Stimulating Students' Learning in Analytical Chemistry through an Environmental-Based CURE Project

This article reports on the implementation of a CURE project in an upper-level analytical chemistry course to engage a larger number of students in research at a primarily undergraduate institution (PUI). The lab course syllabus was modified to provide students with an opportunity to experience the process of conducting research through a project that was relevant to them personally and the community at large. Students carried out research using microwave plasma atomic emission spectroscopy (MPAES) to correlate lead levels in soil with home location, source, and age. Students' self-assessment and surveys suggest that implementing a research project that students can relate to leads to an increased level of mastering analytical skills and demonstration of a higher level of critical-thinking skills. Participation in the CURE project increased a desire and a commitment to engage in independent research and in communicating science through presentations.
