Lectures on scientific data, educational lectures, and the various other forms of oral presentation are the basis for every medical meeting. Physicians are not professionally trained in giving lectures. This becomes very obvious when one visits a medical meeting. Often the message of the presentation is lost because of poor preparation, slides that fail to communicate effectively, and a generally unconvincing performance by the lecturer. To give a high-quality lecture that will be remembered for its content and form, one first has to learn some basic rules about preparation, PowerPoint slides, and oral communication. This book will enable the reader to overcome all the common presentation mistakes and to start a new career as a professional lecturer and esteemed faculty member.
