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.

化学（12）随着学生在新化学课程中的学习，本项目将为学生提供越来越深入的现代核磁共振应用实践经验，包括基础核磁共振和二维核磁共振技术。几个核磁共振实验改编自最近的化学教育文献。有机实验课程中的几个扩展实验也使用了傅里叶变换核磁共振。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和质子解耦的13C核磁共振。有机化学学生使用1H， 13C， DEPT和2D-NMR技术（COSY和HETCOR）在有机合成中的结构测定和产品鉴定。本课程的一个突出特点是在实验中广泛结合分子建模，将计算实验与实验结果联系起来。额外的组成部分旨在：(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，以促进对科学的兴趣；(2)让一些大一和大二的科学专业学生与邻近的四年制大学进行研究合作。综合评估计划旨在评估项目的整体影响，评估其具体的教学目标和目的，并在课程中实施适应性实验时衡量学生的学习情况。由于这个项目，完成新课程的学生将在转到四年制大学后为技术就业或高级实验室和研究做好充分准备。
