Kamphorst, Floor; Vollebregt, M. J.; Savelsbergh, E. R.; van Joolingen, W. R. – Science & Education, 2023
Einstein's derivation of special relativity theory (SRT), based on hypothetical reasoning and thought experiments, is regarded as a prime example of physics theory development. In secondary education, the introduction of SRT could provide a great opportunity for students to engage in physics theorizing, but this opportunity is largely being missed…

Alexandra Taraboletti – Journal of Chemical Education, 2024
In response to the shifting modalities of laboratory-based education, particularly amidst the rise of virtual and at-home instruction, we introduce a novel hybrid laboratory module for undergraduate biochemistry and biology courses. Central to this innovative approach is the use of sourdough as a versatile and accessible model organism, enabling a…

Thomas H. Linz; Mario A. Cornejo; Courtney E. Cunningham; Hao T. Mai; Shakila H. Peli Thanthri – Journal of Chemical Education, 2024
A collection of four activities for science outreach events was developed to teach middle school students about the temperature dependence of scientific phenomena. Procedures are described for four interactive demonstrations on phase changes, fluorescence, viscosity effects on diffusion, and conductivity. Each hands-on activity helps students…

Ye Jiang; Xin Sun; Guomeng Zhang; Da Han; Zhengda Yang – Journal of Chemical Education, 2024
The flue gas from waste incineration power plants contains high-level zinc species that may deactivate the catalyst for selective catalytic reduction (SCR) of nitrogen oxides (NO[subscript x]) with NH[subscript 3]. A comparison experiment was designed to investigate the effect of different types and Zn/Ce molar ratios on the performance of…

Timothy K. Osborn – ProQuest LLC, 2024
Concept inventories are widely used in physics education research, yet numerous studies show that concept inventories measure dramatically different learning gains in different demographic groups. Prior studies show that the performance gaps between demographic groups are already present in their preinstruction responses, suggesting that the…

Terence G. Favero – Advances in Physiology Education, 2025
This article describes the implementation of alternative grading (AG) strategies in an upper-division kinesiology and functional human anatomy course. Traditional point-based grading systems can negatively impact student mental health, decrease intrinsic motivation, and hinder learning. To address these issues, a proficiency-based grading approach…
