M. Singh and B. L. Anderson proposed a perceptual theory of achromatic transparency in which the perceived transmittance of a perceived transparent filter is determined by the ratio of the Michelson contrast seen in the region of transparency to that of the background seen directly. Subsequently, B. L. Anderson, M. Singh, and J. Meng proposed that…

All of the data reported in Robilotto, Khang, and Zaidi (2002) Robilotto and Zaidi (2004), and Singh and Anderson (2002) are consistent with Robilotto and Zaidi's theory that perceived transparency (or opacity) is determined by the perceived contrast of the filter region. Kasrai and Kingdom's (2001) results also appear largely consistent with the…

Two-time Caldecott Honor winner (Free Fall, Sector 7) and three-time Caldecott Medal winner (Tuesday, The Three Pigs, Flotsam), David Wiesner is regarded as one of the most remarkable creators of visual storytelling living today. Wiesner is well known for his innovative and unique subject matter and his sophisticated painting-like illustrations…

Discussion of visual literacy, visual cognition, visual thinking and learning, and visual knowledge focuses on women and gender differences. Topics addressed include educational equality and the visual, including equality versus difference; women and mass culture; difference and the design of visual instruction; and feminist education and the…

Description of ways in which computers might be used to teach visual concepts discusses hypermedia systems; describes computer-generated tutorials; explains the use of computers to create learning aids such as concept maps, feature spaces, and structural models; and gives examples of visual concept teaching in medical education. (10 references)…

Arguing that a well designed graphical display can function as a memory store, this article suggests three principles for the design and use of computer graphics: parsimony, accessibility, and reflection. It is suggested that "progressive graphics" are particularly suited to computer implementation. (Author/MBR)

Describes two hours in the life of an eight-year-old to demonstrate that children acquire information and develop language skills from multiple sources. Argues that the conceptualization of literacy must be broadened from reading and writing skills to a definition that recognizes the layering of information and that includes all forms of the…

Discusses the suitability of multimedia technology for the representation of complex visual events in the classroom and describes a program that uses videodisk and HyperCard to teach students about the factors involved in the creation of theatrical performances. Principles to guide the design of multimedia applications for the classroom are…

The ability to see whether a map is equal-area, conformal, or neither is useful for looking intelligently at large-area maps. For example, only if a map is equal-area can reliable judgments of relative size be made. If a map is equal-area, latitude-longitude cells are equal in size between a given pair of parallels, the cells between a given pair…

Discusses current changes in the structures of British art education in light of the 1988 Education Reform Act (ERA), and describes the use of microcomputers to develop visual sensitivity and skills. A test model is discussed which examines an experiential approach toward the teaching, evaluation, and interpretation of color theory. (five…

The efficacy of using graphic representations of concepts, which are more readily generated on a computer than in traditional texts, was studied. The study, which involved teaching computer programming, is described. The necessity of further research is discussed. (JL)

Discusses the use of videodiscs to increase students' comprehension. Benefits of adding visual images to learning activities are discussed, videodiscs as sources of data for students to analyze are considered, and an example is given of using videodiscs to illustrate concepts in a chemistry class. (LRW)

Discusses reasons for the failure of educational television (ETV) projects in various countries. Topics discussed include the Centre for Educational Television Overseas (CETO); the Multinational Project in Educational Technology; problems with television and video technology; management and planning; research; the role of visual learning; and…

Children starting school today have already been trained to learn by television, and the skills they have developed may not be suitable for the print-oriented learning required in school. Differences in learning from electronic sources and from books are discussed, as are strategies teachers can use to help children adjust. (PP)

Considers issues that need to be addressed when incorporating audio in courseware design. Topics discussed include functions of audio in courseware; the relationship between auditive and visual information; learner characteristics in relation to audio; events of instruction; and audio characteristics, including interactivity and speech technology.…
