Improvement of Undergraduate Laboratory Experiences with UV-Vis Spectrophotometry

化学（12）化学系正在将目前一学期的生物化学课程增加到两学期的课程，两个学期都有实验室。长期目标是在学院发展生物化学专业。 实验从教育文献正在扩大和修改，以介绍学生光谱分析在基础物理科学的核心课程。 紫外-可见分光光度计被用于与核酸结构分析、蛋白质分析和动力学相关的实验中。该项目正在加强化学课程，在理科和非理科专业的讲座和实验室课程中增加使用现代技术。学生们通过进行与电子跃迁和分子轨道相关的分析来学习分子结构，并研究结构特征对这些分析的影响。在有机实验室中，仪器的实际使用始于对从植物中提取的叶绿素进行表征。学生学习环境和生物化学应用，如DNA的热变性，以及分析/环境化学课程中的多组分分析。新的法医学应用正在开发中。该仪器支持我们的学生在本科研究项目的兴趣日益增长，建立进一步的连接，学习科学是如何做的，使他们更好地准备研究生院和工业就业的化学。该项目将通过介绍、在国际化学研究和化学教育期刊上发表文章、万维网以及在科学会议上与教育工作者互动等方式传播项目成果，从而影响外部受众。该项目的成功将取决于建立两个学期的生物化学课程与实验室，学生课程评估，采取本科生研究项目，正式演示，出版物和survey.PROJECT数据表和项目摘要的专业数量化学系计划增加目前的一个学期的讲座只有生物化学课程与实验室在两个学期的两个学期的课程。长期目标是在学院发展生物化学专业。紫外-可见分光光度计的获得将允许包括与核酸结构分析、蛋白质分析和动力学相关的实验。该项目将加强化学课程，在理科和非理科专业的讲座和实验室课程中增加现代技术的使用。学生将通过进行与电子跃迁和分子轨道相关的分析来学习分子结构，并研究结构特征对这些分析的影响。该仪器的实际操作将开始在有机实验室从植物中提取叶绿素的特性。学生将学习环境和生物化学应用，如DNA的热变性，以及分析/环境化学课程中的多组分分析。将开发新的法医科学应用。该仪器将增加我们的学生在本科研究项目的兴趣日益增长，在学习科学是如何做，使他们更好地准备研究生院和工业就业化学建立进一步的连接。该项目将通过介绍、在国际化学研究和化学教育期刊上发表文章、万维网以及在科学会议上与教育工作者互动等方式传播项目成果，从而影响外部受众。该项目的成功将由两个学期的生物化学课程与实验室，学生课程评估，采取本科研究项目，正式演示，出版物和调查的专业数量的建立确定。

Chemistry (12) The Department of Chemistry is augmenting the current one-semester lecture-only Biochemistry course to a two-semester course with laboratories in both semesters. The long-term goal is to develop a Biochemistry major at the College. Experiments from the educational literature are being extended and modified in order to introduce students to spectroscopic analysis in the basic physical science core courses. A UV-Vis spectrophotometer is being used in experiments relating to nucleic acid structure analysis, protein analysis, and kinetics. The project is strengthening the chemistry curriculum by adding to the use of modern technology in lecture and laboratory courses for science and non-science majors. Students are engaged in learning about molecular structure by conducting analyses relating to electronic transitions and molecular orbitals, and studying the effects of structural features on these analyses. Hands-on use of the instrument begins in the Organic laboratory with the characterization of chlorophylls extracted from plants. Students study environmental and biochemical applications, such as thermal denaturation of DNA, and multicomponent analysis in the Analytical/Environmental Chemistry course. Novel forensic science applications are being developed. The instrument is supporting the growing interest of our students in undergraduate research projects, establishing further connections in learning how science is done and making them better prepared for graduate school and industrial employment in chemistry. The project will influence an outside audience with dissemination of project results through presentations, publications in international chemistry research and chemistry education journals, the World-Wide Web, and interactions with educators at scientific meetings. The success of the project will be determined by the establishment of the two-semester Biochemistry course with laboratories, student course evaluations, the number of majors taking undergraduate research projects, formal presentations, publications, and surveys.PROJECT DATA FORM AND PROJECT SUMMARYThe Department of Chemistry plans to augment the current one-semester lecture-only Biochemistry course to a two-semester course with labs in both semesters.
