Artificial intelligence and other novel technologies in physics education

We are living in a time of significant technological advances and breakthroughs. Increasing computational power facilitates extensive numerical simulations of material physics, astronomical objects such as black holes, weather and climate phenomena, and the dynamics of a global pandemic that we have been going through for a couple of years. Artificial intelligence based chatbots such as ChatGPT by OpenAI appear to have a disruptive impact on science, technology, engineering and mathematics (STEM). Data science and big data are more established concepts that have already found their way into academic research as well as industrial applications. Quantum computing and brain-inspired computer chips are further examples of potentially disruptive technologies. Virtual reality and the so-called metaverse are expected to become increasingly sophisticated and relevant, too. 

Teaching and communicating magnetism

This is a reprint of an article that I have written for the IEEE Magnetics Society Newsletter (November 2022 issue, edited by Jia Yan Law). Please do check out the Newsletter if you are interested in contents related to magnetism, technology, activities of the Magnetics Society as well as announcements of conferences, awards and events.

Nowadays, the majority of people are likely to encounter magnetism in their everyday lives, be it by simply seeing the magnets on their refrigerator door, using magnetized screwdrivers, navigating with a compass, swiping a credit card, undergoing an MRI scan, or saving an image file on their computer's magnetic hard drive. Of course, in the IEEE Magnetics Society, we have a much closer and more professional relationship with the world of magnetism, for instance, by conducting fundamental research or driving the evolution of magnetism-based technologies. This places us in an optimal situation to teaching and communication outreach in the field of magnetism!

12 questions every physics department should ask themselves

Here are 12 questions that every physics department should ask themselves in regard to teaching and the educational curriculum: 

Having the right mindset for a physics degree

Recently, I had a nice discussion with a colleague about the mindset of undergraduate physics freshmen (i.e., first-year) students. This conversation has inspired today's blogpost on the very same topic. 

Many things are different at a university as compared to high schools. Physics students oftentimes feel overwhelmed during their first semesters at college. Professors are rushing through the course material, homework is due every week in multiple classes, and a major part of the fellow students appear to be geniuses. They seem to grasp even complex contents very quickly, do not need to spend much time on their homework and ask a lot of smart questions during the lectures. One might get the impression that they do not need to work hard to pass exams and achieve their goals. These are only a few examples of the mindset that many students tend to develop. I would like to argue that such thoughts are largely unfounded and are making life unnecessarily harder for many students.

Thoughts and conversations on teaching during a scientific conference

Last week, I attended the annual conference on Magnetism and Magnetic Materials (MMM) which took place in Minneapolis (United States). While the central topics of this conference were all related to cutting-edge research in the field of magnetism, I still had the chance to think and talk about teaching physics and materials science. Therefore, in today’s blogpost, I would like to touch on a few of my thoughts and conversations.

More resources for teaching methods and materials

As the beginning of the winter semester 2022/23 is approaching here in Germany, we are currently in the process of finalizing preparations for our teaching activities. This is yet another reason why I am dealing with physics education these days and therefore I would like to share a few more interesting resources that I stumbled upon.

The teaching statement

Recently, I have talked to a friend about the application process for faculty positions in the United States and Germany. While in the US it is very important to write substantial and convincing statements on teaching as well as on diversity, equity and inclusion, it is not that common in Germany and other European countries. From my experience, even if it is required, both the applicants and the search committee do not seem to take such statements very seriously. Of course, in the US it also depends on the specific university, but in general I would contend that the aforementioned documents play a much bigger role in the States. As I argue quite often on this blog, I think that the importance of teaching skills of future faculty is highly undervalued and should be at least as important as the research profile of an applicant. Obviously, it is hard to quantify a person's teaching skills, but I think that a teaching statement and a teaching demonstration are appropriate ways to better assess an applicant.

Declining student enrollment numbers in physics

Today, I had a look into the most recent statistics about physics undergraduate and graduate student enrollment numbers at German universities. Typically, these statistics are published each year in the "Physik Journal", which is a monthly magazine published by the German Physical Society (DPG, Deutsche Physikalische Gesellschaft). You can find the current statistics here.

Is there a need for teaching faculty in Germany?

In the United States and several other countries, it is common practice that introductory lectures are being held by teaching faculty, i.e., lecturers and teaching professors. In physics departments, this includes classes such as "Introduction to Experimental Physics" (classical mechanics, electricity and magnetism, thermodynamics, optics). Higher-level classes as well as electives, however, are often taught by "regular" faculty who only devote a certain fraction of their working hours to teaching while also being involved in research and service activities. By contrast, in Germany also the introductory classes are taught by the aforementioned "regular" professors, and typically no additional teaching faculty are hired by the universities. Obviously, there are advantages and disadvantages to each of these two distinct approaches. For example, hiring teaching faculty leads to additional costs for the university, but on the other hand one might argue that, on average, their higher enthusiasm for teaching and the fact that they solely focus on their classes leads to a greater success in the students' learning experience. Unlike "regular" professors who may regard teaching as an obligation, teaching faculty usually have a strong passion for teaching and do not have many other duties that would distract them from preparing their classes. 

Hiring teaching assistants for an introductory physics class

After interviewing a few candidates for teaching assistant (TA) positions within the framework of our introductory experimental physics (classical mechanics and thermodynamics) class for freshmen this week, I have had some new thoughts on teaching and learning physics in higher education, especially with regard to TAs and their significance. In the following, I will discuss some of these thoughts.
