This article introduces a novel experiment that involves vitrimers, a new type of polymer, in polymer chemistry and physics lab courses for undergraduate students. Vitrimers are permanently cross-linked networks that can be reprocessed under certain external stimuli. Therefore, they combine the advantages of traditional thermoplastics (excellent…

Premo, Joshua; Wyatt, Brittney N.; Horn, Matthew; Wilson-Ashworth, Heather – CBE - Life Sciences Education, 2022
While group work in undergraduate science education tends to have overall benefit, less is known about the specific peer-peer dynamics that optimize learning during group interaction. The current study used peer ratings and self-reported data from 436 students enrolled in team-based undergraduate science courses (biology or chemistry) to determine…

Scaletti, Carla; Rickard, Meredith M.; Hebel, Kurt J.; Pogorelov, Taras V.; Taylor, Stephen A.; Gruebele, Martin – Journal of Chemical Education, 2022
The protein folding reaction is one of the most important chemical reactions in the human body. Yet, despite its importance, it is sometimes omitted from undergraduate courses due to the challenging nature of some of the underlying concepts. To help make key concepts of the protein folding reaction accessible to our undergraduate students, we…

Echeverri Jimenez, Emmanuel Iamsun – ProQuest LLC, 2022
At the molecular level, chemical processes involve the rearrangement of atoms in space and time. Students often struggle with visualizing the 3D spatial characteristics of molecules and transition states, as well as recognizing the dynamic nature of chemistry. Both visual spatial skills and representational competence should be explicitly trained…

Guspatni, Guspatni – Chemistry Education Research and Practice, 2021
Student-generated drawings are known to be effective in building and revealing students' conceptions of chemistry. Some chemistry concepts, moreover, include changes and processes that cannot be merely represented by static drawings. Computer-based animations are needed to represent the dynamics. In this study, 25 chemistry student teachers, who…

Bongers, Amanda; Beauvoir, Berthorie; Streja, Nicholas; Northof, Georg; Flynn, Alison B. – Chemistry Education Research and Practice, 2020
In chemistry, novices and experts use mental models to simulate and reason about sub-microscopic processes. Animations are thus important tools for learning in chemistry to convey reaction dynamics and molecular motion. While there are many animations available and studies showing the benefit of learning from animations, there are also limitations…

Kahraman, Sakip – Canadian Journal of Science, Mathematics and Technology Education, 2023
The study investigated the effects of the use of dynamic computer visualizations (DCVs) integrated with the POE (Predict-Observe-Explain) sequence on learners' understanding and retention of solubility and on their motivation to learn chemistry. In the research, nonequivalent groups pretest--posttest control and comparison group design was used.…

Several traditional chemistry lab experiences were replaced with a problem-based learning (PBL) experience in a university general education, conceptual chemistry course. Students worked in small groups on an authentic chemistry problem in which each student played a different role (Scientist, Engineering, Marketing Manager, Safety Officer, or…

Rodemer, Marc; Lindner, Marlit A.; Eckhard, Julia; Graulich, Nicole; Bernholt, Sascha – Applied Cognitive Psychology, 2022
In this eye-tracking experiment, we compared instructional videos with static signals, dynamic signals and no signaling in a within-subject design. We tracked eye movements from 28 undergraduate chemistry students while they were watching instructional videos about reaction mechanisms in the different signaling conditions. Further, we assessed…

Teplá, Milada; Teplý, Pavel; Šmejkal, Petr – International Journal of STEM Education, 2022
Background: Studies comparing the effect of dynamic and static visualization suggest a predominantly positive effect of dynamic visualization. However, the results of individual comparisons are highly heterogeneous. In this study, we assess whether dynamic visualization (3D models and animations) used in the experimental group has a stronger…

Kelley, Elizabeth W. – Journal of Chemical Education, 2020
Due to the COVID-19 pandemic, education at all levels has temporarily shifted to remote learning, hobbling an integral component of chemistry courses: the laboratory. The chemistry lab is crucial for developing student engagement and learning with hands-on, relevant experiments in a socially dynamic classroom setting. The transition to remote…

The main protease of SARS-CoV-2 is a promising drug target due to its functional role as a catalytic dyad in mediating proteolysis during the viral life cycle. In this study, experimentally proven 14 HIV protease peptides were screened against the main protease of SARS-CoV-2. Fourteen middle and high school "student researchers" were…

Rodemer, Marc; Eckhard, Julia; Graulich, Nicole; Bernholt, Sascha – International Journal of Science Education, 2021
Research in science education agrees that one of the key challenges of learners in the discipline is certainly connecting domain-specific representations to the underlying concepts. One way of supporting students to make applicable connections is using purposefully designed highlighting techniques in multimedia instructions. In order to examine…

Younge, Sinead; Dickens, Danielle; Winfield, Leyte; Sanders Johnson, Shanina – Journal of Chemical Education, 2022
Culturally relevant pedagogy and critical race feminism can be utilized to challenge the inequality and masculine nature of chemistry. Such an approach is needed to increase the representation of Black women in STEM and can be leveraged to create a curriculum that addresses the lived experiences of these individuals. This approach can shift the…
