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)…

Studies of the relationship between students' propositional knowledge (as measured by concept mapping tasks) and their study strategies (as measured by self-report questionnaires) for electricity in first-year university courses are described. The effect of propositional knowledge and prior knowledge on both conceptual knowledge and study…

This paper analyzes the hardware and software features that would be desirable in a computer-based semantic network system for representing biology knowledge. It then describes in detail a prototype network of molecular biology knowledge that has been developed using Filevision software and a Macintosh computer. The prototype contains about 100…

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,…

Reports on the relationship between students' propositional knowledge, measured by concept mapping tasks, and their study strategies, measured by self-report questionnaires, as it relates to the concept of photosynthesis as presented in a first-year biology course. Results indicate that involved, purposeful study strategies, prompted by relevant…
