Examines types of graphical representation as to their suitability for knowledge acquisition in primary grades. Uses the concept of mental models to clarify the relationship between external presentation and internal representation of knowledge. Finds that students who learned with highly elaborated and highly structured pictures displayed the…

This paper discusses issues of representation in the use of scientific visualizations, specifically those used for biomedical applications, and the implications of those issues to interface design. Topics addressed include the benefits of research into the generation of virtual simulation (virtual reality) and the importance of realism. (Contains…

Attempts to define how the amount of realistic detail in a visualization affects subjects' achievement. (KS)

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…

Explicit instruction in thinking skills must be a priority goal of all teachers. In this book, the author presents a framework of the five Rs: Relevancy, Richness, Relatedness, Rigor, and Recursiveness. The framework serves to illuminate instruction in critical and creative thinking skills for K-12 teachers across content areas. Each chapter…

Describes the construction of unit cells using clear plastic cubes which can be disassembled, and one inch cork balls of various colors, which can be cut in halves, quarters, or eighths, and glued on the inside face of the cube, thus simulating a unit cell. (MLH)

To hold student interest, distance learning instructors need to think and present ideas visually. Presentations should be limited to three or four key points that would benefit from visual depiction. Visual aids used for presentation may be image-related, concept-related, or arbitrary graphics. Sophistication of visual aid is not as important as…

Investigates the effects of different amounts of realism in visuals and the integration of rehearsal activity into visually-complemented prose instruction. Participants were 128 university students. Findings indicate that different levels of realism in visuals, and overt and covert rehearsal strategies are not equally effective in facilitating…

With both "Cabri" and "Autograph" now venturing into 3D, the dimension that previously was only demonstrated in the classroom with a lot of arm waving and crude wire cages can now be explored dynamically on screen. "Cabri 3D" concentrates on constructions, using the principles of Euclidian geometry, whereas "Autograph" creates objects using a…

The purpose of this study was the development and testing of a novel method for assessment of white blood cell (WBC) identification skills used in the field of Clinical Laboratory Sciences (CLS). A dual format exam was administered to both novices (students) and experts (laboratory professionals). Format 1 was similar to current assessment…

The primary purpose of the present study was to determine whether recent findings documenting the benefits of text-related motor activity on young children's memory for reading passages [Glenberg, A. M., Gutierrez, T., Levin, J. R., Japuntich, S., & Kaschak, M. (2004). Activity and imagined activity can enhance young readers' reading…

Reports results of two studies using physics materials to determine the parameters of pictorial analogies in combination with expository text. Shows that pictorial analogies can improve learning significantly if they are designed properly and used together with the text. Concludes that the analogies should have high structural similarity between…

Provides opportunities for children to develop visual images of the number situations they are exploring in order to develop powerful number sense. Illustrates two visual teaching aids to help young children develop number images. (ASK)

Based in a stream of community-based health promotion activities rather than a fixed framework of hypothesis testing, the study described in this paper tried to solve the problem of the one-sided communication between Japanese health care providers and receivers by visualizing health-related feelings and concepts for both parties involved in the…

This report describes a study of how maps are learned. Subjects (undergraduate students at the University of California) studied a simple map under various conditions and then answered questions about the map and drew the map from memory. It was found that local relations are learned before large-scale relations, that different types of map…
