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

该项目涉及各种组件（光学和电气）的组装，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。这种方法可以更有效地重复使用设备，而不是更有限地使用专门的仪器。使用SW可以以较低的资本投资开发广泛的光谱实验。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政限制。此外，sw方法鼓励学生不要简单地将乐器视为“黑盒子”。除了为SW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SW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关系的理解。特别注意开发课程，培养实验设计技能，鼓励物理、数学和化学知识的整合。这种方法应该通过让学生更直接地负责他们实验室工作的所有组成部分来吸引学生。这种方法的成功是通过学生问卷来评估的，这些问卷旨在确定学生对他们的学习经历的看法。目前正在提供该项目的结果，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. *
