Discusses basic features and functions of spreadsheet programs and describes additional capabilities (editing, windowing, graphics, and word processing) of two second-generation spreadsheet programs: Lotus 1-2-3 and Symphony. (MBR)

Epicycloids are formed by tracing the path of a fixed point on a circle as it rolls aroung the outside of a larger circle. Examines several possibilities related to epicycloids (and hypocycloids), presenting more mathematical patterns and artistic shapes that result from using several computer programs. Program listings are included. (JN)

Discusses the hardware and software necessary to generate charts and graphs to illustrate numeric data using a microcomputer. The manufacturer, price, operating system, memory requirements, and types of graphs they can produce are given for nine graphics software packages and seven inexpensive plotters. (MBR)

Describes the uses of Lotus 1-2-3 (a spreadsheet-graphics-database program created by Lotus Development Corporation) and Symphony 1.1 (a refinement and expansion of Symphony 1.01 providing memory efficiency, speed, ease of use, greater file compatibility). Spreadsheet and graphics capabilities, the use of windows, database environment, and…

Comparison of dot matrix impact printers details price, matrix density, speed, print sizes, feed width, interface connectors, and true descender characteristics. Dot matrix versus preformed characters, maintenance and repair, installing printers at microcomputer workstations, value comparisons, and descriptions of specific printers are…

Author describes a new use for a computer in a computer-aided graphics course. (PG)

Describes a course to enable students involved in research to gain deeper insight into some of the important areas in engineering. A working knowledge of FORTRAN was the only prerequisite. (DF)

Describes achievement in diagnostic task learning by college sophomores and medical students. (JM)

A comparison between computer and student solutions to a location problem indicates a possible strategy utilizing planner-computer collaboration. (RA)

Presents a two-part system for including communication technology in the business communications class. Phase one is the teaching of the concepts of telecommunications, teleconferencing, computer graphics, and voice transmission. Phase two is the emphasis of classroom activities that reflect these changes. (NRJ)

Provides Logo activities designed for adults and children to use together. Although activities are designed for Terrapin/Krell Logo, modifications are provided for use with Apple Logo or TI Logo (Texas Instruments). "Bugs" are introduced in one activity to demonstrate how they can lead to unexpected results. (JN)

An evaluation of a personal computer was conducted to determine its potential for applications normally assumed to require higher resolution, higher cost graphics devices. Its resolution, stand-alone computing power, and capability to function as a distributed computing element in a time-sharing system are discussed. Six references are listed.…

Describes a program in vegetable gardening developed by Purdue University specialists in horticulture and computer technology. This computer program offers residents of Indiana individual garden plans based on their own specifications. (CT)
