Adaptation of acoustic model experiments of STM via smartphones and tablets

Abstract

The importance of Scanning Tunneling Microscopy (STM) in today’s research and industry leads to the question of how to include such a key technology in physics education. Manfred Euler has developed an acoustic model experiment to illustrate the fundamental measuring principles based on an analogy between quantum mechanics and acoustics. Based on earlier work we applied mobile devices such as smartphones and tablets instead of using a computer to record and display the experimental data and thus converted Euler’s experimental setup into a low-cost experiment that is easy to build and handle by students themselves.

Physics Teachers' Acceptance of Multimedia Applications—Adaptation of the Technology Acceptance Model to Investigate the Influence of TPACK on Physics Teachers' Acceptance Behavior of Multimedia Applications

“…Especially in physics, teachers need electronic measuring systems, simulations and animations to perform experiments and explain connections. For some years, smartphones and tablets, which require even more skills from a teacher, have been added as further innovative experimenting devices (Kuhn and Vogt, 2013;Vogt and Kuhn, 2013;González and González, 2016;Crompton et al, 2017;Strzys et al, 2017;Thees et al, 2017;Bano et al, 2018). All these technologies require additional skills for purposeful application in the classroom, which in turn requires knowledge of the technologies to be used.…”
