Joshua Grodotzki Technical University Dortmund, Institute of Forming Technology and Leightweight Components
Joshua Grodotzki manages the group of Profile and Sheet Metal Forming at the Institute of Forming Technology and Lightweight Components, Department of Mechanical Engineering, at the Technical University of Dortmund. Since six years, his research activities center on engineering education topics with a particular focus on the use of digital technologies, such as apps, augmented and virtual reality, and non-classical laboratory formats. Other areas cover non-digital topics, including misconceptions and curriculum development.

Abstract
In the years 2020 - 2023, different concepts of material characterization laboratories as part of a forming technology course in the third bachelor year at the department of mechanical engineering, TU Dortmund University, Germany, have been implemented and evaluated. With the remote experiment, students were able to perform a standard tensile test for steel and aluminum fully autonomously. A so-called human-remote type experiment was used for the in-plane torsion test, where the instructor was equipped with cameras, microphone and head-set, such that students could control the instructor via web and observe the results of their actions in real-time. With the ability to go back to campus, additional experiments, such as the Nakajima test, which is used to characterize the formability in metals, was performed hands-on by the students in the lab. Through a comparative analysis of students’ self-assessment regarding different learning outcomes prior and after the course, it was found that given a choice, students usually prefer hands-on labs over human-remote ones. For digital laboratories, the human-remote lab is the preferred choice over the remote experiment. Analyzing the students’ overall course performance, it was shown that all types of laboratories provide a sufficient teaching input to perform well regarding several metrics tested in the course.
