Describes an undergraduate laboratory project that combines microprocessor programing, interfacing, and system design to produce an inexpensive multichannel analyzer. (Author/CS)

Two promising new technological tools for science education are described: microcomputer-based laboratories and science telecommunications networks. Explained are the benefits of these tools for students with learning disabilities (including emphasis on nonverbal images and improvements in student focus and communication skills) and guidelines…

The article discusses the importance of instruments in science and technology and describes the development, operations, uses, and software of the Universal Laboratory Training and Research Aid (ULTRA), a portable talking laboratory computer that will enable visually impaired students to perform independently important instrumental measurements…

In a modular approach, instruments are considered as systems composed of modules, each module performing a particular function. Examines process of relating specifications for instruments to those for particular modules, effect of microcomputers on modular approach, and extension of the approach to such devices as "hyphenated" or tandem…

Presents the uses of pocket calculators, programmable calculators, and microcomputers in teaching of statistical physics in unit 9 of the Nuffield advanced physics course. (SK)

Understanding the fundamentals of data acquisition and control is an important part of learning about the use of small computers in chemistry. Data acquisition and control principles can be taught at moderate equipment cost using micrcomputer game ports. Therefore, the components of the Apple II microcomputer game port are described. (JN)

The "Measurement Module" is a device which records measurements for microcomputer input. Construction of the device, software, and uses in physics experiments and demonstrations are discussed. (JN)

Describes a microcomputer-based multichannel analyzer (MCA) in which the front end is connected to a microcomputer through a custom interface. Thus an MCA System of 1024 channel resolution, programmable in Basic rather than in machine language and having moderate cost, is achieved. (Author/SK)

In this paper a hardware/software system is described which permits the use of the Radio Shack TRS-80 Model I as a tachistoscope in perceptual-cognitive research. Hardware requirements and configuration, problems in developing software routines to handle reaction and stimulus timing using the TRS-80, and the development of a routine for…

The Apple game port has two types of inputs: the paddle input and the button input. Scientific applications of these input-output units are discussed, examining analog inputs (potentiometers, thermistors, and photoresistors), single bit digital inputs, and single-bit outputs. (JN)

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…

Describes an apparatus that uses a microcomputer as a timing device in which the Coefficient of Restitution (COR) is measured. Diagrams of a circuit for timing measurements and a flow chart of a program that measures COR are provided. A list of COR for some common objects is also included. (CS)

Presents details of anodic stripping analysis (ASV) in college chemistry laboratory experiments. Provides block diagrams of the analyzer system, circuitry and power supplies of the automated stripping analyzer, and instructions for implementing microcomputer control of the ASV. (CS)

Describes an inexpensive and versitile interface which can be readily adapted to many on-line experimental projects in scientific fields by educators who are not computer experts. Hardware and software requirements are noted. (JN)

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)
