Using your calculator

Many people see calculators only as a way of producing answers—indeed some people see them almost as a means of cheating, of short-cutting procedures that can and should be carried out in one's head or on paper. However, the calculator can also be a means of learning mathematics more effectively, something you will come to appreciate more. Many previous mathematics students have found that their graphics calculator, used with understanding and intelligence, has become a most effective aid t

Anti-System Politics in Europe: the crisis of market liberalism in rich democracies [Audio]
Speaker(s): Dr Jonathan Hopkin | At this year’s Annual Lecture, which marks the 10th anniversary of LEQS and follows just days after this year’s European parliamentary elections, Jonathan Hopkin will discuss the recent ruptures in the politics of the rich democracies, signalled by electoral instability across Europe, as well as dramatic events like the election of Donald Trump to the US Presidency and the United Kingdom’s vote to leave the European Union. Dr Hopkin argues that these tumult

1.2 Balanced energy intake

There is a need for a certain daily energy intake to allow metabolism to occur in the body. Metabolism means all the chemical reactions occurring in the body and there are two types of process involved: catabolism breaks down larger molecules into smaller ones often with energy release and anabolism is the building up of larger molecules from smaller precursors, often requiring energy. The body requires energy to power anabolic, mechanical (for example, muscle contraction

2.1.1 Loss of submerged plant communities

One of the symptoms of extreme eutrophication in shallow waters is often a substantial or complete loss of submerged plant communities and their replacement by dense phytoplankton communities (algal blooms). This results not only in the loss of characteristic plant species (macrophytes) but also in reduced habitat structure within the water body. Submerged plants provide refuges for invertebrate species against predation by fish. Some of these invertebrate species are phytoplankton-grazers an

5.1 Introduction

The first genetically modified organisms (GMOs) were created in the early 1970s, but for much of the 1980s biotechnology was a phenomenon confined to the laboratory. In 1988, 'vegetarian cheese', the first food product created using GMOs, was introduced in the UK. This cheese was produced using chymosin, an enzyme derived from genetically modified bacteria, rather than the traditional animal product (rennet). Chymosin derived from GMOs is now used to produce 90% of the hard cheeses mad

1.6 The human impact on the atmosphere: the coming of the industrial age

There is no doubt that CO2 is accumulating in the atmosphere. The record from Mauna Loa charts a continuing rise in CO2 concentration since measurements began in 1958, when the level was 315 ppm; the value had reached about 370 ppm by the end of the 20th century, and hit more than 378 ppm in 2004. Important as changes in atmospheric CO2 undoubtedly are (see below), we need to be aware that this is not the whole story of human-induced greenhouse forcing. In par

5.2 Air pollution

There are many popular beliefs about air quality and health. As a child you might have been exhorted to, ‘go out and play in the nice fresh air’. Mountain air is often regarded as being particularly beneficial, especially for those who are recuperating from or suffering some types of respiratory diseases.

14.23 Government Regulation of Industry (MIT)
The objective of this course is to introduce you to the role of government in markets where competitive equilibria “fail.” In this course we will emphasize the importance of market structure and industrial performance, including the strategic interaction of firms. We will examine the behavior of individual markets in some detail, focusing on cost analysis, the determinants of market demand, investment behavior, market power, and the implications of government regulatory behavior.

2 Your own mathematics

It is crucial to remember that you are a learner of mathematics as well as a teacher. In this course you will be asked to undertake some mathematical tasks. The aim of these tasks is not to improve your mathematics, but to give you experience of doing mathematics for yourself—experience that you can reflect upon subsequently. The reflection is used to develop your awareness of the ways that learners deal with mathematical tasks, and how learners' mathematical thinking is influenced by the w

The role of awareness in the teaching and learning of literacy and numeracy at key stage 2
Our starting point is that explicit understanding of key concepts will promote children’s progress in literacy. We argue that this depends on their teachers having explicit knowledge of the concepts which is translated into teaching practice. These ideas are explored in the context of the teaching of morphology and reading comprehension in 50 London primary schools. In our first study, teacher’s explicit awareness and practice of morphology and reading comprehension strategies are documented
