Collaborative Enhancement of Science Education with Inquiry-Based GCMS Experiments

化学（12）。 这个合作项目是使用GC/MS仪器的收购开发基于项目的实验室实验，使用引导探究学习经验，整合研究和教育，以及提供跨学科的应用。这些实验的重点是：（1）鉴定柑橘（葡萄柚）中有气味的有机硫化合物;（2）分析葡萄酒，香水和香料的挥发性成分;（3）定量测定尿液中的乳清酸;和（4）与Bignonia capreolata（路易斯安那州杂交葡萄）气味成分相关的跨学科实验。 实验室经验包括参与研究项目，如：（a）锡布利湖有机化合物的GC/MS测定（邻近NSU）作为监测北方路易斯安那州湖泊地表水质量的更广泛项目的一部分;（B）路易斯安那州杂交藤气味的调查包括研究哪些成分吸引哪些传粉者和其他跨学科的实地研究;和（c）尿液中乳清酸的定量测定是GC/MS在临床化学中应用的更广泛研究的一部分。 该项目更广泛的影响包括科学专业，非科学专业和K-12学生的研究和教育的整合。 该项目还通过提供现代科学仪器来促进路易斯安那州北方几个学生人数不足的机构之间的研究和教育合作，从而加强了研究和教育的基础设施。 评估和传播计划提供了一个模型，说明如何使用引导式查询，研究经验和协作来增强当前和未来STEM教育工作者，专业人员和学生的大型和多样化群体的STEM技能。

Chemistry (12). This collaborative project is using the acquisition of a GC/MS instrument to develop project-based laboratory experiments that use guided-inquiry learning experiences to integrate research and education as well as to provide interdisciplinary applications. The experiments are focusing on: (1) the identification of odoriferous organosulfur compounds in Citrus paradisi (grapefruit); (2) the analysis of volatile components of wines, perfumes, and spices; (3) the quantitative determination of orotic acid in urine; and (4) an interdisciplinary experiment relating the odor constituents of Bignonia capreolata (Louisiana crossvine). The laboratory experiences include participating in research projects such as: (a) the GC/MS determination of organic compounds in Sibley Lake (adjacent to NSU) as part of a broader project to monitor surface water quality in northern Louisiana lakes; (b) the investigation of Louisiana crossvine scent includes research into which constituents attract which pollinators and other interdisciplinary field studies; and (c) the quantitative determination of orotic acid in urine is part of a broader investigation of GC/MS applications in clinical chemistry. The broader impact of the project includes the integration of research and education for science majors, non-science majors, and K-12 students. The project also enhances the infrastructure for research and education by providing modern scientific instrumentation to stimulate research and educational collaborations among several institutions in northern Louisiana that have significant numbers of underrepresented students. The evaluation and dissemination plan is providing a model for how guided inquiry, research experiences, and collaboration can be used to augment the STEM skills in a large and diverse group of current and future STEM educators, professionals, and students.
