Many physicians and other healthcare professionals have jobs at medical colleges and universities, and their job description include instruction and lecturing. In addition, many board certified physicians are working in university and teaching hospitals, and have the responsibility of teaching physicians in their residency training. Therefore, not only medical instructors working at medical schools and colleges need to learn about and practice instruction methods. The aim of this book is to describe a five-day course which was conducted during November 2021, and aimed at providing the participants the principles of instruction methods. This book is expected to be of interest to medical instructors, professors and physicians working in university and teaching hospitals.
