Pan, Yi; Li, Yue Ru; Zhao, Yu; Akins, Daniel L. – Journal of Chemical Education, 2015
A research project for senior undergraduates of chemistry has been developed to introduce syntheses of a series of monodispersed semiconductor PbS quantum dots (QDs) and their characterization methodologies. In this paper, we report the preparation of monodispersed semiconductor PbS QDs with sizes smaller than the exciton Bohr radius using a…

Yu, Hong-Bin – Journal of Chemical Education, 2015
Hiring undergraduate lab assistants in chemistry departments is common in college. However, few studies have focused on promoting undergraduate chemistry learning and thinking skills through this work experience in chemistry teaching laboratories. This article discusses the strategy we implemented in the lab assistant program. The…

Aubrecht, Katherine B.; Padwa, Linda; Shen, Xiaoqi; Bazargan, Gloria – Journal of Chemical Education, 2015
We describe the content and organization of a series of day-long field trips to a university for high school students that connect chemistry content to issues of sustainability. The seven laboratory activities are in the areas of environmental degradation, energy production, and green chemistry. The laboratory procedures have been modified from…

Gao, Ruomei – Journal of Chemical Education, 2015
In a typical chemistry instrumentation laboratory, students learn analytical techniques through a well-developed procedure. Such an approach, however, does not engage students in a creative endeavor. To foster the intrinsic motivation of students' desire to learn, improve their confidence in self-directed learning activities and enhance their…

Thomas, Alyssa C.; Boucher, Michelle A.; Pulliam, Curtis R. – Journal of Chemical Education, 2015
Our Introduction to Research Methods course is a first-year majors course built around the idea of helping students learn to work like chemists, write like chemists, and think like chemists. We have developed this course as a hybrid hands-on/ lecture experience built around instrumentation use and report preparation. We take the product from one…
