Provides instructions for "seeding" the random number generator (RND) in Apple computer programs. If RND is not seeded, students would see the same examples, questions, graphics features, or other information each time they turn on the microcomputer and run a program. (JN)

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)

Relates the experiences of a naive computer-using teacher attempting to integrate the microcomputer into a course unit on human anatomy. Based on these experiences, advice is offered to others who are incorporating computers into their courses for the first time. (JN)

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)

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)

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)

Emphasis on interfacing -- the various processes for passing information into or out of computers -- is suggested. Why the Texas Instruments microcomputer is plausible for this is noted, followed by specific interfacing suggestions, including programs for a timer and the assembly language subroutine. (MNS)

An adventure-type computer game in which treasure can be acquired by solving problems in ray optics is described. The program is shorter than most adventures and is designed to run in a 16-K Commodore PET microcomputer with tape cassette input. Program and documentation are available at cost from the author. (Author/JN)

Program listing for a computer game on kinematics is provided. Documentation for the listing (in Microsoft BASIC) and rationale for using computer games in the classroom are also provided. (JN)

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)

Seven possible applications of microcomputers in high school science programs are discussed. They include computers as calculators, computers as black-box number crunchers, computers for teaching computer literacy, computers as blackboards, computer-assisted instruction, computer simulations, and process control. (JN)

Faced with beginning the school year without the necessary chemicals for experiments in a newly adopted chemistry textbook, a department chairperson conceived the idea of supplementing the textbook with simulated experiments on microcomputers. The methodology used to select the appropriate software is described, with suggestions for some new…

Questionnaire responses from 193 high schools indicate that very few science teachers use microcomputers regularly in classrooms. Descriptions of schools/science departments, background information on faculty using microcomputers, and nature/extent of utilization are discussed along with possible causes of limited use and recommendations for…

A Macintosh microcomputer and MacPaint program can be used to quickly make charts of structural formulas that fill standard-sized paper with a minimum of instruction, and smaller drawings or structures or fragments may be inserted into text composed with a word processing program. Shows how this is done. (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)
