The quality of undergraduate education in the scientific process has been enhanced through the acquisition of routine gas chromatograph/mass spectrometers for use in courses which service chemistry majors, premedical students and non-science majors. The primary us of the instrumentation is in the two semester organic chemistry course. Instead of first learning reaction details in lecture with subsequent verification in the laboratory, students are first guided to predict major reaction products (often based on results from molecular mechanics calculations), conduct the reaction (representative of that introduced in lecture without mechanistic detail) and observe trends in product formation. In most instances, each student executes experiments under slightly different conditions; the class results are pooled and displayed with a computer projection system by the instructor. Students participate as a group in the analysis and discussion of their results to formulate and test plausible mechanisms. Utilization of instrumentation in this "discovery" approach promotes true student involvement in the study of organic chemistry, increases interest in the discipline and thus betters chances of attracting and retaining chemistry majors. The school contributed to this project in an amount equal to the NSF funds.

通过购买常规气相色谱仪/质谱仪，提高了科学过程本科教育的质量，用于为化学专业、医学预科学生和非科学专业学生提供服务的课程。该仪器的主要用途是在两个学期的有机化学课程中。不是先在课堂上学习反应细节，然后在实验室进行验证，而是首先引导学生预测主要的反应产物（通常基于分子力学计算的结果），进行反应（代表课堂上介绍的反应，没有力学细节），观察产物形成的趋势。在大多数情况下，每个学生在略有不同的条件下进行实验；课堂成绩由讲师汇总并在计算机投影系统上显示。学生作为一个小组参与分析和讨论他们的结果，以制定和测试合理的机制。在这种“发现”方法中使用仪器可以促进学生真正参与有机化学的研究，增加对这门学科的兴趣，从而更好地吸引和留住化学专业的学生。学校为这个项目提供了相当于NSF基金的资金。
