Incorporation of Computer Modernized Cary-14 UV/Vis Spectrophotometer in the Undergraduate Curriculum

化学(12)这个项目旨在通过将高分辨率、计算机控制的紫外-可见-近红外(UV-VIS-NIR)光谱学纳入三门高级实验室课程：仪器分析、无机合成和实验物理化学，来加强该机构的本科生化学课程。这是通过将化学教育文献中的几个新的或经典的实验室实验改编成用于计算机化的CARY-14，并将其落实到化学系目前教授的三门正规实验室课程中来实现的。拟议的实验和仪器可提高学生的批判性思维能力，增加他们对各种计算机化设备的熟悉程度，并使他们接触到通过调查进行科学探究的过程。由于课程的这一正式变化，学生们更好地准备参与独立研究。该机构是一个综合的，城市，通勤的校园，学生人口种族多元化，化学系反映了这种多样性。Funding为Aviv Instruments提供了当前CARY-14分光光度计的现代化，包括电池外壳中的热电冷却加热器，以及PI和co-PI的释放时间，以便为CARY-14和我们的实验室课程实施和调整实验。该项目为期33个月，因为第一年的大部分时间都用于仪器现代化和实验室实验的初步开发。这些实验在拨款的第二年被引入正式的实验室课程，然后在最后一年进行评估、修改和重新引入。这一建议的预期结果包括：1)改进本科实验室实验；2)减少数据获取时间；3)增加数据解释和分析时间；4)增加对数字数据获取的理解；5)增加实验室实验的种类和质量；6)增加每个学生的动手时间；7)将数字方法-仪器输出以及Microsoft Excel、Word和PowerPoint-整合到实验结果报告中。这个项目极大地提高了我们的专业为研究和未来在学术界和工业界就业做好准备。成果的传播是通过链接到化学系主页的网站、在参考的化学教育期刊上发表以及在区域和国家会议上介绍来实现的。

Chemistry (12)This project seeks to enhance the undergraduate chemistry curriculum at the institution by incorporating high resolution, computer-controlled ultraviolet-visible-near infrared (UV-Vis-NIR) spectroscopy into three upper-level laboratory courses: Instrumental Analysis, Inorganic Synthesis, and Experimental Physical Chemistry. This is accomplished by adapting several new or classic laboratory experiments from the chemical education literature for use with the computerized Cary-14 and implementing them into the three formal laboratory courses currently taught by the Chemistry Department. The proposed experiments and instrumentation enhance the students' critical thinking skills, increase their familiarity with a wide variety of computerized equipment, and expose them to the scientific process of inquiry through investigation. As a result of this formal change in curricula, the students are better prepared to participate in independent research. The institution is a comprehensive, urban, commuter campus with an ethnically diverse student population and the chemistry department reflects that diversity. Funding provides an Aviv Instruments modernization of the current Cary-14 spectrophotometer including a thermoelectrically cooled heater in the cell housing, and release time for the PI and co-PIs to implement and adapt experiments for the Cary-14 and our laboratory courses. This project is for a duration of 33 months, as much of the first year is devoted to the instrument modernization and initial development of the laboratory experiments. These experiments are introduced into the formal laboratory courses in the second year of the grant, then evaluated, revised and reintroduced in the final year. The anticipated outcomes of this proposal include: 1) improved undergraduate laboratory experiments; 2) decreased time for data acquisition; 3) increased time for data interpretation and analysis; 4) increased understanding of digital data acquisition; 5) increased variety and quality of laboratory experiments; 6) increased hands-on-time for each student; and 7) integration of digital methods-instrumental output as well as Microsoft Excel, Word, and PowerPoint-into the reporting of experimental results. This project significantly improves the preparedness of our majors for research and future employment in academics and industry. Dissemination of results is accomplished through a web site linked to the chemistry department home page, publication in referred chemical education journals, and presentation at regional and national meetings.
