Integration of Gas Chromatography Mass Spectrometry and Fourier Transform Infrared Spectroscopy into the Undergraduate Curriculum

化学（12）通过引入强调批判性思维和用现实问题挑战学生的基于情境的实验，化学实验课程正在被改造和振兴。学生也可获得服务学习的机会。通过这些活动，学生们了解了化学在我们社会中的作用，特别是在解决环境问题、现代仪器和技术的能力和局限性以及与社区建立联系方面。这些实验室经验改编自教育和研究文献，部分通过使用气相色谱-质谱联用仪（GC-MS）和傅里叶变换红外（FT-IR）分光光度计实施。来自低年级和高年级实验室课程的学生团队，包括环境、分析、仪器、有机化学和物理科学，为职前教师提供服务，他们正在调查与保护和维持附近美国原住民保留区自然资源有关的环境问题。由于以探究为基础的实验室及其服务学习的组成部分，学生们将重点放在科学过程和结果的意义上，而不是遵循烹饪书式的实验。

Chemistry (12)The chemistry laboratory curriculum is being transformed and revitalized by the introduction of context-based experiments that emphasize critical thinking and that challenge students with real-world problems. Students are also being provided with service learning opportunities. From these activities, the students are understanding the role of chemistry in our society, particularly toward solving environmental issues, the capabilities and limitations of modern instrumentation and technology, and building connections with their community. These laboratory experiences are being adapted from the educational and research literature and are being implemented in part through the use of a Gas Chromatograph-Mass Spectrometer (GC-MS) and a Fourier Transform Infrared (FT-IR) spectrophotometer. Teams of students from lower and upper division laboratory courses including Environmental, Analytical, Instrumental, and Organic Chemistry and Physical Science for pre-service teachers are investigating environmental issues related to protecting and sustaining natural resources on a nearby Native American Reservation. As a consequence of the inquiry-based laboratories and their service-learning component, students are focussing on the scientific process and the significance of results, rather than following cookbook-type experiments.
