Recent research has shown that a large class of genes code for the receptor sites in our olfactory system. This module for general chemistry emphasizes the importance of a molecular-based understanding of biological systems as students learn to propose and test increasingly complex models to account for the ability to detect and discriminate odors. Consequently, students are confronted with a "need-to-know" concepts such as molecular formulas, valence electrons, Lewis dot structures, functional groups, VSEPR, stereochemistry, and the "lock and key" model. Propagation of messages form the nose to the brain by neurotransmitters are also studied in order to explore further the issue of the chemical basis
of life. This presentation will describe how the "need-to-know" is developed amongst students as well as the sequencing of lab and lecture activities. Audience members will have the opportunity to participate in some "nose-on" activities.
Stacey Lowery Bretz is an Associate Professor of Chemistry at Youngstown State University in Youngstown, OH. Dr. Bretz earned her B.A. and M.S. in chemistry at Cornell University and Penn State University, respectively, before returning to Cornell to pursue a Ph.D. in chemistry education with Joseph Novak, Roald Hoffmann, and Jerrold Meinwald. After completing her Ph.D., Dr. Bretz moved to U.C. Berkeley to do a post-doc with Angelica Stacy and be Director of Evaluation and Assessment for the ModularChem Consortium systemic initiative. For five years, Dr. Bretz was on the faculty at University of Michigan-Dearborn until she was lured away this past year to join YSU, where her responsibilities include designing an M.S. program in chemistry education and serving as director for CATALYST (Center for Advancement of Teaching and Learning at Youngstown State). Dr. Bretz's research, which focuses on the application of theories from the field of cognitive science to both the teaching and learning of chemistry, also includes strong interests in assessment of student learning and qualitative methodologies for program evaluation.
