This program is updating introductory chemistry curricula by using modern instrumentation in undergraduate courses. The updated curricula are enhancing the quality of introductory chemistry courses, improving the retention of science students, and easing the transition for community college students entering 4-year institutions. Interactive instructional software that provides students and instructors with a "virtual" Fourier-transform infrared (FT-IR) instrument have already been developed. Similar software for a virtual Fourier-transform nuclear-magnetic-resonance (FT-NMR) instrument is currently under development. This software can be used by instructors as a lecture aid for introducing spectroscopic methods and as a tutorial for the use of the FT-IR and FT-NMR instruments. For actual laboratory courses, students can submit samples from their own experiments to regional centers for FT-IR and FT-NMR measurements. Data from each sample are stored on an Internet file server for students to download locally. This file server provides reasonable access to instrumentation, which many community colleges and private colleges typically do not have. By providing students with experience with modern instrumentation and interpretation of their own experimental data, this program is enhancing their understanding of important chemical concepts. In addition, students are gaining insight into the collaborative nature of this scientific process. *

该计划正在更新介绍化学课程，在本科课程中使用现代仪器。 更新后的课程提高了化学入门课程的质量，提高了理科学生的保留率，并减轻了社区学院学生进入四年制院校的过渡。 为学生和教师提供“虚拟”傅里叶变换红外（FT-IR）仪器的交互式教学软件已经开发出来。 目前正在为虚拟傅里叶变换核磁共振仪开发类似的软件。 该软件可作为教师介绍光谱学方法的辅助教材，也可作为FT-IR和FT-NMR仪器的使用指南。对于实际的实验室课程，学生可以将自己实验中的样品提交给区域中心进行FT-IR和FT-NMR测量。 每个样本的数据都存储在互联网文件服务器上，供学生在本地下载。 这个文件服务器提供了对仪器的合理访问，这是许多社区学院和私立学院通常没有的。 通过为学生提供现代仪器和解释自己的实验数据的经验，该计划正在提高他们对重要化学概念的理解。 此外，学生们正在深入了解这一科学过程的协作性质。 *
