Parikesit, Gea O. F. – Physics Education, 2014
Shadows can be found easily everywhere around us, so that we rarely find it interesting to reflect on how they work. In order to raise curiosity among students on the optics of shadows, we can display the shadows in 3D, particularly using a stereoscopic set-up. In this paper we describe the optics of stereoscopic shadows using simple schematic…

Parikesit, Gea O. F.; Kusumaningtyas, Indraswari – Physics Education, 2017
The acoustics of a vibrating string is frequently used as a simple example of how physics can be applied in the field of art. In this paper we describe a simple experiment and analysis using a clipped string. This experiment can generate scientific curiosity among students because the sound generated by the string seem surprising to our senses.…

Maessen, Martijn F. H.; Fluit, Cornelia R. M. G.; Holla, Micha; Drost, Gea; Vorstenbosch, Marc A. T. M.; de Waal Malefijt, Maarten C.; Kooloos, Jan G. M.; Tanck, Esther – Journal of Educational Issues, 2016
Medical students consider anatomy, neurology, and traumatology as difficult study topics. A recent study showed that the daily quiz "Two Opportunities to Practice per day (TOPday)" positively supported biomedical students in analyzing and solving biomechanical problems. The main purpose of this study was to investigate the effect of…
