A small set of relationships has been identified which appears to be sufficient for describing all molecular and cellular reactions and structures discussed in an introductory biology course. A precise definition has been developed for each relationship. These 20 relationships are of four types: (1) analytical; (2) spatial; (3) temporal; and (4)…

A major goal of science education is to turn novices (students) into experts (scientists or science literates) with a minimum amount of pain, effort, and time. However, transfer of biology knowledge from instructor to student usually results in a loss of the rich interconnections that an expert has. The papers in this set describe efforts to…

Designed to focus attention on the design process in such computer science activities as information systems design, database design, and expert systems design, this paper examines three main phases of the design process: understanding the context of the problem, identifying the problem, and finding a solution. The processes that these phases…

Relationship between the social world and individual knowledge acquisition is explored. A general theory predicated on the assumption that social interaction is the driving force behind knowledge acquisition is postulated and then formulated as a model. A selection of results pertaining to social learning are presented. (Author/MBR)

Summarizes findings of a collection of research studies at the University of Aberdeen (Scotland) aiding fundamental understanding of knowledge representation and its applications. Issues arising when a knowledge representation system is incorporated into an authoring language are discussed, including the problems of exteriorization, metacognition,…

This study investigated the speed of encoding and rotation of images during simple spatial rotational operations to discover any similarities or differences in groups of differing spatial ability. This project was subdivided into five basic subproblems. First, research was done to arrive at a simple, easily testable information processing model…
