Two examples are given of ways traffic engineers estimate traffic flow. The first, Floating Car Method, involves some basic ideas and the notion of relative velocity. The second, Maximum Traffic Flow, is viewed to involve simple applications of calculus. The material provides insight into specialized applications of mathematics. (MP)

Wind chill is detailed and noted as an estimate of how cold the wind makes a person feel in cold weather. A worksheet master that provides a table of temperatures and wind speeds is provided along with a set of problems. Answers to the brief question set are provided. (MP)

This report illustrates how high school statistics students at the junior and senior year level utilize the TRS-80 microcomputer and the Level II BASIC programing language to handle computations of a least squares problem, where an equation is fitted to empirical data. (MP)

Describes "chemometrics" courses which focus on statistical and mathematical approaches for interpreting complex chemical data. (SK)

Problem posters that focus on the use of information from a chart to find a solution are featured. One poster looks at the prices of picture postcards and is geared for grades one through three. The second poster, designed for levels four through eight, focuses on postage rates. (MP)

Four ideas dealing with applications of telling time are featured. Activities covered include sequencing routine daily events, scheduling appointments, watching television, and calculating elapsed time across time zones. Worksheets suitable for duplication are provided. The activities are considered practical and adaptable to problem-solving…

The article discusses the experiences of the writer when using simple surveying as a practical topic with secondary school children. (Author/MK)

This paper describes some mathematical situations met by young people in the first year or two of their work as junior clerks or business technicians. These are compared and contrasted with the engineering side of industry, with discussion of some possible implications for schools. (Author/MK)

An approach which seeks to stimulate interest in mathematics by enabling a student to use his knowledge in a nontrivial application is discussed. An example of how the approach was implemented is presented with an assessment of the results as measured by student reactions. (Author/TG)

The task of finding the least number and the size of weights necessary to weigh every integral number of pounds from one to 40 is presented as a problem solving activity for elementary classrooms. (MP)

A special calendar chart is presented that can be used to find out what day of the week any date falls on during the 1980s. (MP)

Starting from the energy and degeneracy of the Landau levels of a free-electron gas in a magnetic field, the nonoscillatory term of the Landau diamagnetism is derived for T=O, using elementary algebra only. (Author/JN)

Some examples of typical nonrelevant textbook problems on probability are followed by more complex problems pulled from the real world. The resource used in this report is Newsweek magazine; and is used to help demonstrate that from the very beginning, lessons on conditional probability can have relevance. (MP)

A summary is given of a study undertaken by the National Research Council recommending an increase in the applicability of undergraduate mathematics. (MP)

The NCTM delegation's visit to the People's Republic of China in the fall of 1977 is described. Mathematics education in China is presented in terms of mathematical content taught. (MK)
