Kok, Karel; Priemer, Burkhard; Musold, Wiebke; Masnick, Amy – Physical Review Physics Education Research, 2019
In this study with 153 middle school students, we investigate the influence of the number of decimal places from the reading of a measurement device on students' decisions to change or keep an initial hypothesis about falling objects. Participants were divided into three groups, introduced to two experiments--the time it takes a free falling…

Kuhn, Jochen; Lukowicz, Paul; Hirth, Michael; Poxrucker, Andreas; Weppner, Jens; Younas, Junaid – IEEE Transactions on Learning Technologies, 2016
Smart Glasses such as Google Glass are mobile computers combining classical Head-Mounted Displays (HMD) with several sensors. Therefore, contact-free, sensor-based experiments can be linked with relating, near-eye presented multiple representations. We will present a first approach on how Smart Glasses can be used as an experimental tool for…
