Presents a classroom-tested, easy-to-use, multipurpose program (written in Applesoft BASIC) for graphing equations. A complete listing of the program (which is suitable for a wide range of applications in grades 7-12 mathematics classrooms) is included. (JN)

Iteration is the process of doing something repeatedly in a computer program. In LOGO, the most elementary form of iteration is provided by the REPEAT command. This paper explores how programers can use LOGO's extensibility to create more powerful iterative forms than those offered by the REPEAT command. (JN)

Identifies strengths and weaknesses of a computer software package called Rightwriter and concludes that it is easier to learn and costs less than its competitors. (DF)

Outlines the technologies that rural schools have available for the development of expanded curriculum opportunities in high schools. They include: audio teleconferencing, videotape lessons, interactive television, interactive video, and computer networks. Includes a discussion of the problems of sharing. (MD)

Vendors implementing Standard Network Interconnection (SNI) protocols for computer to computer communications can now test their implementation against the Linked Systems Project/SNI Test Facility developed by Library of Congress. The facility is intended to verify correct functioning of SNI protocols for Open System Interconnection (OSI) layers.…

Briefly introduces the programming languages of artificial intelligence and presents information on some of the new versions of these languages available for microcomputers. A tutorial for PROLOG-86, a new microcomputer version of PROLOG, is given. Information on other microcomputer versions of these programs and a bibliography are included.…

Previous work focused on use of computer graphics in teaching thermodynamic phase equilibria for classes I and II. Extends this work to include the considerably more non-ideal phase behavior shown by classes III, IV, and V. Student and instructor response has been overwhelmingly positive about the approach. (JN)

Discusses the dissatisfaction of teachers with using computers in the classroom and argues that the problem is not the computers themselves, but rather the deplorable state of educational software. (SRT)

A recent survey found many teachers are selecting instructional software programs without sufficient research. Outlines four areas to consider when buying instructional software. (MD)

Compares three letter libraries designed for IBM-style personal computers. Finds the quality of the three approximately equal, but rates sample letters as generally poor. (MS)

The author offers information on 11 modification techniques that may make commercial software programs more appropriate for learning disabled students. (CL)

Some techniques used in making animated computer games in order to highlight their mathematical content are presented through specific examples. (MNS)

Discusses students' uses of certain programs, in contrast to writing them. Three programs are discussed: one on nonreal roots, one on dividing polynomials by quadratic polynomials, and one on "unfactoring." (MNS)

Examines problem-solving in selected software, considering what packages really teach and how useful they are in classrooms. Includes a table listing 21 packages with information in such categories as: suggested ages; solving standard logic puzzles; trial/error or predicting outcomes; breaking tasks into smaller parts; drawing conclusions; and…

Reviews software packages under these headings: (1) simulations of experiments; (2) space flight simulators; (3) planetariums; (4) space adventure games; and (5) drill and practice packages (designed for testing purposes or for helping students learn basic astronomy vocabulary). (JN)
