A common sight in the first 2 years of US medical education is that of a professor speaking in a lecture hall that is only half full. An hour later, in the library or elsewhere, students who did not attend the lecture can be seen wearing headsets, watching the recorded lecture at 2× to 4× speed on a desktop, while looking up reference material on their laptop. This trend should not be surprising, because the much-talked-about “millennial” generation has many distinguishing characteristics—but it is their facility with technology and their attitudes toward learning that stand out and that have changed the educational landscape.
