Makes the case that geologic fieldwork requires more than knowledge of basic skills learned in the standard undergraduate curriculum. Argues that synthesis of the skills into a schema must be done before one can address the kinds of problems that arise when doing field investigations. Argues for the use of descriptive geometry and trigonometry in…

Reading is fundamental to learning. Vital to learning is memory, which is the mental faculty used to retrieve what was read and understood. The human brain is about the size of a grapefruit and weighs about as much as a head of cabbage. The cerebral cortex is a kind of problem-solving and memorizing device. The hippocampus plays a critically…

Imagery has a significant role in cognitive development. Reading research has established the fact that good readers image spontaneously and that there is a high interrelationship between overall preference for a story, the amount of text-related imagery in the story, comprehension, and recall. Imagery researchers agree that everyone is capable of…

An internal cognitive variable--mental imagery representation--was studied using a set of three information-processing strategies under external stimulus visual display conditions for various learning levels. The copy strategy provided verbal and visual dual-coding and required formation of a vivid mental image. The relational strategy combined…

Presents a historical overview of visualization as a cognitive strategy in human creativity, discovery, and problem-solving. Highlights include visualization as a cognitive strategy for solving everyday problems; visualization by scientists and inventors; counter examples; and implications for multimedia learning environments, instructional…

Defines personal axioms as deeply held beliefs of individuals about themselves and their world that determine their activities, interests, and performance. Discusses the role of the teacher with regard to cognitive restructuring techniques that may help students change negative personal axioms and free themselves to learn more efficiently. (JHZ)

Describes the development of an electronic textbook in human physiology at the Georgetown University Medical Center Library that was designed to enhance learning and visualization through a prototype knowledge base of core instructional materials stored in digital format on Macintosh computers. The use of computers in the medical curriculum is…

Conclusions derived from drawing research indicate that young children can be trained to see and respond to the distinctions of their observation and that these distinctions can enrich their drawing experiences. These distinctions include spatial information obtained from observation. Three basic factors influence young children's spatial…

Current issues in educational communications and technology are addressed in this collection of 35 papers, in which research reports predominate. Topics discussed include factors related to the learner, e.g., field dependence/independence, reading ability, learning strategies, and cognitive style. Presentation format and media and stimulus…
