LC/MS to Enhance Project-Based Laboratories

化学（12）本项目的目标是促进学生对串联色谱-光谱法作为一种利用所有科学共同的方法解决问题的技术的理解，阻止学生对化学思想的划分，促进学生对结构-性质关系的理解，增加学生使用现代仪器的机会，改善教师合作。并在化学课程中加入更多以问题为基础的实验活动。这些目标是通过在化学课程的各个层次的多个课程中实施相同的仪器技术来实现的。因此，多年来，所有化学专业和大多数生物专业的课程都在使用LC/MS，涵盖了化学的几个分支学科。该部门正在使用液相色谱仪/质谱仪来适应和实施最初在杜肯大学开发的示范性实验室经验。改编其他实验室实验和教育文献的项目也正在实施中。这些经过调整的实验和项目将在至少7门基于项目的实验课程中实施，包括有机化学、仪器分析、普通化学、生物化学以及化学和生物学的本科研究。增强的基于项目的实验室正在帮助学生建立跨化学分支学科边界的联系。一旦该项目全面实施，每年将有近200名美利金大学本科生感受到它的影响。

Chemistry (12)The objectives of this project are to promote student understanding of tandem chromatography-spectrometry as a problem-solving technique that takes advantage of methodology common to all sciences, to discourage student compartmentalization of chemical ideas, to facilitate student understanding of structure-property relationships, to increase student access to modern instrumentation, to improve faculty collaboration, and to effect evolution in the chemistry curriculum to include more problem-based laboratory activities. These objectives are being accomplished by implementing the same instrumental technique in multiple courses throughout the strata of the chemistry curriculum. Thus, all chemistry majors and most biology majors are using the LC/MS in courses over multiple years covering several of the sub-disciplines of chemistry.The Department is using the liquid chromatograph/mass spectrometer to adapt and implement exemplary laboratory experiences originally developed at Duquesne University. Adaptation of other laboratory experiments and projects from the educational literature are also being implemented. These adapted experiments and projects are being implemented into at least seven project-based laboratory courses, including Organic Chemistry, Instrumental Analysis, General Chemistry, Biochemistry, and undergraduate research in both Chemistry and Biology. The enhanced project-based laboratories are aiding students make connections across the sub-disciplinary boundaries of chemistry.Once this project is fully implemented, nearly 200 Millikin University undergraduate students will feel its impact each year.
