"Any questions? No? Great, let's move on." -- Wait time and awkward silence in the classroom

I have no doubt that every educator is familiar with the following situation:

 "Are there any questions?"

"What is a harmonic oscillator?"

 "What is the difference between a metal and an insulator?"

etc.

We ask an (open-ended) question to engage our students and start looking around at their faces in the lecture hall or classroom. Most students seem to look down at their desk or simply stare into space. After what feels like eternity, we decide to break the awkward silence and answer the question ourselves -- or, in the case of the "Are there any questions?"-question, we would say something along the line of "No? Great, let's move on to the next chapter." 

How to maximize your conference experience

Preliminary note: A modified version of this article is going to appear in the IEEE Magnetics Society Newsletter, so please enjoy this sneak peek and do check out the Newsletter if you are interested. 

Through my experience of attending approximately 20 conferences as an active researcher in the fields of experimental condensed matter physics and magnetism, I believe that I am qualified to share some thoughts on the various possible ways to make the most out of any conference, no matter whether you are a young and less experienced researcher or a seasoned professional.

Media hypes affecting physics teaching and a crisis in particle physics?

Today, I would like to share with the readers two interesting, physics education-related topics that have attracted my interest over the course of the last few days. 

Five ways of improving the learning experience for physics students

Prior to launching this blog I had written down numerous bullet points related to topics in physics teaching that I would deem important. In today's post, based on five selected points I would like to discuss how we could improve the learning experience for physics students by implementing changes in the physics curriculum, course syllabi, and teaching methods. Clearly, most the ideas can be traced back to my time as a postdoctoral research in the United States.
