Enhancing Student Learning by Incorporating NMR Spectroscopy into the General and Organic Chemistry Curriculum

化学(12)这个项目为学生在新的化学课程中使用现代核磁共振技术，包括基本的和二维的核磁共振技术，提供了越来越深入的实践经验。几个核磁共振实验改编自最近的化学教育文献。有机实验室课程中的几个扩展实验也利用了FT-核磁共振。普通化学学生在几个涉及化合物鉴定的入门实验中使用1H和质子去耦合的13C核磁共振。有机化学专业学生在有机合成中使用~1H、~(13)C、DEPT和2D-核磁共振技术(COSY和HETCOR)进行结构测定和产物鉴定。拟议课程的一个突出特点是在实验中广泛纳入分子建模，以将计算实验与实验结果联系起来。其他部分旨在：(1)为当地高中教师和学生开发一个为期三周的核磁共振研讨会，以促进人们对科学的兴趣；以及(2)让一些一年级和二年级的理科专业学生与邻近的四年制院校进行研究合作。设计了一项全面的评估计划，以评估该项目的总体影响，评估其具体的教学目标和目的，并在课程中实施适应的实验时衡量学生的学习情况。作为这一项目的结果，完成新课程的学生将在转到四年制院校后为技术工作或高级实验室和研究做好准备。

Chemistry (12)This project provides students with an increasingly in-depth, hands-on experience in the use of modern NMR, including basic and 2-D NMR techniques as they progress through the new chemistry curriculum. Several NMR experiments are adapted from recent chemical education literature. Several expanded experiments in the Organic laboratory curriculum also utilize the FT-NMR. General chemistry students use 1H and proton-decoupled 13C NMR in several introductory experiments involving compound identification. Organic chemistry students use 1H, 13C, DEPT and 2D-NMR techniques (COSY and HETCOR) in structure determination and product identification in organic syntheses. A prominent feature of the proposed curriculum is the extensive incorporation of molecular modeling in the experiments to connect computational experiments to experimental results. Additional components are designed to: (1) develop a three-week NMR workshop for local high school teachers and students to promote interest in science, and (2) involve a number of freshman and sophomore science majors in research collaboration with neighboring four-year institutions. A comprehensive evaluation plan is designed to assess the overall impact of the project, evaluate its specific pedagogical goals and objectives, and measure student learning as the adapted experiments are implemented in the curriculum. As a result of this project, students completing the new curriculum will be well prepared for either technical employment or upper-level laboratories and research after transferring to four-year institutions.
