Dépôt de couches minces par thermo-évaporation
Présentation des couches minces et de ses utilisations. Réalisation pratique de l'évaporation par effet Joule sous vide.
Vidéo issue du projet VideoManip dont l'objectif est la réalisation de courtes séquences filmées, montrant des expériences réelles, qui seraient à la fois trop complexes pour être montées et montrées en amphi, et pas assez riches d'enseignement pour justifier un TP de plusieurs heures. Les sciences de l'ingénieur consistent à utiliser un phénomèn
5.7 Summary This section of the unit has made you aware that: science is formed by a community of practice, creating knowledge and requiring a special language for its communication; there is a difference between objective scientific methods and subjective ways of knowing; political power influences scientific discoveries, and scientific knowledge is always socially embedded; public understanding and perception of scien
5.1 Introduction to the social construction of scientific knowledge This section explores how scientific knowledge and scientific literacy can be built up through working in communities of practice (groups of people who work together and share a common language). We also look at issues relating to the ideas of subjectivity and objectivity, and at deductive and inductive thinking. Finally, we explore the public understanding of science by examining how society, in wider terms, constructs or influences scientific thinking and understanding. 4.4 Summary In this section, you have had the opportunity to work on some mathematical activities yourself. This should have enabled you to: reflect on how you approach mathematics and what helps you to work on a piece of mathematics; remind yourself of those pieces of mathematics that you can work at successfully; identify aspects of mathematics that you can strengthen as you work through the later blocks of this unit; 4.1 From awareness to understanding In this section the mathematical content is more obvious as we talk explicitly about what it means to know and to think in mathematics. We will also address your own personal knowledge in the subject. Like any other activity, doing and learning mathematics involves: using and adapting existing knowledge; acquiring and constructing new knowledge through thinking and learning; building up links that enable known t 2.5 Communicating with language It has been suggested that our ‘linguistic competence’ (Chomsky, 1965) consists simply of the ability to construct ‘well-formed sentences’. The sociolinguist Del Hymes (1979) considered this notion to be far too narrow, and proposed the term ‘communicative competence’ to account for speakers’ ability to use language appropriately. Communicative competence lets us know when to speak and when not to speak, how to take turns in conversations and how to start and end 2.1 Language in everyday life Language is an ever-present feature of human life. In the developed world in particular, we are surrounded by language. Radio and television provide a soundtrack to the lives of many people. Written language is part of everything from cereal packets and street signs, to relatively new technologies such as email and text messaging. If you were completely alone, far away from any other people or any kind of human contact, how long would it be before words came into your head, perhaps because of 1.4 Subject knowledge Subject knowledge is a critical factor at every point in the teaching process: in planning, assessing and diagnosing, task setting, questioning, explaining and giving feedback. (Alexander et al., 1992, paragraph 77) Subject knowledge, which lies at the heart of this unit, comes in different forms. One well-known typology (Shulman, 1986) identifies three kinds: Learning outcomes After studying this unit you will have: explored your knowledge, attitudes and feelings in each subject area; begun to identify, in each subject, areas of knowledge where you are confident and others where you need to deepen your understanding; extended your knowledge and understanding of the place that language, mathematics and science have in the everyday life of individuals and societies.

Using the notion of ‘teamwork’, you will be asked to think specifically about the values and beliefs underpinning the following three aspects of practice: developing working relationships with other professionals; sharing information and skills with other professionals; working in cooperation with other profe Acknowledgements Except for third party materials and otherwise stated (see terms and conditions), this content is made available under a Creative Commons Attribution-NonCommercial-ShareAlike 2.0 Licence All materials included in this unit are derived from content originated at the Open University.

Number systems and the rules for combining numbers can be daunting. This unit will help you to understand the detail of rational and real numbers, complex numbers and integers. You will also be introduced to modular arithmetic and the concept of a relation between elements of a set.

The most ‘important and greatest puzzle’ we face as humans is ourselves (Boring, 1950, p. 56). Humans are a puzzle – one that is complex, subtle and multi-layered, and it gets even more complicated as we evolve over time and change in different contexts.
When answering the question ‘What makes us who we are?’, psychologists put forward a range of explanations about why people feel, think and behave the way they do. Just when psychologists seem to understand one bit of ‘who we are’
