The work describes an analogy-based small oscillations analysis of a standard static equilibrium lab problem. In addition to force analysis, a potential energy function for the system is developed, and by drawing out mathematical similarities to the simple harmonic oscillator, we are able to describe (and experimentally verify) the period of small…

Stephens, Jessica D.; Battle, David C.; Gormally, Cara L.; Brickman, Peggy – Journal of College Science Teaching, 2017
Early training opportunities for future faculty, namely graduate students and postdoctoral researchers, can better prepare them to use active learning approaches. We know that instructional feedback supports sustained change and motivates instructors to improve teaching practices. Here, we incorporate feedback as a key component of a pedagogical…

Fonseca, Custódia S. C. – Journal of Chemical Education, 2017
Sigmatropic rearrangement is one of the main classes of pericyclic reactions, which does not necessarily mean that these rearrangements have a pericyclic mechanism. The allylic saccharin derivative O-cinnamylsaccharin can isomerize into N-cinnamylsaccharin in the polar solvent system toluene/triethylamine in a reaction time of 2 h at 110°C. The…

Richard, Melissa; Coley, John D.; Tanner, Kimberly D. – CBE - Life Sciences Education, 2017
Natural selection is a central concept throughout biology; however, it is a process frequently misunderstood. Bacterial resistance to antibiotic medications provides a contextual example of the relevance of evolutionary theory and is also commonly misunderstood. While research has shed light on student misconceptions of natural selection, minimal…

McCullagh, James V.; Hirakis, Sophia P. – Journal of Chemical Education, 2017
This synthesis of ethyl 6-acetoxyhexanoate (Berryflor) is designed as an experiment for use in a second-year organic chemistry course focusing on the synthesis and reaction of esters. The compound is described as having a raspberry-like odor with jasmine and anise aspects. A two-step procedure for its synthesis beginning with inexpensive…

Modir, Bahar; Thompson, John D.; Sayre, Eleanor C. – Physical Review Physics Education Research, 2017
Students' difficulties in quantum mechanics may be the result of unproductive framing and not a fundamental inability to solve the problems or misconceptions about physics content. We observed groups of students solving quantum mechanics problems in an upper-division physics course. Using the lens of epistemological framing, we investigated four…

Zhang, Lili; Zhang, Wei; Wu, Chong; Liu, Zhongming; Cai, Yunfei; Cao, Xingguo; He, Yushan; Liu, Guoxiang; Miao, Hongming – Biochemistry and Molecular Biology Education, 2017
The effect of scientific training on course learning in undergraduates is still controversial. In this study, we investigated the academic performance of undergraduate students with and without scientific training. The results show that scientific training improves students' test scores in general medical courses, such as biochemistry and…

In scientific and technical degrees, the opinion of the final employers on the given subjects is really important. For this reason, the Quality Committee (CQ) of the Faculty of Chemistry of the University of Barcelona prepared a survey for chemical, engineering and pharmaceutical companies asking about the academic training required by the…

French, Debbie A.; Burrows, Andrea C. – Journal of College Science Teaching, 2017
Increases in student-centered pedagogy have been more prevalent in K-12 education than in collegiate undergraduate science education. The purpose of this study was to determine the effects of using student-centered pedagogy advocated in K-12 education on introductory astronomy students' content knowledge, interest, and recall of content taught in…

Tavares, Maurício T.; Primi, Marina C.; Silva, Nuno A. T. F.; Carvalho, Camila F.; Cunha, Micael R.; Parise-Filho, Roberto – Journal of Chemical Education, 2017
Teaching the molecular aspects of drug-target interactions and selectivity is not always an easy task. In this context, the use of alternative and engaging approaches could help pharmacy and chemistry students better understand this important topic of medicinal chemistry. Herein a 4 h practical exercise that uses freely available software as a…

Chiu, Yu-Chun; Jenks, Matthew A.; Richards-Babb, Michelle; Ratclif, Betsy B.; Juvik, John A.; Ku, Kang-Mo – Journal of Chemical Education, 2017
We report here the development of an inexpensive and engaging laboratory-based activity that can help students learn about the scientific method and the role of plant epicuticular waxes and surfactant function on waxy plant leaves as real life example in the agricultural industry. Three each of nontreated collard leaves ("Brassica…

Marušic, Mirko; Sliško, Josip – European Journal of Physics Education, 2017
In this research, we gave to technical university students (N=50) and high school students (N=75) a verbally described situation of a partially defined physics problem. The task for the both groups of the students was to generate drawings of how they imagined the situation that the problem referred to. A fully abstract drawing was generated by 48%…

Kempton, Colton E. – ProQuest LLC, 2017
Eukaryotes use proteins to carefully package and compact their genomes to fit into the nuclei of their individual cells. Nucleosomes are the primary level of compaction. Nucleosomes are formed when DNA wraps around an octamer of histone proteins and a nucleosome's position can limit access to genetic regulatory elements. Therefore, nucleosomes…

Dai, Ting; Kaplan, Avi; Wing, Ying; Cromley, Jennifer G.; Perez, Tony; Mara, Kyle R.; Balsai, Kyle R.; Yo – AERA Online Paper Repository, 2017
Whereas relevance-writing interventions have shown effects on students' achievement, a persistent finding is that interventions benefit students with low, but not high, outcome expectancies--a phenomenon that Schwartz et al. (2016) termed the half empty question. In the current mixed-methods study, we investigated the role of undergraduate…

Pérez-Álvarez, Leyre; Ruiz-Rubio, Leire; Vilas-Vilela, Jose Luis – Journal of Chemical Education, 2018
To enhance critical thinking and problem-solving skills, a project-based learning (PBL) approach for "Instrumental Techniques" courses in undergraduate physical chemistry was specifically developed for a pharmacy bachelor degree program. The starting point of this PBL was an open-ended question that is close to the student scientist's…
