In this seminar, Dr. William Paolo, Associate Professor in the Dept. of Emergency Medicine, presents the evidence in support of our teaching techniques, especially lectures. Dr. Paolo challenges our common assumptions about lectures, describes ways to improve lectures, and describes how memory and attention affect their efficacy. He notes that we have not achieved the goal of linking learning to patient-reported outcomes. Dr. Paolo also describes the importance of developing "new technologies for new learners, and provides an example, i.e.,"living textbooks" that include wikis, podcasts and blogs to support "free open-access medical education."
