Improving Undergraduate Learning Across the Chemistry Curriculum through Integration of GC-MS

通过在整个化学课程和生物和地球科学课程中整合先进的气相色谱和质谱仪(GC-MS)检测，学生对复杂环境问题的理解正在扩大。一种螺旋式的方法，从普通化学开始，在整个课程中继续以指导性探究和基于项目的实验室经验为基础，利用这种强大的连接技术来培养学生的专业知识，以解决重要的问题。主题和实验是根据化学和研究文献改编和实施的，包括GC-MS的多种用途。GC-MS还被用于跨学科领域(生态学和地球科学)，以加强现有的合作，鼓励更多的合作，并说明科学研究的跨学科性质。

Through integration of advanced gas chromatography with mass spectrometry (GC-MS) detection across the chemistry curriculum and into the biology and geoscience curriculum, student understanding of complex environmental issues is being expanded. A spiraled approach starting in General Chemistry and continuing with guided-inquiry, project-based laboratory experiences throughout the curriculum is developing student expertise using this powerful hyphenated technology toward solving important issues. The topics and the experiments are being adapted and implemented from the chemical and research literature and include multiple uses for the GC-MS. The GC-MS is also being used across discipline lines (ecology and geoscience) to strengthen existing collaborations and to encourage additional ones and to illustrate the interdisciplinary nature of scientific inquiry.
