Sean Gao; Taylor C. Outlaw; Jason G. Liang-Lin; Alina Feng; Reika Shimomura; Jennifer L. Roizen; Charles T. Cox Jr. – Chemistry Education Research and Practice, 2024
This study aimed to analyze second-semester organic chemistry students' problem-solving strategies, specifically focusing on the resources activated while solving problems on E2, E1, and E1cB elimination reactions. Using the theoretical framework by Elby and Hammer, we defined a resource as a unit of information used in the problem-solving…

Crossette, Nathan; Vignal, Michael; Wilcox, Bethany R. – Physical Review Physics Education Research, 2021
Student learning in upper-division thermal physics has not been studied to the same extent as in other courses like electromagnetism and quantum mechanics. Studies addressing reasoning and learning at the graduate level are even more limited. In this study, we conducted think-aloud interviews with eight graduate students involving questions…

Kimberly Vo; Mahbub Sarkar; Paul J. White; Elizabeth Yuriev – Chemistry Education Research and Practice, 2024
Despite problem solving being a core skill in chemistry, students often struggle to solve chemistry problems. This difficulty may arise from students trying to solve problems through memorising algorithms. Goldilocks Help serves as a problem-solving scaffold that supports students through structured problem solving and its elements, such as…

Omarchevska, Yoana; Lachner, Andreas; Richter, Juliane; Scheiter, Katharina – Educational Psychology Review, 2022
Guided inquiry learning is an effective method for learning about scientific concepts. The present study investigated the effects of combining video modeling (VM) examples and metacognitive prompts on university students' (N = 127) scientific reasoning and self-regulation during inquiry learning. We compared the effects of watching VM examples…

Zotos, Eleni K.; Tyo, Jordan J.; Shultz, Ginger V. – Chemistry Education Research and Practice, 2021
Many recent studies document the difficulties that students experience when learning organic chemistry, often due to the complex visualization and reasoning skills required to successfully understand the ways molecules interact in specific environments. Many of these studies call on instructors to improve their teaching strategies to support…

Victoria Borish; H. J. Lewandowski – Physical Review Physics Education Research, 2025
As quantum technologies transition from the research laboratory into commercial development, the opportunities for students to begin their careers in this new quantum industry are increasing. With these new career pathways, more and more people are considering the best ways to educate students about quantum concepts and relevant skills. In…

Petterson, Michael N.; Watts, Field M.; Snyder-White, Emma P.; Archer, Sabrina R.; Shultz, Ginger V.; Finkenstaedt-Quinn, Solaire A. – Chemistry Education Research and Practice, 2020
An understanding of acid-base reactions is necessary for success in chemistry courses and relevant to careers outside of chemistry, yet research has demonstrated that students often struggle with learning acid-base reaction mechanisms in organic chemistry. One response to this challenge is the development of educational applications to support…

Ralph, Vanessa Rosa; States, Nicole E.; Corrales, Adriana; Nguyen, Yvonne; Atkinson, Molly B. – Chemistry Education Research and Practice, 2022
Emphasizing stoichiometry appears to be a norm of introductory chemistry courses. In this longitudinal and mixed-methods study, we examined how the emphasis on stoichiometry in assessments of introductory chemistry impacted educational equity and student learning. Using quantitative methods, we identified mole and stoichiometric conversions as two…

Reinhard, Aaron; Felleson, Alex; Turner, Paula C.; Green, Maxwell – Physical Review Physics Education Research, 2022
We studied the impact of metacognitive reflections on recently-completed work as a way to improve the retention of newly learned problem-solving techniques. Students video recorded themselves talking through problems immediately after finishing them, completed ongoing problem-solving strategy maps or problem-sorting exercises, and filled out…

Langendorf, Ronja; Schneider, Susanne; Klein, Pascal – Physical Review Physics Education Research, 2022
The Hertzsprung-Russell diagram (HRD) is a fundamental representation in stellar physics. It contains information about key properties of stars and allows inferences about stellar evolution. The use of the HRD is an important disciplinary activity in astrophysics. For example, it is particularly important to have a graphical understanding of the…

Tobler, Samuel; Köhler, Katja; Sinha, Tanmay; Hafen, Ernst; Kapur, Manu – CBE - Life Sciences Education, 2022
Undergraduate biology students' molecular-level understanding of stochastic (also referred to as random or noisy) processes found in biological systems is often limited to those examples discussed in class. Therefore, students frequently display little ability to accurately transfer their knowledge to other contexts. Furthermore, elaborate tools…

Popova, Maia; Bretz, Stacey Lowery – Journal of Chemical Education, 2018
Thirty-six students enrolled in Organic Chemistry II participated in individual, semistructured, think-aloud interviews about the factors that contribute to the stability and reactivity of organic species in the context of unimolecular and bimolecular nucleophilic substitution and elimination reactions. The students were provided with the…

Bain, Kinsey; Rodriguez, Jon-Marc G.; Towns, Marcy H. – Journal of Chemical Education, 2018
Zero-order systems provide an interesting opportunity for students to think about the underlying mechanism behind the physical phenomena being modeled. The work reported here is part of a larger study that seeks to characterize how students integrate chemistry and mathematics in the context of chemical kinetics. Thirty-six general chemistry…

Popova, Maia; Bretz, Stacey Lowery – Chemistry Education Research and Practice, 2018
The purpose of this study was to elucidate and describe students' thinking when making connections between substitution and elimination reactions and their corresponding reaction coordinate diagrams. Thirty-six students enrolled in organic chemistry II participated in individual, semi-structured interviews. Three major themes were identified that…

Magana, A. J.; Balachandran, S. – Journal of Computer Assisted Learning, 2017
While it is clear that the use of computer simulations has a beneficial effect on learning when compared to instruction without computer simulations, there is still room for improvement to fully realize their benefits for learning. Haptic technologies can fulfill the educational potential of computer simulations by adding the sense of touch.…
