Describes physics experiments (including speed, acceleration, and acceleration due to gravity) in which students write programs to obtain and manipulate experimental data using the Atari microcomputer game port. The approach emphasizes the essential physics of the experiments while affording students useful experience of automatic data collection.…

The Rockwell AIM 65 is recommended for use in physics laboratories. Among advantages cited are that the basic board can be purchased customized; for example, it can be purchased with or without a printer, power supply, extra memory, and other items. In addition, the computer is basically designed to control equipment and take data from peripheral…

A BASIC computer program was written for an experiment that measures the time of a fall of a ball-bearing dropped through a measured distance. However, the timing subroutine was written in machine language. The reason for using machine language, the machine language program, hardware used, and the experiment are discussed. (JN)

Describes a first-year laboratory course designed to fulfill laboratory objectives of reinforcing lecture material, teaching experimental methodology, developing hands-on skills, and imparting a sense of error. The course's six segments examine: digital electronics with students building a photogate timer; error analysis; linear accelerated…

Studies the simple dynamical system of the pendulum and the chaotic behavior that occurs when the pendulum is both damped and driven. Provides an algorithm and BASIC program for the numerical solution to the differential equations encountered in the discussion. (MDH)

Describes a computer program which plots electric field line plots. Includes program listing, sample diagrams produced on a BBC model B microcomputer (which could be produced on other microcomputers by modifying the program), and a discussion of the properties of field lines. (JN)

Suggests that intuition and visualization are effective methods of introducing engineering principles to pre-engineering students. Describes the development of computer simulation software as part of a "Pre-Engineering College On Disk" course. The computer game helps students visualize the relationship between shell trajectory and its…

Discusses an easy way of interfacing physics experiments to a microcomputer, providing information on the "analog input port" of a BBC microcomputer. Also describes a capacitor discharge experiment with suggestions for several student activities such as investigating decay curve shapes. Program listing is available from author. (DH)

Microcomputers can record laboratory measurements which human laboratory partners can never collect. Simple, harder, and general-purpose interfaces are discussed, with suggestions for several experiments involving an exercise bike, acceleration, and pendulums. Additional applications with pH meters, spectrophotometers, and chromatographs are also…

This section of the journal includes several short notes on science activities and materials for secondary schools. Activities and materials are included that relate to biology, microbiology, microcomputers, chemistry, and physics. (RH)

Describes 17 situations in physics which require students to write computer programs to solve. All the projects are general in nature and require students to have a thorough conceptual understanding of the content to apply the algorithm needed to solve the specific type of problem illustrated. (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)

Described is a computer tutor designed to help students gain a qualitative understanding of important physics concepts. The tutor simulates a teaching strategy called "bridging analogies" that previous research has demonstrated to be successful in one-on-one tutoring and written explanation studies. The strategy is designed to remedy…

Procedures for displaying computer-generated text and graphics to a large audience are inexpensive when a Fresnel-mirror projector is used. Although small liquid-crystal displays (LCDs) can be easily projected, large LCDs require some modification (which is described). Other devices with LCD displays (oscilloscopes, televisions, and pulse-height…

Describes a microcomputer-based, multichannel digital data acquisition system for acoustic signals. Hardware and software considerations are included. (JN)
