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

化学(12)这个项目的目标是增加学生从化学入门到更高级的课程和从事科学职业的比例。我们正在改变学生对化学实验室的看法，通过增加以项目为导向的实验，使用先进的GC和GCMS仪器来解决主题和相关问题，从而实现这一点。第二个目标是通过提供更类似于他们在工作场所的实验室体验来加强我们的学生的准备。使用四台岛津GC-14B系列毛细管气相色谱仪和配备自动进样器的QP-5000 GCMS系统整合到一系列实验的课程中，支持了将FTIR、UV/Vis、GC和HPLC技术引入较低级别实验室的更广泛的部门计划。学生通过反复接触普通化学、有机化学和分析化学的五个实验室部分的GC和GCMS仪器，逐步培养他们的技能。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，以适应我们现有的计划。在实现我们的目标方面，成功与否既通过数字来评估，通过跟踪进入我们普通化学课程的每一名学生的命运来评估，更通过我们现有的系评估计划进行定性评估。除了与其他学院的同事进行非正式讨论外，结果还将在美国化学学会、本科生研究委员会和Sigma Xi的全国会议上与教育界分享。为支持我们的使命而开发的新颖或大幅修订的实验将在《化学教育杂志》上发表，这将完成我们的传播努力。

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.
