Kohen, Zehavit; Herscovitz, Orit; Dori, Yehudit Judy – Chemistry Education Research and Practice, 2020
Facilitating students' chemical literacy is a focal point of current science education. This study examines views of chemists and chemistry teachers on chemical literacy and, more broadly, on scientific literacy of four kinds of stakeholders: scientists, teachers, STEM students, and the educated public. We explored the views of 347 participants,…

Dood, Amber J.; Dood, John C.; Cruz-Ramírez de Arellano, Daniel; Fields, Kimberly B.; Raker, Jeffrey R. – Chemistry Education Research and Practice, 2020
Assessments that aim to evaluate student understanding of chemical reactions and reaction mechanisms should ask students to construct written or oral explanations of mechanistic representations; students can reproduce pictorial mechanism representations with minimal understanding of the meaning of the representations. Grading such assessments is…

Talbert, Lance E.; Bonner, James; Mortezaei, Kiana; Guregyan, Cybill; Henbest, Grace; Eichler, Jack F. – Chemistry Education Research and Practice, 2020
In an effort to improve student conceptual understanding and help students better connect pre-existing knowledge to new ideas, a concept map assignment was implemented in a first-year college level general chemistry course. This implementation included a quasi-experiment that was carried out in discussion group recitation sections within a…

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…

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…
