Introduction of Mass Spectrometry to the Chemistry Curriculum of the Chicago-area Community Colleges

化学（12）芝加哥地区十所社区学院（CC）的化学专业学生正在学习使用伊利诺伊州芝加哥洛约拉大学提供的GC/MS和LC/MS仪器进行环境质谱分析。学生通过远程互联网接入获取和分析质谱数据。这三个环境分析实验的设计是为了让初学化学的学生很容易掌握它们的目的和终点。CC学生接触到现代分析方法和仪器来解决重要的问题，这将鼓励这些学生对化学产生更大的兴趣，并鼓励他们更多地攻读化学学士学位。学生们正在分析氯和溴化有机分子，它们是水消毒过程的副产品。选择这些实验是因为它们是向那些有机化学背景可能有限的学生教授基本质谱解释的良好工具。这些实验室的另一个目标是让CC学生熟悉不同类型的质谱实验，特别是那些用于确定经验公式和/或化合物身份的实验，而不是用于量化目标分析物的实验。6位参与的芝加哥CC教授（3位共同pi和3位其他参与者）正在参加由仪器制造商在洛约拉大学举办的GC/MS和LC/MS仪器使用培训研讨会。CC教授被鼓励参与在线演示，并创建教育模块，这些模块可能被纳入实验室间网络（ILN），作为本工作传播的一部分。该评估计划评估使用基于互联网的技术接触环境质谱的学生是否比没有接触环境质谱的学生更有可能进入四年制大学并完成学士学位。该计划还衡量了学生对化学职业的看法，以及对环境问题的兴趣是否会激励学生从事化学职业。正在将评估工具纳入在线访问，以促进信息的收集。该项目的研究结果将在两年一次的化学教育会议和美国化学学会会议上发表。该计划与美国国家科学基金会加强教育机构的网络基础设施，以促进网上资源共享的倡议一致。

Chemistry (12)Chemistry students in the ten Chicago area community colleges (CC) are being introduced to environmental mass spectrometry analyses using the GC/MS and LC/MS instrumentation available at Loyola University in Chicago, IL. Students acquire and analyze mass spectrometry data through remote internet access. The three environmental analysis experiments are designed so that their purpose and endpoints are easy for beginning chemistry students to grasp. The exposure of CC students to modern analytical methods and instrumentation applied to solving problems whose importance is compelling is expected to encourage more interest in chemistry among those students and to encourage more of them to pursue a bachelor's degree in chemistry. Students are analyzing chlorinated and brominated organic molecules that are by-products of the water disinfection process. These experiments were chosen because they are good vehicles for teaching basic mass spectrometry interpretation to students whose background in organic chemistry is likely to be limited. Another goal of these laboratories is to acquaint the CC students with different types of mass spectrometry experiments, in particular those that are used to determine the empirical formula and/or identity of a compound versus experiments that are used to quantify targeted analytes. The six participating Chicago CC professors (3 co-PIs and 3 other participants) are attending training seminars for the use of the GC/MS and LC/MS instruments, conducted by the instrument manufacturer at Loyola University. The CC professors are encouraged to participate in online demonstrations and to create educational modules that may be incorporated into the InterLaboratory Network (ILN) as part of the dissemination of this work. The assessment plan evaluates whether students who are exposed to environmental mass spectrometry using internet-based technologies are more likely to go on to a 4-year institution and complete a bachelor's degree than students who do not take part. The plan also measures student perceptions of careers in chemistry and whether interest in environmental issues motivates students to pursue a career in chemistry. The assessment tools are being incorporated into the online access to facilitate gathering of information. Results of this project will be presented at the Biennial Conference on Chemical Education and at American Chemical Society meetings. This project aligns with the NSF initiative to enhance the cyberinfrastructure of educational institutions to promote the sharing of online resources.
