The Spectroscopic Workstation: A Tool for Education in Universities with Limited Instrumentation

该项目包括组装各种组件(光学和电气)，以创建一个“光谱工作站”(SW)。该工作站提供各种光谱仪器的教学质量版本。这种方法允许更高效、重复使用设备，而不是更有限地使用专门的仪器。短波的使用允许以较低的每个实验的资本投资开发范围广泛的光谱实验。因此，这种方法对教师很有吸引力，因为它减少了经常限制他们创造力的财务限制。此外，该方法还鼓励学生不要把乐器简单地视为“黑匣子”。除了为软件开发硬件外，该项目还为仪器分析和物理化学实验室开发了基于软件的课程。这些课程使用软件来加强对如何进行测量、光谱仪如何工作以及仪器设计与测量质量之间的关系的理解。已特别注意开发课程，以培养实验设计技能，并鼓励整合物理、数学和化学的知识。这种方法应该让学生更直接地对实验室工作的所有组成部分负责，从而让他们参与进来。这一方法的成功正在通过学生问卷进行评估，调查问卷旨在确定学生对其学习经验的看法。目前正在提供该项目的成果，包括实验室手册和设备清单。*

This project involves the assembly of a variety of components (optical and electrical) to create a "spectroscopic workstation" (SW). This workstation is providing teaching-quality versions of a wide range of spectroscopic instruments. This approach allows more efficient, repeated use of equipment, rather than more limited use specialized instrumentation. The use of SW allows the development of a wide range of spectroscopic experiments at lower capital investment per experiment. Thus, the approach is attractive to instructors because it reduces the financial constraints which often limit their creativity. In addition, the SW-approach encourages student not to treat instruments simply as "black boxes". In addition to developing the hardware for the SW, this project is developing a SW-based curricula for instrumental analysis and physical chemistry laboratories. These curricula use SW to reinforce an understanding of how measurements are made, how spectrometers work, and the pelationship between instrument design and measurement quality. Special attention has been given to developing curricula that foster experimental design skills and encourage integration of knowledge from physics, mathematics, and chemistry. This approach should engage students by making them more directly responsible for all components of their laboratory work. The success of this approach is being evaluated by student questionnaires designed to determine the students' perceptions of their learning experience. the results of this project, including laboratory manuals and equipment lists are being made available. *
