Each chapter begins with a focus on why the topic is important for clinician educators. A review of the available evidence and relevant medical education theory about the topic follows, with examples from specific studies that provide insight into best practices regarding the concepts and topics discussed in the chapter. For chapters focusing on learners, different environments are considered and similarly, if the focus is on the learning environment, attention is paid to the approach to different learners. Each chapter ends with a summary of the primary points from the chapter and concrete examples of how clinician teachers can put the concepts discussed in the chapter into practice. This is an ideal guide for educators in pulmonary, critical care, and sleep medicine.
