Posters abound in education libraries as decorative objects yet few libraries realize the educational potential of the poster. Posters are colorful, attractive learning media which can enhance the learning environment. This paper describes the value of posters in the educational setting, offers suggestions on selecting posters for learning, and…

Three-month-olds are sensitive to orientation changes of line drawings when they have a three-dimensional (3-D) interpretation and when the changes are defined by both 3-D depth and two-dimensional (2-D) picture plane cues [Bhatt, R. S., & Bertin, E. (2001). Pictorial cues and three-dimensional information processing in early infancy. Journal of…

Videos and DVDs give the teachers more flexibility than slide projectors, filmstrips, and 16mm films but teachers and students are excited about a new technology called streaming. Streaming allows the educators to view videos on demand via the Internet, which works through the transfer of digital media like video, and voice data that is received…

For a head start on getting great reading and writing materials this summer--just look in your mailbox. As the school year winds down and the end-of-year testing and report card frenzy nears, summer looms large. If you have the good fortune to be in a school that isn't year-round, and you aren't working on college credit or at a second job, just…

In the mid-1800s, Englishman John Venn invented a type of diagram to help visualize logical relationships. A Venn diagram is simply a rectangular box with circular loops in it that overlap to show how objects are related. This article describes activities with Venn diagrams that can be a fun way to sharpen students' logic skills and develop number…

Amongst the many recent developments in learning technology, video streaming appears to offer a considerable range of benefits for tutors and learners alike. For these to be fully realised, however, various conditions have to be met. Merely making streams available and directing students to them, does not necessarily result in quality, or indeed…

The movie industry heavily relies on storyboards as an effective way to visually describe the process of a movie. The storyboard visually describes how the movie flows from beginning to end, how the characters are interacting, and where transitions and/or gaps exist in the storyline. The storyboard is an effective tool in industrial design as…

Objective: To expand an informative speech into a television news package. Type of speech: Informative. Point value: 5% of course grade (Note: The original informative speech is worth 10% of the course grade). Requirements: (a) References: 3; (b) Length: 30 seconds; (c) Visual aid: 3; (d) Outline: Yes; (e) Prerequisite reading: Chapter 14 (Whitman…

Previous work has shown that illiterate subjects are better at naming two-dimensional representations of real objects when presented as colored photos as compared to black and white drawings. This raises the question if color or textural details selectively improve object recognition and naming in illiterate compared to literate subjects. In this…

Two experiments tested the DeLoache, Pierroutsakos, Uttal, Rosengren, and Gottlieb (1998) claim that 9-month-old infants attempt to grasp objects depicted in photographs. In Experiment 1, 9-month-olds viewed an object, a photograph of the object, and 2 flat, nonpictorial displays. On average, they reached for the photograph and nonpictorial…

If vision can be considered the basis of geographic inquiry, then it must involve looking with discrimination--the ability to discern clues in our surroundings that speak to spatial processes or patterns in all aspects of geography--physical, cultural, economic, and so on. Geographic thinking also involves making spatial generalizations. We do…

A few years ago, the author was introducing her students to David Hockney's "Pearblossom Highway" photo collage, when she decided to try his technique herself. It turned into an assignment that her students love and request. Hockney states that "Pearblossom Highway" gives "a sense of closeness to everything yet at the same time depth can be…

In this paper, a new automatic contour tracking system, EdgeTrak, for the ultrasound image sequences of human tongue is presented. The images are produced by a head and transducer support system (HATS). The noise and unrelated high-contrast edges in ultrasound images make it very difficult to automatically detect the correct tongue surfaces. In…

When students take General Chemistry there are substantially fewer molecular images than they will encounter in Organic Chemistry. The molecular images Organic Chemistry students see in their textbooks are ones that use dashes and wedges to represent 2D and semi 3D views, ball and spoke, ball and wire, and structural formulas, to name just a few.…

When visualization tools utilized in computer programming education have been evaluated empirically, the results have remained controversial. To address this problem, we have developed a model of short-term effects of program animation, and used it in a series of experiments. In the current experiment, we varied visual representation of an…
