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)

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)

Describes the algorithm used to select a simple random sample of certain size without having to list all possible samples and a justification based on Pascal's triangle. Provides testing results by various computers. (YP)

Mathematical techniques used to solve geological problems are briefly discussed (including comments on use of geostatistics). Highlights of conferences/meetings and conference papers in mathematical geology are also provided. (JN)

Describes the creation of a company purchase order complete with the names of items to be purchased, cost, quantity, discounts, sales tax, and balance due. It requires students to apply their knowledge and understanding of percentages and also gives students an opportunity to understand the mathematics they use with algebraic formulas. (AIM)

The impact and role of social needs, including computer technology, on the secondary school mathematics curriculum are considered. Their role in the American curriculum, mathematical applications, institutionalized needs, and alternatives are discussed. (MNS)

Suggests a method treating geometric optics using a microcomputer to do the calculations of image formation. Calculations are based on the connection between the composition of lenses and the mathematics of fractional linear equations. Logic of the analysis and an example problem are included. (JM)

An applications problem, which illustrates an important technique in mathematical applications, is presented and discussed. (MK)
