Croisant, Michael; Bretz, Stacey Lowery; Konkolewicz, Dominik – Journal of Chemical Education, 2019
The ACS Guidelines for bachelor's degrees in chemistry call for the curriculum to include polymer chemistry principles and the synthesis of different classes of macromolecules. Organic chemistry can provide an important introduction to polymer chemistry principles, and photochemically induced radical polymerization is one method for generating…

Popova, Maia; Bretz, Stacey Lowery; Hartley, C. Scott – Journal of Chemical Education, 2016
Although stereochemistry is an important topic in second-year undergraduate organic chemistry, there are limited options for laboratory activities that allow direct visualization of macroscopic chiral phenomena. A novel, guided-inquiry experiment was developed that allows students to explore chirality in the context of cholesteric liquid crystals.…

Galloway, Kelli R.; Malakpa, Zoebedeh; Bretz, Stacey Lowery – Journal of Chemical Education, 2016
Meaningful learning requires the integration of cognitive and affective learning with the psychomotor, i.e., hands-on learning. The undergraduate chemistry laboratory is an ideal place for meaningful learning to occur. However, accurately characterizing students' affective experiences in the chemistry laboratory can be a very difficult task. While…

Bindis, Michael P.; Bretz, Stacey Lowery; Danielson, Neil D. – Journal of Chemical Education, 2011
The high-performance liquid chromatography (HPLC) experiment, most often done in the undergraduate analytical instrumentation laboratory course, generally illustrates reversed-phase chromatography using a commercial C[subscript]18 silica column. To avoid the expense of periodic column replacement and introduce a choice of columns with different…

Hohloch, Janice M.; Grove, Nathaniel; Bretz, Stacey Lowery – Journal of Chemical Education, 2007
A pre-service science and mathematics teacher participated in an action research project to reform a chemistry course required of elementary and middle childhood pre-service teachers. Activities to emphasize a hands-on approach to learning chemistry and to model teaching science through inquiry for these pre-service teachers are described. The…

Grove, Nathaniel; Bretz, Stacey Lowery – Journal of Chemical Education, 2005
An inquiry-based experiment on Sherlock Holmes adventure stories used to actively involve students in a series of laboratory experiments to prove the guilt of the accused murderer is presented. The result from such experiments showed that students were able to distinguish between sugar and possible poison.
