Fautch, Jessica M. – Chemistry Education Research and Practice, 2015
The flipped classroom is a pedagogical approach that moves course content from the classroom to homework, and uses class time for engaging activities and instructor-guided problem solving. The course content in a sophomore level Organic Chemistry I course was assigned as homework using video lectures, followed by a short online quiz. In class,…

Burrows, Nikita L.; Mooring, Suazette Reid – Chemistry Education Research and Practice, 2015
General chemistry is the first undergraduate course in which students further develop their understanding of fundamental chemical concepts. Many of these fundamental topics highlight the numerous conceptual interconnections present in chemistry. However, many students possess incoherent knowledge structures regarding these topics. Therefore,…

Olimpo, Jeffrey T.; Kumi, Bryna C.; Wroblewski, Richard; Dixon, Bonnie L. – Chemistry Education Research and Practice, 2015
Two-dimensional (2D) diagrams are essential in chemistry for conveying and communicating key knowledge about disciplinary phenomena. While experts are adept at identifying, interpreting, and manipulating these representations, novices often are not. Ongoing research efforts in the field suggest that students' effective use of concrete and virtual…

Nagel, Megan L.; Lindsey, Beth A. – Chemistry Education Research and Practice, 2015
This paper describes an interdisciplinary investigation of students' usage of ideas about energy from physics in the context of introductory chemistry. We focus on student understanding of the idea that potential energy is a function of distance between interacting objects, a concept relevant to understanding potential energy in both physical and…

Austin, Ara C.; Ben-Daat, Hagit; Zhu, Mary; Atkinson, Robert; Barrows, Nathan; Gould, Ian R. – Chemistry Education Research and Practice, 2015
Student performance in general organic chemistry courses is determined by a wide range of factors including cognitive ability, motivation and cultural capital. Previous work on cognitive factors has tended to focus on specific areas rather than exploring performance across all problem types and cognitive skills. In this study, we have categorized…

Bussey, Thomas J.; Orgill, MaryKay – Chemistry Education Research and Practice, 2015
Biochemistry instructors often use external representations--ranging from static diagrams to dynamic animations and from simplistic, stylized illustrations to more complex, realistic presentations--to help their students visualize abstract cellular and molecular processes, mechanisms, and components. However, relatively little is known about how…

Becker, Nicole; Stanford, Courtney; Towns, Marcy; Cole, Renee – Chemistry Education Research and Practice, 2015
In physical chemistry classrooms, mathematical and graphical representations are critical tools for reasoning about chemical phenomena. However, there is abundant evidence that to be successful in understanding complex thermodynamics topics, students must go beyond rote mathematical problem solving in order to connect their understanding of…

Velasco, Jonathan B.; Stains, Marilyne – Chemistry Education Research and Practice, 2015
It has been established that both tutors and tutees gain from tutoring sessions. However, tutors' benefits may be enhanced or limited depending on the type of behaviours they perform during the tutoring sessions. Although behaviours enhancing both tutor and tutee learning can be promoted by training, generalized tutor training models that are…

Ye, Li; Oueini, Razanne; Dickerson, Austin P.; Lewis, Scott E. – Chemistry Education Research and Practice, 2015
This study used a series of text message inquiries sent to General Chemistry students asking: "Have you studied for General Chemistry I in the past 48 hours? If so, how did you study?" This method for collecting data is novel to chemistry education research so the first research goals were to investigate the feasibility of the technique…

Galloway, Kelli R.; Bretz, Stacey Lowery – Chemistry Education Research and Practice, 2015
The Meaningful Learning in the Laboratory Instrument (MLLI) was designed to measure students' cognitive and affective learning in the university chemistry laboratory. The MLLI was administered at the beginning and the end of the first semester to first-year university chemistry students to measure their expectations and experiences for learning in…

Allen, Gregory; Guzman-Alvarez, Alberto; Smith, Amy; Gamage, Alan; Molinaro, Marco; Larsen, Delmar S. – Chemistry Education Research and Practice, 2015
Open educational resources (OERs) provide a potential alternative to costly textbooks and can allow content to be edited and adapted to a variety of classroom environments. At the University of California, Davis, the OER "ChemWiki" project, as part of the greater STEMWiki Hyperlibrary, was developed to supplant traditional post-secondary…

Rau, Martina A. – Chemistry Education Research and Practice, 2015
Multiple representations are ubiquitous in chemistry education. To benefit from multiple representations, students have to make connections between them. However, connection making is a difficult task for students. Prior research shows that supporting connection making enhances students' learning in math and science domains. Most prior research…

Sevian, H.; Bernholt, S.; Szteinberg, G. A.; Auguste, S.; Pérez, L. C. – Chemistry Education Research and Practice, 2015
A perspective is presented on how the representation mapping framework by Hahn and Chater (1998) may be used to characterize reasoning during problem solving in chemistry. To provide examples for testing the framework, an exploratory study was conducted with students and professors from three different courses in the middle of the undergraduate…

Haglund, Jesper; Andersson, Staffan; Elmgren, Maja – Chemistry Education Research and Practice, 2015
Thermodynamics, and in particular entropy, has been found to be challenging for students, not least due to its abstract character. Comparisons with more familiar and concrete domains, by means of analogy and metaphor, are commonly used in thermodynamics teaching, in particular the metaphor "entropy is disorder." However, this particular…

Buchanan, Malcolm S. – Chemistry Education Research and Practice, 2015
Most Tanzanian Higher Education Institutes do not have the materials and technology to give students a significant practical experience in the sciences. In 2013 Tanzania was rated 159th out of 187 countries for "human development" (United Nations Development Program 2014 Report). In order to supplement their current, limited practical…
