Direct linkAbell, Timothy N.; McCarrick, Robert M.; Bretz, Stacey Lowery; Tierney, David L. – Journal of Chemical Education, 2017
A structured inquiry experiment for inorganic synthesis has been developed to introduce undergraduate students to advanced spectroscopic techniques including paramagnetic nuclear magnetic resonance and electron paramagnetic resonance. Students synthesize multiple complexes with unknown first row transition metals and identify the unknown metals by…

Roche Allred, Zahilyn D.; Tai, Heeyoung; Bretz, Stacey Lowery; Page, Richard C. – Biochemistry and Molecular Biology Education, 2017
Students' understandings of foundational concepts such as noncovalent interactions, pH and pK[subscript a] are crucial for success in undergraduate biochemistry courses. We developed a guided-inquiry activity to aid students in making connections between noncovalent interactions and pH/pK[subscript a]. Students explore these concepts by examining…

Galloway, Kelli R.; Bretz, Stacey Lowery – Chemistry Education Research and Practice, 2016
A series of quantitative studies investigated undergraduate students' perceptions of their cognitive and affective learning in the undergraduate chemistry laboratory. To explore these quantitative findings, a qualitative research protocol was developed to characterize student learning in the undergraduate chemistry laboratory. Students (N = 13)…

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.…
