Reviews a chem-study experiment in which students weigh and compare equal volumes of gases and enter their data into a microcomputer. Benefits of using the microcomputer include: (1) data table generation; (2) elimination of calculation errors; (3) student conclusions which are meaningful; and (4) efficient grading time for the teacher. (DH)

Offers suggestions for making good use of a single microcomputer in classes with large numbers of students. Strategies described include in-class demonstrations, laboratory station activities, group activities, enrichment activities, and data collection techniques. Diagrams of room arrangements to accomplish the strategies are included. (BC)

Four ways in which microcomputers can be turned into laboratory instruments are discussed. These include adding an analog/digital (A/D) converter on a printed circuit board, adding an external A/D converter using the computer's serial port, attaching transducers to the game paddle ports, or connecting an instrument to the computer. (JN)

Suggests a microcomputer/mastery-learning combination for more effective use of teacher time and management of records, tests, grading, and student directions. Mastery learning is discussed along with the many advantages microcomputers can provide toward this goal. (DH)

Describes three main areas of computer application in science classrooms, discusses problems of selecting microcomputers (hardware) and programs (software) for classroom use, and evaluates the prospects for successful use of computers in science teaching. (Author/JN)

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…

Discusses the ISCS/FIRN Test Item Database, which contains 10,000 juried science questions that can help teachers prepare tests. Describes the process by which teachers can access the database and download certain questions into their own microcomputer. Provides lists from a sample search done using the various menus available. (TW)
