Direct linkKlein, Geoffrey C.; Carney, Jeffrey M. – Journal of Chemical Education, 2014
Communication and critical thinking skills are integral to the undergraduate chemistry major. A bookend, two-course model has been implemented to supplement chemistry subfield knowledge with the development of these skills. The third-year course introduces the chemical literature and addresses these skills through the synthesis of a literature…

De La Rosa, Paul; Azurin, Katherine A.; Page, Michael F. Z. – Journal of Chemical Education, 2014
This laboratory investigation challenges students to synthesize, analyze, and compare viable alternative fuels to Diesel No. 2 using a renewable resource, as well as readily available reagents and supplies. During the experiment, students synthesized biodiesel from soybean oil in an average percent yield of 83.8 ± 6.3%. They then prepared fuel…

Magana, Alejandra J.; Taleyarkhan, Manaz; Alvarado, Daniela Rivera; Kane, Michael; Springer, John; Clase, Kari – CBE - Life Sciences Education, 2014
Bioinformatics education can be broadly defined as the teaching and learning of the use of computer and information technology, along with mathematical and statistical analysis for gathering, storing, analyzing, interpreting, and integrating data to solve biological problems. The recent surge of genomics, proteomics, and structural biology in the…

Loertscher, Jennifer; Green, David; Lewis, Jennifer E.; Lin, Sara; Minderhout, Vicky – CBE - Life Sciences Education, 2014
Threshold concepts (TCs) are concepts that, when mastered, represent a transformed understanding of a discipline without which the learner cannot progress. We have undertaken a process involving more than 75 faculty members and 50 undergraduate students to identify a working list of TCs for biochemistry. The process of identifying TCs for…

Baseden, Kyle A.; Tye, Jesse W. – Journal of Chemical Education, 2014
Density functional theory (DFT) is a type of electronic structure calculation that has rapidly gained popularity. In this article, we provide a step-by-step demonstration of a DFT calculation by hand on the helium atom using Slater's X-Alpha exchange functional on a single Gaussian-type orbital to represent the atomic wave function. This DFT…

Bowlin, Melissa S.; McLeer, Dorothy F.; Danielson-Francois, Anne M. – Advances in Physiology Education, 2014
Evolutionary history and structural considerations constrain all aspects of animal physiology. Constraints on invertebrate locomotion are especially straightforward for students to observe and understand. In this exercise, students use spiders to investigate the concepts of adaptation, structure-function relationships, and trade-offs. Students…

Tang, Hui; Kirk, John; Pienta, Norbert J. – Journal of Chemical Education, 2014
This paper includes two experiments, one investigating complexity factors in stoichiometry word problems, and the other identifying students' problem-solving protocols by using eye-tracking technology. The word problems used in this study had five different complexity factors, which were randomly assigned by a Web-based tool that we developed. The…

Novick, Laura R.; Schreiber, Emily G.; Catley, Kefyn M. – Journal of Research in Science Teaching, 2014
With applications of Tree of Life data becoming ever more prevalent in everyday contexts, tree thinking has emerged as a vital component of scientific literacy. This article reports a study testing the hypothesis that instruction in natural selection, which is the primary focus of US evolution education at the high school and introductory college…

Goess, Brian C. – Journal of Chemical Education, 2014
A two-semester second-year introductory organic chemistry sequence featuring one semester of accelerated organic chemistry followed by one semester of bioorganic chemistry is described. Assessment data collected over a six-year period reveal that such a course sequence can facilitate student mastery of fundamental organic chemistry in the first…

Lewis, Scott E. – Journal of Chemical Education, 2014
Validity of educational research instruments and student assessments has appropriately become a growing interest in the chemistry education research community. Of particular concern is an attention to the consequences to students that result from the interpretation of assessment scores and whether those consequences are swayed by invalidity within…

Hua, Olivia; Shore, Bruce M. – Higher Education Research and Development, 2014
Professors endorse a symbiotic relationship between research and teaching, but empirical evidence supporting this relationship is inconsistent. Many studies operationalized research and teaching too narrowly to detect the believed relationship. Semi-structured, in-depth interviews were conducted with 27 chemistry professors from a large…

R. – CBE - Life Sciences Education, 2014
There is widespread agreement that science, technology, engineering, and mathematics programs should provide undergraduates with research experience. Practical issues and limited resources, however, make this a challenge. We have developed a bioinformatics project that provides a course-based research experience for students at a diverse group of…

Cahill, Michael J.; Hynes, K. Mairin; Trousil, Rebecca; Brooks, Lisa A.; McDaniel, Mark A.; Repice, Michelle; Zhao, Jiuqing; Frey, Regina F. – Physical Review Special Topics - Physics Education Research, 2014
Interactive-engagement (IE) techniques consistently enhance conceptual learning gains relative to traditional-lecture courses, but attitudinal gains typically emerge only in small, inquiry-based curricula. The current study evaluated whether a "scalable IE" curriculum--a curriculum used in a large course (~130 students per section) and…

McQueen, H. A.; Shields, C.; Finnegan, D. J.; Higham, J.; Simmen, M. W. – Biochemistry and Molecular Biology Education, 2014
We demonstrate that student engagement with PeerWise, an online tool that allows students to author and answer multiple-choice questions (MCQs), is associated with enhanced academic performance across diverse assessment types on a second year Genetics course. Benefits were consistent over three course deliveries, with differential benefits…

Witzig, Stephen B.; Rebello, Carina M.; Siegel, Marcelle A.; Freyermuth, Sharyn K.; Izci, Kemal; McClure, Bruce – Research in Science Education, 2014
Identifying students' conceptual scientific understanding is difficult if the appropriate tools are not available for educators. Concept inventories have become a popular tool to assess student understanding; however, traditionally, they are multiple choice tests. International science education standard documents advocate that assessments…
