Illustrates a method used to handle class size experimental data. Demonstrates this method using the SUPERCALC 3A spreadsheet program for an Apple II computer. Details an example of its use. Shows how to eliminate erroneous data. Gives examples of screens and graphical illustrations from the example experiment. (CW)

Describes the use of the Brown scale and reports the results of its use in an experiment. Describes the instrument and details the experiment. Concludes that the Brown scale is a valid and reliable instrument for measuring attitude toward computer instruction. A copy of the instrument is included. (CW)

Contains annotations for resources on the history of computing. Includes resources for technical computing history, general computing history, precomputer era, the impact of computing and series. (CW)

Presents a program written in USCD Pascal that simulates a system routine. Illustrates standard and user defined boolean and string functions and string procedures. Details the processing operations. (CW)

Proposes to modify the procedure proposed by Abelson and diSessa to produce a polygonal path with vertices that lie exactly on an ellipse. Provides a detailed proof. Implements a limiting process to produce the best possible approximation to any ellipse for any given screen resolution. (CW)

Describes direct and indirect voltage input techniques and their applications to voltage measurements with a microcomputer. Details circuitry that can be used for this with a gameport. Gives examples of circuit modifications, application of voltage measurement, and alternatives to this method. (CW)

Provides an introduction to the mathematics and art of the complex plane. Includes two computer programs written in GW BASIC to facilitate a reader's initial investigation. Identifies additional software resources. Stresses the appeal to future scientists, mathematicians, and artists. (CW)

Contains evaluations of two computer software packages, "Simulation Experiments 45-48 in Epstein's Laboratory Manual for Chemistry" and "Maps and Legends--the Cartographer (Ver 3.0)." Includes a brief description, applications, and the perceived strengths and weaknesses for each package. (CW)

Provides a method to use superscripts and subscripts on the screen by using graphics screen modes. Gives two methods and provides a listing of a sample BASIC program. (MVL)

Reviews the goals of laboratory education as identified by the National Science Teachers Association. Describes an Apple II system for the lab. Concentrates on hardware and connections. Stresses the advantages of student-microcomputer interaction in the laboratory setting. (CW)

Identifies pattern recognition as one problem-solving behavior which should be taught to upper elementary and middle school mathematics and science students. Advocates a team-teaching approach with mathematics and science teachers and a learning center in a corner of the classroom. Gives examples of how software could be used. (CW)

Describes a field test of the "Diagnostic Test of Computational Skills." Examines whether or not a computer can efficiently analyze student answers, previously unidentified computational error patterns and errors related to student use of microcomputers. Concludes that this method can be useful for immediate and accurate diagnostic information.…

Surveys the current status of artificial intelligence (AI) technology. Discusses intelligent tutoring systems, robotics, and applications for educators. Likens the status of AI at present to that of aviation in the very early 1900s. States that educators need to be involved in future debates concerning AI. (CW)
