4.4.1 Introduction
This extract is concerned primarily with the chemistry that underpins the operation of the three-way catalytic converter that is placed in the exhaust systems of motor vehicles in order to reduce the emissions of primary pollutants: carbon monoxide, oxides of nitrogen and volatile organic compounds, including hydrocarbons. Discussion of the various effects of these pollutants and the consequent introduction and refinement of ‘automotive emission regulations’ has not been included, nor is the

Learning languages and finding out about other countries can be fun, as well as useful, and this unit is an introduction to the differences in culture and language about which we all need to be aware. There are 10 independent sections: any selection of them can be studied in any order. Some are about why knowledge of other languages and cultures can be important; others are about what it’s like to study a foreign language or to have a career using a foreign language. This unit is aimed at seco
1.6. Listening, reading and language assimilation One assumption that is widely held as axiomatic is that people learn by doing … We seem to have deduced that people learn to speak by speaking and so on. In reality one simply drowns by attempting to swim without some sort of prior preparation and theoretical instruction. Obviously the art of speaking can be improved by practice but the skill of speaking is learnt primarily in a vast complex of other ways. It might 1.4. Encouraging students to think about etymology When is the best time to introduce students to making connections between languages? When introducing them to the new language. When introducing new vocabulary. When developing whole-class reading skills. It is very encouraging to students about to embark on the study of their first foreign language to know that they already possess a working knowledge of some of its vocabulary. English is littered with dir 1.1 1 Why include a global dimension in science education? Western science drew on a world heritage, on the basis of sharing ideas. Sen (2002) The global dimension refers to approaches to education … which focus on global issues, events and interdependence. … pupils will develop … an understanding of different cultural and political perspectives, as well a Introduction There are many compelling reasons for introducing a global dimension in science education. This unit, aimed at teachers in secondary schools explores why the global dimension in science education is so important and how you might incorporate it in your lessons. This unit is from our archive and is an adapted extract from A global dimension to science education in schools (TL_SCIT5) which is no longer taught by The Open University. If you want to study formally with us, you may wish to e Introduction This unit is about the very basic study skills of reading and taking notes. You will be asked to think about how you currently read and then be introduced to a some techniques that may help you to alter the way you read according to the material you are studying. In the second section you will be asked to look at some useful techniques for note taking and how you may apply them to the notes you make.
