Reviewed are three computer software programs: the Astronomer (astronomy program for middle school students and older); Hands-on-Statistics: Explorations with a Microcomputer (statistics program for secondary school students and older); and CATGEN (a genetics program for secondary school students and older). Each review provides information on:…

Inequalities are considered among the most useful tools of investigation in pure and applied mathematics; yet their didactical aspects have not received much attention in mathematics education research until recently. An important aspect of teaching problem solving at the secondary level deals with the notion of equivalence of algebraic…

Describes the development of a model for delivering the first course in computer programming to large and diverse classes. Presents an integrated approach that emphasizes program-design skills and problem-solving skills, and motivates students to learn by active processes. Team teachers, tutors, and lab demonstrators integrate lectures, tutorials,…

Describes a database courseware using the HyperCard program on the subject of human reproductive endocrinology and feedback mechanisms. Discusses some issues concerning database courseware development. Presents several examples of the courseware display. (Author/YP)

This paper was prepared in response to the Conference Board of Mathematical Sciences recommendations for the preparation of secondary teachers. It shows how using trigonometry as a conceptual tool in spreadsheet-based applications enables one to develop mathematical understanding in the context of constructing geometric representations of unit…

Examines the use of a computer simulation program as a tool to help in the understanding of wave phenomena. After analyzing some of the main difficulties and common misconceptions about waves, features of the "Making Waves" software package are described. Figures showing a typical monitor display are presented. (YP)

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)

Presents an example of mathematics from an algorithmic point of view, with emphasis on the design and verification of this algorithm. The program involves finding roots for algebraic equations using the half-interval search algorithm. The program listing is included. (JN)

Discusses simple interval timers for microcomputers, including (1) the Jiffy clock; (2) CPU count timers; (3) screen count timers; (4) light pen timers; and (5) chip timers. Also examines some of the general characteristics of all types of timers. (JN)

Provides information of various astronomy software. Each entry includes title, source, type of microcomputer on which the program will run and very brief descriptions. (JN)

Presents the listing for a TRS-80 Model III program which illustrates the first law of robotics (all robots must be programed so that none of their actions will be harmful to man). Also discusses the rational for and development of the program. (JN)

Presents a program that provides a structured listing of BASIC computer programs in a text file. Indents for-next loops for better appearance and easier understanding. Lists program and provides for several versions of BASIC. (MVL)

Presents a comparative study of the effects of feedback on students who learned to solve algebraic factorization problems in an intelligent learning environment. Concludes that when the same error comments were used in both experiments, similarities were observed in the learning paths of the respective student groups. Contains 41 references.…

Covers research conducted within the past 10 years on the topic of using computer models and simulations to aid science instruction at the precollege level. The research is categorized into three main areas: (1) students running preprogrammed simulations; (2) students creating dynamic models using modeling environments; and (3) students using…

The integrated compiler of the Turbo Pascal environment allows the execution of a completed program independent of the developed environment and with greater execution speed, in comparison with LOGO. Conversion table of turtle-graphic commands for the two languages is presented. (Author/YP)
