Barcena, Homar; Tuachi, Abraham; Zhang, Yuanzhuo – Journal of Chemical Education, 2017
The synthesis of epoxidized soybean oil (ESO) provides students a vantage point on the application of green chemistry principles in a series of experiments. Qualitative tests review the reactions of alkenes, whereas spectroscopic analyses provide insight in monitoring functional group transformations.

Tyler, Sarah F.; Judkins, Eileen C.; Morozov, Dmitry; Borca, Carlos H.; Slipchenko, Lyudmila V.; McMillin, David R. – Journal of Chemical Education, 2017
Electronic spectra often exhibit vibronic structure when vibrational and electronic transitions occur in concert. Theory reveals (1) that orbital symmetry considerations determine specific roles played by the nuclear degrees of freedom and (2) that the vibrational excitation is often highly regiospecific, that is, attributable to an identifiable…

Kjonaas, Richard A.; Fitch, Richard W.; Noll, Robert J. – Journal of Chemical Education, 2017
A microscale isotopic labeling experiment is described for the introductory organic chemistry laboratory course wherein half of the students use sodium borohydride (NaBH[subscript 4]) and the other half use sodium borodeuteride (NaBD[subscript 4]) to reduce acetophenone to 1-phenylethanol and then compare spectral data. The cost is reasonable, and…

Fry, Charles G.; Hofstetter, Heike; Bowman, Matthew D. – Journal of Chemical Education, 2017
Quantitative [superscript 13]C NMR provides a straightforward method of analyzing edible oils in undergraduate chemistry laboratories. [superscript 13]C spectra are relatively easy to understand, and are much simpler to analyze and workup than corresponding [superscript 1]H spectra. Average chain length, degree of saturation, and average…

Sosabowski, Michael Hal; Olivier, George W. J.; Jawad, Hala; Maatta, Sieja – School Science Review, 2017
Natural products are ubiquitous in nature but do not form a large proportion of the A-level syllabuses in the UK. In this article we briefly discuss a small selection of natural products, focusing on alcohols, aldehydes and ketones, and alkaloids. We then outline two natural product experiments that are suitable for A-level chemistry clubs or…

Gaquere-Parker, Anne C.; Hill, Patricia S.; Haaf, Michael P.; Parker, Cass D.; Doles, N. Allie; Yi, Amanda K.; Kaminski, Todd A. – Journal of Chemical Education, 2017
Generating enthusiasm among nonscience majors in a laboratory course is a difficult task. Often, students are asked to perform a precipitation reaction, only to collect and then safely dispose of the solid without detailing composition, properties, or uses. In an effort to keep the students engaged, this laboratory exercise presents an innovative…

Johnstone, Erik V.; Yates, Mary Anne; Poineau, Frederic; Sattelberger, Alfred P.; Czerwinski, Kenneth R. – Journal of Chemical Education, 2017
The radioactive nature of technetium is discussed using a combination of introductory nuclear physics concepts and empirical trends observed in the chart of the nuclides and the periodic table of the elements. Trends such as the enhanced stability of nucleon pairs, magic numbers, and Mattauch's rule are described. The concepts of nuclear binding…

Venkataraman, Bhawani – Journal of Chemical Education, 2017
This paper describes a pedagogical approach to help students understand chemical bonding by emphasizing the importance of electrostatic interactions between atoms. The approach draws on prior studies that have indicated many misconceptions among students in understanding the nature of the chemical bond and energetics associated with bond formation…

Alpaydin, Sabri – Online Submission, 2017
This study was carried out to determine the level of understanding and misconceptions of science teacher candidates about some concepts related to material and its properties. This research was carried out with 260 science teacher candidates in Science Teaching Education Program of Education Faculty of Necmettin Erbakan University in 2015-2016…

Lewis, Elizabeth B.; Rivero, Ana M.; Lucas, Lyrica L.; Musson, Aaron A.; Helding, Brandon A. – Journal of Research in Science Teaching, 2021
In the United States, research on beginning science teachers provides little guidance regarding empirical minimum levels of discipline-specific science coursework for sufficient subject matter knowledge to teach science. Accordingly, in this study we analyzed secondary physical science teachers' science coursework for subject matter knowledge…

Orozco, Mariana; Gijbels, David; Timmerman, Christiane – Journal of Vocational Education and Training, 2021
The integration of theory and practice constitutes an anchor of today's technical vocational education and training (T-VET) and a major determinant of professional development. Understanding such integration is expected to contribute to pedagogical advancement and to provide new research tools. Current knowledge on the epistemological roots of…

Moreno, Candido; Pham, Duyen; Ye, Li – Chemistry Education Research and Practice, 2021
Chemistry self-efficacy (CSE) was identified as a critical affective construct to predict student success in chemistry classrooms. We surveyed students at the beginning and toward the end of a semester to measure students' CSE beliefs in introductory and general chemistry courses at a Hispanic-serving institution in the United States. First, the…

Davy, Emma C.; Quane, Steven L. – Journal of Chemical Education, 2021
Lab-based learning is an essential part of any undergraduate chemistry curriculum as it incorporates necessary and required hands-on experiential learning. However, in response to the COVID-19 pandemic, many students are learning from home, rendering laboratory instruction a particular challenge. Options for educators include third party virtual…

Santyasa, I. Wayan; Agustini, Ketut; Pratiwi, Ni Wayan Eka – International Journal of Instruction, 2021
Chemistry learning in high school should encourage the application of knowledge learned to solve real-world problems around students without delay. This study aimed at analyzing the effect of the project based e-learning model (PjBeL) compared to direct e-learning (DeL) and academic procrastination (AP) on students' critical thinking skills and…

Vyas, Vijay S.; Kemp, Benedict; Reid, Scott A. – International Journal of Science Education, 2021
General chemistry are key gateway courses for many Science, Technology, Engineering, and Mathematics (STEM) majors. To improve student outcomes, it is critical both to identify at-risk students and implement evidence-based instructional strategies and interventions. These remain active areas of investigation, with recent literature showing that…
