The research aims to: (1) produce a computer program as a learning resource on gas law topics; (2) determine the appropriateness and quality of the computer program; and (3) describe the effectiveness of the computer program to help students in learning the concept of gas law. We employed 4D (define, design, develop, disseminate) models in this…

This article describes how one science teacher based an activity on designing smartphone apps to clearly and concisely communicate the interdependent relationships of a biological ecosystem. The teacher designed the activity to address several aspects of the latest science standards. Students needed to understand their ecosystem and synthesize new…

Shows how electronic spreadsheets can be used in science classrooms for such tasks as ordering and keeping track of supplies and for organizing experiments. Sample printouts of records prepared by use of the spreadsheets are included. (JN)

Reviews a chem-study experiment in which students weigh and compare equal volumes of gases and enter their data into a microcomputer. Benefits of using the microcomputer include: (1) data table generation; (2) elimination of calculation errors; (3) student conclusions which are meaningful; and (4) efficient grading time for the teacher. (DH)

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)

Suggests that students can learn the physics of a musical note by learning how to synthesize sounds on a computer. Discusses ADSR (attack, decay, sustain, and release of a note) and includes a program (with listing) which students can use to examine ADSR on a Commodore 64 microcomputer. (JN)

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)

Discusses a computer interfacing course using Commodore 64 microcomputers; a computer program for radioactive equilibrium; analysis of near infrared spectrum of hydrochloric acid molecules using Apple II microcomputers; microcomputer approach to conductivity titrations; balancing equations with Commodore 64's; formulation of mathematical…

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

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)

Reports on presentations and discussions at a meeting (called Powwow) designed to examine and evaluate the current status of computer use in chemistry and to consider appropriate directions for future developments involving computers in the chemistry curriculum. Also reports on activities of Project SERAPHIM. (JN)

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)

Examines various trends and issues in educational computing. Areas addressed include hardware advances, personal databases, laboratory data handling, graphic displays, national networking (including access of Project SERAPHIM materials through the CompuServe Information Service), software advances, Project SERAPHIM activities, and future…

Describes: (1) two experiments using a laser (resonant cavity for light and pinhole camera effect with a hologram); (2) optical differaction patterns displayed by microcomputer; and (3) automating the Hall effect (with comments on apparatus needed and computer program used); and (4) an elegant experiment in mechanical equilibrium. (JN)

Discusses three trends in computer-oriented chemistry instruction: (1) availability of interfaces to integrate computers with experiments; (2) impact of the development of higher resolution graphics and greater memory capacity; and (3) role of videodisc technology on computer assisted instruction. Includes program listings for auto-titration and…
