Described are two methods which use microcomputers to illustrate the use of the electrocardiogram and the function of the heart. Included are a simulation and a method of collecting live electrocardiograms. Hardware, software, and the use of these systems are discussed. (CW)

Uses a modular approach so the Local Area Network (LAN) can be easily dismantled and reassembled for each class. Notes the course is evolving to keep pace with rapid advances in networking technology although only in its second year. Expands the basic LAN through the addition of second generation personal computers. (MVL)

Discusses under what conditions computer simulations should be used. Considers the aspects and qualities of computer simulations used in simulating science laboratory experiments. Provides suggestions for selecting or designing simulations. Examines the idea of transfer when using simulations. (MVL)

Lists a program for a simulation of Rutherford's gold foil experiment in BASIC for both Apple II and IBM compatible computers. Compares Rutherford's model of the atom with Thompson's plum pudding model of the atom. (MVL)

Reviews seven papers presented by the Technical Committee for Education of the International Federation for Information Processing. Topics consider: undergraduate physics, high school optics, a mathematics lab with LOGO, simulations and modeling for secondary education, computer assisted instruction with biology, and mathematics of tomorrow.
