The aims of this project, which is developing a new Advanced Level course for use in English schools, are illustrated by examples of their textual materials. (MM)

Describes an instructional method in secondary school mathematics applicable to physics instruction, to develop conceptual understanding of motion word problems. Distance, rate, and time are defined, used as variables and considered with relative motion as a unifying concept. (JM)

Describes an investigation which introduces the mathematical principles of stream hydraulics and fluvial sediment in a practical context. The investigation has four stages: defining hydrology of the stream; defining channel hydraulics in a study reach; measuring grain size; and calculating transportable grain size and comparing measure stream-bed…

Set concepts are used in this story about a swimming excursion in France, with "real" applications of mathematics presented. (MNS)

The application of the Hamilton method for apportioning seats in the United States House of Representatives is presented based on the 1980 census. It is felt that this method is preferable to the equal proportion method currently used if for no other reason than the greater appearance of fairness. (MP)

The Weight Problem of Bachet de Meziriac is described, which looks for four integral weights to measure every amount between one and forty kilograms. Discussed are generalizations of the problem and analogous problems, solutions of particular cases, and a solution of the general problem. (MP)

Not all data for a program evaluation may be equally valuable, and costs of collection may vary when using several methods to obtain data from several sources. An approach to maximize information yield for a fixed, limited budget using a mathematical technique known as linear programming is described and generalized. (Author/CM)

Some single species and two species interactions in population models are presented to show how credible examples can be used to teach an underlying, common mathematical structure within apparently different concepts. The models examined consist of differential equations, and focus on real-world issues. (MP)

Reports results of a survey of postsecondary students that examines the main difficulties encountered in using elementary algebra in the sciences. (CS)

It is felt measurement experiences in the elementary grades should include everyday application situations. The activities presented are divided into linear measurement and area measurement categories. The use of the human body as a reference for estimation is stressed throughout. The activities described aim to broaden and extend children's…

The material focuses on two posters that provide motivational problem-solving activities with money, in particular on experiences related to making change. Suggestions are given for ways to go further with the posters and extend pupil explorations. The activity posters are designed to maximize the possible answers. (MP)
