Discussion of laboratory experiment simulation in science and engineering education focuses on the need for authoring systems that can be used to create simulations. An editor for a simulator model containing variables and mathematical equations is presented, and screen displays and data analysis are discussed. (LRW)

Describes a system that combines computer-assisted learning (CAL) with interactive video. It was designed in England for an undergraduate pathology course. Hardware, based on a BBC microcomputer, is described; the design of interactive graphics is explained; and the tutorial design, using an authoring system, is discussed. (26 references) (LRW)
