The ability to deliver effective and engaging oral presentations is a critical skill for students in all disciplines. Unfortunately, despite the importance of clear communication, scientific presentations are too frequently confusing and boring. In this seminar, students will be introduced to a diverse set of presentation methods and use exercises to apply these techniques to their own work and ideas. The course will also examine the characteristics common to exceptional scientific talks, show how basic design principles can be used to to create more effective visual aids, and discuss the science behind effective communication techniques.
