This article reports on the findings of a research project whose aim was to support and enhance the teaching of risk at Key Stage 4. An innovative and cross-curricular approach has been used, based on modelling socio-scientific issues using new technological tools, designed specifically to enable the consideration of ethical and social issues,…

The characteristic shape of the normal distribution, one hump and two tails, is discussed. The reasoning is based on variation, combinations, probability, and logarithms. The purpose is to be able to answer some of the "whys" students might ask. (LS)

A method for introducing ideas of probability theory is presented. The method is illustrated by solving a coin tossing" problem. (FL)

This article points out that many students, even of college age, lack familiarity with and confidence about probability problems. Several examples are given, including a "fair game" situation which would probably cause many readers some initial concern. (LS)

Commenting on an article by D. Scott, in Mathematics Teaching 52 (Autumn 1970), He present author shows that it is important to know the distribution of error and not just the maximum error. (MM)

Presents theorems about lines and lattice points, and relates these to combinatorial analysis. (RS)
