Describes several ways to build data collection devices for microcomputers. The interface devices connect with either the computer's game port or an analog-to-digital converter. Discusses how teachers have designed the equipment and appropriate software to use with the computer in biology teaching. (TW)

Provides ideas for using the same port connection of personal computers to interface with laboratory instruments. Contains specific instructions on how to build transducers. Includes plans and diagrams for thermistors and light meters as well as computer programs for displaying instrument readings on monitors. (TW)

Offers a model of a computer-based evaluation program that can assist in science fair judging. Explains the program's procedures for scoring and its capacities for identifying cases of inconsistent judging. Provides examples of program outputs. (ML)

Discusses the need for quality computer software for science instruction. Argues that very little software is currently available that uses the computer's capabilities to provide quality science instruction. Describes microcomputer tutoring systems under development at the University of Pittsburgh that are intended to significantly add to the…

Describes a chemistry lab experiment in which a microcomputer is used to graph data. In the experiment a catalyst is used to decompose a commercial bleach. The computer's game port is used with a potentiometer to plot the volume of oxygen gas produced versus elapsed time. Courseware information is included. (TW)
