Interactive Histogram with Error Graph
This resource consists of a Java applet and expository text. The applet allows the user to construct a histogram by clicking on a number line to generate the sample data. The graph of an error function is shown, either mean square error or mean absolute error.
Interactive Histogram
This resource consists of a Java applet and expository text. The applet allows the user to construct a histogram by clicking on a number line to generate the sample data. The class width can be varied and various summary statistics can be displayed.
Red and Black Experiment
This resource consists of a Java applet and expository text. The applet simulates the red and black experiment in which a player bets on a sequence of Bernoulli trials until a target fortune is reached or the player is ruined. The initial fortune, target fortune, and trial win probability can be varied, and the user can select either of two basic strategies: timid play or bold play.
Smokescreen: A Game about life Online Smokescreen is a cutting-edge game about life online. We all use Facebook, MySpace, Bebo and MSN to keep up with our mates - and we've all heard the stories about parties on Facebook being mobbed, or people getting stalked on MSN. The question is, what would you do
Crops of the Future: A Problem-Based Learning Exercise for the Laboratory
In problem-based learning (PBL), complex, real-world problems motivate students to discover interconnections between important concepts and in doing so acquire essential skills. These skills include teamwork, problem solving, information retrieval and analysis, and communication. The activity presented here suggests a way to add a "hands on" component to PBL by integrating a problem with a guided inquiry exercise. Problem resolution depends on observations made in the laboratory, using probes an
A short quiz on bacterial identification
A Questionmark Perception generated quiz concentrating on the identification of bacteria from visual and descriptive clues. The QTIXML file needs to be opened in QP Authoring Manager, converted to an assessment and exported into your own VLE.

1.12 Conclusion It is clear that there are tensions in the use of the site, in that it attracts quite different audiences. There are also tensions relating to the number of visitors it is logistically possible to accommodate, and the economics of maintaining a viable revenue income. The debate goes on about how best to develop and maintain the site in line with the Trust's stated aims and objectives. There is no definitive answer, and the site will inevitably evolve over time. It is now an attrac

When Art Meets Science
Science and art might sound like vastly different disciplines, but
Dr Tim Wetherell from ANU believes they are both motivated by a desire
to make sense of the world in which we live.
A
sculptor and a scientist, Dr Wetherell talks about his experiences
working with various artists and scientists on a range of
interdisciplinary projects - from the monumental sculptures of body
arts to growing living cells over a computer-generated head.

Geological Perspectives on Climate Change
Throughout Earth’s history, mass extinctions of species were closely
related to physical and chemical changes in the atmosphere and the
oceans. These variations were controlled by heat from the sun, the
distribution of oceans and continents, the extent of ice sheets;
volcanic eruptions and asteroid impacts, air-borne particles, the
eruption of methane and greenhouse effects. Greenhouse episodes were amplified by carbon dioxide and methane
feedback effects from warming oceans and drying ve
Financial Shocks and the Macroeconomy
This lecture was the Sixth Sir Roland Wilson Foundation Lecture.
The lecture expands on the final chapter of Macfarlane's 2006 Boyer Lectures, which suggested that future economic shocks would be financial in origin. In particular it examines the implications of the current credit crisis for economic stability, for the financial security of the household sector and for retirement incomes policies.For more information on the Sir Roland Wilson Foundation go to: http://www.anu.edu.au/endowment
The Eighth H.W. Arndt Memorial Lecture: Rehabilitating the Unloved Dollar Standard
The international dollar standard is an accident of history that greatly facilitates international trade and exchange. But erratic U.S. monetary and financial policies, have upset the U.S. and a world economy thus makes foreigners unhappy. Paradoxically, the asymmetrical nature of the dollar standard also makes many Americans unhappy because they cannot control their own exchange rate. Although nobody loves the dollar standard, it is a remarkably robust institution that is too valuable to lose a
Obesity as a Complex Problem
Obesity has increased dramatically across the world, and there is currently no solution to its control. While obesity is easily understood as the positive imbalance of energy intake and expenditure, this does not explain why it is easy to overeat and underexercise. Explanatory models that feed into energy balance include those of obesogenic environments, thrifty genotype, obesogenic behaviour, obesogenic culture, nutrition transition, political economic structures and biocultural interactions of
Quelles machines pour enseigner la langue ?
This paper first presents a history of Computer-Assisted Learning (CAL), setting its origins in the 1920s with the invention of mechanical learning machines. The use of the computer then allowed the development of different types of language learning activities: comprehension tasks, simulations, etc. However, without the contribution of natural language processing (NLP), these activities are of limited use. We address the problem of the integration of NLP in CALL systems while summing up the cha
