscript k-1] k[superscript m] (m greater than or equal to 3). These representations reveal that the sum of [superscript…

An overview and simple example of photoelectron imaging is presented, highlighting its efficacy as a pedagogical tool for visualizing quantum phenomena. Specifically, photoelectron imaging of H[superscript -] (the simplest negative ion) is used to demonstrate several quantum mechanical principles. This example could be incorporated into an…

In the late 1920s, Kiowa photographer Horace Poolaw began documenting daily life in southwestern Oklahoma with the camera. As Poolaw began making dramatically posed, narrative-rich portraits of family members, historian Lewis Mumford asserted that the modern individual now viewed him or herself "as a public character, "being…

Many Indians in the late nineteenth and early twentieth century commodified aspects of their cultures in order to make a living and sometimes present their identities, history, and artworks in ways that were satisfying to them. Ten vintage postcards from the Oklahoma Historical Society by Kiowa photographer Horace Poolaw (1906-1984) indicate that…

At work and in our personal life we often need to remember to perform intended actions at some point in the future, referred to as Prospective Memory. Individuals sometimes forget to perform intentions in safety-critical work contexts. Holding intentions can also interfere with ongoing tasks. We applied theories and methods from the experimental…

This article makes use of a case study involving two career professionals to show how visual metaphors can be used as an important part of a constructivist approach to career counseling. It discusses how visual metaphors can serve as an effective methodology for encouraging adults to engage in the self-review of career transitions, discusses…

This investigation used an experimental design to examine how a visual imagery intervention and two levels of challenge would affect the flow experiences and performance of cadets engaged in Army ROTC marksmanship training. I employed MANCOVA analyses, with gender and prior marksmanship training experience as covariates, to assess cadets' (n =…

This guide is intended for all teachers who wish to enhance their curriculum by incorporating objects and photographs into their lesson plans. Kindergarten and elementary, middle, and high school classrooms can all benefit from expanded use of these materials. The guide can be used across a range of subject areas including history, community,…

Emotion plays an ever-present role in human existence, impacting nearly every behavior and decision in some way. Research in the behavioral sciences is rife with exploration of emotion and the role it plays in everything from business decision making to health-related behavior. However, affect, the feeling or experience of emotion, is complex and…

The focus of this article is to consider visual portrayals and representations of disability. The images selected for analysis came from online university prospectuses as well as a governmental guidance framework on the tuition of dyslexic students. Greater understanding, human rights and cultural change have been characteristic of much UK…

The nature of energy is not typically an explicit topic of physics instruction. Nonetheless, verbal and graphical representations of energy articulate models in which energy is conceptualized as a quasimaterial substance, a stimulus, or a vertical location. We argue that a substance ontology for energy is particularly productive in developing…

The process of learning new surgical technical skills is vital to the career of a surgeon. The acquisition of these new skills is influenced greatly by visual-spatial ability (VSA) and may be difficult for some learners to rapidly assimilate. In many cases, the role of VSA on the acquisition of a novel technical skill has been explored; however,…

This article presents an eye-tracking study using a novel combination of visual saliency maps and "area-of-interest" analyses to explore online feature extraction during category learning in infants. Category learning in 12-month-olds (N = 22) involved a transition from looking at high-saliency image regions to looking at more…
