The overriding requirement is knowledge of the subject matter. The general advice is simple: if you are not an expert on a topic, you should enrich your background know- ledge before you start teaching. In this book we help you to locate the most important sources of information you need to study before you start. In addition, we provide expert teachers’ advice on how best to structure teaching—what has worked in their hands. You should not, however, expect that these guidelines will automatically work for you. You have to find your own personal style and use examples of relevance for your audience. It is, neverthe- less, always useful to make sure your teaching follows a predefined logical sequence. The book will help you to set up this structure. Most experienced epidemiologists are able to write and present scientific findings by complying with the established rules for scientific writing. Teaching is different because you also have to establish personal contact. Without per- sonal contact, teaching may well be replaced by reading or web-based courses. Personal contact requires that the teacher wants to teach and that the students are willing to learn, or at least to give it a try. Evaluation of your success as a teacher includes assessment of your knowledge and experience as well as how the teaching was received. Any serious evaluation takes both aspects into consideration. Epidemiology is an old discipline but its concepts and principles are evolving rapidly and, for that reason, a book like this needs frequent updating. Teachers have different ideas as to what the level of sophistication in methods should be and where to focus the attention of the students. We have not sought consensus when inviting the authors to contribute. Science is not driven by consensus but rather by diversity. We advise you to read and make your own judgements and develop your pre- ferred trajectory. But first, see what older and more experienced colleagues have to offer. Then—but only then—you can throw it away. This book is a fourth edition ofTeaching Epidemiology, first published in 1992. The content has changed substantially since the second version (2007). The first edition was published by Oxford University Press and the Commission of the European Communities. Later versions are published by Oxford Univer- sity Press in collaboration with the International Epidemiological Association vi PREFACE and the European Educational Programme in Epidemiology. The second edi- tion of the book was awarded ‘Highly Commended in the Basis of Medicine Category’ at the 2002 BMA Medical Book Awards in London. We would like to thank all authors who agreed to share their experience and knowledge with their less experienced colleagues. Without their contributions there would not have been any book. We also thank Pernille Kümpel and Rikke Sinding for their important administrative support and technical skills. Jørn Olsen Naomi Greene Rodolfo Saracci Dimitrios Trichopoulos Acknowledgements Dimitrios Trichopoulos died 1 December 2014 at 75 years of age. We thank him for his valuable contribution to this book over the years and for his generosity as a teacher, scientist, and friend.
