Abstract
Abstract The apparatus for teaching science and engineering is an interactive multimedia computer system which is used to simulate the performance of scientific experiments on the computer screen. An experiment is a method for determining the value of one experimental parameter by measuring the value of another using an experimental configuration of devices and apparatus. The interactions of the devices and apparatus in the experimental configuration are governed by a relationship among the experimental parameters that define the configuration. The user of the teaching apparatus assembles a pictorial representation of the experimental configuration on the computer screen and interacts with the pictured experimental configuration to simulate the performance of an experiment. The pictured experimental configuration is governed by the same relationship among experimental parameters as the real configuration and thus, the results of the simulated experiment match the results of the experiment performed in the laboratory. Still images and short motion pictures relating to the subject matter of the experiment can be accessed by the user as an aid to his understanding of the subject matter.
