1.1.4 Genetic testing of adults
This Unit looks at three different uses of genetic testing: pre-natal diagnosis, childhood testing and adult testing. Such tests provide genetic information in the form of a predictive diagnosis, and as such are described as predictive tests. Pre-natal diagnosis uses techniques such as amniocentesis to test fetuses in the womb. For example, it is commonly offered to women over 35 to test for Down's syndrome. Childhood testing involves testing children for genetic diseases that may not become a p

Key skills assessment unit: Application of number
Numerical and mathematical skills are used to describe and tackle a wide range of problems. These key skills are about understanding when particular techniques should be used, how to carry them out accurately and which techniques should be applied in particular situations. Developing your numerical, graphical and algebraic skills means being able to plan how you are going to use your skills over a period of time, monitoring your progress and then reviewing your approach.

1.4.1: Price ratios
This unit looks at a wide variety of ways of comparing prices and the construction of a price index. You will also look at the Retail Price Index (RPI) and the Consumer Price Index (CPI), indices used by the UK Government to calculate the percentage by which prices in general have risen over any given period. You wil also look at the important statistical and mathematical ideas that contribute to the construction of a price index.

Peer Conversations for e-Learning in the Grid
We take the view of 'learning as a conversational process', and argue that this can be extended to include the notions of peer-group interactions among students, tutors, and even artificial agents. This in turn lends itself to an approach to distributed conversation which builds upon modern Instant Messaging tools, and extends such tools to include what we call enhanced presence: a way of monitoring the availability of (and interacting with) fellow students and tutors at a distance.

Hypermedia as a means for learning and for thinking about learning
This paper is about the design and realization of an experimentation with a hypermedial system, IPER-3, facing the three ‘classical’ problems in the history of mathematics (trisection of the angle, quadrature of the circle, duplication of the cube) and some issues which have developed around them. The aim of the work is to study the opportunities provided by hypermedial systems in dealing with topics of interest for the training of teachers and/or for class work, exploiting the possibility o
