Enhanced Science Education Through the Use of Modern FTNMR Spectroscopy

该项目将通过创新使用惠特沃斯学院的傅里叶变换核磁共振光谱仪来加强科学教育。教育专业学生和低年级理科学生将通过亲身体验这一强大的技术来更具体地掌握化学原理。更复杂的实验也将由化学专业的学生进行。该提案的一个独特之处是强调理科教师和教育教师之间的合作努力。未来的K-12教师和其他化学背景相对有限的学生将进行适合他们水平的核磁共振实验室练习。在这些实验中，学生将识别共同的化学结构，并通过使用FINMR跟踪代谢途径的过程。K-12教师将在由惠特沃斯教师在科学和教育部门联合举办的暑期研讨会上进行类似的实验。研讨会的参与者将被鼓励把他们的学生带回校园，进行“实验室实地考察”，重点是核磁共振光谱仪，它将位于新改建的埃里克·约翰斯顿科学中心的显眼位置。化学专业的学生也将从该项目中受益匪浅。这些学生将在他们的第一堂实验室课程中被介绍光谱仪的实际使用。他们将使用光谱仪来识别少量产生的反应产物，并监测化学反应的过程。高年级化学学生将获得必要的背景知识，开展更多的活动。复杂的实验。他们将鉴定配位络合物的立体异构体，分析酶催化反应的复杂性，并利用多脉冲LD和2D核磁共振技术来确定单萜的结构。最后，光谱仪还将刺激教师指导的本科生研究项目。

This project will enhance science education through innovative use of an FTNMR Spectrometer at Whitworth College. Education students and lower division science students will be enabled to more concretely grasp chemical principles through hands-on experience with this powerful technique. More sophisticated experiments will also be carried out by chemistry majors. A unique feature of the proposal is the emphasis on collaborative efforts between science faculty and education faculty. Prospective K-12 teachers and other students with relatively limited chemistry background will carry out NMR laboratory exercises geared to their level. In these experiments, students will identify common chemical structures and follow the course of a metabolic pathway through the use of FINMR. K-12 teachers will carry out similar experiments in summer workshops hosted jointly by Whitworth faculty in the science and education departments. Participants in the workshops will be encouraged to bring their students back to the campus for "laboratory field trips" focused on the NMR spectrometer which will be located prominantly within the newly remodeled Eric Johnston Science Center. Chemistry students will also benefit tremendously from the project. These students will be introduced to practical use of the spectrometer in their very first laboratory courses. They will use the spectrometer to identify reaction products generated in small quantities and to monitor the course of chemical reactions. Upper division chemistry students will gain the background necessary to carry out more. sophisticated experiments. They will identify stereoisomers of a coordination complex, analyze the intricacies of an enzyme-catalyzed reaction, and utilize multi-pulse lD and 2D NMR techniques to determine the structures of monoterpenes. Finally, the spectrometer will also stimulate faculty- directed undergraduate research projects.
