Reviews "Decisions Decisions", a computer-based simulation for grades 5 through 12 which involves the whole class in making policy decisions on historical and current events with the use of only one computer. Topics of the seven separate simulations are: immigration, colonization, revolutionary wars, urbanization, foreign policy, the…

Presents the listing (TRS-80) for a computer program which derives the relativistic equation (employing as a model the concept of a moving clock which emits photons at regular intervals) and calculates transformations of time, mass, and length with increasing velocities (Einstein-Lorentz transformations). (JN)

Presents a computer program which predicts the weather based on student input of such weather data as wind direction and barometric pressure. Also provides procedures for several hands-on, weather-related activities. (JN)

This program offers a collection of interactive lessons and examples designed to help students learn to spell 2000 words. The program's multimedia tutorial style provides a challenging and enjoyable way to improve spelling skills. In the quizzes, exercises, and games in the program, the student can both hear how the words are pronounced and see…

Graphs equations in two variables using a BASIC screen-sweep program that generates solutions to equations by applying the intermediate value theorem. Provides suggestions for investigations that result in graphs of a butterfly, the Cheshire cat, the Trisectrix of Catalna, E. T. waving goodbye, a praying mantis, and others. (MDH)

Demonstrated is the use of BASIC computer programs to simulate a binomial experiment and test a simple statistical hypothesis. The theoretical results are reached with the third programing attempt. All results, as well as computer programs, are included. (JJK)

IBM has advertised huge reading gains for Writing to Read, an expensive computer laboratory program aimed at improving the reading and writing performance of kindergarten and first grade students. However, the evaluations done to date simply do not support the program's effectiveness at improving young children's reading achievement. (MLH)

Students in an introductory statistics course are often preoccupied with learning the computational routines of specific summary statistics and thereby fail to develop an understanding of the meaning of those statistics or their conceptual basis. To help students develop a better understanding of the meaning of three frequently used statistics,…

A description of a simple interface to enable the interconnection of a random access slide projector and a microcomputer is provided, as well as summaries of the role of slide images as a means of implementing graphic communication and the new activity in graphics as an area of information processing. The microcomputer interface is then detailed,…

Presents short text in French and discusses possible methods of extending word processing to allow text entry, text editing, and hard copy output of foreign characters. Highlights include discussions of using ASCII for English and problems with French, one-character and two-character approaches, and examples in terms of specific microcomputer…

A narcissistic number is a positive integer equal to the sum of its digits raised to an integral power. For example, 15 is equal to 1-cubed plus 5-cubed plus 3-cubed (a narcissistic number of order three). A computer program to find narcissistic numbers up to 10,000 is given and discussed. (JN)

This book seeks to develop, enhance, and expand students' understanding of mathematics by using technology. Topics covered include the advantages of spreadsheets along with the opportunity to explore the 'what if?' type of questions encountered in the problem-solving process, enhancing the user's insight into the development and use of algorithms,…

Discusses a calculation method to approximate pi. Describes how to get an approximation to the circumscribed and inscribed perimeters of regular polygons of n sides. Presents the computer program and result of the approximation. (YP)

Investigates using the microcomputer to develop a sentence parser to simulate intelligent conversation used in artificial intelligence applications. Compares the ability of LOGO and BASIC for this use. Lists and critiques several LOGO and BASIC parser programs. (MVL)

Describes the electrical and material characteristics of a wide variety of sensors and switches, as well as methods for connecting them to computers that are equipped with a joystick interface. Includes a BASIC computer program that facilitates automation of science experiments and storage of data gathered with simple transducers and sensors.…
