Direct linkSalvatore G. Garofalo – Journal of Science Education and Technology, 2025
The initial learning experience is a critical opportunity to support conceptual understanding of abstract STEM concepts. Although hands-on activities and physical three-dimensional models are beneficial, they are seldom utilized and are replaced increasingly by digital simulations and laboratory exercises presented on touchscreen tablet computers.…

Roth, Tamara; Scharfenberg, Franz-Josef; Mierdel, Julia; Bogner, Franz X. – Journal of Science Education and Technology, 2020
The integration of scientific modeling into science teaching is key to the development of students' understanding of complex scientific phenomena, such as genetics. With this in mind, we conducted an introductory hands-on module during an outreach gene technology laboratory on the structure of DNA. Our module examined the influence of two model…

Peer reviewedStewart, Gay B.; Stewart, John C.; Slape, Sean; Osborn, Jon – Journal of Science Education and Technology, 1997
Presents a measurement of the time and resources committed to traditional student actions such as reading and working homework. The perception of the educational value of each action for both students and faculty is captured. Basic educational efficiencies are computed for a traditional mechanics course and a nontraditional hands-on Electricity…
