Analysis of (n=92) university students' construction of visual representations (Venn diagrams) of eight set expressions found competent and error-prone students constructed and used procedures to complete set translation tasks, and two-thirds of observed errors arose from consistent implementation of ill-formed procedures. (Author/MKR)

Structures of multiple education and knowledge systems can be recreated in maps, in a social cartography where the space of the social map reflects effects of social changes in real space. Such maps allow social research to escape from modernism's positivist restraints, improve comparative educators' understanding of the social milieu, and open…

Benign visual hallucinations ("phantom vision") were examined in 2 studies, involving a total of 443 adventitiously blinded and sight-impaired veterans. In one study, unusual visual events were reported by 38.7 percent, with 30.6 percent reporting complex hallucinations. Causes of the hallucinations and their treatment are discussed.…

Discusses problems in creating indices and thesauri for digital libraries of geo-spatial multimedia content and proposes a scalable method to automatically generate visual thesauri of large collections of geo-spatial media using fuzzy, unsupervised machine-learning techniques. Uses satellite photographs as examples and discusses texture-based…

Explores the development of elementary school students' (n=88) understanding of comparing two datasets through the responses of students in individual interview settings. Strategies observed within the developmental cycles were visual, numerical, or a combination of the two. Contains 26 references. (Author/ASK)

Two psychometric tests measuring mental rotation (MR) and visualization (VZ) were administered to 209 male and 390 female high school seniors. Results clearly indicate that MR is a plausible mediator variable for sex differences in VZ when such differences do exist. Theoretical, methodological, and practical consequences of these results are…

Discusses the use of Web log analysis to help understand user visit patterns to Web sites and describes the use of computer software to generate a variety of interactive visualizations of log data that can be used to explore server data across various dimensions. Explores difficulties of data collection, presentation, and interpretation.…

Explains Visual Information Retrieval Interfaces (VIRI) and examines the effectiveness of a two-dimensional display format compared to a more standard sorted result list. The Visual Information Browsing Environment (VIBE) was modified to investigate the interaction of the verbal and spatial abilities of users, as measured by cognitive factors…

Focuses on difficulties students have in reading images and understanding a particular domain; e.g., optics and color. Concentrates on the extent to which teachers were conscious of such difficulties and what they suggested doing to avoid possible pitfalls. (Author/MM)

Introduces the use of Formal Concept Analysis (FCA) as a methodology to visualize the data in computer-mediated communication. Bases FCA on a mathematical lattice theory and offers visual maps (graphs) with conceptual hierarchies, and proposes use of FCA combined with content analysis to analyze computer-mediated communication. (Author/LRW)

Visual environment is a neglected area of study in secondary science. Investigates the structure of science classrooms, display materials used, and components of the science curriculum including information on the sex and subject specialization of staff involved with teacher trainees. (Author/YDS)

Takes the concept of using a geometrical or visual approach to teach algebraic concepts and extends it to connect with the section on binomial expansion by using three dimensional objects. (ASK)

Discusses visualization of legal information using a tool for temporal information called "LifeLines." Explores ways "LifeLines" could aid in viewing the links between original case and direct and indirect case histories. Uses the case of Apple Computer, Inc. versus Microsoft Corporation and Hewlett Packard Company to…

Today's designers deal with a range of communication modes. These modes vary from hand gestures to sketches, physical models, and computer-generated images. It has been the norm to use these mediums throughout the process to visualize the intended design so that the potential users, designers, team members, and clients can understand the end…

The authors conducted 2 experiments to study the metrics of spatial distance in a mental imagery task. In both experiments, participants first memorized the layout of a building containing 10 rooms with 24 objects. Participants then received mental imagery instructions and imagined how they walked through the building from one room to another. The…
