The number and variety of educational mathematics mobile applications (EMMAs) make it difficult to select mobile applications for mathematics learning and teaching. Therefore, in this study, multi-criteria decision-making (MCDM) techniques, which are effectively used in a wide variety of disciplines, were applied to choose among alternative…

This study investigated the role of online applets in early algebra lessons. The effect of two different types of intervention modules on developing students' early algebraic thinking abilities was compared. The first intervention module involved the use of open applets and real-life contexts (open-real). The second intervention module involved…

There is little empirical data on the extent of home numeracy practice using technology, though previous research shows that home numeracy activities are linked with children's mathematics abilities. This study describes the process of constructing an inventory of digital home numeracy practice (DHNP-i). Parents (n = 126) of elementary children…

This article introduces a set of distance education astronomy laboratory exercises for use by college students and instructors and discusses first usage results. This General Astronomy Education Source exercise set contains eight two-week projects designed to guide students through both core content and mathematical applications of general…

This article gives an overview of the new field of complexity theory which links computer science to mathematics, and ultimately to the solution of theoretical as well as practical problems in society and technology. (Author/MK)

A physical chemistry computer program with seven subprograms (available from the author) was developed to present student questions, evaluate mathematical expressions (calculator mode), retrieve tables, and refresh output on the terminal. Criteria for easily adding new questions are listed and sample output included. (SK)

ENTER: History, geography, consumerism, science facts. COMPUTE: Totals, averages, percentages, etc. READ OUT: Enriched, integrated learning. (Editor)

After studying a unit on probability students "put it all together" by analyzing outcomes of real and computer-simulated games of craps. FORTRAN and APL programs for generation of the games are provided in this article. (SD)

This article describes a one-semester junior and senior level course in applied mathematical optimization for undergraduates which provides the opportunity to test models by doing numerical experiments and to learn to use computer subroutines for solving optimization problems. (MN)

This is a continuing column of the magazine; concern in this issue is on work that might be undertaken in a simple computer appreciation course for pupils aged 15-16. Answers to why to teach computer appreciation and how staffs may be helped are given, including 14 topics that the course would cover. (DT)

Based on the premise that most engineering students will own their own microcomputers, discusses the teaching of circuit analysis, possible directions to be taken in hardware analysis, and impact on the mathematics related to circuit analysis. (SK)

The introduction of an instructional computing strategy at Duke University that led to identification of three levels of user subsets and establishment of equipment clusters is described. Uses of the system in establishing computer literacy and special applications in chemistry, computer science, and the social sciences are reviewed. (MP)

Discusses the use of the recursive method to permutations of n objects and a problem making c cents in change using pennies and nickels when order is important. Presents a LOGO program for the examples. (YP)
