Priemer, Burkhard; Pfeiler, Stephan; Ludwig, Tobias – Physical Review Physics Education Research, 2020
We report the findings of an empirical study that investigated whether the source of data--firsthand or secondhand data gained from lab work experiments--has an influence on students' learning outcomes. Results indicate that students' choice of a correct or incorrect hypothesis for a pendulum lab experiment on the influence of the mass of the bob…

Kaps, Andreas; Stallmach, Frank – Physics Education, 2022
Smartphone-based experimental exercises were incorporated as part of the homework problems in an introductory mechanics course at a university. A quasi-experimental field study with two cohorts design was performed to measure the impact of such exercises on motivation, interest and conceptual understanding. The empirical results on learning…

Schmidkonz, Bertram – Journal of Chemical Education, 2017
Learning how cave formations, such as dripstone, take shape can be a valuable pedagogical tool in chemistry and geochemistry. Grasping the underlying processes requires students to synthesize knowledge of several different topical areas. The activity presented here uses an innovative experiment to connect chemistry concepts with an interesting…

Gross, Katharina; Pawlak, Felix – Online Submission, 2020
The use of ICT in science education offers many opportunities to promote students' learning and experimenting comprehensively. Considering that, it is important not simply to replace traditional media, but to explicitly identify the added value of ICT tools for students and teachers. Especially alternative forms of documenting experiments,…

Ait Tahar, M.; Schadschneider, A.; Stollenwerk, J. – Physics Education, 2019
This article is about the development of an Internet-based remotely-controlled physical experiment, this is a part of the Remotely Controlled Laboratory at the University of Applied Sciences of Cologne known as TH Köln. The main experimental set-up is based on Pohl's Torsion Pendulum which was enhanced by a PXI measurement system and a webcam. In…

Alkilany, Alaaldin M.; Mansour, Sara; Amro, Hamza M.; Pelaz, Beatriz; Soliman, Mahmoud G.; Hinman, Joshua G.; Dennison, Jordan M.; Parak, Wolfgang J.; Murphy, Catherine J. – Journal of Chemical Education, 2017
A simple, reliable, and cost-effective experiment is presented in which students synthesized citrate-capped gold nanoparticles (GNPs), functionalized them with poly(ethylene glycol) (PEG), and transferred the PEG-GNPs from water to the organic phase dichloromethane. The experiment introduces students to nanotechnology with foci on important…

Scharfenberg, Franz-Josef; Bogner, Franz X. – International Journal of Science Education, 2010
Our research objective focused on monitoring students' mental effort and cognitive achievement to unveil potential effects of an instructional change in an out-of-school laboratory offering gene technology modules. Altogether, 231 students (12th graders) attended our day-long hands-on module. Within a quasi-experimental design, a treatment group…
