Describes a course for science education majors that explores the uses of computer-interfaced experiments in a variety of interesting activities. Several examples of biology experiments are given. (ZWH)

ExCELS is a program that supports teachers interested in the use of computer interfacing at the secondary school level. This paper describes an ExCEL-based course developed for science education majors, presents an overview of interface apparatus and how it is used in schools, and gives examples of experiments performed. (LZ)

Described are the apparatus and procedures needed for a demonstration of the measurement of the electrical resistance of metals as a function of temperature using a microcomputer interface. Discussed are materials, apparatus construction, and experimental results. (CW)

This paper describes how computers were employed by workshop participants, the commercial materials used, some of the experiments performed using computer interfaces, and the effect of computer interfacing on the science laboratory. Increased student interest through the study of open-ended experiments is discussed. (CW)
