This three-piece movable-parts aid saves time in teaching the scaling of photos and illustrations in graphic arts. (Editor)

Describes the history of projectors, images, and variations of projection, and uses in still projection. (CMV)

Briefly sketches the last 20 years of research on instructional pictures emphasizing the effects of increasingly analytical approaches, changing conceptions, and changing research questions. Recent trends in picture research are discussed in three areas: pictures v pictures, pictures v words, and pictures plus words. (Author)

Introduces a rotation and scale invariant log-polar wavelet texture feature for image retrieval. The underlying feature extraction process involves a log-polar transform followed by an adaptive row shift invariant wavelet packet transform. Experimental results show that this rotation and scale invariant wavelet feature is quite effective for image…

Describes the four basic information graphics: fever, bar, pie, and map. Provides five tips for creating visuals for graphs: (1) plot the numbers first; (2) set the numbers horizontally; (3) make it accurate; (4) use artwork that fits; and (5) use appropriate type. (MS)

Responds to comments on a previous article on metaphysics and educational technology that also included a visual parable. The nature of meaning is discussed; the relationship between author, text, and reader is examined; and the binary opposition inherent in technology are considered. (LRW)

Discussion of the development of technologies to assist people with developmental disabilities to engage in constructive activity focuses on the development, evaluation, and use of VICAID, a system based on a simplified palmtop computer which enables a person to access pictorial instructions designed to help in the accurate completion of tasks.…

A visual diagram is presented in this article to illustrate 6 key concepts of Adlerian theory discussed in corresponding narrative format. It is proposed that in an age of multimedia learning, a pictorial reference can enhance the teaching and learning of Adlerian theory, representing a commitment to humanistic education. (Contains 18 references.)…

Students pay attention to videos that will help them in life and enable them to get better grades. When watching documentaries, they want relevance versus canned presentations with actors. So do you, for that matter. Because many students go home to a steady diet of television, rock videos, video games and box office movies--all of them well--made…

To the extent that all types of visual stimuli can be verbalized to some degree, verbal mediation is intrinsic in so-called ''visual'' memory processing. This impurity complicates the interpretation of visual memory performance, particularly in certain neurologically impaired populations (e.g., aphasia). The purpose of this study was to…

The terms dynamic representation and animation are often used as if they are synonymous, but in this paper we argue that there are multiple ways to represent phenomena that change over time. Time-persistent representations show a range of values over time. Time-implicit representations also show a range of values but not the specific times when…

This paper discusses an investigative approach to problems concerned with approximations. Two problems are analysed in detail and both are inspired by their historical origins. The first examines an ancient Chinese formula for calculating the area of a segment. The second looks at Durer's construction for the trisection of an angle. It is argued…
