Galloway, Kelli R.; Leung, Min Wah; Flynn, Alison B. – Chemistry Education Research and Practice, 2019
Research has shown that within a traditional organic chemistry curriculum, organic chemistry students struggle to develop deep conceptual understanding of reactions and attribute little meaning to the electron-pushing formalism. At the University of Ottawa, a new curriculum was developed for organic chemistry in which students are taught the…

Kararo, Alex T.; Colvin, Rachel A.; Cooper, Melanie M.; Underwood, Sonia M. – Chemistry Education Research and Practice, 2019
The relationship between chemical structure and physical and chemical properties is essential to chemistry. Studies have shown that students have difficulty using structural representations to predict properties, which is not surprising because of the sequence of inferences that are required for sense-making. However, obtaining a nuanced model of…

Pavlin, Jerneja; Glazar, Sasa A.; Slapnicar, Miha; Devetak, Iztok – Chemistry Education Research and Practice, 2019
The purpose of this paper is to explore and explain students' achievements in solving context-based gas exercises comprising the macroscopic and submicroscopic levels of chemical concepts. The influence of specific variables, such as interest in learning, formal-reasoning abilities, and visualisation abilities, is a significant factor that should…

Sreenivasulu, Bellam; Subramaniam, R. – Chemistry Education Research and Practice, 2019
We report here on an exploratory study done with a sample of university students (N = 140) which sought to explore their understanding of the term 'coordination number', a concept encountered in the topic of transition metals chemistry, through a simple open-ended question. The findings show that the conceptual space related to the conceptions…

Bongers, Amanda; Northoff, Georg; Flynn, Alison B. – Chemistry Education Research and Practice, 2019
Creating and using models are essential skills in chemistry. Novices and experts alike rely on conceptual models to build their own personal mental models for predicting and explaining molecular processes. There is evidence that chemistry students lack rich mental models of the molecular level; their mental models of reaction mechanisms have often…

Cole, Martin H.; Rosenthal, Deborah P.; Sanger, Michael J. – Chemistry Education Research and Practice, 2019
This paper describes two studies comparing students' explanations of an oxidation-reduction reaction after viewing the chemical demonstration and one of two different particulate-level computer animations. In the first study, the two animations differed primarily in the complexity of the visual images. Students viewing the more simplified…

Ferreira, João Elias Vidueira; Lawrie, Gwendolyn Angela – Chemistry Education Research and Practice, 2019
Teachers select multiple representations and adopt multiple visualization approaches in supporting their students to make meaning of chemical phenomena. Representational competence underpins students' construction of their mental models of concepts thus it is important that teachers consider this while developing instructional resources. In…

Sweeder, Ryan D.; Herrington, Deborah G.; VandenPlas, Jessica R. – Chemistry Education Research and Practice, 2019
Simulations have changed chemistry education by allowing students to visualize the motion and interaction of particles underlying important chemical processes. With kinetics, such visualizations can illustrate how particles interact to yield successful reactions and how changes in concentration and temperature impact the number and success of…

Kim, Thomas; Wright, L. Kate; Miller, Kathryn – Chemistry Education Research and Practice, 2019
Students in chemistry often demonstrate difficulty with the principle of resonance. Despite many attempts to mitigate this difficulty, there have been few attempts to examine the root cause of these issues. In this study, students were assessed for their perception of Kekule structures based on perceptual learning theory, which is grounded in…

George-Williams, Stephen R.; Ziebell, Angela L.; Kitson, Russell R. A.; Coppo, Paolo; Thompson, Christopher D.; Overton, Tina L. – Chemistry Education Research and Practice, 2018
The aims of teaching laboratories is an important and ever-evolving topic of discussion amongst teaching staff at teaching institutions. It is often assumed that both teaching staff and students are implicitly aware of these aims, although this is rarely tested or measured. This assumption can lead to mismatched beliefs between students and…

Webb, Jeffrey A.; Karatjas, Andrew G. – Chemistry Education Research and Practice, 2018
Various reasons are attributed to poor student performance in physical science courses such as lack of motivation, lack of ability, and/or the overall difficulty of these courses. One overlooked reason is a lack of self-awareness as to preparation level. Through a study over a two-year period, students at all levels (freshman through M.S.) of a…

Pratt, Justin M.; Yezierski, Ellen J. – Chemistry Education Research and Practice, 2018
Conducting qualitative research in any discipline warrants two actions: accessing participants and eliciting their ideas. In chemistry education research (CER), survey techniques have been used to increase access to participants and diversify samples. Interview tasks (such as card sorting, using demonstrations, and using simulations) have been…

Skagen, Darlene; McCollum, Brett; Morsch, Layne; Shokoples, Brandon – Chemistry Education Research and Practice, 2018
The use of online collaborative assignments (OCAs) between two flipped organic chemistry classrooms, one in Canada and the other in the United States, was examined for impact on learners. The intervention was designed to support content mastery, aid in increasing students' communication skills through chemistry drawing and verbalization,…

Ollino, Mario; Aldoney, Jenny; Domínguez, Ana M.; Merino, Cristian – Chemistry Education Research and Practice, 2018
This study presents a method for teaching the subject of chemical equilibrium in which students engage in self-learning mediated by the use of a new multimedia animation (SEQ-alfa©). This method is presented together with evidence supporting its advantages. At a microscopic level, the simulator shows the mutual transformation of A molecules into B…

Frohock, Bram H.; Winterrowd, Samantha T.; Gallardo-Williams, Maria T. – Chemistry Education Research and Practice, 2018
Students in a large introductory organic chemistry class were given the freedom to choose an organic compound of interest and were challenged to develop an educational object (physical or digital) designed to be shared with the broader public via social media. Analysis of the project results shows that most students appreciated the open nature of…
