Enhancing the Chemistry Curriculum with FT-NMR Spectroscopy

马里兰圣玛丽学院化学系正在开发一种更加以学习者为中心的课程，该课程由适当的教学实践和技术工具提供支持。从研究和教育文献中改编的基于探究的实验室经验被视为这一努力的基本要素。该系已购买了一台300兆赫FT-NMR光谱仪，用于支持该系正在进行的将探究式实验室工作纳入化学课程的努力。随着FT-NMR的使用，额外的实验正在加强已经引入探究方法的课程，并允许将探究活动纳入额外的课程。普通化学课程中的探究式实验正在被修改，以包括使用FT-NMR对原子结构的探索。使用FT-NMR的探究活动也被引入到有机、无机和高级光谱学课程中。学生们正在将常规的FT-NMR用于实验室合成产品的表征。在随后的课程中，他们使用了复杂的技术，如COSY， DEPT， HETCOR和脉冲序列。作为毕业要求，所有学生现在都需要完成一个为期一年的学生研究项目，圣玛丽项目。FT-NMR对许多学生在探索化学结构和反应性的各个方面时特别有用。

Chemistry (12)The Department of Chemistry at St. Mary's College of Maryland is developing a more learner-centered curriculum that is supported by appropriate pedagogical practices and technological tools. Inquiry-based laboratory experiences adapted from both the research and educational literature are viewed as an essential element of this effort. The department has purchased a 300 MHz FT-NMR spectrometer that is being used to support the departments on-going efforts to incorporate inquiry-based laboratory work into the chemistry curriculum. With access to the FT-NMR, additional experiments are enhancing courses where inquiry methods have already been introduced and are allowing the incorporation of inquiry activities into additional courses. The set of inquiry-based experiments in the General Chemistry courses are being modified to include an exploration of atomic structure using the FT-NMR. Inquiry activities using the FT-NMR are also being introduced in the organic, inorganic, and advanced spectroscopy courses. Students are incorporating the use of routine FT-NMR for the characterization of products synthesized in their laboratory work. In subsequent courses, they are using sophisticated techniques such as COSY, DEPT, HETCOR and pulse sequences. As a graduation requirement, all students are now required to complete a year-long student research project, the St. Mary's Project. The FT-NMR is especially useful to many students as they explore various aspects of chemical structure and reactivity.
