A computer program that simulates the random evolution of a metabolic pathway is given. The program shows that natural selection preserves favorable traits if they occur in a specific sequence. (KR)

This note describes an inexpensive means for making high resolution analog voltage measurements using the parallel printer port of a standard IBM PC or compatible. (PR)

Reviews the use of spreadsheets and gives examples of how they can be adapted for data analysis in a science laboratory situation. Highlights the benefits and limitations of this approach for students. (ML)

Explains how databases can be used to enrich and complement the science curriculum. Provides examples of applications of databases to science activities and experiments. (ML)

Students from five high schools participated in a 2 to 4-week microcomputer based laboratory (MBL) physics curriculum in two groups. One group completed the curriculum entirely online, and the other completed the same curriculum in a traditional classroom setting. Variables were collected to predict student success on a post-unit measure of…

Predicting weather conditions is a topic of interest for students who want to make plans for outside activities. This paper discusses the development of an inexpensive computer-interfaced classroom weather station using an Apple IIe computer that provides the viewer with up to the minute digital readings of inside and outside temperature,…

Described is how spreadsheet and problem solver microcomputer programs may assist students in performing mathematical calculations. Discussed is the application of the equation solver "MathCAD" to various areas in the undergraduate curriculum. (KR)

Discusses the computer's role in schools comparing past expectations with present status. Summarizes the constructionist approach and an opponent's claim. Provides eight examples of innovative approaches for using computers in school. (YP)

Presents a method of analyzing a classic free-fall demonstration using a computer and an audio digitizer. (ZWH)

Reviews Apple computer science programs that are useful in a laboratory setting. Includes laboratory simulations, uses of Apple as a functioning lab instrument, and dissection programs. (ML)

Discusses the possibility of having chemistry students do their own computer programing that could then be used to solve problems in general chemistry. Describes such an effort at Eastern Washington University. Provides examples of some of the student programs and printouts. (TW)

Demonstrates how a spreadsheet program can do calculations, freeing students to question, analyze data and learn science. Notes several popular spreadsheet programs. Gives an example using Lotus 1-2-3 spreadsheets for a sampling experiment in Biology. Shows other examples of spreadsheet use in laboratory activities. (CW)

A total of 59 papers are compiled into these proceedings. The papers are organized alphabetically by each author's last name. A directory of speakers' names and addresses is included. In the index of this publication, papers are listed by session. General sessions are listed first, followed by 21 regular sessions: (1) "Logo and Music";…

Describes a microcomputer program that can be used in teaching the basic physiological aspects of acid-base (AB) balance. Explains how its game format and graphic approach can be applied in diagnostic and therapeutic exercises. (ML)

Describes a spreadsheet computer program which can be used with an Apple Macintosh computer to perform a multitude of calculations. Discusses two types of calculations taught in general chemistry. Demonstrates how to use the spreadsheet to calculate mass percent and the formula of a compound. (TW)
