The recent advancement of large language models presents numerous opportunities for teaching and learning. Despite widespread public debate regarding the use of large language models, empirical research on their opportunities and risks in education remains limited. In this work, we demonstrate the qualities and shortcomings of using ChatGPT 3.5 for physics task development by prospective teachers. In a randomized controlled trial, 26 prospective physics teacher students were divided into two groups: the first group used ChatGPT 3.5 to develop text-based physics tasks for four different concepts in the field of kinematics for 10th grade high school students, while the second group used a classical textbook to create tasks for the same concepts and target group. The results indicate no difference in task correctness, but students using the textbook achieved a higher clarity and more frequently embedded their questions in a meaningful context. Both groups adapted the level of task difficulty easily to the target group but struggled strongly with sufficient task specificity, i.e., relevant information to solve the tasks were missing. Students using ChatGPT for problem posing rated high system usability but experienced difficulties with output quality. These results provide insights into the opportunities and pitfalls of using large language models in education., Comment: 10 pages, 3 figures, 3 tables

Fragen der Bioethik spielen eine entscheidende Rolle bei persönlichen Entscheidungen und in politischen Zusammenhängen. Das Ziel dieses Booklets ist es, eine Einführung in die zentralen Problemfelder der Bioethik zu geben und dabei hauptsächlich die Schnittmenge zwischen Ethik und Technologie zu fokussieren. Nach dem Lesen des Booklets sind Leser_innen mit den konzeptionellen Werkzeugen ausgestattet, die es braucht, um die wichtigsten Debatten in Ethik und Technologie sowie die wichtigsten Positionen im Diskurs zu verstehen und einen eigenen Standpunkt einzunehmen. Das Booklet ist in fünf Themen untergliedert: Künstliche Intelligenz, Robotik, Menschliche Verbesserung, Gentechnik und Umweltethik sowie Entwicklungen in den Neurowissenschaften. Hierbei werden den Kontroversen in diesen Themenfeldern besondere Aufmerksamkeit gewidmet und verschiedene Beispiele angeführt., Bioethical questions have a crucial role both in people’s personal choices and in the political domain. The aim of this booklet is to introduce you to the main controversies in contemporary bioethics, especially to those concerning the intersection between ethics and technology. At the end of reading the booklet, you will be equipped with the conceptual tools required to understand the main debates in ethics and technology and the most relevant positions in the debate. Hopefully, you will be also able to take your own stance on these subjects. As you see this booklet is organised around five themes: artificial intelligence, robotics, human enhancement, [genetic] engineering and environmental ethics and developments in neuroscience. Particular attention will be paid to the “controversies” over these topics, and different examples will be brought forth.

The controlled scaling of diamond defect center based quantum registers relies on the ability to position NVs with high spatial resolution. Using ion implantation, shallow (< 10 nm) NVs can be placed with accuracy below 20nm, but generally show reduced spin properties compared to bulk NVs. We demonstrate the augmentation of spin properties for shallow implanted NV centers using an overgrowth technique. An increase of the coherence times up to an order of magnitude (T_2 = 250 ��s) was achieved. Dynamic decoupling of defects spins achieves ms decoherence times. The study marks a further step towards achieving strong coupling among defects positioned with nm precision., 10 pages, 3 Figures
