Introducing GC/MS into the First-Year General Chemistry Curriculum Using Pattern Recognition and a Verbal Analogy

BNBrian Nowak-ThompsonAshland (United States)

Key Points

To develop an engaging strategy for teaching GC/MS concepts to first-year general chemistry students using pattern recognition techniques.
Introduced GC/MS through pattern recognition using word fragments.
Students compiled mass spectra for unknown words based on their fragments.
Implemented peer comparison of spectra for identifying common words.
Students showed improved understanding of mass spectra concepts.
Peer comparison enhanced collaborative learning and problem-solving skills.

Abstract

AA strategy to introduce GC/MS into the first-year general chemistry curriculum that is based on the idea of pattern recognition is described. Using word fragments, students compile a mass spectrum for their unknown word and then identify others in the class with the same word by comparing spectra. These tasks provide an analogy for the use of mass spectra and database searching as a means to identify organic compounds.
