In our third volume of the Education Theory Made Practical series, we continue to try to close the gap betwen the theoretical world of health professions education and the real world of clinical and classroom teaching. Originally written as a joint venture between the International Clinician Educator blog (https://icenetblog.royalcollege.ca/) and the Academic Life in Emergency Medicine Faculty Incubator program (https://www.aliem.com/faculty-incubator/), this book is a great primer for those seeking to apply theory to their day-to-day teaching. The series was originally posted as a blog series and was subject to open peer review. This book is an edited compendium of these peer reviewed works, which have been reformatted and laid out in a textbook format.
