W48: Open-Ended Technique Labs in Introductory Courses

Alicia A. Peterson, College of Saint Benedict
Edward J. McIntee, College of Saint Benedict

In an NSF-funded revision of the first year laboratory sequence at the College of Saint Benedict/Saint John’s University, students develop practical skills in the laboratory to prepare them so that they are able to carry out tasks that chemists routinely do in research projects, such as purify and identify compounds.  The first semester course (Purification 1) focuses on methods such as distillation, filtration and extraction, whereas the second semester laboratory (Purification 2) introduces a wide variety of chromatographic techniques.  In small group settings, the workshop leaders will facilitate discussions on how to develop and implement technique-based labs.  In this lab sequence, students must analyze their purified unknowns, primarily using NMR, IR, MS and UV-Vis techniques.  A secondary focus of this workshop will address the methods developed to teach spectroscopy to students who have little background in the structure of compounds or data analysis.  PowerPoint presentations, in-class practice problems and online text resources have been developed for this purpose.  Participants will have an opportunity to actively solve spectral problems as well as explore resources for teaching spectroscopy for first-year students.  Participants will receive a CD with the class materials, lab experiments, instructor notes and unknown mixture combinations; 3-hour session.
