DeCocq, Victoria; Bhattacharyya, Gautam – Chemistry Education Research and Practice, 2019
We report our qualitative study of twenty-four students enrolled in the second-semester of a second-year undergraduate (sophomore-level) organic chemistry course, Organic Two. We asked the research participants to propose the product and electron-pushing mechanism of elementary mechanistic steps in the absence and presence of the corresponding…

Caspari, I.; Weinrich, M. L.; Sevian, H.; Graulich, N. – Chemistry Education Research and Practice, 2018
If an organic chemistry student explains that she represents a mechanistic step because ''it's a productive part of the mechanism,'' what meaning could the professor teaching the class attribute to this statement, what is actually communicated, and what does it mean for the student? The professor might think that the explanation is based on…

Sevian, Hannah; Couture, Steven – Chemistry Education Research and Practice, 2018
Problem solving is lauded as beneficial, but students do not all learn well by solving problems. Using the resources framework, Tuminaro J., and Redish E. F., (2007), Elements of a cognitive model of physics problem solving: Epistemic games, "Physical Review Special Topics-Physics Education Research," 3(2), 020101 suggested that, for…

Eren-Sisman, E. N.; Cigdemoglu, C.; Geban, O. – Chemistry Education Research and Practice, 2018
This study aims to compare the effectiveness of a Peer-Led Team Learning (PLTL) model with that of traditional college instruction (TCI) in enhancing the conceptual understanding and reducing both the state anxiety and social anxiety of undergraduate engineering students in a general chemistry course in a quasi-experimental design. 128 engineering…

Haglund, Jesper; Andersson, Staffan; Elmgren, Maja – Chemistry Education Research and Practice, 2016
Entropy is a central concept in thermodynamics, but has been found to be challenging to students due to its abstract nature and the fact that it is not part of students' everyday language. Interviews with three pairs of engineering students (N = 6) were conducted and video recorded regarding their interpretation and use of the entropy concept, one…

Yuriev, Elizabeth; Capuano, Ben; Short, Jennifer L. – Chemistry Education Research and Practice, 2016
Chemistry is a technical scientific discipline strongly underpinned by its own complex and diverse language. To be successful in the problem-solving aspects of chemistry, students must master the language of chemistry, and in particular, the definition of terms and concepts. To assist students in this challenging task, a variety of instructional…

Graulich, Nicole – Chemistry Education Research and Practice, 2015
Organic chemistry education is one of the youngest research areas among all chemistry related research efforts, and its published scholarly work has become vibrant and diverse over the last 15 years. Research on problem-solving behavior, students' use of the arrow-pushing formalism, the investigation of students' conceptual knowledge and…

Ültay, Neslihan; Durukan, Ümmü Gülsüm; Ültay, Eser – Chemistry Education Research and Practice, 2015
This study aimed to investigate the effect of conceptual change text (CCT) in the REACT strategy for students' conceptions of solutions. A quasi-experimental method was used in the study. The study was carried out in the spring term of the 2012-2013 academic year with 61 freshmen students (aged 18-20 years) studying in the Elementary Education…

Salah, Hazzi; Dumon, Alain – Chemistry Education Research and Practice, 2014
The concept of covalent bonding is characterized by an interconnected knowledge framework based on Lewis and quantum models of atoms and molecules. Several research studies have shown that students at all levels of chemistry learning find the quantum model to be one of the most difficult subjects to understand. We have tried in this paper to…

Madden, Sean P.; Jones, Loretta L.; Rahm, Jrene – Chemistry Education Research and Practice, 2011
This study examined the representational competence of students as they solved problems dealing with the temperature-pressure relationship for ideal gases. Seven students enrolled in a first-semester general chemistry course and two advanced undergraduate science majors participated in the study. The written work and transcripts from videotaped…

Evans, Karen L.; Yaron, David; Leinhardt, Gaea – Chemistry Education Research and Practice, 2008
Even after repeated instruction, first year college chemistry students are often unable to apply stoichiometry knowledge to equilibrium and acid-base chemistry problems. The dynamic and interactive capabilities of online technology may facilitate stoichiometry instruction that promotes more meaningful learning. This study compares a…
