Statewide Use of the Internet and Simulation Software for Accessing Modern Instrumentation

该项目通过在本科课程中使用现代仪器来更新化学入门课程。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，并为社区大学学生进入四年制院校提供了便利。为学生和教师提供“虚拟”傅立叶变换红外(FT-IR)仪器的交互式教学软件已经开发完成。用于虚拟傅里叶变换核磁共振(FT-核磁共振)仪器的类似软件目前正在开发中。该软件可被教师用作介绍光谱方法的讲授辅助工具，以及FT-IR和FT-核磁共振仪器的使用教程。对于实际的实验室课程，学生可以将他们自己的实验样本提交到地区中心进行FT-IR和FT-核磁共振测量。每个样本的数据都存储在Internet文件服务器上，供学生本地下载。该文件服务器提供了对仪器的合理访问，这是许多社区大学和私立大学通常不具备的。通过为学生提供现代仪器的经验和对他们自己的实验数据的解释，这个项目正在加强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。*

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. *
