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挑战学生现实世界问题的基于情境的实验，化学实验室的课程正在被改造和振兴。此外，还为学生提供服务性学习机会。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他们的社区建立联系方面。这些实验室经验改编自教育和研究文献，并部分通过使用气相色谱-质谱仪(GC-MS)和傅立叶变换红外(FT-IR)分光光度计来实施。来自下级和上级实验室课程的学生团队正在调查与保护和维持附近美洲原住民保护区的自然资源相关的环境问题，这些课程包括为职前教师开设的环境化学和物理科学课程。作为探究式实验室及其服务学习部分的结果，学生们正专注于科学过程和结果的意义，而不是遵循食谱类型的实验。

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.
