The plate and frame filtration experiment is one of the essential experiments performed by undergraduate students during their practical education. While this experiment often relies on the conventional manual recording of data and calculation, there are frequent problems with data collection because capturing transient data of filtrate volume and…

Explains two approaches to the automatic arrest of a potentiometric titration. (SA)

Microcomputers can perform two distinct functions in high school science classes, providing computer-assisted instruction and serving as tools in experimentation. This report describes a project based on three premises: that science is primarily the process of examining, modeling, and understanding nature; that the best way to learn science is by…

Uses of Zenith Z-100 microcomputers by chemistry students at Clarkson College are discussed. These include: (1) programing; (2) word processing; (3) numerical methods, statistical/plotting programs; (4) laboratory data acquisition and manipulation; (5) simulations; (6) computer assisted instruction; and (7) computer managed instruction. (JN)

Describes the process dynamics and control program developed by the chemical engineering department at the University of California, Santa Barbara. Undergraduate and graduate control courses and real-time computing courses are included. (HM)

Different programs have been developed for the simulation of physics experiments by using TI-57 programmable calculators. Two of these programs, describing the simulation of a successive radioactive decay and the random motion of a gas molecule, are presented. (Author/SK)

Describes a procedure for determining the coefficient of restitution using a microcomputer which collects and sends data to a large computer where analysis is done and graphical output is generated. The data collection hardware and software are described, and results are illustrated. (Author/SK)

Because advanced students had difficulty in interpreting cleavage patterns obtained by gel electrophoresis related to rapid sequencing techniques for DNA and RNA, several formats were developed to aid in understanding this topic. Formats included print, print plus scrambled print, interactive computer-based instruction, and high-resolution…

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)

This ERIC Digest presents a brief description of some applications and findings of the microcomputer in science classrooms. It is suggested that microcomputer simulations are at least as effective as hands-on experiences for some cognitive outcomes and may in fact enhance these outcomes when the simulations are sequenced to follow hands-on…
