Video analysis with a 30 Hz frame rate is the standard tool in physics education. The development of affordable high-speed-cameras has extended the capabilities of the tool for much smaller time scales to the 1 ms range, using frame rates of typically up to 1000 frames s[superscript -1], allowing us to study transient physics phenomena happening…

The increasing complexity of human body models enabled by advances in diagnostic imaging, computing, and growing knowledge calls for the development of a new generation of systems for intelligent exploration of these models. Here, we introduce a novel paradigm for the exploration of digital body models illustrating cerebral vasculature. It enables…

Describes: (1) a FORTH-language, computer-controlled potentiometric titration; (2) coulometric titrations using computer-interfaced potentiometric endpoint detection; (3) interfacing a scanning infrared spectrophotometer to a microcomputer; (4) demonstrations of signal-to-noise enhancement (digital filtering); (5) and an inexpensive Apple…

The use of a microcomputer as the basis of a multichannel analyzer (MCA) system is described. Principles of microcomputer MCA, choice of microcomputer, input-output port, data display, MCA program, and interrupt routine (with flowchart) are the topic areas considered. (JN)

Equipped with simple sensors and software, a microcomputer can become a microcomputer-based laboratory (MBL). Discusses the value of MBL's and provides three programs which preview the new MBL kits available for science classes. A list of commercially available MBL's (with product names, current prices, and other information) is also included. (JN)

Describes hardware and software requirements for interfacing a thermometer probe, via an analog and digital converter, to any Commodore PET, VIC-20, or Commodore-64 microcomputer (or other microcomputers with some modifications). Also describes use of the probe in an experiment measuring enthalpies of reaction to determine enthalpy of formation of…

Topics include fluid mechanics, electricity, crystals, arthropods, limpets, acid neutralization, and software evaluation. (ML)

Microcomputer-based laboratories (MBLs) refer to a laboratory where a microcomputer gathers and displays data directly from the environment. Program listings for a response timer (using game paddles) to illustrate the nature of MBLs are presented. (JN)

Presents 26 activities, experiments, demonstrations, games, and computer programs for biology, chemistry, and physics. Background information, laboratory procedures, equipment lists, and instructional strategies are given. Topics include eye measurements, nutrition, soil test tube rack, population dynamics, angular momentum, transition metals,…

A 16K Sinclair ZX81 microcomputer equipped with an analog to digital board and a Sinclair printer was used to capture data continuously from a total of eight temperature or light sensors. Describes the construction of the peripherals, explains how to connect them together, and provides a program to run the ZX81. (Author/JN)

Evaluates the Measurement Module (TEL-Atomic, Incorporated), a real time data capture and display instrument which (according to the manufacturer) was designed primarily for use in demonstrations. Includes comments on the module's specifications and features, software, documentation, and student laboratory use. The module is compatible with Apple…

This article discusses factors in the design, commissioning, project management, and intellectual property protection of developments within a new clinical anatomy facility in the United Kingdom. The project was aimed at creating cost-effective facilities that would address widespread concerns over anatomy teaching, and support other activities…

Described is a project involving the introduction of microcomputers into the laboratory portion of a college general physics course for data collection and analysis. The results of an evaluation of this program are presented. (CW)

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)

Reviews software packages used in microcomputer-based laboratory (MBL) experiments. They include programs for a precision timer, frequency meter, heat and light experiments, sound experiments, spectrum analysis, biofeedback analysis, and others. Reviews include a brief description, source, current cost, and equipment requirements. (JN)
