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…

Background and Aim: Spaced restudy has been typically tested with written learning materials, but restudy with visual representations in actual classrooms is under-researched. We compared the effects of two spaced restudy interventions: A Diagram-Based Restudy (DBR) warm-up condition and a business-as-usual Text-Based Restudy (TBR) warm-up…

There is growing evidence that targeted instruction can improve diagram comprehension, yet one of the skills identified in the diagram comprehension literature--coordinating multiple representations--has rarely been directly taught to students and tested as a classroom intervention. We created a Coordinating Multiple Representation (CMR)…

The Common Core State Standards for Mathematics (CCSSM) (CCSSI 2010) identifies the strategic use of appropriate tools as one of the mathematical practices and emphasizes the use of pictures and diagrams as reasoning tools. Starting with the early elementary grades, CCSSM discusses students' solving of problems "by drawing." In later…

In our study, we aimed to compare the impact of simulations, sequences of printed simulation frames and conventional static diagrams on the understanding of students with regard to the one-dimensional kinematics. Our student sample consisted of three classes of middle years students (N = 63; mostly 15 year-olds). These three classes served as…

The movement towards "openness" in education has tended to position itself as inherently democratising, radical, egalitarian and critical of powerful gatekeepers to learning. While "openness" is often positioned as a critique, I will argue that its mainstream discourses--while appearing to oppose large-scale operations of…

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,…
