Blurring the Line Between the Teaching and Research Laboratory - Capillary Gas Chromatography and GC/MS Experiments in First and Second Year Chemistry Laboratories

这个项目的目标是增加学生继续从化学入门课程到更高级的课程和从事科学事业的百分比。我们通过增加项目导向实验，使用先进的GC和GCMS仪器来解决主题和相关问题，从而改变学生对化学实验室的看法，从而实现这一目标。第二个目标是通过提供与工作场所更相似的实验室体验来增强学生的准备。将四台岛足GC- 14b系列毛细管气相色谱仪与数据站和配备自动进样器的QP-5000 GCMS系统整合到一系列实验课程中，支持更广泛的部门计划，将FTIR， UV/Vis， GC和HPLC技术引入较低水平的实验室。学生们通过在普通化学、有机化学和分析化学的五个实验室部分中反复接触GC和GCMS仪器，逐渐建立他们的技能。实验是从《化学教育杂志》中精心挑选出来的，并正在进行调整，以适应我们现有的课程。我们通过跟踪每个进入普通化学课程的学生的命运，从数字上评估是否成功实现了我们的目标，并通过我们现有的部门评估计划进行了更定性的评估。研究结果将在美国化学会、本科研究委员会和Sigma Xi的全国会议上与教育界分享，此外还将与其他学院的同事进行非正式讨论。为支持我们的使命而开发的新颖或实质性修订的实验在《化学教育杂志》上的发表将完成我们的传播工作。

Chemistry (12)The goal of this project is to increase the percentage of students continuing from introductory chemistry to more advanced courses and to careers in science. We are accomplishing this by changing students' perceptions of chemistry laboratory through adding project-oriented experiments using advanced GC and GCMS instrumentation to solve topical and relevant problems. A secondary goal is to enhance the preparation of our students by providing laboratory experiences more similar to those they will experience in the workplace. The integration into the curriculum of a series of experiments using four Shimadzu GC-14B series capillary gas chromatographs with data stations and a QP-5000 GCMS system equipped with autosampler supports a broader departmental plan to introduce FTIR, UV/Vis, GC, and HPLC techniques into lower level laboratories. Students are gradually building their skills by repeated exposure to the GC and GCMS instruments in each of five laboratory sections accompanying general, organic, and analytical chemistry. Experiments have been carefully selected from the Journal of Chemical Education and are being adapted to fit our existing program. Success in meeting our goals is being assessed both numerically, by tracking the fate of each student entering our general chemistry program, and more qualitatively through our existing departmental assessment plan. Results will be shared with the educational community at national meetings of the American Chemical Society, the Council on Undergraduate Research, and Sigma Xi, in addition to informal discussions with associates at other Colleges. Publication in the Journal of Chemical Education of novel or substantially revised experiments developed to support our mission will complete our dissemination effort.
