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…

Advances in computer and interface technologies have made it possible to create three-dimensional (3D) computerized models of anatomical structures for visualization, manipulation, and interaction in a virtual 3D environment. In the past few decades, a multitude of digital models have been developed to facilitate complex spatial learning of the…

Analyzes student discourse in 4 grade-12 lab groups working on microcomputer-based laboratories. Analysis reveals the role the computer plays in the group context and the ways that this context is shaped by the computer. Contains 22 references. (Author/JRH)

Describes two experiments in college chemistry which use microcomputers. One experiment deals with chemical oscillations, while the other involves colorimeter titration with laser excitation and computer-interfaced endpoint detection. (TW)

Describes a technique which gives an automatic and accurate assessment of photosynthetic oxygen liberation with graphical results available immediately. This program takes readings from an oxygen electrode and a photocell simultaneously. The types of results and unique features of the technique are discussed. (ML)

Instruction in Scientific Inquiry Skills (ISIS) is part of a seven-year Air Force effort--the Fundamental Skills Training Project--to design, build, evaluate, and transition advanced computer-aided instruction to the education community. This report describes ISIS 2.0 and presents the results of an initial field evaluation of the software during…

Presents an alternative to the use of a radar to determine how fast an individual can serve a tennis ball. Equipped with a tape recorder and a Macintosh computer, students determine the velocity of a tennis ball by analyzing the sounds and echoes heard on the court. (ZWH)

Uses computers to help students identify variables controlling pendulum period. A program written in BASIC for the Apple computer is provided. The activities are useful for developing science skills, mathematics skills, and computer skills. (PR)

Announces the incorporation of a laboratory information management system (LIMS) into the academic environment. Describes the applications of a computer-automated laboratory system at one university. Stresses the benefits to students of the use of such a system in terms of entry into the industrial environment and to professors in grading. (CW)

Describes a heat capacity experiment designed to provide an interactive environment between the student, the experiment, and the computer. Discusses computer software that has been developed so that the entire interaction can be coordinated from the computer keyboard. (TW)

Effects of microcomputer-based laboratory (MBL) exercises and level of cognitive development on high school biology students' ability to construct and interpret line graphs were investigated. Forty-six students enrolled in general biology classes at a rural high school volunteered to participate in the study. These students were administered…

Identifies specific science skill activities and discusses how they can be enhanced using the microcomputer in a laboratory setting. Highlights the benefits, advantages, and applications of microcomputers in physics laboratories. (ML)

Reports on a study into the effectiveness of implementing an interactive videodisc science lesson on titration into a high school science program. Describes the titration lesson and the equipment used in two chemistry classes. Results were generated from achievement and attitude instruments, along with observational data. (TW)

Discusses the need to design distillation columns that are more energy efficient. Describes a "design and build" project completed by two college students aimed at demonstrating the principles of vapour compression distillation in a more energy efficient way. General design specifications are given, along with suggestions for teaching…

Reports on a study that examined and compared the cognitive effectiveness of a traditional hands-on laboratory exercise with a computer-simulated program on the same topic. Sought to determine if coupling these formats would provide optimum student comprehension. Suggests hands-on exercises be followed by computer simulations as postlaboratory…
