The problem of determining the most energy-efficient strategy to use in approaching a traffic light that is sighted at an unknown phase in its cycle is discussed. Included are calculations, results, and conclusions. (KR)

Described are some ways in which individual states code driver's license numbers. The encoding of month, date of birth, year of birth, sex, and others involving elementary mathematics and the use of an elaborate system of hashing functions in describing the first, middle, and last names are discussed. (KR)

Presented is a combinatorial problem based on the Hash House Harriers rule which states that the route of the run should not have previously been traversed by the club. Discovered is how many weeks the club can meet before the rule has to be broken. (KR)

A mathematical model or project analysis that calculates the financial return from home ownership is described. This analysis illustrates topics such as compound interest, annuities, amortization schedules, internal rate of return, and other elements of school and college mathematics up through numerical analysis. (KR)

School mathematics curriculum worldwide has failed to bridge the gap between school mathematics and out-of-school problem-solving activities. Presented is the need for a mathematics curriculum unifying the civil, academic, bureaucratic, and school social domains to prepare students as functional citizens. (MDH)

Discusses people's need for facility in calculating and using mathematical techniques to participate in the understanding and transformation of their society. Topics discussed include the relationship between democracy and education; democratic competence; democracy in a technological society; the role of mathematics in society; and reflective…

Simple connections between prime numbers, methods for obtaining prime numbers, characteristics of prime numbers, and the relationship of primes to high order numbers are discussed. (CW)

Discusses the study of identification codes and check-digit schemes as a way to show students a practical application of mathematics and introduce them to coding theory. Examples include postal service money orders, parcel tracking numbers, ISBN codes, bank identification numbers, and UPC codes. (MKR)

In phase I of an Ohio project, 10 high school teams completed technical projects based on a fictitious manufacturer. In phase II, local industries provided reality-based projects for teams of math, science, and technology teachers and students. (SK)

Argues that the correct use of positive and negative signs in textbooks is often ignored and that this misuse might be because the authors are unaware of some basic rules. (DDR)

A study examined the effects of combining curriculum-based measurement in mathematics computation with teachers' self-monitoring of instructional changes on academic progress of 54 elementary students with learning disabilities and mild mental disabilities. The combination of curriculum-based measurement and self-monitoring resulted in…

Argues that reform in curriculum and instruction should be based on students resolving problems rather than mastering skills and applying them. An alternative is proposed that builds on John Dewey's "reflective inquiry," arguing that this approach would facilitate students' understanding. This proposal is compared with other views on the…

Discusses approaches to teaching mathematical problem solving in the context of number, including encouraging children to write number stories to consolidate their conceptual understanding and technical competence. The use of computers to explore mathematical concepts is discussed, and examples of how number squares can be used are provided. (CR)

A survey of 36 primary-level teachers from five schools for the deaf found that most reported presenting mathematical story problems 1-3 times per week, and presentation method tended to reflect school communication philosophy. Trends in story problem presentation were found to be in accordance with the mathematics grade level taught. (Contains…

In this paper we consider geometrical construction problems and their role in mathematical education. Owing to the main features of construction problems (accuracy in making conclusions, strict structure, rigorous language and constructivistic nature), they can be fruitfully used in teaching mathematics and computer science. We shall try to shed…
