Learning is a social experience — it requires interactions and interactivity. The coronavirus pandemic has been a good opportunity to rethink our approach to teaching. Moving some tasks to an online format suggests that many activities that have traditionally been synchronous and instructor-paced, can be made asynchronous and self-paced. Through Perusall, Eric Mazur, Balkanski Professor of Physics and Applied Physics at Harvard University, will demonstrate how to move information transfer and sense-making...

Nanotechnology has enabled the development of nanostructured composite materials (metamaterials) with exotic optical properties not found in nature. In the most extreme case, we can create materials which support light waves that propagate with infinite phase velocity, corresponding to a refractive index of zero. We have developed a variety of in-plane metamaterial designs that permit obtaining a refractive index of zero in the optical regime. We will report on some of the exotic physics of zero-index metamaterials, including strong enhancement of nonlinear optical phenomena, and on flat-...

Why is it that stellar students sometimes fail in the workplace while dropouts succeed? One reason is that most, if not all, of our current assessment practices are inauthentic. Just as the lecture focuses on the delivery of information to students, so does assessment often focus on having students regurgitate that same information back to the instructor. Consequently, assessment fails to focus on the skills that are relevant in life in the 21st century. Assessment has been called the "hidden curriculum" as it is an important driver of students' study habits. Unless we rethink our approach to...
