This project incorporates the use of UV-VIS spectrophotometers into the chemistry curriculum in order to modify the laboratory emphasis of lower division chemistry and promote student design and conduct of experiments and application of technological tools. Creativity and relevance are improved by coupling an early introduction of spectroscopic instrumentation with biochemical subject matter. Our first goal is to adapt introductory chemistry to involve course content guided by laboratory experimental work in which students, under faculty guidance, design and carry out fundamental chemical exercises (stoichiometry, equilibria, bioseparations, quantitative bioanalysis) with central spectroscopic applications. A second goal is to incorporate biochemical content at the introductory level, and to increase its emphasis at other points outside of formal biochemistry/cell biology courses. A third goal is to increase student knowledge and application of spectroscopy to questions of chemical structure and analysis throughout the chemistry curriculum and with increasing sophistication at the latter stages (fast acquisition kinetics, global spectral analysis, reaction mechanisms), and to increase support for undergraduate research. The two-year project involves all chemistry faculty in the department. The project overall is moving to a course structure built around student or student-team laboratory inquiries integrated with guided discussions led by faculty and, to do so, is adapting methods and procedures developed by the New Traditions Chemistry Initiative, centered at the University of Wisconsin. The project models work published in the Journal of Chemical Education on the importance of the early introduction of spectroscopic principles into the curriculum. The project also adapts a number of methods and experiments found in the Journal of Chemical Education and uses these to create the curriculum-wide emphasis on spectroscopy. New exercises in introductory chemistry, and upper division changes, are being introduced and evaluated starting in the first year and continuing thereafter. Both are being continuously redeveloped based on student responses to the methods and experiences. Introductory chemistry is a core curriculum course, so the changes target science and non-science majors. Science students are expected to be better prepared for higher division classes while generally becoming more technologically competent.

该项目将紫外-可见光谱仪的使用纳入化学课程，以修改低年级化学实验室的重点，促进学生设计和进行实验以及技术工具的应用。通过将早期引入的光谱仪器与生物化学主题相结合，提高了创造力和相关性。 我们的第一个目标是适应介绍化学涉及实验室实验工作指导的课程内容，在教师的指导下，学生设计和进行基本的化学练习（化学计量，平衡，生物分离，定量生物分析）与中央光谱应用。 第二个目标是将生物化学内容纳入入门级，并在正式生物化学/细胞生物学课程之外的其他点上增加其重点。第三个目标是增加学生的知识和光谱学的化学结构和分析的问题，在整个化学课程和日益复杂的后期阶段（快速采集动力学，全球光谱分析，反应机制）的应用，并增加对本科研究的支持。这个为期两年的项目涉及系里所有的化学系。 该项目总体上正在转向一种围绕学生或学生团队实验室调查与教师领导的引导讨论相结合的课程结构，为此，正在调整以大学为中心的新传统化学倡议开发的方法和程序。威斯康星州。 该项目模型的工作发表在化学教育杂志上的重要性，早期引入光谱原理到课程。 该项目还采用了《化学教育杂志》中的一些方法和实验，并利用这些方法和实验来建立全学院对光谱学的重视。 在介绍化学新的练习，和高司的变化，正在介绍和评估开始在第一年，并继续之后。两者都是不断重新开发的基础上，学生的反应的方法和经验。《化学导论》是一门核心课程，因此，《化学导论》的改革对象是理科和非理科专业。理科学生预计将更好地准备更高的部门类，同时普遍成为更技术能力。
